Fires and floods are the punishing destructive forces of nature that even the bible recognizes. The answer to both might be staring us in the face. What if what we needed all along wasn’t an ark, but a some beavers? 
The National Trust is preparing to release a small number of beavers into the south of England to help manage the landscape and combat flooding.
In a scheme to combat flooding, the National Trust is planning to release a small number of beavers in England. Initially, two pairs of beavers will be released into large woodland enclosures in Holnicote, Somerset, near tributaries to the River Aller. A third pair of beavers will be released into an enclosure at Valewood, on the edge of the South Downs, West Sussex.
Beavers, once native to Britain, were hunted to extinction in the 1500s, although small numbers have been observed in the wild in Scotland and Devon in recent years. Beavers are considered a ‘keystone’ species due to their work building dams in rivers, which significantly affects the landscape and ecosystem around them. Through dam building, beavers help restore precious wetlands through erosion reduction, downstream flood control and water cleansing. However, scientists have also raised concerns about the volumes of carbon being released into the atmosphere from soil as a result of beaver damming.
That’s right. Beavers to the rescue. Again. Although no solution is without its risks. Noah might deserve full disclosure.
“Beavers are nature’s engineers and can create remarkable wetland habitats that benefit a host of species, including water voles, wildfowl, craneflies, water beetles and dragonflies,” said David Elliot, National Trust lead ranger for Valewood. “These in turn help support breeding fish and insect-eating birds such as spotted flycatchers.”
Well said.
Yes they do. And if prevent flooding’s not enough, maybe you’ll be interested to know they can also reduce the risk of fire.
Don’t believe me? Ask a scientist.
Smokey the Beaver: Can Beaver Dams Help Protect Riparian Vegetation During Wildfire?
When beavers move onto a creek, they build dams that slow the flow of water and spread it out over the landscape. That stored water can help keep the entire landscape wet and lush, even when everywhere else is dry. People have seen beaver-dammed areas stay green through droughts before, and this past year photographs of green beaver wetlands surrounded by the char of wildfire showed up in the news media. Although we are seeing this happen, there weren’t any studies proving that places with beaver damming are burned less by wildfires than places without beaver damming. We looked at five different large wildfires that burned in places with beavers, and use satellite data of plant greenness to see whether or not the plants actually stayed green and healthy during the fires if they were near beaver dams. Our data confirms what people had already seen happening: places with beaver stay green even during wildfires, places without beavers do not. For a short (45-second) animation of this phenomenon,
Wow! December 11 in San Francisco. That would be our own heroine Emily Fairfax who wowed the world with her smart research and stop motion film last year. Emily started work as an assistant professor at Cal State Channel Islands and if she keeps this up I’m expecting great things for her and beavers.
