1) In any case the TAG recommendations are very hypocritical, as they actively encourage the hybridisation of, eg, giraffe and zebra subspecies, or even separate crested porcupine species (northern and southern)!QUOTE]
Hi there
I'm not sure where the porcupine hybridisation comes from. To my knoweldge there is only 1 female northern in the region, and she is a phase out (a TAG reccomendation) in favour of the southerns. The only offspring to have been bred in New Zealand are from a pair of southerns, so no hybrisation of species has happened.
