Title	Byron Bay Graminoid Dry Clay Heath Endangered Ecological Community (EEC) 2007. VIS_ID 77
Alternative title(s)	ByronBayDryClayEEC_2007_E_77
Abstract	Byron Bay Dry Graminoid Clay Heath (BBDGCH) Endangered Ecological Community (EEC) mapping by Andy Baker. Also known as Clay Heath or Graminoid Clay Heath or Byron Bay Clay Heath. This is the updated layer generated as part of the Cape Byron and Arakwal veg mapping project, reports dated March 2009 and September, 2010. A vegetation survey, classification and mapping program of Cape Byron State Conservation Area and Arakwal National Park was carried out during 2007-8. The main aims of the study were to identify, classify and map all extant vegetation within the study area, identify vegetation and flora of conservation significance, and also identify any processes currently threatening the vegetation. All vegetation was surveyed and mapped via API, exhaustive ground truthing and data analysis. Actual presence of Byron Bay Dry Graminoid Clay Heath mapped – as either dominant or low strata. Pure EEC is mapped by selecting “Clay Heath” in the Label field. This is what is mapped as Clay Heath in the Arakwal veg map. The other categories are broadly known as Clay Heath. VIS_ID 77

Lineage	Targeted sampling was undertaken using 62 survey plots each of 0.04ha. Examination of floristic relationships and refinement of the final classification was undertaken using the PATN hierarchical clustering program. Floristic Assessment of Byron Bay Dry Graminoid Clay Heath: Although analysis of the data was not undertaken, the association appears to be of a different floristic composition than that originally described by other authors and myself. The association was described in the nomination as Banksia oblongifolia - Allocasuarina littoralis - Themeda australis - Schoenus brevifolius. A quick scan of this data suggests the (co-)dominance of Hibbertia vestita, and the proportionately high abundance of Patersonia sericea and Pultanaea villosa. Aristida warburgii is quite common, however, at this stage of community development it appears not to be co-dominant. Additionally, Allocasuarina littoralis was relatively underrepresented. I’ve included some additional points below that I felt needed highlighting. Statement of Survey Adequacy: The sampling appears to be sufficiently representative. The survey sites were chosen so as to sample the range of variation across the community and included sites across aspect and altitudinal ranges. A high percentage (61%) of species previously recorded were again recorded during this survey (80% when including opportunistic records). The number of species recorded per site ranged between 23 and 39. Additional species recorded for the community through plot sampling total 24. Each site (10 x 10m) was subject to about 1 hour of sampling effort. Pure EEC is mapped by applying the following filter to the Label field: Label = “Clay Heath”
