context_page_description: Eucalyptus coccifera, commonly known as the Tasmanian snow gum, is a small to medium-sized tree endemic to Tasmania. It has smooth, grey and cream-coloured bark, elliptic to lance-shaped adult leaves, flower buds in groups of between three and nine, usually white flowers and conical, hemispherical or cup-shaped fruit.
context_section_description: The distribution of E. coccifera is limited by altitude: rarely will it be found lower than 800 metres (2,600 ft), or higher than 1,300 metres (4,300 ft) above sea level. 
  Around 1,300 metres (4,300 ft) the tree line is often unclear, and E. coccifera can be found in small stands or even as solitary trees. At these altitudes, E. coccifera generally grows to heights below 10 metres (33 ft), often blending into the alpine shrubbery at the highest reaches of its distribution.  A strong correlation has been found between increasing altitude and declining stem growth rate in E. coccifera.
  At the lower range of its altitudinal cline, E. coccifera has been observed growing to 40 metres (130 ft) in height, but it is more commonly measured at around 20 metres (66 ft), especially in sheltered sites on the Central Plateau and in Mt. Field National Park.
  Whilst individual and population tree height is the primary change in Eucalyptus coccifera at higher altitudes, observational studies have shown that with increasing altitude, the degree of leaf and bud glaucousness intensifies. This is most likely linked to the increased frost resistance of E. coccifera with increasing altitude. The juvenile foliage of E. coccifera is also more likely to persist for longer at high altitude.
