Sarah Flack is a Vermont-based livestock grazing consultant and author who strives to improve the environment by making farms more sustainable through managed grazing. Her philosophy lies in individualization of livestock farms. Flack argues that the differentiated needs of the plants, animals and soil of each individual farm must be taken into account to create a system in which each farm will thrive on its own system rather than conforming to a more generalized system.  Flack’s advice on “grass-based livestock farming” has been found to yield healthier soil, more robust pastures, improved animal welfare and a more financially sustainable operation for the farmers.
