}" of Wang~nu and Scarp land systems. The community, as I' it o,ccurs on the Wanga;l u mudstone (Wangal uland sys tem), differs slightly from that occurring on the main plateau surface in. th~t it contains. species such as Euca7 yt/pus jensenii, E. setosa and E. porrecta in the '"j - .. secondary tree layer. This assemblaQe can be regarded as having a high conservation value. Like the previous community this one may al so be regarded as 'typical' of the eucal ypt forests and woodlands of Cobourg Pen~nsula and as such rates highly for representativeness. The community also contains such species as oGossypium cunninghamii, 1 isted as rar,e by Leigh et a7. (1981) and endemic tc? the Peninsula, and Hovea 7ongifo7ia var, pannosa which, although quite common on the Poeninsula, is found only here and in the Murgenella area. ~10nsoon Forest. (Ma,p Un it 6 - 42.8 km 2) Thi s commun ity, a Mid-high ,Closed Forest in the Walker and Hopkins classification, is commonly referred to by a variety of names: Monsoon Forest" Dry or Wet Monsoon Forest, Deciduous Monsoon For~st, Rainforest and Vine Thicket being the most common. The most apt name for such communities on Cobourg Peninsula is Mon soon Forest si,nceotohey lack epiphytes and lianas and are not 'wet', i.e. the product of high year-round rainfall or of v~ry sheltered habitats such as east coast rainforests. Two more or less distinct types occur in the area: that which occurs on the 1 ateri zed bauxitic material with shallow gravelly red earth soils (the most common form) and that which occurs behind the beach systems where the substrate is cal careous sand and the water table is close to the surface for much of the year. No distinction has been made between these two types for the p~rposes of mapping and report writ ing in this instance. These monsoon forests are the characteristic fea ture of oKennedy land system to which they are wholly confined. They are formed by a dense to very dense - 33
