Sincere question, @trevorabranch.bsky.social : how do these spawning stock biomass estimates compare to estimates from the 1960s, or even earlier? This recovery is great, and clearly better than not recovering... but is this also a case of shifting baselines?

This is a "least bad" outcome of a self-inflicted problem from Duke University. Is it better than the collection being atomized and shipped all over the place? Yes. Is it a travesty that one of the world's wealthiest private Universities divested from their herbarium? Definitely yes.
