The increased removal of forest-derived biomass with whole-tree harvesting (WTH) has raised concerns about the long-term productivity and sustainability forest ecosystems. If true, this effect needs to be factored in assessment feasibility implement such a drastic management measure. Therefore, economic performance five experimental plantations three different types, where 1971 simulated WTH ev...

This experiment was conducted to bring in a suitable and economic agarwood oil extraction method for Agar tree (Aquilaria agollocha) growers in Bangladesh. Agarwood was collected from Fotikchori upazila of Chittagong district and a prototype of hydro-distillation extraction chamber was developed at the lab of Department of Farm Power and Machinery, Bangladesh Agricultural University, Mymensingh...

In many living trees, much of the interior of the trunk can be rotten or even hollowed out. Previously, this has been suggested to be adaptive, with microbial or animal consumption of interior wood producing a rain of nutrients to the soil beneath the tree that allows recycling of those nutrients into new growth via the trees roots. Here I propose an alternative (non-exclusive) explanation: suc...

The Brown Tree Snake (Boiga irregularis) has caused ecological and economic damage to Guam, and the snake has the potential to colonize other islands in the Pacific Ocean. This study quantifies the potential economic damage if the snake were translocated, established in the state of Hawai‘i, and causing damage at levels similar to those on Guam. Damages modeled included costs of medical treatme...

Surveys found that large contractors replace approximately 10% of their equipment fleet units annually in North America. Cost minimization model is a commonly accepted method for equipment replacement which helps to identify these equipment units whose total owning and operating cost reaches their minimum point as candidates for replacement. While the model is conceptually clear with the aim of...

Saltcedar (Tamarix spp.) is a widespread invasive plant found in riparian corridors and floodplains in 16 western states. In addition to being associated with such problems as increased soil salinity and decreased plant diversity, saltcedar has been reported to be a prolific water user. Popular press articles widely report that each individual saltcedar tree can use as much as 757 L (200 gallon...
