Cross boundary cooperation good for ecosystems

A new paper by Mark Rickenbach (University of Wisconsin Madison, and a recent Bullard Fellow), David Kittredge (HF Forest Policy analyst), Bill Labich (regional Conservationist, Highstead), and two others, outlines the reasons why cooperating on land management across boundaries is a superior way to conserve ecosystem services. Ecosystem patterns and processes don't start or stop at individual private property boundaries, yet current public programs and policies focus on individual parcels and incentives.

New Harvard Forest Publication: Impacts of hemlock removal on arthropod communities

Another article in a series of papers describing findings from the Harvard Forest long term Hemlock Removal Experiment has been published in Ecosphere. In this paper, a group of researchers including Harvard Forest Senior Researcher Aaron Ellison, and post-docs Sydne Record and Ben Baiser, look at the effects of the hemlock woolly adelgid and pre-emptive salvage logging on communities of ants, beetles, and spiders in hemlock dominated stands. Relative to intact hemlock stands, in situ death of hemlock and logging/removal of hemlock altered composition and diversity of beetles and spiders.
