Brown Root Rot Disease in American Samoa's Tropical Rain Forests

Brown Root Rot Disease in American Samoa

Phellinus noxius causes root and lower stem rot of woody plants throughout the South Pacific region. Its hosts include rubber, mahogany, cacao, and many timber, fruit and landscape trees. Though endemic to the tropics, we found no reports describing brown root rot disease in native forests, exclusively. Incidence, distribution and host range of P. noxius were measured in primary and secondary r...

Armillaria Root Rot in Eucalypt Forests: Aggravated Endemic Disease!

Species of the woody root rot fungus Armillaria are indigenous in cool temperate rain forest, mixed forest, and wet and dry sclerophyll eucalypt forests in Australia. Four species have been described or identified from southeastern Australia: A. luteobubalina Watling and Kile, A. fumosa Kile and Watling, A. hinnulea Kile and Watling, and A. novae-zelandiae (Stevenson) Boesewinkel. The latter sp...

Modelling Selection Harvesting in Tropical Rain Forests

VANCLAY, J.K. 1989. Modelling selection harvesting in tropical rain forests. Long term yield estimates for natural forests require a harvesting model to enable future yields to be estimated reliably. The model should predict the felled stems, the proportion of these which are merchantable, and any damage to the residual stand. Regression analyses was used to develop a model of current logging p...
