Other biodiversity: Restore habitat along watercourses
A replicated site comparison in 2010–2012 in riparian forests along the Sacramento River, California, USA, found similar numbers of birds and mammals in restored and remnant forests. Birds and Mammals: Overall, similar numbers of species were found in restored or remnant forests (4–5 vs 4). More species were found in restored forests, compared to remnant forests, in the wet seasons (4–5 vs 2), but not in the dry seasons (3–5 vs 3). More predator species were found in young restored forests, compared to remnant forests (1.9 times as many species as in remnant forests). Most animals were black-tailed deer Odocoileus hemionus columbianus (66% of all observations) or wild turkeys Meleagris gallopavo (21%). Most predators were raccoons Procyon lotor (8% of all observations), coyotes Canis latrans (4%), or bobcats Felis rufus (1%). Methods: All sites were part of The Nature Conservancy’s Sacramento River Project. Camera traps were set along a 100 km section of the river in restored forests (young: restored in 2003–2007, five sites; old: restored in 1991–2000, six sites) or remnant forests (five sites). Sites were 5.34 km apart, on average. Camera traps (2.1 m height) were placed on trees at each site, near animal signs (tracks, scat, or scratch marks). Cameras were visited every 1–1.5 months.
