Graduate Exit Seminar - Joseph Hinz

Plan to join Joseph Hinz's graduate exit seminar on December 17, 2024, at 10:00 am via Zoom. Joseph will present, "Multi Scale Evaluation of Early Successional Habitat for Ruffed Grouse in Ohio"

Abstract: Ruffed Grouse (Bonasa umbellus), once widespread in Ohio, have seen population declines due to diminishing early successional forest habitats. Using Landsat imagery, forest inventory, and population data, this study modeled habitat suitability across southeastern Ohio, focusing on regions with potential for targeted management. Results identified dry mesic, dry oak, and upland mesic forest types as the most predictive of grouse presence, with habitat suitability highest in stands aged 5–15 years. Presence-only species distribution modeling highlighted a preference for young forest cover, although data demonstrated a significant public land bias, with 74% of observations occurring on state or federally managed properties. Ground-truthing efforts confirmed limited grouse presence, with only one drumming grouse detected during surveys. These findings emphasize the critical role of active forest management, such as silvicultural practices and disturbance regimes, to create and maintain high-quality habitat. This research provides actionable insights for conservation efforts aimed at stabilizing grouse populations in Ohio's Appalachian and Allegheny Plateau regions.
