to refer to a plant that is growing far away from its species' usual range (especially north of its range) with the connotation of being a temporary population. In the context of lichens, a vagrant form or species occurs unattached to a substrate ("loose"), not necessarily outside its range. Another definition (de Lange & Molloy, 1995) defined vagrant species in New Zealand flora – although could also be applied for any given region. Their definition was, "taxa whose presence within the New Zealand botanical region is naturally transitory... those which have failed to establish themselves significantly beyond their point of introduction through reproductive failure or for quite specific ecological reasons.". One example was the presence of Atriplex cinerea in New Zealand. References Animal migration Biology terminology Ecology terminology Phytogeography
