Mortality of vertebrates in irrigation canals in an area of west-central Spain

García, P. 


Mortality patterns of vertebrates in irrigation canals have been poorly studied despite their potential impact on wildlife. Concrete irrigation canals in a cropland area in west-central Spain were monitored over 13 months to assess their impact on small fauna. A total of 134 vertebrates were found dead. Most were amphibians (86.46%) or mammals (20.90%), though fishes, reptiles and a bird were also recorded. Mortality peaked in autumn months. Corrective measurements are needed to reduce this cause of non-natural mortality.
