Sampling for E013

Trees: Trees were sampled in transects 10m x 50m. Within these transects the center of each tree and sapling was located (x, y coordinates). The position, diameter at breast height (dbh), damage category, and any other supplementary information was recorded. Trees and shrubs were drawn and numbered on the map.

Damage categories are:

1. undamaged
2. tip-up: record approx. angle with ground and direction of fall
3. snap: record estimated height at which center of tree was snapped and whether the trunk was rotten or free of rot at the point of the snap
4. bent: record angle of the tree top
5. other tree fell on it: record # of other tree
6. none of the above: explain damage succinctly
D. probably dead before storm-also include one of the number categories listed above

Tip-ups: For each tip-up, the location was drawn on the map and the greatest height above ground level (highest dirt, not roots) and length (perpendicular to the trunk) were recorded.

Ground Cover: The transects were divided into 10 x 10m quadrats. Inside each quadrat, a 1 x 1m plot was located using a pair of numbers from the list of random x, y coordinates. The random x, y coordinates were used to locate the corner of the plot closest to 0, 0. If the plot fell under a trunk (standing or fallen) the next set of random x, y coordinates are usee instead. Any pair of random x, y coordinates was used only once. All species present within the 1m x 1m plot were recorded. Four 1m x 1m ground cover plots were done in each 10m x 10m quadrat.
