Other biodiversity: Restore habitat along watercourses
A replicated site comparison in 1990–1995 in restored riparian forests along the Sacramento River, California, USA, found that some species survived after planting, as part of riparian restoration, but others did not. Plants: Box elder Acer negundo had 75–100% survival after two years (planted in five sites). Oregon ash Fraxinus latifolia had 0% survival in two of three sites but had 100% survival in one of three sites. Western sycamore Platanus racemosa had 53–100% survival in four of five sites and 0% in one of five sites. Fremont’s cotton wood Populus fremontii had 14–66% survival in three of four sites and 0% in one of four sites. Valley oak Quercus labata had 18–100% survival (planted in five sites). Californian Rose Rosa californica had 21–100% survival (planted in three sites). Sandbar willow Salix exigua had 5–88% survival (planted in two sites). Goodding’s willow Salix gooddingii had 17–94% survival (planted in two sites). Arroyo willow Salix lasiolepis had 26–100% survival (planted in four sites). Blue elderberry Sambucus mexicana had 8–68% survival (planted in five sites). Methods: Sites were on flood plains and were ≥200 ha. Seven sites were selected, with varying planting dates: Lohman (1994), Princeton (1992), River (1990), Sam (1991), Vista 1 (1992), Vista 2 (1993), and Vista 3 (1994). All sites had previously been cleared of vegetation. All species were collected from natural stands. Plants were protected by sleeves (35 cm height). Sites were irrigated and weeds were controlled through monthly spraying. Survival and height were measured in 405 m2 plots (the number of plots varied to cover 5–10% of each site). Planting rows were sampled in Lohman and Vista 3 plots. Plants were sampled at the end of each growing season.
