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

NCASI’s 2012 West Coast Regional Meeting will be held October 2-3 in Vancouver,
Washington. The meeting will include a full-day forestry technical
session on October 3.
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
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.
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.
