Acoustic Bat Monitoring

Long-term studies of organisms and the environment may help detect threats to both individual species and ecosystems as a whole. Monitoring bats can provide early warning of potentially negative changes in our local ecosystem such as habitat fragmentation and loss of habitat.

Annual monitoring of the 2017 “low-flow crossing”

San Francisquito Creek and its tributary creeks are habitat for the threatened, local form of migratory steelhead trout, Central California Coast steelhead.  Prior to 2017, fish passage in the uppermost portion of San Francisquito Creek within Jasper Ridge Biological Preserve was constrained by a

Bay Area Regional Deformation Network (BARD) Station, JRSC

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

Bird Monitoring and Surveying 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.

Birds of Jasper Ridge

The purpose of this project is to document the avifauna of Jasper Ridge Biological Preserve with a searchable database of high quality photographs of birds in their natural habitats within the preserve.

Camera trap monitoring of wildlife

Wireless digital camera traps are providing unprecedented and detailed information on some of JRBP's big unknowns, such as the abundance and behavior of large predators and the nature of biological corridors linking JRBP to other areas.

Ecological specialization of cryptic species on a serpentine outcrop

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.
