This manual presents standardized methodologies for inventory of Upland Gamebirds in British Columbia at three levels of inventory intensity: presence/not detected (possible), relative abundance, and absolute abundance. The manual was compiled by the Elements Working Group of the Terrestrial Ecosystem Task Force, under the auspices of the Resources Inventory Committee (RIC). The objectives of the working group are to develop inventory methodologies that will lead to the collection of comparable, defensible, and useful inventory and monitoring data for the species component of biodiversity.

This manual is one of the Components of British Columbia's Biodiversity (CBCB) series which present standard protocols designed specifically for group of species with similar inventory requirements. The series includes an introductory manual (Introduction to RIC Wildlife Inventory) which describes the history and objectives of RIC, and outlines the general process of conducting a wildlife inventory according to RIC standards, including selection of inventory intensity, sampling design, sampling techniques, and statistical analysis. The Introduction to RIC Wildlife Inventory manual provides important background information and should be thoroughly reviewed before commencing with a RIC wildlife inventory. RIC standards are also available for animal capture and handling, and radio-telemetry. Field personnel should be thoroughly familiar with these standards before engaging in inventories which involve either of these activities.

Standardized data forms are required for all RIC wildlife inventory. This is important to ensure compatibility with provincial data systems, as all information must eventually be included in the Species Inventory Datasystem. The manuals and data forms are available from:

It is recognized that development of standardized methodologies is necessarily an ongoing process. The CBCB manuals are expected to evolve and improve very quickly over their initial years of use. Field testing is a vital component of this process and feedback is essential. Comments and suggestions can be forwarded to the Elements Working Group by contacting:

The background information and protocols presented in this document are based on the unpublished draft manual, Census methods for upland game birds in British Columbia, prepared for the Inventory Resources Committee by Leslie A. Robb and Michael A. Schroeder. The draft manual was edited to its present form by Ann Eriksson, James Quayle and Leah Westereng. All decisions regarding protocols are the responsibility of the Resources Inventory Committee. Data forms and coding instructions for this manual were developed by Leah Westereng in consultation with the Elements Working Group.
