In France, several thousand communities, companies and individuals have already chosen to maintain their green spaces or variety of wild habitats, in an ecological way, by promoting alternative solution and using semi-feral breeds of grazing animals, like in France, with the Ouessant sheep (a Breton breed that nearly died out in recent years). It grazes the grass conscientiously, to the great displeasure of lawn mowers or brush cutters. This is eco-grazing. By opting for eco-grazing, these companies or individuals realize, on average, eco-grazing costs 30% less than conventional methods. Beyond the savings, the sheep bring life and nice company in the countryside. 2 sheep are required to take care of  2000 m², where fences, shelter and water point are installed, for their well-being. My photographic project shows, through my aerial pictures, the use of eco-grazing with these little sheep, above the salt marshes of Guérande. Abandoned for several decades, the practice is gradually returning with many advantages: no noise, no transport of material, no labor, easy access to inaccessible areas, ecological benefit and several hundred thousand liters of gasoline saved each year, thanks to the eco-grazing.  Beyond that, eco-grazing preserves the environment: - Less transport of material, no fuel, therefore less greenhouse gasses- The presence of sheep promotes biodiversity. No pesticides or fertilizers are used Sheep improve the living environment: - Their presence contributes to a soothing environment and promotes social bond- The introduction of animals makes the landscaping more lively and user-friendly By opting for eco-grazing, we are committed to the environment, maintenance and animal biodiversity. In addition to important ecological and economic benefits, companies participate in the conservation of a species. The Ouessant sheep, the smallest in the world, has long been shelved, since it is not raised for meat. There were only 486 animals left in 1977, compared to a few thousand today. The sheep are only the beginning. In France, they are now carrying out some 50 eco-grazing experiments, with goats from Lorraine, cows from the Scottish Highlands and even ponies. As we return to this time-honored practice, long abandoned in favor of herbicides and mechanical mowing, partnerships with local farmers, nonprofits and eco-grazing specialists have more and more success. I strongly do believe that eco-grazing and biodiversity are the answers to how to manage our natural environment and to maintain genetic diversity.
