A recent study shows that fertilization of
southern pines is beneficial with respect to greenhouse gas mitigation. In
other words, fertilization increases carbon sequestration in forests and forest
products by an amount that far outweighs CO2 emissions associated
with fertilizer production, transport and application.

It is generally understood that risk of extinction tends to increase
as population size declines. On the other hand, attempting to conserve hundreds
of rare species would have potential to spread resources too broadly. A
discussion of this dilemma and related topics is presented in “Understanding
rarity: A review of recent conceptual advances and implications for conservation
of rare species.”

The International Union of Forest Research
Organizations (IUFRO) will host the XXIV IUFRO World Congress in Salt Lake City
October 5-11, 2014. The Congress will highlight the contributions forest
science is making to address the world’s environmental, social, and economic
challenges. All who share an interest in the future of forests and forest science
are invited to submit session proposals. Proposals
should be submitted no later than April 30, 2013.
The Wildlife Society
recently released Technical Review 12-03, Effects
of Bioenergy Production on Wildlife and Wildlife Habitat, authored by a TWS
committee chaired by Dr. Susan Rupp of Enviroscapes Ecological Consulting. Two
NCASI scientists, Dr. Jake Verschuyl and Dr. Ben Wigley, served on the
committee. The review addresses bioenergy production on agricultural lands and
croplands, grasslands, forest ecosystems, and algae and aquatic feedstocks.

John D. Hewlett (University of Georgia) started a field
study of forestry BMPs in the early 1970s in two watersheds at the B.F. Grant
Memorial Forest. A recent study in the same watersheds has produced strong
evidence that contemporary BMPs are effective in controlling water quality impacts
of forestry operations. Results of the recent study are presented in “A paired
watershed investigation of silvicultural best management practices revisited: B.F.
Grant Memorial Forest, Georgia.”
