Fern distribution in El Verde MRCE plots

A fern survey was done of the plots established by under MRCE funding to assess controls on primary productivity along an elevational gradient. The control plots (CP), fertilized plots (FP) and plots where only leaf litter (ll) was removed at El Verde were survey and all ferns present in the plots listed, mapped and measured in Fall of 1995, several years after the initial fertilization and leaf litter treatment had been applied. The objective was to determine the extent to which the fern flora had been affected by the treatments.
