Site conditions and growth of pines at the North East Cape Forests
1998
This study deals with a unique reconstruction of pine growth on various sites of the North East Cape Forests (NECF), thus providing information of strategic importance to the regional afforestation. The reconstruction of growth was possible in a number of plantations established by the former land owners in areas perceived to be marginal for industrial tree planting. In total, 21 survey sites were demarcated in stands of Pinus elliottii (14 sites), P. patula (6 sites) and P. radiata (I site). This study involved (i) determination of tree dimensions and tree condition, (ii) collection of dendrochronological information through stem analysis, (iii) detailed surveys of soils and other site characteristics, (iv) monthly measurements of soil water status at some of the sites, (v) data analysis with the major objectives to define the current yield, mean annual increment (MAI), and timber yield and MAI at harvesting age of 18 years, (vi) modelling of the growth-site relationships to predict site index (SI 18) an...
