  5. Class 1 soils have slight limitations that restrict their use. Class 2 soils have moderate limitations that reduce the choice of plants or require moderate conservation practices. Class 3 soils have severe limitations that reduce the choice of plants or require special conservation practices, or both. Class 4 soils have very severe limitations that restrict the choice of plants or require very careful management, or both. Class 5 soils have little or no hazard of erosion but have other limitations, impractical to remove, that limit their use mainly to pasture, range, forestland, or wildlife food and cover. Class 8 soils and miscellaneous areas have limitations that preclude their use for commercial plant production and limit their use to recreation, wildlife, or water supply or for esthetic purposes.

  7. Two agreements on the table • Nez Perce • State Strawman for ESPA • (Eastern Snake Plain Aquifer)

  8.
