Thanks in particular to Michele Di Musciano, Riccardo Testolin and Ale Chiarucci for stearing the boat safely ashore

The results only tell us that site selection was (a lot) better than random, not if the management of N2000 sites secured long-term persistence of biodiversity. Alas, lots of evidence suggest the opposite.

Well, I believe it’ll be more applicable than the binary concept in less studied taxa and regions, as it is less evidence demanding when it comes to questions like “how did the species arrive in the focal area” etc.

Thank you, Camilla Colding-Jørgensen for leading this important work, and to @jcsvenning.bsky.social and @r-ejrnaes.bsky.social for the collaboration, which was funded by the 15 June Foundation

Using the flora of Denmark, we show that a large proportion of species are treated as 'native' by one source and as 'non'native' by others, i.e. are of uncertain status. Using a graduated definition, most of these species end up in the 'near-native' category

Native and near-native species share most of their Pleistocene history. Are near-natives may well be our new natives under global climate change.

Men ja, egentlig er det jo logisk nok. Alligevel tror 99% af den danske befolkning (og politikere) at biodiversitetskrisen skal løses ude på markerne. Den grønne trepart bygger 100% på at gøre ingenting i de officielt, men ikke reelt, beskyttede naturområder, men i stedet lave *skovrejsning*

Nja, bare at sandsynligheden for lokal uddøen er lige så stor inden for Natura2000- og §3-beskyttede områder som udenfor. De officielt beskyttede naturområder DK melder ind til EU og CBD er streger på kort uden reel virkning for de truede arter. Læs videre her:
