Aldrovanda vesiculosa © Macedonian Ecological Society

The IPAMed project keeps surprising its volunteers! This summer during one of the monitoring sessions at Prespa Lake IPA, volunteers of the Macedonian Ecological Society have found a rare carnivorous plant species Aldrovanda vesiculosa (waterwheel plant) that has not been sighted in this locality for over 20 years.

Indeed, this plant species has not been recorded in this IPA since 1996! Moreover, Prespa Lake IPA is the only locality in Macedonia where this plant was registered. According to the IUCN Red List this species is in the “Endangered” category. The waterwheel plant is threatened primarily by urban and commercial development, agriculture, aquaculture, natural systems modification and pollution.

Additionally, although its effects on natural populations are still unknown, it is believed that illegal trade also threatens A. vesiculosa. Habitat degradation is common throughout the species’ natural range, and very few sites, including those within conservation reserves, remain pristine. As the true extent of the species’ decline has become clearer, legislative protection has been provided in virtually all countries of its distribution.

Another sighting during this field work season with Salvinia natans in Dojran Lake, also a rare species which was not sighted in this region for the past few years. Finally, this valuable information was shared among all botanists in Macedonia and with the IPAMed project partners.
