A report released Wednesday by the U.S. Geological Survey found the most commonly eaten grassland species in the United States, and the most common land animals.
A study published in the journal PLOS ONE found that the grassland animal species that eat most grass are the red-legged deer, black bear, moose, elk and pronghorn antelope.
They are also the most important grazers of plants, according to the report.
The most commonly-eaten animal is the ground squirrel.
Other common animals are moose and antelope, with the latter being the largest land animal.
The study said grassland mammals are the most likely of all mammals to eat the most grassland plants.
It said the most often eaten plant species are: cedar, birch, fir, firs, maples, oak, oak-oak, red oak, sugar cane, spruce, walnut, and ash.
Other animals that feed on grassland are rodents, rabbits, and squirrels.
Other studies have also found that some animals, including dogs, cats, goats, and cows, are more likely to feed on plants.
The report said it was possible that the number of animals that can consume grassland crops was a function of different types of grasses.
The top-ranked grassland food is the annual and perennial ryegrass, the report said.
“Ryegris, which is the most nutritious, is most frequently eaten by animals that eat other grasses,” said study author Scott K. Moulton, an associate professor of plant sciences at Oregon State University.
He said it may be the case that ryefrass is more nutritious than other types of ryewas because it has more protein and fiber.
The species with the second-highest number of grassland meals is the bramble-bark grass, which has a higher nitrogen content than other grass species, the study said.
The second-most-common grass is the gum gum-bramble, which contains more phosphorus and magnesium than other species, and which can be eaten by humans.
“In terms of the overall nutrient content of the plant, gum gum brambles are probably the most nutrient-dense,” said Moultons.
He also said it could be the most profitable of all the grasses to eat.
“We don’t know the exact number of species that can eat gum gum.
But we know that gum gum has a high nitrogen content,” he said.
Moultons said grasses in the uppermost layers of the forest have the highest nutritional value, which can help sustain the ecosystem and provide a source of food for the animals in the soil.
