Change in Trail Fauna Over 10 Years

Postby postholer » Fri Nov 18, 2016 3:04 pm

Here you'll find land cover change over a 10 year period for various trails.

The purpose is to bring awareness to the changing state of fauna over the length of these popular hiking trails. There are 2 columns. The Miles column is total trail miles this land cover condition affects. The Land type column indicates the type of changing condition.

Looking at the PCT you'll notice that 1631.3 miles of trail was unchanged from Evergreen Forest to Evergreen Forest. You'll also note that 8.2 miles went from Evergreen Forest to Shrub/Scrub and 12.9 miles went from Evergreen Forest to Grassland/Herbaceous

Data is from MRLC. We look at an approximately 600 foot swath, staggered over the trail and use the predominant land cover type (mode).The 10 year change period is from 2001 to 2011(updated 2014). With any luck the MRLC will have a 2016 data set soon and we'll update for that.
