SummaryThe Houbara Bustard is a winter visitor to the United Arab Emirates. Monitoring its population over large areas is difficult, due to the low density of the species and the nature of its habitat. We examined the possibility of using a network of desert rangers in the western region of the Abu Dhabi Emirate to monitor the population, timing of occurrence and distribution of Houbara Bustards in two consecutive winters. Houbara Bustards arrived in Abu Dhabi in September and moved inland towards the south of the country. The last birds were seen in March. Numbers ranged from 56 to 112 in 1994/1995 and 117 to 235 in 1995/1996. Houbara sightings were not evenly distributed within the region, with consistently higher numbers in sand-dune areas. This habitat is not optimal for Houbaras, where, in the past, they were less often encountered. The level of disturbance associated with more favourable habitats may be one reason why the birds are moving to more remote and inaccessible places. The use of a network of local rangers proved to be invaluable for gathering information on the low density Houbara population over a large area and was a very efficient way of monitoring the status of this endangered species.

SummaryUnited Arab Emirates is an important range country for the ‘Vulnerable’ Socotra Cormorant Phalacrocorax nigrogularis and Abu Dhabi Emirate holds most of the remaining breeding colonies. Emirate-wide monitoring of all breeding colonies was undertaken annually for 11 breeding seasons from 2006–2007 to 2016–2017 to monitor the status of breeding colonies and estimate the nesting population. Breeding was recorded in 10 colonies that were used intermittently with an average of four (± 1.3 SD) colonies active each year. The highest number of eight active colonies was recorded in 2016–2017. Establishment of two new breeding colonies on Butinah and Digala in 2016–2017 and recolonisation of three previously inactive colonies during the monitoring period emphasised the ability of the species to relocate and colonise suitable sites. Continued threats at some breeding colonies caused abandonment and subsequent relocation, resulting in a gradual shift of breeding colonies to safer areas. Presently, most of the breeding sites (62%) with an increased number of breeding birds are found in colonies with restricted access. The Emirate-wide nesting population witnessed a 10-fold increase in the last decade; after an initial decline in 2006–2007 it increased from about 5,000 pairs in 2007–2008 to nearly 52,000 nesting pairs in 2016–2017. Combined with the nesting population from the Siniya colony, the overall UAE nesting population is estimated at 60,000 to 70,000 pairs, nearly half of the global breeding population. Further augmentation of the current breeding numbers is possible if breeding colonies remain safe from human disturbance and invasive predators. For long-term conservation of Socotra Cormorant, protection of all remaining colony sites, including inactive ones, is important in addition to minimising disturbance along with widespread public awareness to change the people’s perception of the species as a competitor to commercial fisheries.

Many cities in the world define themselves as ‘smart.' Is this term appropriate for cities in the emergent Gulf region? This article investigates seven Gulf cities (Kuwait City, Manama, Doha, Abu Dhabi, Dubai, Sharjah, and Muscat) that have once grown rich due to large reserves of oil and gas. Now, with the threat of ending resources, governments focus on the development towards a knowledge society. The authors analyzed the cities in terms of their ‘smartness' or ‘informativeness' by a quantitative survey and by in-depth qualitative interviews (N = 34). Especially Doha in Qatar is well on its way towards an informational city, but also Dubai and Sharjah (both in the United Arab Emirates) make good scores.

Reintroduction of once existing red mangrove, Rhizophora mucronata trials were carried out in Abu Dhabi, United Arab Emirates. Propagules were procured from Pakistan and cultured in a greenhouse before they were planted alongside existing Avicennia marina forest in two sites of Abu Dhabi emirate, Abu Al Abyad and Ras Ghanada Islands. This study documents the present condition of the plants after 11 years of plantation. Long term survival rate was as high as 81% in Abu Al Abyad while Ras Ghanada experienced a very low survival rate at 10%, primarily due to external factors. In contrast, Ras Ghanada plants showed higher growth with the mean height stands at 2.06 m (SD ± 0.31m), while in Abu Al Abyad it is 1.53 m (SD ± 0.36 m). In Abu Al Abyad, more than one third (36.4%) of surviving plants showed reproductive phenology, whereas in Ras Ghanada it was only 10.3%, despite of greater height classes. Many Rhizophora were also noticed with well-developed stilt roots. This study showed that Rhizophora mucronata can be planted in Abu Dhabi, despite the Emirate's harsh climatic conditions.
