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.

How to Donate Stock

Each stock gift we handle strengthens our programmatic work while providing tax benefits for supporters.

Here are step-by-step instructions to help you take advantage of this gift planning opportunity:

Give your broker the following information to transfer a gift of stock to the Sonoma Ecology Center:

  1. The Sonoma Ecology Center’s brokerage account is with Charles Schwab Co. Inc.
  2. The Sonoma Ecology Center’s account number is 5655-2785.

Either you or your broker must contact us via email or call 707-996-0712 ext with the name of the stock and the number of shares being transferred. This ensures the gift is properly credited and acknowledged.

When SEC receives a stock gift, our policy is to sell the stock as near as possible to the date of the gift.

The Impact of the October 2017 Fires

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.

Thanks to our dedicated volunteers and supporters, one year after the Tubbs fire, the last section of Sugarloaf has been repaired and reopened to the public.

Below, video footage recorded by one of the wildlife cameras set up at Sugarloaf Ridge State Park that documents the progression of the fire.
