Because the beaver isn't just an animal; it's an ecosystem!

Month: December 2019


The creator of the wonderful image is Catrin Welz-Stein of Germany who is an alarmingly talented graphic artist that creates digital collages. Doesn’t it make you want to look at things more closely? Good. I added Amelia’s awesome hobo-beaver and the headline because I wanted to use the image in our activity for the festival. It seemed like destiny that the beavers kit-sack matches she-sherlocks cl0ak. Isn’t that just a marriage made in heaven?

Destiny also released this study in time for my grant writing. How unbelievably lucky am I that this meta-analysis came out with exactly the right results?

Nature May Boost Learning Via Direct Effects on Learners

Kuo M, Barnes M and Jordan C (2019) Do Experiences With Nature Promote Learning? Converging Evidence of a Cause-and-Effect Relationship. Front. Psychol. 10:305. doi: 10.3389/fpsyg.2019.00305

What emerged from this critical review was a coherent narrative: experiences with nature do promote children’s academic learning and seem to promote children’s development as persons and as environmental stewards – and at least eight distinct pathways plausibly contribute to these outcomes. Below, we discuss the evidence for each of the eight pathways and then the evidence tying nature to learning, personal development, and the development of stewardship.

This entire study was so wonderful you should really go read the whole thing. Very well laid out and a summary of the 8 learning paths that change in contact with nature. A paragraph on cause and effect towards the end had me in tears. I swear.

And second, spending time in nature appears to grow environmental stewards. Adults who care strongly for nature commonly attribute their caring to time, and particularly play, in nature as children – and a diverse body of studies backs them up (for review, see Chawla and Derr, 2012). Interestingly, the key ingredient in childhood nature experiences that leads to adult stewardship behavior does not seem to be conservation knowledge (knowledge of how and why to conserve). Although knowledge of how and why to conserve, which could presumably be taught in a classroom setting, has typically been assumed to drive stewardship behavior, it is relatively unimportant in predicting conservation behavior (Otto and Pensini, 2017). By contrast, an emotional connection to nature, which may be more difficult to acquire in a classroom, is a powerful predictor of children’s conservation behavior, explaining 69% of the variance (Otto and Pensini, 2017). Indeed, environmental attitudes may foster the acquisition of environmental knowledge (Fremery and Bogner, 2014) rather than vice versa. As spending time in nature fosters an emotional connection to nature and, in turn, conservation attitudes and behavior, direct contact with nature may be the most effective way to grow environmental stewards (Lekies et al., 2015).

Read that again, will you? Contact with nature drives learning about nature which in turn fosters stewardship. It isn’t lectures about biology, but outdoor positive experiences – like beaver festivals and watching beavers themselves, for example – that drive children to later care for the environment.

We care about what we know. Not ‘know’ like books. But ‘know’ as in play in, discover in, spend joyful time in – breathe in.


Beavers, as it turns out,  are good for plenty of things. For cities and for salmon and for nitrogen removal. Some days we even get to read about it. Enjoy.

Guess what’s in the last page of the city magazine on outdoor things to do in Napa? I’ll give you a hint, It’s not wine tasting.

Remember when the city of Martinez placed the beavers on the city Marquis downtown? It was a horrible comical drawing but it was I think the first time they used the beavers as an  asset instead of a burden. Things change,

Low rainfall during November contributes to smaller salmon runs

Salmon managers are reporting dismal returns of chum and coho salmon to Puget Sound streams this fall, and a sparsity of rainfall during November could result in low salmon survival during the next generation.

Overall, the low rainfall was detrimental to the salmon, which ended up spawning in the lower portion of streams where flows are higher. But Jon Oleyar observed a few positive features this year, such as beaver dams on Chico Creek — the largest producer of chum salmon on the Kitsap Peninsula.

Although beaver dams can impede the movement of chum during low flows, they also can hold back water during high flows, reducing the risk of extreme currents that can scour salmon eggs out of the gravel.

“In the Chico system, we had about 10,000 fish total, and 95 percent of them spawned below river mile 1.5,” Jon said.

That means most chum and even coho spawned this year in the mainstem of Chico Creek, with very few fish getting to Lost or Wildcat creeks. Those tributaries of Chico Creek normally support large numbers of juvenile chum and coho.

“The only saving grace that I can point to is the beaver dams,” Jon said. “In bad weather, the dams can hold back the water instead of having it shoot downstream like a fire hose.”

You’re welcome. I’m sure the beavers would tell you it’s easy being saving salmon. Anyone could do it if they tried. Yes, they don’t blush from all that praise,

On an English Estate, Reintroduced Beavers Might Make a Damn Difference

The future residents of the Holnicote Estate, which sprawls across a portion of Exmoor National Park in Somerset, England, are two families with dark eyes, strong teeth, and thick brown fur. As they settle in in early 2020, these new tenants—mums, dads, and probably a couple of kids—will go about making the place their own.

The beavers are being moved in by the National Trust as part of an effort to reduce flooding and ramp up biodiversity. They’re one branch of a multiyear river restoration project, which is slated The hope is that the beavers, by doing what beavers do, will decrease flooding, limit erosion, and improve water quality. Drone footage, time-lapse photography, and water-quality monitors will be used to help researchers gauge whether it’s working.to wrap in 2024 and also includes bioswales (vegetated channels for runoff), ditches, and more.

Beavers moved into West Devon in 2011 quickly constructed 13 dams along a narrow stream. “The beavers have transformed this little trickle of a stream into a remarkable, primeval wetland,” Mark Elliott, lead beaver project officer of Devon Wildlife Trust, told The Guardian. When beavers do overstep their bounds, Eardley says, it’s easy enough to nudge them along or discourage them from building dams, rather than resorting to lethal measures.

This lovely article even mentions Carol Johnson and Ben Goldfarb’s writing! Which is nice to see in a news story. Bonus points for quoting some old english about the engineers.

“The creatures, “all hearie saving the tail, which is like a fish taile, as broad as a man’s hand,” built themselves great wooden “castells,” 

Indeed, They built castles alright. Castles made by their own labor that fed and housed an entire community for miles upstream and miles downstream. Beavers didn’t take surfs, They did the work themselves.

They are much better than “castells”


It’s impeachment o’clock. So Beavers think I should pay attention and I will share the new application for this summers project.

Nature Detectives: The Case of the Missing Salmon

Nature finds a way of avoiding us. Whether it’s a fox crossing the road in the wee hours or squirrels making their commute on telephone wires, urban nature works hard to stay out of our path.  It can be difficult for children to catch a glimpse of what is going on all around them. Research confirms that a positive experience with nature in childhood is more important to future stewardship than a wealth of biology lessons or academic lectures[1]. Such opportunities are associated with  intrinsic learning, social connections and lower stress levels. We are less likely to understand what we don’t see.

Teaching children to look for the clues our wild neighbors leave (rather than the animals themselves) is a great way to get around barriers. Looking for scat, pellets or footprints can teach children about the unseen residents of their lives and make them keen observers of the natural world. Learning about the complex ecological systems at a beaver pond helps introduce species interdependence.  “The case of the Missing Salmon” will invite children to become ‘nature detectives’ and solve a mystery at a beaver pond, learning to identify the habits and tracks of various riparian wildlife.

The beaver pond makes an ideal setting for the ‘Mystery’ since it supports so many other visitors (suspects) and is an ecosystem unto itself. In particular, this project  reminds participants (and their parents) of the important role such ponds play in the lives of salmon, as well as helping them think through the natural habits of visitors to the pond. Did the salmon become supper for the blue heron or the river otter? Or is there another explanation for its disappearance? Solving the mystery will require learning to identify the tracks  of frequent pond visitors as well as gaining a better understanding of their lifecycles. This will help children attune to detail, think critically and become better citizen scientists in their future dealings with nature.

The Case of the Missing Salmon  will provide a fun way to learn about the essential benefits of a beaver pond using a playful  ‘mystery’ theme. Participants will be the first 100 children attending the 13th annual Beaver Festival in Martinez, CA on June 28th, 2020. Last year this event had an  attendance of 1000, with over 50 participating environmental groups and 100 children finishing the activity. To begin, children will receive an envelope containing a “top secret suspect list” that includes footprints of the 6 likely culprits at the pond. They will be instructed to solve the crime and then return to the beginning to report their  answer and collect their prize. To do this they will visit participating displays representing those six species and learn about them to collect a clue. These clues can be combined to rule out suspects and learn the ‘solution’ to the mystery. (The missing salmon swam to sea.)  

Participating groups will be designated on the map and by a sign at the booth  showing the animals and its tracks. When a child successfully matches the track card with a species they will be given an  alibi card, showing the animal, its track and its innocence. On the back will be a part of a sentence giving the solution. When all six cards are collected, children will be helped to combine them and learn the answer. They can then return to the beginning and collect their prize for solving the mystery: an ornamental magnifying glass they can keep. They will then be invited to take a post quiz matching the tracks they have recently learned with the wildlife species in question.

Exhibitors  will be selected for their knowledge of the topic and willingness to participate. They will be considered ‘sponsors’ of the activity. Sponsor stations will be designated with a sign showing the animal and its tracks. “Alibi” cards and signs will be distributed to sponsors on the morning of the festival by the California Core Watershed Steward Interns, Arianna Topbjerg and Ellen Mills, who will also review the activity with exhibitors.

Amy G. Hall  will be simultaneously illustrating  a 10 foot square in the plaza with chalk the day before and day of the festival –  showing the beaver pond and the wildlife it sustains. Amy is an award-winning street and graphic artist from Napa with a special interest in beavers. Even though she typically receives $1000 a day for similar commissions, she enjoyed her participation so much last year that she has agreed to do this two-day piece without fee provided Worth A Dam pays for needed materials. Susana Park is an ideal venue for this event, and provides an excellent way for exhibitors to spread comfortably around the focal point of Amy’s artwork. Children will be encouraged to draw their own illustrations in the plaza margin, so that by the end of the event attendees will be surrounded by beaver ponds at every level.

After solving the mystery,  participants will be invited to complete a short quiz about what they learned in order to gauge activity effectiveness. We have found that parents enjoy seeing what their children remember, and it’s not uncommon for kids to correct their parents proudly during this period. Completed surveys will be raffled for prizes awarded after the festival to assure maximum participation. (We have found a beaver kit puppet makes a great motivator in getting kids eager to complete post quiz!) Results will be analyzed along with sponsor and parent feedback to fine-tune next year’s activity.

Sometimes headline is all you need to make you very, very happy. Like this one for instance.

How Dangerous Is the Beaver?

Even if that was all there was, Just an inflammatory headline and a great photo, it would be enough to amuse me with endless Monty Python scenarios. Imagine how lucky I felt when the article continued?

With their oversized front teeth, beady little eyes and funny flat tails, beavers look less like crazed killers and more like the goofballs of the woods. Yet with their distinctive orange-colored incisors, these furry wonders can slash through a finger-sized tree branch with just a single chomp. So that begs the question: Are beavers dangerous to humans?

Oh my goodness. Get me the popcorn. This is going to be good.

It turns out that yes, in certain circumstances, beavers might harm people and pets.

Of course they go on to describe Belarus because they’ll never live that down. But I was especially pleased to see this:

Do Beavers Help or Hurt the Environment?

The results are often a win-win for both beavers and other creatures. “Beavers are tremendously beneficial to the environment. They are North American ‘keystone species‘ meaning their presence on the landscape increases biodiversity,” says Callahan. “Beavers build dams to turn streams into ponds. The new habitats created support innumerable plant, insect, fish and animal species, including salmon and other endangered species.”

He also says that beaver ponds also help fight climate change and wildfires, store precious water and recharge ground water aquifers, improve water quality by removing pollutants from the water, and fix eroded stream channels and restore healthy watersheds. “And beavers perform all these valuable ecosystem services for free!” he adds.

Hurray! Mike! Well done and what a great place to find a friendly face.  Gee how do you get interviewed for “How stuff Works?”. What do they even say when they call? I’m a reporter from google? Or maybe they just email? I wanna play!
 
I actually love how the article ends, too.
Well that was more fun than I ever expected. And it ended up in the right place which I never get tired of.
I just have to do one Monty Python, because its necessary.

Just one more perfect headline to share before I go.  This one from the Ellwood City Ledger in Pittsburg. And this one is for the scrapbook.

Impeachment rally planned for Beaver the day before House vote is expected

Gosh. I know rule of law is pretty important to beavers. But I never expected this.


I’m going to make you all cry now.  Well not me, Patti Smith. The Vermont “me” – way more graceful and without the sarcasm. She’s going to make you cry with this beautiful column about the death of her heroic ambassador beaver, Willow. You’ll know, when you read her elegiac prose, how much I thought of the death of our own mother beaver loo, lo, these nine years ago. It takes the courage of a matriarch to change a woman’s life apparently. Mom was the one who decided to live near us in Martinez. And Willow was the first that allowed her life to be touched by Patti. My heart grieves for her loss, and ours.

On the night of December 3, I broke a trail through the deep fresh snow to the shores of Sodom Pond. It was not the tough, uphill work that made me immune to the beauty of the moonlit forest; I was going to say good-bye to my old friend Willow.

Some of you met Willow when I began writing about her in this column nearly twelve years ago. If so, you will know that she was the first volunteer when I decided I would like to meet a beaver. She has been sharing her life with me (and you?) ever since. This fall found her settled in a new pond with Henry, mate number five, and Gentian, their 18-month-old kit.

Willow’s life was remarkable on two counts. As a beaver ambassador, she welcomed many visitors over the years. In this capacity, she played a small role in awakening humanity to the tremendous role beavers play in making habitat and in holding cooling water on a heating planet.

Willow also had an unusually long life. I have speculated about the superpowers that kept her alive while so many other beavers disappeared. She has been blind in one eye for the past five years and has had the disheveled, bony appearance of advanced age for nearly as long. I suspect she was close to the maximum age for a beaver. The record for a beaver in captivity is 23 years. Beavers in the wild seldom attain half that age.

I wish I could say something that would soften this article for you. But I can’t. All I can do is remember this, the night after we lost mom and my long sniffling watch to see if her kits were cared for, I filmed these the night after mom died.

[wonderplugin_video iframe=”https://youtu.be/fh6MutjI96Y” lightbox=0 lightboxsize=1 lightboxwidth=960 lightboxheight=540 autoopen=0 autoopendelay=0 autoclose=0 lightboxtitle=”” lightboxgroup=”” lightboxshownavigation=0 showimage=”” lightboxoptions=”” videowidth=600 videoheight=400 keepaspectratio=1 autoplay=0 loop=0 videocss=”position:relative;display:block;background-color:#000;overflow:hidden;max-width:100%;margin:0 auto;” playbutton=”https://www.martinezbeavers.org/wordpress/wp-content/plugins/wonderplugin-video-embed/engine/playvideo-64-64-0.png”]

In late November, after the first snow of the year, I heard a beaver’s tail slap warning when I arrived at the pond. Henry made a brief, nervous appearance but swam away again. Willow did not show up. I tried not to worry, but Henry’s anxiety was contagious.

The next night, I headed to the pond again hopeful that I would find the wayward beaver and prepared to search if I did not. Only Henry came when I called. I wandered downstream to previous ponds and back on the far side of the brook. I found no recent sign of Willow, but many reminders of the hours spent on those shores. When I arrived at the far side of their home pond, I could see young Gentian out on the ice processing a tree they had felled. From that vantage, I also saw the tracks of a bear. The bear had walked across the slushy surface of the pond the previous night and pawed at the roof of one of the beavers’ temporary lodges.

Willow was nowhere to be found but the next morning she came back to look closer at the bear  tracks. I know, I’m crying too. And remembering this.
[wonderplugin_video iframe=”https://www.youtube.com/embed/NqGMIDYl3-A” lightbox=0 lightboxsize=1 lightboxwidth=960 lightboxheight=540 autoopen=0 autoopendelay=0 autoclose=0 lightboxtitle=”” lightboxgroup=”” lightboxshownavigation=0 showimage=”” lightboxoptions=”” videowidth=600 videoheight=400 keepaspectratio=1 autoplay=0 loop=0 videocss=”position:relative;display:block;background-color:#000;overflow:hidden;max-width:100%;margin:0 auto;” playbutton=”https://www.martinezbeavers.org/wordpress/wp-content/plugins/wonderplugin-video-embed/engine/playvideo-64-64-0.png”]

The next morning I set myself the grim task of determining her fate. If I could not find evidence of a predator attack, I would assume that Willow had achieved the near-impossible—dying of old-age in nature. Frost crystals gleamed on the sedges by the pond, and a light skim of ice crystallized into snowflake patterns over the open water. I followed the beavers’ trails up the hillside again. I saw no evidence of predation. I returned to the place where the bear tracks left the scene. The tracks continued up the hill, went over a stone wall and up stone steps to a cellar hole. Bear feet left impressions along the edge of the foundation. At a corner, it looked like the bear paused to goof around with a branch since the tracks went back and forth, and a groove appeared beside them. As the tracks continued into the woods, the groove went with them. The bear was dragging something. I knew what I would find.

The pile of sawdust under a skim of ice looked like bedding from a squirrel’s nest at first. When it registered as Willow’s last meal, I dropped to my knees and howled my sorrow to the still forest. The depth of grief is a measure of love, so I welcome it. I loved that old beaver.

A week later, I made my sad return trek to the pond. The section of ice near the entrance to the lodge was slushy, and I made an opening with my ski pole. I called Henry and waited for many anxious minutes before I heard the gurgles that announced his approach. He rose to the surface wearing a cap of ice and then lumbered up the sloughing snowbank to beach himself, in magnificent portliness, for a treat. In his company by the moonlit pond, I found my farewells had already been said. The night demanded attention to what was there, not what was missing. I could feel Willow’s presence in Gentian, snoozing in the lodge nearby. Could she share her mother’s remarkable traits? If she does, she will live a long life — and she will share it with us.

I will never forget the wrenching feeling in Lily pond reading as Hope watches her beloved beaver die, I don’t know why, but women mourn beaver matriarchs and that’s just how it happens. There is of course always the fear of what will happen to the children. But I’m sure you know they were cared for. That night we all commented on how the yearling was accepting the kit for a back ride. We rarely saw those two apart in the coming month.

Patti, we are so grateful you allowed this beaver to touch your life. Your readers hearts and minds were forever opened because of it.

And thank you, Mom, and Willow.

Lastly; the Hubermans

Hans.

Papa

He was tall in the bed and I could see the silver through his eyelids. His soul sat up. It met me. Those kinds of souls always do – the best ones. The ones who rise up and say, “I know who you are and I am ready. Not that I want to go, of course, but I will come.” Those souls are always light because more of them have been put out. More of them have already found their way to other places. This one was set out by the breath of an accordion, the odd taste of champagne in summer, and the art of promise-keeping. He lay in my arms and rested.
