Abstract: Ruffed grouse (Bonansa umbellus) populations are in a steady decline due to the loss of early successional forests. Our study focused on the suitability of ruffed grouse habitat which is considered an area with adequate food and cover in. We used a habitat suitability index designed for ruffed grouse in Colorado that included average height of woody stems, percent conifers, density of mature yellow birch, and total equivalent stem density as the variables that indicate whether an area has suitable cover and food for ruffed grouse. Using the habitat suitability index we measured the vegetation in five forest harvest methods including: single tree selection, two-age cut, shelter-wood cut, clear-cut, and a control plot to determine if a habitat suitability index developed in Colorado can be used to assess habitat suitability for ruffed grouse in New York. These plots are located in the Adirondacks in Northern New York State at the Paul Smith’s College Visitors Interpretation Center (VIC). Our results suggested that 14 years after harvest a single tree selection harvest method has the highest overall habitat suitability (0.95) for ruffed grouse. This is different from other studies we found that indicated clear-cut was the most suitable forest harvest method for ruffed grouse. We also projected the change in habitat suitability for height of woody stems over time for the clear-cut based on the yearly growth rate of 0.656 feet. Based on our findings from the study we made recommendations to land owners and land managers to develop and promote short term and long term suitable habitat for ruffed grouse. These recommendations included using a variety of forestry practices that included: single tree selection, shelterwood, and clear-cut because ruffed grouse require a variety of different cover types and habitat over their lifetime.
