During the last century, numerous models have been developed to predict soil erosion and concomitant sediment deposition. Most have been shown to be inadequate and/or inaccurate in one respect or another. Historically, erosion model results have been compared with sediment outflow from watersheds, providing no information regarding sources and sinks of erosion and deposition within them. This paper documents the application of the new-generation Unit Stream Power Erosion and Deposition (USPED) model at the U.S. Army’s Fort Campbell, Kentucky / Tennessee. The USPED model is relatively...

A new long-legged fly species, Chrysotus soya sp. nov. (Diptera: Dolichopodidae), is described and illustrated from specimens collected in soybean fields near Brookings, South Dakota, USA. The abundance of this species in soybeans suggests it plays an important role as a beneficial predator.

Northern pike are among the most exciting freshwater fishes to land because they tend to put up quite a fight. This species is broadly distributed outside its native range due to human transport and subsequent expansion. Where pike have been introduced, native fish like bull trout, which are listed as Threatened under the Endangered Species Act (ESA), are suffering dire consequences as this long-lived, generalist top predator is using native fish as a food source. A recent publication, “Mechanism of northern pike invasion in the Columbia River basin,” describes how a team of Tribal, State,...

Earlier this year, the U.S. Department of Agriculture and the U.S. Forest Service released a new 10-year plan, Confronting the Wildfire Crisis: A Strategy for Protecting Communities and Improving Resilience in America’s Forests, to substantially reduce fire risk across the country. The Wildfire Crisis Strategy calls for ramping up forest treatments on Federal, State, Tribal, and private lands well above current levels. Public and stakeholder engagement, consultation, and collaboration are critical to successful implementation of the strategy. Best available science can inform how to...

Westslope cutthroat trout (Oncorhynchus clarkii lewisi, WCT) were highly valued by Idaho’s Indigenous people and subsequent immigrants. Historically, WCT were extremely abundant, widely distributed, and the dominant trout in central and northern Idaho. Early 20th-century anglers enjoyed exceptional fishing; St. Joe River anglers reported WCT catches of 35 pounds in 1 hour! Despite restricted harvest and habitat protections since 1899, many Idaho WCT populations declined, primarily from habitat degradation and excessive harvest. By the 1960s, WCT in several major drainages were on the brink...

The request from the U.S. Department of Agriculture, Forest Service’s Region 5 to Area Command Team (ACT) 2 was straightforward: Identify potential gaps between wildfire resource needs and resource availability for October through December 2020. The Fire Weather Outlook at this time was predicting that parts of California and the Southwest would see higher-than-usual fire activity into the fall and winter. In preparation for the worst-case scenario, the region needed to identify the regional and national availability of personnel and equipment, including crews, engines, aircraft, and...

This summary report provides an overview of findings from the fourth annualized inventory of Delaware forests based on data collected from 2012 to 2018. Forest land area remained stable at 359,000 acres, and 51 percent of forest land is in the oak/hickory forest-type group. Forests in the State continue to mature, with 76 percent in large diameter stands and 65 percent in stands older than 60 years of age. Total live-tree net volume on timberland is 907 million cubic feet, and 92 percent of that volume is in growing-stock trees. Annual gross growth of 29 million cubic feet less annual...
