“Bicentennial Park is a diverse natural property”(1) which studies the ecosystem of mangroves, saltmarsh and other biotic and abiotic factors. Bicentennial Park is located in Sydney Olympic park, NSW Australia. “The state and federal government created the Park during 1980s, to celebrate Australia's Bicentenary in 1988”(2). “On 1 January the Park was officially opened”(3). “This large up-to-date park consists of 100 hectors of inheritance land”.
Mangroves are among the endangered habitats in the world, there are 64 types of mangroves in the world, and Bicentennial Park has 2 types. Like the mangroves salt marsh is also an endangered species, it is a filtering system for nearby rivers and streams and supplies nutrients to fish and other aquatic species. “The Badu mangrove board walk allows people to walk through one of the largest remaining mangrove ecosystem beside the Parramatta River”(4).
Aim: To study the mangrove ecosystem by: * Measuring the abiotic factors at different locations. * Estimating the abundance of a plant and animal species. * Describing the distribution of a plant and animal species. * Identify the relationships between the abundance and distribution of a plant and animal species. * Describing how abiotic factors affect the distribution of organism.
Method:
Different test where executed: Measuring the abiotic factors at different location:
We measured different types of abiotic factors in the saltmarsh community and in the mangroves ecosystem. Here are the types: Soil temp, soil moisture, light intensity, wind velocity, air temp and humidity. * Soil temp: equipment (Soil thermometer probe).
Take the reading of the probe which was in the ground. * Soil moisture: equipment (Soil moisture meter). Take the reading of the meter which is in the ground.
* Light intensity:
