I am delighted to hear about the area in my hon. Friend’s constituency, and I think it important to continue with the theme of ensuring how we can look after the hedgehog.
I was also told that elastic bands, which postmen discard when delivering letters, are also detrimental to hedgehog survivals. There is no robust evidence on this point, but it is one of many concerns that have been raised with me about the pitfalls that hedgehogs must dodge.
Not only do we need hedgehog-friendly gardens, but I also want my hon. Friends and the Government to give local authorities advice on ensuring that hedgehogs do not get caught up in bonfires. Last week, we celebrated bonfire night and I raised my concerns about hedgehogs making nests in the bonfires before they were set alight. One of my hon. Friends suggested that this might be a Catholic plot to ensure that attention was taken away from Guy Fawkes—but I rather dismissed that.
Although it is not thought that badgers are the principal culprit in the demise of hedgehogs, they cannot be totally blame free. In a major DEFRA study, which assessed the ecological consequences of badger removal during the randomised badger culling trial lasting from 1998 to 2006, it was found that removing badgers from a habitat had a number of consequences for other species. The report said that hedgehogs rarely encountered badgers in rural sites, but were found relatively frequently in amenity areas.
Population density increased by over 100% over the course of the randomised badger culling trial in amenity sites in proactive cull areas, while declining slightly in no-cull control sites. No similar increases were detected in rural sites. The report also found that there is strong evidence that badger predation restricts hedgehog populations and that amenity areas in villages act as a spatial refuge for hedgehogs.
In 2011, a further report on the state of British hedgehogs concluded that, while badgers are a natural predator of hedgehogs, where there are good foraging opportunities for worms and beetles, badgers and hedgehogs can coexist. However, when there is no safe refuge, and badgers and hedgehogs compete for these scarce resources, hedgehogs may be in serious trouble.
A more recent study in 2014 found that in areas of preferred habitat, counts did not change where there was no badger culling. An analysis of the original badger culling experiments, published in April 2014, shows that while at some sites hedgehog numbers did increase, following a reduction in the number of badgers, it was thought that some of the sample sizes might have been too small.
I must point out that there have been widespread calls for more research into the effects of the badger, and I welcome this. As I explained earlier, badgers are not the sole cause of the decline in the hedgehog population, but I believe that there is a real danger that if more research is not put into the badger cull, hedgehog numbers will continue to decline. I hope that the Minister will take note of that.
There is a pressing need to support hedgehogs in urban areas. It is very important to focus on the barriers created by walls and impermeable garden fences and the consequent fragmentation of the hedgehog population. The House may like to know that I am pressing my
fellow neighbours at the Royal Naval hospital in Plymouth to ensure that we can create a hedgehog-friendly community and increase the number of hedgehogs in this part of my inner-city constituency.
