Browsing (herbivory)

Browsing is a type of herbivory in which a herbivore (or, more accurately, a browser) feeds on leaves, soft shoots, or fruits of high-growing, generally woody, plants such as shrubs. This is contrasted with grazing, usually associated with animals feeding on grass or other low vegetation.

Overview

Browsing is a behaviour associated with animals that feed on leaves, tender shoots, bark, and other plant material that is above ground level. This behaviour is most commonly seen in ungulates, which are large, hoofed mammals. Browsing is an important aspect of the feeding ecology of many species, including deer, giraffe, and goat.

Browsing vs Grazing

While the terms browsing and grazing are often used interchangeably, they refer to two distinct types of feeding behaviour. Grazing typically refers to the consumption of grasses and other low-lying vegetation, while browsing refers to the consumption of leaves, shoots, and other high-growing vegetation. Some animals, such as goats and deer, are known as mixed feeders because they engage in both browsing and grazing.

Impact on Ecosystem

Browsing can have a significant impact on the ecosystem. Over-browsing by herbivores can lead to deforestation, particularly in areas where these animals are not naturally regulated by predators. On the other hand, browsing can also have positive effects on the ecosystem. For example, it can help to maintain biodiversity by preventing any one plant species from dominating the landscape.
