Last week (5-18-12), most of the students in 7th grade science at Blatchley Middle School in Sitka went to the Starrigavan Valley to help government biologists monitor the health of the stream.

This was no ordinary field trip: It’s part of an ongoing project where students collect permanent data that will be used by Forest Service managers to make decisions about the future of the valley.

KCAW student reporter Maya Reda-Williams documented the project, and sent this audio postcard.
