EPA issues proposed interim decision on registration review for sulfonylurea herbicides

In July 2016, EPA issued its proposed interim decision on the registration review for 22 sulfonylurea (SU) herbicides. Sulfometuron methyl and metsulfuron methyl were among those 22 SU herbicides. In the interim decision, EPA concluded that there are no human health risks of concern related to continued use of SU herbicides. The agency also determined that there are no direct ecological risks for any taxa other than non-target terrestrial and aquatic plants.

NCASI, Memorial University publish paper on a review of systematic conservation planning

Systematic Conservation Planning (SCP) is an approach to protected areas planning that follows a step-by-step process. In order to determine how well the process has been applied in conservation programs globally, NCASI and Memorial University of Newfoundland conducted a review of the literature on SCP. The findings suggest that protected areas plans varied in how well they considered data uncertainty, and many used so-called “data free” conservation targets without clear rationales, which have been shown to under-represent natural features.

Paper addresses stream temperature response to forest harvesting

In Oregon, the Alsea Watershed Study Revisited has provided a unique opportunity to investigate and compare stream temperature responses to contemporary forest harvesting practices (e.g., retention of riparian vegetation for provision of shade) with the impacts from historical (1960s) harvesting practices (e.g., no riparian vegetation retained). A paper recently published in Forest Ecology and Management presents results from this study.
