Lichen Loop: Exploring Lichens as Indicators of Air Quality

Date: 25-Feb-2017
Capacity: 25 (92% booked)


Join us for a walk in Forest Park with Hannah Prather, a PhD student at Portland State University. Hannah will be sharing her research from the Portland Metro area including her tree canopy lichen studies and what those studies are telling us about our regional air quality. Because many people missed the first walk with Hannah in December due to the snow-storm, we are so excited that Hannah offered to lead another hike!

Hannah will also teach us the basics of understanding lichens and how to identify a few of the more common macro-lichen species in the field, including species which can be used as bio-indicators of air quality. 

Hannah will take us for a 1.5 mile walk up towards Pittock Mansion, an area where she gathered data for her research.

When: Saturday, February 25th. 9 am to 12 pm

Where: Upper MacLeay Trailhead on NW Cornell (Where the Wildwood Trail crosses Cornell Rd just below the Audubon Society)

There is a parking lot on the north side of the road. Carpooling is encouraged. 

If you have them, feel free to bring guidebooks, hand lens, and magnifying glass. Also, bring your field notebooks and cameras to make notes and capture pictures of what we find.
