(Stellenbosch : Stellenbosch University, 2021-12)ENGLISH ABSTRACT: This study aims to calibrate the 3PG (Physiological Processes Predicting Growth) model for Eucalyptus grandis x urophylla growing in the coastal Zululand region, South Africa. Parameter values developed ... -
The effects of repeated under canopy burning operations in commercial Pine plantations in Mpumalanga, South Africa on fuel loads and stand productivity
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Wild fires are a risk to commercial forestry companies in South Africa resulting in commercial areas being damaged or destroyed. Viable methods to mitigate this risk in an effective, economical and ... -
Non-destructive methods for predicting sawn lumber properties from young, standing Eucalyptus grandis and Eucalyptus grandis X urophylla trees.
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Eucalyptusis the most widely planted hardwood genusin South Africa cultivated for both sawn lumber and pulp. It is known for its fast growth but is prone to high growth stresses and other problematic ... -
A conceptual framework for environmental service payments in South African plantation forests
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Plantation forests contribute to supplying environmental services and goods such as carbon sequestration, clean water production and hydrological cycle regulation. Environmental services are the ... -

(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: With the increasing movement towards environmentally friendly and sustainable building materials in the construction industry, engineered wood products have become a preferred structural ... -
Predicting growth and future yield in Eucalyptus grandis x urophylla stands using the CABALA process-based model
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: The aims of this research were to (1) partly parameterise and initialise and (2) test the CABALA process-based model for hybrid Eucalyptus grandis x urophylla clones in the Zululand region of South ... -
An investigation into shrinkage and collapse behaviour of Eucalyptus grandis and Eucalyptus grandis x urophylla wood
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: Only 1 % of land is used for forestry in South Africa and the country might experience a shortage of structural softwood sawn timber in the near future. Despite this, South Africa actually produces more ... -
Co-production of furfural and wood composite products from bio-based processing residues
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: There is an increased environmental concern to move from a petroleum-based economy to a more bio-based economy. Lignocellulosic materials have been shown to be a good source of building blocks for value-added ... -
