Lonicera maackii (Rupr.) Herder (Amur Honeysuckle) is a large deciduous shrub from China that has become invasive in many forests in eastern/central USA. It quickly out competes native plants through a variety of life history characteristics, including rapid growth, seed longevity, and early maturity. The species was removed from a section of a bottomland hardwood forest in central Ohio, and the response of understory plants, especially herbaceous species, was measured. Plots were established in the uncleared and cleared sections, and percent cover of each herbaceous understory species was estimated monthly. One season after Lonicera harvesting, no significant association was discovered between percentage of Lonicera cover and total understory species abundance. There was, however, a direct correlation between elevation and honeysuckle abundance; L. maackii abundance was negatively associated with low elevations, likely due to hydrologic factors. Plant species diversity (H') and richness (s) increased with elevation, but were lower on plots with honeysuckle removal (H’=0.86± 0.08 vs. 0.78± 0.09, and s=4.4± 0.19 vs. 4.2± 0.2 species/m2, respectively). This is despite the fact that average (± std error) light levels taken by a densiometer reading were significantly higher in the cleared (5.9±0.5) versus uncleared (3.8±0.5) sections. The proportion of rich woods species was 70% in the uncleared section and 64% in the cleared section, while meadow species was 12% in uncleared and 18% in cleared sections. Native and invasive species were found in similar proportions in the two sections. Though the removal of L. maackii altered the characteristics of the plant species assemblage, the value of this change remains questionable in the years immediately following treatment.
