Sub-alpine wetlands of the Barrington Tops are in a reasonably healthy condition, despite low snowfalls so far this winter.
The National Parks Area Manager Anthony Signor, said there have been a few light dustings recently but heavier falls are not expected this weekend.
Mr Signor said the snow brings moisture to the High Country vegetation and wetlands.
"One of the things about the snowfall is its role in recharge and determining where various species will occur on the plateau in the High Country," he said.
"But recharge of the water table in our sub-alpine wetland in particular is one of the roles that snow performs.
"It certainly has a role to perform in terms of where different vegetation types will grow."
Mr Signor said the wetlands support an endangered population of the native broad tooth rat, which is being carefully monitored.
"We have a monitoring program in terms of surveys for the population and associated with that is an effort to control predation from foxes," he said.
"The monitoring to date shows that that population is reasonably stable and we are getting on top of the foxes too so that's good news for the threatened species."
