Highlights
Tree heath is one of the rare plant species facing a drastic population decline
Maxent performance was excellent (AUC > 0.9) in predicting the potential distribution of tree heath
The current potential area coincides with that modeled by Maxent and ArcGIS
The distribution of E. arborea was highly associated with cold temperature (i.e. high altitude) and rainfall
Under RCP8.5 in 2070, the suitable habitat range of Erica will shrink by 54%

Abstract
Tree heath (Erica arborea L.) is a rare and endangered native tree species that is facing an incessant population decline due to climatic and anthropogenic factors. The objective of this study was to analyse the impacts of future climate change on the potential distribution of the species in the alpine areas of Tigrai. A species distribution modelling using Maxent was employed to predict the potentially suitable habitat for the species under two future climatic scenarios. The model was constructed using 58 sets of presence data collected from five main forest areas of the region and 11 environmental predictors. The results revealed that altitude, precipitation in the warmest quarter, distance from the sea, aspect, precipitation in the driest quarter and precipitation in the wettest quarter were the main factors influencing the distribution of E. arborea. The distribution of E. arborea was highly associated with cold temperature (high elevation) and rainfall. E. arborea is sensitive to temperature fluctuations (bio7). The current suitable habitats of E. arborea were restricted within 2097 km2. The highly suitable habitats for future distribution were the Irob, Atsibi, Emba Alaje, Endamokhoni, Ofla and Tsegede highlands of Tigrai. Under RCP8.5 in 2070, the suitable habitat range of Erica will shrink by 54%. Therefore, in situ and ex situ conservation interventions should be introduced to save the rare species in the Tigrai highlands.
