Scientists surveyed six species of Pyrenaria, a little-known flowering tree genus in Northeast India, and found that most are struggling to regenerate due to logging, mining, and agricultural encroachment. One endemic species, found only near Cherrapunji, has less than 1,633 square kilometers of suitable habitat left, making it a priority for urgent conservation.
Of 167 individual Pyrenaria trees recorded, only 47 were seedlings and 21 saplings versus 99 adults, indicating severely limited natural regeneration.
The endemic species P. cherrapunjeana has a predicted suitable habitat of just 1,633 km², making it among the most range-restricted plants in the study.
MaxEnt habitat models achieved high accuracy (AUC 0.850-0.999), with mean diurnal temperature range, precipitation, and elevation as the top drivers of species distribution.
