Effects of Edge Orientation and Internal Fragmentation on Cyclone Disturbance Patterns in Mabi 5b Fragments Jeffrey Allenby School for Field Studies Center for Rainforest Studies Queensland, Australia Faculty Advisor: Amanda Freeman
Took visual assessments on a 50m grid using the Curran Scale at 564 sites
Level Description 0 No Disturbance-Canopy is still largely intact and mostly closed 1 Light Disturbance-No tree fall or stems snapped in the canopy. Canopy predominantly still intact with <25% loss 2 Moderate Disturbance-Canopy foliage retention is 25-50%. Larger limbs will be lost and fallen along with an occasional tree fall in the canopy. 3 Heavy Disturbance-Widespread defoliation of canopy and 50% canopy foliage removed. Extensive treefall or trunks have been snapped off.
