Phosphorus limitation of ecosystem responses to global change
The Jasper Ridge Global Change Experiment (JRGCE) began an experiment located near its main field plots to test a new hypothesis concerning responses of ecosystems to environmental change. The hypothesis is based on six years of field results in which elevated CO2 had a small negative effect, or none at all, on plant biomass, together with a reversal of this pattern--enhanced production under elevated CO2--in plots burned by a wildfire in 2003. The team hypothesizes that phosphorus availability limits the response of California grassland to elevated CO2, a limitation that can be temporarily reversed when fire liberates phosphorus that was trapped in aboveground litter.
This study tests the P-limitation hypothesis by examining ecosystem responses to additions of nitrogen, CO2, and phosphorus, applied singly and in all possible combinations. This factorial approach allows one to ask whether, for example, the response to elevated CO2 differs depending on whether nitrogen and/or ... Read More
Jasper Ridge Biological Preserve Celebrates 40 Years
This year marks the 40th anniversary of the founding of Jasper Ridge Biological Preserve. Since 1973, research conducted at the preserve has transformed fundamental ecology science.
Now, interdisciplinary studies are providing more guidance than ever on how to apply that work to help conserve the planet.

Chris Field speaks at U.S. Senate hearing on climate change
Jasper Ridge Biological Preserve faculty director Chris Field spoke August 1 at a U.S. Senate hearing where
he warned of the increased risk of heat waves, droughts and heavy precipitation due to climate change.
"It is critical to understand that the link between climate change and the kinds of extremes that lead to disasters is clear," said Field in his testimony before the Senate.
Field is a Senior Stanford Woods Institute for the Environment fellow, Stanford professor of biology and environmental Earth system science, and director of the Department of Global Ecology at the Carnegie Institution for Science.
He is also co-chair of an Intergovernmental Panel on Climate Change (IPCC) working group.

Performance artist Ann Carlson offers unique view of Jasper Ridge
Jasper Ridge Biological Preserve recently hosted Picture Jasper Ridge: A Performance Hike –
a 70-minute "tableau vivante" experience combining a walk in the preserve with actors recreating historic photos near the actual locations where the photos were taken.
Picture Jasper Ridge is the work of Ann Carlson, an American dancer, choreographer, and performance artist. Carlson is currently in residence with
the Stanford University Drama Department for the
2011-12 academic year and is the inaugural visiting artist at the Jasper Ridge Biological Preserve during the Winter Quarter.

Successful prescribed burn at JRBP
The California Department of Forestry and Fire Protection (Cal Fire), in collaboration with Jasper Ridge Biological Preserve,
conducted a small, prescribed burn inside the preserve's main entrance on Sand Hill Road on Monday, July 18, 2011.
The prescribed burn was confined to just 1.2 acres of grassland and provided a range of benefits for management and research.
More information, including videos and photos, is available at jrbp.stanford.edu/fire.php.
