On Bangka Island, Indonesia, a replicated, controlled before-and-after trial in 1992-1995 (Passell 2000) found that bird species richness and diversity increased over time in eight 4 ha restored former strip mine sites, whilst it remained low in four 4 ha unrestored sites (13 species recorded in restored plots vs. nine in unrestored). After three years, species richness remained lower than in secondary forest (16 species), but many of the species present were forest specialists (absent from unrestored plots). Bird abundance also appeared to increase over time but this result was less certain. Black wattle Acacia mangium was planted for restoration in 1992-1994 (400 seedlings/ha) with some trees reaching 3-4 m tall by 1995.
