Journal Article
TL;DR: In this article, a quantitative assessment of soil machine trafficability was conducted near Tumut and the results indicated that if the ratios of the soil strength to ground pressure applied by the logging vehicle exceeded 7.0, then logging operations could proceed within the current environmental constraints.
Abstract: Costs associated with machine downtime and the need for stockpiling during winter logging can be reduced by better planning of logging operations based on a quantitative assessment of soil-machine trafficability. Trials conducted near Tumut indicated that if the ratios of the soil strength to ground pressure applied by the logging vehicle exceeded 7.0, then logging operations could proceed within the current environmental constraints. Measurements and simulations of the daily variation in soil moisture and soil strength were undertaken for a range of soils in the region. (...)

Journal Article
TL;DR: Provenance of P. caribaea var. hondurensis had a higher density than wood from the Honduran and Nicaraguan coastal provenances at both locations as mentioned in this paper.
Abstract: (...) Provenances of P. caribaea var. hondurensis Barr. and Golf. produced significantly more volume under bark than provenances of P. caribaea var. bahamensis Barr. and Golf. and P. caribaea var. caribaea. Wood from certain inland provenances of P. caribaea var. hondurensis had a higher density than wood from the Honduran and Nicaraguan coastal provenances at both locations. (...)
