Recommended restoration strategy for straight reaches, converting incised channel to natural alternate barsequence with two stage channel. Note: Alternate bar morphology is idealized; designed conditions should be morevariable. Suggested dimensions are listed in Section 4.3.4 of the report.• revegetate restored floodplains and terraces inthe sand-bedded zone completely (as opposed topatches) using conventional farming techniques.Vegetation should be planted instaggered rows or in pseudo-sine waves,mimicking the natural spatial variability andachieving complete vegetation coverage.Complete planting coverage will become densegallery forests (much like Figure 2-17 and 2-27) and will provide interior forest habitatessential to wildlife (e.g., yellow billed cuckoo);• revegetate by series rather than species toprovide both the canopy species and understoryspecies;• actively remove confining riparian berms aspart of restoration projects in areas wherevegetative encroachment has occurred into theactive channel;• protect all restoration and preservation sitesfrom future disturbance through conservationeasements or land purchases.153
