Nanangroe Plantation Plot Network: Bird Point Count Data, Southwest Slopes, NSW, Australia, 2012

The Nanangroe Plantation Plot Network Bird Point Count Data contains counts of all birds seen and heard over five minute periods at each of the 0 m, 100 m and 200 m posts along a permanent 200m transect at each site. Dawn bird counts are conducted every 1-2 years using repeated point interval counts. Repeated point counts by two different observers on two different days are undertaken. The distance that each bird was seen/heard at is recorded along with bird abundance and any anecdotal comments (e.g. breeding behaviour). Bird species presence/absence or detection rates within 50 m of the observer is commonly used for analysis. The principle objective of the Nanangroe study is to directly quantify changes in woodland vertebrate assemblages and their relationships with habitat variables when the surrounding landscape matrix is converted from a semi-cleared grazing landscape to a landscape dominated by an exotic softwood plantation (Lindenmayer, DB, Cunningham, RB, MacGregor, C, Tribolet, C & Donnelly, CF 2001, ‘A prospective longitudinal study of landscape matrix effects on fauna in woodland remnants: experimental design and baseline data’, Biological Conservation, vol 101 no 2, p. 160). The study area is located in the Southwest slopes of NSW west of Lake Burrinjuck and includes four exotic Pine Plantations (Nanangroe, Cotway, East Bungongo and Bungongo), as well as private properties adjacent those plantations. Repeated sampling of the vegetation structure and cover and selected vertebrate groups on all sites from 1998 has created a long term dataset.
