CAIP quizzed 100 members of the public on their awareness of wildlife poisoning.
The research reveals that though members of the public come across dead animals, few take any action.
More than half would report dead wildlife if they suspected illegal activity, however, and deaths of birds of prey, deer and badgers are most likely to be reported.
?We have to question the relevance of some of this research and whether it will help or hinder the fight against pesticide poisoning,? the Countryside Alliance?s Tim Bonner told Shooting Times.
He added: ?Wild animals do die in the countryside from a range of causes and it is important that people do not start to think that every carcase is the victim of illegal killing. Having said that, it is important that real cases of poisoning are reported and we applaud CAIP?s work in tackling illegal poisoning.?
Responding to the shooting community?s criticism of the research, a CAIP spokesperson told Shooting Times: ?Many animals die of natural causes or from road traffic collisions, but regrettably a number of deaths are caused by the abuse or misuse of pesticides. However, what is clear from the research is the need to improve people?s awareness of the Wildlife Incident Investigation Scheme (WIIS), the signs of pesticide poisoning and the correct reporting procedure.?
The research also showed those questioned are most likely to report a suspicious wildlife death to the RSPCA or the police but a third did not know to which organisation they should report their concerns.
BASC?s Tom Blades said the survey highlights the need for greater public awareness of pesticide poisoning: ?To find that only 2% of those questioned were aware of the WIIS is disturbing. BASC supports the efforts of the WIIS and would welcome an increased understanding of its work for the ultimate benefit of the countryside.?
The research revealed some interesting statistics, which showed support for legal pesticide use.
A spokesman for the National Gamekeepers? Organisation said: ?All wildlife dies at some point, so it is hardly surprising that the countryside contains a lot of dead animals. But only a tiny minority will be there as a result of illegal killing, so the public?s non-reaction is probably the right one.?
He added: ?The CAIP generally does good work and it is right it should publicise numbers to report the misuse of pesticides. As an aside, we were interested to see yet more market research coming up with 70% support for legal predator control. That is the good news behind this story.?
