The global increase in the pet trade and ownership of birds has heightened introduction emerging invasive vertebrate species. We analyzed online databases lost, found, sighted non-native bird reports South Africa to evaluate statuses, investigate geographic patterns, assess species trends, determine factors associated with lost birds. identified a total 1467 case representing 77 across nine families from websites (n = 3) Facebook pages 13). Most were within large cities, populated provinces, including Gauteng, KwaZulu-Natal, Western Cape. Psittacidae, Psittaculidae, Cacatuidae most dominant families, African grey (Psittacus erithacus), Cockatiel (Nymphicus hollandicus), Rose-ringed parakeet (Psittacula krameri) among top reported as lost. Lower-priced commonly there was no association between species’ price likelihood being found. In addition, we found positive relationship number shops, human population size, docility.

Online resources can be effective tools for passive surveillance species, especially potentially ones.

Abstract The Kunming‐Montreal Global Biodiversity Framework (GBF) calls for a 50% reduction in rates of invasive alien species establishment by 2030. However, estimating changes introduction and is far from straightforward, particularly on national scale. Variation survey effort over time, the absence data effort, aspects invasion process itself interact ways that make rate estimates naive models trends inaccurate. To support progress toward robust global reporting against GBF invasions target, we illustrate this problem using combination simulations, scale case studies. We provide recommendations clear set steps are needed progress. These include routine collection as part surveillance monitoring protocols working closely with researchers to develop meaningful change biological invasions. Better awareness challenge investment developing approaches will be required Parties if Target 6 tracked achieved.

Abstract The ecological impact of non‐native species arises from their establishment in local assemblages. However, the rates spread new regions and determinants have not been comprehensively studied. Here, we combined global databases documenting occurrence residence birds, mammals, vascular plants at regional scales to describe how likelihood proportion assemblages relate with time levels human usage different ecosystems. Our findings reveal that generally increases time. Colonization is most rapid croplands urban areas, while it slower variable natural or semi‐natural Notably, continues rise even 200 years after introduction, especially for birds plants, other land‐use types rather than areas. on proportions significant only mammals.
