  1. excuse me but could u please tell me what year the hawksbury river has gotten polluted and how did it affect brewongle

    • Hi Danial, Thanks for your message – in regards to pollution in the Hawkesbury River – it has actually improved in the last 30 years due improvements in sewage treatment. Over 50 years ago the river carried far more nutrients and pathogenic substances that were harmful to humans – most of them coming from sewage treatment plants that dumped waste into the river. Our main pollution problems in recent times are high nutrient loads causing algal blooms and heavy rain events washing sediment into the river from western Sydney housing development. I hope this helps – Steve.

  2. How does the consequences of weather and other climatic conditions negatively impact the wildlife habitat?
    What alterations have been made to the land at brewongle eec and how has it impacted the land environmentally?
    What ways and man-made structures are present at brewongle eec to reduce the harm of those impacts?

    • Hi, These are good questions – I presume you have an assessment task to complete? Here are some thoughts to help you.

      How does the consequences of weather and other climatic conditions negatively impact the wildlife habitat?

      We have experienced the following in recent years – an increase in heavy rainfall events, severe storms, drought and increased number of very hot days above 40 degrees. These are all in line with climate changes occurring around the country. The impacts on habitat might include: Erosion (removing topsoil and some plants), tree fall from strong winds in storm events and drought causing tree death. This loss of large trees is a huge change to local habitat.

      What alterations have been made to the land at brewongle eec and how has it impacted the land environmentally?

      Think about the changes you may have seen on excursion – buildings, cleared areas, tracks and driveways and the impacts they will have environmentally. An example may be: Driveways cause soil compaction from cars, preventing growth of any plants for animal food or habitat.

      What ways and man-made structures are present at brewongle eec to reduce the harm of those impacts?

      You may have studied our habitat boxes – we have placed artificial habitat to make up for natural deficiencies. We have created ways to reduce erosion from tracks – channels and swales to direct water. Weed removal and native species planting have helped restore areas of bushland.

      Good luck – Steve.
