Remotely sensed indices unreliable in informing elephant forage: findings of Dr. TNC VIdya & team

Grass abundance, which indicates elephant fodder, tends to be low in locations with dense canopy cover

A field study by researchers from Bengaluru shows that a popularly used index that remotely estimates density of vegetation does not yield a reliable estimate of food abundance for elephants in tropical forests. In fact, researchers show that this index has a negative correlation with graminoids (grassy food – grasses, sedges and rushes – preferentially consumed by elephants) in tropical forests.
