As deer hunting season approaches, or continues as the case may be for early archery season, a recent post about the contribution of hunters to others in their community via "Hunters for the Hungry" reminded me of the important contribution that deer hunting can make to the health and sustainability of our hardwood forests.
Recent studies have added to the depth and breadth of information regarding the negative impacts that deer have on natural (and urban incidentally) ecosystems. A survey of foresters in NY by Cornell's Human Dimensions Research Unit reports that foresters identify deer browsing pressure as the most common threat of forest regeneration in most regions of the state. Invasive and interfering plants also factored prominently in the list of barriers to regeneration. Similarly, a study by The Nature Conservancy using USFS field data assessed potential barriers to regeneration. They found that regeneration was limited in many areas, with deer as a potential factor. I have attached a pdf copy of the report to this post, and apologize that I can't recall where I found the document on the NY TNC website. Maybe some can share the direct link.
Picture 1. An image of hardwood regeneration that would be nice to see more commonly. Picture by Gary Goff.
Picture 2. Evidence of a deer problem. This fenced exclosure in Ontario County NY shows the impact of deer on native forest vegetation. Without the fence, it is often too easy to not see the problem because the deer consume the evidence.
Picture 3. Deer consume approximately 7 lbs (fresh weight) of forage per day, some percentage of which may be hardwood seedlings. If there are approximately 600 seedlings per pound, and there are 30 deer per square mile in the forest for 3 months....how many seedlings to they eat? How many seedling do you have in your woods?
