1) Our first hand investigation of our local ecosystem is at the Mangroves at Point Frederick on Caroline Bay on the edge of St Edwards Catholic Collage.
2) PLANTS • Casuarina Tress • Sea Grass • New Zealand Spinach • Grey Gum Mangrove
ANIMALS • Oysters • Mud Whelks • Crabs • Toadfish • Leaches • Crustaceans • Ibis • Sand Hoppers • Fry (small fish) • Seagulls • Pelicans • Sea Snail • Shellfish • Small Prawns
DECOMPOSERS • Fungi • Algae
3) Estimated Population + Average count x Study area Per quadrat Quadrat area
64/7 = 9.142857143 Study Area = 52 x 96 = 4992
Estimated Population= 9.142857143 x 4992 1 = 45641 plants in area
The plant species I am estimating are Mangrove Saplings and Crab Holes.
