Biodiversity: What is it and why is it important

What is it?

Biodiversity (Biological diversity) means “the variety of all life forms”.

Biodiversity refers to the variety of living organisms associated with land and water - the different plants, animals and micro-organisms, the genetic information they contain, and the ecosystems they form.

Why is it important?

Biodiversity underpins the processes that make life possible. An intact biodiversity is critical to the functional integrity of all ecosystems ( Roth et al. 2002 ). Healthy ecosystems are necessary for maintaining and regulating atmospheric quality, climate, fresh water, marine productivity, soil formation, cycling of nutrients and waste disposal. For these functions, redundancy is required in system components for system resilience.

Biodiversity also supports economic activities, with Australian plants and animals attracting tourists and providing food, medicines, energy and building materials. Our biodiversity is a reservoir of resources that remains relatively untapped.

Biodiversity has spiritual and recreational significance for most people and is central to the cultures of Aboriginal people. [see the Caring for Country Plan ]. For more information on biodiversity and its values and services, click here .

Biodiversity is of great value within the Burdekin Dry Tropics region, although its values and services also extend well beyond the regional boundary to include national and international benefits. For more information, see Biodiversity in the BDT Region .

BDTNRM Plan

As described more fully in the Burdekin Dry Tropics Natural Resource Management Plan 2005-2010 , the BDTNRM’s targets and management actions for conserving biodiversity falls into 4 broad themes, under the umbrella of the Biodiversity Programme. Biodiversity conservation also overlaps with other asset Programmes including Surface Water and Wetland, Coats and Marine, and Land Soils and Agriculture.

Assistance sought for the Australian National Waterhole Count

 In recent years counting finches coming in to waterholes to drink in the early hours of the morning has been highly successful, and is a valuable tool in the conservation of some of our most threatened species.  Birds such as the Gouldian Finch move vast distances each day and very often the only time to sight (and particularly count) them is when they are drinking. This behaviour is typical of many other species, particularly in the drier parts of the Australian continent.

 As a way of using this behaviour to our advantage, this year will see the very first Australia wide “National Waterhole Count”. All you need are a pair of binoculars, a place where birds come to drink, and to be available count on morning of the 11th October 2008.  It doesn’t matter if you count at the leaky tap in your backyard or a water trough on the Canning Stock Route - the important thing will be to count!  We are hoping to have as many volunteers as possible, and all data will be deposited with Birds Australia as part of the national Altas of Australian Birds database. The method is simple and a survey pack, complete with data sheets and a description of the methods, is available by contacting count coordinator Milton Lewis via email at: dalysium@iinet.net.au

 Annual Black Throated Finch (BTF) Waterhole Count

The BFT Recovery Team conduct a water hole count every year - set for the weekend of 18 & 19 October 2008. The obsevers must be in position by 0600hrs on Saturday and Sunday mornings.  If anyone wants to volunteer please contact Rosemary Payet - BTF Recovery Team Secretary by email at rosemaryp@westnet.com.au

Landcare has many volunteer working groups along the Ross River. Volunteers in the community are trying to make a difference to our local environment and major waterways by re-establishing native vegetation and creating healthy ecosystems.

If you are interested in joining any of the Coastal Dry Tropics and Landcare Inc volunteer groups, download the information sheets for the Bush Garden , Lou Lister Park and Upper Ross Landcare working groups. To find out more information for your area contact Leigh O'Neil on 4721 4322/0428 428 542 or email landcare@bigpond.net.au So come down and have a great time for just a couple hours a month. Do as much or as little as you like: learning, helping and having fun!
