Flora and Fauna
orinna provides a paradise for naturalists, artists and photographers. There is much to learn about rainforest history, ecology and management. We thank Forestry Tasmania for some of the following information and refer readers to their website, http://www.forestrytas.com.au.
Enthusiasts might also wish to view the Cradle Coast Natural Resource Management Strategy 2005. Corinna sits in secondary rainforest (much of the primary rainforest was cleared when miners occupied the town), and is the northern most point where huon pine is found.
Cool temperate rainforest is different to the warmer climate rainforest, which is dominated by large varieties of animal and bird life, as well as a multitude of tree and plant species. By comparison, Tasmania’s rainforests contain only a few dominant tree species, which include leatherwood, celery top pine, sassafras, king billy pine, huon pine, myrtle beech, pencil pine, native laurel, soft tree fern, slender tree fern, blackwood, cutting grass, native plum, whitey wood and the commonly named, “horizontal”. Some eucalypt species like the mountain ash, will grow in rainforest conditions. An understory of ferns, mosses, liverworts and fungi form an important part of the rainforest habitat and ecosystem. A trip to Corinna in April to June exposes a wonderland of more than 60 species of fungi and many rare and endangered lichen species.
Rainforests are self-perpetuating communities, but have been subject to human modification and damage for the last 30,000 years. Rainforests require the absence of repeated fire to exist – with full regeneration only possible after a fire free period of 100 to 200 years. It is believed that parts of the rainforest around Corinna have never seen fire. With a drying climate, the threat increases, and there are also various fungal diseases spread by humans that can contribute to the decline of certain species such as the myrtle.
There are only a few mammals and birds in the cool temperate rainforest of the Tarkine, but the cool damp conditions make an ideal environment for a multitude of invertebrate species. Freshwater crayfish, burrowing yabbies, large land snails and walking worms can be seen in the temperate rainforest of the southern Tarkine. Mammals such as ringtail possums, Bennett’s wallabies, wombats, devils, spotted tail quolls and dusky antechinus can be found fossicking for food. The lawns at Corinna come alive with wallabies at dusk. Reptiles and amphibians such as the tiger snake, metallic skink and Tasmanian tree frog can also be found. Platypus frequent the Pieman and its tributaries.
About twenty bird species can be found in the Tarkine rainforest including the black currawong, green rosella, olive whistler and grey goshawk. The rare and endangered orange bellied parrot can be found around Corinna, which also is home to many blue wrens. On the Pieman, the white bellied sea eagles nest and have a commanding presence, and often an azure kingfisher can be spotted. Other coastal birds include pacific gulls, black swans, little terns, oyster catchers and seagulls.
