description

Capsule Careful management is required to maintain or create habitats with the correct proportions of rush with reeds that are preferred by this subspecies. Aims To determine the habitat requirements of Eastern Iberian (Western Iberian Reed Buntings were not included in the study) Reed Buntings Emberiza schoeniclus witherbyi, a subspecies endemic to a few marshes in France, Spain and Morocco, with a population of 254–360 breeding pairs. Methods Twenty-five wetlands in Spain were surveyed and presence/absence of Iberian Reed Buntings was deteremined together with data on 41 environmental variables. The relationships between the birds and habitat data were investigated using glm. Results Proportion of rush with reeds, proportion of reed–bulrush patches and perimeter length of rush–reed patches, were the variables that primarily explained the present distribution of Eastern Iberian Reed Buntings. Other vegetation classes traditionally associated with the presence of the Eastern Iberian Reed Buntings, such as...
