Compass is a quarterly publication of the USDA Forest Service's Southern Research Station (SRS). As part of the Nation's largest forestry research organization -- USDA Forest Service Research and Development -- SRS serves 13 Southern States and beyond. The Station's 130 scienists work in more than 20 units located across the region at Federal laboratories, universites, and experimental forests.

The Sylamore

The role of fire in the Interior Highlands

Established in 1934, the Sylamore Experimental Forest (Sylamore) is located in the Ozark-St. Francis National Forest in a remote area about 100 miles north of Little Rock, AR. The oldest experimental forest in Arkansas, the Sylamore is also, at 4,180 acres, the largest in Arkansas. The size and remoteness of the site make it an ideal location for future research on woody biomass for biofuels, climate change monitoring, wildlife, and hydrology.

Oak-hickory stands interspersed with pines make up the experimental forest. Shortleaf pines are prevalent on south-facing slopes.

Early research at the Sylamore focused mainly on silviculture with numerous studies that developed and tested practices for managing upland hardwoods. Researchers also performed hydrologic research on local streams and evaluated the effects of timber harvesting on wildlife habitat.

Centuries ago, American Indians in the area frequently used low-intensity fires to clear the land and generate forage. But the frequency of fire in these parts declined along with the number of American Indians after European settlement. Martin Spetich, SRS research forester and manager of the Sylamore, is among the scientists trying to understand the historical role fire played in these forests.

Spetich oversees two keystone studies.One keystone study examines the effect of fire on species dynamics and forest restoration, analyzing both burned and unburned areas in combination with a number of treatments. The other keystone study is being done at the landscape scale using a complex landscape disturbance model to predict future impacts of current management across the Boston Mountains in Arkansas.
