I didn't this time, but ...?
Walking along a fire road in a public forest, I noticed a putty root orchid leaf at an odd angle. These orchids are common enough, but it's still cool to see their unique stripey leaf. This particular one was about to fall out of an eroding embankment -- bulb almost totally exposed -- probably doomed.
Taking it home was out of the question, since it is illegal, and, more importantly, unable to live in my town garden. But maybe I could have saved it -- moved it gently from the crumbling embankment, back a couple of feet into the forest. Closer to a few others of its kind.
What would you have done?
