This Is How It Goes–
Up north, in the U.P. where my mother lives, folks are getting Lyme disease. These are hearty, out-doorsy people, who spend a lot of time in the woods. Lyme disease isn’t new—it’s been around for decades, just not up there. It’ll take a little time for people to wise up to the new reality—the ticks have moved north. Soon, folks will take precautions, recognize symptoms, and will have made the adjustment so that a bite doesn’t necessarily mean a long-term, debilitating illness. You adjust.
In Michigan, (and southwest Ontario) the forests have been devastated. A shipment from China apparently, and inadvertently, imported the Emerald Ash Borer. It’s a pretty, little bug. Here, we have plenty of ash trees, and no predators. Estimates are that, so far, 20 million trees have been infected and died. There is no cure—they offer some heavy-duty, toxic treatments that can hold it at bay, (if your favorite yard tree is at risk) but nothing can be done to protect the forests. Before it runs its course, we will lose about 80 million trees. Now that the seasonal leaves are gone, you can look into the woods, as you drive by, and see all the fallen trees. It’s heartbreaking. Ash naturally grows in a diverse forest—so there are still plenty of other trees standing but, like the elm before, this area can kiss its ash good-bye.
We have forested property. We walk its hills, shaking our heads. The ash are dying and falling. The tree has a distinctive bark, so even in the winter it’s easy to identify. As we walk, we see not only the downed victims of the blight, but every one of those standing trees, with that lovely deeply-grooved bark, is doomed. They say to expect 100% losses. There are timber restrictions on the movement of ash wood-products. Areas are quarantined to try and prevent the spread. Our quarantine area is Lower Michigan. It’s spread to some counties in the U.P. now, too. So far as I can figure, the only winners in this game, and it’ll be short term, are the woodpeckers, who eat the larvae.
Bat White-Nose Syndrome is spreading across North America. It’s caused by a fungus. In some bat populations, the mortality is 95%. Because it affects a wild species, and the primary transmission route is bat-to bat, there’s not much that can be done. It originated in Europe. Nobody knows how it arrived here, but human transmission is likely. The fungus can be transported by the movement of people and equipment, in the forest. That’s the likely way that it got here. Unlike the European bats, ours have no immunity to the disease. It thrives in cold temperatures, infecting bats during hibernation. Unfortunately, the close contact of bats cuddling in hibernation, speeds its transmission. People shrug. Too bad about the bats, eh? Well, it’s more serious than that. The bats eat the bugs. What are we going to do with the resulting bumper crop of bugs?
Dutch Elm, West Nile, Lyme disease, Emerald Borers, White-Nose. I could go on. (Don’t even get me started about the bees, who are primarily the victims of neonicitinoid pesticides.) These are pests that are spread beyond their borders by the impact of people. In some cases, it is simple relocation, like our Ash Borer. In others, because our climate is changing and so extending the range of existing critters.
Maybe, like Lyme in Northern Michigan, we can adjust to new threats. What about the bats, or the bees, or the ash trees? How will we adjust to a world without bats? What will we do with the resulting bonanza of bugs? More poisons like neonicitinoids? How can we know the rippling impact of these changes? It threatens to change the face of nature. Most Americans don’t live in nature and they won’t notice. They get their food—sprayed, plastic-wrapped and GMO’d. They fail to comprehend that diversity is a necessary component of a healthy environment and take no notice of the rapid level of extinctions all around us. Most Americans don’t know we have a bat crisis, or that the Ash trees are dying.
For my part, next spring I’ll put up bat houses and maybe purple martin condos. I’ll shun chemical interventions and try to live lightly on the planet. I’ll read and try to stay informed. Because this is how it goes.
