Analysis Of Euroley Bridge Ecosystem

Students of Yr. 11, Marian Catholic College biology class, took on the role of a field officer for the Department of Environment and Climate Change to investigate the biological community present near Euroley Bridge, Yanco. During their time, they were to observe the various organisms that are found in the ecosystem, taking into account their surroundings amid this process. They were provided with a booklet that had various activities which were intrinsic to their Field reports such as a site plan and a profile-transect. From their observations and notes, the students were to write a field report on Euroley Bridge Ecosystem including ways to preserve this biological community.
Distribution of plant species along the transect

Numerous different types of plant species and weeds were found in the Euroley Bridge Ecosystem touching the 30m transect. Some species appeared randomly along the 30m transect while other species were discovered clumped together. The species that appeared randomly included Poa Labillardier (Tussock grass, see image 1), Anthoxanthum Odoratum (Sweet Vernal-grass), Eleusine indicia (Goosegrass) and Sonchus Oleraceus (Sow-Thistle). The species that appeared clumped together were Foeniculum Vulgare Mill (Fennel) and Pittosporum …show more content…
The 1m by half quadrat showed that the Euroley Bridge Ecosystem is highly dense with an average of 84 percent ground cover. Ground cover is any sort of material found above the top soil. This demonstrates that 84 percent of the area in the Euroley bridge ecosystem is teeming with all kinds of miscellaneous organisms thus displaying that it is a highly stable ecosystem. Due to the high amount of ground cover, it can be postulated that the area is less prone to erosion. This is due to the fact that more ground cover means less prone to erosion (See image
