The landscape ranges from eucalyptus temperate rainforest to alpine moorland, rising to 1,434 metres (4,705 ft) at the summit of Mount Field West.

[5] During the Pleistocene period, a snowfield covered the top of the Mount Field plateau and fed glaciers in the surrounding valleys.

[6] A large, 12 km long glacier formed the broad river valley and the cirque walls above Lake Seal.

Although rarely acknowledged, the great majority of plants in Mount Field National Park (indeed in the world) form mutually beneficial mycorrhizal relationships with fungi.

Two hundred and eighty-nine species have already been recorded by field naturalists and interested individuals and a list can be found in the Atlas of Living Australia.

The Green Elfcup (Chlorociboria aeruginascens group) is found growing on rotten wood in wetter parts of the park.

The Australian citizen-science organisation, Fungimap is documenting and mapping the distribution of fungi including those that occur in National Parks.
