Description

Eurasian otter (Lutra lutra) occurrence in Morocco. We collected data on otter presences and absences in 270 sites distributed across 34 Moroccan river basins, visited between April 2011 and April 2013. Data collected were used to study the natural and anthropogenic factors associated with otter occurrence in Morocco. More information in: Calzada, J., Clavero, M., Delibes, M., and Fernández, N.

Sampling Methods

The survey sites were selected a priori with the goal of covering as much of the country’s river network as feasible and being at least 30 km apart to uniformly surveying the whole region.

Study Extent We collected data on otter presences and absences in 270 sites distributed across 34 Moroccan river basins, visited between April 2011 and April 2013.

Method step description:

  1. We applied the standard otter survey method, which consists in sampling up to 600 m along the river shore searching for otter signs (spraints, anal scent gland secretions and tracks). River shores were inspected by at least two experienced surveyors in each survey. A site was coded as positive, and the survey was finished, as soon as an otter sign was found, while it was considered negative when the 600 m-long transect was completed without finding any sign.
