The Waitakere Ranges are home to many flora and fauna. These plants and animals make up the communities within their ecosystem. They interact with each other through competition and various relationships. In the Waitakere Ranges, there are several habitats organisms live in: Forests and shrub lands Freshwater wetlands, lakes and streams Coastal wetlands, dunes, and estuarine tidal flats and channels Urban area The populations of each habitat vary, as they would be dependent on abiotic factors such as: light, temperature, water and soil. Within communities, organisms compete for limited resources (food, space, mates, shelter). 613 of our native species (plants, birds, fish), compete with 240 introduced plant species, 19 introduced bird species, 9 introduced mammals and 2 amphibians. It is estimated that we have lost 30 native bird species due to this competition.…show more content…
Next, primary consumers such as snails and weta eat producers, consuming their nutrients. Secondary consumers, such as Kereru, Tui and Long Tailed-Bats then consume these insects, with energy passing through the food chain to them. Tertiary consumers - such as stoats and possums - are pests to our native species as they are threats to populations of our native birds. Pests in the Waitakere ranges include wasps, mould, rats, goats and pigs. These species are considered predators and parasites, these species benefit while their prey species is harmed. Wasps and mould kill native trees for shelter and food. Rats, goats and pigs prey on native species of birds, insects and fauna. Predation by introduced species of native species both threatens native populations, but also the balance of the ecosystem. With predatory niches being taken, these pests not only threaten their prey, but also native
