Conservation measures improved the status of 13 animal species worldwide in 2018, but in every 2019 assessment where a species' status changed, the species declined.
Notes on verification
Corroborated by IUCN press releases and independent Mongabay reporting confirming zero improvements among 2019 status changes; the specific '13 species' figure for 2018 traces to IUCN's own announcements and wasn't independently cross-verified beyond that primary source.
