TRA has developed hands-on expertise in habitat enhancement, revegetation, and restoration projects.

Our staff expertise in biology and landscape architecture provides the technical knowledge to design, oversee installation and monitor projects geared toward the ecology of each particular site. Much of our past restoration work has been in concert with efforts to preserve an endangered or threatened plant or animal species. TRA understands the complexities of developing a restoration plan in a regulatory framework, as well as the complexities of implementing the plan in the field.

We have completed a variety of habitat restoration projects, including riparian revegetation plans in creeks in the San Francisco Bay Area, revegetation plans addressing rare plant species (particularly serpentine), bank stabilization and restoration in steelhead and California red-legged frog habitat, modeling habitat parameters for enhancement of forest grove habitat for the Monarch butterfly, control of non-native exotic plants and grassland restoration to enhance endangered butterfly habitat, and the restoration and creation of freshwater marsh. TRA staff has experience with a variety of habitats, including serpentine grassland, freshwater marsh, central coast riparian scrub, coastal prairie, coastal bluff, and northern maritime chaparral.

With an overall goal of achieving self-sustainability and minimizing adverse environmental impacts, each project is carefully analyzed to determine ecological needs and permit requirements. We are familiar with the range of revegetation and habitat restoration techniques. These include biological surveys, soil tests, controlling or removing unwanted weedy species, erosion control, collecting and preparing seed of desired species, preparing landscape architectural plans, providing an adequate substrate to grow desired species, applying seed or planting contract-grown container plants, and monitoring the results.
