I. APPLICATION INFORMATION:

All pesticide applications shall be in accordance with the State of Oregon Department of Agriculture standards, product labels, and the Integrated Invasive Plant Management on the Roseburg District Environmental Assessment (DOI-BLM-ORWA-R000-2021-0004-EA). Where there are discrepancies between the sources listed above, the strictest/most restricting guidance/policy/law shall be followed.

Application Date(s): January 1st – December 31st, contingent upon weather conditions.

Method of Application: Herbicide applications will primarily be spot treatments and will be conducted using backpack sprayers, handheld sprayers, or a UTV or truck-mounted tank and pump system using a hand-controlled sprayer. Spot treatments may also be conducted via injection, frill, hack-and-squirt, cut stump, wick, and similar treatment methods.

Broadcast treatments would be conducted using backpack sprayers or with vehicle-mounted spraying systems using handguns, boom-less nozzles, or booms. Broadcast treatments would primarily occur along roadsides or other locations where invasive plant species have formed monocultures and would be conducted using selective herbicides. All broadcast treatments would be indicated as such in the Roseburg District Annual Treatment Plan and would be subject to additional review by the Roseburg District Interdisciplinary Team as indicated in the Roseburg IIPM EA.

rshowalt Text Box ATTACHMENT 4b_Roseburg District_Pesticide Use Permit PUP_Standard Operating Procedures_Tank Mixes and Application Rates

The choice of spray equipment will depend on total area infested, the distribution of invasive plant species on the landscape, the presence/absence of native and other desirable vegetation, and distance to water and other resource concerns.

No aerial applications will be conducted on Roseburg District.

Number of Applications: Most sites will be treated 1-2 times per year, though additional treatments may be necessary to treat individual plants inadvertently skipped during initial treatments, to expand treatment areas, or to apply a different treatment method if monitoring shows that treatments have not been successful. No treatments shall exceed the annual per acre maximums as stated on product labels and in the Roseburg IIPM EA.

A. PESTICIDE APPLICATION INFORMATION – Trade Names, Active Ingredients, Adjuvants, Mixes

The following active ingredients may be used in a single ingredient application or in an herbicide mix for nonnative invasive plant species treatments within the Roseburg District. Flexibility is desired as treatment sites are remote and formulation of an herbicide mix tailored to the specific weed target(s) and factors of the site allows the most effective treatment of the target species while minimizing non-target effects. Factors that are considered in designing an herbicide mix include target species, optimal treatment timing, phenology stage of the targets, non-target vegetation on site, and location of sensitive sites such as water or sensitive plant species.

A variety of trade names are included in each active ingredient description to allow use of purchased product over the duration of the proposal. All products listed below are formulations that are approved for use on Bureau of Land Management (BLM) lands according to the most recent national herbicide and adjuvants lists (January 29th, 2020). All pesticide Best Management Practices and Standard Operating Procedures are in accordance with the State of Oregon Department of Agriculture standards and the Integrated Invasive Plant Management on the Roseburg District Environmental Assessment (Roseburg IIPM EA).

1. 2,4-D

2,4-D is a plant growth regulator. It is a post-emergent herbicide that is selective for broadleaf plants. 2,4-D is formulated as an amine or an ester. Adding a small amount of an amine formulation of 2,4-D to a tank mix can often improve the effectiveness of other herbicides and reduce the likelihood of a population developing herbicide resistance. Tank mixes of 2,4-D and chlorsulfuron is effective on mustards and snapdragons, and tank mixes of 2,4-D and metsulfuron methyl are effective on field bindweed.

2,4-D is available in ester and amine formulations. Ester formulations have higher vapor pressures than amines, which results in increased volatilization. Some 2,4-D amine products have been developed as aquatic formulations, and are safe for fish at label application rates; the ester forms of 2,4-D can be highly toxic to fish and other aquatic organisms. An aquatic formulation of 2,4-D would be used when near standing and running water (including streams, wet ditches, etc.); aquatic formulations are indicated with an asterisk in the table below. Buffer distances for both aquatic and non-aquatic formulations are described in the Roseburg IIPM EA, Appendix D.

2. Aminopyralid

Aminopyralid is a growth regulator herbicide that controls annual and perennial broadleaf weeds, certain annual grasses, some woody plant species, and is particularly effective on asters, peas, and certain species in the carrot and knotweed families. Studies have found aminopyralid to be as or more effective at lower application rates than other grown regulator herbicides.

Tank mixing with metsulfuron methyl provides good control for common tansy, knapweeds, and species in the mustard and carrot families. Mixing with triclopyr can broaden the target weed spectrum and provide better long-term control.

7. Glyphosate

Glyphosate is a non-selective branch chain amino acid inhibitor herbicide that targets photosynthetic pathways in the plant. This herbicide is generally used as a spot treatment for broadleaf weeds, woody plants, and invasive annual grasses. This herbicide may also be used to remove nonnative invasive vegetation from campgrounds, parking areas, and other regularly disturbed areas where multiple species of nonnative plants grow together and native species are not present.

Tank mixes of glyphosate and triclopyr are effective on perennial mint species, and tank mixes of glyphosate and imazapyr are effective on perennial grasses.

Some glyphosate products have been developed as aquatic formulations. An aquatic formulation of glyphosate would be used when near standing and running water (including streams, wet ditches, etc.); aquatic formulations are indicated with an asterisk in the table below. Buffer distances for both aquatic and non-aquatic formulations are described in the Roseburg IIPM EA, Appendix D.

The BLM does not use glyphosate formulated with polyoxyethyleneamine (POEA).

8. Imazapic

Imazapic is a broad-spectrum herbicide for broadleaf and grass species but it is particularly effective on invasive annual grasses, and is selective for annual grasses at low rates, leaving perennial herbaceous species unharmed.

Imazapic provides long-term suppression of invasive annual grasses both as a preemergent application (applied in fall or early spring) and in some cases as an emergent application (applied during the growing season to small, rapidly growing plants). Species targeted for control include bristly dogtail, cheatgrass, medusahead, North Africa grass, ripgut brome, and slender wild oats.

Imazapic may be tank mixed with other products that are labeled for the same timing, method of application and site to be treated to broaden the target weed spectrum and provide better long-term control. Active ingredients that could be tank mixed include: 2, 4-D, imazapyr, glyphosate, and dicamba.

9. Imazapyr

Imazapyr is a branch chain amino acid inhibitor herbicide that can be used in aquatic and riparian settings for the control of most annual and perennial grasses and broadleaf weeds. It is very effective on woody species such as brooms, blackberries, hawthorn, and tree of heaven. It can also be used to treat perennial grasses and loosestrife.

Imazapyr may also be used for control of aquatic invasive plants such as parrot’s feather and yellow flag iris.

Imazapyr may be tank mixed with other products that are labeled for the same timing and method of application.

Active ingredients that could be tank mixed include glyphosate and triclopyr.

Some imazapyr products have been developed as aquatic formulations. An aquatic formulation of imazapyr would be used when near standing and running water (including streams, wet ditches, etc.); aquatic formulations are indicated with an asterisk in the table below.

13. Triclopyr

Triclopyr is a growth hormone regulator used for the control of annual and perennial broadleaf weeds and woody plants, such as Himalayan blackberry, purple loosestrife, broom, gorse, and invasive trees. It may also be used on select broadleaf species such as annual peas and buttercups. The aquatic formulations of triclopyr are the most effective herbicide for treatment of purple loosestrife and other aquatic species.

Triclopyr is available as an ester formulation (butoxyethyl ester, referred to as triclopyr BEE) and as a triethylamine salt (triclopyr TEA). Triclopyr BEE is more effective at smaller doses but is more toxic to fish;

only triclopyr TEA formulations can be used in aquatic and riparian habitats. However, triclopyr BEE is often used as a cut-stump treatment.

An aquatic formulation of triclopyr would be used when near standing and running water (including streams, wet ditches, etc.); aquatic formulations are indicated with an asterisk in the table below. Buffer distances for both aquatic and non-aquatic formulations are described in the Roseburg IIPM EA, Appendix D.

Some formulations of triclopyr are effective for cut stump applications on gorse and broom, while others are best for foliar applications. Rates shown in the table below reflect the range of application rates between cut stump treatments (high concentrations) and foliar treatments (low concentrations).

II. PEST: [List specific pest(s) and reason(s) for the proposed application of the pesticide]:

A full list of nonnative invasive species known or suspected to occur on Roseburg District that may be targeted for treatment is listed in Appendix A, Table A-2 of the Roseburg IIPM EA. In addition, invasive species not yet known or suspected on District may be treated under early detection, rapid response protocols.

Noxious weeds and other nonnative invasive plants that are proposed for control projects include, but are not limited to:

• Aquatic species (parrot’s feather, purple loosestrife, yellow flag iris)

• Asters (chicory, common tansy, hairy cat’s ear, oxeye daisy, prickly lettuce, rush skeletonweed, sowthistle, tansy ragwort, wood groundsel)

• Brooms (French, Portuguese [striated], Scotch, and Spanish broom)

• Blackberry species (cut-leaf, European, and Himalayan blackberry)

• Carrots (field hedge parsley, fennel, poison hemlock, Queen Ann’s lace)

• Carnations (bouncingbet, rose champion)

• Geraniums (cutleaf geranium, dovefoot geranium, herb Robert, redstem stork’s bill, shiny geranium)

• Grasses, annual (bristly dogtail, cheatgrass, medusahead, North Africa grass [ventenata], slender wild oats)

• Grasses, perennial (false brome, reed canarygrass, tall fescue, velvetgrass)

• Knapweeds (black, brown, diffuse, meadow, and spotted knapweeds)

• Knotweeds (Japanese, giant, and prostrate knotweed)

• Mints (pennyroyal)

• Miscellaneous forbs (bigleaf periwinkle, bittersweet, butter and eggs, field bindweed, foxglove, Fuller’s teasel, St. John’s wort, woolly mullein)

• Mustards (black mustard, dame’s rocket, jointed charlock, Mediterranean mustard)

• Peas (bird’s-foot trefoil, bur medic, flat pea, perennial pea)

• Starthistles (Maltese starthistle, yellow starthistle, woolly distaff thistle)

• Thistles (blessed milk, bull, Canada, Italian, and slender-flowered thistle)

• Trees and shrubs (common catalpa, common gorse, common pear, eglantine rose, English hawthorn, English holly, spurge laurel, tree of heaven)

• Vines (Atlantic and English ivy)

Infestations would be targeted for treatment in areas where there are vectors for spread (e.g., roads, recreation sites, ROWs, etc.), where infestations put resources at risk (e.g., wildlife habitat, riparian areas, rare plant sites, etc.), or when infestations are small and more easily controllable or the species targeted is known from only a few locations on District. A full discussion of how treatment locations are determined is available in the Roseburg IIPM EA in Appendices A and B.

III. DESIRED RESULTS OF THE APPLICATION – linked to the objectives of the application:

Treatments are intended to control and contain noxious weeds and other invasive plants on the Roseburg District.

These treatments are intended to eliminate seed production, reduce infestation size, and prevent spread of invasive species into non-infested areas on BLM land and neighboring landownership.

IV. APPLICATION SITE DESCRIPTION:

Estimated number of acres: The Roseburg IIPM EA analyzed a range of 500 – 4,000 gross acres treated annually, with an average of 1,500 acres/year. Actual acres treated are dependent on funding and staffing availability.

General description: (Describe land type or use, size, stage of growth of target species, soil characteristics, and any additional information that may be important in describing the area to be treated.)

Treatments would occur throughout the Roseburg District on various land use allocations and in various vegetation community types including, but not limited to, mixed confer forests, oak woodlands, meadows, and riparian areas. Treatments would also occur at recreation sites (day use areas, trails, trailheads, and campgrounds) and along road systems and utility ROWs. Invasive plants would be treated according to Best Management Practices and as described in the Roseburg IIPM EA.

V. SENSITIVE ASPECTS AND PRECAUTIONS: In order to assist in tracking potential impacts associated with Federally threatened, endangered or proposed species, please answer the following questions and then provide the site specific conditions information.

1. Are there special status species (SSS) in the project area? Yes A. If “No” Proceed to the site description portion of this section.

B. If “Yes” Are any of the SSS also federally endangered, threatened, or proposed? Yes

a. If “No” Proceed to the site description portion of this section.

b. If “Yes” Did your Field Office coordinate with the local Fish and Wildlife Service?

Office and/or NMFS? Yes, both I. If “No” Explain (N/A) II. If “Yes” Was Section 7 Consultation Completed? Yes

1. If “No” Explain (N/A)

2. If “Yes” What extent of Section 7 was completed?

Formal and informal consultation.

2b. Describe the outcome of the consultation:

• NMFS Biological Opinion: Aquatic Restoration Biological Opinion II (NMFS Tracking Number: NWP-2013-9664)

• USFWS Letter of Concurrence, 2019 (TAILS Number: 01EOFW00-2019-I-0406), for: Biological Assessment for Activities on the Roseburg District Bureau of Land Management and Umpqua National Forest Affecting the Gray Wolf (USDI 2019)

• USFWS Letter of Concurrence, 2022, and Errata (File Number: 01EOFW00-2022-I- 0044), for: Biological Assessment for Roseburg District Integrated Invasive Plant Management

V. SENSITIVE ASPECTS AND PRECAUTIONS – (CONTINUED): (Describe sensitive areas – marsh, endangered, threatened, candidate, and sensitive species habitat – and distance to application site. List measures to be taken to avoid impact to these areas):

All planned treatment areas are reviewed by the Roseburg District Interdisciplinary Team (IDT) prior to treatment implementation as described in the Roseburg IIPM. In addition to the Project Design Features (PDFs) described in the Roseburg IIPM EA, Appendix D (pp. 104-140), the IDT would develop additional, site-specific PDFs as appropriate to protect sensitive sites.

VI. NON-TARGET VEGETATION (Describe potential immediate and cumulative impacts to non-target pests in project area as a result of the pesticide application. Identify any planned mitigation measures that will be employed – BE GENERAL, SPECIFICS DISCUSSED IN THE EA):

A small amount of overspray can be expected to harm plants adjacent to spot sprayed plants. Treatments will follow the PDFs described in the Roseburg IIPM EA (Appendix D) and the Decision Record for the Roseburg IIPM EA. Additional PDFs may be developed by the IDT during review of the Annual Treatment Plan where potential overspray is not acceptable due to resource conditions or sensitive sites. All treatments will follow BMPs regarding herbicide applications to reduce the likelihood of drift and overspray.

VII. INTEGRATED PEST MANAGEMENT PRACTICES CONSIDERED IN THE OVERALL

PROJECT:

This proposal for herbicide application is just one aspect of the Roseburg District’s integrated invasive plant management program. Prevention measures such as vehicle washing and minimizing soil disturbance are implemented for all projects. Education and outreach programs increase awareness of invasive plant species and methods for how to prevent introduction and spread of invasive plants. Biological control agents for several noxious weed species are already present on Roseburg District and releases of agents not yet on District could be accomplished in partnership with the Oregon Department of Agriculture at appropriate sites. Manual and mechanical control methods are the preferred methods of treatment for some infestations and invasive plant species. Disturbed areas are seeded with native species to reduce risk of noxious weed invasion.

Integrated pest management practices and how they would be applied on Roseburg District are described in the Roseburg IIPM EA, Appendix B.
