Whereas Papakura, Papatoetoe, Pukekohe, remain to be the suburban motif of Auckland. From the landscape point of view the difference in the urban and the suburban areas too are far more different to each other .
Main Body.
Spatial Change.
The concept of spatial change revolves around many factors on a particular site. It means the transformation of the species over time to adjust on a particular space. Plants too have the ability to change or adjust over a period of time to a particular environment. .
Ecological Gradient.
It is the degree of the change in condition of one particular factor from a lower concentration to high concentration. Gradients can seem more differing in factors such as temperature, dryness, wetness, saltiness, etc. .
At Eric Armishaw Park the change in gradients is seen in wetness and saltiness as the area is situated on a salt marsh near to the sea shore, it makes it more probable for salt water to enter the area near the ends of the park through the sea. The level of saltiness in which a plant can grow also varies from plant to plant.
Ecological Zonation.
The zonation of the park is put under salt marsh. As identified under the ecological zonation, the areas of the park is situated near to the wet banks and salt water from the sea in seen entering from different places at high tide. The zone is classified as identified by the vegetation.
Limiting Factors.
The limiting factor in Eric Armishaw Park is seen between the plants as they compete to establish quickly to occupy the area and compete for space and nutrients. For eg. There is competition between the Sea Rush (Juncus kraussii) and OiOi (Apodasmia similis) for faster growth and occupying the marshland. The other limiting factors that are essential for basic survival of the plants are degree of saltiness, food and nutrients, water availability. The plants in this area of the site have to heavily compete with each other for resources.
