  • Jervis Bay Territory Page 1 of 50 21-Jan-11 Species List for NRM Region (Blank), Jervis Bay Territory
    Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect.

  • Post-Fire Recovery of Woody Plants in the New England Tableland Bioregion
    Post-fire recovery of woody plants in the New England Tableland Bioregion Peter J. ClarkeA, Kirsten J. E. Knox, Monica L. Campbell and Lachlan M. Copeland Botany, School of Environmental and Rural Sciences, University of New England, Armidale, NSW 2351, AUSTRALIA. ACorresponding author; email: [email protected] Abstract: The resprouting response of plant species to fire is a key life history trait that has profound effects on post-fire population dynamics and community composition. This study documents the post-fire response (resprouting and maturation times) of woody species in six contrasting formations in the New England Tableland Bioregion of eastern Australia. Rainforest had the highest proportion of resprouting woody taxa and rocky outcrops had the lowest. Surprisingly, no significant difference in the median maturation length was found among habitats, but the communities varied in the range of maturation times. Within these communities, seedlings of species killed by fire, mature faster than seedlings of species that resprout. The slowest maturing species were those that have canopy held seed banks and were killed by fire, and these were used as indicator species to examine fire immaturity risk. Finally, we examine whether current fire management immaturity thresholds appear to be appropriate for these communities and find they need to be amended. Cunninghamia (2009) 11(2): 221–239 Introduction Maturation times of new recruits for those plants killed by fire is also a critical biological variable in the context of fire Fire is a pervasive ecological factor that influences the regimes because this time sets the lower limit for fire intervals evolution, distribution and abundance of woody plants that can cause local population decline or extirpation (Keith (Whelan 1995; Bond & van Wilgen 1996; Bradstock et al.

    Vegetation of Imbota and Yina Nature Reserves, Armidale, New South Wales John T. Hunter School of Behavioural, Cognative and Social Sciences, University of New England, Armidale, NSW 2351 AUSTRALIA Email: [email protected] Abstract: The vegetation of Imbota Nature Reserve (30° 35’S, 151° 45’E) (218 ha in area), 10 km south-east of Armidale, and Yina Nature Reserve (30° 29’S, 151° 45’E), (101 ha in area), 10 km east of Armidale, on the Northern Tablelands, NSW, is described. Based on classification analyses, air photo interpretation and ground-truthing, seven vegetation communities are described and mapped : 1. Eucalyptus caliginosa (Broad-leaved Stringybark) Grassy Forest and Woodland on deep soils at Imbota 2. Eucalyptus viminalis (Manna Gum) Grassy Forest and Woodland, Community 3. Eucalyptus caliginosa (Broad-leaved Stringybark) Grassy Forest and Woodland on shallow soils at Imbota 4. Eucalyptus caliginosa (Broad-leaved Stringybark) Grassy Forest and Woodland at Yina 5. Eucalyptus blakelyi (Blakely’s Red Gum) – Eucalyptus melliodora (Yellow Box) Woodland 6. Eucalyptus viminalis (Manna Gum) – Eucalyptus nova-anglica (New England Peppermint) Grassy Forest and Woodland 7. Riparian Herbfields 252 vascular plant taxa (from 59 families) were recorded from the two reserves, 179 species in Imbota NR, the larger reserve and 209 in Yina NR. The lower species richness at Imbota is likely to have resulted human disturbance rather than from overall habitat heterogeneity. Cunninghamia (2007) 10(2): 215–224 Introduction 1030 m. The eastern boundary is marked by Burying Ground Creek, a minor tributary of the Commissioners Waters, Imbota Nature Reserve (30° 35’S, 151° 45’E) and Yina that eventually flows into the Gara River and the eastern Nature Reserve (30° 29’S, 151° 45E’) lie 10 km to the fall of the Divide.

    Biodiversity Summary for NRM Regions Guide to Users Background What is the summary for and where does it come from? This summary has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. It highlights important elements of the biodiversity of the region in two ways: • Listing species which may be significant for management because they are found only in the region, mainly in the region, or they have a conservation status such as endangered or vulnerable. • Comparing the region to other parts of Australia in terms of the composition and distribution of its species, to suggest components of its biodiversity which may be nationally significant. The summary was produced using the Australian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. The list of families covered in ANHAT is shown in Appendix 1.
