Environmental Review

($275/project; add $75 for each additional USGS Quadrangle Covered)

The Natural Heritage Program currently tracks over 1100 rare and endangered plant and animal species as well as hundreds of conservation sites across the state. This information is collected through ongoing research and field investigations by the Division and other scientists from across the State, as well as from scientific literature, museum collections, and other sources and is continually analyzed and updated. Natural Heritage data is not only important in identifying areas of ecological significance for conservation and restoration activities, but is also a valuable tool in the environmental review process.

For environmental review planning, the DNA encourages using the Interactive Rare Species Database. However, if you would like site-specific data of known state and federal concern plant and animal species, ecologically significant sites, and certain conservation managed lands, we can perform such reviews for $275 per project. DNA staff will prepare and send to the requesting entity a list and/or map of rare species documented within a one-mile radius of the project area, as well as a list of species documented from the surrounding area within four miles. Larger projects and linear projects that cover an area greater than a 4-mile radius shall be charged $75 for each additional USGS 1:24,000 quadrangle included in the project area.

Please use the Online Environmental Review Request form to submit your review request (link below). Data requests are usually filled within 15 working days and e-mailed to the receiving entity with an invoice for payment if payment is needed. NOTICE (8/19/2020): In response to a substantial increase in requests for environmental reviews we are temporarily increasing our processing time to 30 days. We apologize for any inconvenience this may cause. You may contact the Environmental Review Coordinator at if the increased processing time will adversely affect your project timeline. Please note that we intend to return to the normal processing time as soon as possible.

Please note that we have revised our notification system following online form submittals. Rather than processing instantaneous email notifications as before, the system now generates email notifications in batches every four hours. After submitting a request, you will receive a confirmation email within four hours.
