There are two primary methods for capturing information on land cover: field survey and analysis of remotely sensed imagery.
This information is then updated regularly to monitor the evolution of the land cover and the management of the crops.
As a result of the superior land cover, they have far smaller ranges than their southern relatives.
"The natural land cover holds more heat than the agricultural areas, making the freezes less frequent and their durations shorter."
Most of the land cover in the area is woodland or grassland.
Selangor is the most developed state in Malaysia but it still retains approximately 30% of its land cover under natural forest.
The sandy soil, grassy land cover, and dry weather supported cattle grazing.
A study showed a substantial reduction in natural land cover between 1970 and 2010, combined with a significant increase in population.
The leaves then regrow during the dry season and provide land cover and shade for crops.
Currently, his main research interests are global change, predictive mapping of land cover, and land degradation.
