Plant demography is a fundamental element of DVM (Harper, 1977). Incorporating a simple but realistic demography module is a central aim of this project. A first version of the demography module will keep track of the plant population main features, namely the plants position (coordinates of insertion point to the soil) and age. After the energy budget and dynamic allocation modules have been developed, simple demographic dynamical features will be implemented. Plants will be able to transform their reproduction biomass (RPB) into propagules, and will disperse this propagules using a kernel function around their position. Propagules able to recruit will be new plants born that will be registered in the demography module and will henceforward able to grow and compete with other persisting plants. Plant stress detected in the allocation module will be registered in the demography module, so that using simple rules plants will be set to die after a prolonged stress depending on their size (i.e., established, larger plants will be more resistant to stress).
