Drones can provide a low-cost, low-impact solution for environmental managers working in a variety of ecosystems.
(H)ealthy, resilient forests actually need fire to thrive.
That concept has been the centerpiece of U.S. forest fire policy for almost two decades now. The 1995 Wildland Fire Policy, which governs firefighting on public lands and wilderness areas, states: “Wildland fire, as a critical natural process, must be reintroduced into the ecosystem.” The policy (which does not, by the way, in any way prohibit fighting fires that threaten life or property) grew out of the modern views of ecologists, who today see that flames are as much a part of a forest as the trees. Firefighting, in the view of many of these ecologists, should focus on protecting homes, watersheds, and critical infrastructure. But blazes in more remote woodlands should be allowed to run their course — a policy that wastes less money on fighting fires that won’t hurt anyone, while making forests healthier overall.
Yet not everyone sees it that way.
Great question and I did a little research for you (learned a lot, so thanks!).
The so-called “sixth extinction” theory has been around for a while. I’d avoid reading about it, since it’s all doom. Still, adaptation strategies for bees and other pollinators are only now being taken seriously.
Keep in mind that environmentalism is ‘stewardship’ - it requires long-term thinking, far beyond your life-time. Solutions take time and decades of research and testing. So, managing impacts are part of a long transition…
Most adaptation strategies and responses are part of bigger plans that deal with ecosystems and agriculture, so they’re more likely to be a chapter in larger documents. Here a few resources:
Hope that helps!
Mangrove conservation is important in the fight against climate change, and not just because mangroves can slow storm surges, prevent erosion and lower disaster risk for coastal communities.
A new book, Novel Ecosystems, edited by Richard Hobbs of the University of Western Australia and others, shows how many superficially natural ecosystems are heavily influenced by the introduction of alien species. Whether intentional or accidental, most introductions seem to have human origins.
This is disconcerting. “Over large parts of the globe, the ‘wilderness’ that people refer back to never existed,” says one of the book’s authors, Michael Perring, also of the University of Western Australia.
Nature has always had open borders for alien species on the move. Those itinerants may have been a driving force of evolution. But human activity has dramatically increased their travel options. We move many deliberately, as commercial crops or domesticated animals, for instance. Today, others can hitch a ride on ship hulls or in ballast tanks, aboard planes or on the wheels of trucks or the backs of domesticated animals. This phenomenon seems to have been going on for much longer than we sometimes imagine.
