A phenomenological model for species spreading which incorporates the Allee effect, a species maximum attainable growth rate, collective dispersal rate and dispersal adaptability is presented. This builds on a wellestablished reactiondiffusion model for spatial spreading of invading organisms. The model is phrased in terms of the “hostility" (which quantifies the Allee threshold in relation to environmental sustainability) and dispersal adaptability (which measures how a species is able to adapt its migratory response to environmental conditions). The species invadingretreating speed and the sharpness of the invading boundary are explicitly characterised in terms of the fundamental parameters, and analysed in detail.
