Black walnut stumpage is rebounding quite nicely.  Rather than selling your standing timber directly to a logger, might I suggest you contact an independent consulting forester to assist you in marketing your timber to the highest prospective timber buyer.    
To ascertain local log demand and sawlog/veneer prices in New York, might I also suggest you contact a local New York state forester or independent consulting forester:
