Abstract: | The hunting impact on waders in Spain was studied to test the efficiency of species protection measures. Using information on ringed bird recoveries in Spain of 28 species a hunting impact index was calculated. The results show a high hunting pressure similar to that of other groups of birds. The hunting impact on quarry species was higher than on protected species. The change of protection level in a group of species from quarry to protected species resulted in a decrease in hunting impact. A negative trend in the hunting impact was found during a 15-year period. This result could be due to under-reporting or falsification of death causes in the recovery report. However, recoveries of shot and dead birds showed a positive relationship in contrast with expected if found dead reports increased by falsification, suggesting that there has not been a falsification of the ring recovery reports. Nevertheless, in spite of the decrease in the hunting pressure when protection measures were applied, hunting impact remains very high on protected species for a long time and studies evaluating the impact of hunting on the population dynamics of waders needs further study. |
