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 a threat to this PES. Reference conditions still exist on this site but much of it has also been converted to agriculture or urbanized.
Description
Pasture and hay are very important and common land-uses on this site. In addition, some crops are grown including corn, burley tobacco, small grains and vegetable crops.
Description
Where reference conditions still exist, non-native forest pests pose a threat. Where pasture or crops exist, non-native plant species and weedy natives can become problematic. 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
