Recently, authors with NCASI, Nutter and
Associates (Athens, Georgia), and the University of Saskatchewan published
results from a study that characterizes concentrations of four forest
herbicides in streamwater during and after aerial application of herbicides in
Oregon’s Coast Range. The authors found very small herbicide concentrations in
streamwater for brief periods following the first few storm events after the
application. However, the concentrations were well below the levels shown to
have adverse effects on fish, amphibians, or invertebrates.

NCASI recently published Technical Bulletin No. 1038, Effectiveness of BMPs for Reducing the Risk of Adverse Impacts of Herbicides on Aquatic Organisms, prepared by Dr. Vickie L. Tatum. The report summarizes results from three recent studies that evaluated effectiveness of modern forestry best management practices for protecting water quality when forest herbicides are applied. The Technical Bulletin also describes the outcome of an EPA-type preliminary risk assessment
for aquatic biota using measured stream water herbicide concentrations from those studies.
In response to a petition submitted by the
Center for Biological Diversity, the U.S. Fish & Wildlife Service is
continuing its review of the status of the eastern diamondback rattlesnake to
determine whether the species warrants listing under the Endangered Species Act
as a threatened or endangered species. NCASI is currently soliciting
information about observations of the snake to improve understanding of its
distribution and habitat associations. Individuals encountering an eastern
diamondback rattlesnake are invited to complete a short online survey.
