New festival promo from Sarah!

Martinez Beaver Festival Promo 2016 from Tensegrity Productions on Vimeo.



One evening at the Tulocay Creek Beaver pond in Napa a Beaver seemed entranced with eating the grass and ignored me, and almost appeared to want to do a modeling photo shoot.

On my way to leave a Muskrat decided to grab a bunch of leaves from the top of the main Beaver Dam. Usually the Muskrats eat grass.

New festival promo from Sarah! Hopefully Rusty will embed it for you because I am too stupid to manage it on the iPad. Last night was a crowded hoot. Lots of laughs in the right places and maybe 100? Beaver believers in the house. We had a blast and have many stories to share, but we are off to Clean water services in Beaverton this am an I must dash for now!



Beavers go Big

Hey it’s a long drive to Portland from Martinez, who knew? It rained a little all the way up but don’t worry, it took 610 miles but we finally found the traffic! All of a sudden we were surrounded by millions of very hydrated and creative automobiles interrupted by sites like this.

We had a noisy night in Grants Pass and we’re thrilled to stumble into our snug guest house  in SE Portland, where raspberry canes and fresh snow peas were growing right outside our door!


Today it’s sightseeing, coffee and maybe a little pok pok before we head to the Ballroom tonight for the big event. I can see I’ve left you in enormously capable hands as Rusty did a fantastic and polished job yesterday. Keep an eye on those Napa beavers! And I heard news that Mario painted a third beaver on the bridge but no one’s sent me a photo so I’m feeling very deprived. Hopefully a remedy is forthcoming!

Wish me luck tonight. It’s gotta be easier than the drive, right?

Due to disastrous floods in Napa there has been a lot of flood control work done in the last few years. One of the problem areas is where Napa Creek flows through downtown Napa. Napa Flood Control has done bank restoration in the area after extensive flood control work.  Some existing larger trees have been protected with wire mesh, and some trees have been planted that are left unprotected for Beavers to eat. (note; Napa Flood has been using a heavy duty fine wire mesh with good results although the standard protection is larger 2″ x 4″ mesh)wrapped trees downtownBelow is a Beaver dam that appeared in Downtown Napa across the street from Kohl’s Department store about two years ago.downtown beaver dam

This year Mink were seen for the first time, along with turtles. So far no Muskrats.

Out the door…

Late to the party is better than never coming at all. Here’s yet another report on the benefits of beavers to nitrogen removal.


Knocking Down Nitrogen

Beavers have long been admired for their dam-building skills, which enable them to create ponds and slow the movement of water. Recently, a team of University of Rhode Island scientists has discovered that their environmental engineering tactics also help mitigate levels of nitrogen in the water.

According to Arthur Gold, URI professor of natural resources science, nitrogen levels have been increasing in northeastern streams for many years, due largely to the increased use of fertilizers. When nitrates travel from watersheds into estuaries, they trigger algal blooms that lead to dead zones, fish kills, and the degradation of marine habitats. Gold has spent his career studying the movement of nitrogen across the landscape to better understand how various habitats either remove or retain nitrogen.

“We found in our earlier studies of nitrogen movement that when a beaver pond was upstream it would confound our results,” Gold said. So he and doctoral student Julia Lazar decided to investigate beaver ponds to see what happens to nitrogen there.

They found that beaver ponds create ideal conditions for nitrogen removal, or denitrification. The organic matter that builds up behind a beaver dam plays a key role. That’s where bacteria transform nitrates into nitrogen gas, which dissipates into the air. Some nitrogen is also absorbed by aquatic plants and becomes stored in the sediments when the plants die. None of this would happen without the beaver dam because for substantial denitrification to occur, the water must remain somewhat still and in place for days or weeks at a time. In fast-moving streams, there is not time for the necessary biological and chemical processes that remove nitrogen.

‘The great surprise to us was that beaver ponds are very effective at nitrogen removal,” Gold said. Depending on the pond and the amount of nitrogen present, as much as 45 percent of the nitrogen in a beaver pond is removed from the water. “And most of it goes out as a gas, which is advantageous since beaver ponds are temporary,” he added. “At some point when the dam breaks, the nitrogen stored in the sediments behind the dam moves back into the water, so it’s better when we see it go off as a gas. Then it’s gone for good.”

Nice to see this covered but it’s too bad your readers didn’t visit, because they would have already learned about this in October.

Portland or Bust!

The day has finally come, I’ve practiced and adjusted my presentation for the last time,  Jean has officially stepped in to oversee the ongoing muralling, and now all that’s left is the doing and the driving. Stay tuned for some awesome photos from Rusty of Napa, and thanks to Robin for scanning this fun cartoon. There’s nothing to do now but wish me luck!

Positive and Negative beaver space

   Posted by heidi08 On May - 21 - 2016Comments Off on Positive and Negative beaver space

negNegative space refers to the space around the image being drawn or represented. Discussing its use happens to be a very fun thing to do when you’re a teenager on a field trip imitating a pretentious critic at a museum. It’s used to define or highlight the object or to make a space for the image that is going to be filled in later either by the artist or the viewer.

So we were delighted to see this yesterday morning:

negI’m sure you’re a normal person and lead a regular beaver-unobsessed life, but  maybe you already recognized that missing beaver is the famous beaver Mario was forced to paint over all those years ago. Ah memories!

Well, to paraphrase the words of what’s arguably the most imitated scary movie trailer ever made “He’s back!”

Come to think of it, I really need to see it all in on place to appreciate the progression:


It was meet that we should make merry,

and be glad: for this thy brother was dead,

and is alive again; and was lost, and is found.
