Almaciga (Agathis dammer) populations were at their densest between 500 m and 700 m. Although the population structure of this species appeared healthy, its continued survival in the Mt. Beaufort - Thumb Pk. area is seriously in question.
Extensive and intensive resin tapping of trees down to 5 cm in diameter at breast height has resulted in not only insect and fungus invasion of the heartwood, but even effective ring-barking. Dying emergent individuals with core rot and fungal fruiting bodies on the trunk were frequently encountered, as were dead specimens without bark. The situation is so acute that
Almaciga may soon disappear from this area.
