Sunday Hunt For Links – North American Beaver Edition

Shortly after I started my Sunday Hunt For Links series, I wrote a post that featured the Bison or Buffalo. I chose it because of it’s rich tradition and history with Native Americans. The animal I Beaverchose to feature today has it’s own history with Native Americans and also with the explorers and settlers who came from the east to the west, seeking to learn more about what would some day become the United States of America. The fur trade in North America was one of the main economic forces on the continent, as early as 16th century. It was then that the Europeans discovered cod fish could be dried, which preserved it for shipment back to Europe for sale. That was done off the Newfoundland coast and during that time, these fisherman also traded for robes made of sewn-together beaver pelts to help keep them warm as they traveled across the Atlantic. Once those robes reached Europe, it didn’t take long for them to be converted to felt, specifically for the making of felt hats. It was from this simple act of the necessity to keep warm that the North American Beaver became one of the most sought after animals in the world. It was truly the driving force behind the fur trade in North America and it nearly drove the third largest rodent in the world to the point of extinction.

The beaver is another of God’s amazing creations. From it’s instinct to dam streams and create wetlands, all manner of other wildlife are affected positively. It probably has more power to do that than any other animal in the world. Let’s take a look at some of the physical details of the beaver, courtesy of Wikipedia.

The beaver is the largest rodent in North America and the third largest rodent in the world, after the South American capybara and the Eurasian beaver. Adults usually weigh 15 to 35 kg (33 to 77 lb), with 20 kg (44 lb) a typical mass, and measure around 1 m (3.3 ft) in total body length. Very old individuals can weigh as much as 45 kg (99 lb).

Like the capybara, the beaver is semi-aquatic. The beaver has many traits suited to this lifestyle. It has a large flat paddle-shaped tail and large, webbed hind feet reminiscent of a human diver’s swimfins. The unwebbed front paws are smaller, with claws. The eyes are covered by a nictitating membrane which allows the beaver to see underwater. The nostrils and ears are sealed while submerged. A thick layer of fat under its skin insulates the beaver from its cold water environment.

The beaver’s fur consists of long, coarse outer hairs and short, fine inner hairs (see Double coat). The fur has a range of colours but usually is dark brown. Scent glands near the genitals secrete an oily substance known as castoreum, which the beaver uses to waterproof its fur.

It should also be noted that castoreum was also a highly valued trading item, sought for it’s medicinal properties. Again, I go back to mentioning the economic force of the beaver, but I do not believe it can be understated.

Outside of it’s fur and castoreum, the one thing the beaver is best known for is it’s ability to build a dam across a stream. Doing this creates wetlands for other species of wildlife. According to Beaver DamBeavers: Wetlands & Wildlife, the beaver’s ability to change the natural landscape is second only to that of humans. These dams and the subsequent wetlands are a marvelous work of ingenuity and I can tell you from first hand experience, they are a wonder to behold. My Dad has a pond that has a beaver population living in it and they decided the culvert he installed as a spillway was letting out too much water. They have it so dammed up that it would take a bulldozer or backhoe to extract it and would probably result in the destruction of the south end of the earthen dam that was put into place when the pond was dug years ago. The beaver really know how to build a dam. Consider this, from the link at the beginning of this paragraph.

Beavers are more than intriguing animals with flat tails and lustrous fur. American Indians called the beaver the “sacred center” of the land because this species creates such rich, watery habitat for other mammals, fish, turtles, frogs, birds and ducks. We now know that beaver damming provides essential natural services for people too.

Beavers prefer to dam streams in shallow valleys, where the flooded area becomes productive wetlands.These cradles of life support biodiversity that rivals tropical rain forests. Almost half of endangered and threatened species in North America rely upon wetlands. Freshwater wetlands have been rated as the world’s most valuable land-based ecosystem.

Beavers reliably and economically maintain wetlands that sponge up floodwaters, alleviate droughts and floods (because their dams keep water on the land longer), lesson erosion, raise the water table and act as the “earth’s kidneys” to purify water. The latter occurs because several feet of silt collect upstream of older beaver dams, and toxics, such as pesticides, are broken down by microbes in the wetlands that beavers create. Thus, water downstream of dams is cleaner and requires less treatment for human use.

Many people may think the beaver just eats wood, but that isn’t the case. They do prefer the bark of the willow, maple, birch, aspen, cottonwood, beech, poplar, and alder trees, but one of the mainstays of their diet is the cambium, which is the soft tissue just underneath the bark of a tree. A beaver will also eat roots and water lily tubers. To ensure they have plenty to eat during the winter, they store freshly cut branches in and around their lodge.

Speaking of the house the beaver built, no discussion about beavers would be complete with mentioning their lodges. To do that, I again refer you to Wikipedia.

Beaver LodgeThe ponds created by well-maintained dams help isolate the beavers’ homes, their lodges, which are created from severed branches and mud. The beavers cover their lodges late every autumn with fresh mud, which freezes when the frost sets in. The mud becomes almost as hard as stone, and neither wolves nor wolverines can penetrate it.

The lodge has underwater entrances to make entry nearly impossible for any other animal (however, muskrats have been seen living inside beaver lodges with the beavers who made them). A very small amount of the lodge is actually used as a living area. Contrary to popular belief, beavers actually dig out their dens with underwater entrances after they finish building the dams and lodge structures. There are typically two dens within the lodge, one for drying off after exiting the water, and another, drier one where the family actually lives.

Beaver houses are formed of the same materials as the dams, with little order or regularity of structure, and seldom contain more than four adult and six or eight young beavers. Some of the larger houses have one or more partitions, but these are only posts of the main building left by the builders to support the roof, for the apartments usually have no communication with each other except by water.

When the ice breaks up in spring beavers always leave their embankments and rove about until just before fall, when they return to their old habitations and lay in their winter stock of wood. They seldom begin to repair the houses until the frost sets in, and never finish the outer coating until the cold becomes severe. When they erect a new habitation they fell the wood early in summer, but seldom begin building until nearly the end of August.

There are many other items of interest about the beaver. For instance, did you know that they will not overpopulate the area in which they live? They only breed once a year and when the occupancy reaches a certain level and food is scarce, the number of beaver kits is reduced. I could go on and on, but I think you get the idea that the beaver is one fine example of nature at it’s finest. Now to the hunt for links.

    I once did a series of articles on each of the 50 states. Its always refreshing to step back from politics, take a break and remind ones self of the greatness of America. That seems to be missing rather dynamically from todays debates. I got the idea by traveling a lot of late and when driving through various states I would listen to local radio stations describing something of local interest.

    That would tweak my interest and when I got to a motel I would whip out my laptop and look it up so that I better understood what they were referring to.

    What made me sad was that when my daughter was 16 years old she asked me one day if she could go out on a date….jokingly I said “only if you can point to and name 10 states on the map”

    At the time we were looking at the weather channel and they had up a map of the USA. She could name 2 states and could not even identify the state she was currently living in.

    She called her bigger sister into the room and together they were able to identify 7 states….7 states between a 16 and 18 year old.

    So today I send them postcards from everywhere I visit with my job….they have become real geography nuts in their older ages with their own children going to school now.

      Thanks for the comment, Doomed. I suspect your series on the states was quite interesting. Did your daughters get the states figured out?

  • http://motorcitytimes.com/mct/ steve

    Great post Larry. I look forward to your Sunday morning ‘critter posts’ they are very fun and interesting.

    • http://www.ldjackson.net LD Jackson

      Thanks, Steve. They take me quite a while to put together, with finding the right images and writing the feature about the animal. I quite enjoy doing them, as I usually learn something I didn’t know myself.

  • http://www.Bunkerville.wordpress.com Bunkerville

    Thanks again for the link and great story. I will spin back around to spend some time.

    • http://www.ldjackson.net LD Jackson

      You are quite welcome, Bunkerville.

    I have now made it a habit to start my day by grabbing my cup of tea, pulling out my laptop and coming here. I love this series you do. This is Larry at his best, I think. I hear the history buff come out in these posts as well as your deep admiration for the natural beauty that God has endowed our country with.

    The beaver truly is an amazing animal. I am always amazed how these animals instinctly understand what they are called to do. It is amazing. I often wonder about the great truths they could teach us if we would just take the time to get to understand them and learn from them.

    Awesome job. Thank you for great start to my day. And for the link of course. :-)

    • http://www.ldjackson.net LD Jackson

      You are welcome for the link and thank you so much for the nice compliment. It is true that I love doing these posts, probably more so than any that I do.

  • http://conservativesonfire.wordpress.com Jim Gourdie

    I wish more people were as industrious as the beaver. Thanks for the education and thanks for the link.

    • http://www.ldjackson.net LD Jackson

      You are quite welcome, Jim.

  • http://conservativehideout.com/wordpress Matt

    Thanks for the links, Larry. I like how Steve refers to these as “critter” posts.

    • http://www.ldjackson.net LD Jackson

      You’re welcome, Matt. I really enjoy writing about these “critters”.

    Great info here Larry. Did you know that Canada’s national animal is the beaver? Thanks for the link my friend. It is much appreciated.

    • http://www.4wallsandaview.com Dominique

      I just learned something else! :-)

    • http://www.ldjackson.net LD Jackson

      You are welcome, John. Yes, I knew the beaver was Canada’s national animal. I almost mentioned that in the post.

  • http://rjjrdq.com rjjrdq

    Thanks for the link, LD. 99 pounds?! I had no idea.

    • http://www.ldjackson.net LD Jackson

      You are welcome, rjjrdq.

  • http://www.spellchek.wordpress.com 5etester

    Thanks Larry. Interesting how perspective changes opinion. Everyone seems to like the beaver (unless you have a water issue ), yet no such love for the other members of the rodent family.

    • http://www.ldjackson.net LD Jackson

      You’re welcome, 5etester. I think the reason don’t have such love for other rodents is that they see no purpose for them. That’s why so many people dislike the prairie dog, but my post on it proved it had much more purpose than most people ever imagined. Maybe I should write about the rat?

  • http://capitolcommentary.com Harrison

    “Nice beaver!”
    “Thanks, I just had it stuffed.”

    Thanks for the link!

  • http://americaswatchtower.com Steve Dennis

    It is amazing the way that all of nature is intertwined, even what we consider the most inconsequencial of creatures serves a purpose in the overall scheme of things. The beaver creates wetlands and this allows other animals to thrive, everything in nature is connected.
    Thanks for the link Larry!

  • http://maggiesnotebook.com Maggie Thornton

    Larry, I think you enjoy writing these as much as everyone here enjoys reading them. The pic of the lodge is fascinating. I had no idea that beavers use the same lodge over and over every year.

    In one of James Michener’s books, Centennial I think, in the long historical introduction he does, there was a female beaver. She wasn’t very pretty, and she had a really tough time finding a male beaver to spend her life with. It was so poignantly written that I have never forgotten it. Eventually she finds the love of her life, and at the end of that life, she climbs up on an underwater shelf that I think had something to do with the Rockies and dies there. Centuries later, someone finds her beautiful fossilized body on that shelf. Can’t remember if her man was with her or not.

    Thank you so much for the link. I love finding new blogs to me here.

    • http://www.ldjackson.net LD Jackson

      You’re welcome, Maggie. Yes, I do enjoy writing these posts. I think that’s why they tend to be longer than my normal posts. It’s hard to find a stopping point.

      That’s an interesting story about the beaver in James Michener’s book. Thanks for sharing.
