The horrible glass fire is threatening our friends at Safari West AGAIN, so if you have any leftover space in your thoughts and prayers please after praying for our constitution. our supreme court and asking to spare members of your family from Covid, please send some metta and loving kindness their way. Fire is very much on our minds in California. Like mercy it droppeth as the gentle rains from heaven. Ash is covering our decks and our gardens and the smell of smoke woke me up.
I’m so glad Rick Lanman updated his wikipedia page.
Beaver ponds as wildlife refugia and firebreaks in wildfires
Beaver and their associated ponds and wetlands may be overlooked as effective wildfire-fighting tools.[145] Eric Collier’s 1959 book, Three Against the Wilderness, provides an early description of a string of beaver ponds serving as a firebreak, saving the home of his pioneer family from a wildfire in interior British Columbia.[146] Reduction of fuel loads by beaver removal of riparian trees, increased moisture content in riparian vegetation by beaver-raised water tables, and water held in beaver ponds all act as barriers to wildfires. In a study of vegetation after five large wildfires in the western United States, riparian corridors within 100 meters of beaver ponds were buffered from wildfires when compared to similar riparian corridors without beaver dams. [147] Professor Joe Wheaton of Utah State University studied the barren landscape left one month after the Sharps Fire burned 65,000 acres (260 km2) in Idaho’s Blaine County in 2018. He found a lone surviving green ribbon of riparian vegetation along Baugh Creek,[148] (see image) illustrating how a string of beaver ponds resists wildfires, creating an “emerald refuge” for wildlife.[145] Lastly, two studies of the Methow River watershed, after the 2014 Carlton Complex Fire burned 256,000 acres (1,040 km2) in north central Washington State, have shown that beaver dams reduced the negative impacts of wildfire on sediment runoff, reduced post-wildfire sediment and nutrient loads, and preserved both plant and macroinvertebrate communities.[149][150]
In addition to citing Emily and Alexis fantastic paper he also came across an outstanding thesis by Edin Stewart entitled: Beavers Buffering Blazes: The Potential Role of Castor canadensis in Mitigating Wildfire Impacts on Stream Ecosystems. I will add the whole paper to our library but suffice it to say it concludes whoppingly with the following sentence: “our study provides support for the hypothesis that beaver dams reduce the negative impacts of wildfire on stream habitats and communities.”
Yup.
Speaking of fire, one of the evacuations I heard on the news yesterday was the Oakmont region of Sonoma. This has been on my mind lately because of the famed Oakmont Symposium which is a dynamic and coveted and widely attended lecture series. I think we met a fellow from the group years ago at the dam watching beavers in Martinez.
So I spent yesterday working on this. Fire notwithstanding, I assume this will happen?
Some say the world will end in fire,
Some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
