Other biodiversity: Plant hedgerows
A replicated site comparison in 2009–2010 in the Central Valley, California, USA, found more plant species in narrow compared to wide hedgerows, and higher plant cover in younger compared to older hedgerows. Implementation options: More non-native and native plant species were found in narrow compared to wide hedgerows, and higher non-native and native plant cover were found in younger compared to older hedgerows (numbers of species and amounts of cover not reported). Methods: Thirty-one hedgerows were compared (2–7 x 120–800 m, 0–15 years old). Hedgerows <3 m wide were “narrow” (16 hedgerows), and other hedgerows were “wide” (15 hedgerows). Hedgerows were planted with similar native species. Plants were sampled at the edges (outer 1 m) of narrow and wide hedgerows and in the interior (at least 2 m from the edges) of wide but not narrow hedgerows.
