USFS Northern Research Station New Publications
The Northern Research Station provides leading-edge forest science and technology applications to serve a wide range of clients in the 20-state region of the Northeast and Midwest. Check out our this link where you can view and print the online versions or order paper copies of the publications.
Here are a couple that may be of interest:
GTR-NRS-52. A Guide to nonnative invasive plants inventoried in the north by Forest Inventory and Analysis. Olson, Cassandra; Cholewa, Anita F. 194 p.
The Forest Inventory and Analysis (FIA) program of the U.S. Forest Service is an ongoing endeavor mandated by Congress to determine the extent, condition, volume, growth, and depletions of timber on the Nation's forest land. FIA has responded to a growing demand for other information about our forests including, but not limited to, soils, vegetation, down woody material, and invasive plants. The intent of this guide is to aid FIA field staff in identifying 44 invasive plant species in the 24-state Northern Research Station region (Maine south to Delaware west to Kansas and north to North Dakota). However, this guide can be used by anyone interested in learning about these invasive plants. It contains distribution maps, short descriptions, space for notes, and numerous pictures of each plant.
GTR-NRS-48. Effects of herbicide concentration and application timing on the control of beech root and stump sprouts using the cut-stump treatment. Kochenderfer, Jeffrey D.; Kochenderfer, James N. 10 p.
Application costs and efficacy for two concentrations of herbicide and treatment time intervals were determined for cut-stump treatments applied to American beech (Fagus grandifolia Ehrh.) to control root and stump sprouts in central West Virginia. Glyphosate as GlyproTM (53.8 percent a.i.) was applied to the outer 2 inches of beech stumps from trees ?6.0 inches in diameter at breast height within 0 to 1 and 3 to 4 hours after cutting. In addition, the effects on efficacy of using two concentrations of GlyproTM (50 and 100 percent) were also evaluated. This study demonstrated that a 50-percent solution of GlyproTM was just as effective as a 100-percent solution and that an applicator could wait up to 4 hours after stems had been cut before applying the herbicide, without reducing efficacy.
