The purpose of my investigation is to accurately measure the abundance and distribution of one animal and plant species from the Thirroul/Austinmer rock platform, a local ecosystem.

I aim to achieve experience and gain knowledge in the function of methods used when measuring the abundance and distribution of these biotic factors.

The animal species I have chosen in the Black Periwinkle (Melanerita Melanotragus) and the plant species, Neptunes Necklace ( Hormosira banksii

I strive to measure the distribution and abundance of each other these species as accurately as possible.

Methods

The methods I chose to use measure these factors include:

  1. A transect line for distribution. This involves measuring where the species is situated across a line in the area, revealing where the species population is concentrated or blatantly evident. On a map sketch of the rock platform, a symbol is drawn for wherever a species lies, and is later graphed so clearly show where the population of the species is most dense.
  2. A quadrat for abundance. For this method I have decided to use a square metre as my area of measurement.
