Glencoe Swamp is a river red gum and black box floodplain depression situated next to Thule Lagoon, near Barham NSW. The wetland is 2 Ha in size and supports a diversity of aquatic vegetation including Canegrass. The wetland has the potential to provide habitat for the endangered southern bell frog (Litoria raniformis), and has recorded the threatened grey-crowned babbler (Pomatostomus temporalis).

Water delivery to the wetland focusses on providing a suitable wetting and drying regime to maintain the health of the black box trees and provide suitable habitat for the southern bell frog.

During 2021-22, environmental water was delivered for the first time to the wetland. The watering event delivered during autumn, primed up the system to potentially support the southern bell frog which occurs in the surrounding area.

Prior to water being delivered through the Environmental Water Trust, the wetland had remained dry for some years. Working closely with the landholders to manage water delivery, Glencoe Swamp will be watered during autumn and spring to improve habitat and for frog recruitment.

Following watering in 2021-22 four frog species were recorded including the Perron’s tree frog, spotted marsh frog, barking marsh frog and plains froglet, the southern bell frog has not yet been detected, though call recorders are in place to record their potential arrival. Vegetation response at the wetland has seen the extensive emergence of common spike rush (Eleocharis acuta), and it is expected that with further waterings the diversity of plant species will increase over time as the aquatic seedbank and subsequent vegetation community is revitalised.
