Conservation Status

Southern logrunners, although not threatened with extinction, dying out, are decreasing in population due to the clearing of rainforest for pasture and farmland. They are adapting by moving into places where exotic plants have been introduced and have spread into zones between cleared land and the remains of rainforests. Chowchillas, on the other hand, have not been affected by the loss of sections of their habitat through deforestation, the cutting down of trees. New Guinea logrunners are considered rare but this is most likely due to their shy nature and the remoteness of their territory.

SCLEROPHYLL FORESTS

Sclerophyll (SKLARE-uh-fill) forests, where logrunners live, are unique to Australia. These forests evolved, changed, in response to low levels of phosphorous, a chemical that encourages plant growth. Sclerophyll plants have hard leaves that contain lignin, a substance that prevents them from wilting. Dry sclerophyll forests have eucalyptus trees that are 32.8 to 98.4 feet (10 to 30 meters) tall with smaller sclerophyllic plants underneath. Eucalyptus (yoo-kah-LIP-tus) in wet forests are taller, over 98.4 feet (30 meters), and contain plants with softer leaves such as tree ferns.
