Sustaining Forests

Central Appalachian Forests: Past and Present

Research Issue

[image:] Example of tract data used to create the witness tree database for the Monongahela National Forest.  Tree species noted for this 95-acre tract deeded to Andrew G. Mathews in 1843 came from corners identified in the deed.

Our Research

In the 1930s, the earliest deeds (dates range from 1752 to 1914) for the land within the proclamation boundary of the Monongahela National Forest were plotted on maps and the deeds compiled.  These maps were converted to a digital format, the corners digitized, and tree species referenced in the associated deeds tabulated.  This digital database of tree species at the time of European settlement will be used to describe species-environmental associations and suggest disturbance patterns.  This information can be used to guide forest restoration efforts, not as a static end-point to restore an area to, but as a reference condition to be considered. 

Expected Outcomes

As a result of our research, land managers will make better, more informed decisions about prioritizing ecosystem restoration.  Land managers and others will have a more complete picture of tree species composition before exploitative harvesting about 140 years ago.  Comparison of the early forest to current forests can be used to determine restoration needs or describe trends.
