So here I am, a beaver advocate, who has resisted reading the most famous beaver story of all time; Hope Ryden’s Lily Pond. Everyone said it was sad and beautiful, and I had enough sad and beautiful right here in my own backyard thank you very much. I will say my curiosity was peaked when I learned that our German beaver friend and foreign correspondent Alex, had sent her a few of my columns. I later learned that Alex had spent a summer working with her and later Sherri Tippie in Colorado. Recently a beaver supporter sat me down with an original signed copy and insisted I read a little.
I’m so glad she did!
I am slowly savoring the earliest chapters, but I had no idea it was so science-thoughtful. It’s like reading Gorilla’s in the Mist or Never Cry Wolf. As the story opens she has obtained a permit from the Ranger to study a local colony in New York. She is waiting silently for a glimpse of a beaver, patient for hours, days, longer. Then sees a large beaver she calls the “Inspector General” who comes out at the same time every night to check the dams. At first he is the only beaver than can tolerate her approach and allow her to get closer.
It’s wonderful to watch her learn things that we have learned by accident, but I was most excited by her use of night photography. She was trying to take pictures without disruption and painstakingly used red lights and strobe lights so the beavers wouldn’t be upset by the light. (!) Then an accident happened and she turned light upon them, and lo! the beavers were unphased! and she learned that beavers have no Eye Shine!
In this moment she realized what we’ve long realized. When you shine a light in a beavers eyes there is no reflection. Nocturnal animals like raccoon, bobcat, deer and possum have light gathering crystals called tapetum lucidum. They evolved this ability to help them manage life at night. Hope wondered why beavers didn’t have it? Could it be that the species is too newly adapted to night life to have evolved the trait?
She did the work I admire and went searching through historic records. Early trappers often mention beavers out during the daytime, and even “Sunning themselves on their lodges“. She writes
If these descriptions can be believed, they raise another question: what would cause a diurnal species to become a nocturnal one? Could such a change have come about as a result of the extraordinary trappping pressure exerted on the beaver over three centuries?
Hope Ryden, The Lily Pond pg 45
She goes on to convincingly describe the horrific “beaver ethic cleansing” that was perpetrated by the Dutch, the Canadians, the French, and the Native Americans in service for all of the above. The market was already hurting because the European Beaver had been trapped to extinction in the 1600’s. So it was wonderful to find a new source for pelts and castoreum. There were no restrictions at all placed on the number of beaver. At the end of the 18th century there were so many beaver pelts on the market that 75% of the pelts taken were burned to hold the price of fur at a profitable margin. In fact, in 1811 John Jacob Astor’s fur trading post had taken all the beaver from Oregon and systematically removed every them from every last tributary in the Columbia River. By the time of the invention of the steel-jawed leg hold trap in the 1840’s, there weren’t many beaver left to trap.
In 1895, fourteen states announced they had no beavers at all. Not one. These included Massachusetts (where Beaver Solutions is located) Vermont (where Skip Lisle is located!), New Hampshire, Rhode Island, Connecticut, Pennsylvania, New Jersey, delaware, Maryland, Illinois, Indiana, Ohio, West Virginia, and Florida.
One can speculate that the few animals that escaped this continent-wide decimation must have been the wariest of their kind, deviants, disinclined to build conspicuous lodges. And inded, the late ninteeth-century reports of sightings describe the beaver as a reclusive bank-dweller. One can also speculate that these survivors escaped the notice of trappers by turning night into day, for by the end of the last century, no further mention is made of beavers “sunning themselves on their lodges”.

Okay, I know I’m a huge beaver nerd, but that’s FASCINATING. It makes so much sense to think of bank lodges as an adaption to hunting, and beavers being nocturnal out of necessity and not out of genetics. The book was written in 1989 and I haven’t yet heard what beaver-ologists like Muller-Swarze or Baker think about it, but you can be I’ll be asking them.
In the meantime, you can pick up your own used copy of Lily Pond from Amazon, and follow along at home. I am sure I’ll have more revelations soon.
