Summary

A green-tree reservoir (GTR) is a stand of bottomland hardwoods that is intentionally flooded in the fall and winter to support migrating waterfowl. Bottomland hardwood forest plots in the GTR on Felsenthal National Wildlife Refuge (FNWR) are measured every 5-6 years to monitor tree survival, growth, and mortality. This dataset presents the measurements of all the trees in 54 plots during the year 1995. Parameters measured are species, diameter, vigor class, canopy class, and whether or not the tree is a new recruit in 1995. These parameters are defined in the Entity and Attributes section of this metadata file. Additional Information: A series of square 0.1 ha (31.6 m X 31.6 m) permanent plots was previously established between 1985 [...]

Purpose

Water levels within the GTR of FNWR are determined by the operation of a lock and dam downstream of the refuge operated by the U.S. Army Corps of Engineers and to some extent can be manipulated at the request of FNWR managers. Data is collected in the GTR bottomland hardwood forest plots to inform FNWR managers of the effects of past management of manipulated water levels and adapt future management of hydrology to improve GTR forest health.
