  1. Mechanically/manually remove invasive plants

    A replicated, controlled study in 2001-2004 in temperate broadleaf forest in Ohio, USA (Swab, Zang & Mitsch 2008) found no effect of removal of the invasive shrub Amur honeysuckle Lonicera maackii after hydrologic restoration on understory plant species richness and diversity. Numbers of species (cleared: 4; control: 4/m2) and diversity (Shannon's index cleared: 0.8; control: 0.9) were similar between treatments. Data was collected in 2004 in 29 cleared (removal of Amur honeysuckle shrubs during 2001–2003 and herbicide treatment to the remaining stumps) and 31 control (uncleared) plots (1 m2).  A hydrologic restoration project had been carried out at the site in 2000-2001.
