The demography of Balanites maughamii : an elephant-dispersed tree
… as well as top kill by fires, because they resprout vigorously in response to damage. They also produce root suckers. independently of disturbance. Vegetative reproduction buffers the populations from the infrequent recruitment of seedlings, and facilitates the maintenance of populations …

Predicting the post-fire responses of two forest tree precursors after an autumn fire in mountain fynbos
… 1) is fire survival the (ability to resprout) related to concentrations of root stored nonstructural carbohydrates (TNC) or 2) the protection afforded to epicormic buds through the thermal properties associated with bark thickness. Different sized saplings (4-40mm in basal diameter) …

Nipping the bud hypothesis : a comparison of savannah and forest tree responses to canopy scorch
… two possible mechanisms for differences in crown resprouting following canopy scorch: (1) differences in bud banks and their insulation, (2) differences in the vulnerability to disruption of the hydraulic system by heat scorch. I simulated canopy scorch using nine congeneric savanna-forest pairs …

An investigation on the potential interactions between colophospermum mopane and its neighbouring understory vegetation
… of C. mopane trees revealed that they indeed do resprout vigorously thereafter following rainfall; it was also proved that root suckering is another strategy which C. mopane trees use for survival especially after fire. Our current work also revealed that C. mopane trees produce abundant amount …

Eradication of the giant reed (arundo donax) : an evaluation of different methodologies
… to two plots. The methods chosen were: "cut, resprout and spray", "cut-stem, spray", "chip and compost", "chip and tarp", "compost" and "compost and tarp". The response variables were the "mean regrowth height", "mean circumference of stalks" and the "number of resprouted stalks". A repeated …

Causes and consequences of prolonged dormancy: Why stay belowground?
… is a stage in which mature plants fail to resprout during the growing season and instead remain alive belowground. Though it is relatively common, the causes and consequences of this intriguing stage have remained elusive. In this dissertation, I investigate the causes and consequences of …

Demography and leaf physiology of Cornus drummondii in response to disturbance in tallgrass prairie
… to spread via vegetative reproduction and resprout after fire. The demographic mechanisms that underlie shrub responses to climate history and disturbance are unknown. Here, I measured ramet demography and leaf physiology of the clonal shrub Cornus drummondii in response to disturbance at …

Long-term Fuel and Vegetation Responses to Mechanical Mastication in northern California and southern Oregon
… In this study, species with the ability to resprout tended to recover more quickly than obligate seeding species. Residual conifer saplings or trees that establish in masticated fuelbeds also recovered rapidly, reducing the efficacy of fuels treatments. Future implementation of masticated …

Long-Term Study of Prescribed Fire Effects on Stand Dynamics and Oak Regeneration Potentials in Degraded Upland Oak-Hickory Stands in Northwestern Arkansas
… greater for oak species than non-oak with, ≥ 75% resprout percentage and greater density of sprouts (15 sprouts per rootstock). Seedling densities in the dormant treatment of oaks increased two (oaks: 1,482 stems/ac; non-oak: 3,480 stems/ac) and twelve (oaks: 1,093 stems/ac: non-oak: 3,822 …
