Jones slams Parks Canada for allowing the horses to remain, accusing the agency of using weasel words such as 'wild' and 'naturalized' to disguise the invasive, damaging nature of the herd. 'Parks Canada is completely out to lunch in relation to the science,' he said, noting that some bird species are directly threatened by the heavy hooves and foraging of the horses.
Today, Sable Island is a new National Park Reserve. It is managed by Parks Canada, whose National Parks Act includes the statement that, 'Maintenance or restoration of ecological integrity, through the protection of natural resources and natural processes, shall be the first priority of the Minister when considering all aspects of the management of parks.' Because ecological integrity is degraded by any populous alien species, the horses should be regarded as a threat to that particular mandate.
