Productive Potential

Abstract White pine (Pinus strobus L.) is planted extensively following reclamation of surface-mined land in the eastern coalfields. Little information exists on the productive potential of forests growing on reclaimed mined land and the response of these forests to intermediate stand treatments such as thinning. A thinning study was established in a 17-year-old white pine stand growing on a reclaimed surface mine in Wise County in southwest Virginia. A random complete block design was used to evaluate the growth response 9 growing seasons after thinning, when the stand was 26 years old. Stand parameters were projected to age 30 using a stand table projection. Site index of the stand was found to be 105 ft at a base age of 50 years. Thinning increased the diameter growth of the residual trees to 0.3 in. year−1 compared with 0.2 in. year−1 for the unthinned treatment; however, at age 26, there was no difference in volume or value per acre. When projected to age 30, the unthinned treatment had a volume of 6,530 ft3 ac−1 but was only worth $3,564 ac−1, whereas the thinned treatment was projected to have 6,654 ft3 ac−1, which was worth $4,559 ac−1 due to a larger percentage of the volume in sawtimber size classes. These results indicate that commercial forestry is a viable alternative for reclamation of surface-mined lands and that stands growing on reclaimed mined land can respond well to intermediate stand treatments.

Growth Analyses

Abstract We followed the growth response of naturally regenerated 12-year-old white pine for 4 years after a shelterwood removal cut in a mixed red and white pine stand having an overstory that was significantly reduced by windthrow at the beginning of our study. Postrelease overstory density was reduced to levels (4.5 m2 ha) that did not significantly influence any regeneration growth parameter while understory woody competitors taller than sample trees negatively influenced growth. Analyses revealed differential response to release based on prerelease growth rates with slower-growing trees responding fastest. Release shock persisted for the fastest prerelease growers up to 4 years after harvest.

Partial Release

Abstract We measured the response of white pine (Pinus strobus L.) saplings after partial release of a hardwood overstory on three sites in central Minnesota. Both height and diameter growth increased quickly after release compared to prerelease growth. Diameter growth response was related to prerelease diameter growth, but not to initial size of the sapling (diameter at time of release). On the other hand, height growth response was strongly influenced by the initial height of all trees, but not related to prerelease height growth in the largest saplings (initial heights > 8.76 m). Increased release intensity (i.e., difference between prerelease and postrelease overstory densities) resulted in higher diameter and height growth responses. The height/diameter ratios decreased after release, indicating that stability as well as growth increased after the release. North. J. Appl. For. 17(3):89–94.
