Site 43 Bullock Creek

Description
The Bullock Creek sites includes freehold agricultural land, unused road reserve and water frontage.

Vegetation Description and Composition
The timbered areas are described as Open Woodland dominated by Eucalyptus largiflorens (Black Box). The understorey predominantly consists of Muehlenbeckia florulenta (Tangled Lignum), native and introduced grasses, Lolium spp. (Rye-grass - currently no longer present), and Critesion marinum (Sea Barley Grass). Members of the Chenopodiaceae Family present include Atriplex semibaccata (Berry Saltbush), Sclerolaena muricata (Five-spined Bassia) and Maireana decalvans (Common Bluebush). Greater than 50% of species present were introduced species and their abundance has not changed greatly over the past five years. However, current dry seasonal conditions have reduced the total number of species by 50%, and now introduced species make up fewer than 20% of total species, and their level of abundance is greatly reduced. There are three salt indicator species present. Tree health appears in slight decline and the general appearance of the trees is one of being under continued stress. Tree regeneration is minimal due to loss of seedlings through grazing by cattle, rabbits and hares. There has been considerable change in vegetation survey results when compared with previous vegetation data; with total number of species present having halved due to the continued dry seasonal conditions.

The adjacent land uses include cropping and cattle grazing.
