Consequences of Fire and Fire Surrogate Treatments: The Central Appalachian Plateau Site - Animations and Videos - REMA
Racoon Ecological Management Area
About the Fire
Location: Raccoon Ecological Management Area, Ohio
Date of burn: April 5, 2001
Forest Type: Oak-Hickory
Forest Relief: Rugged/Hilly with fairly steep slopes
Note: The site layout did not allow the burning of both units together. The thin and burn unit was burned first followed by the burn only unit.
The unit was fired using three firing teams, two working along the north and south edges of the unit, one firing through the center of the unit. Each firing team used two or three drip torches allowing them to light several lines of fire parallel to the control lines.

About the Animation
- The animation is based on "real" temperatures recorded on HOBO recorders from 121 thermocouple locations in Raccoon Ecological Management Area.
- The actual temperature data were recorded at 2 sec intervals from 25 cm above the ground surface. These data were sliced into 343 time slices corresponding to 30 sec intervals.
- However, the actual time-step in the animation is at 2.5 minute time intervals (The "Tsxx" in the animation) to reduce loading time.
- The temperatures were interpolated using inverse weighted distance using 2 points in the search radius.
- The maps were created with ArcView 3.2a Avenue script.
- As the area gets burned (ie., "affected" by the burn since the area burned is dependent on the accuracy of the interpolation), the color changes from lightbrown to gray.
- The color scheme is self-explanatory, with the brighter reds indicating hotter burns.
- The statistics for the temperature (in deg C) across all 126 points are:
|1st Qu.||Median||Mean||3rd Qu.||Std.Dev|
- Earlier studies have shown that temperatures above 150 deg C will topkill most saplings (< 10 cm diameter). See the legend below:
