Roadside Chipping in a First Thinning Operation for Radiata Pine in South Australia
نویسندگان
چکیده
Nacrtak Roadside chipping is a common harvesting system to produce chips in Australian plantations. This study investigated the productivity and cost of road-side chipping operation (chipping logs extracted by forwarder to the road side) using a Morbark chipper with flail delimber in a first thinning of Pinus radiata stands. An elemental time study method was used to collect the time working cycles. The regression approach was used to develop the productivity predicting model based on the log size in different wood piles. The statistical analysis yielded an average productivity of 59.4 GMt/PMH0 with the corresponding costs of 5.2 AU$/GMt for the Morbark chipper. The details on work time analysis, relocation time and fuel consumption of the machine are documented in this paper. The results provide basic information for planning roadside chipping operations in pine plantations.

Better information regarding the spatial variability of height, Diameter at Breast Height (DBH) and stocking could improve inventory estimates at the operational Planning Unit since these parameters are used extensively in allometric equations, including stem volume, biomass and carbon calculations. In this study, the influence of stand stocking on height and DBH of two even aged radiata pine (...

Nacrtak Roadside chipping is a common harvesting system in Australian plantations, which utilizes a mobile chipper stationed at the field edge to produce high-quality pulp chips for export. The studied harvesting system included a feller-buncher, two grapple skidders, a flail-debarker and a disc chipper. The study goals were to determine machine productivity, operation costs, fuel consumption, ...
متن کاملComparison of genotypic diversity in native and introduced populations of Sphaeropsis sapinea isolated from Pinus radiata
Sphaeropsis sapinea is an endophyte and latent pathogen of pines, assumedly introduced to the Southern Hemisphere along with its host. There are at least three recognised forms of S. sapinea that differ from each other morphologically and can also be separated based on molecular characteristics. Pinus radiata is a native to California but has been used extensively for afforestation in the South...

The pitch canker fungus Fusarium circinatum was first associated with mortality of P. radiata in California during the 1980s. Since then it has been dispersed to several countries of the Northern hemisphere together with South Africa and Chile in the southern hemisphere. In Chile the disease caused mortality of seedlings in P. radiata at nursery, and in South Africa the pathogen has already com...
