🌿 Refugia for a rare tree in a changing world
Herbert et al. modeled disease risk, soil waterlogging, and road access to identify high-priority refugia for Syzygium maire, a threatened wetland tree in Aotearoa New Zealand under threat from myrtle rust.
🔍 Using integrated species distribution models and high-resolution hydrological data, they found that just 1–52 km² of habitat across the Wellington region may be suitable, accessible, and relatively low-risk. But that’s not enough-active restoration and management are essential to save this species.
🌧️ Disease, drainage, and development have reduced habitat-but people can help restore it.
🌱 The study highlights how local knowledge, access, and conservation action must align to protect species like S. maire from extinction.
