Abstract
Studies on the population dynamics of E. odoratum with particular respect to recruitment, mortality, population flux and reproductive efficiency in successional plant communities following slash and burn agriculture (jhum) are reported. The recruitment and mortality patterns of individuals in 1-, 3-, 5-, 10- and 20-yr-old fallows showed that the seedling population experienced more severe mortality in older fallows than in newer fallows. No recruitment occurred in 10- and 20-yr-old fallows. The mortality of adult shoots was greatest in a 5-yr-old fallow. The changes in population size and reproductive output are discussed in the light of changing ecological conditions and the implications of the results are discussed in relation to the jhum cycle.
