Abstract: Fact: Tree mortality at small spatial scales represents background levels of forest disturbance in the southern Appalachians, and is the dominant and most frequent initiator of change in terrestrial ecosystems.

Hypothesis: Large-scale and rare episodic events (i.e., hurricanes, ice, etc.) may do more to influence tree replacement and stand composition in the long-run than do small scale tree mortality events.

Overall Question: What is the ecological significance of small scale mortality events with respect to biotic and abiotic responses?

Methods/Experimental Design: Approach: Experimentally create typical (<300 m2) canopy gaps (girdling and herbicides) at two elevations in Rhododendron and non-Rhododendron areas.

Measurements:
-automated micro-environmental measurements (air and soil temperature), photosynthetically active radiation, %WC.
-hemispherical photography
-dendrometer bands and repeated measurements
-population dynamics and seedling physiology
-in situ closed core N-mineralization and nitrification
-small and large mammal seed and plant herbivory using exclosures.

DBH trees banded with dendrometer bands.
set = 0 = date tree were initially banded.
Initial DBH in centimeters.
Subsequent readings in inches-circumference.
