Most ranchers and range management professionals are aware that forage plants decline in nutritional value as they advance in maturity. The relationship of nutritional value and stage of maturity has been reviewed for range plants by Kilcher (1981) and for forage crops by Fick et al. (1994). During the first Range Nutrition Short Course conducted by University of California Cooperative Extension in 1993 it became apparent that many ranchers understood this relationship, but most were unable to estimate crude protein (CP) accurately from stage of maturity. Most range management professionals are also uncertain of approximate CP levels at different stages of maturity. The information in this publication can be used by range managers to estimate CP for some common California foothill range plants, if they know the stage of maturity.
