The Dargo High Plains are a much loved part of the Victorian high country, with extensive open plains surrounded by eucalypt forests, much of which is dominated by Alpine Ash (Eucalyptus delegatensis). Alpine Ash is one of the iconic trees of the Victorian mountains, where it is widespread and often dominant in grassy or wet subalpine forests, in deep fertile soil, often on slopes, and where it commonly forms pure stands. In Victoria it occurs at altitudes between 900 and 1,500 m (3,000 and 4,900 ft). The high points of the Dargo High Plains sit roughly between 1,300 and 1,500 metres above sea level.
Only 0.47% of old growth Alpine Ash still exists in the forests of the Central Highlands. In the mountain ranges of north eastern Victoria and East Gippsland, old growth Ash is now rare, and ‘tens of thousands’ of hectares of forest are on the verge of ecological collapse.
Sections of the Plains have burnt several times in recent years, including the summer of 2018/19. Considerable sections of the Plains Ash forests have been logged in the past. Now, the state government has scheduled a number of logging coupes of long unburnt forest, which threatens to devastate the fringes of the high plains.
The logging program in the High Plains area appears to include roading through the Alpine National Park to access the coupes on the east side of the plateau.
