Aspen Research With Bobette Jones

Friday, March 7, 2014; 7:00-8:30 PM

Madelyn Helling Library Community Room, Nevada City

Suggested Donation: $10


Quaking aspen are an iconic and keystone species of mountain forests in the West. They are famous for their stunning white bark, fluttering leaves and brilliant fall colors. The Basque shepherds in the Sierra used them for their carvings of female fantasies. Their well documented decline in the Rockies and Sierra Nevada mountains is a worry to those concerned with the long-term biological diversity of the alpine areas of these mountains.

New research published on December 20, 2013 describes several efforts by the US Forest Service to reverse the trend of decline at two
research sites in the Sierra.

Bobette Jones of the Pacific Southwest Research Station will be in Nevada City March 7, 2014, at the Madelyn Helling Library Community Room to make a presentation about her work in the Lassen area.

She will describe the natural history of aspens, the causes of their decline and the 10 year studies she has been involved with in restoring trembling aspen in their native habitat.

SYRCL is involved locally in a restoration project at Loney Meadows and this will be an opportunity to reflect on how PSW Research Station’s studies are relevant to our local aspen forests.

The 2013 study called Aspen Stands: Restoring and Managing was published in the online peer-reviewed scientific journal PLOS and is available on line at:
