DFW conducts precautionary brown tree snake survey on Saipan

The CNMI Division of Fish and Wildlife (DFW) Brown Treesnake Program received an unconfirmed report of a February 15th, 2026, observation of a snake on Saipan. In response, DFW initiated precautionary brown treesnake surveys and trapping in the immediate area and worked closely with US Fish and Wildlife and US Geological Survey to continue surveys and monitoring where the report originated. These efforts are being undertaken out of an abundance of caution to verify that no brown treesnakes are present. There is currently no confirmed evidence of the presence of a snake.

Reports of potential brown treesnake sightings are extremely important and are treated with the highest priority. A rapid and timely response to such reports is the most effective way to safeguard the CNMI’s unique native species and ecosystems. Biologists are actively reviewing data collected to determine what actions are warranted.

Residents may notice survey personnel in high-visibility shirts working in the San Vicente, Kanna Tabla, and As Lito areas as part of this effort. Teams are placing flagging during the day and conducting visual surveys at night using high-powered headlamps. These survey activities are scheduled to continue throughout the week of April 6th.

If you see any unusual snake-like animal, report the sighting to 670-28-SNAKE (287-6253). If possible, note the exact location and take a picture to assist responders. (PR)
