Not only do arctic grasslands support higher biodiversity and abundance, there is building evidence that the grazing, compaction and disturbance effects of these larger herbivores enables the deeper freezing of the permafrost during the winter months.

Enhancing grassland production through active management, burning, and grazing rotations may become important parts of resilience strategies in the future.

What is the role of large grazing animals in maintaining a healthy mosaic of forest and grasslands?

Large herds of grazing animals evolved to roam around natural grasslands, eating the grasses and being chased by large predators.

All cattle graze freely on natural grasslands and are totally grass fed, with no supplement feed.

The Great Lakes website states, «Ranchers in Argentina and Brazil have traditionally raised cattle in herds that graze freely on the natural grasslands.

In realistic terms, any major effort to supply additional plant protein for human consumption in the U.S. would require dismantling the nation's agricultural system, since most of American agriculture is directly or indirectly involved in producing livestock either through direct grazing on grasslands or by growing feed on cultivated land.

For millennia they have lived on the steppes, grazing their livestock on the grasslands.

In places with extensive grasslands, like in the United States, Brazil, Argentina, and Australia, people gravitated toward grazing livestock.

In Savory's defense, much of his argument for his grazing method is specifically that it promotes retention of seasonal moisture in soils in arid grasslands.

It seems that the most we could hope to accomplish with grazing management is to return grasslands to their equilibrium state, with carbon levels at preindustrial levels in both the vegetation and the soil organic matter.

Consequently, soil water availability represents a much greater limitation to maximum carbon storage in global grasslands than does grazing management.

How grasslands sequester carbon: grasses tend to keep root systems in proportion with top growth, so when livestock graze on high grasses then that land is allowed to rest, the roots slough off the excess growth and their carbon becomes available to microbes as food, polymerizing it into humus.

They also ignored the processes involved, including, but not limited to, the differences in properties of grazed lands compared to woodlands, the effect of the ocean and other sequestration sinks, and the fact the while undergoing deterioration and desertification, poorly managed grasslands are an emission source instead of a sequestration sink due to land use changes.

The grasslands around the lake evolved with natural grazing, some of that is good for the land.

Four additional carbon offset methodologies are currently in ACR's approval process for publication in 2013 including California and Mid-South modules for Emission Reductions in Rice Production, a modular approach to Grazing Land and Livestock Management in beef and dairy production, a methodology for Avoided Conversion of Grasslands and Shrublands to commodity crop production, and a methodology for quantifying emissions reductions from Carbon Capture and Storage in Oil and Gas Reservoirs.

Siberia being seasonally cold with wholly Mammoths grazing on the grasslands.

Drawdown's yield model calculates total annual global supply of crops and livestock products based on their area of adoption in each of the three scenarios, and global yield impacts of each solution (including both gains due to increased productivity per hectare and losses due to reduction of productive area due to adoption of non-agricultural solutions, e.g., loss of grazing area due to afforestation of grasslands).

Conservationists and ranchers will work together to use cattle grazing, prairie dogs and reseeding to restore the grasslands.

Conversion of desert and grassland to cropland, grazing, fire suppression, introduction of invasive species, disturbances leading to soil erosion and blowing dust, and the development of urban areas have all likely had impacts on regional climate.

For example, in the Arctic, where about 500 gigatons of carbon is stored in permafrost, large grazing mammals like caribou and muskoxen can help maintain the grasslands that have a high albedo and thus reflect more solar energy.

The global area of grasslands, which is easily double the world cropland area and which is usually too steeply sloping or too arid to plow, can contribute to the food supply only if it is used for grazing to produce meat, milk, and cheese.

Saving the Grasslands with grazing animals by Alan Savory (well worth watching): https://www.youtube.com/watch?v=vpTHi7O66pI

By mimicking the natural symbiosis between plants and animals, holistic grazing would, Savory argues, encourage the regrowth of carbon - sequestering grasslands.

Grazing ruminant animals with their emission products have always been part of healthy grasslands.

Mobs of grazing ruminants have been roaming the grasslands since cave - man days.
