Other biodiversity: Restore habitat along watercourses
A replicated site comparison in 1989–2001 in 23 riparian forest sites along the Sacramento River, California, USA, found that vegetation cover, native species cover, and the number of native species was lower in restored sites, compared to remnant sites. Plants: In the understorey, the cover of total and native vegetation was lower in restored sites, compared to remnant sites (total: 40–50% vs 73%; native: 2–10% vs 51%), as was the number of native species (3–5 vs 12), but the cover and number of exotic species was no different (15–17 vs 10 species; 40–42% vs 21% cover). In the overstorey, total cover was lower in remnant sites (0–29% vs 82%). Methods: Native riparian tree and shrub species were planted (520–1,300 tree/ha) on former farmland along 150 km of the Sacramento River (15 sites restored in 1989–1996; three sites restored in 2000). Plants were surveyed in quadrats (1 x 1 m) in spring 2001 at restored sites and five remnant sites.
