Abstract Details

2007, Master of Science, Miami University, Botany.
Long-term demographic studies of plant species subjected to harvest for non-timber forest products can potentially be used to derive methods to rapidly assess harvest sustainability. Here I develop a rapid assessment protocol for Chamaedorea radicalis, a palm in northeastern Mexico, the leaves of which are harvested for use in the international cut-greens industry. I developed a multiple regression model relating the finite rate of population growth (lambda) to vegetative, reproductive and population-level variables from a five-year demographic study across leaf harvest treatments in the El Cielo Biosphere Reserve, Mexico. The strongest predictors of lambda were the proportion of seedlings in a population and the total adult fecundity. However, the application of the model to 21 sampled populations throughout El Cielo generated estimates of lambda with prediction intervals bracketing the net replacement rate of lambda=1. Practical implementation of this protocol is thus limited by the imprecision of the estimates of lambda.
