The Eurasian lynx has disappeared from much of its original habitat and where populations are starting to recover, conflict with people remains a major stumbling block.
Most scientific evidence points to a major decrease in smolt-to-adult survival, which occurs in the migration corridor and in ocean and estuary habitat, he said.
