Modelling establishment probabilities of an exotic plant, Rhododendron ponticum, invading a heterogeneous, woodland landscape using logistic regression with spatial autocorrelation

Rhododendron ponticum has become a well-established invasive species throughout the British Isles and is now considered a problematic invasive weed species. The habitat requirements for establishment, however, have only previously been described qualitatively. The aim of this study was to quantify t...

Description
Summary:Rhododendron ponticum has become a well-established invasive species throughout the British Isles and is now considered a problematic invasive weed species. The habitat requirements for establishment, however, have only previously been described qualitatively. The aim of this study was to quantify the influence of topographical and environmental characteristics on the probability of establishment of this invasive shrub in a woodland environment. A binomial generalized linear model (GLM), incorporating spatial autocorrelation, was used to model the presence/absence of R. ponticum seedlings (
