I have an approximately 4 acre woodlot with 1/3 Hemlock and the rest is about equal parts Hard maple, Hickory, Ash, and Beech. There are about 12 rather large (24" diameter) various above mentioned hardwood. Then about 50 medium sized trees, and then about 100 smaller trees.(very rough numbers). Some of the medium and small trees need to be thinned. I have others place to cut wood (mainly ash and silver maple there and plenty of it). What is the best way to use this woodlot? I will leave the hemlock alone for a windbreak. I have been told to leave large trees because they produce the new saplings. Is this true? I am thinking about cutting 1-large, 5- medium, and thin out the small trees as needed, each year. Is this a good plan? Thanks.
