Representative Projects

Fernandez Ranch Management Plan

Fernandez Ranch incorporates 700 acres of grasslands, oak woodlands, and riparian corridors representative of northern Contra Costa County's beautiful open lands.


<em>Pseudobahia</em> Status Surveys

VNLC was awarded a USFWS grant to conduct updated status surveys of two federal and State listed species: Hartweg's golden sunburst (Pseudobahia bahiifolia) and San Joaquin adobe sunburst (Pseudobahia peirsonii).


California High Speed Rail Mitigation Preserve Project

VNLC undertook a first-of-its kind landscape-level restoration of a formerly leveled vernal pool landscape. Based on LiDAR data, historical aerial photos, and extensive soil pit studies, we designed a complete pool-swale-mound system.


Lights Creek Botanical Survey Plumas National Forest

Vollmar Natural Lands Consulting conducted surveys for rare plants, invasive weeds, and sensitive habitats within 9,600 acres on the Mt. Hough Ranger District, Plumas National Forest.


Montezuma Wetlands On-Site Mitigation Preserve

The Montezuma Wetlands Project is using dredge material from SF Bay to restore tidal marsh within diked baylands at a site along the edge of Suisun Bay. This project incidentally impacted western burrowing owl habitat and several man-made seasonal pools supporting listed shrimp species.


Concord Naval Weapons Station Surveys

VNLC conducted botanical resource surveys and reconnaissance wetland surveys on the 5,000- acre inland portion of the Concord Naval Weapons Station, which was transferred from the U.S. Military to the City of Concord.


Open Space Preserve Aquatic Habitat Surveys

VNLC conducted pond and stream surveys for special-status reptiles and amphibians at six large preserves owned or managed by the Santa Clara Valley Open Space Authority.


La Purisima Ranch Management Plan And Conservation Bank Establishment

The 2,700-acre La Purisima Ranch is located in the Purisima Hills of northwestern Santa Barbara County.  The predominant vegetation communities on the Ranch are coastal sage scrub, oak woodland, and native and introduced annual grasslands.


Caltrans “Madera Pools”  In-House Mitigation Bank

Vollmar Natural Lands Consulting is establishing a multi-species vernal pool/seasonal wetland mitigation bank for Caltrans on a 200-acre property located northwest of Fresno, California. Caltrans will use the bank as an in-house source of mitigation for impacts from transportation projects in the San Joaquin Valley.


Constructing Vernal Pools For Ecological Function

VNLC is conducting a two-year study being funded by the Bureau of Reclamation under the Central Valley Improvement Act grant opportunity (with technical oversight by the U.S. Fish and Wildlife Service) that is examining historic trends and success of vernal pool restoration and creation at ten project sites (~500 pools) in the Sacramento Valley.
