A graminivore is a herbivorous animal that feeds primarily on grass, [1] specifically "true" grasses, plants of the family Poaceae (also known as Graminae). Graminivory is a form of grazing . These herbivorous animals have digestive systems that are adapted to digest large amounts of cellulose , which is abundant in fibrous plant matter and ...
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
Woody plants, shrubs or trees may occur on some grasslands—forming savannas, scrubby grassland or semi-wooded grassland, such as the African savannas or the Iberian deheza. [17] As flowering plants and trees, grasses grow in great concentrations in climates where annual rainfall ranges between 500 and 900 mm (20 and 35 in). [18]
Deer mice inhabit a wide variety of plant communities including grasslands, brushy areas, woodlands, and forests. [6] In a survey of small mammals on 29 sites in subalpine forests in Colorado and Wyoming , the deer mouse had the highest frequency of occurrence; however, it was not always the most abundant small mammal.

Grazing is a method of feeding in which a herbivore feeds on low-growing plants such as grasses or other multicellular organisms, such as algae. Many species of animals can be said to be grazers, from large animals such as hippopotamuses to small aquatic snails .
It prefers open, nonforest habitats and colonizes such open areas created by fire or other clearing disturbances. Very few eastern meadow voles are found in forest or woodland areas. In newly opened areas, it is quite abundant. [31] In these new open areas, the vole quickly becomes a food source for predators. [32]
The resulting level below which few or no leaves are found is known as the browse line. [6] If over-browsing continues for too long, the ability of the ecosystem's trees to reproduce may be impaired, as young plants cannot survive long enough to grow too tall for browsers to reach. [7]
extent of tropical and subtropical grasslands, savannas, and shrublands. Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. [1] The biome is dominated by grass and/or shrubs located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes ...
