EPA releases interim registration review decision for 22 sulfonylurea herbicides

EPA recently released its interim registration review decision for 22 sulfonylurea herbicides. This decision is designated as “interim” rather than “final” because endangered species, endocrine disruption, and pollinator assessments have not yet been completed. The interim decision establishes a set of common labeling requirements for all 22 sulfonylurea herbicides, along with specific labeling requirements for some individual herbicides.

Forestry BMPs found to reduce the risk from forest herbicide use to aquatic organisms in streams

Recently, Dr. Vickie Tatum of NCASI and others authored a paper, which appeared in Forest Ecology and Management, that assessed the effectiveness of modern forestry BMPs for reducing the risk of forest herbicide use to aquatic organisms in streams. In the paper, the authors summarized results from recent studies of operational forestry applications of herbicides in which data on herbicide concentrations in potentially impacted streams were collected.

Paper evaluates potential for sampling bias when detecting population trends in amphibians

Recently, Dr. Craig Loehle and Philip Weatherford of NCASI developed a paper that evaluated the challenges associated with using historic data gathered over time to estimate population trends for rare species. Studies of pond-breeding amphibians were used to illustrate issues that may arise with retrospective studies; however, the principles discussed are applicable across taxonomic groups.

NCASI participating in study of bats in Coastal Plain working forests

Recent research by the University of Georgia that was supported by NCASI and its member companies found that, during summer, working pine forests in the Coastal Plain support a large proportion of the bat community associated with forests of the region. Little is known about the winter habitat relationships of bats in general, and the northern long-eared bat in particular, in the southeastern Coastal Plain. To address this information gap, NCASI is collaborating in research to better elucidate habitat relationships of bats during winter in the lower Coastal Plain of Louisiana, Texas, and Virginia.
