1 Introduction Pollinators are essential to the United States economy. Honey bees, native bees, birds, bats, butterflies, and other species contribute substantially to our food production systems, the economic vitality of the agricultural sector, and the health of the environment. Honey bee pollination alone adds more than $15 billion in value to agricultural crops in the United States each year, and pollination by other species adds another $9 billion. In addition, pollinators support the success and vigor of flowering plants, making ecosystems stronger, more resilient, and enhancing the environment for human populations.

Decades of stressors have severely and adversely altered the health and numbers of pollinator populations. Pollinators have been impacted by the loss, degradation, and fragmentation of habitat, reduction in the number and quality of food sources, reduction in the availability of sites for breeding, nesting, and roosting, and improper use of pesticides and herbicides. In some case these stressors have made pollinator populations more susceptible to existing disease, predators, and parasites. The status of many pollinators is serious and efforts to improve their health through action on Federal facilities will support both the sustainability of our nation’s food production systems and the health of the environment.

On June 20, 2014, the President issued a memorandum1 directing the heads of executive departments and agencies to create a Federal strategy promoting the health of honey bees and other pollinators. The Presidential Memorandum envisioned broad engagement to improve the management of Federal buildings, landscapes, rangelands and forests to increase and improve pollinator habitat nationally. The expectation is for facility managers to actively examine their current buildings, grounds, and practices for opportunities to transition to a richer diversity of pollinator-friendly plant species, improving the sustainability of Federal landscapes and serving as an exemplar for public-private partnerships, outreach, and education.

Section 3(d) of the Presidential Memorandum instructs the Council on Environmental Quality (CEQ) to revise its guidance for Federal agencies to incorporate pollinator-friendly practices into site landscape performance requirements. Through the support and efforts of a multi-agency working group, this addendum to the Sustainable Practices for Designed Landscapes (Sustainable Landscapes)2 provides guidance and recommendations for creating and maintaining quality habitats for pollinators in new construction, building renovations, landscaping improvements, and in facility leasing agreements at Federal facilities and on Federal lands.

The White House Council on Environmental Quality. www.whitehouse.gov/administration/eop/ceq/sustainability/landscaping-guidance.

www.WhiteHouse.gov

The recommendations in this document should be considered in conjunction with the Sustainable Landscapes guidance, and with regard to the sustainability goals set forth in Executive Order 13514: Federal Leadership in Environmental, Energy, and Economic Performance. The Addendum is an integral companion to parallel instructions in the Presidential Memorandum to the General Services Administration (GSA) to incorporate pollinator friendly practices into its guidance documents for public building construction, and to the U.S. Departments of Agriculture and Interior to develop best management practices to enhance pollinator habitat on Federal lands.

1.1 Applicability

These guidelines apply to all Federal agencies and activities that are subject to the provisions of Executive Order 13514. They do not supersede laws, regulations or applicable agency requirements that may be more specific or more stringent. The Addendum applies to agencies constructing new or rehabilitating existing owned or leased facilities, or otherwise implementing landscaping practices on agency-owned or leased land or space. It supports pollinator habitat, beyond the building footprint, in agency efforts to meet the goals of the National Pollinator Health Strategy.

1.2 Background

The breadth, severity, and persistence of pollinator losses poses significant challenges.

The combination of stressors upon pollinator populations, including loss of natural habitat and forage, mite infestations and introduced diseases, reduced genetic diversity, and exposure to pesticides and other chemicals3 have amplified the situation.4 For example, 2014 revealed a record low population of migrating monarch butterflies and the lowest number of honey bee colonies in the United States in 50 years. For these reasons, the Presidential Memorandum commits agencies to make swift changes to counteract risks and, most importantly, restore pollinator populations.

Landscaping can be a powerful tool to help our Nation’s pollinators. A multitude of daily decisions are made regarding the planning, preparation, design, maintenance of the approximately 43 million acres5 of designed landscape associated with Federal facilities. These decisions range from local pathway and flower bed designs, building and facility landscapes, to acres of right-of-way, rangeland, and forest habitat under management. All of these routine, or not so routine, decisions by Federal agency managers provide valuable opportunities to advance pollinator health and habitats, and to support natural ecosystem functions.

3 For the purposes of this document, “pesticides” and “chemicals” broadly refers to the use of insecticides, herbicides, and fungicides.

4 Presidential Memorandum — Creating a Federal Strategy to Promote the Health of Honey Bees and Other Pollinators. The White Office of the Press Secretary. www.whitehouse.gov/briefing-room/presidential-actions/presidential-memoranda. www.WhiteHouse.gov 5 FY 2012 Federal Real Property Report. General Services Administration.

www.gsa.gov/portal/mediaId/179655/fileName/FY_2012_FRPP_intro_508.action

The Presidential Memorandum states that: “future landscaping projects at all Federal facilities shall, to the maximum extent appropriate, use plants beneficial to pollinators.”

Plants carry specific traits that attract pollinators to the available pollen and nectar. In turn, pollinators help the plants to reproduce by carrying pollen from one flower to the next.

This Addendum aims to empower facility managers with sufficient understanding and expert resources to re-appraise existing practices. The objective is to promote the overall lifecycle of pollinators at Federal facilities - improved foraging, reproduction, shelter, and hibernation - while removing barriers that may block an agency’s ability to create and maintain quality habitats. These improvements can be achieved within existing facilities’ budgets, such as transitioning from a barren monoculture (i.e., lawns) with expensive maintenance needs to a low-maintenance, wild-flower, meadow or prairie.

1.3 Scope

Recommendations within this document concern “designed” sites, paths, walkways, and spillways adjacent to a facility owned and/or operated by the Federal government.

An applicable outdoor area may include, but is not limited to, the following:

Building entryway systems Tree boxes and planters Pedestrian pathways Courtyards Campuses or facilities with accumulated acreage in open space or access roadsides Spillways adjacent to facilities

The intended audience is Federal landscape designers, Federal contracting officers, Federal facility managers, and other applicable team members who may be involved in the management of designed Federal landscapes. Lease construction should incorporate requirements as feasible. As noted earlier and emphasized in the Presidential Memorandum, parallel Federal guidance and best management practices have also been prepared for Federal building construction (GSA) and range/forest land management (USDA, Interior).6

Agencies should strive to balance practices to improve pollinator health with other needs, e.g., security and sustainability, while considering cultural, esthetic, recreational, and environmental resources inherent to the landscape. The guidelines are intended to enhance, and not to inhibit or restrict, planning, operations, and maintenance of landscapes surrounding Federal buildings.

1.4 Performance Measurement

Goals, targets, milestones, and measures assess progress and provide useful insights on the success and opportunities available for a site. Managers should utilize a team to identify these performance measures at the design stage. Examples of metrics could include: square footage or acreage converted to pollinator-friendly habitat for nesting or foraging, capital and maintenance costs pre and post planting, number of plant species, diversity and abundance of pollinators, frequency of visits, periods of bloom for the plant species, and external collaborations including volunteer support. Multiple measures allow for a comprehensive assessment of progress. Facility managers should look to agency leads to identify additional measures.

1.5 Partnerships and Citizen Engagement

Federal action can do much to increase pollinator habitat acreage and quality, but Federal action alone is not sufficient to restore populations to healthy levels.

Recognizing this, the Presidential Memorandum on Pollinator Health emphasizes the importance of developing new public-private partnerships and strengthening citizen engagement. Federal facility managers are encouraged to identify appropriate partnerships and engagements with local, state, regional, and/or national organizations as valuable enhancements to direct Federal action.

Partnerships can include agreements, contracts, or memoranda of understanding, and may help to overcome performance challenges, connect a facility to the broader pollinator effort, and/or facilitate access by volunteer groups to leverage community resources. Citizen scientists and groups such as Master Gardeners can provide valuable knowledge on regional native cultivars, training, pollinator assessments, evaluation measures, restoration efforts, research, and education outreach. Participation with community groups and in citizen science efforts also serves to amplify Federal actions to improve pollinator health through linkages to the broader community.

1.6 Framework and Objectives

The intent of this document is to provide Federal landscape designers and architects, contracting officers, facility managers, and other team members who may be involved in the management of Federal landscapes, with the administrative resources and tools to navigate the breadth of research available on pollinator habitat, and to make better decisions to support pollinator populations. This document covers a small window to some of the most common pollinators found throughout the continental United States.

It is focused on those pollinators with the greatest potential for recognition, attraction, and/or that are currently listed as endangered.7 In addition, best management practices are integrated throughout the guidance to serve as examples and resources for users.

www.fws.gov/pollinators/Programs/Endangered.html

The framework for the Addendum is as follows:

1. Procedures details pollinator-friendly practices and is organized by project phase – planning, design, construction, maintenance and management. At the design phase, project objectives should be clearly communicated to staff and the project team to facilitate decisions related to the long-term sustainability and goals of the agency. New strategies for a pollinator habitat should be addressed as soon as possible to allow for timely and balanced incorporation into annual planning and construction cycles. During the ongoing maintenance and management phase, active engagement provides the opportunity for tracking performance metrics and responding to results. The team may also find additional opportunities to enhance and support the pollinator habitat.

2. Outreach presents communication strategies for public-private partnerships and increased citizen engagement. Facilities managers are encouraged to identify appropriate partnerships and engagements with clubs and associations as valuable enhancements to direct Federal action.

3. Educational Pollinator Guides includes snapshots of familiar pollinator species and examples of the plant species that support them. Use this section as a tool to help identify: pollinators, potential plant species, habitats, and behavioral characteristics.

4. Resources provides an aggregation of documents and websites referenced throughout the Addendum, as well as additional resources for further information.

2 Procedures The objectives and targets below recommend actions to support sustainable pollinator habitats and promote environmentally responsible designed landscape decisions.

Agencies should develop targets that best align with the scope of the project, as well as consider going beyond the following basic criteria to implement an ambitious pollinator habitat agenda.

2.1 Project Initiation, Design, and Construction

The design and construction of pollinator friendly habitats requires effective communication, the building of partnerships, and the development of clear, achievable goals. An example of this could be the creation of a pollinator habitat highlighted by signage that creates positive emotional responses by occupants and visitors.

Facility managers should, at a minimum, involve appropriate subject matter experts with necessary skills to develop goals and support the project. These skills can include strategic planning, asset or project management, landscape design and architecture, construction management, and facility maintenance and operations.

The project team should:

Be aware of, and reflect on, the agency’s mission, design guidelines, sustainable design goals, and climate-related or other vulnerabilities for the site.

Identify and coordinate existing and applicable documents, plans, and guidelines into design requirements.

Know the habitat, paying attention to current conditions to develop a sense for changes and growth in pollinator numbers.

Develop goals, milestones, and metrics for comprehensive performance evaluation, communicating these goals and metrics to appropriate parties and team members.

Reconfirm measures and benchmarks and, if applicable, ensure their inclusion in final construction documents.

The importance of communication cannot be overstated. Many stakeholders are unfamiliar with the plight of pollinators. Personnel and building occupants can be both supporters and beneficiaries of a project’s outcomes, so early engagement with these groups is the most critical time to influence the project’s success.

During the construction phase of a project, the project team should review and confirm project specifications, budget requirements, and pollinator habitat improvements. It should also request the use of high-quality, durable, non-toxic products and materials.

For example, avoid materials containing paints and other surface coatings which contain toxic substances. Understanding ingredients and materials within products is critical to improving pollinator habitat.

The Sustainable Landscapes guidance provides additional actions and strategies related to design and construction. Review the following sections within the existing guidance:

Site Selection and Planning, Soils, Water, Vegetation, Materials, Human Health and Well-being, and Construction. The recommendations below are pollinator-driven strategies that should be implemented in conjunction with the original Federal sustainability guidance.8

2.1.1 Planning and Preparation

Planning

A Federal designed landscape is one that is professionally laid to fulfill a specific function. Begin with a project assessment including: site function, existing conditions, site resources, and opportunities for developing a pollinator-friendly habitat.

Consider the availability of water, amount of sunlight, current and desired vegetation diversity. This preliminary review helps to identify site constraints, opportunities, and sensitive conditions that can be incorporated into the decision-making process.

As a general point, many native pollinator plant species thrive in full sunshine and local soils, providing valuable opportunities to capitalize on sunny, hot, and exposed locations. By gathering as much information as possible during the start of the design process, project teams can understand the site’s human-environmental-pollinator relationships and create opportunities for the health and well-being of pollinators.

Opportunity for Improved Design

Following the construction of a security wall, this Smithsonian Institution site relied on planning and preparation to restore a high profile area. Compost was tilled into the soil to address compaction. Small plugs and one gallon containers of native plants were added. Once complete, all plants were labeled as a resource and point of inspiration for visitors.

Preparation

Site preparation is critical. Prior to sowing, it is important to determine whether the project site will support suitable growing conditions. In particular, emphasis must be placed on removing competing vegetation and breaking the existing growing cycle of invasive species. Thriving invasive species will burden attempts to grow a prosperous pollinator habitat.

Depending on a project size, first determine if it is possible to physically remove the undesirable plants – pulling, mowing, burning, or tilling. In some cases, such as with larger facility acreage, invasive species can only be killed using herbicides that often require more than one season of effort.9 Implementation strategies can range from small-scale grassland conversion (weeding, plastic coverage, herbicides, cover crop, mulch) to larger facility acreage (herbicides, interspersing within monoculture grass).

Sometimes a combination of removal methods is most effective.

Whichever method is chosen, proper site preparation must be taken before sowing native seeds, as non-selective herbicides should not be applied after seeds are sown. It is likely that the site may appear a bit lean for a couple of years until native grasses and species lay deep roots. Signage or other efforts to communicate the project and progress reporting should be incorporated in the preparation process. This helps to keep people informed and aware of any risks, next steps, and objectives for the project. Refer to Section 3, “Outreach”, for additional guidance on signage materials.

Refer to Section 2.2.1, “Landscape Management Principles” for continued guidance on the removal and management of invasive species and refer to the original Sustainable Landscapes10 guidance for further information on site planning and soils.

Project Kick-Off:

Use a project kick-off meeting to ask the right questions and launch an integrated process to support the long-term effectiveness of a project. Such a meeting should:

Define purpose and goals.

Build facility ownership through communication and partnerships.

Design a business plan with budget and funding options.

Include “Protection of Flora and Fauna” specifications in any general project specifications.

Prepare turf/landscape protection plan with established tree protection zones in project drawings.

Estimate landscape restoration requirements such as tree replacement costs.

Consider habitat or landscaped areas when planning for a laydown area.

Identify pollinator education needs to raise environmental consciousness.

2.1.2 Plant Species for Pollinators

Landscapes that supports healthy pollinator populations can be functional and aesthetically pleasing. Pollinator-friendly landscapes may be formal or naturalistic in appearance. Good design and proper maintenance help to improve the landscape aesthetic and provides a focal point filled with color, texture, and seasonal interest as well as a rich and diverse wildlife habitat.

Plant Selection

1. Choose plants that support the forage, reproduction, shelter and/or hibernation of pollinators specific to your ecoregion.

2. Choose plants that are best for your ecoregion;

preferably native plants to which pollinators are most accustomed. Native plants evolved along with native pollinator species and are well adapted to thrive in local conditions. Pay particular attention to sunlight, moisture, and soil quality needs, as many native pollinator species thrive in direct sunlight without the need for irrigation or soil enhancement. These actions may prove detrimental by encouraging unwanted weed species. Using some non-native plants is acceptable as long as they are not considered invasive.

3. Seasonal variety is a major consideration.

Choose plants that bloom at different times across seasons. While it is important to consider periods of peak pollinator activity in an ecoregion, also have pollen sources available when little else is in bloom. For example, common witch hazel (Hamamelis virginiana) blooms October to December.

4. Consider all types of plants. There are trees, shrubs, vines, perennials, and annuals that contribute to pollinator habitats. With some planning it is easy to match your plants to the needs in the landscape. For example a hot and sunny entrance to a building may benefit greatly from a large shade tree with blooms to attract pollinators. Or a small highly visible area can be planted with attractive pollen rich flowers in display beds or containers.

5. Acquire seeds and plants from nurseries that do not treat their plants with systemic insecticides.

6. Take care when selecting plant cultivars.

Some plants are selected for traits attractive to humans but not pollinators (size, color, shape). Sometimes these selections or cultivars of plants lose the traits/indicators on which pollinators rely.

For instance the coneflower (Echinacea purpurea) and many of its cultivars are excellent for pollinators, whereas a number of double-flowered Echinacea cultivars have little appeal for pollinators. Therefore, prioritize the original native species whenever possible.

Habitat Strategies:

Water

Access to clean, shallow, water is necessary for a pollinator habitat.

During the design phase, determine water accessibility on a project site. If naturally occurring water is unavailable, consider alternative sources such as reclaimed water or rainwater. Granite boulders with shallow depressions hold water from the irrigation each morning and dry from evaporation by the end of the day. This method requires little maintenance, reduces concerns of long-term standing water, and their hefty weight keeps them free from vandalism or theft.

BEST PRACTICES – ALL REGIONS

Monarchs and Milkweeds

Milkweeds are obligate host plants for the monarch butterfly. Rose/swamp milkweed (Asclepias incarnata), common milkweed (Asclepias syriaca), and butterfly milkweed (Asclepias tuberosa) are widely distributed and easily grown species for attracting monarchs. The monarch must lay its eggs on plants within the milkweed family (top, left image).

The adult monarch (below, left) visits many different flowers for nectar, including milkweed, on its annual migration across North America.

Here, the adult monarch feeds from the boneset plant (Eupatorium perfoliatum).

Spring breeding for monarchs encompasses areas in most of Texas, Oklahoma, and part of Arkansas and Kansas. Monarchs arriving in this area during the annual migration from Mexico (in March) must lay eggs on milkweeds. The adults that develop as a result of this reproduction move northward into the summer breeding range in May and early June. This summer breeding area includes the upper Midwest (the eastern Dakotas, Minnesota, Wisconsin, Iowa, Illinois, Michigan, and parts of Indiana).

To date a total of 58 Native Plant and Pollinator Gardens have been established in the U.S. Forest Service’s Eastern Region national forests and tall-grass prairies.

All 15 Eastern Region Forests have developed at least one garden; some Forests have as many as 14 gardens, with one at each District Office.

Selected gardens offer docent tours and all are interpreted via signs. The gardens vary in size from 10 feet by 10 feet to 10 acres and serve a multitude of purposes. The native plants featured serve to illustrate nectar and larval food sources for both common and uncommon insect species – such as Monarch butterflies feeding on milkweeds and Karner Blue butterflies feeding on sundial lupine. The native plants propagated in these gardens significantly aid in the control of non-native invasive plants in rehabilitation and restoration efforts.

Water scarcity drove the U.S. General Services Administration to turn a resource consumptive turf "yard" into an efficient and evocative "garden" at Albuquerque’s Pete V. Domenici U.S. Courthouse.

The project was initially envisioned as a water conservation effort, but quickly evolved to become a comprehensive sustainable site works project. This Sustainable Sites Initiative (SITES)11 certified project rediscovered and reinterpreted the historical approach to clever and careful water stewardship, through water harvesting, storage, and redistribution. This allowed a new purpose-built landscape to emerge and be sustained through forethought and sensitivity to local conditions, rather than importing inappropriate landscape practices and overconsumption.

The original mono-cultural plant palette was replaced by a diverse range of high desert pollinator friendly native plants with prolonged seasons of bloom. Large expanses of site pavement materials were removed and crafted into site furnishings, and select building systems were integrated into the site. The result is a project that reclaimed an under-utilized interstitial space rendering it more useful and satisfying for both people and the environment.

2.2 Maintenance and Management

Pollinator habitats require a maintenance approach that may differ from conventional landscape efforts. Comprehensive maintenance practices should be developed that support the needs of the pollinators and provide for the landscape. Potential conflicts may arise between the needs of the pollinators and conventional aesthetic. For example, plants in a garden or habitat designed to promote pollinator health and food for caterpillars and other larvae are expected (and encouraged) to tolerate insect damage to plant leaves.

This section covers various tasks and timeframes that should be considered based on site objectives and needs. Maintenance and management activities could have a potential effect on the health and well-being of pollinators as well as the long-term sustainability and care of the pollinator habitats. Agencies should work with contractors, Federal maintenance staff, and landscapers to ensure the adoption and implementation of maintenance practices that enhance the health of pollinators and minimize risks from maintenance activities.

In general, the use of natural and mechanical strategies are preferred to the use of pesticides. However, for projects that involve extensive conversions of large land areas (e.g. waste sites, right of ways, and lawns) to natural grasslands and meadows, a well-managed plan likely includes the use of non-selective herbicides in order to remove invasive species. In such cases it is extremely important to involve a specialty consultant who is aware of ultra-low volume practices for invasive and pesticide application, and the ability to identify selective herbicides for the pest species

2.2.1 Landscape Management Principles

A least toxic approach to pest management should be employed. Chemical controls that can adversely affect pollinators should not be applied in pollinator habitats. This includes herbicides, broad spectrum contact and systemic insecticides, and some fungicides.

The management of pollinator-friendly habitats should be guided by the following principles.

1. An integrated pest management (IPM) program with reliance on physical, cultural, and biological controls should be used with a goal of managing pests not eradicating them. Review section 2.2.2 for further guidance.

2. If applicable, the site may need a strategic integrated vegetation management (IVM) plan. Similar to IPM, IVM relies on different types of controls to manage noxious plant species. Review section

2.2.3 for further guidance.

3. Allow for clover and other desirable plant material in turf and lawn areas. Limit mowing of turf areas to every other week.

4. Ensure proper timing for garden clean-up, cut-backs, and pruning. Because pollinators overwinter in different life-cycle stages and use plant material for overwintering sites, care should be taken to leave some structures in place to encourage full pollinator life-cycle in managed habitats. This includes timing cutbacks and garden cleanup to occur after pollinator emergence.

5. Care should be taken to source plant material from suppliers that can verify no insecticide treatments to their nursery stock. Insecticides can persist in plant material (leaves, flowers, nectar, and pollen) and lead to disruptions in a pollinator lifecycle once planted in the pollinator habitat.

6. Protect pollinator habitats from disturbances and stressors such as pesticide use, mowing or other site management operations. As above, this could include longer intervals between mowing to allow for clover and other lawn flowers to bloom, or setting aside areas of habitat that are only treated once or twice a year.

Habitat Highlights

When a pine tree died at the Smithsonian National Museum of Natural History, the trunk of the tree (snag) was kept as a wildlife habitat. The snag provides valuable habitat for insects and birds within a landscaped habitat.

An interpretive sign teaches visitors that this dead tree is actually an asset, providing important resources for the local ecosystem.

Non-noxious species that do not need to be removed or controlled can enhance habitat for pollinator and other beneficial insect species.12 When weeding activities need to occur, use physical weeding methods and other strategies, such as:

1. Accepted mulching practices (1-3” of mulch) to minimize the prevalence of weeds, thereby lessening the need for chemical control.

2. Use of perennial ground covers, which can be a suitable substitute for mulch and also help deter weeds.

3. Proper soil nutrition management in the form of soil nutrient testing prior to fertilizer application, which can help minimize issues of soil over-fertility that can lead to excessive weeds. Managers should keep in mind that native plants are likely adapted to the local soils and climate, and that increased fertilizer and water application may favor growth of undesirable weedy species.

2.2.2 Integrated Pest Management (IPM)

IPM is a pest management approach which includes biological, cultural, physical, and chemical tools in a way that minimizes economic, health, and environmental risks.

IPM is site-specific in nature, with individual tactics determined by the particular crop/pest/environment scenario. IPM places an emphasis on the reduction of pesticide use and the implementation of preventative and alternative control measures. Among these IPM practices, this subsection highlights biological controls as these are often overlooked.

Biological Controls

Biological Control is the reduction of plant pest populations by natural enemies and involves an active human role. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, and pathogens. Biological control agents work most effectively when pest populations are relatively low. They should be released at the first sign of pests in order to manage pest populations.

The adult stage of many insects with predaceous larvae (such as green lacewings and syphid flies) and many adult parasites feed only on pollen and nectar. Because pollinator landscapes have a variety of sequentially flowering species, they provide natural enemies with nectar, pollen, and shelter throughout the growing season.

Biological control agents can be ordered online and applied as needed. Once released, many biological control agents (green lacewings, parasitic wasps, lady beetles, etc.)

become established in pollinator landscapes particularly if you eliminate applications of harmful insecticides.

2.2.3 Integrated Vegetation Management (IVM)

IVM is a closely related concept to IPM. It can be viewed as a systematic approach to address undesirable plant species. An IVM program is generally defined as the practice of planning and promoting desirable, stable, plant communities that resist invasion by undesirable plants. These methods can include a combination of treatments, ultimately supplementing the competitive vitality of the desired plants with the most environmentally and cost effective methods to limit undesirable species.

This section touches on a variety of IVM methods: chemical, biological, cultural, and mechanical. The project team should consider all maintenance options during the selection, planning, and preparation phase of the project (Section 2.1.1). Method effectiveness, environmental impact, site characteristics, worker and public health concerns, security, and budget all play a role and should be considered, as appropriate.

When IVM is used, create a strategic vegetation management plan that identifies appropriate standards, site assessment, control, best management practices, criteria trained and licensed personnel, evaluation, and a tactical long-term maintenance plan.

Agencies should refer to the Accreditation Standards for Assessing IVM Excellence by the Right-of-Way Stewardship Council.13

Chemical Control

Within IVM programs, herbicides are judiciously applied in a focused, selective manner. Herbicides are used to eliminate invasive plants proven difficult to manage by hand or mechanical maintenance methods. Use herbicides that are approved by the U.S. Environmental Protection Agency (EPA) as safe and effective methods for controlling plants. No single

EPA Labeling Program

The EPA's Pollinator Risk Assessment Guidance is part of a long-term strategy to advance the science of assessing the risks posed by pesticides to bees, giving risk managers the means to further improve pollinator protection in our regulatory decisions. Among other things, the EPA anticipates the guidance will allow the Agency to assess effects from systemic pesticides quantitatively on individual bees as well as on bee colonies.

Resource: www2.epa.gov/pollinator-protection application method works as each situation requires advanced assessment to ensure that the safest, most efficient, and cost-effective chemical control program is chosen.

Biological Controls

This type of control uses living organisms to manage unwanted vegetation – often through destruction or competition. Biological control measures reduce interfering plant populations to manageable levels, rather than eradicating them completely.

Examples of biological control include: animals, plants, fish, insects, and disease organisms (e.g., bacteria, viruses, parasites, fungi, etc.). Selective application of herbicides that conserve grasses, herbs, shrubs, and compatible trees can also facilitate biological/ecological control.14

Cultural Control

Cultural control is the practice of using regeneration methods that create conditions appropriate for chosen species. Within IVM programs, this involves the introduction of specific plants or mulches to control vegetation growth or promote a desirable plant community. Examples of cultural control include:

1. Reintroduction of native species,

2. Use of weed barriers, such as hardscapes and weed mats, and

3. Use of mulch and compost.15

Select and plant only native species adapted to the site conditions. Agencies should monitor property frequently and eradicate small infestations before they become major problems. Active communication with neighbors can assist through educating them about the importance of learning how to identify and control interfering plants (see Section 3, “Outreach”, for additional information).16

Mechanical and Manual Controls

This approach involves targeted hand or machine removal of interfering plants. This can include, but is not limited to: mowing, cutting, grubbing, hand-pulling, girdling, tilling, and thermal control (i.e., prescribed burns).

Pollinator Protection Site Form

Integrate a pollinator protection plan into existing or new documents in order to minimize harm to pollinators and help to protect nearby habitats, food and water sources. Some pollinator protection practices could be to:

Become familiar with markings and indications that designate the presence of pollinators. For example, flag areas that contain pollinator damage to leaves so that insecticides aren’t applied by mistake. Pollinators such as butterflies (caterpillars) and leaf-cutter bees use plants for feeding and habitat purposes.

Adhere to all pesticide label instructions and treat only the target areas.

Observe pollinator activity to minimize exposure. Avoid applications to flowering plant species since this is when pollinators are actively foraging. Target very early morning or late in the evening applications.

Use an IPM approach that includes a pollinator protection plan.

IPM is a pest management approach that includes biological, cultural, physical, and chemical tools in a way that minimizes economic, health, and environmental risks. IPM places an emphasis on the reduction of pesticide use and the implementation of preventative and alternative control measures.

Cooperate and communicate with others. This includes neighboring sites that may be home to sensitive occupants or pollinator habitats, such as beehives. Monitor environmental conditions and use equipment that minimizes spray drift to adjacent sites.

Follow notification requirements if pollinator toxic pesticides (PTPs) are planned for application in close vicinity to hives or active pollinator activity, and become familiar with applicable regulatory agencies to report suspected pollinator pesticide poisonings.

Site. André Bluemel Meadow River Farm; Alexandria, VA

In 2003 AHS began a five year process to turn four acres of lawn at its River Farm headquarters into a meadow.

Most of the nearly 100 different species of grasses and herbaceous perennials planted in the meadow are native to eastern North America. By including a great variety of plants, the meadow attracts and hosts a diverse array of insects, birds, reptiles, amphibians, and mammals throughout the year. AHS used a four step method to establish the meadow:

Step 1. Eliminate Weeds Weeds can be eradicated by a variety of methods, including repeated tilling, smothering with newspaper, solarization, and herbicides.
