Walking around the lake near my house I’ve noticed the preponderance of snags – dead trees left standing, most of them without their tops. Here’s one along the path.
Knowing they’re important for wildlife, I was happy to see so many, but it took a bit of googling to discover just HOW important. According to the Washington Dept of Fish and Wildlife, they actually provide MORE habitats for wildlife dead than alive. No wonder they’re also called “wildlife trees.”
Thanks to that link, I’ll forever be envisioning these adorable critters whenever I see a snag. But they’re just the poster animals for snags: “In total, more than 100 species of birds, mammals, reptiles, and amphibians need snags for nesting, roosting, shelter, denning, and feeding; nearly 45 species alone forage for food in them.”
That link goes on to tell us how to look at them up close, which trees make the best snags, how to create them from live trees, and how to relocate them (which seems crazy, right?).
So now that we’re all in for snags, can we have them in our yards? Large ones, maybe: “Try to incorporate one or more snags into your landscape keeping old and damaged trees when possible. Retain trees and tall shrubs near the planned snag to protect it from wind and provide a healthier environment for wildlife.
“In urban areas, tall snags are best located away from high activity areas, where they won’t pose a hazard if they fall. Trees that lean away or are downhill from structures and other areas of human activity present little or no risk.”
Well, that’s disappointing, though it explains why there aren’t snags anywhere near my home. But in my disappointment I asked the experts at the Garden Professors Blog Facebook Group (which just added its 10,000th member!) if they’d leave a snag anywhere near their home and the grown-ups responding included actual risk-assessing arborists – certified ones!
Their advice: IF an expert has concluded that a tree must come down, it’s okay to leave some standing for wildlife, as long as it’s not tall enough to fall on something in a bad wind. One recommended leaving the cut portion of the tree on the ground at the site. (Got room for that? Not me.)
Others said they’d sure like to see more in the media about wildlife trees and their importance. One ray of hope? Efforts to change forestry policies to leave more for wildlife.Posted by Susan Harris on February 17, 2017 at 10:13 am, in the category Gardening on the Planet, It's the Plants, Darling.
