An artificial lakes system intended for human recreation supports a vital breeding population of Red-wattled Lapwing in the Arabian Desert

[摘要] Various animal species worldwide use artificial environments for reproduction, a suitable alternative to dwindling native habitats. An artificial lake system established in the core zone of the Al Marmoom Desert Conservation Reserve, Dubai, United Arab Emirates, primarily intended for recreational purposes, assists wildlife to cope with water shortages and the extreme hot climate of the Arabian Desert. This area potentially opens up conflicts between recreational use and wildlife welfare. The Red-wattled Lapwing (Vanellus indicus aigneri) is a spreading Asian shorebird tightly linked to water resources and tolerant of human disturbance. We analyzed the habitat use and reproductive success of this species, following 361 nests and 373 chicks in 2018 and 2019 to reveal the breeding potential of the Reserve. The occurrence of lapwings dropped sharply at a distance of 500 m from the lakes, regardless of vegetation cover and desert type. In addition, nest site choice strongly reflected the proximity of water within the core lakes area. The Lapwings bred preferentially on islands built in the centers of the lakes, where they started breeding earlier in the season. They had a lower nest predation rate on islands than on the surrounding mainland, but the chicks grew slightly more slowly on islands, probably due to lower food availability. However, survival of island and mainland chicks was similar. We conclude that the shallow shores of lakes with islands make the area suitable for breeding of the Lapwing in the Arabian desert, despite extensive recreational use and constant human disturbance. This study shows an example of combining appropriate landscape design with benefits for humans and current support for wildlife conservation.
