ABSTRACT

This study analyzed plant species composition and vegetation changes over time acrossnine wildlife crossing structures (WCSs). A total of 166 taxa were identified, comprising 56 families,128 genera, 155 species, 3 subspecies, 6 varieties, 1 forma and 1 hybrid, with Asteraceae, Poaceae, andFabaceae showing high occurrence frequency. Analysis of dormancy form revealed a higherproportion of perennial plants, particularly hemicryptophytes and woody species. A total of 24naturalized plant species were recorded, and species such as Erigeron annuus (L.) Pers., Oenotherabiennis L., and Robinia pseudoacacia L. were frequently observed. When comparing early-, middle-, andlate-stage WCSs, early and middle stages were dominated by herbaceous species adapted to dry anddisturbed habitats, while late stage WCSs showed an increased presence of forest edge species. A stabilization trend dominated by native species was observed along natural succession. Actualurbanization index decreased after 10 years of corridor establishment, indicating gradual stabilizationof habitat conditions.
