    1. pasture = vegetation feature with cover managed by grazing by the landowner or by agreement with the landowner: not grazed as a common/public area. Not usually cut for fodder every season of every year (>60% of annual vegetation removal by livestock, not fodder harvest).
    2. permanent grass or mixed hayfield = grass or mixed non-woody vegetation in permanent hayfield cut seasonally for animal fodder (>60% of annual vegetation removal by fodder harvest, not grazing).
    3. permanent non-grass hayfield = alfalfa or other non-grass permanent hayfield cut seasonally for animal fodder (>60% of annual vegetation removal by fodder harvest, not grazing).
