Samples of the plants listed below were collected throughout the survey but were later misplaced. Speculation can be made about certain species but without the flower or fruit it is difficult to conclude with a positive identification. A description of the individual plant species were recorded on the initial survey sheet and it is necessary to list them below.

The flora survey only shows plant species present. The survey does not include details on the density of each plant species in the area.

(1) Pultanaea sp. - small leaves; scattered minute hairs on both leaves and stem; low groundcover up to 40cm high; not in flower; suggested species - Pultanaea microphylla.

(2) Eucalyptus sp. - reddish stringybark.

(3) Dichelachne look-a-like - has the same form as Dichelachne but the flower head it not as feathery as the Dichelachne species.

(4) Leptospermum sp. - leaves possess three main veins running parrallel. These veins are prominent along the leaf; not in flower.

(5) Zieria sp. - leaves are a little more rigid than Zieria smithii; small hairs are also present on the leaves; not in flower; suggested species - Zieria pilosa or Zieria murphyi.

(6) Sedge sp. - a distinctive globular terminal seed head.

(7) Sedge sp. - with a paspalum-like/ehrharta-like seed head.

Emergent Ink Weed species were weeded out approx. six months after the fire (before they were able to seed) and have not returned on the site.

The flora survey only shows plant species present. The survey does not include details on the density of each plant species in the area.

The situation following a fire is one similar to the beginning of succession. Succession is where one group of plants germinate to provide perfect nursery conditions for a host of other native species. Following a fire, native grasses and vines are the first to emerge, followed by shrubs and tree seedlings. These take many years to mature.

It is envisaged that a third survey will be carried out during 2002 to highlight the predicted increase in species diversity over the past four years.
