Karawatha Peri-Urban, Abundance Of Hollow Bearing Trees Data, 2009 

The dataset contains information on the abundance of hollow bearing trees in the Karawatha Peri-Urban site recorded from between 2006 and 2009. There is information on the tree species name, diameter at breast height, tree alive status, and a number of attributes related to the hollows, such as its location, height, length, width and the type. 

We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging. 

Data not provided. 

The abundance of hollow bearing trees (>30 cm DBH) was measured on 33 1-ha PPBio plots at Karawatha Forest Park. Tree and hollow attributes were measured for each hollow bearing tree (HBT) that were detected during these surveys. Plots were spaced at 500 m intervals, followed the elevation contour and each plot was 250 m long and 40 m wide. Tree and hollow characteristics were also measured. Surveys occurred between June and August 2009. Sampling occurred on all 33 PPBio plots within Karawatha Forest Park. Taged trees (>30 cm DBH) within 20 m each side of the 250 m long transect were surveyd for hollows.
The Tree form based on: Lindenmayer, D. B., Cunningham, R. B., Donnelly, C. F., Tanton, M. T., and Nix, H. A. (1993) The abundance and development of cavities in Eucalyptus trees: a case study in the montane forests of Victoria, southeastern Australia. Forest Ecology and Management 60, 77-104.
