I
should think that the more "management" you do, the more likely you are to attract unwelcome attention. In these times, even a mere trespassing citation can create serious difficulties for a person. But if you don't manage your plantings sufficiently, they won't thrive. It's a bit of a dilemma.
I'll tell you what strikes me as a more immediately-rewarding endeavor in the same spirit. If the forests near you harbor unloved and untended wild fruit or nut trees already, you may find that they are impossible for anyone to harvest because of undergrowth and rough terrain. They may also be unproductive due to the same undergrowth or to shading out by nearby trees. I currently have many trees on my own acreage (pecans and persimmons) in this condition.
Rather than invest all that effort and time to plant a tree that may not thrive at all, why not invest it in improving an existing tree? Much of the work is similar, but the rewards are much more immediate and the effort less likely to be wasted. You can clear out undergrowth and conceal or bury your cuttings, level the area and introduce native groundcover species that don't interfere with the tree's productivity or with harvest of its produce, plant or transplant some inconspicuous native nitrogen-fixers, very discretely reduce shading trees by judicious pruning, make useful but inconspicuous improvements to local groundwater flow, capture, and storage -- you get the idea. The nifty thing is, you can develop a food resource in just a few seasons this way. And if you "get caught", you can make yourself scarce for a couple of years, secure in the knowledge that the tree you improved is certainly still alive and likely flourishing -- whereas if you planted a sapling, you might feel pressure to return and further nurture, irrigate, et cetera.
Obviously this is not an option if the forests near you don't include any native or introduced food trees.
