Just some thoughts about the 'off-topic' Pheasant-questions
which ones are truly able to persist long-term without hunting management?
To ask: Which one of lots of other farmland breeding birds in most part of Europe are able to persist long-term (without nature conservation efforts)?
As for Germany the breeding atlas of Schleswig-Holstein explained that the county-populations had a light increase in the period 2005-09 in comparison to the period of 1984-94. Mass-releases of Pheasants had stopped in the late 1970s. In the same time the number of hunted Pheasants had an equal decline. If one consider the estimated population of about 11.500 "breeding pairs" (2005-09; I suppose that means the estimated number of territorial males...) and consider the hunting stretch of about 10.000 birds/year, that seems to be an high number of killed birds. But there were still releases of Pheasants to the wild of unknown numbers after the hunting saison. Considering the massive change in agriculture with intensification and dramatic loss of suitable habitats for all farmland breeding birds (also the Pheasant), I come to my personal conclusion, that they are doing quiet fine in Schleswig-Holstein as breeding birds, especially in comparion to other species like Grey Partridge, Skylark and so on... So therefore, if all influences were band (hunting, release, land change and so on), I suppose the Pheasant would have no problem to survive as a C1-candidate in Schleswig-Holstein.
One more thought to the subject: In the given situation we are, and if e.g. Gray Partridge, Skylark, Black-tailed Godwit, Lapwing... with there massive decline in recent years - despite all the nature conservation efforts - were not native, noone would come to the idea, that these species might fulfill the C1-criterias nowadays.
Best regards!
PS: Glad to read the three Swedes have at last found there way to Germany ;-) Althougt the Albatross as "german entry in the big year" would be much more glamorous, than (of all) these domestic geese... a shame!
