The annual demographic fates of the main perennial grass species of the Lamto humid savanna (Côte d'Ivoire) under the influence of four fire treatments between 2015 to 2019

These data represent the demographic fates of the four dominant perennial grass species of the Lamto savanna (Andropogon canaliculatus, Andropogon schirensis, Hyparrhenia diplandra and Loudetia simplex) based on annual changes in tussock size and mortality under the influence of four fire treatments. These treatments are Early fire (applied in November), Middle fire (the mid-dry-season fire, in January), Late fire (in March) and No fire (unburnt plots).

They have been applied to these species on 12 plots (3 per treatment) since 2013 until today. Each individual was marked as soon as it appeared on the plot after application of all the treatments and monitored until its disappearance, between 2015 and 2019. During these annual surveys, we measured the circumference of all individuals, which allowed to classify them into five circumference classes (Class 1: 3–10 cm, Class 2: 10–20 cm, Class 3: 20–35 cm, Class 4 : 35–50 cm and Class 5: >50 cm) and study the impact of the fire treatments on the demography of these species using matrix models.
