  abstract = {{S}avanna trees often display significant hollows due to the combined action of fire and termites ({N}'{D}ri et al., {J} {T}rop {E}col 27:269-278, 2011). {O}bservations have shown that internal cavities caused by termites in tree stems often result in external hollows under annual fire regimes, and it is quite possible that such hollows/fire interaction may increase the probability of trunk or big branch breakage and/or tree mortality. {A} study of individual tree and branch mortality as a function of prior termite and fire damage was undertaken in a {W}est {A}frican savanna ({L}amto, {C}te d'{I}voire) where most of the trees naturally have hollows in their stems due to termite and fire interaction. {O}ur goal was to examine the dynamics of hollowing and to determine whether hollowing significantly affected tree mortality. {B}ranch and whole plant mortality were quantified for dominant tree species according to their initial hollow state and height. {F}our different responses were obtained depending on tree species: (1) mortality increased with cavity severity and tree size ({P}iliostigma thonningii), (2) mortality depended on tree size only ({B}ridelia ferruginea), (3) no mortality even after being hollowed by termites and externally damaged by fire ({C}rossopteryx febrifuga, the species with the highest proportion of individuals with hollows yet the greatest background survival time, 14 +/- {A} 2 years) and (4) high mortality, but few hollow trees suggesting a weak resistance to hollowing ({C}ussonia arborea which was insensitive to all the factors examined in this study). {F}or species resistant to hollowing, tree mortality was rare; alternatively, for species prone to hollowing, whole trees died quickly and before the most severe hollow classes could be observed. {L}ong-term demographic data yielded population-level mortality estimates of adult trees at least four times lower in fire-exclusion zones than that in fire-prone areas. {B}ecause hollow dynamics interact with fire in affecting adult mortality of some dominant tree species, fire management is important for a sustainable woody component of these savannas.},
