Reas Run Research Natural Area
The principal feature of the RNA is a series of mature stands of Virginia pine (Pinus virginiana). The pines originated naturally following abandonment of agricultural land in the approximate period 1915-1920. Succession to hardwoods is well underway with red maple (Acer rubrum) generally dominating the sapling stratum. The hardwood stand is without exceptional qualities, but it does provide a buffer zone for the mature pines and could provide useful information on tension zone relationships between the two types.
Physical and Climatic Conditions
- Nearest weather station, with distance and direction from RNA:
- The closest station is at Parkersburg, WV, 20 miles (32.2 km) from the RNA.
- Annual precipitation (type, seasonal distribution) :
- Average annual precipitation is 39 inches (99.06 cm).
- Maximum and minimum temperatures:
- Minimum average January temperature is 24 °F, and the mean maximum July temperature is 88 °F.
- Elevation varies from approximately 800-1200 feet (261.6-392.4 m).
- Geology and Soils:
- Local topography consists of low, but fairly steep ridges and hills. Predominant soils are Upshur silty clay loams. Bedrock is shale and resistant sandstone. The area has not been glaciated.
- Aquatic Features:
- Reas Run is an intermittent stream within the RNA that flows into the Ohio River.
