Bulimba Creek Case Study

ulimba Creek is the largest creek in Brisbane measuring to only 122km². It is located in the eastern and south-eastern areas of Brisbane and generally flows northwards into the Brisbane River. There are also a number of significant wetlands systems in the catchment in the upper and in the lower catchment. The creek is, at present, affected primarily by urban and mechanical advancement. In the past the creek hallway was broadly cleared for crops and after that grazing in the early moments of the most recent century with some remainder of vegetation remaining. In a few territories the diminishment in provincial businesses has permitted riparian vegetation to regrow.

In order to determine whether Bulimba Creek is a healthy ecosystem, we tested and recorded most abiotic and biotic

Generally riparian zones are restricted pieces of area that line the fringes of a water source. Riparian fauna are frequently not the same as those found in nearby groups like the water-rich soils found in the riparian zone. Healthy riparian zones give an assortment of critical environment services and they are mostly vital, natural surroundings for wildlife. We are studying this area to see if there is a range of characteristics that indicate whether or not the water is healthy. A few signs of a healthy riparian zone are ; a thick growth of vegetation with diverse species of grasses, forbs (weeds), shrubs, and trees that cover the streambanks and provide shade, land surrounding streambanks generally remains wet throughout most of the year except where streams cut through rocky terrain, Streambanks are more vertical and steep than flat and rounded. Stream water is relatively clear but contains debris from streambanks (leaves, twigs, or logs) that create pools and other habitat for fish and aquatic insects. A diversity of wildlife including fish, aquatic life, mammals, and
