Hi Clive. Is it true that a hybrid rabbit have been released. It always amazes me how few rabbits you see in Spain compared to the UK, considering they are indigenous. Or evidence droppings.
Its never good to introduce new DNA into wild populations. I am sure the domestic DNA will have little advantage in the wild – quite the opposite long term. It may in the short term help lynx potentially if they are proliferating.
Also rabbits must have been breed in the past and semi domesticated for food – or at least been breed selectively for ability to put on weight. These must have gone feral many times. Breeding of rabbits for food is not something I’ve heard of from a historical perspective in Spain but it must have been done.
