of the world": not just a changing climate but also the widespread conversion, <br />via urbanization, agricultural intensification and so on, of natural spaces into <br />human ones, with fewer and fewer resources "left over" for nonhuman <br />creatures to live on. What resources remain are often contaminated. Hans de <br />Kroon characterizes the life of many modern insects as trying to survive from <br />one dwindling oasis to the next but with "a desert in between, and at worst <br />it's a poisonous desert." <br />In the United States, scientists recently found the population of monarch <br />butterflies fell by go percent in the last 20 years, a loss of goo million <br />individuals; the rusty -patched bumblebee, which once lived in 28 states, <br />dropped by 87 percent over the same period." -- B. Jarvis <br />7_1 <br />"Prior to its listing as endangered in 2017, the species experienced a widespread and steep decline. The <br />exact cause of the decline is unknown, but evidence suggests a synergistic interaction between an introduced <br />pathogen and exposure to pesticides, specifically insecticides and fungicides, which was also noted in the <br />species assessment. The species status assessment notes that the remaining populations are exposed to <br />several interacting stressors, including pathogens, pesticides, habitat loss and degradation, non-native and <br />managed bees, the effects of climate change and small population biology. These stressors likely operate <br />independently and synergistically. For example, dietary stress due to insufficient floral resources may reduce <br />an individual's resiliency to pathogens and pesticides, exposure to insecticides can reduce resistance to <br />disease and exposure to fungicides can increase insecticide toxicity. <br />"Saving a species from extinction is a group effort, with partners from national conservation organizations <br />and agencies to local communities and citizens, we can't do this alone" said Charlie Wooley, regional director <br />for the Great Lakes Region of the U.S. Fish and Wildlife Service. "This is a great opportunity for those who <br />live in the range of the rusty patched bumble bee to get involved in recovery, whether you live in a rural <br />setting or urban areas where we're finding the species. We encourage everyone to help by learning more <br />about this interesting bee and providing flowers for pollen and nectar. Together we can make sure this <br />important native pollinator doesn't slip away." <br />The final recovery plan for the rusty patched bumble bee includes actions such as land management to <br />improve floral resources and measures to reduce exposure to pesticides and disease -causing pathogens. <br />Raising awareness about the species and engaging private citizens and groups are also key to recovery." <br />- US Fish & Wildlife Service <br />"Ecosystems function locally. And every time you lose a <br />species from your ecosystem, it functions more poorly. <br />Species have the potential to sink or save the ecosystem, depending <br />on the circumstances. Knowing that we must preserve ecosystems <br />with as many of their interacting species as possible defines our <br />challenge in no uncertain terms. It helps us to focus on the <br />ecosystem as an integrated functioning unit, and it deemphasizes the <br />conservation of single species. Surely this more comprehensive <br />approach is the way to go." — Douglas W. Tallamy <br />It is increasingly clear that much <br />of our wildlife will not be able to <br />survive unless food, shelter, and <br />nest sites can be found in suburban <br />habitats. And because it is we who <br />decide which plants will grow in <br />our gardens, the responsibility for <br />our nation's biodiversity lies largely <br />with us. Which animals will make it <br />and which will not? We help make <br />this decision every time It 4 <br />we plant or remove r)r <br />something from AWit <br />our yards. <br />— Doug Tallamy, <br />Bringing Nature Home, zoo7 Og <br />M <br />
