Technical Abstract: The pasture condition score system (PCS) currently is used to assess and monitor pastures in the Conservation Security Program (CSP). Information is lacking, however, on how PCS results vary within and among grazing seasons and within and among farms. We applied the PCS on five farms across the northeast in 2004 and 2005. All pastures on each farm were evaluated according to the published PCS methodology in spring, summer, and fall of each year. Vegetation was assessed in each pasture by identifying and estimating canopy cover of all species in 10 to 30 0.25 m2 quadrats on line transects. A modified Whittaker plot technique was used in selected pastures (5 to 8 on each farm) to assess plant species diversity at multiple scales. Soil in all pastures was sampled at 0-5 and 0-15 cm depths at the start of pasture monitoring. We will discuss how pasture and farm management along with environment have affected pasture condition scores during the two years.
