Alpine Vegetation Of Tasmania
Alpine vegetation refers to the zone of vegetation between the altitudinal limit for tree growth and the nival zone. Alpine zones in Tasmania can be difficult to classify owing to Tasmania's maritime climate limiting snow lie to short periods and the presence of a tree line that is not clearly defined.(Kirkpatrick 1982) Distribution Approximately 111 700 ha of Tasmania is alpine and subalpine habitat (2%). Australia wide, there is only 198 400 ha meaning 56% of Australia's alpine & subalpine habitat is restricted to Tasmania. The altitude at which alpine vegetation occurs ranges from 750m in the southwest to 1400m in the northeast. Classification From the Latin word Alpinus, from Alpes ‘Alps’. Globally, alpine vegetation is defined zone of vegetation between the altitudinal limit for tree growth and the nival zone.(Crowden 2005) In areas where mountains can be considered typically alpine, the vegetation zones are often divided into distinct altitudinal bands.

Alpine Vegetation
Alpine plants are plants that grow in an alpine climate, which occurs at high elevation and above the tree line. There are many different plant species and taxa that grow as a plant community in these alpine tundra. These include perennial grasses, sedges, forbs, cushion plants, mosses, and lichens.. Alpine plants are adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, wind, drought, poor nutritional soil, and a short growing season. Some alpine plants serve as medicinal plants. Ecology Alpine plants occur in a tundra: a type of natural region or biome that does not contain trees. Alpine tundra occurs in mountains worldwide. It transitions to subalpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as ''Krummholz''. With increasing elevation, it ends at the snow line where snow and ice persist through summer, also known as the Nival Zone. Alpine plants are not ...

Diselma Archeri
''Diselma archeri'' (dwarf pine or Cheshunt pine) is a species of plant of the family Cupressaceae and the sole species in the genus ''Diselma''. It is endemic to the alpine regions of Tasmania's southwest and Central Highlands, on the western coast ranges and Lake St. Clair. It is a monotypic genus restricted to high altitude rainforest and moist alpine heathland. Its distribution mirrors very closely that of other endemic Tasmanian conifers '' Microcachrys tetragona'' and '' Pherosphaera hookeriana''. Appearance and ecology ''Diselma archeri'' is a compact, prostrate shrub which commonly reaches 1–4 m in height but has been recorded to reach greater heights in subalpine rainforest zones. The foliage has a grey-green appearance with branchlets curving downward at their tips. Branches are short, ridged and very numerous. Branchlet foliage appears square in cross-section and scale-like leaves (2–3 mm) are overlapping and arranged in opposite decussate pairs whic ...

Proteaceae
The Proteaceae form a family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genera with about 1,660 known species. Together with the Platanaceae and Nelumbonaceae, they make up the order Proteales. Well-known genera include ''Protea'', ''Banksia'', ''Embothrium'', ''Grevillea'', ''Hakea'' and ''Macadamia''. Species such as the New South Wales waratah (''Telopea speciosissima''), king protea (''Protea cynaroides''), and various species of ''Banksia'', ''soman'', and ''Leucadendron'' are popular cut flowers. The nuts of ''Macadamia integrifolia'' are widely grown commercially and consumed, as are those of Gevuina avellana on a smaller scale. Australia and South Africa have the greatest concentrations of diversity. Etymology The name Proteaceae was adapted by Robert Brown from the name Proteae coined in 1789 for the family by Antoine Laurent de Jussieu, based on the genus ''Protea'', which in 1767 Carl Linnaeus derived from t ...

Ericaceae
The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with c.4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (''Erica'', ''Cassiope'', ''Daboecia'', and ''Calluna'' for example). Description The Ericaceae contain a morphologically diverse range of taxa, including herbs, dwarf shrubs, shrubs, and trees. Their leaves are usually evergreen, alternate or whorled, simple and without stipules. Their flowers are hermaphrodite and show considerable variability. The petals are often fused (sympetalous) with shapes ranging from narrowly tubular to funnelform or widely urn-shaped. The corollas are usually ra ...

Podocarpus Lawrencei
''Podocarpus lawrencei'' is a species of podocarp native throughout the Australian high country, from southern Tasmania through to the New South Wales highlands. Common names are Errinundra plum-pine and mountain plum-pine (though it is neither a pine nor a plum). It grows on exposed sites to 1,800 m, often forming living carpets over rocks through wind pruning. Mountain plum-pine can live up to 600 years, and the growth rings vary with the temperature of the growing season, with narrower rings indicating unusually snowy years. These factors make it useful for determining past climate conditions in the Australian Alps. Description The leaves are 1 cm long and 2–3 mm broad, green, often reddish-tinted, particularly so in cold winter weather. It has small bright red berry-like cones, with a 5–10 mm long red aril and one (rarely two) apical seeds 6–8 mm long; they are eaten by birds and marsupials, but are toxic to most other mammals (including humans) ...

Microstrobos Niphophilus
''Pherosphaera hookeriana'', or Mount Mawson pine (previously known as ''Microstrobos niphophilus''), is a dwarf conifer endemic to Tasmania, at altitudes above 600 meters. There are roughly 30 known sites, with population numbers in the tens of thousands. The species occurs in a range of habitats typically in areas near water bodies, mostly on dolerite derived soils. The species is highly fire sensitive and an increase in fire events associated with climate change may lead to local extinction and fragmentation of habitat. Description ''Pherosphaera hookeriana'' is a densely-branched erect shrub or small tree growing to heights of 5 meters, branches are often small and rigid with leaves arranged spirally and fully appressed to the stem. Individual leaves can measure up to 1.5 mm long, and 1 mm wide, leaves are thick, blunt and concave with a rounded keel. Male flowers form in compressed, terminal globular cones, ranging from 1–5 mm in diameter, with 8 to 15 fe ...
