About the Project
The new Nature Center will host an array of public programs, a series of permanent exhibits and interpretive experiences, plus it will be a beautiful example of sustainable design techniques including solar power, water conservation and recycling, waste reduction and straw bale insulation!
The new Nature Center will feature straw bale insulated walls using the hybrid Straw-Cel method. With plywood and cellulose insulation between the studs on the exterior face, straw bales (sourced from The Nature Conservancy’s Staten Island Farm in the Sacramento-San Joaquin River Delta) are stacked inboard of the wall for an R Value of 43 (indicates thermal performance), which is excellent for the harsh winters of Sierra Valley.
On September 30th, the Feather River Land Trust is looking for volunteers to help with the installation of the straw bale insultation. Anyone can help—from positioning bales, cutting bales, to sweeping floors—we have a job for you! And you’ll be part of a very special moment in the construction of the SVP Nature Center and leave your mark in the walls of the Preserve. Plus, you’ll learn about straw bale construction from some of the leaders in the field.
Questions? Contact Jenna Holland, Public Programs Manager at jholland@frlt.org.

We look forward to seeing you on the preserve!
