HLTH-2: July 2000 Progress Report
"How have biological agents including insects and disease influenced the overall health of the South's forests and how will they likely affect it in the future?"
Question Managers: Denny Ward and Paul Mistretta
GIS And Data Manager: Ed Yockey, USDA Forest Service, Forest Health Protection, Asheville, North Carolina
July 18-19, 2000, Nashville TN
APPROACH: Our approach includes (1) determining the most significant pest agents impacting the southern forests, (2) determining the location of the cover type at risk, (3) collecting and summarizing historical data on pest outbreaks, and (4) obtaining expert opinions on the likely impact of individual pests. (5) producing a document with accompanying maps and stating the likely future impact of biological agents on the southern forests.
RESULTS TO DATE
- Eleven cover types or species of trees have been selected including:
- white pine
- hemlock
- spruce/fir
- loblolly/shortleaf/slash/Virginia pines
- longleaf pine
- upland/northern hardwood
- bottomland hardwood/cypress
- oak/pine
- live oak
- Biological Pests selected for detailed analyses:
- annosus root rot
- southern pine beetle
- hemlock woolly adelgid
- balsam woolly adelgid
- other bark beetles
- fusiform rust
- littleleaf disease
- reproduction weevils
- tip moth
- Texas leafcutting ant
- Gypsy moth
- Borers
- Forest tent caterpillar
- Fruit tree leaf roller
- Oak decline
- Oak wilt
- Chestnut blight
- Dogwood anthracnose
- Beech bark disease
- Butternut canker
- Seventeen experts have been identified to give their opinions on individual biological agents by answering a set of seven questions outlined in the work plan.
- Twelve data layers (GIS-Arc INFO) for insects and diseases have been acquired.
- Eight related data layers (species and cover types) have been acquired or developed.
- We have requested data on six host species and 3 cover types from FIA to complete the risk assessment for significant pests.
- Additional items requested from FIA such as stand age distribution, location of remnant chestnuts larger than one inch.
