  • PF: for the habitat types that can have a non-priority as well as a priority form (6210, 7130, 9430) enter "X" in the column PF to indicate the priority form.
  • NP: in case that a habitat type no longer exists in the site enter: x (optional)
  • Cover: decimal values can be entered
  • Caves: for habitat types 8310, 8330 (caves) enter the number of caves if estimated surface is not available.
  • 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)

  • 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

Der Gersdorfer Altarm liegt im Bereich des Ennstales in der Nähe von Gröbming. Das obere und mittlere Ennstal erhielt seine heutige Ausprägung nach der letzten Eiszeit nach dem Rückzug der Eismassen, die den gesamten Talboden bedeckten. Die Enns floss in diesem Abschnitt mit einem stark gewundenen Lauf, der im vorigen Jahrhundert im Zuge von Regulierungsmaßnahmen gestreckt wurde. Der Gersdorfer Altarm befindet sich im Bereich einer alten Flußschlinge, wobei das Gelände heute größtenteils bewaldet ist.

4.2 Quality and importance

Das Naturschutzgebiet liegt zw. den Ortschaften Öblarn und Stein an der Enns. Der Altarm hat die Form eines breit gezogenen "V", seine beiden Enden grenzen an den Ennslauf. Der flußaufwärts gelegene Ast stellt mit seinem Altholz- und Artenreichtum eine Besonderheit für diesen Talabschnitt dar. Der flußabwärts gelegene Ast zeigt hingegen mit Ausnahme eines naturnahen Stillgewässerbereiches eine starke anthropogene Beeinflussung (Fichtenaufforstung, Freizeitaktivitäten). Die angrenzenden Bereiche werden von landwirtschaftlichen Nutzflächen (Äcker, Mähwiesen, Weiden) eingenommen. Die rechte Teilfläche des Altarmes wird vom Moarbach durchflossen, der hier zu einigen Fischteichen aufgestaut wurde.
