END OF SECTION 01 11 00

The National Mall and Memorial Parks (NAMA) supports several District of Columbia (DC) avian and mammal species of greatest conservation need (Table 1). Most birds at NAMA are protected by the Migratory Bird Act. In addition, Executive Order 13186 (2009), directs Federal agencies to minimize negative impact to birds and promote conservation. Since birds nest in locations other than trees, such as bare ground and shrubs, construction projects should consider the entire project area and inspect for nesting birds and other denned/roosted wildlife. Table 2, not only highlights the U.S. Fish and

Wildlife Services’ list of birds of conservational concern, but where these species nest. Although NAMA is not occupied by any federally threatened or endangered species it is adjacent to critical habitat for the endangered Atlantic Sturgeon (Acipenser oxyrinchus oxyrinchus) and the threatened Northern long-eared bat (Myotis septentrionalis) has been documented within NAMA boundaries, although the extent of it’s occupation is unknown.

We suggest the following recommendations for tree/shrub removal to ensure compliance with

The Migratory Bird Act (1918), The Bald and Golden Eagle Protection Act (1940), and District of

Columbia regulations (2015):

To protect migratory birds, tree/shrub removal should not occur between March 15 – August 15.

If this can not be accommodated, a survey will be conducted to ensure that the trees/shrubs to be removed do not contain any nesting birds (eggs/nestlings). If an active nest is found, all work must stop, and the natural resources program manager should be contacted immediately. Please see Appendix A for additional information regarding construction and bird conservation provided by the U.S. Fish and

Wildlife Service. There are also species-specific guidelines:

• Bald eagle: December 15th – July 15th, 0.25 mile buffer around the nest, during breeding season, restricting vehicle/pedestrian access.

• Black-crowned night heron: (listed as Tier Priority 1 for D.C. Species of Greatest

Conservation Need 2015, Table 1) nesting restrictions are April 1 – August 15, activities should be restricted within 0.25 miles of the rookery and maintain undisturbed vegetated buffer of at least 500’ around rookery.

To protect bats in the area, roosting trees and a 150-foot radius buffer will have no tree removal, or other disturbance within the zone, between June 1st and July 31st. If this can not be accommodated a survey will be conducted to ensure that the trees to be removed are not utilized by roosting bats. Bat monitoring should be conducted ½ hour before sunset, and 1 hour after. Common bat sign can be found in Appendix B. If an active bat roost is found, all work must stop, and the natural resources program manager should be contacted immediately. The northern long-eared bat was listed as a federally

threatened species in 2015. Although, roosting trees for northern long-eared bats have not been identified in NAMA, Rock Creek Park and other parks within the National Capital Area have known roosting areas.

Northern long-eared have been detected during the last acoustic monitoring survey at NAMA (2016-

2018), so monitoring is imperative if trees are being removed/pruning from June 1 – July 31.

*Category for Concern

1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands);

2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and

3. "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing).

Pruning trees and shrubs

When pruning, you should modify your work to not disturb, injure, or kill protected wildlife (Tree Care Industry Association, 2017). The following information on tree and shrub pruning has been adapted from “Tree Care for Birds & Other Wildlife, Best Management Practices in California” (2018) and “Avoiding Impacts on Nesting Birds, Best Management Practices, Vegetation and Construction Projects” (2016).

Dates for pruning follow the guidelines for tree/shrub removal listed above.

1. Plan work accordingly to avoid bird/bat breeding season (March 15 – August 15, for most bird species).

a. Birds and other wildlife not only utilize tree/shrub limbs as breeding/resting/foraging areas, but use tree cavities, leaves, bark, and standing dead trees (Figure 1). Regardless if a nest is present the tree/shrub may be providing nesting/denning habitat for wildlife.

2. If work is near a nesting bird/wildlife den, minimize disturbance in the area, especially during inclement weather.

3. If risk is managed and human safety is not an issue, consider keeping dead or dying trees since they provide habitat for insects/birds/wildlife. Different pruning techniques can be used to reduce the risk to human safety while still preserving the snag for wildlife habitat (Figure 3). If all branches are unsafe, remove the branches and leave the trunk.

Laws Protecting Birds

Migratory Bird Treaty Act (1918): Makes it illegal for anyone to take, possess, import, export, transport, sell, purchase, barter, or offer for sale, purchase, or barter any migratory bird, or the parts, nests, or eggs of such a bird except under the terms of a valid permit issued pursuant to Federal regulations.

The Bald and Golden Eagle Protection Act (1940): Prohibits anyone, without a permit issued by the

Secretary of the Interior, from “taking” bald eagles, including their parts, nests, or eggs. There are criminal penalties for persons who “take, possess, sell, purchase, barter, offer to sell, purchase or barter, transport, export or import, at any time or any manner any bald eagle… [or any golden eagle], alive or dead, or any part, nest, or egg thereof.” The Act also defines “take” as “pursue, shoot, shoot at, poison, wound, kill, capture, trap, collect, molest or disturb.”

Executive Order 13186 (2001): Support bird conservation by enhancing or restoring habitat, reducing negative impacts, integrate migratory birds in educational activities, etc. A memorandum of understanding between the National Park Service and Fish and Wildlife Service was signed 04/10/2010.

District of Columbia Regulations (2015): Chapter 15 Title 19 Section 1574.5

A migratory bird shall be controlled only in accordance with the federal Migratory Bird Treaty Act (16

U.S.C. §§ 703-712) and its’ implementing regulations, and as follows:

(a) A nest with eggs or young may not be moved, relocated, destroyed, or altered in any way without first obtaining a federal permit.

(b) A nest with no eggs or young may be removed from structures such as boats, docks, and construction equipment, or relocated without a federal permit.

Appendix A. Nationwide Standard Conservation Measures for Construction Sites, U.S. Fish and

Wildlife Service.

NATIONWIDE STANDARD CONSERVATION MEASURES

Listed below are effective measures that should be employed at all project development sites nationwide with the goal of reducing impacts to birds and their habitats. These measures are grouped into three categories: General, Habitat Protection, and Stressor Management. These measures may be updated through time. We recommend checking the Conservation Measures website regularly for the most up-to-date list.

1. General Measures

a. Educate all employees, contractors, and/or site visitors of relevant rules and regulations that protect wildlife. See the Service webpage on Regulations and Policies for more information on regulations that protect migratory birds.

b. Prior to removal of an inactive nest, ensure that the nest is not protected under the Endangered Species Act (ESA) or the Bald and Golden Eagle Protection Act (BGEPA). Nests protected under ESA or BGEPA cannot be removed without a valid permit.

i. See the Service Nest Destruction Policy

c. Do not collect birds (live or dead) or their parts (e.g., feathers) or nests without a valid permit. Please visit the Service permits page for more information on permits and permit applications.

d. Provide enclosed solid waste receptacles at all project areas. Non-hazardous solid waste (trash) would be collected and deposited in the on-site receptacles. Solid waste would be collected and disposed of by a local waste disposal contractor. For more information about solid waste and how to properly dispose of it, see the EPA Non-Hazardous Waste website.

e. Report any incidental take of a migratory bird, to the local Service Office of Law Enforcement.

f. Consult and follow applicable Service industry guidance.

2. Habitat Protection

a. Minimize project creep by clearly delineating and maintaining project boundaries (including staging areas).

b. Consult all local, State, and Federal regulations for the development of an appropriate buffer distance between development site and any wetland or waterway. For more information on wetland protection regulations see the Clean Water Act sections 401 and 404.

c. Maximize use of disturbed land for all project activities (i.e., siting, lay-down areas, and construction).

d. Implement standard soil erosion and dust control measures. For example:

i. Establish vegetation cover to stabilize soil

ii. Use erosion blankets to prevent soil loss

iii. Water bare soil to prevent wind erosion and dust issues

3. Stressor Management Stressor: Vegetation Removal Conservation Goal: Avoid direct take of adults, chicks, or eggs.

Conservation Measure 1: Schedule all vegetation removal, trimming, and grading of vegetated areas outside of the peak bird breeding season to the maximum extent practicable.
