  • Type: p = permanent, r = reproducing, c = concentration, w = wintering (for plant and non-migratory species use permanent)
  • Unit: i = individuals, p = pairs or other units according to the Standard list of population units and codes in accordance with Article 12 and 17 reporting (see reference portal)
  • 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

Ansa occidentale del Lago di Caldonazzo (Valsugana), con un vasto canneto; nello specchio d'acqua è presente qualche gruppo di ninfea gialla. La vegetazione delle rive è formata in prevalenza da prati umidi e ontanete a ontano nero. Sono presenti habitat di particolare interesse non compresi nell'all.I della direttiva 92/43/CEE, in particolare: Phragmition (canneti) (30%).

4.2 Quality and importance

Lembo di vegetazione lacustre, in particolare canneto, in un'ansa di lago eutrofico, a cui fa da cornice un'ontaneta, che però in parte è stata drenata. Il sito è inoltre di rilevante importanza per la nidificazione, la sosta e/o lo svernamento di specie di uccelli protette o in forte regresso, e/o a distribuzione localizzata sulle Alpi. Presenza storica di invertebrati dell'allegato II indicatori di zone umide integre, in forte declino. Presenza di invertebrati dell'allegato II che indicano buona naturalità delle acque correnti.
