We perform Habitat Assessments for proposed development and to determine the suitability of potential mitigation lands. CEC is the Land Manager for conservation easements, and we have performed biological surveys and conducted compliance monitoring in numerous habitat types.

We have served as the “Avian Resource Lead” and “Raven Compliance Manager,” performing surveys and monitoring support on multiple utility-scale renewable energy sites and linear utility projects.

Corvus Ecological Consulting performs wildlife surveys and conducts Habitat Assessments and population analysis. This work includes both research and development focused projects. Surveys can be species-specific or general; based on project needs, goals and objectives. Do not hesitate to contact CEC for a project consultation to ensure that you are getting the most cost-effective approach to conducting environmental surveys and habitat assessments.


Corvus Ecological Consulting has experience performing construction monitoring and compliance oversight on a multitude of development-based projects. CEC has performed construction monitoring on utility-scale renewable energy projects as well as linear utility corridors. Our efforts and involvement have resulted in the successful completion of numerous high-profile projects without delays or unnecessary costs due to natural resource compliance issues. Let our expertise facilitate project development while maintaining resource protection.


Many biological resource issues are not realized until a project has been fully constructed and enters into an operation and maintenance phase. Additional costs associated with operation phase tasks can catch Operators and Owners off-guard. Collected data and impact assessments during this period can be an important factor used to inform future efforts within the industry. Let Corvus Ecological Consulting provide you with a cost-competitive quote for Avian Fatality Monitoring and other operation phase biological resource tasks that can help avoid unintended consequences down the road.

Our Projects

The following includes an assortment of current and recent projects.


Corvus Ecological Consulting is the Land Manager for a conservation easement in Kern County, California. Management duties for the Alta Oak Creek Mojave Mitigation Conservation Area are intended to ensure that these lands continue to maintain their core conservation values over time. The conservation easement includes two properties near the town of Mojave, in the western Mojave Desert and foothills of the Tehachapi Mountains. Species of interest on these properties include Mojave desert tortoise and Bakersfield cactus.


Since 2013, Corvus Ecological Consulting has performed Common Raven and raptor nest identification and monitoring within Desert Wildlife Management Areas, lands administered by the National Park Service and desert tortoise Critical Habitat Units in Southern California. These projects aim to study the interaction and effects of Common Ravens on desert tortoise populations, while gaining a better understanding of raven population dynamics and human-provided subsidy use. Project results can be used to inform the “Environmental Assessment to Implement a Desert Tortoise Recover Plan Task: Reduce Common Raven Predation on Desert Tortoise” issued by the United States Fish and Wildlife Service, March 2008.


Corvus Ecological Consulting performs habitat assessments within land parcels that are being considered as habitat mitigation to offset the impacts of utility-scale renewable energy development in California’s eastern deserts. These assessments ensure that habitat characteristics of the mitigation land are of a suitable quality to offset habitat loss due to project development.


During construction of the Stateline Solar project near Primm, NV, Corvus Ecological Consulting worked as a subcontractor to Ironwood Consulting, Inc., performing avian resource duties. CEC wrote project-specific management plans including the “Bird and Bat Conservation Strategy.” CEC was also responsible for conducting Avian Point Counts surveys, Migratory Bird Surveys, Golden Eagle Territory Occupancy and Nesting Surveys, Burrowing Owl Surveys, Nesting Raven/ Raptor Surveys, and Preconstruction Nesting Bird Surveys in addition to Incidental Avian Fatality Monitoring.
