Elegans is one of the more difficult weeds in Sherbrooke Forest because
...has no predator to control it
...growth is rampant
...layers easily so that when trees or branches fall on it , we get a profusion of new plants appearing from wherever it touches the ground. Also, since the branches can grow to some six metres in length, they tend to sag.
The tips often reach the ground and the layering process starts again.
In May 1999 we took a deep breath and began to tackle a 9 hectare section of the forest adjoining the Trestle bridge and Nation Road , hitherto quite neglected and some 60% Cestrum.
We weren't too sure we'd ever finish it but on the principle of "nothing ventured , nothing gained" began a demolition process on a weekly basis.
Taking a break occasionally to remove Cestrum from other sites, we persevered with yearly follow-up weeding and note with pleasure that the Cestrum cover is now only round about 2% at the Nation Road site.
Below are a series of photos
featuring some of the work that has been carried out to reduce the Cestrum problem.

Note the ideal weapon - a long machete!

Lipscombe Break. The demolished weed is lying at the

Note the growing Cestrum on the left hand side in the
"before" photo. It became the piled-up heap in
the left forefront of the "after" photo. We're
not sure why Mick is smiling after working THAT hard!
Firstly contemplating a Cestrum
clump, then the satisfactory result after pulling/cutting it
out. The clump in front of the men in the
"after" photo is a pile of demolished cestrum.

an ex ranger (now volunteer). Then (after), NO Cestrum

side of these photos to see the difference.
