“…Determining the species likely to be represented in a modern or fossil pollen study will also be assisted by a regional vegetation survey, e.g. an investigation of rainforest history and dynamics in the Robertson area (Kodela 1990a(Kodela , b, 1996. These types of study benefit from establishing reference pollen sets to compare morphologies.…”

Pollen morphological descriptions and photographic illustrations based on light microscope analyses are provided for over 60 angiosperm taxa that occur in rainforest and wet sclerophyll forest communities in the Illawarra region of New South Wales. The resulting pollen taxonomy contributes to the study of Holocene mesotherm rainforest floras in coastal and tableland New South Wales and, because many species are or will have been shared with other vegetation types in the past, also to the floras of other botanical regions. Taxonomic relationships assessed on pollen morphology are discussed for several taxa.

“…In order to reconstruct changes in regional vegetation patterns and to allow comparison with similar studies elsewhere in Australia, the pollen sum used in this study consists of pollen taxa known to have region-wide dispersal; that is, all dryland types with the exception of those taxa such as Melaleuca, Acacia, Leptospermum, Chenopodiaceae and ground ferns, whose pollen is only locally dispersed (Dodson, 1977b(Dodson, , 1983Macphail, 1979;Kodela, 1990aKodela, , 1990bKodela, , 1996Kershaw et al, 1994).…”

We present a reconstruction of the vegetation history of the last glacial-interglacial cycle (ca. 75 k cal. yr BP-present) at Redhead Lagoon, an enclosed lake basin in coastal, eastern New South Wales, Australia. The sequence of vegetation change at the site is broadly comparable with the pattern of climatically induced changes observed in many other pollen records in southeast Australia. Open woodland-herbland and woodland-forest communities correspond with glacial and interglacial periods respectively, with an additional change towards a more open understorey vegetation assemblage over the last 40 000 yr. The driest conditions appear to have occurred during the height of the last glacial (some time between 30 and 20 k cal. yr BP). This is consistent with other records from southeast Australia, and provides support for a poleward shift in the subtropical anticyclone belt and, less certainly, for the thesis that the Southern Hemisphere westerlies intensified during this period. In marked contrast to most sites in southeast Australia, Casuarinaceae dominates the pollen record through the height of the last glacial period and into the Holocene. The postglacial climatic amelioration is accompanied by the general reappearance of tree pollen in the record, by the disappearance of several open and disturbed environment indicator taxa, by increases in organic sediment deposition and pollen taxon diversity, and by higher water balances. While climate appears to have been the major control on patterns of vegetation change at this site throughout most of the last glacial-interglacial cycle, changes in depositional environment and hydrology have also played a role. Significantly, substantial increases in the rate and magnitude of many indicators of environmental disturbance since European settlement suggest that humans are now the most important mechanism for environmental change.

“…Most Australian rainforest taxa except conifers are insect or bird pollinated and their representation can be low even at sites where rainforests dominate (Kershaw and Strickland, ; Kodela, ,), but there are exceptions. We highlight two taxa found in the Little Llangothlin record, Myrsine ( Rapanea ) and Macaranga (Fig.…”

This paper presents the results of a palynological investigation into the late Last Glacial Maximum (LGM) and last deglaciation (ca. 20 000–9000 cal a BP) from Little Llangothlin Lagoon, in the sub‐tropics of eastern Australia. The Lagoon held permanent water during the late LGM and early deglaciation but was intermittently dry during the late deglaciation. During the late LGM, local vegetation was dominated by a sub‐alpine herbfield but the significant presence of rainforest taxa in the pollen record indicates the survival of rainforest, rainforest margin or wet sclerophyll communities close to the site. By ca. 17 000 cal a BP, open Eucalyptus forest replaced the alpine herbfield vegetation indicating that warming had commenced. Rainforest taxa disappeared at this time but re‐appeared at the end of the deglaciation. The LGM conditions are consistent with a dominant circulation system whereby persistent high pressure over eastern Australia brings onshore easterlies to this region and maintains humid conditions along the east coast and highlands of the Great Dividing Range. This is similar to modern winter circulation but the persistence of rainforest and wet sclerophyll taxa suggests an increase in easterly flow over modern conditions during the LGM.
