Overview
The Weeden Foundation was established by Frank Weeden to address the impact of human population growth and overuse of natural resources on the planet's biological systems. Since 1984, the Foundation has helped preserve over 6 million acres of biologically important habitat worldwide and provided financing for the first debt-for-nature swap in Bolivia in 1992. The Foundation embraces the protection of biodiversity as its overarching priority, with approximately $1.7 million distributed annually across 138 grants. In 2019, the Foundation received a major estate bequest from trustee John (Jack) D. Weeden. In 2015, the Foundation co-founded the Quick Response Fund for Nature in partnership with 1% for the Planet and RESOLVE to support urgent habitat acquisition opportunities.

Application Process & Timeline
How to Apply
New Applicants:
- Submit a Letter of Inquiry (LOI) through the "New Applicants" form at grantinterface.com
- LOI must be submitted at least 4 weeks before the proposal deadline
- Receive confirmation email when form is complete
- Foundation reviews and responds - if work fits program areas, they invite a full proposal
- Submit full proposal if invited
Returning Grantees (organizations that received a grant the previous year):
- Do not need to submit an LOI
- Complete "Returning Grantees" application directly
- Include project purpose, brief evaluation process, Executive Summary, financial statements, Board of Directors list, IRS tax exemption documentation, and project/organizational budgets
Quick Response Fund for Nature:
- Email info@weedenfoundation.org to learn about the application process
- Applications accepted on rolling basis throughout the year
Application Deadlines
Board meetings occur the last Saturday in February, June, and October. Specific proposal deadlines are posted on the website (e.g., May 15th deadline for June board meeting). Letters of Inquiry must be submitted 4 weeks before the proposal deadline.
Eligibility Requirements
- Must be a 501(c)(3) organization or international equivalent
- No multi-year grants
Decision Timeline
Decisions are made at board meetings in late February, June, and October. The Foundation reviews LOIs and responds to applicants about whether to invite full proposals. Specific notification timelines are not publicly disclosed, but the LOI-to-deadline structure provides approximately 4 weeks of lead time for invited proposals.
For the Quick Response Fund for Nature, the team strives to make decisions within a timeline commensurate with the needs of the applicant.
Success Rates
Specific success rate data is not publicly available. The Foundation awarded 138 grants in 2024 from an undisclosed number of applications.
Reapplication Policy
Specific reapplication policies for unsuccessful applicants are not publicly disclosed. The Foundation distinguishes between "new applicants" and "returning grantees" (those funded the previous year), but does not clarify policies for organizations that applied unsuccessfully. Organizations should contact the Foundation directly for guidance.
Application Success Factors
Emphasize Shorter Descriptions: The Foundation explicitly states that "shorter descriptions are preferred to longer descriptions." Be concise and direct in all application materials.
Executive Summary is Critical: The Foundation notes that "the Executive Summary is especially important as it is the best vehicle for an organization to present the nature and intent of their project directly to the Board of Directors." This section should be crafted with particular care.
Clear Purpose and Evaluation: Proposals must "describe both the purpose for which the grant is solicited and a brief evaluation process in a clear and precise manner." Don't overlook the evaluation component.
Geographic and Thematic Alignment: The Foundation has very specific geographic focus areas (Alaska, Northern California, SW Montana, Chilean Patagonia) and thematic priorities (birds, marine wildlife, sustainable consumption, population). Projects must fit clearly within these defined areas.
Biodiversity Protection First: All programs roll up to the Foundation's overarching priority of protecting biodiversity. Applications should explicitly connect their work to biodiversity outcomes.
Strategic Conservation Approach: The Foundation supports work that is strategic and systemic - habitat acquisition, policy change, corridor protection, institutional capacity building - rather than basic research or rehabilitation.
Consider the Quick Response Fund: For time-sensitive habitat acquisition opportunities, the Quick Response Fund for Nature offers faster decision-making on a rolling basis and can provide grants up to $50,000.
Key Takeaways for Grant Writers
- Keep it concise: The Foundation explicitly prefers shorter descriptions and values brevity in applications
- Perfect the Executive Summary: This section goes directly to the Board and is your best opportunity to make your case
- Know your geographic fit: The Foundation has four specific geographic areas (Alaska Tongass, Northern California Klamath-Siskiyou, Montana High Divide, Chilean Patagonia) - if your work isn't in these regions, it needs to fit a thematic program like bird conservation or sustainable consumption
- Plan for the LOI step: New applicants must submit a Letter of Inquiry 4 weeks before the deadline - factor this into your planning and don't expect to submit a full proposal on first contact
- Align with biodiversity: Everything the Foundation does ladders up to biodiversity protection - make this connection explicit in your proposal
- Realistic grant expectations: Standard grants are $10,000-$30,000 (not larger) and there are no multi-year grants, so plan your budget and timeline accordingly
- Consider timing options: Standard grants follow a fixed schedule with three board meetings per year, but the Quick Response Fund offers rolling applications for urgent habitat acquisition needs
