Very interesting, is Gene pleased with the changes to his landscaping or will he remove what the beavers have created? Sounds like a lovely and healthy area was created, those ground ferns are beautiful ;) I would say you are already creating an atmosphere fostering new plant and animal health. Didn't realize the larvae from Zebra Swallowtail butterfly needs the Paw Paw leaves, wow! Ini will be thrilled, just another reason to plant more Paw Paw oxox love you!
