The national park is made up of 950 hectares of Cumberland Plain Vegetation and it consist of many type of pest plants such as African olive‚ blackberry and lantana‚ vines such as balloon vine and bridal creeper etc. There have been over 140 animal species recorded at the park such as vulnerable swift parrot and turquoise parrot

Soil is defined as that part of the unconsolidated material covering the surface of the earth which supports plant growth. It has three major constituents. (1) Solid Particles (Salts‚ mineral and organic matter)‚ (2) air and (3) water. The type of soil formed is a function of topography‚ climate vegetation and the parent rocks

Soil Erosion Soil erosion will bring impacts when water is still plotted on the road surfaces. Roads with steep hills or terrain without the contours design will bring erosion as the road cracks. Multiple tracks will prevent the water. The ruts may bring to soil erosion problems. The tracks occur is paid to keeping standing water off the

Flood is a serious type of environmental degradation in our country. Environmental problem is directly related to surface water. As result of the excess amounts‚ sometimes flowing water breaks its embankment and overflows into nearby lands as flood. A large numbers of rivers flowing directly from the Himalayas. Every year‚ during the monsoons‚ many of these rivers flood

valley. The river is wider and has a deeper channel as more lateral erosion has occurred. The velocity is greater than that of the upper course as there is a greater volume of water in the river (because of tributaries flowing into the river and surface run off) and less energy is used overcoming the lesser friction of the smoother less angular bedload. There is more transportation of material‚ and more suspended sediment. The bedload is smaller and more rounded as it has been subjected to more erosion

Surface Tension Properties of Liquids Introduction The purpose of this experiment is to measure and record the surface tension of water and other aqueous solutions using capillary rise method techniques and practicing lab safety. In this laboratory the surface tension of water depends on the concentration of the following solutes; NaCl‚ acetone‚ and sodium dodecyl sulfate (SDS). Intermolecular interactions as well as other phases (solid‚ or air) make a liquid exist. The data collected will show

Duckweed is a simple‚ aquatic plant that consists of two-to-three small thalloids‚ or plate- like leaflets that floats on or just under the surface of the water‚ which may or may not have simple rootlets. As I have mentioned‚ the scientific name for duckweed is Lemnaceae. Lemnaceae is from the order Alismatales‚ and the family Araceae. The largest thalloids can get up to ¼ of an inch‚ while the
