“The restoration of ecosystems is an important avenue to mitigate the risk of wildfires before they occur and to build back better in their aftermath. Wetlands restoration and the reintroduction of species such as beavers, peatlands restoration, building at a distance from vegetation and preserving open space buffers are some examples of the essential investments into prevention, preparedness and recovery.”https://www.unep.org/news-and-stories/press-release/number-wildfires-rise-50-2100-and-governments-are-not-prepared
– “California’s water problems are intense; so much so they are often referred to as ‘wicked’ for their extraordinary depth of complexity and general unsolvability. Yet it recently occurred to me that some of the better and more creative solutions often derive from one particular source – nature itself. Indeed, studies of nature-based solutions or ‘NBS’ are rising rapidly (Davies and Lafortezza 2019; Nelson et al. 2020; Acreman et al. 2021), and are especially popular within the NGO and environmental communities. This blog is a brief exploration of the concept, examples of nature-based solutions, both for California water and also generally, and why they might matter to us.” https://californiawaterblog.com/2022/03/27/nature-has-solutions-what-are-they-and-why-do-they-matte
– “Rivers and streams, when fully connected to their floodplains, are naturally resilient systems that are increasingly part of the conversation on nature-based climate solutions. Reconnecting waterways to their floodplains improves water quality and quantity, supports biodiversity and sensitive species conservation, increases flood, drought and fire resiliency, and bolsters carbon sequestration. But, while the importance of river restoration is clear, beaver-based restoration—for example, strategic coexistence, relocation, and mimicry—remains an underutilized strategy despite ample data demonstrating its efficacy. Climate-driven disturbances are actively pushing streams into increasingly degraded states, and the window of opportunity for restoration will not stay open forever. Therefore, now is the perfect time to apply the science of beaver-based low-tech process-based stream restoration to support building climate resilience across the landscape. Not every stream will be a good candidate for beaver-based restoration, but we have the tools to know which ones are. Let us use them.”https://wires.onlinelibrary.wiley.com/doi/10.1002/wat2.1592
– “Beavers build dams, dig channels, and change small streams into broad wetland areas. Their ponds and channels in particular slow down water and spread it out in the landscape. This gives that water more time to soak into the soil, which ultimately keeps plants green and lush even during periods of drought. The channels the beavers dig almost act like a little drip irrigation system running throughout the entire riparian zone.”https://emilyfairfaxscience.com/research/droughtbeavers
– “Beavers build dams, dig channels, and change small streams into broad wetland areas. This keeps plants green and lush, even during periods of drought. When a fire ignites, that green vegetation near the beaver ponds will be more difficult to burn than other nearby dry vegetation. The fire will often take the path of least resistance and burn through the dry vegetation away from beaver ponds instead of smoldering through the wet vegetation near beaver ponds.”https://emilyfairfaxscience.com/research/firebeavers

– Shallow open water wetlands provide critical habitat for numerous species, yet they have become increasingly vulnerable to drought and warming temperatures and are often reduced in size and depth or disappear during drought. We examined how temperature, precipitation and beaver (Castor canadensis) activity influenced the area of open water in wetlands over a 54-year period in the mixed-wood boreal region of east-central Alberta, Canada…https://www.sciencedirect.com/science/article/abs/pii/S0006320707004557
