Beavers Reintroduced to Greenford, England, to Combat Climate Change

A family of five beavers, consisting of two adults and three kits, was released into the 20-acre Paradise Fields nature reserve in Greenford, England, on October 11, 2023. This release marked the first presence of beavers in West London in 400 years. The effort is part of the Ealing Beaver Project, aimed at helping Britain adapt to climate change-related challenges.

West London’s Greenford Tube station often flooded during heavy rains. Despite the train tracks being aboveground, its ticket office would frequently get inundated. To address this issue, a family of beavers was introduced to a nearby area, which helped create a pond and a wetland that mitigated flooding.

Beavers are integral to an endeavor to reintroduce a vanished species and tackle climate change’s impact. Increased rainfall and flooding are now common due to climate change, prompting conservationists to collaborate with beavers, renowned for their dam-building capabilities.

Conservationists obtained a government license to relocate the beavers to an urban park near Greenford Tube Station. It was previously a golf course with a creek. Within weeks, the beavers created a water-holding pond, stopping it from flooding the city. They diverted the creek into smaller tributaries, forming a wetland that efficiently absorbs rainfall and reduces flooding risk.

“They effectively turned this site into a giant sponge that can take heavy rainfall and slowly release water back into the landscape, creating a lot more resilience for flooding,” explained Sean McCormack, a veterinarian who initiated the Ealing Beaver Project.

The beavers also enhanced local biodiversity. By felling trees and opening the canopy, species like freshwater shrimp, eight bird species, and two types of bats returned. Rare brown hairstreak butterflies, favoring blackthorn branches, also made a comeback. Their resurgence allowed officials to halt expensive reservoir plans, recognizing beavers as cost-effective and sustainable partners.

Inevitably, the presence of beavers attracts visitors. The Paradise Fields reserve offers hiking paths, guided walks, and beaver safaris, drawing both locals and tourists to observe the beavers’ activities.

Reintroducing beavers to Britain began in 2009 when two Norwegian beavers, genetically similar to Britain’s historical beavers, were relocated to Knapdale Forest in Scotland. Named Millie and Bjornar, these beavers formed the foundation of the modern British beaver population. Tracking their work through hidden cameras, they quickly created habitats benefiting local wildlife and maintaining water presence amidst changing climate conditions.

However, challenges arose as beavers spread to private land, raising concerns among farmers. Their dam-building can inadvertently flood crops and fell trees, causing erosion. Farmers in Scotland face obstacles with expanding beaver populations on their lands and resort to licenses for removal. The Scottish government set up a fund to address riverbank restoration, focusing on public interest repairs.

Nevertheless, some farmers embraced beaver benefits. Tom Bowser, in central Scotland, values them for creating flood-diverting ponds. Bowser initiated beaver-watching tours, drawing visitors and generating interest among children who previously fantasized about beavers.

Beavers continue gaining popularity for land managers short on staff. South Norwood Country Park anticipates their potential benefits, hoping for increased biodiversity and natural water management solutions. Beavers have become crucial allies in sustaining wetlands and reversing declining bird populations.
