Logging and Mudslides

Logging and Mudslides | Ms. Postlethwaite's Human Geography Page | Scoop.it
In recent decades the state allowed logging — with restrictions — on the plateau above the Snohomish County hillside that collapsed in last weekend’s deadly mudslide.

Mijnbouw en aardverschuivingen, een goede combinatie ...... 

PIRatE Lab's curator insight, April 7, 2014 11:48 AM

There are several reasons for mudslides--some are purely a result of physical geography and others are related to land use patterns.  This last week's mudslide in Washington state was a combination of the two and although this impacts one place (see on map), it is a good teaching moment to discuss the environmental impacts of land use patterns and resource extraction projects.  As seen in this interactive, the river was cutting at the base of the hill, while loggers were clear-cutting at the top of the mountain.  Trees help prevent erosion as the roots hold the soil in place--a critical piece to the puzzle in a very rainy climate.  With $1 million worth of timber on the slope, logging companies persisted despite objections from the Department of Natural Resources and some restrictions (but in hindsight, those restrictions clearly were not enough).

Questions to Consider: Other than economic worth, what other ways are there to value and evaluate the environment?  How could this landscape have been protected and managed better or was this mudslide inevitable?

This is a brief introduction to what geographic information systems are.  This is not a tutorial on how to use it, but a conceptual overview on the potential uses and applications for GIS.

Useful for understanding the use of GIS and differences with GPS.
