"The decline in success rates is absolutely not satisfactory, because it sometimes borders on a lottery”

Well, an honest lottery would IMHO be far better. For the reasons outlined here:

Funding competition sabotages science - Impact of Social Sciences
Research funding competitions seem fair but are often flawed. Gerald Schweiger, Adrian G. Barnett and Stijn Conix argue lotteries may support better science.

Nativeness cannot be binary, if is to make sense and be practically applicable at the scale of countries.

"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.
Just out in PNAS!
We used multi-taxon data to model virtual forest landscapes.
Forest withdrawn from timber harvesting are needed in a much higher share than they currently are in Europe, and extensive forests contribute less than expected to multi-taxon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.

We followed primary succession of arbuscular mycorrhizal fungi on a man-made island, Peberholm, 2010-2016. AMF communities diversified through more and more deterministic processes. They remained less diverse than on nearby island Saltholm.
