Historical Ecology

Historical Ecology synthesizes diverse historical records to learn how habitats were distributed and ecological functions were maintained within the native California landscape. Understanding how streams, wetlands, and woodlands were organized along physical gradients helps scientists and managers develop new strategies for more integrated and functional landscape management. more >

News and Notables


Letitia Grenier, Robin Grossinger and Jeremy Lowe will be presenting at "New Approaches for Responding to Climate Change in the San Francisco Bay-Delta "


An explanatory series focusing on one of the most complex issues facing California: water sharing. And at its core is the Sacramento-San Joaquin Bay Delta. Stay with kcet.org/baydelta for all the project's stories.


Resilient Silicon Valley is a project of the San Francisco Estuary Institute to build the science-based framework needed to guide the design of and investments in regional ecosystem health.


How does responsible stewardship of a cultural landscape balance history and ecology?


Several new CRAM training tools and enhancements are now available on the CRAM website and EcoAtlas.


In partnership with the San Francisco Bay Joint Venture (SFBJV), SFEI/ASC developed a new interactive map to display active and completed SFBJV partner projects throughout the region.


The Riparian Zone Estimator Tool (RipZET) is a GIS-based decision support tool under development for estimating riparian zones at the watershed and/or project scale. The tool provides reach-scale functional riparian width estimates based on average height of mature riparian vegetation, the steepness of hillslopes adjacent to the channel, and the floodplain inundation extent for large storm events. The appropriate width estimate for a reach is then determined based on the riparian functions associated with different channel types, which range from steep headwater channels to low-gradient, meandering channels with broad floodplains.


The recent EcoAtlas release delivers new functionality and enhancements to the Landscape Profiler, a tool that summarizes ecological information at various spatial scales for assessment, planning, and reporting. Users can upload a KML file, edit the boundary, and save a polygon for their area of interest. Additional datasets are summarized in the Landscape Profile Report, including the revised 2011 National Land Cover Dataset, eelgrass survey data along the coast from Humboldt Bay to San Diego Bay, and percentages of languages spoken from the US Census data. A date slider helps to visualize the extent of eelgrass surveys over time.
