  abstract = {{T}heories to explain the success of alien species often assume that they are inherently different from native species. {A}lthough there is an increasing body of evidence showing that alien plants tend to dominate in highly human-modified environments, the underlying reasons why widespread natives might differ in their habitat distribution have rarely been addressed. {W}e used species distribution models to quantify the dominant environmental axes shaping the habitat of 95 widespread native and alien herbaceous species in a highly modified grassland-dominated landscape in {N}ew {Z}ealand. {F}or each species, support vector machines were used to determine 1) the environmental variables that most strongly determined a species' distribution; 2) the affinity towards a particular position along environmental axes; and 3) tolerance to environmental variation. {T}hese three measures were compared among native perennials (n = 31), alien perennials (30) and alien annuals (34). {I}ndependent of their origin, species' distributions were defined by similar environmental variables. {N}evertheless, native and alien species occupied different regions of the dominant environmental axes. {P}erennial natives occupied regions associated with lower human disturbance, while perennial aliens were associated with habitats that had been modified by vegetation clearance, pasture development and livestock grazing. {A}nnual aliens differed from perennials and were associated with both semi-natural and more intensively managed vegetation. {N}o evidence was found that aliens had broader environmental tolerances than natives that might facilitate invasion into a wider range of environments. {T}hus, widespread native and alien species differ in the degree to which environmental factors shape their distribution as a result of anthropogenic perturbations to which they respond differently as well as the introduction of functional groups that are capable of exploiting novel environments.},
