  • Guiding Principles for Bringing Moisture Back to the Land 1.Protect and expand moisture storing areas of the landscape (enhance the Sweet Spots). 2.Stabilize active erosion and prevent further degradation. 3.Restore dispersed flow and increase infiltration at every opportunity. 4.Cultivate restorative plant communities and build biologically active soils. 5.Create site-specific solutions using natural forms and processes.
