Population Study
Mount Henry Peninsula is an area of significant biodiversity. The various plant species that are found in this region rely on a specific combination of abiotic and biotic factors. Plants found in one location may not necessarily occur in another, where the conditions are different.
The following extract is part of a study commissioned by the City of South Perth.
“The Mt Henry Peninsula and its associated foreshore is the largest area of bushland in the City of South Perth and is also an area of high regional conservation value. The study area incorporates several different vegetation communities including highly saline seasonal wetlands and Banksia woodlands. It forms an important remnant habitat for bird and other animal species, as well as providing important corridors for movement of native fauna within the highly fragmented habitat remaining in the Metropolitan area. An ethnographic report for Brooker et al. (1993) revealed that the Peninsula was a Nyungar hunting and fishing ground and as it has not been significantly altered since European settlement, it has special interest for Nyungar people”.

Task 1: Estimating population
In a group of 2-4 people, choose any two plant species for which you will conduct a population survey. The plant species should be common enough so that a census survey would be impractical.
Identify the study site using GPS coordinates and display this suitably on a map. Conduct an appropriate population study using quadrats.
Task 2: Abiotic and biotic measurement
Construct a survey of the study site in order to determine how the abiotic conditions change throughout the landscape. Develop a profile of the soil type, availability of light, wind and any other significant features using transects and instrumentation.
Communicate your findings in a report outlining clearly the method you used, results suitably displayed. Comment
