الوصف: | We investigated the short‐term effects on stream now, habitat, water temperature, periphyton biomass, and macroinvertebrate communities of applying integrated catchment management (ICM) to improve the poor economic and environmental performance of a hill farm used for sheep and cattle grazing. Stream responses to a range of changes in land use and riparian management were compared at four reaches in sub‐catchments within a pastoral hill farm area and nearby pasture and native forest reference reaches over 6 years before and 6 years after ICM implementation. At the whole catchment scale, annual runoff from the pasture treatment catchment before ICM was 7% higher than from the native forest reference catchment, and 7‐day low‐flow was 11% lower, but runoff and low now both declined by c. 6%/yr following afforestation (mainly Pinus radiata) of 62% of the pasture catchment. At sub‐catchment level, pine afforestation with 10 m wide riparian setbacks (site A) was associated with declining channel width,... |
