Essay on The Mallee Region of Victoria

Within the Murray-Darling Basin, Goulburn Valley is one of the major fruit production regions in Australia (Libby & Dixon 2011). 35% of the fruits and vegetables in Australia are grown in this region due to the fertile soils and ideal climate (Hume Regional Management Forum, Department of Planning and Community Development & Urban Development Division 2010). In addition, the establishment of SPC Ardmona has resulted in the significant growth of economy and employment within the region (Department of Agriculture 2011).

Outline the geographical processes relevant to the management of the Cronulla, Wanda and Kurnell area.

Contain a distinctive top soil that is humose or peaty and a substratum starting at 40cm in depth which has been altered little (Avery, 1980; Buol, 1997). The soils do not contain a disturbed surface layer, the B horizon is not podzolic, weathered or argillic (Avery, 1980; Buol, 1997) and the soil profile is shallow (Ashman & Puri, 2002).

Transects from the third creek catchment (transects 4-6) severely lack in native biodiversity with transect 4 completely arranged with non-native plant life. This could be attributed to the fact that Fourth creek resides within a state conservation park, thus there less influence of human activity on vegetation. This region of the Adelaide hills has been preserved since colonisation however introduced plant species still grow throughout the region. The anthropogenic biome of this catchment enhances the prominence of native species, contrastingly third creek runs throughout rural settlements, including cherry and grape orchards. These factors alongside the plantation of introduced species by white settlers has fostered a reduction in native fauna and thus an increased prominence of European plant life. Native vegetation within this region is mostly restricted to eucalyptus trees. Regarding the structure of diversity within each transect, there is no major difference when comparing the third creek catchment to the fourth creek catchment. Transects 1 and 5 consists of a large variety of plant layers, from large trees to ground cover. Conversely, transect 2 and 6 comprises of mostly lower-ground vegetation with a lack of large bushes or trees. The diversity of vegetation fluctuated throughout each creek, making results in

Dr. Fred Rich presented his research on the presence and creation of sand dunes on the Ohoopee River Preserve from a geological perspective. Dr. Rich is a professor at Georgia Southern University in the department of Geology and Geography. The main purpose of his research was to explain how sand dunes form, where they are located and why they exist. Sand dunes are sand ridges near lakes or deserts that are formed by the wind, aeolian deposition. The presence of a sand dune creates a significant contrast in the deposition of the environment in which one side can be a flourishing environment full of trees or grasses while the other side is just a xeric environment of sand. The preserve itself is a prime example in which the area is surrounded by a cypress forest while the sand dune area inside is just a xeric environment with

However, the Dwight-Irwin soil has more of a deeper, moister quality. Benfield and Dwight-Irwin soils do allow for more species richness than other lower elevated ecosystems but due to the drier soils, Little Bluestem is still the most dominant plant recorded. The dominance of Little Bluestem extends down to the lowest boundaries of the ecosystem, indicating that the soil conditions do stay relatively consistent, despite the change in soil type. This allows “Little Bluestem” to again be the dominant plant species component. The drier qualities of the upper Benfield soil combine with the slightly moister qualities of the lower Dwight-Irwin soil to give the “Dry Mesic” classification. These soil moisture content qualities, the location of this ecosystem along side slopes, and the consistent dominance of the Little Bluestem plant species allows this ecosystem to be classified as Little Bluestem-Dry

The soils of the marshlands here are rich and wet. They were once considered ideal for celery growing, but farming here depended on

Plainsong is unique in the fact that it changes view points in each chapter. Some characters may only get one chapter where others will get multiple chapters; in doing so the author slowly reveals the relationships forming between all the characters. However, none of the relationships have changed as much as the relationship between Victoria and the McPherons.

Heathland is favoured where climatic conditions are typically hard and dry, particularly in summer, and soils acidic, of low fertility, and often sandy and very free-draining; mires do occur where drainage is poor, but are usually only small in extent. Heaths are dominated by low shrubs, 20 centimetres (7.9 in) to 2 metres (7 feet)

Dallas, located in the northeastern part of the state, has a variety of different types of soil. The Gulf Coastal Plain is composed of red and yellow soils, which can be beneficial for the vegetation if proper fertilizer is used (Escape to Texas). Moving more towards central Texas, it has “soils based on weathered decayed limestone” (Escape to Texas). Much of the Dallas area has grassland vegetation, which comes from Mollisol soils, which are rich in calcium and other nutrients (Ritter). The intensely hot summers cause the soil to possess high moisture retention so as not to dry up easily, but when they do become dry, they have a “granular structure and soft consistency” (Ritter). A typical soil profile of this soil type would include “dark brown to black organic rich surface layers” (Ritter). The soil in this area has been used to alter the landscapes, and recently have been used for “cropland and pasture to

The project is located at an elevation of ~730 m above mean sea level and within the Basin and Range physiographic province (BR). The BR is composed of high relief mountains or foothills separated by low-lying valleys and salt flats. The salt flats of the Amargosa do not support plant life, but Phreatophytes (deeply rooted plants) occur on their edges and near the adjacent gravel-dominated alluvial fans. Iodine bush (Allenrolfea occidentalis) grows closet to the salt flats, while saltgrass (Distichlis stricta) and arrowweed (Pluchea sericea) occur more distal. The dominant species in the salt flat-proximal areas is honey mesquite (Prosopis juliflora) that occurs as large stands. Sacatone grass (Sporobolus airoides) and desert holly (Atriplex hymenelytra) intergrown with

Ultisols represent the basic condition of weathering and soil formation in the United States. They are found in areas with high precipitation and a long frost-free period like in the South. Particle size is small. These soils can be productive, but are found to be high in acidity. Leaching and erosion are often problems. They make up 9.2 percent of the soils in the

The forty (40) meter high cliff face visible at Sawn Rocks is the sheared off remains of a basalt lava flow from the (now extinct) Nandewar Volcano which dominated the area 21 million years ago. The column fractures are a result of the basalt cooling from the outside

Vegetation is important to conserve, especially in or near built up areas where it can easily become obsolete due to expansion or otherwise. In areas such as the Greenock region, South Australia, vegetation often gets split into fragments spread across the landscape. This has many implications for the conservation of both vegetation and animals in the region. In order to revegetate and conserve any vegetation in the area, a suitable site (or sites) must be chosen. Although it can be argued that conserving multiple fragments is appropriate in conservation strategies,

The Yarra catchment is north and east of Melbourne and covers approximately 4,046 square kilometers. It is split into three regions Upper, Middle, Lower. It is home to more than one-third of Victoria’s population and native plant and animal species, (Melbourne Water 2014) there is a large variety of land use
