Flora fauna weeds

Native plants/flora

There are four vegetation communities present in the South Lawson Park bushcare site:

1. Woodlands. There are two main groups of open canopy tree community:

A. Eucalyptus piperita (Sydney Peppermint) – Angophora costata (Smooth-barked Apple); and

B. Corymba gummifera (Red Bloodwood) – Eucalyptus sieberi (Black or Silvertop Ash).

These types of woodlands are the most extensive form of vegetation present on the site and the forest trees of these two communities have evolved to grow on sandstone based soils that are of average to low fertility and very well drained.

2. Blue Mountains Riparian Complex. Sections of the Lawson Creek bank have richer than average soils due to a high content of deposited alluviums. They support moisture loving plants such as ferns and Black Wattle, as well as Woodland plants such as eucalypyts, banksias, hakeas, acacias and tea-trees.

3. Blue Mountains Swamps. The sedges, ferns and shrubs of the swamps grow in peaty  soils that contain large amounts of vegetative matter and are located in permanently damp situations.

4. Rainforest. The small patch of rainforest is dominated by the tall tree Ceratopetalum apetalum (Coachwood). The rainforest plant community also enjoys the richer Lawson Creek bank soils.

A good reference book for Blue Mountains flora is “Native Plants of the Blue Mountains”, by Margaret Baker and Robyn Corringham, Three Sisters Publications. Available at good local bookshops. It’s very reasonably priced and has great illustrations and lots  of information about the local natural environment.

A great way to become familiar with the flora and weeds of the Lawson Creek catchment is to view our eight minute film, Bushcare Blue Mountains: South Lawson Park:  https://vimeo.com/verahong/south-lawson-bushcare . Many thanks to Vera and Craig at Seconds Minutes Hours Productions for their wonderful cinematography.

The State and Commonwealth listed Vulnerable species Persoonia acerosa (Needle Geebung) and the endemic species Acacia ptychoclada, a wattle, have been recorded on the site.

The purpose of bushcare is to contribute to the  preservation of the naturally evolved bushlands and ecosystems of a region. So for the purposes of bushcare, a weed is considered to be a plant that is growing in or is likely to spread into but is not a naturally evolved species of the local and regional bushland and ecosystems. So a weed can be an overseas species, or an Australian native species that has been transferred into an ecosystem to which it does not naturally belong.

Some, but not all, introduced plants, in the absence of the natural population control factors of their original ecosystem, grow and spread so vigorously that they destroy many of the locally and regionally evolved plants that constitute the local ecosystem, significantly altering and even destroying the functioning of that ecosystem. This type of weed may be declared a “Priority Weed” or a “Weed of Regional Concern” under the NSW Biosecurity Act 2015 and public authorities and private landowners are required to manage the weed in a specified way.

This listing of site weeds is not meant to be exhaustive.

The most prevalent and threatening weeds located on the site are:

Arum lily;

Broom, a highly invasive shrub or small tree;

Creeping Buttercup, a spreading herb found in damp situations;

English Ivy, a smothering climber;

Gorse, a highly invasive shrub (two plants);

Japanese Honeysuckle, a vigorous climber;

Juncus microcephalus, a perennial sedge found in damp situations;

Montbretia, a herb that colonises stream banks and damp areas;

Privet (both small and large leaved varieties); and

Pussy Willow.

Smaller quantities of Cootamundra Wattle, Himalayan Honeysuckle, Butterfly Bush (Buddleia davidii), and Turkey Rhubarb are present and under varying degrees of control.

Weedy grasses are also present and undesirable and are treated when encountered.
