Vertical vegetation profiles of 33 one-hectare plots in Karawatha Forest Park. The plots are at 500 m intervals in a grid that covers the entire Park. Each plot follows the elevational contour and is 250 m long x 40 m wide. For each plot, the density of stems within 10 height classes was estimated from counts taken at 10 m intervals along the length (250 m) of the plot. Measurements were taken during the period August 2007 to January 2008.
Determination of vertical vegetation profile
Vertical vegetation profiles were determined at each of 33 plots using the methods outlined by Condit (1998). Vegetation transects were completed along the entire 250m plot length, 10m to the right of each plot midline. At 10m intervals a 5m telescopic pole was vertically erected to determine the presence or absence of vegetation within ten height classes. Below 5m the presence or absence of vegetation was determined at 1m intervals, while intervals of 5-10m, 10-15m, 15-20m, 20-30m and >30m were assessed visually above the 5m stratum. Within each stratum the 26 estimates were averaged to obtain a single value for each plot (i.e. one value per stratum). (EcoAccess Permit Number – WISP05347908).Reference:Condit, R. 1998.
