5. THE VEGETATION COMMUNITIES OF COBOURG PENINSULA 5.1 Introduction: Al tho ugh Cobourg Pen insul a has been, the. subj ect of many botan ical collecting expeditions in the past, only one attempt has been made to date to describe and map the vegetation communities occurring there. Chippendale (1974) published a v,eget,ation map of the Penin sula (at a scale of approximately 1:1,150,000) with accompanying notes and com~unity descript~ons. _ At this scale of mapping the com munities were, of necessity, very broad and ther,efore of somewhat 1 imited use in developing manageme~t options for, and gauging the conservation values of the Peninsula. In this pr9jec! the vegetation communities have been mapped at a scale of ;1:100,000. Twelve (12) major community types have been recognised, as wel,l as several minor communities which are not map able at this scale. 5.2 Sampling Considerations and Classification: stereo aerial photography at a scale of approximately 1:85,000 was interpreted spe~ifically for vegetation patterns prior to commen cement of fieldwork. Field sites were chosen so that the full range of communitoies could be sampled with some repl ication in the main c omm un it i e s . At each formal. site, centered on the augered ,soil profile and taking approximately a 30 meter radius around it, the vegetatio~ community was described in terms of both structure and floristics. Floristic data were collected for all strata in the form of presenc /absence of seec ies together wi,th a relative abundance rating. Structural data, including heights, crown cover and height variation, were recorded for the upper and lowest strat? whil st heights only were recorded for other layers in the community. The termi~ology and classification system is that of Walker and Hopkins (1984). This system has the ability to utilize both, struct ural and floristic data in the final community classification. 5.3 Vegetation Communities: Sites from this survey were first grouped according to the structure of the dominant (tallest) stratum with these major group - 30
