We plan to plant about 500 seedlings next spring in a nursery area, and about 300 larger seedlings around the perimeter of the property along the county roads. 

If you're property is in SD - there's a great local native plant nursery in Escondido (a little bit north of San Diego - probably others around) - called Las Pilitas.

They want to turn bedrooms into nurseries, not tear-downs into McMansions.My $0.02 ...

If it had been an older stand of lumber quality trees the harvester would have paid for the wood and done it all at once because of the value.If they're another type of tree they may have value as landscaping trees(Oak, Holly, Birch, Sycamore, Sweet Gum) and you might be able to get a nursery out to dig them all for sale as landscaping trees.That may be something that to consider as well is find a nursery that would like to lease the property for a tree farm.

Tommy’s is attached to the western side of Oakland Nursery.

Many of these lots are undeveloped or have nurseries or tree farms, etc.

(heck, I drove 2 hours to save 4K on large purchase) I purchased landscaping stuff at a nursery and asked for a discount..My son was shocked at the 10% discount, but I will refer the nursery to others and do more business because the MGR made a decision...."

I'm purely independent now, working as a landscaper and selling plants (starting a nursery business).

As an entrepreneur, you should not care if they use it as a nursery or a warehouse, it is a business, unless you have the capital to play nice and be chossy for your own self-indulgence.   

They do allow (Oregon/Marion county specifically) a farm stand use, Ag storage, even tractor sales, nursery, farm.
