Re: Q: Theorictical Honey per Acre
Around here, ungrazed former pastures are colonized by cedars, and then eventually hardwoods will overtake the cedars. Over time, without intervention, it will return to forest.
I have planted 300 thornless blackberry plants, of 6 varieties, plus 30 raspberries. They produce well, but to fill a 100 acres would take a lot of labor in terms of maintenance.
I would first explore to see whether someone local is interesting leasing a portion of that land to run cattle.
Assuming you don't want a return to forest, if the land is not too hilly to bushhog, I would seed with a mix of "wildflower/weeds", and set a bush hog rotation plan so that the entire property is mowed n segments, over a span of every 3 years or so.
