Impacts of Mechanical Tree Felling on Development of Water tipelo Regeneration in the Mobile Delta, Alabama
Two water tupelo (Nyssa aquatica L.) stands in the Mobile Delta of Alabama were selected to test the hypothesis that mechanizedfelling does not reduce establishment and growth of natural water tupelo regeneration relative to traditional tree felling with chainsaws. To test the hypothesis, we established six, 2 ac treatment plots in each of two blocks on each of two sites, and randomly assigned ...
متن کاملTree regeneration in felling and natural treefall disturbances in a semideciduous tropical forest in Mexico
Tree regeneration was compared among closed-canopy sites and 4±11-year old natural and felling gaps in a selectively logged semideciduous tropical forest in southeastern Mexico. Closed-canopy sites and gaps were selected strati®ed randomly. In addition, all large natural and felling gaps encountered were sampled. All stems 5 cm dbh were sampled in sets of 10 m plots in closed-canopy sites and g...
متن کاملPerformance, Capability and Costs of Motor-Manual Tree Felling in Hyrcanian Hardwood Forest
Nacrtak Motor-manual tree felling is the most labor-intensive component of all harvesting operations and frequently represents a bottleneck in wood production. The study of motor-manual tree felling was carried out in two compartments in the Namkhaneh district of Kheyrud Forest. The objects of this study were as follows: time study of tree felling operations, estimate of chainsaw productivity a...
متن کاملcomparison of noise exposure levels on chainsawers in motor-manual tree felling (case study: hyrcanian forest)
chainsaw is an important machine for tree felling limbing and bucking in hyrcanian forest and the major problems related to using forest machines was sound intensity. the aim of this study was to measure the sound level in occupational exposure of workers, determine the exposure time of workers and comparison of the variables among the workers. this study was carried out in namkhaneh district i...
متن کاملPortable Manipulator Systems for Remote Maintenance at the ORNL Spallation Neutron Source Project
Early in calendar year 2004, TPG Applied Technology will deliver two manipulator systems to the Spallation Neutron Source (SNS) project in Oak Ridge, Tennessee, for use as remote maintenance systems when the SNS becomes operational in 2006. One of these manipulator systems will be a boom system mounted on a pedestal with a dual-arm dexterous manipulator mounted on the end of the stick. The othe...
