Statement of Work

Bureau of Indian Affairs Noxious Weed Program

1. INTRODUCTION

A. Context of Weed Management

The Chickasaw Agency (Agency) has the responsibility to manage approximately 74,000 acres of trust and restricted properties for the Chickasaw Nation and individual members of the Five Civilized Tribes within the Chickasaw Nation. The agency has developed a Noxious Weed Control Program to assist with the management of pasture and range conditions. The purpose of this program is to prevent the introduction and spread of noxious weeds on trust and restricted lands under the management of the Chickasaw Agency. Through the agency’s Noxious Weed Control Program, weed control is accomplished and the productivity and value of each tract is increased and maintained.

There has been a massive expansion of invasive plant species across the United States, including Indian Country and the Chickasaw Nation. New problem species arrive every year. These plants create large economic losses for agriculture in rangeland situations. Noxious weeds often provide poorer habitat for wildlife than native vegetation. Expansion of these noxious weeds alters ecosystem processes and decreases certain native species or threatens local extinction. Unchecked, these weeds threaten our economic livelihood and our biological heritage.

In recognition of the economic and ecological impacts of noxious weeds, the State of Oklahoma passed The Oklahoma Noxious Weed Law that declares musk, Scotch, and Canada thistle to be noxious weeds and a public nuisance. The law also requires landowners and managers to control these noxious weeds on their properties. Failure to do so can result in a fine being assessed.

B. Overview of Approach to Weed Management

Noxious weed control is an integral aspect of property management. The Chickasaw Agency Noxious Weed Management Plan is based on the management and preservation of desired plant species and communities, rather than on simply eliminating weeds. The plan is intended to restore and maintain rangeland and native landscapes in productive condition, ensuring economic and ecologic sustainability.

Preventive programs are implemented to keep the management area free of species that are not yet established, but which are known to exist elsewhere in the area. Priorities are set to reduce or eradicate established weeds on the property. Prioritization criteria include actual and potential impact on land management goal as well as the short- and long-term effect required for control. Action will be taken when careful consideration indicates control measures are necessary.

This plan follows the adaptive management approach. First, weed species are identified through inventory of the property. Second, land management goals and weed management objectives are established for the property. Third, priorities are assigned to the weed species and infestations based on the severity of their impacts, while considering the ability to control them. Fourth, control methods and the resulting impacts of control methods are evaluated to determine overall sustainability of the management practice.

Fifth, Integrated Weed Management (IWM) plans are developed based on this information. Sixth, the

IWM plans are implemented. Seventh, the results of management actions are monitored and evaluated in light of weed management objectives for the management area. Finally, this information is used to modify and improve weed management objectives, control strategies, and subsequent IWM plans. It is intended that a structured, logical approach to weed management, based on the best available information, is more feasible, effective, and sustainable than an approach that addresses specific noxious weed issues after they become a concern.

2. LAND CLASS / DESCRIPTION OF THE PROPERTY (or management area)

A. Boundaries

The Chickasaw Agency’s jurisdiction includes approximately 74,000 acres of trust and restricted properties of the Chickasaw Nation and individual members of the Five Civilized Tribes within the Chickasaw Nation.

The properties consist of scattered tracts located within 13 counties in Southern Oklahoma. Adjacent properties or properties located in the immediate vicinity are managed as one common weed management area, regardless of ownership, in an effort to consolidate weed management activities and obtain long-term weed control. (See image below)

B. Resource Base

The managed lands consist primarily of agricultural rangeland used predominantly for livestock grazing and forage production. Forages consist of native forages and improved introduced forages. Areas of cultivated cropland exist on some tracts used primarily for small grain and winter forage production. A limited amount of commercial forest land is present within the jurisdiction of the Chickasaw Agency.

Income from properties is derived from agricultural production, as well as oil and gas production. Areas of concern for noxious weed control are mainly limited to agricultural rangeland used for grazing and forage production.

3. INVENTORY OF WEED SPECIES

A. Inventory of Weed Species

Inventories are performed twice annually during lease compliance checks by agency personnel. Noxious weeds are identified during the inspections and severity is categorized according to Oklahoma State Department of Agriculture Regulations.

(1) Light infestation Less than two (2) plants per acre.

(2) Medium infestation Two (2) to nine (9) plants per acre.

(3) Severe infestation Ten (10) or more plants per acre.

4. MANAGEMENT GOALS AND WEED MANAGEMENT OBJECTIVES FOR THE PROPERTY

A. Land Management Goals

The Chickasaw Agency’s primary goal is to preserve and increase the value of the natural and financial resources under its management. By effectively controlling noxious weed infestations within the Agency’s jurisdiction properties are maintained at their optimal condition. Productivity of the properties is greatly improved with proper noxious weed management, resulting in increased economic return. By decreasing competition from noxious weeds, desirable species are maintained and increased benefiting both livestock and wildlife through increased forage production.

B. Weed Management Objectives

The Chickasaw Agency’s weed management objective is to keep noxious weed infestations below the economic threshold. Current infestations must be considered, as well as potential infestations that will result if noxious weeds go untreated. The economic threshold for the weed population occurs at the point at which cost of control is equal to value of yield attributable to that control, or the value of the yield loss associated with the weed infestation equals cost of the control.

Description: The Chickasaw Agency (Agency) has a requirement for noxious weed treatment on BIA restricted land within specific areas of the Chickasaw Nation. The project site consists of approximately 1966-acres located in the counties of Garvin, Grady, Johnston, McClain, Marshall, Love, and Stephens within the Chickasaw Nation boundary. For this project, the Musk thistle is the highest priority species that needs to be treated.

The goal is 90% kill for each listed tract so that, in combination with other ongoing weed control efforts, these species will eventually be eradicated from BIA-Chickasaw Agency administered lands within the Chickasaw Nation.

PERIOD OF PERFORMANCE: Work shall be performed from approximately March 1, 2026, through April 30, 2026.

The Contractor Will:

Include a General Work Plan that contains the following:

o Schedule for completing work o General description of operating procedures o Methods to ensure thorough coverage of the contract area o Methods of application, i.e. type of equipment to be used in various situations

APPENDIX 1

STANDARD OPERATING PROCEDURES AND HERBICIDE APPLICATION

SAFETY, EQUIPMENT & APPLICATION

The safety of the general public will be a primary consideration when conducting treatments.

Contractor will provide sufficient clean water to assure the opportunity for workers to wash off any chemicals splashed inadvertently onto skin or in the eyes.

All personnel involved in pesticide application must be trained and licensed. Protective clothing and equipment, as specified on EPA approved labels and the National Pesticide Applicator Certification Core Study Manual (i.e., coveralls, unlined rubber gloves and boots, safety glasses, hard hat, respirator, as appropriate) will be worn by workers directly involved in herbicide applications and by employees using hazardous tools/equipment. The applicator must have and maintain an Oklahoma Pesticide license or be trained in the use of herbicide application and working under the direction of a licensed applicator. All personnel handling pesticides will read the Safety Data Sheet and the label for each product prior to handling or applying the pesticide.

While mixing and loading, the individuals will wear appropriate protective gear as specified on the chemical label (examples--- full length apron, face shield, unlined rubber gloves, liquid repellant footwear).

Spray pressures will meet label and nozzle tip requirements. All equipment shall be properly calibrated before applications are made and to prevent gross errors in the field while mixing.

Regular testing on field calibration and calculation will take place (once a month during use or more often if used frequently.)

Spray nozzles must be set to produce spray droplets with a median diameter of 200 microns or larger unless the product label specifies. If ground vehicle equipment is used, they will be operated normally with a boom pressure of 20 to 35 pounds per square inch, unless the product label specifies a different pressure.

Herbicides will be mixed and loaded in an area where an accidental spill cannot flow into a stream, water body, or contaminate groundwater. No mixing is allowed in riparian areas. Applicators are required to have an emergency spill kit to mitigate small spills. Spills of any size will be reported to the BIA.

Wind velocity must be 8 mph or less, except in riparian areas where the wind speed must be 5 mph or less unless the label states differently. Do not spray when wind is less than 1 mph and no spraying when heat index in greater than 90 degrees Fahrenheit.

Equipment shall be cleaned only in specifically designated areas away from waterways and reservoirs, wells and stock tanks. All containers shall be triple rinsed and reinstate used in the spray tank. Containers will be disposed of at a state collection site for recycling, an approved landfill or other specifically designated areas according to Federal, State and Tribal laws.

The licensed applicator will provide copies of pesticide application records for each application site, recording the date of application, start time, finish time, amount of herbicide, surfactant, and dye applied, application rate, type of equipment used, weather, location, pest treated, and acres treated. Records will be completed within 24 hours of application and submitted biweekly or upon the request of the BIA. This record will be maintained in the BIA project file.

TREATMENT

Treatments will be conducted in accordance with applicable Federal, State and Tribal government regulations, including the Sikes Act (16 U.S.C. 670 eL seq.), as amended, the Federal Land Policy and Management Act (http://www.blm.gov/flpma/), the Federal Noxious Weed Control Act (http://ipl.unm.edu/cwl/fedbook/fedweed.html) as amended in Section 15 of Public Law 93-629. These laws and policy provide direction for BIA to coordinate with appropriate State, Tribal and County entities and those related weed control agencies and to operate in harmony with State and County entities and those related weed control agencies and to operate in harmony with State.

Hand pulling and using hand tools to remove noxious weeds may be used when no other means are available to control or eradicate the targeted noxious weed. This method may be effective on new infestations. Gloves and protective clothing will be worn.

Ordinarily, several considerations govern the choice of treatment method. The choice first depends upon the species of noxious weed. Treatment objective, topography of the treatment area, expected costs, and equipment limitations are implied considerations. Another consideration is the selectivity of the herbicides.

Commercial products for noxious weed treatment will only be used if the noxious weeds are susceptible to the herbicide, i.e., that is with one treatment the herbicide will retard 90 percent of current years’ growth of the target noxious weed. In large dense stands, 90 percent control may not be realistic the first year.

Effort should be made to reduce adverse effects of spraying on several non-target woody plant species (Oak, Pinon pine, Juniper). These species are important for wildlife habitat, soil stability and visual resources.
