Effects of liming on Oxalis acetosella and Lycopodium lucidulum in a northern hardwood forest.
Lime has been applied to lakes and catchment areas in order to counteract the effects of acidification. Results are reported from laboratory and field (Woods Lake catchment basin, Adirondack Park, New York) studies of growth and tissue nutrient responses of the herbaceous species Oxalis acetosella and Lycopodium lucidulum to applications of lime (96-98% CaCO3). Growth was stimulated in O. acetosella and reduced in L. lucidulum, and nutrient compositions of shoots and roots were altered in both species. Liming of catchments could result in reduced abundance of L. lucidulum.
