Invasive species on Rottnest island?

The basin, rottnest island help!!?

• i am doing a society adn environment assignment on the human impacts of the basin in rottnest island, and i have to do an annoted field sketch. i have never been there, so i have to do a field sketch using a picture of the internet. however, we have to label teh cultural and natural features of the sketch and i was having some trouble idnetifying the things in the picture. for example, is the orangle building in the bottom right hand side of the picture a sheltered picnic are? and i'm not too sure what was random rocky platform is in teh distance of the picture. also, are those tea trees (the ones that look like christmas trees) and also, what kind of rocks are pictured?? and though this is stupid, is there a toilet facilities near the beach, and if so which direction?? what kind of vegetation is it as well? i know its a lot to ask, but if someone has been there and can remember what all those things are your help will be GREATLY appreciated. i've included the link for the picture... THANK YOU IN ADVANCE!! :) oh and just in case your wondering, i called the rottnest island authority to ask all these questions and they didn't get back to me though i tried a lot of times, so i've given up on them, and the only things on the internet focus on rottnest island as a whole, while i need to be specific to THE BASIN. kk thank you :) http://www.google.com.au/imgres?imgurl=http://www.panoramio.com/photos/original/391865.jpg&imgrefurl=http://www.panoramio.com/photo/391865&usg=__6hqTecraLeUBjLUir1HpVGfXUbU=&h=2016&w=3024&sz=1404&hl=en&start=14&um=1&itbs=1&tbnid=71Jza7xOebNY1M:&tbnh=100&tbnw=150&prev=/images%3Fq%3Dthe%2Bbasin,%2Brottnest%2Bisland%26um%3D1%26hl%3Den%26sa%3DN%26rlz%3D1T4ADBF_enAU301AU320%26tbs%3Disch:1

• Answer:

  Ok, the christmas looking trees are not tea tree, I'm fairly sure they are Norfolk Island pine http://www.conifers.org/ar/ar/heterophylla.html Other plants I could identify are & Images of plants for you I can see in the photo tussock of grass http://www.conifers.org/cu/call/preissii.htm http://en.wikipedia.org/wiki/Melaleuca_lanceolata Lagurus ovatus http://en.wikipedia.org/wiki/Lagurus_ovatus http://www.bio.mq.edu.au/ecology/rice/spinifex.htm This website gives all the information and better photos of the seating, gives a discription of the access, water, toilets etc. Hope this helps. http://www.rottnestisland.com/SiteCollectionDocuments/pdf/Disability_access_Basin.pdf
