Well, I try to stay away from the trees. In general they can be a good asset in the next decade. Sort of like putting money in the bank. Some hobbyist that make woodworking or specialty guitars look for certain wood types and grains. You would be surprised to get offered $500 for a tree that is only 15 years old. If you have a few 60+ year old black wallnut trees, lumber companies pay top dollar for them.
Another group of trees are the black walnut. The natural herbalist pays a good sum per pound coming out and harvesting them. The white oak trees for acorns are another good crop as the local Indians desire them for all sorts of things like; animal feed, acorn flour, bonding glue for shoes, a nutty mix by stretching peanuts for ice cream toppings, acorn meal, winter food for deer, etc.
If you have a water source, having a weeping willow tree to spawn more to sell is another benefit too. People desire these because of the ample shade, hardly anyone is allergic to them, and is ideal for a hammock setup if two are planted about 14 feet apart. If you have a low sport or an area that a natural spring floods the land, a weeping willow is a natural control to prevent the marsh or mucky soil conditions. Medically, the willow has more benefits too.

Do not discount trees. They help as a wind breaker, provide needed resources as food (orchards), medical supplements, construction, soil erosion prevention, marsh control, beauty, etc.
It's easier to sell a plot of land with the ascetics of placed trees than an open field.
