Re. Larsen et al., VIEWPOINT - LIVESTOCK INFLUENCES ON RIPARIAN ZONES AND FISH HABITAT -LITERATURE CLASSIFICATION, Journal of range management, 51(6), 1998, pp. 661-664
A key was used to classify articles about livestock influences on ripa
rian zones and fish habitat into 3 classes: papers that contained orig
inal data, those that were commentary, and reports about methodology s
uch as classification systems, policies, and monitoring criteria. Four
hundred and twenty-eight of the total articles were directly related
to grazing impacts on riparian zones and fish habitat, Only 89 of thes
e grazing impact articles were classified as experimental, where treat
ments were replicated and results were statistically valid. This analy
sis revealed several limitations of riparian grazing studies that incl
uded: (1) inadequate description of grazing management practices or tr
eatments, (2) weak study designs, and (3) lack of pre-treatment data.
More long-term, replicated treatment studies are needed in the future.
