Paper reports on models for predicting delivery of sediment to streams

Forest road stream crossings, when constructed with inadequate implementation of best management practices, have potential to deliver sediment to streams. Models have been developed to estimate soil erosion and sediment delivery and can be used by managers to predict erosion-prone areas. Recently, Virginia Tech, WestRock, the U.S. Department of Agriculture, the U.S. Forest Service, and NCASI collaborated to (1) evaluate performance of three erosion models by comparing model simulations to trapped sediment measurements, and (2) assess model utility for identifying stream crossing approaches that may require additional BMPs.

Bottomland and swamp forest symposium planned in North Carolina

Recently, organizers announced that a Bottomland and Swamp Forest Symposium will be held October 31 – November 2 in Wilmington, North Carolina. The Symposium has been designed for anyone with ecological or economic interest in bottomland hardwood and swamp forest silviculture. It will feature presentations by researchers and practitioners from throughout the southeastern US who have experience in these lowland forest types.

Publication describes how sample size and other factors affect estimates of wildlife population trends

Recently, Dr. Craig Loehle of NCASI and Dr. Nasser Arghami (deceased) used a 46-year series of data from the Breeding Bird Survey in the US to evaluate how sample size and the number of years for which population estimates were available influenced inferences about wildlife population trends. In addition, they used a 100-year-long data set for breeding Sandwich terns from the German North Sea coast. In their analyses, they attempted to account for random influences on population trends.

U.S. Forest Service releases report on forest and grassland carbon

Recently, the U.S. Forest Service released a report titled Considering Forest and Grassland Carbon in Land Management. The report describes the role of forest and grassland ecosystems in the carbon cycle and provides information for considering carbon as one of many objectives for land management activities. Chapters address the global carbon cycle, ecosystem carbon storage and fluxes, carbon monitoring and accounting, carbon and land management, and U.S. Forest Service strategies and management.
