Abstract

All standing vegetation with a diameter at breast height ≥10 cm was identified and measured for height, DBH, health and growth status, individually tagged and located within the 1 hectare core plot at the Karawatha Forest node of the South-East Queensland Peri-Urban Supersite (-27.63°, 153.08°). Survey work was undertaken from early February until mid May, 2015. The allometric equation, e was used to estimate biomass (Willliams et al. 2005*) of each tree. This was then corrected for dead trees. That is, trees with S1 growth stage were assigned 90% of the estimated biomass and trees with a S2 or S3 growth stage were assigned 55% of the estimated biomass. *Williams, R.J., Zerihun, A., Montagu, K.D., Hoffman, M., Hutley, L.B. and Chen, X.

Methods and Sampling Information
Methods
Method Step 1
Description
Tree species ID

Identify tree to species level using the “Key to Eucalypts of Greater Brisbane” and “Key to the Wattles of Greater Brisbane”.

Method Step 2
Description
Tag tree and measure x and y coordinates of the subplot

Tag the tree with aluminium tag attached using a nail at a height of 1.6 m. The tag faces the midline of the subplot. X and y, measured in metres to the nearest centimetre was recorded with 0,0 starting from the southwest corner.

Instrument
  • A Laser Technology TruPulse 200 rangefinder and two 20 m tape measures was used to record the position of the tree within the subplot. A 1.6 m long pole was used to locate the placement height of the tag. Round, 3 cm diameter tags with printed numbers were used for identification. Tags were nailed into the tree, with the nail placed at a downward40 degree angle with at least 2 cm between the nail head and the tree trunk left showing.
Method Step 3
Description
Measure DBH, height, health and growth status

DBH was measured at 1.3 m above the ground, with the tape placed perpendicular to the length of the trunk. Height was measured by sighting on a measurable point as close to the apex of the canopy as possible. Health and growth form were allocated based on the AusPlot Forests Survey Protocol Manual v 1.0

Instrument
  • A pole marked at 1.3 m was used with a DBH tape to measure DBH. Tree height was measured using a Laser Technology TruPulse 200 rangefinder
Method Step 4
Description
Estimate biomass

Allometric equation was chosen from Williams et al 2005 (see Abstract). This was then corrected for due to the transformation from logged biomass (LN biomass) to biomass. A further correction was applied to dead trees. Trees with S1 growth stage were assigned 90% of the estimated biomass and trees with a S2 or S3 growth stage were assigned 55% of the estimated biomass.

Sampling
Study Extent Description

The survey was restricted to the 1 ha core plot. The core plot is 100 m x 100 m and is orientated in a north-south and east-west direction.

Sampling Description

All standing trees and live trees on the ground were measured.
