I agree. A lot goes on out there at night. I would also put the fencing back up. Critical time for those saplings.
I browsed most posts here but didn’t notice everything and was just wondering if you had identified the Mulberries. Again I probably missed the discussion up above (one is native, one is not).
We had several of the non-native species, here in Raleigh, NC. I left one, and removed the other 2. That one yields a lot of bird-fruit but I confess, it also yields a lot of saplings that I then have to go pull up. I’m getting older and the life of that Mulberry is limited now…
And then it turns out, I found a couple specimens of the native Mulberry across the street (we have a buffered zone around this 5 acre “meadow”; old lake now dried up).
