| 2714063 | Appalachian mixed hardwoods | 65-year old unmanaged stand. Typical cove hardwood stands, with basal areas ranging from 120 to 200 square foot/acre. Yellow poplar basal area composes 30-90% of total. Red oak basal area ranges from 5-40% of total. Red maple averages 10% and cherry averages 3% of basal area. Stands are vertically stratified by species based on silvical growth habits, especially shade tolerance. West Virginia site. | |
| 2714062 | Appalachian mixed hardwoods | 65-year old unmanaged stand. Typical cove hardwood stands, with basal areas ranging from 120 to 200 square foot/acre. Yellow poplar basal area composes 30-90% of total. Red oak basal area ranges from 5-40% of total. Red maple averages 10% and cherry averages 3% of basal area. Stands are vertically stratified by species based on silvical growth habits, especially shade tolerance. West Virginia site. | |
| 2714061 | Appalachian mixed hardwoods | 65-year old unmanaged stand. Typical cove hardwood stands, with basal areas ranging from 120 to 200 square foot/acre. Yellow poplar basal area composes 30-90% of total. Red oak basal area ranges from 5-40% of total. Red maple averages 10% and cherry averages 3% of basal area. Stands are vertically stratified by species based on silvical growth habits, especially shade tolerance. West Virginia site. | |
| 2714071 | harvest | 2.47 acre (1 ha) 65-year-old stand, after 30 cm (12") diameter-limit (dbh) harvest (non-silvicultural harvesting practice common in the region). Basal area is 36 square feet per acre dominated by yellow-poplar and oaks. Red maple, and other hardwoods have the highest densities (trees/acre). | |
| 2714060 | Appalachian mixed hardwoods | 65-year old unmanaged stand. Typical cove hardwood stands, with basal areas ranging from 120 to 200 square foot/acre. Yellow poplar basal area composes 30-90% of total. Red oak basal area ranges from 5-40% of total. Red maple averages 10% and cherry averages 3% of basal area. Stands are vertically stratified by species based on silvical growth habits, especially shade tolerance. West Virginia site. | |
| 2714064 | seed tree | Stand was harvested two years ago. Residual basal area 20 square feet per acre; 16 trees per acre with an average dbh of 15". Site was logged with chainsaws and skidders. Primary species are Northern Red Oak (Quercus rubra), Chestnut oak (Quercus prinus) and White oak (Quercus alba). | |
| 2714065 | seed tree | Stand was harvested two years ago. Residual basal area 20 square feet per acre; 16 trees per acre with an average dbh of 15". Site was logged with chainsaws and skidders. Primary species are Northern Red Oak (Quercus rubra), Chestnut oak (Quercus prinus) and White oak (Quercus alba). Note white and red oak seedling in the foreground | |
| 2714066 | Appalachian mixed hardwoods | Mapped 2.47 acre (1 ha) 65-year-old stand. 402 stems (163/A) were located and crown area mapped using survey laser. Basal area is 140 square feet per acre (>4" dbh) dominated by yellow-poplar (yellow). Other species include: red maple (red), oaks (brown) and other hardwoods (blue). | |
| 2714067 | shelterwood | Mapped 2.47 acre (1 ha) 65-year-old stand after shelterwood seed cut. 176 stems (71/A) were located and crown area mapped using a survey laser. Basal area is 75 square feet per acre dominated by yellow-poplar (yellow). Other species include: red maple (red), oaks (brown) and other hardwoods (blue). All understory trees 4-8" dbh were removed, which eliminated most of the red maple. | |
| 2714068 | harvest | Mapped 2.47 acre (1 ha) 65-year-old stand, after 41 cm (16") diameter-limit (dbh) harvest (non-silvicultural harvesting practice common in the region). 195 stems (79/A) were located and crown mapped using a survey laser. Basal area is 40 square feet per acre dominated by yellow-poplar (yellow) and oaks (brown). Red maple (red), and other hardwoods (blue) have the highest densities (trees/acre). | |
| 2714069 | harvest | Mapped 2.47 acre (1 ha) 65-year-old stand, after 41 cm (16") diameter-limit (dbh) harvest (non-silvicultural harvesting practice common in the region). 195 stems (79/A) were located and crown mapped using a survey laser. Basal area is 40 square feet per acre dominated by yellow-poplar (yellow) and oaks (brown). Red maple (red), and other hardwoods (blue) have the highest densities (trees/acre). | |
| 2714070 | harvest | 2.47 acre (1 ha) 65-year-old stand, after 41 cm (16") diameter-limit (dbh) harvest (non-silvicultural harvesting practice common in the region). Basal area is 40 square feet per acre dominated by yellow-poplar and oaks. Red maple, and other hardwoods have the highest densities (trees/acre). |
