An object-oriented spatial and temporal bayesian network for managing willows in an american heritage river catchment

Abstract

Willow encroachment into the naturally mixed landscape of vegetation types in the Upper St. Johns River Basin in Florida, USA, impacts upon biodiversity, aesthetic and recreational values. To control the ex- Tent of willows and their rate of expansion into other extant wetlands, spatial context is critical to decision making. Modelling the spread of willows requires spatially ex- plicit data on occupancy, an understanding of seed production, dispersal and how the key life-history stages respond to environmental factors and management actions. Nichol- son et al. (2012) outlined the architecture of a management tool to integrate GIS spa- Tial data, an external seed dispersal model and a state-..
