Program looks at ways in which islands are formed and how they are colonised by plants and animals. In particular the importance of islands as breeding sites for turtles, and the problems associated with introduced animals.
Arid inland ecosystems are investigated in this program. Topics covered include the poor, ancient soils and the fallacy of vastness which often renders the ecosystem useless, day/night cycle, seasonal variations & the effect of introduced species.
With the use of computer graphics,. This program introduces students to the concept of an ecosystem. Several ecosystems are briefly explained and illustrated, and examples are given of human involvement in these systems
The dry sclerophyll forest is the most characteristic Australian vegetation, although it is less valued than other ecosystems. This program examines the unique flora and fauna of this ecosystem, and focuses on the koala. Also shown is the effect humans.
Why are urban settlements in particular locations? This program addresses this question and looks at the inputs and outputs of an urban ecosystem and the matter and energy flows. Students are shown how the ecosystem is totally artificial.
In studying this ecosystem the program investigates the whole catchment approach, problems arising downstream, the valuable corridors of remnant vegetation and movement of wildlife. Seasonal changes are also considered together with human impact on waste.
