User's notes
Umbrella sedge solarized with builders plastics; this is an experiment to control large numbers of umbrella sedge in a sensitive (frog) area where the use of herbicide is difficult and umbrella sedges are too many to be removed by hand; see also record of https://canberra.naturemapr.org/sightings/4653230. The partially removed plastics show the pale leaves that lost the chlorophyll but are not dead. The plastics might need to be in place for a whole season and Umbrella Sedge should be checked from time to time.

I suggest to leave the plastics for a whole season including spring and summer.

My experience is that frogs would use any protective cover including exotic Umbrella sedge. In this respect they are opportunistic - like little woodland birds which use blackberry for cover or firethorns for building nests .... We therefore covered only half of the umbrella sedge that grows at the fringe of this old farm dam.
