Alpine plants and animals
The park has over 200 species of alpine flowering plants and provides important habitat to nationally endangered species, such as southern corroboree frogs and broad-toothed rats. Ancient snow gums, twisted and stunted from the blasting effects of wind, snow and ice, mix with alpine ash and fragrant alpine mint bush. Above the treeline only heath, snow grass and the hardiest plants face the cold. Slow-growing mountain plum pine, some over 500 years-old, cling to boulders for warmth, providing shelter and food for threatened mountain pygmy-possums. Bogs of spongy sphagnum moss soak up the snow melt, to be released into alpine streams. From late spring to early summer, the heath is dotted with patches of wildflowers like alpine sunrays and snow daisies, yellow billy buttons, and the anemone buttercup, found only in Kosciuszko National Park.
