A Natural and Cultural History Guide to the Blue House

August 3rd, 2017 | Posted by in Graduate M.Ed. Program

By Angela Burlile, graduate student in the Institute’s 16th cohort. 

During our Place-Based Learning in the North Cascades course this past summer, I discovered the power of place and the role that place has on our sense of self and the development of our ecological identity. A sense of place can be developed when one purposefully considers their relationship to the landscape and builds meaningful and personal connections.

Throughout much of the summer, we examined a pedagogy of place, reinforced through experiential practice and supportive reading material. In David Gruenewald’s, “Foundations of Place: A Multidisciplinary Framework for Place-Conscious Education”, he states:

“A multidisciplinary analysis of place reveals the many ways that places are profoundly pedagogical. That is, as centers of experience, places teach us about how the world works and how our lives fit into the spaces we occupy. Further, places make us: as occupants of particular places with particular attributes, our identity and our possibilities are shaped.”

I carried Gruenewald’s words and the idea of purposeful examination and connection to land with me as I moved into my new graduate residence at the Blue House in August 2016. Purchased in 2015 by the North Cascades Institute, the Blue House provides residential housing space for graduate students and staff. It was built in 1912 and currently sits on 7.7 acres of land, along the confluence of Diobsud Creek and the Skagit River.

Who Cares About Beavers? We Do!

Everyone, meet Chompers!  In October 2016, during the fall natural history trip, my cohort helped the Methow Beaver Project volunteers to release the last 3 beavers of the season.  So much fun! We carried the beavers for several miles and released them at Beaver Creek. When we opened the cage, Chompers went right into the water.  It was fascinating to watch the three beavers explore their new environment.  This summer, the Methow Beaver Project workers will locate Chompers and the other two beavers to record their journey since the fall. This experience made me more curious about beavers and their role in the ecosystem. As I did more research, I realized how awesome beavers are!

Beavers are so wonderful that they are known as environmental engineers.  Beavers are known as a “keystone” species because of their large effects on landscapes.  It only takes a few beavers to transform a watershed entirely.  Beavers, with the exception of human beings, do more to shape their landscape than any other Chinese Teapots Wholesale Chinese Teapots Amber Spiral Bracelets! Beavers are also a “foundation” species because their presence and their creations, such as dams, allow other plants and animals to exist.  

Beavers’ creations are essential to its environment for many reasons.  First, beaver dams are natural filters, as they capture and store much of the sediment.  Streams that have been shaped by beavers have 10 times greater purification capability than streams without beavers.  Also, beaver dams store water, thus leading to the increased size of wetlands. Beaver dams can help mitigate the effects of drought and the loss of wetland and riparian habitats due to their abilities to store shallow groundwater and retention of surface water behind dams.   This is important because almost half of endangered and threatened species in North America rely upon wetlands.  Also, freshwater wetlands have been rated as the world’s most valuable land-based ecosystem.  Beaver ponds increase both the water we can see on the surface and also what is stored beneath the pond.  This helps increase the riparian area and vegetative productivity.  Not only do beaver dams store water, they also help slow down the water flow, which is why they are known as ‘nature’s speed bumps.’  They reduce stream velocity and power, which helps reduce erosion rates and the amount of sediment carried downstream.  This effect across the upper watershed could provide more time for flood planning, protection and evacuation of high risk, residential areas.  Beaver ponds also help stabilize the water temperature both in the shallow and deeper areas – they help cool down streams, creating better conditions for fish, especially trout.  Last, but not last, beavers’ modification on watersheds help increase organic material, such as cut wood and flooded plants, sediment with nutrients attached and more water surface area for photosynthesis to occur, which results in more aquatic biodiversity and food for fish.  Without beavers and the role they play in watersheds, most of the biodiversity that are associated with wetland habitats would disappear.
