The 2015 Season: Putting Nature First

Martin Griffin Preserve Temporarily Closed to the Public

ACR is committed to protecting the natural resources of its properties using science-based management. In an effort to promote reestablishment of the heron and egret nesting colony that was abandoned by the birds after 60 years, ACR will continue closure of the Martin Griffin Preserve to the public during the 2015 nesting season.

ACR’s Education Programs for students continue in the preserve's Volunteer Canyon, with no interruption to nature-based learning.

ACR offices remain open during this time.
