The strictly carnivorous Pallid and Montagu's Harriers are confirmed to be crucial secondary seed dispersers in India, rescuing viable seeds from the digestive tracts of their prey and playing an important role in maintaining the biodiversity of threatened grassland ecosystems.

Tropical savannas, replete with large expanses of grasslands, are often misclassified as wastelands.

Scientists used mathematical models and satellite data to understand how seed dispersal from forest trees helps in maintaining the savanna–forest boundaries.
