Studies on the microbial ecology of soils from Pinus radiata (D. Don) forests
… Service became aware that stands of second crop Pinus radiata (D. Don) on some areas of the Moutere Gravel formation were showing slow growth and had a chlorotic appearance (Fig. 1.1). The second crop followed clear felling of mature P. radiata trees and were aged from 0 to 15 years (stone and …

Water use of Pinus radiata D. Don on bare ground at the Lincoln agroforestry experiment, Canterbury, New Zealand
… positions of Clone 3 and Seedling trees of Pinus radiata genotypes grown in bare ground during early summer (September 14 to 30 November) 1994. The predawn and mid-day plant water potential of two genotypes was also evaluated. Soil water storage was monitored weekly using Time-domain …

Analysis of a <i>Pinus Radiata</i> Seed Stock Field in the Native Año Nuevo Stand in California
… the pitch canker disease poses to the use of Pinus radiata D. Don in plantations in New Zealand, Australia, and Chile. A field trial of 264 seedstocks was planted adjacent to a native stand of pitch canker infected P. radiata on the central coast of California, and disease symptom development …

Efecto de los caminos y desechos forestales en el movimiento del coleóptero caminador, Parhypates (Eutamys) extenuatus (Carabidae)
… en un paisaje dominado por las plantaciones de Pinus radiata (D. Don). Es común que en los paisajes forestales industriales se encuentren caminos y fajas de desechos del manejo forestal. Estos pueden ser un serio problema para los más pequeños invertebrados con bajos rangos de dispersión, como …

A study of forest ecosystem development
… with time in a relatively simple ecosystem of Pinus radiata D. Don. on skeletal soils and integrades to Yellow-Brown Sands. Every endeavour was made to keep other soil forming factors (and the influence of other factors on the ecosystem) as constant as possible, thus satisfying the criteria for …

Development of a simulation model for drying deformation in radiata pine boards
Drying deformation of radiata pine (Pinus Radiata D. Don) boards results in a great loss of revenue to the wood industry. A computer simulation model, which is capable of predicting the drying quality of radiata pine boards, was developed for pregrading and for setting of drying schedules in …

Management Strategies for Pitch Canker Infected Año Nuevo Stands of Monterey Pine
<p>The future resilience of Pinus radiata D. Don (Monterey pine) is dependent upon the development of a silviculture program inclusive of either preventative or management techniques for the potentially fatal pitch canker disease (Fusarium circinatum Nirenberg and O’Donnell [=F.subglutinans …

Development of national extent terrain attributes (TANZ), soil water balance surfaces (SWatBal), and environmental surfaces, and their application for spatial modelling of Pinus radiata productivity across New Zealand
… important forestry crop in New Zealand is Pinus radiata D. Don. Until recently foresters have focussed on maintaining plantation management systems that are highly productive, while remaining sustainable. However, the new era of reduced carbon emissions and carbon trading means forestry …
