Resumen:
Almost 5 % of the lansdscape of Patagonia is occupied by wetlands. In the extra-andean region and the
patagonian desert, wetlands are essential for sustaining biodiversity and wildlife. Besides, North patagonian
wetlands present complex aquatic communities and provide habitat for threatened species of fishes and
amphibians. These ecosystems have complex dynamics mostly driven by climatic fluctuations which make
them vulnerable to the effect of climate change. Nowadays, the main impact on patagonian wetland is due to
land use, species introduction, and the interaction of these disturbances with climate change. In this paper we summarize geographic, geomorphological and climatic information of several wetlands located in North
Patagonia (Argentina). Besides, we present information on aquatic vegetation, fish and amphibian fauna
distributions and endemisms with the aim of emphasizing the importance of wetlands to sustain regional
biodiversity. Finally, we highlight the processes impacting wetlands at present time and point out the
importance of obtaining basic information for management and conservation strategies.
