The Weeden Foundation is committed to protecting biodiversity and supports organizations aligned with this mission.

The Foundation's mission is to protect biodiversity by addressing the adverse impacts of growing human populations and the overuse of natural resources on the planet's biological fabric.

Given the Foundation’s diverse interests and notwithstanding the above, it is sometimes easier to state what is of little interest to the trustees. These include: preservation of what is frequently called the “working landscape”, museums, capital construction, animal rights, growth management, toxic contamination, films and videos, wildlife rehabilitation, government-based projects, faith-based organizations, solid waste, energy (with the exception of dams), universities, student fellowships, and basic scientific research.
