Table A2.5: Summary of the effects of stand structural stages on riparian functions. Riparian functions are compared to an idealized optimal condition and described as lost (L), impaired (I), enhanced (E), or not affected (N) in a given structural stage. Bolded letters show those structural stage/riparian stream class combinations where the particular riparian function is more important than in other combinations. (from Riparian Assessment and Prescription Procedures Field Guide (draft 3A, 1996).
