“…As with other man-made wetlands (Tourenq et al 2001;Maeda 2001;Múrias et al 2002;Elphick and Oring 2003;Ma et al 2004;Paracuellos and Telleria 2004;Santoul et al 2004), these ponds were exploited all year long by several waterbird species and provided them with refuge, food and/or breeding sites.…”

“…In general, artificial wetlands hold less abundant populations than natural wetlands (e.g. Tourenq et al 2001;Ma et al 2004), but these man-made wetlands may be important in some situations and for certain species (Froneman et al 2001;Elphick and Oring 2003). For example, irrigation ponds hold larger populations of Blackwinged Stilt, Little Grebe and Common Shelduck than the natural wetlands at the area (Martí and Del Moral 2004).…”

“…Therefore, irrigation ponds should be included in the official waterbird censuses, which are conducted every year in order to obtain more precise knowledge of the real population in the study area (Martí anddel Moral 2003, 2004). Moreover, the importance of ponds, like other artificial wetlands (Maeda 2001;Tourenq et al 2001;Múrias et al 2002;McKinstry and Anderson 2002;Elphick and Oring 2003;Paracuellos and Telleria 2004;Ma et al 2004;Santoul et al 2004;Okes et al 2008, Rendon et al 2008, increases as a result of the degradation of natural ones. In our case, the value of ponds for waterbirds conservation is higher in the breeding season, as a consequence of the characteristics of the climate in the zone.…”

“…Many authors have already studied the relative importance of artificial wetlands, and most have found that they can provide suitable habitats for waterbirds (Tourenq et al 2001;McKinstry and Anderson 2002;Paracuellos and Telleria 2004;Santoul et al 2004;Okes et al 2008, Rendon et al 2008. Salt marshes, aquaculture fish ponds, mine impoundments, gravel pits, rice fields or irrigation ponds are able to provide alternative or substitute habitats for waterbirds communities as well as for amphibians (Knutson et al 2004;Julian et al 2006) plants or invertebrates (Nicolet et al 2004;Taft and Haig 2005;Abellán et al 2006).…”

Agricultural ponds as alternative habitat for waterbirds: spatial and temporal patterns of abundance and management strategies

The progressive lost of natural wetlands as a consequence of human activities has lead to the use of new habitats by the species linked to water presence. In Southeast Spain, thousands of irrigation ponds have been lately constructed to store water for agriculture and are used by waterbirds as an alternative habitat. For this study, breeding and wintering waterbirds were counted in a subset of irrigation ponds between 2002 and 2007. Breeding communities were more abundant than wintering communities, but they presented a similar richness and diversity. The ponds were selected by waterbirds according to their characteristics, and breeding communities were more selective than wintering communities. Our results enhance the importance of pond size (area), connectivity (distance to the nearest wetland) and habitat quality (resource offer and construction material) in the pond selection process. The presence and design of these impoundments could be playing a crucial role for some waterbirds species. Therefore, the long-term information provided here can be useful for establishing management strategies for these artificial wetlands.

“…The climatic conditions, the use of different rice varieties over somewhat different soils, the differences in weed species, the fact that the landscape is more fragmented in the Camargue, and that the waterfowl use the ricefields mainly as nocturnal foraging grounds may all potentially lead to different conclusions. Additionally, previous studies may have underestimated total waterfowl use of ricefields since surveys were made during the day-time (e.g., Tourenq et al 2001 for Europe; Elphick and Oring 2003 for the US). In particular, we aimed at quantifying (1) the trampling effect of ducks on the density of standing stalks and; (2) the foraging effect of ducks on seed abundance and species richness, considering both rice leftovers and weeds.…”

Winter-flooding of ricefields provides foraging habitat to waterfowl, which in return may bring agronomic benefits to farmers. Our study experimentally tested the effect of mallards (Anas platyrhynchos) on the standing stalks and weed seed bank in the Camargue (France), both of which present major challenges for farmers. Three duck densities were tested: (D1) 5 ducks ha -1 (historical nocturnal density), (D2) 23 ducks ha -1 (present nocturnal density), and (D3) 300 ducks ha -1 (Asian rice-duck farming density). The ducks reduced the stalks significantly: -27 % (D1), -52 % (D2), and -91 % (D3). Conversely, they decreased the number of seeds by only 3 % (D3) and the seed mass by about 21 % (D1 and D3), which was not significant. Besides they had no effect on seed species richness. This study clearly demonstrates that the winter-flooding effect on straw decomposition can be enhanced by waterfowl foraging, hence showing an agronomic benefit from ducks to farmers. However, there was no clear effect in terms of seed bank reduction.

Biodiversity provides numerous essential services to humans, as has become increasingly apparent in recent decades. Anthropogenic effects on land use represent principal threats to biodiversity conservation (Wilson et al., 2016). Humans depend on agriculture, but agricultural land use dramatically changes surface cover and soil characteristics while some species coexist well with agriculture, in general, intensive agriculture is a principal driver of biodiversity loss (
