Abstract

Abstract Forest management and planning efforts often account for many resource objectives and benefits, including wildlife habitat. In particular, newly approved management goals and harvest targets on state lands in Minnesota were examined for their potential impact on wildlife habitat. Using a list of stands planned for potential harvest and a regional wildlife habitat model, habitat effects were assessed for 173 native, forest-dependent wildlife species on state lands. Leveraging forest type– and region-specific harvest probabilities and post-examination lag times to harvest, three simulation efforts covering the spectrum of possible outcomes were used to estimate habitat change from 2020 to 2030. In the most realistic simulation, 31.8% of species exhibited statistically significant positive habitat change, 11.6% significant negative change, and 56.6% nonsignificant or no change. Compared with simulations reflecting more extreme levels of harvest, the realistic simulation showed the greatest compromise between negative and positive shifts in habitat. Results reflect tradeoffs in wildlife habitat preferences such that changes in management that positively affect certain species often negatively affect others. Tradeoffs may be addressed by providing flexibility to individual managers where a targeted prescription is justified for a specific species, all while continuing broad statewide forest management goals.
