Malaysia is a tropical country with diverse climate, hydrology, and ecosystem. Malaysia, located near the equator, generally has climate characteristic features of uniform high temperature, high humidity, and copious rainfall throughout the year, although the geography of Malaysia may spell variations in the microclimate of the regions in the country. Being a maritime country close to the equator, Malaysia naturally has abundant sunshine and, thus, solar radiation. The cloud cover cuts off a substantial amount of sunshine and, thus, solar radiation. Among all the factors affecting the rate of evaporation, cloudiness and temperature are two most important factors in this country. Flora is defined as the plant life occurring in a particular region or time, generally the naturally occurring or indigenous—native plant life. Fauna is all of the animal life of any particular region or time. The flora of Malaysia is estimated to contain around 12,500 species of flowering plants and more than 1,100 species of ferns and fern allies.
