"Much current hybridization probably results from human disturbance of the habitat (...). Cayouette and Catling (1992, pp.371-372) note that 252 different hybrids have been reported among species in the sedge genus Carex, but add that "sedge hybrids very a great deal in practically all of their characteristics, but the one thing that they almos all have in common is disturbed site ecology. It is quite possible that sedge hybrids were formerly rare, but have increased dramatically as a consequence of disturbance resulting from human activity". Rieseberg and Gerber (1995) suggest that some hybrids between Hawaiian plants described in the survey of Ellstrand et al. (1996) may have resulted from human disturbances. This situation may be common in plants given the tendency of some botanists to collect along roadsides."
