This list compiles observations of Dusky-footed woodrat species in the area by counting their characteristic nests. The following data will contribute to conservation efforts and help track changes in woodrat populations due to habitat loss, climate change, and other environmental factors.

We seek to make sure that action in the El Cerrito Hillside Natural Area meet environmental requirements for protection of special-status species. This will be of immediate concern as the city presumably seeks to submit a mitigated negative declaration of environmental impact, and of long-term concern to make sure that actions and their effects are evaluated as work to reduce fire hazard goes on.

We also want to record the surrounding habitat to understand the types of areas where they like to build and, thus, what areas management should avoid or protect. Counting the number and characteristics of nests shows that woodrats live in the HNA and are a keystone species in the ecosystem. Their ecosystem services include:
· Biodiversity: Nests provide habitats for various other species like insects, small mammals and reptiles;
· Seed dispersal: nests aid in seed dispersal since rats collect and store seeds, and unconsumed seeds germinate and contribute to plant diversity and forest regeneration
· Soil enrichment: decomposition of materials within nests enriches the soil and adds nutrients to the soil, promoting plant growth and the overall health of the ecosystem.
