A reminder for all our visitors, pets (non-service animals) are not allowed on refuge trails, boardwalks, or in the visitor center . Pets are only allowed to walk along Pleasant Plains Road and in parking areas on a leash not exceeding 10 feet at all times. Unleashed dogs have the ability to spread diseases to wildlife, as well as injure wildlife/other visitors.

Service animals (those that have been individually trained to do work or perform tasks for an individual with a disability; the task(s) performed by the service animal must be directly related to the person’s disability) are allowed in all areas of the refuge that are open to the public, including refuge parking lots, roads, trails, and visitor centers.

Thank you for your cooperation (photo: unleashed dog and owner trespassing off-trail at the Great Swamp NWR).

The U.S. Wildland Fire program will be attempting (dependent upon favorable weather conditions) a prescribed burn along Pleasant Plains Road tomorrow (April 7th) and Wednesday (April 8th) to improve wildlife habitat and lessen wildfire risk. The entirety of Pleasant Plains Road will be closed beginning tonight at 7PM. The entrance to the refuge at the intersection of Wood Duck Way and Lees Hill Road will reopen at 9:30AM tomorrow so that the Visitor Center can operate with normal hours. The rest of Pleasant Plains Road will remain closed on Tuesday, Wednesday, and possibly on Thursday to ensure visitor and firefighter safety. Thank you for your patience and understanding.

Prescribed burning removes invading trees and shrubs that would otherwise overtake the fields, helps control non-native plants, and promotes the growth of native warm-season grasses that provide important wildlife habitat. The operation will only take place under favorable weather conditions to keep the fire and smoke manageable.
