Systematic sampling procedures are used to estimate the distribution and relative abundance of plants and vertebrates. Line and point transects, in conjunction with the Daubenmire frame method are used for sampling vegetation cover, composition and density. Live trapping for small mammals and drift fence arrays for reptiles and amphibians are used to record occurrence and estimate relative abundance. Point counts, belt transects and mist netting for nongame birds are used to develop checklists and monitor long term trends in bird populations. Mist nets are also used to sample bat populations.
All data collection is conducted seasonally.
A procedures manual has been produced, and field training of various survey techniques is ongoing. Data collected from these procedures will be used to assess long-term trends in habitat and nongame species, evaluate the effectiveness of various habitat management techniques, and incorporate data for nongame species into a statewide Terrestrial Wildlife Database.
