Western Skunk Cabbage
The Western Skunk cabbage is also known as the Swamp Lantern its scientific name is the Lysichiton americanus.
The Western Skunk Cabbage is located in the Pacific Northwest from southern Alaska to central California it has been found as eastward as Montana.
The Western Skunk Cabbage is found in marshy swampy wet areas, and needs partial light and partial shade.
The skunk cabbage is in the Arum family. It can grow up to five feet tall and two feet wide. The flowers are yellow-green and have an outer spathe. The skunk cabbage gets its name from its unpleasant odor. The skunk cabbage uses this odor to get pollinated by flies and beetles. The skunk cabbage is very unique in that it can generate its own heat up to 35 degrees Celsius above the outside temperature. They also have contractile roots that pull the plant deeper and deeper into the mud or marsh. They develop massive root systems that go very deep. Because of these contractile roots many sources including Steve Schimmrich a professor in New York state, claim that the skunk cabbage could live for hundreds of years as long as the area around it stays wet. Generally speaking the skunk cabbage is the first to bloom in the spring some time from early march to mid April. The flower is not usually eaten by humans, it contains poisenous oxalate crystals that are pretty disruptive to the digestive tract. Many Native tribes used the flower and leaf to store salmon. The roots however are eaten regularly by a variety deer and bear. Historically the skunk cabbage been used to treat burns, arthritus, athsma and even to induce abortions. Today skunk cabbage extract is used to treat bronchitis.

I really enjoyed this first trip. It was a nice way to smoothly introduce us to the way that the trips will run, and it was a very comfortable place that we have all seen many many times. I had some trouble identifying the foul, but that was mostly because they were too far away to see properly. All in all I would say this was a very nice trip.

It was a nice trip on a sunny day and being in a class thats focus is like this made me focus on the animals, bugs and plants that I would normally just walk by. Getting to walk out onto the duck flats was also something that I have kind of always wanted to do too, it was interesting to look at all the things we saw besides all the trash. It was fun and I am exited to go on our other trips to see what we might find.

I have wanted for some time now to explore the flats and now I am very glad to have had the opportunity. I was able to see many plants and animals because of this field trip and I am confident to know that I can positively identify the organism well. I cannot wait to explore more of the Alaskan environments and become very knowledgeable about the wildlife.

After the Duck Flats trip
The tide was up on my way home last night-all those ducks we were trying to see were right by the road! There were 6 Dusky Canadian Geese in the flats right by Loop road. The Dusky is a subspecies of the Canada goose with a pretty restricted range and breed almost entirely in the Chugach.
Here's an interesting link about the Dusky Canada Goose
