The Canada goose, known for its confident walk, loud honking, and impressive flight, has become a common sight in ponds and urban parks across France. However, this bird is not native to the region. The species was introduced to Europe as early as the 17th century, mainly in Great Britain, where it was kept in private collections and aviaries. Its presence in France began in the 1960s, when a small number of birds either escaped or were intentionally released. These early individuals found favorable conditions in natural water bodies, parks, and open spaces, leading to a population boom between the 1960s and 1970s. Another major growth period occurred between 2008 and 2016, partly because there are few natural predators in the region to control their numbers. In 2010, the Canada goose was officially classified as an invasive exotic species in France, meaning it poses a risk to the local environment. This classification was reinforced in 2016 with stricter management measures. As a result, a national plan was introduced to control the population. This includes capturing the birds, destroying nests, using scaring techniques to deter them, and banning feeding. These actions aim to reduce existing populations and prevent the species from spreading to areas where it is not yet present. The impact of the Canada goose on the environment is considerable. The large amount of droppings they produce can lead to water pollution and eutrophication, a process in which excess nutrients cause algae to grow rapidly, often at the expense of other aquatic life. Their herbivorous diet also causes damage to agricultural crops near water sources, as well as the grass on golf courses and recreational areas. Furthermore, the constant movement of large groups of geese can weaken the banks of waterways, increasing the risk of erosion and subsidence. Ecologically, the presence of Canada geese disrupts the local balance by competing with native birds for nesting sites and territory. To address the growing problem, public authorities have implemented regulatory actions. A ministerial decree from 2010 prohibits the introduction of Canada geese into the natural environment. This was strengthened in 2016, allowing for more aggressive management strategies. Current methods include mowing grass in a way that deters geese, banning feeding in public areas, and using scaring techniques in sensitive locations. If these preventive measures fail, the destruction of nests or even individual geese is allowed, but only under a specific legal framework to ensure compliance with environmental and animal welfare regulations.
