Fighting fire with beavers: How dam-building rodents are deployed to prevent megafires, restore scorched wildlands

There used to be a time when oil spills devastated entire populations of animals. Although still an environmental disaster, scientists and wildlife veterinarians have become profoundly more successful at treating oiled birds. Crediting much of the success to better understanding the importance of order of treatment, rehabilitated birds are surviving at a much higher rate than ever before.

In California’s wildfire-prone Sierras, forest managers are turning to an ancient, if not quite intuitive, tool: more fire. In 2019, the Forest Service will manage 250,000 acres with controlled burns and “mechanical thinning,” using equipment to take out small trees. Though such plans face some hurdles, states across the country are adopting them, reducing wildfire severity while often benefiting ecosystems.

In the wake of more than 100 forest fires in Maule, Chile, hundreds of burned acres of forest are being replanted by three Border Collies named Das, Olivia, and Summer and an organization called Pewos. The dogs bound through miles of terrain with special backpacks that release native seeds to regrow the area. So far the dogs have worked in 15 forests in the region and plants are starting to come back.

In Londonderry, New Hampshire, the Carriage Shack Farm hire out goats to eat unwanted plants like poison ivy or bittersweet. Contrary to humans, they aren’t harmed by the plant and actually enjoy eating it. Prior to being hired, the farm trains the goats so that their appetites and stomachs aren’t adversely affected.

In Indonesia, transferring land management rights to local residents is slow-going, but one community is setting an example for what can happen when the residents are in charge. Mandiri farmers formed a cooperative and began replacing hillsides; now, tourism to the area has increased and attitudes towards the land and community have changed.

For years, a rancher in Southern Oregon has been trying to keep a local pack of wolves from killing his livestock, and after many rounds of trial and error and collaborative efforts, a high-tech fence may be the solution. Although the fence isn't cheap, many came forward to help make this a possibility and show their support for a project that united people that historically have stood politically opposed.

Local Ocean Conservation is in Watamu, Kenya has made approximately 21,000 turtle rescues and "treated more than 650 turtles in its rehabilitation center and clinic" since it's inception in 1997. The group responds to fishermen who have accidentally caught turtles in their nets and then remunerates the fishermen for their "time, effort, and phone calls." This incentive-based relationship combined with a ban on the international tortoiseshell trade has helped decrease the poaching of turles, and the group has now expanded their efforts to include more initiatives to protect the endangered species.

Beavers and the dams they build have been found to be tools against climate change as the planet’s temperature continues to rise. Dams slow water down and allow it to seep into the Earth, providing groundwater for humans, and also cools down both water and air temperatures. Beaver dams also create wetland ecosystems that are practically resistant to wildfires.

Two nonprofits came together to manage Hawai'i's Kaua‘i’s Hā‘ena State Park in a community-led way, creating a more equitable relationship between the tourism industry and the local community. Native Hawaiians work at the park, lead restoration projects and run educational programs. And to prevent overtourism, tourists must make reservations and pay to enter.

A locally-owned wood lot in Oakridge, Oregon, collects piles of debris from the surrounding forest that could become fuel for wildfires and turns it into firewood for the community. Alongside wildfire mitigation, the business reduces the air pollution residents create when their only option is to burn wet wood for heat.
