Description
The reference state includes one major NatureServe ecological systems as described previously, Southern Appalachian Oak Forest. Oaks now dominate this site where American chestnut once would have been a major species dominant in the canopy. Invasive, non-native forest pests and pathogens such as American chestnut blight, dogwood anthracnose, and European gypsy moth (among others) are really the greatest threat to this PES. Most of it is still currently forested, although a good bit of it has been logged, burned or both in the past. Pine communities may be an important component of this PES and future investigations should explore that as well as the role of fire and past disturbance on currently established vegetation communities.
Description
Practically all this site is in forest so, nearly all relevant management consists of forestry practices. Some small acreage is in pasture and hay but that is very small in extent. Further investigation in the field is needed as future projects are identified to refine this PES into what will most likely become multiple ecological sites. Fire may be an important forestry management tool but that should be confirmed through further research.
Description
Perhaps the greatest challenge to the integrity of this ecological site is the presence of invasive, non-native pests and pathogens. The impact and response varies by species (both of the host and the invader) but often will include combinations of mechanical, biological, chemical and cultural control. Tree breeding programs for genetic resistance and germplasm conservation may be important considerations, especially in front an incoming invasion if reforestation is planned after it passes. It is always best if local genetic material can be used if restoration efforts are attempted.
Mechanism
Abandonment (~100 years until reversion to forest); control of non-native plants and pests where needed
