Hello! I’m Catrin. I cover biodiversity for the Climate and Environment team here at The Times. Sometimes people forget that latter part of our name, with so much focus these days on climate change. But we cover all kinds of environmental issues. Plus, the climate and biodiversity crises are deeply linked, and scientists say they must be addressed together. The people behind Climate Forward invited me to make a guest appearance today to offer a new take on one of my recent articles, which looked at why some states can’t protect insects. That lack of authority is a problem for at least two reasons: First, many insect species show alarming declines. Second, the rest of terrestrial life on this planet, including humans, relies on insects. Creatures like bees , butterflies and beetles pollinate plants, enrich soil and provide a critical source of protein for other species up the food chain. Still, when it comes to insect conservation, at least a dozen states have their hands tied, legally spea king. The article I wrote focused on that. But it’s not just insects and other creepy-crawlies, like spiders and centipedes, that get left out. In some states, authority over plants (not to mention fungi) is murky or nonexistent, according to Mark Humpert, director of conservation initiatives at the Association of Fish and Wildlife Agencies. Why it mattersPlants make the rest of us possible. In the words of Doug Tallamy, an entomologist at the University of Delaware, they “allow us, and nearly every other species, to eat sunlight, by creating the nourishment that drives food webs on this planet.”They let us eat sunlight! Also, since plants and insects often have highly specialized relationships, the extinction of a certain plant species can create a cascade of other extinctions. Which leads to another important idea: The approach to conservation that has brought back charismatic megafauna like elk and bald eagles doesn’t always work so well for the multitude of species closer to the bottom of the food web. “The single species, one-at-a-time approach doesn’t make sense for insects because there’s so many of them,” Matt Forister, an insect ecologist at the University of Nevada, Reno, told me. A shift has started, state wildlife workers said, but there’s a long way to go. And they noted that a lack of attention to insects and plants can even end up undermining efforts to protect animals higher up the food chain. Take the greater sage grouse , an at-risk bird that lives in the sagebrush steppe of the West. After wildfires, restoration efforts involve planting lots of sagebrush, which the birds need to nest in and eat. But for the first several weeks of their lives, sagebrush chicks require high-protein insects. To attract a diversity of insects, you need a diversity of native plants. Planting sagebrush monocultures doesn’t cut it.”We need to understand the needs of all the species that are a part of the system, that are all contributing to each other,” said Ross Winton, an inve rtebrate biologist at the Texas Parks and Wildlife Department. “Instead of managing for the species at the top of food chain, we need to understand the relationships between them.” What you can doGreater sage grouse aren’t the only bug-loving baby birds Dr. Tallamy has estimated that about 96 percent of North American terrestrial birds rear their chicks in part or exclusively on insects. So, he and others are behind a growing movement to support ecosystems by encouraging people across the country (and beyond) to plant native flowers, grasses, shrubs and trees. It’s a way to support the things at the bottom of the food web, one yard or rooftop garden at a time. Need a place to start? The National Wildlife Federation has worked with Dr. Tallamy on a handy tool. If you’re looking to help the bugs that help us, planting food for them is a great start. Essential news from The TimesA landmark deal to protect oceans: Nations have agreed on language for a treaty to protect marine life in the high h seas, the international waters that cover almost half the planet.

He’ll focus on links between development solutions and climate.US sues Exxon: Federal officials said in a suit that the oil and gas company has failed to remedy years of racial harassment faced by Black workers. Trees cheating death: Climate change has left much of California’s conifer forests stranded in habitats that no m, longer suit the a study found. They are considered “zombie” forests. No ice, no fun: Ice fishing season is the best time of the year for some residents of an Ohio island on Lake Erie. But this winter, the lake didn’t freeze.
