Since the 80’s I have advised sellers or buyers of vacant land to first do an accurate assessment of any possible wetlands and what may be living there. Is there a mud puddle after a rain, caused by a clay layer beneath the surface (a perched water table)? Remove any wetland vegetation. Punch a lot of holes through the clay, add gravel to promote drainage, top off with topsoil and plant upland vegetation. If you don’t, you’ve got a wetland that renders part or all of your property off limits to development.
Any critters living there? Get rid of them if there’s any chance they could be considered “endangered”. Trap ‘em and move ‘em if you can; do what you have to if you can’t. If your property is declared habitat its value drops to zero.
Can you say “night vision goggles”? Working in the dark can be tough.
