Ball's Pyramid - Fauna

Fauna

In 2001, a team of entomologists and conservationists landed on Ball's Pyramid to chart its flora and fauna. To their surprise they rediscovered a population of the Lord Howe Island stick insect (Dryococelus australis) living in an area of 6 by 30 metres (20 by 98 ft), at a height of 100 metres (330 ft) above the shoreline, under a single Melaleuca howeana shrub. The bush was growing in a small crevice where water was seeping through cracks in the underlying rocks. This moisture supported relatively lush plant growth which had, over time, resulted in a build up of plant debris, several metres deep. The population was extremely small, only 24 individuals. Two pairs were brought to two Pacific zoos to breed new populations. On the unsuccessful 1964 climb, Dave Roots had brought back a photograph of the insect, which the Australian Museum told him they thought was extinct.

Famous quotes containing the word fauna:

    The whole fauna of human fantasies, their marine vegetation, drifts and luxuriates in the dimly lit zones of human activity, as though plaiting thick tresses of darkness. Here, too, appear the lighthouses of the mind, with their outward resemblance to less pure symbols. The gateway to mystery swings open at the touch of human weakness and we have entered the realms of darkness. One false step, one slurred syllable together reveal a man’s thoughts.
    Louis Aragon (1897–1982)
