The Jasper Ridge Eddy Flux station provides data that can be used to address questions that span many different times scales and spatial scales: 1) how do different ecosystems respond to environmental changes? 2) how do changes in ecosystem metabolism feed back to affect the environment?

Originally intended as a drinking water reservoir, Searsville Lake has always been too turbid for that purpose, thanks to the high input of sediment from the largest of the lake's five tributaries, Corte Madera Creek.

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.

For plants, the soil environment is a major habitat factor and can be extremely important in plant speciation. Jasper Ridge is home to an extensive serpentine outcrop occupied by two superficially indistinguishable species of Lasthenia(Asteraceae), L. californica and L. gracilis.

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.

Oaks of central California vary considerably in acorn production from year to year, making them good candidates for determining what factors regulate acorn production and whether trees are synchronized in the ups and downs of their acorn yield.

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.

A very precise and accurate GPS (global positioning system) can be vital to understanding earthquake hazards because it can reveal information that is invisible to seismometers--crustal movement that occurs over long time scales and is associated with crustal deformation and buildup of strain alo

A prominent feature along Trail 1 is the site where the Zoology Cabin once stood, now marked by the remains of the fireplace that was at the rear of the cabin.

Drought in California and much of the western United States has been severe enough over the last two decades to be considered a mega-drought, possibly the worst in a millenium. Prolonged drought such as this reduces agricultural yields, and increases forest mortality and wildfire risk. Despite
