Traits Associated With Local Extinctions of Native Plants in a Species‐Rich Urban Reserve
Applied Vegetation Science, Volume 28, Issue 3, July/September 2025.A comprehensive resurvey of an urban reserve in Sydney failed to redetect 29% of native vascular plant species recorded from 1976 to 1992. Compared with persistent species, locally extinct species were shorter on average and more likely to have a graminoid habit and be water‐associated.
