Literature review on sustainable wood procurement

A NCASI-sponsored study was published earlier this year in a paper titled “Sustainable wood procurement: What the literature tells us” (Journal of Forestry 110: 157-163).

Habitat selection model explains source-sink paradox

Dr. Loehle’s article is titled “A conditional choice model of habitat selection explains the source-sink paradox” (Ecological Modelling Vols. 235-236:59-66). The paper shows that sink habitats are not necessarily “ecological traps” that reduce the long-term viability of species, but rather can make positive contributions to viability that depend on the relative abundance and spatial arrangement of sources and sinks across landscapes.

Summary of NCASI comments on draft conservation strategy for the gopher tortoise

In August 2012, the U.S. Fish and Wildlife Service released for public comment a draft range-wide conservation strategy for the gopher tortoise. The strategy provides a thorough overview of the tortoise’s biology, potential threats, and draft conservation objectives and actions. Nevertheless, NCASI surveys and research, and the experiences of NCASI member companies, suggest that the conservation strategy could be strengthened by recognizing the following points.

Forest Products Lab opens nanocellulose facility

The U.S. Forest Service’s Forest Products Laboratory (FPL) in Madison, Wisconsin recently opened a $1.7 million pilot factory to process wood pulp into nanocrystalline cellulose, a lightweight material said to be as strong as Kevlar. This is only the second such facility in the world.

Study to assess stable isotope mapping to predict forest retention of fertilizer nitrogen

Watershed and site-based research is needed to address fertilizer nutrient fate questions but is costly and time-consuming to implement and difficult to extrapolate beyond the sites investigated. Fertilizer fate models provide broader-level assessments but are limited by a lack of comprehensive field data for their development and testing. NCASI is supporting a new approach called stable isotope mapping that could provide an index of fertilizer nitrogen retention or leaching in forest stands.
