Careful What You Prune and Fell

With apologies to Mr. Kilmer:

I know I must look hard to see
A squirrel’s nest in a leafy tree
Raccoon dens, too, elude my sight
As tree trunks reach their tow’ring heights

Most of us know by now that landscape and tree services can imperil our wild neighbors and their homes.

The climate crisis is making things worse, as in many areas squirrels, for instance, are now giving birth three times a year instead of two.

The rules are pretty simple.

  • Is the work even necessary? Dead trees provide habitat for hundreds of species. Keep them around, if you can.
  • Schedule the work for the times of year when wild animals are least apt to be raising dependent young. November through February and late May to mid-July are still the best times in most areas of the United States, but global heating is impacting this.
  • Before work begins, watch for any activity that might indicate the presence of nests or dens.
  • Ask anyone you hire to keep a lookout for nests and dens while they do their work.
  • Tell anyone you hire you do not want any animals harmed or active animal homes disturbed.
  • Tell anyone you hire to alert you immediately if animals are harmed or left homeless.

If the worst happens, use Animal Help Now to find expert assistance in caring for injured or orphaned animals.

Leave injured wildlife alone?! On what planet???

Two writers for the Dear Science section of the Washington Post stated today that injured and “lost” wildlife should be left alone. The authors correctly write that many young animals who appear to be orphaned are simply being left alone while Mom is out getting food or distracting predators. They also correctly state that helping distressed wildlife can be dangerous and should involve professional help.

But somehow they convince themselves that a bird hitting a window is part of a natural process. Their conclusion references a quote by Don Despain, a retired National Parks Service ecologist. Here the authors liken a typical human urban environment with the relatively intact Yellowstone ecosystem:

In nature, an injured animal — say, the bird in your back yard with a broken wing — will become food for a predator — perhaps an owl. The remains that the owl doesn’t eat will go on to feed microbes that fertilize the soil, which in turn gives rise to new plants, which will feed the insects that become a meal for future birds. This whole system is the “wildness” that Despain speaks of. It’s worth thinking about the next time you come across an injured bird.

Rescue scenario of bird injured from window strike
                          Let him suffer and die? No!

Actually, it’s not worth thinking about. That’s time wasted that could be spent trying to save the bird’s life. Here’s our response, published in the comments section:

Dear Science, we couldn’t agree more about the dangers of “kidnapping” young wild animals whose parents are simply out of sight. And we couldn’t agree less about the conclusion you’ve come to regarding letting nature take its course. Prof Daniel Klem states in peer-reviewed literature that about one billion birds are killed by striking windows in the United States each year. Prof Klem estimates that another billion are injured. That’s 30 per second killed, and another 30 per second injured. Surely nature can’t be so out of balance as to benefit from this anthropogenic disaster. Another billion small mammals are killed by cats in this country every year. Two billion birds. And another 500,000 animals are killed in the U.S. every day by motor vehicle strikes. So we should let the millions of survivors suffer and die? No! We should try our best to help them. This country has an amazing network of wildlife emergency professionals who can help us. As you rightly point out, it’s very important to bring them in as soon as possible on an emergency. To help you find them, our nonprofit humbly suggests using our website (AnimalHelpNow.org) or our phone app.

The authors downplay the value of helping individual animals and instead regurgitate the tired assertion that conservation is about populations. Yet we all should know the unfortunate truth that a species’ long-term chance of survival usually depends at least to some degree on a human or group of humans ascribing value to it. Welcome to the Anthropocene, Science.
