Bottle Composting. Bottle Composting Teaching Objectives Beginning concepts Living organisms produce organic matter. Compost consists of decayed organic matter. Just as there is a cycle of life, there is a cycle of decomposition in which once living materials break down and release their nutrients to again support life. Many synthetic materials created by humans do not decompose. Advanced concepts Humus is a dark, crumbly material resulting from the decomposition of organisms and parts of organisms, and becomes part of the soil. Time Required for Exercise Stage 1: Construct the bottle columns-2 to 3 hours Stage 2: Fill the compost columns-1 hour Stage 3: Composting-Observation over several months Materials Needed This exercise requires the following: Exploratory Questions Ask your students questions and discuss ideas they might have such as: What would happen if plants and animals (organisms) that die did not decay?

Wildlife of Tasmania Tasmania has a remarkably intact fauna and acts as a refuge for many species that have been lost on mainland Australia. See our comprehensive account of the unique fauna of Tasmania. Plants The diversity of Tasmania's vegetation is remarkable, and includes some of the most ancient plant species on Earth, the tallest flowering trees, the oldest plant clones and a high proportion of endemic species. Fire Ecology Fire plays a significant and complex role in the ecology of Tasmania's vegetation communities. Geoheritage Discover the geomorphological processes that shaped the beauty of Tasmania, the island's rich biogeographic heritage and its Gondwanan legacy. Conservation Tasmania's natural heritage faces threats from a variety of factors.

Protected Matters Search Tool - EPBC Act - Home Page. This is the new Protected Matter Search Tool, redeveloped as of December 2010. In addition to a more streamlined map interface, the tool offers new map layers such as the Great Barrier Reef Marine Park, NRM regions and Commonwealth Marine Areas. New data in the report includes nationally important wetlands and you are able to search by Local Government Areas, NRM Regions and Postcode.
Use this search tool to generate a report that will help determine whether matters of national environmental significance or other matters protected by the Environment Protection and Biodiversity Conservation Act 1999 are likely to occur in your area of interest. Any information provided through this facility is indicative only, and local knowledge and information should also be sought where possible.

The Wellington Range provides an outstanding sequence of vegetation types from dry sclerophyll through wet sclerophyll, rainforest and sub-alpine to alpine communities in Tasmania. It supports important representations of a number of wet forest types and an outstanding diversity of dry sclerophyll communities in a relatively limited area.
[Identified in earlier listing] Biogeographic values present in Mount Wellington-Wellington Range are endemic and disjunct flora and primitive and endemic fauna. These are important indicators of past evolutionary and biogeographic processes (Criterion A.1). Tasmania's extreme southerly position and the fact that it is an island means that virtually all Tasmanian species could be interpreted as having biogeographic values. Disjunct flora This place is important as an area which hosts flora populations which have become physically separated from other populations of the same species, resulting in minimal or no gene flow between them.
