ΑΞΙΟΛΟΓΗΣΗ ΓΙΑ ΤΟ ΚΟΚΚΙΝΟ ΒΙΒΛΙΟ
Pyrrhosoma nymphula
Αλβανία, Ελλάδα.
Στην Ελλάδα: Πελοπόννησος, Ιόνια.
P. elisabethae occurs in a small area where its habitat is under severe pressure. It is currently assessed as Vulnerable as the population size is believed to be declining, possibly at a rate of 30% over the last 10 years and this is likely to continue, but this is not certain. Currently only seven locations are known occupying less than 20 km². Extant of occurrence is less than 20,000 km².
---------
In total, six localities of P. elisabethae are known in Greece: three on the northern part of the Peloponnisos (Greece), three from Kérkira (Greece; Corfu).
Current population size is unknown.
Information on the habitat is scarce. In the mountains of the Peloponnisos the species was found at brooklets with clear, cool water and rich vegetation. In the coastal plains of Kérkira P. elisabethae was found in a ditch and in a slow flowing river.
A further decline of this species is anticipated, as it is mainly present brooks, which are under severe pressure in large parts of Greece. The species is known from only a limited number of populations from a relatively small area. Extinction of this species in parts of its already limited range is not unlikely.
