    Australian Plants Suitable for Tamworth Regional Council Areas Eucalyptus blakelyi Photo Tony Croft Tamworth Group of Australian Plants Society As at July 2007 Eucalyptus blakelyi II TAMWORTH REGIONAL COUNCIL RAINFALL DATA Most of the Tamworth Regional Council area receives an average annual rainfall of 600 to 800mm except for the north- west corner on the Mount Kaputar plateau and the tablelands country from Bendemeer through Woolbrook to Hanging Rock above Nundle which often receives between 800 to 1000mm. Similarly temperatures vary across the region with average annual minimums on the tablelands and nearby areas between 6 and 9 degrees Celsius. A series of frosts are received across the entire region each winter. Average annual maximums are between 18 and 21 degrees on the tablelands, 21 to 24 degrees across most of the region and 24 to 27 degrees in the west of the region. 1. Barraba 2.

  • Rangelands, Western Australia
    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.

    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.

The northern boundary abuts the Anangu Pitjantjaraku Lands (Pitjanttjara Aboriginal Lands) and the southern boundary is the northern dog fence boundary of Commonwealth Hill pastoral lease. The total area of the Tallaringa study area is almost 12 000 km2.and it is divided into two almost equal sized blocks.
