Program description
The Office of Insular Affairs (OIA) is requesting funding proposals for its Brown Treesnake (BTS) Control Program to prevent the migration of the BTS from Guam to other United States jurisdictions; to suppress and control the BTS on Guam to support the restoration of the island’s native ecosystems; to avoid electrical outages to civilian or military facilities caused by the snakes; and to ultimately develop the capability to eradicate the BTS from Guam.The Administration will prioritize projects that drive economic growth, ensure reliable and affordable energy, and strengthen national security and regional stability.

FAQ
Who is eligible to apply for the OIA Brown Treesnake Program grant?
Typical eligible applicants include nonprofit organizations, universities, research institutions, tribal nations, federal agencies, and state/local governments working on invasive species management, particularly brown treesnake control and research.
What is the application deadline?
The application deadline is June 8, 2026. Applications open on March 16, 2026, providing approximately 12 weeks for preparation and submission.
What types of activities and projects does this grant support?
The program supports research on brown treesnake biology and control methods, development of innovative detection and removal technologies, prevention strategies for non-infested areas, public education and outreach, and on-the-ground management implementation in affected regions like Guam.
How competitive is this grant program?
Brown treesnake-focused funding is typically competitive, as there are a limited number of eligible organizations with expertise in this specialized invasive species issue. Strong applications demonstrate clear understanding of BTS ecology and documented results or capacity to achieve measurable outcomes.
What is the typical funding range for awards?
Funding amounts vary based on project scope and agency priorities. Applications should request amounts justified by the project scope and timeline. Past awards for similar DOI invasive species programs typically range from $50,000 to several hundred thousand dollars, depending on project scale.
💡 Tips for applicants
- Target your project narrative to the specific brown treesnake challenge: whether addressing Guam impacts, prevention in other Pacific territories, or broader invasive species science that applies to BTS control. Specificity about geography and species problem strengthens applications.
- Demonstrate capacity and expertise: include team member bios, prior publications on invasive species or BTS specifically, letters of support from partner agencies (USDA, Guam Department of Agriculture, etc.), and evidence of institutional commitment to the work.
- Show measurable outcomes: propose clear metrics for success (e.g., snakes detected/removed per unit area, acres protected, number of communities trained). Agencies fund projects with demonstrated potential for tangible impact.
- Address both on-the-ground work and knowledge sharing: proposals combining direct management activities with research dissemination, training, or technology transfer are more competitive than single-focus projects.
- Build collaborative partnerships: engage relevant stakeholders such as USDA Wildlife Services, University of Guam, local communities, or other federal agencies. Coordination strengthens likelihood of sustained impact and demonstrates broad support.
⚠️ Common mistakes
Applications often fail by proposing research without clear connection to on-the-ground brown treesnake management or by lacking demonstrated expertise in invasive species control. Weak applications frequently underestimate the specialized knowledge required for BTS work or fail to address how results will be implemented or scaled beyond the grant period.
