In 2003, Dullinger et al. examined patterns of shrub invasion into high mountain grasslands of the Northern Calcareous (Limestone) Alps in Austria. Dullinger and his colleagues wished to determine whether Pinus mugo, a species of invasive conifer, showed a preference for invading some grassland habitats over others. The data provided give the number of Pinus mugo observed in each of six grassland types studied by the investigators. Assume that the area covered by each of the six habitats studied are approximately equal. Grassland Type Pinusmugo. Count
Calamagrostis varia grassland 7
Carex ferruginea grassland 9
Nardus stricta pasture 2
Deschampsia cespitosa pasture 11
Hdictotrichon parlatorei grassland 2
