As a geographer/geomorphologist with interest in nature (karst) protection, I'm dealing with one Natura 2000 site in Croatia under heavy pollution pressure. It is a sinking river in contact karst area exposed to pollution from nearby dump site and sewerage - consequences: pollution of river (destruction of water fauna), its ponor and underground stream possibly up to the distant karst springs. One of the basic problems is in bad delineation of borders not including larger catchment area (small city, suburban area with important percentage of arable land - a lot of anthropogenic pressure) but only small part of river bed. So it is completely inefficient because it does not prevent or reduce the pressure on the protected water habitat of interest. Second problem is that most of Natura 2000 sites in Croatia are poorly managed or not managed at all (no management plans), with badly determined borders/areas drawn without enough scientific fundamentals so their efficiency is questionable in many cases.
My question rised from topic asked 5 years ago: https://www.researchgate.net/post/How_well_is_Natura_2000_protecting_European_biodiversity2
I'm searching for any updates on this topic - newer articles with examples. I'm interested in various habitats, not only karst and water, but all good examples of bad decisions in delineating Natura sites and repercussions to habitats, flora & fauna.
Maybe we can start some collaboration in this topic...
Thank you.
