Rain and landslides

The first few months of 2022 saw rain, rain and more rain. The weeds were growing faster than we could treat them, and then on 6 March part of the road to Narrow Neck (Glenraphael Drive) washed away.

The landslide occurred just inside the national park boundary, about 400m from Cliff Drive. Access to all vehicle and foot traffic was closed by the council and NPWS. Given the size and location of the landslide, it may be many months or more before the road is opened again. This will give a heavily used area some much needed rest.

Our bush care group no longer had access to the main access road that ran through the centre of our site. This was a chance to treat the northern perimeter of our site along Cliff Drive.

The Cliff Drive road verge has a strip of exotic grasses, which we won’t bother treating, then mostly native vegetation further in. We will look to remove or treat all exotic plants in this zone.

On our monthly sessions in April, May and June we have been treating small outbreaks of woody weeds along the bushland bordering Cliff Drive such as cotoneaster, blackberry and broom, and grassy weeds such as Parramatta grass and kikuyu.

This patch of kikuyu next to the road probably originated from illegally dumped grass clippings.

It was a tedious job but thankfully it was not a large patch.

Our treatment involved cutting each stem then quickly dropping a dab of glyphosate on each cut stem within a few seconds.

Applying the glyphosate to each stem. The red spots are stems that are already treated.

And we were delighted to find a flowering Greenwood orchid.

A nice surprise! A greenhood orchid in front of the trowel.
