Sycamore Alluvail Woodland Habitat Mapping and Regeneration Study Released (News)

California sycamore (Platanus racemosa) is an iconic native tree species found in California and northern Baja California. The health and regeneration of California sycamore have been substantially affected by a wide range of factors, including hydrologic modifications of creeks, hybridization with London plane tree (Platanus x hispanica), and anthracnose.

Sycamore Alluvial Woodland Habitat Mapping and Regeneration Study (Project)

This study investigates the relative distribution, health, and regeneration patterns of two major stands of sycamore alluvial woodland (SAW) in Santa Clara County, representing managed and natural settings.  Using an array of ecological and geomorphic field analyses, we, along with our partners at H.T. Harvey, discuss site characteristics favorable to SAW health and regeneration, make recommendations for restoration and management, and identify next steps.

Understanding Change in Primary Production at a Landscape Scale in the Delta (Project)

Sixteen local and national experts met for a three-day workshop hosted at SFEI to develop a plan that will for the first time quantify primary production in the Sacramento-San Joaquin Delta, both historically and today. During the workshop (October 28-30), scientists with expertise in primary producer groups, hydrodynamics, and food web dynamics integrated existing data, scientific literature, and best professional judgment to build a new synthesis of past and contemporary production and its ability to support to support the base of the Delta food web. Building upon SFEI's work in the Delta Landscapes project, and funded by the Delta Science Program and USGS, this is the first stage of a planned three-phase project.

Lower Walnut Creek Historical Ecology Study (Project)

During the mid-19th century, the lower Walnut Creek watershed was a landscape dominated by extensive wetlands, meandering creeks, and grassy plains. The marshes, sloughs, and meadows provided habitat and food for a huge number of wildlife species ranging from grizzly bears and elk to clapper rails and steelhead. Over the past 150 years, urban development, diking and filling of wetlands, and channelization of streams has resulted in dramatic changes to the watershed, and much of the historical habitat has been lost.

Lower Novato Creek Vision Just Released! (News)

SFEI recently released a resilient landscape vision for lower Novato Creek that incorporates habitat restoration actions into flood risk management. The vision, developed in coordination with a team of regional science experts, highlights opportunities for restoring and sustaining vital tidal wetland habitats around lower Novato Creek while supporting a high level of flood protection under rising San Francisco Bay water levels.
