1. The following changes will occur for all alternatives. It may be a slow process in the uplands, depending upon rainfall, soils, topography, etc. For Alt 1, the changes will occur faster in the Bishop and Redding Resource Areas, and slower in the Susanville area due to the nature of the RAC proposed guidelines for those areas.

2. For Alt 2, rates of change will be the same as Alt 1 due to using essentially the same guidelines.

3. For Alt 3, rates of change will be slower due to a lack of utilization guidelines.

4. For Alt 4, rates of change will be the fastest due to the rapid implementation.

5. The following changes will occur for all alternatives. It will be a faster process than the uplands, due to more water and better soils. For Alt 1, the changes will occur faster in the Bishop and Redding Resource Areas, and slower in the Susanville area due to the nature of the guidelines for those areas.

6. With improvements in vegetation in riparian areas, all functions will improve. Especially, proper functioning riparian zones act like a sponge, holding the water longer, and releasing it slowly throughout the year. The following changes will occur for all alternatives. For Alt 1, the changes will occur faster in the Bishop and Redding Resource Areas, and slower in the Susanville area due to the nature of the guidelines for those areas.
