Second-order polynomial linear regression lines generalize the relationship between estimated fuel moisture data (log₁₀ scale) and time for four species at two grassland locations in South Africa. Analysis of deviance indicated that species was a significant term in linear mixed-effect regression models for both locations (P < 0.05), but estimated 95% confidence intervals suggest that the effect is limited to Highmoor (0.11 to 0.23) and not Ukulinga (−0.03 to 0.05). Festuca costata occurred at Highmoor only. Sampling period spans end of the growing season into late winter.
