Purpose: to identify avian communities associated with forested habitats in the Liard River Valley. to identify specialist species which exhibit restricted habitat use and are therefore most threatened by alterations to the natural landscape. Description: We used fixed-radius point counts (75 metre radius) to survey breeding bird communities in six different forested habitats as well as cutblocks in the Liard River Valley, Yukon. We established 147 census points in the seven habitat types. Census points were established along transects and were at least 150 metres apart and at least 75 metres from the nearest edge or major habitat break. We used 10-minute point counts during which the observer stood at the point and recorded all birds detected by sight or sound within 75 metres. All counts were conducted by C. Eckert and P. Sinclair between 5:00 am. and 9:30 am., and each point was visited twice between 29 May and 29 June 1994. The two observers were switched between points for the second set of counts to control for observer bias. More details are available in the metadata document for download. CWS-North DatasetID: 063_0
