New map of world vegetation reveals substantial changes since 1980s

Monday, 15 August 2016
[font size=3]A University of Otago botany researcher and colleagues have developed a new system to map the world’s “biomes”— large-scale vegetation formations — that will provide an objective method for monitoring how vegetation reacts as climate changes.
The system uses satellite observations of the timing and intensity of vegetation activity and how this relates to temperature and soil moisture to classify the world’s vegetation into 24 biome types.
Several other global biome maps exist, but the researchers’ goal was to produce one that is not reliant on expert opinion or correlations between vegetation and climate.
Botany Professor Steven Higgins says they used their new classification scheme to examine change in biomes over time and found that 13 per cent of the Earth’s land surface changed its biome state over the last three decades.
