Remote sensing is viewed as a cost-effective alternative to intensive field surveys in assessing site factors that affect growth of Eucalyptus grandis over broad areas. The objective of this study was to assess the utility of hyperspectral remote sensing to discriminate between site qualities in E. grandis plantation in KwaZulu-Natal, South Africa. The(More)
The ability of various ecosystems to perform vital functions such as biodiversity production, and water, energy and nutrient cycling depends on the ecosystem state, i.e. health. Ecosystem state assessment has been a topic of intense research, but has reached a point at which accurate large scale (e.g. regional to global scale) modelling and monitoring are(More)
The ability to map vegetation to the species level is of wide interest in Ecology. Species-level maps of vegetation have important applications in resource inventories, biodiversity assessment, and fire hazard assessment. Species mapping with remote sensing is based on the assumption that each species has a unique spectral signature. Spectral signatures of(More)
The stability of remote sensing indicators of leaf water, chlorophyll and nutrients to discriminate between Eucalyptus grandis growing on different site qualities in KwaZulu-Natal, South Africa was evaluated for two growing seasons (winter and early summer). Site quality was defined by the total available soil water (TAW). Canopy reflectance spectra for 68(More)
