The phrase "availability of forage" is correct and usable in written English.
It can be used in contexts related to agriculture, ecology, or animal husbandry when discussing the presence or accessibility of food sources for animals.
Example: "The availability of forage during the dry season is crucial for the survival of grazing animals."
Alternatives: "access to forage" or "forage supply".
Temporal variability in the availability of forage reduces the production and economic performance of livestock systems.
During this time, large herbivores such as elk (Cervus elaphus) experience a chronic energy deficit due to poor quality and restricted availability of forage.
Climate (e.g., winter severity) may have exacerbated such movements by reducing the availability of forage (Clutton-Brock et al. 1985, Gaillard et al. 2000, Sæther 1997).
The availability of forage resources during the dry season is often a critical factor in determining the distribution and movement of large herbivores.
The proximate causes of these observed changes remain unknown, but may reflect an upward trend in secondary productivity, and a concurrent downward trend in the availability of forage fishes, such as the preferred Arctic cod.
The goals of this study were to test the effects of early experience at grazing medusahead – an invasive unpalatable weed – and the availability of forage alternatives on intake of medusahead later in life by sheep.
This study area, Maamora, has an old-growth forest structure incorporating a broad range of size and condition of live and dead trees, favouring Great Spotted Woodpecker by providing high availability of foraging and excavating sites.
Ideally, overwash restoration will sustain the availability of foraging habitat, but future foredune modifications may be necessary to maintain or increase overwash processes and piping plover habitat in the project area.
Although habitat quality usually is understood from a multidimensional niche space approach, the availability of foraging substrates can be a suitable and more proximate index of habitat quality for species with specialized habitat requirements, like woodpeckers that feed almost exclusively on larvae of wood-boring beetles in the trunks and branches of infested trees.
The foredune unexpectedly acted as near-total barrier to both overwash and wind, and the dynamic ecosystem underwent undesirable habitat changes including conversion of early-succession beach habitat to herbaceous and shrub communities, diminishing availability of foraging habitat and thereby reducing productivity of the Federally-listed Threatened Charadrius melodus (piping plover).
Landscape variables, such as distance to nearest site with trees, percentage of landscape with trees, and availability of foraging sites for monk parakeets around the crop fields were more important than local variables in explaining monk parakeet damage to crop fields.
