It’s really hard to grade an area to protect the wildlife when the wildlife wants to blow you up. The explosions make smoothing the dirt a lot harder, and for the matter, they make ensuring you have enough dirt harder.
Still not a fan of the exploding giraffe-corgis is what I’m saying.
On the other hand, I chopped down a whole lot of conifer today and I’m thinking perhaps instead of grading this hole I’ll stick a building on top of it to keep the animals from falling in. That’s probably cheaper and more efficient — definitely more effective than fencing. And logs may not be super explosion-proof but if I’m not living here anyway I’m not sure I care.
