The Plowprint report by WWF International tracks the gross conversion of intact grasslands to cropland in the US and Canada from 2008/2009 to 2015. Unlike net conversion studies, the Plowprint counts land as converted even if it later reverts to grass, arguing that the initial plow-up causes significant, long-term ecological loss. The analysis uses federal satellite-derived data to identify conversion hotspots and emphasizes the loss of ecosystem services such as carbon sequestration and water filtration. While noting that nearly half of the Plowprint area had reverted to perennial cover by 2015, WWF maintains that such restoration may not fully recover biological diversity or soil capacity. The document also outlines WWF's broader efforts to reduce grassland and forest conversion globally, specifically targeting soy, beef, and palm oil supply chains in Latin America and Southeast Asia.
