Wildlife Species Surveys

Endangered and threatened wildlife species surveys are often mandatory elements of development projects.

Endangered species and threatened species must be surveyed and protected during project planning and construction activities.  The in depth knowledge and extensive experience of WRA’s wildlife biologists enables us to accurately and efficiently identify the presence or absence of rare species in a project area, assess habitat values, quantify population abundance and distribution, prepare impact mitigation, and secure required permits.
