contact the QDMA, they have reps that will come out. you can also do the research and do it yourself. If it is old growth woods you can do selective harvest. Or, if it is fields you can hire a farmer to plant food plots.
NY DEC will provide this service for you for free, You can have a DEC Forester come out and do a walk through on your land, explain to him your goasl and what your looking to achieve. He will then put together a Forest Management Plan for your land. He can also go over some of the cost share programs that are out there, but having a Forest Management Plan is the first step in applying for any of the cost share programs.
Go on the DEC website and look around, you'll need to contact the regional office for what region your property is in, they will be able to give you the contact information for the forester that services your region..
There are also some private companies that basicly do the same thing, execpt you need to pay for it....One real good company is North Country Whitetails, they will come down and do a walk through with you on your land and give you some ideas, they also hold workshops for land owners at there place which is located in NY
Also check out QDMA some real good information from these guys, nothing better then having your own place to work on improving the habitat, Ive been doing for years on my Place in NY [up][up]
Contact the county's Soil and Water Conservation District. They offer many programs as well. Won't cost you anything for them to come down to the property and give you recommendations. They will also know of other programs that Fish and Wildlife or other conservation programs from other government agencies have.
