The underlying study investigates modern pollen-vegetation relationships in the hyper arid mosaic landscapes of north-central Oman to refine the interpretation of fossil pollen records from similar environments. Fifteen sites were sampled using pollen traps or surface samples across natural mountain, mountain foothill, and anthropogenically influenced systems, including oasis environments. Qualitative vegetation surveys were conducted within a 20 m radius around each sampling site. Most of the studied sites are located within and in the immediate vicinity of the village of Al-Khashbah in north-central Oman. Further sites are located to the north and northeast in the Al-Hajar Mountains and its southern foothills.57.08586158.22066722.60957823.140222North-central OmanFederal Ministry of Education and Researchhttps://doi.org/10.13039/50110000234701UL2001CUmWeltWandel
