We have been told the English Wildfowl Trust sites have indeed been given site-specific exemptions to the ban on zoo opening, and will be open from Wednesday 10th June. They are full zoo licence holders and full members of BIAZA. Their permission is to specifically open the 'nature reserve' part of their sites to allow public exercise, and the 'zoo part' has to remain closed. This is the definition given, with no explanation.
My memories of all the Trust centres I have visited, are that there were no such separations. Some may have natural areas attached - but their cars-parks, reception areas and the main part of their sites were a mixture of exotic spp ('zoo part') and free-loading wild birds (as in any zoo I guess?), and the two can in no-way be separated. This presumably means if you visit Wednesday onwards and see any spp not native to Britain (and therefore a zoo animal, and thus housed in the 'zoo part'), they are breaking the law.
Could anyone who visits, post what is actually in place?
