This year those age 70 ½ and older may want to consider making a meaningful, tax-efficient gift to Sonoma Ecology Center using funds from their traditional or Roth IRA. With this way of giving you can:

  • Make tax-free gifts each year from your IRA withdrawals by having a portion transferred directly to SEC (up to $100,000 per year for an individual; $200,000 per couple with separate IRAs).
  • Use your Required Minimum Distribution for you gift to avoid taxes on the transfer of funds.
  • Avoid increasing your adjusted gross income and potentially subjecting your Social Security income to a higher level of taxation by giving directly from your IRA.
  • Provide a generous gift to SEC.

Please contact  if we can provide more information to you or your advisors.

Support Sugarloaf Ridge State Park

About 75% to 80% of the park burned in the October 2017 Tubbs fire. Some of the fires were slow underbrush fires and others were much hotter and damaged trees and soil. Most of the buildings the park survived. Robert Ferguson Observatory, the Visitor Center, main campground bathrooms, white barn, and red barn all were undamaged. We did lose two of 6 toilets in the campground, one water tank, and the meadow trail bridge.  

The park’s trails and trail infrastructure (footbridges, retaining walls, steps) suffered well over $80,000 of damage. To fully open the park we need your help!  

Together we are the caretakers of this incredible Sonoma County gem. Please support Team Sugarloaf and help us maintain and fully reopen Sugarloaf Ridge State Park for everyone!

Your membership or donation supports park operations, including projects to maintain Sugarloaf’s beauty, accessibility, and park amenities. 

More than just a park, Sugarloaf Ridge allows visitors to appreciate the tremendous beauty of the North Bay — and, through the Robert Ferguson Observatory, the universe!

Sustaining your park requires a team effort. Please help to share the responsibility for caring for this special place by becoming a member, or making a gift today! Your contribution provides the funding needed to ensure Sugarloaf Ridge State Park can flourish today, tomorrow and well into the future!
