  1. Other biodiversity: Exclude grazers

    A site comparison in 2014 in an alpine meadow in southern California, USA, found more and larger willow Salix sp. trees in a plot from which cattle were excluded, compared to a grazed area. Plants: Streamside vegetation within a plot from which cattle were excluded had more willows than the surrounding grazed area (980 trees in 1,200 m vs 75 in 900 m) and had a lower cover of sedges Carex sp. (data not reported). Willows within the ungrazed plot were larger than those in the grazed area (average height: 48 vs 25 cm; maximum height: 300 vs 170 cm). Methods: Cattle were excluded from a 1,200 m section of stream in 1991 but were allowed to graze on the remaining 900 m. Vegetation within 2 m of the stream was surveyed in 2014.
