Lantana Presentation
... Lantana threatens natural habitats and native flora and fauna. As the density of Lantana increases in a forested area, the species richness decreases. The soil has a lower capacity to absorb water in dense stands of lantana than in grass cover, increasing run-off and therefore soil erosion. The p ...

Herbivore
_grazing_-_20050809.jpg?width=300)
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material.
