Live action--what fun. And video to boot.

the dam and its creator. 13 April 2014.

Last night my splendid wife and I decided to take a quick walk through the park, and to look at the camera. I was especially anxious to see how much damage was done to the pond by the recent rains.
As we approached the beaver pond, we both noticed water rippling.

Boy howdy, did we time it right.

The beaver was out and active. (Can you see it it the picture above placing a stick on the dam?) Too cool.

We spent several minutes watching. My wife actually saw 2 beavers. She saw the second only briefly, near the dam. The one that stayed in view placed two sticks on the dam, and some mud and leaves. We also saw it leave the pond and spend a couple minutes near the large tree that it still hasn't finished eating through. It appeared to be eating grass.
















So, I leave you with 2 videos of the beaver in it's pond.

A dozen good things beaver ponds do for the environment

the dam. 9 April 2013.

I checked the beaver today, and discovered that the tree is still standing.

 I decided to keep the camera looking at the tree, as I think it might be fun to capture its fall on camera.
(Wish me luck with that, please.)

As you can see, the beaver is still working on the tree.




While poking around the area, I noticed some other interesting things. From an earlier entry, you may recall that the beaver cut down a tree, but that the tree got hung up in vines and didn't fall to the ground. Today, I noticed that our rodent friend has cut through the vine, allowing the tree to drop to the ground.

The vine the beaver cut to free the tree.

How's that for problem solving?

I also noticed an art installation in Minebank Run. It is unsigned.

Courtesy of North Carolina State University, I leave you with a list of Beaver Pond Benefits

Active Ponds

1. Improve downstream water quality
2. Provide watering holes for agricultural and wildlife needs
3. Supply important breeding areas for amphibians and fish
4. Provide diverse wetland habitats
5. Furnish feeding, brood rearing and resting areas for waterfowl
6. Encourage many reptile, bat amphibian, fish and bird species

Abandoned Ponds

1. Furnish snags for cavity-nesters and insectivores
2. Fallen logs supply cover for reptiles and amphibians
3. Provide essential edges and forest openings
4. Supply diverse moist-soil habitats within bottomland forests
5. Create productive bottomland forests
6. Provide foraging and nesting areas for bats, songbirds, owls, and hawks

92 species of birds can't all be wrong

30 March 2013.

I checked on the camera today, and am delighted to see that the beaver is still active.

 It is still chomping on the big tree that it has been chomping on for a couple weeks.  This is , by far, the biggest tree in Cromwell Valley Park that it has  cut down or tried to cut down.  I don't know if that is significant or not. One source I checked says that beavers only cut down large tree when smaller ones are unavailable.  That does not seem to be the case here. 

the old dam. 30 March 2013.

I also took a walk down to the first dam and den that the beaver built. You may recall that a flood at the

end of January, forced the beaver to look elsewhere for a home. The remnants of the dam are still visible, but with a large hole eroded in the center. Similarly, the den is still visible, but the hole made by an animal has eroded, and is filled with sticks.

So, we all know that beavers destroy a lot of trees. But they do more than destroy. They create as well.

squirrels, deer, rabbits, fox, and a beaver. Oh My!

It's spring break so I had the pleasure of my son's company this week. We had a great week, and a very successful one. So let's not waste a lot of time with words. Let's just enjoy the results.

Eureka! Let's enjoy this as long as it lasts.

I checked the camera yesterday afternoon, and again this afternoon. I am glad to report that I've finally caught or favorite rodent on the camera. What fun.

I also observed an interesting phenomenon. 

I saw a tree nearly cut down by the beaver.

When I looked closer, though, I realized that the tree was ready to fall. Sadly for our rodent friend, it was hung up in branches of other trees, so couldn't fall. All that work and no food. Drats.

One last note. While out today I met a man who is attempting to trap the beaver, apparently at the request of the Park Manager. He said that he is going to relocate the beaver if he succeeds in catching it.

My shortest post ever

So....I went to check on a technical difficulty with the camera this afternoon after work.

the water level is rising. 2013-02-25

I had to cross Minebank run upstream from the beaver dam and pond. The beaver has been busy. I just about 27 hours, the water in the pond has risen about 2 inches. In the photograph to the right, you can see some stones under water. When I used them yesterday to cross the stream, they were about half above the water. Now they are just submerged under the water.

It's a busy little beaver, isn't it?

2013-02-25.

Here is the camera in place. It is overlooking the slide on the west bank of the stream. Maybe one of these days I will actually catch the beaver on the camera. Wish me luck.

What's new this week

new dam. 2013-02-24.

The beaver is still active in its new location. That's the good news. The continuing news is that I still have failed to capture the beaver with the trail camera. The bad news--nah. It's too nice a day out, and my trail companions of the afternoon were far to nice people to have bad news.

We had a nice afternoon nosing around and made some observations. We did not observe a beaver lodge or den. Perhaps, the beaver is living somewhere in this mess of sticks piled up on a fallen tree? You can see the pile on the left of this picture. There is another on the opposite bank, not visible in this picture. You can't see it, but the dam is behind the fallen tree. This photograph is looking downstream. You might also observe the evidence of heavy flooding along the stream and it's banks. Notice that some of the banks are undercut by the heavy currents? Trees are falling in to the stream.

Stormwater is the only source of pollution to in the Chesapeake Bay that is increasing.

the new entrance to the old den.

The old dam is almost gone. Still lodged behind what is left of it is a lot of silt. The old beaver lodge is still visible, and so is the hole that some other animal has dug, presumably to reuse it as a new home. Perhaps when the weather, and the water, warms, I will get in the stream and try to find the beaver's entrance tunnel. It is not visible from either bank.

leftovers from someone's dinner.

We also saw some deer bone that some animal has dragged on to the path. I don't know if this is from a wild animal or a dog. A great number of dogs are led along this path. I wonder what the beaver thinks of so many dogs running over its home? They haven't caused it to leave yet.

Finally, even though I have failed to record a beaver with the trail camera, we do have red fox in the area.
