This past week we heard from a New Jersey grower direct from the cab of his hi-tech combine as he was harvesting soybean.
The yield monitor in the cab was showing him huge yield differences in real-time between the headlands (edges) of the field adjacent to wooded areas and the rest of the 12-acre field. He considered possible causes but the differences were far too great to be shade, water stress, compaction, or competition from weeds. Nothing seemed to fit the pattern explaining the 45% yield loss seen in the first 2 passes compared with the 50 bushels/acre for the rest of the field.
Recalling a discussion we had some 15 years ago about deer being edge habitat species, he asked, “Could this be deer damage?”
It might well be. Grower reports are coming in from all over New Jersey suggesting that this will be a very bad year for deer damage. Rising intolerable crop losses are being experienced. NJ Farm Bureau President, Ryck Suydam, states, “The costs are just too high, something must be done” to better control deer damage. Contrary to popular opinion, crop damage from deer is the result of how effectively non-farm landowners (public and private) manage wildlife resources on their own properties. We have the knowledge to do a better job controlling deer populations; getting buy-in from all groups to work toward consistent application of effective methods is the hard part.
Myths about Deer Populations
Deer thrive in NJ but we can’t lay blame at the feet of local farms. Deer are unlike other species whose numbers dwindle in the face of urban sprawl.
Landscape modifications carving up habitat – the edges of neighborhood yards, for example – actually support more deer at higher densities per square mile than undisturbed forests. Due to modern NJ settlement patterns, available deer habitat has increased while predation has decreased leading to populations that have outstripped deer carrying capacity for much of our state. When deer populations overwhelm an area, normal deer behaviors bring them into closer contact with humans, resulting in increased incidence of human disease (for example, Lyme disease), auto vs. deer accidents, and competition for suburban landscaping and agricultural crops.

It is important that farmers be involved in policy decisions at the local, state, and federal level because quite often those charged with making policy do not farm and may not realize the impact their actions have on the viability of farms in our state.
