Taxonomic Notes
Until recently, other taxa were included within the concept of B. maritimus; this obscures the limits of its distribution and may obscure population trends.
Taxon distribution as listed in assessment
Within the UAE, Jongbloed et al. (2003) reported this species from a small number of scattered locations in the eastern UAE (Abu Dhabi, Al Ain, Ras al Khaimah). Survey data from the Sharjah Seedbank & Herbarium show additional scattered records (Hatta, coastal Ras al-Khaimah and eastern Sharjah). Feulner (2016) reported this species from Wadi Wurayah National Park (pools at the base of the Wadi Wurayah waterfall and along the wadi above), an area that is intensively used by tourists; the origin of the species here requires confirmation. The species has an enormous global distribution in temperate and subtropical regions (Board of Trustees, RBG Kew 2018).

Assessment rationale/justification
Within the UAE, this species is reported from a small number of scattered locations in the eastern UAE (Abu Dhabi, Al Ain, Ras al Khaimah, Sharjah, Hajar Mountains). However, the identification of B. maritimus and B. glaucus is difficult, and B. maritimus is easily confused with other wetland sedges found in the UAE. As a result, it is not certain whether the species found in the UAE is B. maritimus or B. glaucus. In addition to this uncertainty, the coastal wetlands habitats of these Bolboschoenus species have undergone significant change due to development, water abstraction, climate change and pollution. Further research is required to confirm the presence and distribution of this species in the UAE and, therefore, it is considered Data Deficient.
