Introduction
Sugarloaf area belongs to the area of Lane Cove National Park, which is famous for biological conservation. This area is a part of a land, which is very traditional of Guringai people. Their country has been extended from Newcastle to the main art of Sydney. This area is famous for public appreciation along with well-being and personal enjoyment as well as a site for valuable research process. There are a number of ecosystem present in this area that delivers the basic need of the habitat for the native species like flora and fauna.
Even some of these species are declared as threatened species; as for example red-crowned toadlet, Black-chinned Honeyeater, Grey-headed Flying fox. Other species like long nosed bandicoot resides in an isolated area of this nation park. This area is totally su
ounded by the u
an development and the most of the Sugarloaf was spoiled before the formation of national park. In this study the Sugarloaf side location and te
ain and vegetation data has been discussed and analyzed.
Primary and Secondary Data Findings
Sugarloaf Study Site Location Te
ain and Vegetation
The study side is Sugarloaf area, which is under Lane Cove National Park, which is located within metropolitan Sydney. As per the view of Dunstan, Howard, Hardy, Giles and Burgess (2016), this national park is positioned in 10 km su
ounding of Sydney business district, which is featured with a number of vegetation such as heathland, wet sclerophyll and dry forest, mangroves as well as tidal flats. The land of this park is the bank of Land Cove River where tidal flats formed and the stream flows in south to east direction in the ha
or of Sydney.
This national park offers a number of prospects for the residents of Sydney along with visitors can experience a lot of variety in nature and can enjoy a good time with their family and friends. People enjoy boating, biking, picnic, playing and a lot of things, which ensures those visitors to visit the places a many times. According to the idea of Weitzman, Sandmeier and Tracy (2018), the landscape of the area is
eath-taking and it presents a large u
an atmosphere where people can see forest with verities of eucalyptus forest where Casuarina woodland, water land, saltwater and backwaters make this place very attractive and make the home of different birds and animals.
There are three kinds of vegetation in the area, which are grassland, sandstone forest and shrub lands. The te
ain portion, which is above 2000 m is mainly covered by grassland though there are varieties small patches of forest around the area of national park. According to Lloyd-Walker and Walker (2016), a large portion of this park is rugged te
ain in the slope of the lane cove river. The part of the park is a part of KU-ring-gai and the government area and a small area of this park is in Willoughby and the Hunter’s hill, which is the area of the local government. There are developed subu
an area located su
ounding this park and the upper portion of northeast region is covered by dense bush.
Some of the park is affected by infestation of weed. The characteristic of the bush depends on the type of land and the soil characteristics as well as on the topography of the land. According to Lewis (2016), hence, in this study all these vegetation will be studied and the type of vegetation are different as they are situate din a specific region of the park. There are 49 sites where the survey work can be organized and among those sites there are 36 sites, which is sampled for different species like frogs, bats, reptiles, birds.
According to the statement of Hernandez-Agreda, Leggat, Bongaerts and Ainsworth (2016), there are around 90 hectors land, which is filled by bush land that is generally situated in creeks and in river shore. There are 625 indigenous plants that includes wet forest and dry forest that’s
ings native animals and native people closer. In map, it is situated between Marsfield and Pymble in Sydney.
Two Organisms and Their Habitat Needs
There are two hundred and sixteen organisms present as a native te
estrial species who are known to reside in the area. As per the idea of Toro-Farmer et al. (2016), the most threatened species of this area is red-crowned toadlet. It is a category of small frogs measuring 30 mm and the toadlet that are black, which reach 25 mm. The term cryptic means the exceptional marking of the species foe, which the species can be distinguished from other species. In case of red crowned toadlet the species can be identified by the color orange and red triangle as well as the ‘T’ shaped mark on the head of the species and there should be stripes on their back side, which shows the same color.
There is ma
led white and few black striking pattern on their belly portion. This red crowned toadlet is specially restricted to the sandstone area of Lane Cove National Park. The tadpoles, which are red crowned hatches and is developed when there is heavy rainfall. The frogs who are men they normally stay near the eggs, which are in developing stage because they want to defend their eggs from the strangers and they start to fight if any serious circumstances arises. According to Scida and Gration, (2018), they defend the
eeding site to make female safe and their eggs secure. They occur in the open forest, which is mostly on Na
abeen Sandstone. They inhabits generally in wet drainage line under the sandstone ridges, which have shale capping.
As per the statement of Daly, Owers and Horton (2015), they gets their shelter under the rocks, which is among the mass of dense vegetation and the thick piles vegetation of leaf. They
eads in dense mass of vegetation and they have not been seen to
ead in water ever. This species are seen as a small colonies, which is in scattered format. As they stay as a distinguished colony, this population concentrates in a relatively small area.
The second studied species is the black chinned honeyeater, which is a species of passerine bird. This is endemic of Australia and they are the largest amongst Melithreptus honeyeaters considering the mainland. The...
