Vegetation at Wybung and Wamberal Heads was also mapped in the same study. Vegetation maps were constructed with the assistance of aerial photographs. At Norah Head, 12 vegetation types were recognized on structural grounds (Specht 1981). Closed-forest and low closed-forest (some of which were remnant littoral rainforest), Eucalyptus botryoides forest, Banksia integrifolia open-woodland with a bitou bush understorey, coastal scrub/heath and bitou bush closed-heath were the major vegetation types. At Wybung Head, 7 vegetation types were recognized, with various types of scrub/heath and a Themeda grassland being found. At Wamberal Head, 5 vegetation types were recognized, with B. integrifolia open-forest with bitou bush understorey, scrub/heath and some Themeda grassland being found. Species list were compiled for each vegetation type; exotic species were common in occurrence, and dominated some vegetation units in terms of biomass. Two species of conservation importance in the area were found: Rhyodomyrtus psidioides and Botrychium australe, both near Jenny Dixon at Norah Head.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115355717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sea Level Change and Greehouse: Implications for Wetlands 海平面变化和温室:对湿地的影响

{"title":"Sea Level Change and Greehouse: Implications for Wetlands","authors":"E. Bryant","doi":"10.31646/WA.130","DOIUrl":"https://doi.org/10.31646/WA.130","url":null,"abstract":"In 1985, the Conference on Greenhouse Warming held at Villach, Austria, predicted a rise in sea level by 2030 AD of between 0.2 and 1.4m caused by melting of ice-caps (including mountain glaciers) and thermal expansion of the oceans (World Meteorological Organisation 1986). Recent research, however, suggests that thermal expansion of water in the upper 100-200m of the oceans is the most likely major cause of future sea level rise. Predictions about the extent of this rise have been revised downward because it is now realized that warming of air around the Antarctic ice-cap will lead to increased snowfall, thus counteracting the effect of thermal expansion. What has not been widely recognized is the fact that sea level behavior from year to year and over the long term, especially in Australia, is climactically controlled, with complex feedback mechanisms operating on regional scales (Bryant 1988a, Bryant et al. 1988). The short term variability in sea level behavior may be 1-2 orders of magnitude greater than the average trends defined from many sea level records. \u0000 \u0000In this paper the nature and variability of sea level changes within Australia will be discussed first. Secondly, the impact of this variability upon Greenhouse predictions of sea level rise and some more current predictions for sea level elevations in the next 40 years will be presented. Finally, planning options necessary to minimize the effect of rising sea level upon wetlands will be reviewed.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128260315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conservation value has been recognised by the National Trust, have been set aside as Bicentennial Park, following a Macquarie University study (Anon. 1978). Substantial estuarine wetlands are conserved within this Park though important remnants of the natural vegetation remain unprotected outside this area. This paper described the remaining mangrove, saltmarsh, swamp oak and eucalypt forests of the Bay and the changes they have undergone since European settlement. \u0000 \u0000Homebush Bay is about 12 km west of Sydney on the southern side of Parramatta River and near the geographical centre of Sydney’s metropolitan area (figure 1). Two major creeks drain into it, Haslams Creek from the south-west and Powells Creek from the south. Quaternary alluvial sandy clays cover most of the low lying lands and the river valleys. On higher ground is Wianamatta Shale which weathers to form deep clay soils. The climate and other physical features are described in the Macquarie University report (Anon. 1978), and aspects of the intertidal fauna are discussed in Robinson et al. (1983) and Jones and Frances (this volume).","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124371087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such sites may then be covered with topsoil and/or planted with target saltmarsh plant species. However, few such projects in saltmarsh establishment are designed in a way and/or monitored in a manner that would allow for the collection of data that may assess efficacy to guide future restoration projects. A small saltmarsh restoration project in Lake Macquarie, New South Wales, incorporated an experimental design that sought to address the questions as to whether topsoil addition and planting are necessary for the effective establishment of saltmarsh vegetation. Two years post saltmarsh establishment, topsoil addition facilitated the growth (in terms of percentage cover) and recruitment of Sarcocornia quinqueflora, though topsoil provided no appreciable benefit for Sporobolus virginicus. It was further shown that while planting assisted growth for Sarcocornia quinqueflora, it was a necessity for the establishment of Sporobolus virginicus within such time frames. Importantly, this study demonstrated the value of incorporating into a wetland restoration projection an experimental design that tests specific hypotheses.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121234160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
