Tenure

Sydney Catchment Authority Special Area

Description

Button Grass (Gymnoschoenus sphaerocephalus) is the dominant plant and has formed a dense cover in the swamp. Lepidosperma limicola and Leptospermum juniperinum, Baeckea linifolia and Grevillea acanthifolia occur as well and usually grow from amongst the Button Grass. The margin of the swamp grades to open forest with Eucalyptus piperata and E. sieberi the dominant species. Exotic pine trees (Pinus radiata) have been planted extensively nearby and in some places these plantations abut the swamp. Pine trees have colonised parts of the open forest and the occasional individual is growing in the swamp.
Surrounded by forest, some large shrubs in amongst sedges (invading swamp)
Very high tussocks
Intersected by powerline corridor

Possible threats

Access
Runoff from roads
Disturbances associated with maintenance of service corridors/easements
Residential development in adjacent or nearby areas
