Abstract
An exotic invasive species is one that occurs outside of its natural geographical limits, which adapts and reproduces, and becomes dominant and concessionaire conducted a survey of exotic invasive tree species. The highways serve as a traverse where exotic species are easily dispersed. An inventory of invasive exotic trees (Ordinance N° 125/2009 of the Environmental Institute of Paraná) was carried out at the domain band of this concessionaire, on the highways BR 277, PR 407, and PR 508. 15 species were recorded as well as 3.939 individuals. The greatest instance species were: Pinus sp., Eucalyptus sp., Psidium guajava and Musa sp. These species are located primarily near the housing; there was a correlation between species and altitude. The management and tracking for the control of these species and environmental awareness programs are necessary, avoiding the planting of new subjects by de population and the dispersion in natural places, reestablishing the typical landscape of the present ecosystems on the road.
Keywords: Floristic; tree; altitude; biodiversity.
