Wildfires are indeed on the rise and the destruction they can cause is indescribable. This somewhat unconventional solution in California will hopefully protect the area from disaster: a family of eight beavers has arrived on the scene in order to fight (or at least prevent) wildfires.
Beavers used to be abundant here and there are even 1,000-year-old pictograms of beavers from the Tule River Tribe. Consulting this old traditional knowledge along with beavers’ well-known propensity to create dams are what lead to this family of beavers being tasked with the very important job of fighting wildfires.
The Return of the Beavers to the Tule River
A family of eight beavers has been reintroduced to the Tule River Reservation in California’s southern Sierra Nevada mountains. This reintroduction is part of a broader effort by the Tule River Tribe and California’s Department of Fish and Wildlife (CDFW) to make the landscape more resilient to droughts and wildfires.
Why Beavers Are Important for Ecosystems
Beavers are known as “ecological engineers” because their dams trap water, slow down its flow, and help to retain moisture in the surrounding environment.
This process not only supports local wildlife but also makes the area more resistant to drought and wildfires, which have become increasingly common.
How Do Beavers’ Teeth Not Break?
Beavers have incredibly strong teeth thanks to a high iron content (most other rodents have magnesium) in their enamel, which gives their teeth an orange color. This iron-rich enamel makes their teeth tougher and more resistant to breakage, even when gnawing through wood.
On top of that, their teeth continuously grow, never stopping throughout their lives.
How Hard Can a Beaver Bite?
A beaver’s bite is remarkably powerful, capable of exerting around 180 pounds of pressure per square inch (PSI). For reference, this is roughly twice the pressure of a human bite.
This strength allows them to cut through trees and branches with ease, enabling them to build their dams and lodges efficiently. Despite their strong bite, beavers are generally non-aggressive (although there are a few reported incidents, but they’re rarely unprovoked.)
Addressing Droughts and Wildfires in California
California has been facing severe droughts and wildfires, with some of the worst incidents occurring in the last five years. The reintroduction of beavers is seen as a natural solution to help manage these challenges by improving water retention and making the landscape more resistant to fire.
Preparing the Land for Beaver Reintroduction
To help the beavers adapt more quickly, the Tule River Tribe has been preparing the area since 2014. Man-made dams were built to create a welcoming environment for the beavers, who are now expected to enhance these efforts by building their own dams and further improving the water retention in the area.
Luckily, these beavers are probably completely unaware of how many are watching them and what great things are expected from them.
What the Pelt Trade Did To Beavers in the U.S.
Before European colonization, North America’s beaver population was around 200 million. However, extensive hunting for their pelts in the 1800s drastically reduced their numbers. Today, the population is estimated to be about 12 million, highlighting the need for restoration efforts like those in California.
Consulting 1,000-year-old Pictures and Traditional Knowledge
The Tule River Tribe has long recognized the importance of beavers in maintaining healthy ecosystems. Tribal pictographs, some as old as 1,000 years, depict beavers living in the area. This traditional knowledge has played a crucial role in guiding the current reintroduction efforts.
California’s Beaver Restoration Program
In 2022, the California Department of Fish and Wildlife launched the Beaver Restoration Program to restore beaver populations across the state. This program aims to support conservation efforts and improve the state’s resilience to climate change, drought, and wildfires through the reintroduction of these keystone species.
Monitoring the Reintroduced Beaver Family
The released beavers, including three adults and four younger animals, are being closely monitored by CDFW wildlife biologists. Early reports indicate that the family has remained together at the release site, showing positive signs of adapting to their new environment on the Tule River Reservation.
Future Plans for Beaver Reintroduction
The initial release of beavers on the Tule River Reservation is just the beginning. The Tule River Tribe and CDFW plan to release more beavers in the coming months and years, with the goal of reestablishing a diverse and sustainable beaver population in the area, contributing to long-term environmental resilience.
Anticipating the Impact of Beaver Dams
As beavers continue to build dams and create wetland areas, the Tule River Tribe expects to see improvements in water quality, habitat conditions for native wildlife, and overall biodiversity. These changes are anticipated to bring lasting benefits to the community and the environment, making the region more resilient to future climate challenges.
