Assessment of the causes and extent of damage to trees of Olea europaea subsp. cuspidata (Wall. and G.Don) Cif. (wild olive) in the mountains of Oman
Thuraiya Al Jabri, Alastair Culham, Richard H. Ellis

TL;DR
Wild olive trees in Oman's mountains are suffering from damage due to human activity, drought, and over-browsing, with some areas showing high levels of harm.
Contribution
This study quantifies the extent of damage to wild olive trees in Oman and identifies key threats to their survival.
Findings
29% of wild olive trees experienced high damage levels (45% to 64%).
Wild olive trees in the Western Hajar and Dhofar Mountains showed the greatest damage.
No natural regeneration of wild olive was detected across all eight locations.
Abstract
Olea europaea subsp. cuspidata (Wall. and G.Don) Cif. (wild olive) is one of the key woody species in the mountain habitats of Oman. Wild olive trees are scattered, isolated, and at risk from several threats including climate change, urbanization, browsing, human activity, and the introduction of non-native species. One hundred and eighty-four trees from eight locations in three mountain ranges (Eastern Hajar, Western Hajar, and Dhofar) in Oman were assessed. The extent of damage to trees caused by browsing, drought (dead branches), and human activity (cutting and burning) was scored between 10 June and 5 July 2020. Most olive trees in these mountain ranges exhibited moderate damage, ranging from 21% to 45%, while 29% of wild olive trees experienced high levels of damage, ranging from 45% to 64%. Wild olive trees in the Western Hajar Mountains and Dhofar Mountains showed the greatest…
