Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: VO Wasonga RK Ngugi DM Nyariki G Kironchi TJ NjokaA study was undertaken in Kenya's southern savanna rangelands to determine the seasonal effect of Balanites glabra canopy cover on aboveground grass biomass, grass species composition, soil organic matter and soil moisture content. The study was conducted during the period... -
Short-term response of burnt grassland to defoliation in a semi-arid climate of South Africa
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: HA SnymanThe impact of defoliation on the productivity and soil temperature of burnt grassland (head and back fires) was investigated over the short term (one and two growing seasons after burning). Head fires had greater flame height and rate of spread... -
Post-wildfire regeneration of rangeland productivity and functionality – observations across three semi-arid vegetation types in South Africa
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Johannes AD Breedt --- School of Biological Sciences, South Africa Niels Dreber --- School of Biological Sciences, South Africa Klaus Kellner --- School of Biological Sciences, South AfricaWildfires can have significant impacts on rangeland productivity and functionality causing substantial economic losses to affected farmers. In August 2011, such wildfires swept through the North West province of South Africa, destroying large areas of grazing and farm infrastructure. There... -
Volume equations and biomass estimates for three species in tropicalmoist forest in the Orientale province, Democratic Republic of Congo
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: T Kahindo Maliro --- , Democratic Republic of Congo J-P Lokombe Dimandja --- , Democratic Republic of Congo N Picard --- , GabonVolume equations predict the volume of the stem of a tree from dendrometrical characteristics that are easy to measure, such as diameter and/or height. These equations can serve as a surrogate for biomass equations, by converting the stem volume to... -
Biomass production and carbon storage of Populus ×canadensis Guinier I-214 plantations grown at Pogradeci region in Albania
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: E Toromani --- Department of Forestry, Albania M Sanxhaku --- Observatory of Meteorology, Albania M Sallaku --- Department of Biotechnology, Albania E Shaho --- Forest Engineer, AlbaniaFast-growing plantations of Populus ×canadensis Moench (syn. P. ×euramericana (Dode) Guinier ex Piccarolo) clone I-214 have good potential for biomass production. The objective of the study was estimation of biomass using allometric equations and estimation of carbon allocation according to... -
Fire and the dynamics of two unpalatable grass species (Cymbopogon pospischilii and Elionurus muticus) in a semi-arid climate
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Hennie A Snyman --- Animal, Wildlife and Grassland Sciences, South AfricaCymbopogon pospischilii and Elionurus muticus are unpalatable for most of the growing season and form a reasonably large component of the vegetation composition in semi-arid grassland areas. The influence of an accidental fire on the dynamics of these two grass... -
The long-term effects of fire regime on primary production of montane grasslands in South Africa
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Colin S Everson --- SAEON, South Africa Terry Everson --- School of Life Sciences, South AfricaNatural grasslands deliver essential ecosystem services through plant production, which enhances water supply, nutrient cycling, soil retention and greenhouse gas mitigation. Although the condition of montane grasslands for provision of ecosystem services is maintained by regular annual or biennial burning,... -
Temperate forest dynamics and carbon storage: a 26-year case study from Orange Kloof Forest, Cape Peninsula, South Africa
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Anabelle W Cardoso --- Department of Biological Sciences, South Africa Jeremy J Midgley --- Department of Biological Sciences, South Africa M Timm Hoffman --- Department of Biological Sciences, South Africa Coert J Geldenhuys --- Department of Forest and Wood Science, South AfricaTemperate forests are globally important carbon stores that are, in the face of recent improvements in their conservation, likely to increase their storage capacity in the future. Despite this, these ecosystems are poorly understood, especially over longer time periods. To... -
Changes in forest cover and carbon stocks of the coastal scarp forests of the Wild Coast, South Africa
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Kagiso Mangwale --- Department of Environmental Science, South Africa Charlie M Shackleton --- Department of Environmental Science, South Africa Ayanda Sigwela --- R3G, South AfricaLand-use intensification and declines in vegetative cover are considered pervasive threats to forests and biodiversity globally. The small extent and high biodiversity of indigenous forests in South Africa make them particularly important. Yet, relatively little is known about their rates... -
