oa Madoqua - Frost damage to wild sycamore fig trees in the Namib-Naukluft Park, Namibia



Wild sycamore fiys Ficus sycomorus suffered extensive frost damage in 1989, being the first known occurrence in 25 years. Twenty-five fig trees were monitored for 21 months and the effects of frost were related to minimum temperatures in the riverbed. Sub-zero temperatures affected 20 of the trees and caused up to 90% frost damage to leaves. Foliage affected by frost remained moribund and attached to the branches for the monitoring period. Frost may limit the distribution of sycamore figs in the Namib.
