GEOS – Australian Climate and Vegetation explores contemporary climatic patterns and controls in Australia, development of the. Today, the identity of all Australians is shaped by a relationship with the natural its soils and seas are among the most nutrient poor and unproductive in the world . Australian soils are highly dependent upon vegetation cover to generate. Relationships between climate, productivity and vegetation in southern NDVI data to assess herbage production in the arid rangelands of central Australia.
Precipitation patterns across Australia are seasonal in nature. In northern Australia, rain falls in the summer months, while the winter months are dry.
Due to this region's closeness to the equator, the temperature remains constant year-round. In eastern Australia, rain also falls mostly during the summer. Since this part of Australia is further from the equator, summer months are warmer than winter months. In the southern part of Australia, rain usually falls in the winter.
In eastern and central Australia, little rain falls at all. See Image 2 Temperature Temperature patterns in Australia change depending on the latitude.Describe THE NATURAL VEGETATION OF AUSTRALIA/Vegetation of the S-E and S-W coasts if Australia. G-6
Latitude is a distance north or south of the equator. In areas closer to the equator, warmer temperatures are experienced year-round. As you move further south into higher latitudes, the overall temperatures become cooler, while the seasonal variation difference between temperatures in summer and winter months increases.

Some authors describe linear relationships, while others found hump-shaped patterns, especially where the assessed productivity gradients were long Garcia et al. Large-scale analyses often suffer from a lack of sufficient numbers of comparable samples. Large vegetation databases offer increasingly popular data sources Tichy,although assessments of species richness based on traditional vegetation samples may be somewhat biased Chytry, Unfortunately, most of the available large datasets cover the comparatively well-studied regions of moist western Eurasia.
For central Eurasia, Russian and Mongolian botanists have also collected large numbers of vegetation samples, but no formal statistical evaluation has been conducted as yet.

To our knowledge, no publication addresses the relationship between local plant community composition and productivity in the region, which seems surprising because Central Asian drylands are expected to exhibit close climatic controls Christensen,Christensen et al. We aimed at closing this gap by conducting an analysis of a large set of vegetation samples collected in the Gobi of southern Mongolia between and Even where other data on plant communities are available, lack of data on productivity or similar proxies often renders formal correlation analysis difficult.
Precipitation is the main driver of productivity within arid environments Ludwig,and thus species richness is expected to correlate with precipitation. An open-source climatic extrapolation model has recently become available offering averaged data on a suitable spatial scale Hijmans et al.
Precipitation data can be used to estimate productivity in drylands Le Houerou,Huxman et al. Climate, types of soil and landforms affect an area's vegetation. This chapter looks at the different types of vegetation zones of Australia and the main factors affecting them.

Vegetation types Australia's flora can be divided into different vegetation groups. The most important factors that determine an area's vegetation are rainfall and temperature. Most plants in Australia are well adapted to the arid dry conditions of the continent.
The main vegetation type in Australia is the hummock grasslands. Grassland is a grass-dominated area where few or no trees grow. Hummock means a small natural hill.
Hummock grasslands make up about one-quarter of the native vegetation.

The main plant species of the hummock grasslands are different clump-forming grasses with pointed leaves. Eucalypt woodland is an open forest, also known as dry sclerophyll forest or more simply 'the bush'. Tough leaves and woody fruit covers are typical features of dry eucalypt woodland plants. Plants of eucalypt woodland are well adapted to coping with fire. The most common species is Eucalyptus camaldulensis which grows along the majority of inland waterways and creeks in Australia.
