- To provide an in depth evaluation of the impact of BBD on the Tionesta, old growth, beech-hemlock forest type by re-measuring part of the long established Zimmermann grid of plots. The data will be of dual use for it will be used in an assessment of the BBD module of the FVS model being developed by Jones et al. (The Forest Vegetation Simulator (FVS) is the USDA Forest Service's nationally supported framework for forest growth and yield modeling.)
- To document, and seek an explanation for, beech mortality levels detected in off plot observations that far exceed expectations derived from an existing dispersed grid of FHM and FIA plots on the ANF.
- Uses the documented impact of Beech Bark Disease on unmanaged old-growth stands of the beech-hemlock forest type as an indicator of potential long term outcomes in areas where management promotes northern hardwoods dominated by beech and hemlock.
- This research will contribute to our understanding of the impact of BBD on the Allegheny plateau old growth remnant American beech-Eastern hemlock forest.
- It was in forests very similar to this type that Ehrlich made his seminal observations of BBD in 1934 and now nearly 100 years later, we can observe BBD impacting an old growth forest and learn a lot about this disease complex with the hindsight of those earlier observations
- This project will provide data which can be used to test the USDA FS Forest Vegetation Simulator BBD keyword add-file.
