  • Abundance categories (Cat.): C = common, R = rare, V = very rare, P = present - to fill if data are deficient (DD) or in addition to population size information
  • Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation); VP = 'Very poor' (use this category only, if not even a rough estimation of the population size can be made, in this case the fields for population size can remain empty, but the field "Abundance categories" has to be filled in)

Other Site Characteristics

La Souleuvre se situe dans un paysage très encaissé et escarpé où dominent largement les herbages et les formations boisées de pente qui constituent des "zones tampon" entre les plateaux et la rivière. Les schistes briovériens de l'amont du bassin versant laissent place, dans la partie aval, à des formations cambriennes. La nature géologique du substrat, combinée au relief accentué et à la pluviosité forte à très forte, est parfois à l'origine de crues importantes. - Intérêt piscicole directement lié à la préservation de la qualité physico-chimique des eaux, des débits naturels et de la variété des habitats aquatiques. - Phénomènes d'érosion engendrant une augmentation de la turbidité des eaux et un colmatage des fonds. - Divagation du bétail dans le lit mineur de la rivière.

4.2 Quality and importance

La Souleuvre fait partie des rivières reconnues d'importance nationale pour l'écrevisse à pieds blancs.
