Herbivory on soap plant (Chlorogalum pomeridianum)

Soap Plant, Chlorogalum pomeridianum, is an abundant, large bulb plant in many areas of Jasper Ridge. It is subject to substantial herbivory of both its leaves and inflorescence. In February 2009 Rodolfo Dirzo began a study of herbivory on this species at 4 sites across Jasper Ridge.

Jasper Ridge Bird Monitoring Program

The Jasper Ridge bird monitoring program consists of two separate but complementary surveys whose goal is to create a body of data that can be used to detect trends in many aspects of avian ecology, both within specific habitats and for JRBP as a whole.

Jasper Ridge Eddy Flux station

The Jasper Ridge Eddy Flux Site continuously measures fluxes of water vapor and carbon dioxide between the grassland and the atmosphere, in addition to monitoring a wide array of meteorological parameters such as wind, temperature, net solar radiation, and barometric pressure.

Jasper Ridge Global Change Experiment

The Jasper Ridge Global Change Experiment (JRGCE) studies the response of California grassland to 4 environmental factors changing globally--warming, nitrogen deposition, elevated carbon dioxide, and increased precipitation--applied in a full-factorial design.

Monitoring of flow and water quality

San Francisquito Creek begins in JRBP at the confluence of Bear Creek and the outflow from Searsville Lake. It flows more than 12 miles to the Bay and is unchannelized for nearly half its length.

Oak regeneration ecology

During the summer of 2009 Rodolfo Dirzo began a long term study of the impact of herbivory by large mammals, principally deer and rabbits, on 3 oak species. For the study, Rodolfo identified 75 pairs of oak seedlings for each of 3 species: Quercus agrifolia, Q.lobata, and Q.
