Abstract Impact of fire on the population dynamics of sclerophyll shrubs. - A comparison of contrasting reproductive strategies of Banksia
species by a simulation model.
In a fire prone environment the ability to store seeds in the plant canopy (serotiny) and resprouting after the fire from the root stocks are important attributes. Population dynamics was modelled for two species with contrasting life history strategies Banksia hookeriana, a nonsprouter and ( Banksia attenuata, a resprouter) in sclerophyll vegetation in Australia. The model simulated the impact of varying fire regimes on reproductive rates. It takes the seed production, seed storage and seedling recruitment pattern into ac· count as well as different weather conditions. This enables the identification of different fire regimes for population maintainance and variables under the greatest selection pressure. The key attribute for the resprouter was the probability of fire survival and for the nonsprouter the time to the onset of seed production if fires are frequent. The model is a tool for identifying suitable management procedures and defining conditions under which plant attributes like serotiny are adaptive.
