Northampton will install rocks to baffle beavers at Fitzgerald Lake

Hark back to 2013, when beavers dammed the area around the outlet pipe that sends water from the lake under the dam and into the Broad Brook. The lake rose about two feet that year, forcing the city to install a wire-mesh fence around the pipe, temporarily holding the beavers at bay.

 Ever industrious, the beavers eventually burrowed under the fence, clogging the system again and raising the level of the lake. Some of the trails along the shore were even submerged this year.

 Wow, Northampton MA is 20 minutes away from Mike Callahan. I can’t believe he installed a fence beavers burrowed under in 2 years, can you? Let’s use the search function on the website to see if it gives any clues. Here’s one from 2013:

“Once the new fence is in by the city’s contractor I’ll be installing a Flexible Pond Leveler through their fence.”

Ahhhh so it was a “I’ll-save-some-$$-by-doing-this-myself, how-hard-can-it-be” job.  Gosh and now you have to spend a grand lowering rocks into the lake to hold down the silly fence that you installed, because otherwise Mike’s excellent flow device will get plugged. Have you learned anything by this? Are you going to stick to the experts next time?

Mike said at the time that this lake was the site of the FIRST flex pipe he ever installed – in 1998. How’s that for a history lesson!

bob n janeOur dinner guests last night were Bob & Jane Kobres from Georgia. Here they are at the table with our awesome chef and FRO’s beautiful beaver watercolor in the background. He’s the retired librarian from UGA that always sends us beaver research and discretely points out egregious typos so that your reading experience will be slightly less marred. He and his wife made their first trip to California (first time ever) for the beaver festival. (No, really)

Every business they visited in Martinez they made a point of telling was stunned. And they just did a beaver presentation at the children’s program in their church. How awesome is that? At dinner we realized they are truly unique folks: Jane is the daughter of a white baptist deacon from Tennessee that voted for Obama twice.

(How small is that demographic?)

They had a great time watching Bob Rust put together the wattle beaver, and Bob filmed most of it so I hope we can get it on the website soon. They shared a similar knowledgeable quirkiness that I am starting to recognize in beaver lovers. (Myself included). It’s amazing that we have had three separate visits from Georgia in the past few years, and the Blue Heron Preserve in Atlanta is now talking about possibly doing a beaver festival. (Be still my heart!) They went to Muir Beach on their visit and boldly put their bare feet in the Pacific, as well strolling around Muir Woods and the John Muir house here in Martinez.

We’re just about finished with the final exchanges for the silent auction, meeting a lot of folk wednesday at the bridge, and everything is finally put away or tallied. I sent the followup receipts and paperwork for the grants yesterday, and am finally starting to feel done with everything. I got this fun photo from our bag piper yesterday, Dave Kwinter, who said he had a great time at the festival.

bvOf course I warned him to use caution when saying he enjoyed it, or else we will certainly ask him again!

 

 


Suzi at work
Suzi Eszterhas photographs Martinez Beavers

Last night more than 40 children and their parents showed up for a chance at having their picture taken by Suzi Eszterhas for possible inclusion in Ranger Rick magazine. I was in charge of registration at the footbridge and got parents to sign the model release. Jon shepherded groups across the street, and Suzi was at the old dam arranging children, persuading them to be patient, and taking photos.

The night had a strangely important feel. Almost everyone had seen the beavers before, and many knew about the kits, most had attended a beaver festival. One eager attendee showed me her three layered keystone charm necklaces from the previous years, and one boy was even wearing a lovely homemade t-shirt that said “Save the Martinez Beavers”!

(Jon got so excited about him that he told Suzi to get a photo, and when she was trying to walk around the edge of the pond she slipped in!  About three feet deep because of the swelling tide, but she instinctively held her camera over her head so everything important except her squishy boots was saved! Afterwards Jon was very sorry apologetic.)

nature clubThe kids and parents were very excited about her work and wanted to know as much as possible. Of course they asked which issue of Ranger Rick it will be in, and of course we have no idea. Hopefully sometime next year.  She was especially interested in the older kids because of the readership age of Ranger Rick, but  she made everyone feel important and part of something very special. Parents were totally unphased by the release which they happily signed and gave contact information. Afterwards Jon and I looked at each other and commented that this had felt like an unexpectedly important night.

I’m hoping this translates into lots of new sign ups for NWF at the festival and some great bidding on Suzi’s donations. Now today it’s time to buckle down with Deidre and get the items for the silent auction tagged and organized. Next week is full of last minute details and the Contra Costa Times is supposed to release its article about the festival (and profile of ….cough…me.) I’m just hoping it doesn’t mortify me too much.

What a great day yesterday! It started out by picking up a fantastic gift bag donation from Trader Joe’s (Thanks TJ), organizing the amazing donations from Folkmanis puppets (Thanks Elaine), getting two copies of the unbelievably exciting book DAM BUILDERS from the publisher(Thanks Natasha), sending the finished festival brochure to the printers, (thanks Amelia!) and finishing a spread sheet for a stunning 134 auction items! Here’s a little taste.

Then retired librarian friend BK from Georgia sent this my way, and it made everything even brighter. This is such a beautiful review from PHYS.org I’m going to print it all. And if they want to come get me I’ll take the consequences.Capture

Wildlife in built-up areas an undervalued part of our urban ecosystems

Urban wildlife such as deer, foxes and badgers should be cherished for the ecological benefits they bring to towns and cities, rather than feared as potentially harmful pests, scientists argue in a new report.

The review, published in the scientific journal Wildlife Research, states that in order for humans and animals to live successfully side-by-side in built-up areas, a cultural shift is required for the public to fully appreciate the integral role that wildlife performs in urban ecosystems.

 Much of the public dialogue about larger urban wildlife currently focuses on the risk of disease, pollution and threat to property or pets, rather than the positive contribution these animals can make.

Lead author Dr Carl Soulsbury, a conservation biologist based in the School of Life Sciences at the University of Lincoln, UK, said: “While promoting education about urban wildlife and its risks is important, the benefit wildlife brings to urban areas is often poorly communicated. It includes benefits such as regulating and supporting the ecosystem, through to improving human health and wellbeing.

“We need to identify ways to maximize the benefits, in particular increasing the accessibility of natural green spaces and promoting interactions with wildlife as a form of nature-based therapy. It is only through such an integrative approach that we can advance our understanding of how to live successfully alongside wildlife in an increasingly urbanised world.”

How beautiful is THAT for a beginning?  Wildlife in our cities is a treasure NOT a nuisance, and the problem is that people complain too loudly about the problems and don’t talk about the benefits. I have already written to Dr Soulsbury, because we obviously need to be friends.

 The researchers detail how urban wildlife can provide a range of benefits to human health and quality of life which are often undervalued or overlooked. For instance, there is a growing body of evidence that indicates the presence and viewing of urban wildlife is beneficial for human mental health and psychological wellbeing.

Urban animals also regulate and support the ecosystems of towns and cities. Many creatures serve as important predators of pest species – for example, songbirds help to control insect populations and predatory birds help rodent control.

 But as urban human populations continue to grow, so too does the chance of ‘human-wildlife’ conflict, the researchers warn.

These conflicts occur when the activities of wildlife, whether through aggression, nuisance behaviour such as bin emptying or the spread of parasites or infectious diseases, have a negative effect on humans. Most such problems are minor, but can be distressing to individuals and tend to shape attitudes of the public and authorities.

 Dr Soulsbury added: “The main problem is that many of the benefits of living alongside urban wildlife are difficult to quantify. However, we do know that the presence of wildlife gives people an opportunity to connect directly with nature at a local level. This is becoming particularly important in our increasingly urban society where humans are becoming more remote from the natural environment.

 “More work is needed to better understand the role of urban wildlife and urban biodiversity in general, in the promotion of mental health and its greater role as a recreational and cultural ecosystem service. To do so wildlife biologists will need to work with other research disciplines including economics, public health, sociology, ethics, psychology and planning.”

 I agree! Hmm can we think of any psychologists we might know interested in co-authoring a research paper on this topic? Maybe one with a yearly access to a sample size of 2000?

I’m in love with this article and think I need the paper to which it refers. None of my usual sources can access it yet, so it might not be available. Here’s the link for the abstract if you’re feeling scientific. All I can say is that maybe Dr. Soulsbury needs to come to Martinez for some field research. I’m thinking August would be the perfect time.

No new deaths, and Jr. was seen last night. How quickly the standard for good news changes when you are living in a war zone. The dam was worked on too, meaning the beavers themselves are feeling back to normal. I guess we should try and do the same.

These are nice articles to bring us gently back to the land of the living.

North woods entrepreneur: New beaver pond shows the power of the beaver’s creative destruction

To a beaver, the slightest trickle of water is the sound of opportunity. It’s said you can give a man a fish and he’ll eat for a day. But, I say, give a beaver the barest of brooks and he’ll create a new world.

It’s a process of creative destruction that kills a forest and replaces it with a rich wetland environment that, in its first summer, is already home to at least three broods of mallards and probably more.

It’s a perfect environment for raising young ducks. The pond, which is isolated from any open water source, obviously harbors no giant muskies waiting to inhale a downy little duckling. And the canopy of now-dead alder and aspen offers the young ducks substantial protection from hawks or falcons.

But there was much more at the new pond early one morning this week. Frogs were poking noses from the water, a garter snake was coiled on a sun-splashed rock on the shore, while legions of dragonflies darted around in search of breakfast or a sunny perch of their own.

In the long view, beaver ponds are temporary components on the landscape, even though they can last, at times, for decades. Over time, they change, of course. Our new pond is full of woody cover, but soon enough those dead trees and shrubs will disintegrate and fall below the surface of the dark waters, opening up the pond. The brush will be replaced with true wetland vegetation, like cattails, rushes, or sedges. If they haven’t already, turtles will eventually find their way to this oasis in the forest. I’m curious to watch the transition over the years to come— assuming that the beavers and their progeny continue to maintain the dam.

I love a beaver article that takes the long view on beaver impact. But  Marshall Helmberger stopped short of mentioning the egrets and herons that come to the pond to eat those frogs, and the fish that feast on the dragonfly larvae. Not to mention the mink and otter that come feast on the fish. How about the nutrients that will accumulate in that damp soil and the many plants that will eventually settle in that meadow? I’ll let Dr. Wohl explain:

I never get tired of hearing that clip. That is the best lightening overview on beaver impact I have ever heard. Even better than Enos Mills, and that’s saying something. Ellen donated another book for the auction, this one looks like an excellent summer read.

A combination of travel writing, nature writing, and science writing, Transient Landscapes is a beautiful and thoughtful journey through the natural world.

Now on to my favorite beaver article this season, I have tried to track down the author but had no luck yet. This appeared yesterday in the News Tribune in Washington state. (Of course)

Eager beavers seeking summer fun can rely on these tips from the animal world

Here are five ways your kids can be more like a beaver this summer.

Tip 1: Create your own shelter

Have you ever pitched a tent outdoors, or gathered all the pillows and blankets in your house for an epic pillow fort? It’s amazingly satisfying to put a roof over your own head, even if it’s just for fun. Beavers are known for creating their own homes, called lodges.

Tip 2: Hang out with your family

If you spent the summer by yourself, you’d probably get bored. A beaver would feel the same way. They love to play and socialize with their family members every day. Beavers live in family groups called colonies.

Tip 3: Eat a healthy snack

 Nothing tastes better than fresh veggies found at the local farmers market. North American beavers have diets based on the plants found in their natural range, which includes Canada, the United States and northern Mexico. They love to eat bark, twigs, aquatic plants, and the leaves and roots of deciduous trees.

Tip 4: Go for a swim

What’s the best way to cool off in summer (aside from eating Popsicles all day)? Taking a dip in the pool, of course. Swimming is a refreshing activity for lots of animals and a major part of the beaver lifestyle.

 Tip 5: Help habitats

All living things are connected, and every animal needs a home. Protecting and creating homes for other animals is a great habit to practice every summer (and the rest of the year, too). You can try it yourself by planting trees, building bird houses or bat shelters, or volunteering for habitat restoration projects.

Beavers modify their surroundings quite a bit. In the process of creating lodges, dams and canals, they create rich habitats for other animals. Cutting down trees allows shrubby plants to grow, which are great food for deer and elk in winter. Beaver ponds also attract frogs that are hunted by weasels, raccoons, herons and others. Ducks and geese may build nests on top of beavers’ lodges.

A beaver colony is a good thing for a healthy forest.

I love. Love. LOVE. This article! How it of course PRESUMES that children might want to be like beavers. How it finds ways to educate children about beaver adaptions by pairing them with things they already know. And of course how the last paragraphs emphasize that beavers are GREAT for other animals in the forest.

Love.

I don’t know about you but I can see the beginnings of a beaver badge tied in with the festival, in which children show us they have taken beaver action during the season and earn something to acknowledge their role in the colony! Maybe they even get the list of how to be like a beaver at earth day, check the items off and turn it into us at the festival?

Hmm we’d have to add one of course. Teaching others what you know. Beavers do that all the time.

Blue Heron on beaver lodge in Tulocay Creek: Rusty Cohn

CaptureBeavers set up home in downtown Napa

Downtown has some new residents, and they’re not the two-legged tourist variety.  Beavers have moved into Napa Creek and built at least two dams visible from the Pearl Street pedestrian bridge and from the parking lot behind the former Napa Firefighters Museum.

 “I think it’s great. It speaks to the health of the watershed,” said Shaun Horne, watershed and flood control resource specialist for the Napa County Flood Control and Water Conservation District.

 “It’s a good sign for the creek,” Horne said. “The whole beaver population seems to be spreading. These creatures are recolonizing some of these areas that maybe didn’t have the best habitat prior to this.”

Beavers change creek hydrology for the better, Horne said. Dams pool water, which is good for fish, birds and other wildlife. Beaver dams can also help reverse channel deepening, provide nurseries for fish, increase habitat for small mammals, contribute to the establishment of new vegetation and improve downstream water quality by trapping sediment.

 Napan Rusty Cohn is a regular beaver watcher. He’s seen the animals and their work at Tulocay Creek near Soscol Avenue and other river areas in the city. He gave the new dam on Napa Creek a thumbs-up.

 “They did a nice job of building it,” Cohn said. He has yet to spot the downtown beavers, but he has a theory about where they came from.

More remarkable beaver wisdom from Napatopia, with Flood control saying how valuable beavers are and Rusty getting some smart quotes in. I can’t figure out thought why they didn’t run some of his great photos, or the news that there are three new kits in Tulocay creek. Reporters remain a mystery to me, but you are encouraged to solve the puzzle for yourself.

More good news from places that aren’t here. Brace yourself. This is surprising. The state of Ohio (OHIO?) Department of Transportation has apparently contracted with Mike Callahan to teach them to install flow devices to control beaver damming rather than killing them Here is proof they’re listening.

A Possible Beaver First!

Last week in Cincinnati the Ohio Dept. of Transportation hired me to train their personnel how to manage beaver problems with flow devices. Is anyone aware of another state Highway Dept. that has committed to building and installing flow devices themselves? I think Ohio may be the first! Here in Massachusetts the MassDOT is very supportive of flow devices but they contract with me to install them. Ohio wants to start doing flow devices themselves which I think is pretty cool!

All this came about due to local beaver advocate Karen Arnett being persistent and lobbying the ODOT to consider flow devices as an alternative to trapping. Her dogged efforts bore fruit and the beavers, humans and ecosystems of Ohio are bound to benefit.

The ODOT training included a PowerPoint presentation tailored to ODOT needs, and a hands-on flow device installation where many ODOT staff participated. The flow device install site is a highway retention pond where unfortunately beavers were trapped last year. Since new beavers are bound to relocate here ODOT wanted a flow device to protect the drainage structure and prevent the need to trap in the future. I was very impressed with the level of interest by ODOT staff and their willingness not only to do the work but also get in the water. See pictures. Kudos to ODOT as well as to Karen for getting ODOT interested in flow devices!

Karen contacted this website ages ago, and Beavers: Wetlands and Wildlife as well. She really did a stellar job of getting new ideas through thick skulls. And Mike did a great job convincing them once she got their attention. Great work team beaver!
