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.

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

@hhbruun.bsky.social

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

A graduated nativeness definition for overcoming dilemmas and difficulties of vascular plant species

Nativeness cannot be binary, if is to make sense and be practically applicable at the scale of countries.
We propose a graduated definition, in which species native to neighbouring territories are considered "near-native"

Nativeness is a concept central to biodiversity conservation and invasion biology, but there are several problems related to a classic binary nativeness definition. Dilemmas arise from the dynamic na...

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:

Sustainable forest planning: Assessing biodiversity effects of Triad zoning based on empirical data and virtual landscapes | PNAS

"We show that unmanaged forests are the backbone of biodiversity conservation ... We conclude that to preserve forest biodiversity in Europe, we should increase the proportion of unmanaged forests and the amount of structures supporting biodiversity in extensively managed forests.

Forest withdrawn from timber harvesting are needed in a much higher share than they currently are in Europe, and extensive forests contribute less than expected to multi-taxon diversity.

In their Table 2, the authors claim to summarize data from our paper and 14 others. But the figures do not come from our study of plants, insects and fungi (how could they?). The authors surely haven’t read, nor understood, our study. But much worse, their data must be considered *fabricated*

Disturbing citation
In 2022, we published a study on *consumers*, i.e. animals and fungi that consume biomass produced by other organisms, e.g. plants.
Now, our paper has been cited in what claims to be a metaanalysis of "Consumer Satisfaction in Live Streaming E-commerce". Far out!

A Willow Warbler (Phylloscopus trochilus) perched on a lichen-covered branch. The small songbird has olive-brown upperparts, pale cream underparts, and a subtle yellow eyestripe. The delicate bird, weighing just a few grammes, is photographed in sharp detail against a soft, blurred background of foliage. Despite its diminutive size, this species undertakes remarkable long-distance migrations between Europe and Africa, carrying microscopic botanical evidence of its journey in its feathers.
