The interpretation of traces
(2004)
This paper argues that parts of the lexical content of an A-bar moved phrase must be interpreted in the base position of movement. The argument is based on a study of deletion of a phrase that contains the base position of movement. I show that deletion licensing is sensitive to the content of the moved phrase. In this way, I corroborate and extend conclusions based on Condition C reconstruction by N. Chomsky and D. Fox. My result provides semantic evidence for the existence of traces and gives semantic content to the A/A-bar distinction.
After this issue you will have a new editor at the helm: Dr Volker Framenau. As you have been reading in the newsletters Volker has a background in both taxonomy and ecology. A network across both disciplines should help keep us well informed of the latest news and research within the region. Volker is very enthusiastic about the society and I encourage members to keep supporting the newsletter by sending him your articles. Volker has been helping me develop the webpage so that will continue to evolve.
The fires of January 2003 burnt much of the treeless high mountain country of Victoria, New South Wales and the Australian Capital Territory, and were the first extensive conflagration of this area since 1939. For this reason there are remarkably few studies of the response of alpine plants and vegetation to fire. A flora survey of treeless subalpine vegetation in the Kosciuszko area in late 2002 sampled 215 sites. Of the 119 sites that were burnt, 60 were relocated and re-sampled in late 2003 to assess the mode and extent of regeneration in a range of treeless plant communities. Twenty-four species (including 3 exotics) were recorded only in the pre-fire sampling. Fifty species (including 18 exotics) were recorded only in the post-fire sampling. One species, Chenopodium erosum, had not previously been recorded in Kosciuszko National Park, and is believed to be the first native chenopod recorded in alpine vegetation in Australia. There was no significant difference in mean number of species per quadrat between pre-fire and post-fire quadrats. The average number of weeds per quadrat was, however, significantly greater post-fire. Most of this difference was attributable to the significantly greater number of weeds per quadrat in bog vegetation after the fire. Of the 290 species recorded, 111 species regenerated from seed, 197 species regenerated from resprouting organs (roots, tubers and/or basal stems) and 49 species regenerated from both seed and resprouts. Based on the regeneration observed, most plant communities will return naturally to their pre-fire species composition and cover over a period between a few years and a few decades. Major exceptions will be those communities where the ‘keystone’ species appear to have been lost at least at a local scale. Principal amongst these are bog communities that incorporated significant biomass of Sphagnum cristatum pre-fire, Podocarpus lawrencei shrublands and Celmisia costiniana closed herbfields. Consideration might be given to augmenting their recovery. It will be important to exclude fire from these communities until their recovery is complete.
Floristic communities from the alluvial floodplains and near-alluvial plains of the lower Dawson River, mideastern Queensland, are described from near-intact sites. Three broad and ten detailed floristic groups were defined. Differences in community composition appeared related to soil type, localised disturbance and latitude. Weeds comprised a small proportion of the total flora, although they presently dominate some areas. Grasses were the main exotic species present, and appeared to have increased within the last forty years.
Bryophyte composition in a native grassland community subjected to different long-term fire regimes
(2004)
The vascular species composition of volcanic plains grassland remnants of western Victoria is strongly tied to management history, with frequently burned remnants often supporting the most diverse native flora relative to grazed and long-unburned remnants. How the fire regime affects the composition of the bryophytic mat, however, has not been documented. I surveyed the moss and liverwort flora of six Themeda triandra grasslands subjected to different long-term fire regimes to understand how fire might affect mat composition. A total of 27 non-vascular species (19 mosses and 8 liverworts) were recorded, of which nine species were recorded only from a single location. Non-vascular species contributed 28% of the total diversity observed in this study. The liverwort Lethocolea pansa was the most obvious species at all sites, while the mosses Rosulabryum billardieri and Fossombronia intestinalis were also found at all sites and hence, would appear to be robust to fire at different frequencies. Frequently-burned (1–2 yr interval) grasslands generally had lower mat species richness than longer-unburned sites (4 to >20 yr intervals) and appear to support a subset of the flora (due to the loss of moss species) rather than a distinctly different flora. The preliminary results of this study contrast with the evidence usually found for vascular species, i.e. that frequent fire favours greater native species richness. Hence, the two components of the flora would appear to respond in different ways to fire and this should be considered in the conservation planning for this grassland community. Further field sampling is warranted to confirm the initial trends identified by this study.
The vegetation of Basket Swamp National Park (2820 ha), 30 km north east of Tenterfield (28°54’S, 152°09’E) in the Tenterfield Shire, in the Northern Tablelands Bioregion NSW, is described. Seven vegetation communities are mapped based on survey of plots, subsequent ground-truthing, air photo interpretation and substrate.
Communities described are: (1) Eucalyptus campanulata (Blackbutt) – Eucalyptus cameronii (Diehard Stringybark) Open Forests, (2) Eucalyptus campanulata (Blackbutt) – Eucalyptus cameronii (Diehard Stringybark) Grassy Open Forests, (3) Leptospermum trinervium (Tea-tree) – Leptospermum polygalifolium subsp. transmontanum (Creek Tea-tree) Riparian Scrub, (4) Leptospermum trinervium (Tea-tree) – Kunzea obovata (Pink Kunzea) – Leptospermum novae-angliae (New England Tea-tree) Heaths & Shrublands, (5) Ceratopetalum apetalum (Coachwood) – Lophostemon confertus (Brush Box) Closed Forest, (6) Eucalyptus obliqua (Messmate) – Eucalyptus campanulata (Blackbutt) Tall Open Forests, and (7) Baeckea omissa (Baeckea) – Baloskion stenocoleum (Sedge) Heathy Sedgelands.
All but two communities (3 & 7) were considered adequately reserved locally, no listed endangered or vulnerable communities were found. Thirty-six taxa were considered to be of conservation significance of which two are listed as vulnerable on Schedule 2 of the NSW TSC Act.A further nine have been reported under the RoTAP criteria.
Pultenaea glabra Benth. is a recently revised taxon which includes disjunct populations in Victoria, NSW, and Queensland. Victorian populations were previously described as Pultenaea weindorferi Reader, and listed as rare in Victoria. Pultenaea glabra is known from four locations in Victoria; it is locally abundant at the Bunyip and Lerderderg-Wombat localities, is uncommon at Wandin, and is in serious decline at Kinglake. Viable soil-stored seeds were present at all sampled locations, and seed germination was enhanced by heat pre-treatments, though germination of untreated seeds also occurred. Few mature plants remain at Kinglake and the population structure differed markedly from the other sampled populations. It has been suggested that the species requires a specific fire regime for regeneration, but it is likely that the severe decline in the Kinglake population is the result of grazing, rather than an inappropriate fire regime. At this site, germination is occurring but plants have not reached maturity, and the species is represented by only seedlings. Managing the species at Kinglake will require consideration of multiple factors, and reintroducing fire to the site at this stage may jeopardize seedling survival and result in local extinction.
Twenty-one riparian vascular plant communities are defined, mapped and described using presence/absence data from 460 sites from relatively unmodified stretches of rivers and streams on mainland Tasmania. The process of classification involved selection of groups of floristically distinct sites from a sorted table produced by a polythetic divisive process. The communities have strong geographic patterns. Many communities have a wide range of structural expression and/or dominants. Nearly half of the native vascular flora of Tasmania is present in the sites, including a large number of conservation-significant species, some of which are concentrated in riparian vegetation. In the drier, lowland parts of the State there are large areas with little or no native riparian vegetation remaining. Several of the communities that occur in this environment appear to be totally unreserved, while most of the communities from colder and more humid areas are represented within secure reserves.
An improved approach to predicting preferred habitat and targetting survey effort for threatened plant species is needed to aid discovery and conservation of new populations. This study employs several approaches to aid in the delineation of preferred habitat for the Leafless Tongue Orchid, Cryptostylis hunteriana Nicholls. BIOCLIM, a bioclimatic analysis and prediction system, is used initially to generate a bioclimatic habitat envelope within which the species can be expected to occur, based on all known sites in the Shoalhaven Local Government Area. Within the BIOCLIM envelope it is possible to further investigate the extent to which the species exhibits preferences for other habitat factors such as geology, soil landscapes and forest ecosystems. Multivariate techniques are used to compare floristic data from sites where Cryptostylis hunteriana is present, and sites from forest ecosystems where it has not been recorded historically. These techniques are also used to identify species which are diagnostic of each of these sets of sites. All 25 sites with Cryptostylis hunteriana populations are restricted to six forest ecosystems having a total area of 15% of the Shoalhaven Local Government Area and 47% of the BIOCLIM envelope. Within these forest ecosystems, ten plant species deemed indicative of the possible presence of the Cryptostylis hunteriana are identified.
