eastern hemlock

To observe differences in tree-ring width during frost and non-frost years, we used superposed epoch analysis and a t-test to analyze tree-ring data from three coniferous (eastern hemlock, white pine, and red pine) and three deciduous (red maple, red oak, and bigtooth aspen) trees.

To wrap it up, discover how a fly could be the answer to our eastern hemlock's troubles in "It's a Bug-Eat-Bug World." The hemlock woolly adelgid is responsible for the death of large numbers of hemlock trees from the Carolinas to New England, and it's causing lots of problems.

This converse pattern is consistent with earlier studies on olefin-imidacloprid concentrations in eastern hemlock that were documented to increase as imidacloprid concentrations decrease (Dilling et al.

prinus, 10%), eastern hemlock (Tsuga canadensis, 8%), white pine (Pinus strobus, 6%), American beech (Fagus grandifolia, 4%), and sweet birch (Betula lenta, 3%) as associates (Townsend and Meyer, 2002).

His work with a natural enemy of the hemlock woolly adelgid, an invasive insect pest, could improve chances for the survival of the Eastern hemlock, long a favored tree in New England forests for both economic and ecological benefits.

writes that western hemlock differs from eastern hemlock in that "the wood is of very fine texture, light in weight and straight in grain, and it has about the same workability as pine."

The Eastern Hemlock (Tsuga canadensis), and the Carolina Hemlock (Tsuga caroliniana), are very important components of the natural forest ecosystems of the eastern United States.

This study compared the rate of leaching from unincised eastern hemlock to that of wood that had been incised to two depths and with two density patterns.

Stand response was examined by establishing 24-400 [m.sup.2] sample plots within eight recently infested Tsuga canadensis (eastern hemlock) stands greater than three ha in size.

In this paper we use a similar approach to study the invasion of forests by eastern hemlock (Tsuga canadensis) 3200 years ago (Davis 1987).

At 147.6 feet, the tallest accurately measured eastern hemlock in the Northeast grows in Cook Forest.
