Yeah but now I have to consider suicidal teenagers and climate change. I'll be lucky to live to 70, my (potential) kids, maybe 60, if the environment doesn't completely collapse.
If you haven't yet, you may want to hire a professional forester. At 70% loss they'd likely pay for themselves many times over and save a lot of headache.
What sort of evergreens are you planting? Are they native? I replanted a clearcut a year or so ago and even with an abnormally hot summer and a dry fall I'm looking at 30%, tops.
Out of curiosity, why is Obsidian closed source? It doesn't look like you charge for anything, and with the size and type of following you have, you'd probably see some really cool stuff get sent your way.
