Propagules reach remote areas sooner, however their infrequency, combined with the blocks of unfavorable coniferous habitat in the north mean that spread is little affected. The main differences is that the agricultural areas in northeastern Maine could now be reached (compared to the full model) from established populations further south, however even this occurs rarely (not at all during this sample of 100 model runs). This dispersal neighborhood could have been used in our model equally as well as the 51 x 51 grid cell neighborhood that we chose.
