Egyptian Geese Threaten Biodiversity in France

In the summer months, Egyptian geese have become a common sight in eastern France, waddling among sunbathers on the banks of local lakes. While they may seem harmless, these birds pose significant health risks and threaten the local biodiversity by displacing native species such as ducks and swans. Originally from sub-Saharan Africa, the Egyptian geese have adapted well to their new environment, raising concerns about their impact on the ecosystem.
Recognizable by their distinctive brown eye markings, these geese have established a strong presence in the region over the past 15 years, with their numbers steadily increasing. Pascal Koensgen, a deputy mayor in Lauterbourg, noted that the geese are territorial and have become a permanent fixture in the area. Their droppings create unsanitary conditions, with reports of large flocks fouling beaches within a day, much to the dismay of holidaymakers and local campsite managers.
Historically, the population of Egyptian geese in France was minimal, with fewer than 50 recorded between 1970 and 2000. However, since 2005, their numbers have surged to around 2,000 by early 2016, particularly in northeastern regions near the Rhine and Moselle rivers. Initially introduced as ornamental birds for decorative ponds, they have since escaped captivity or migrated from neighboring countries, leading to their rapid proliferation.
The French government has recognized the Egyptian goose as an invasive species, banning their sale since 2017. Despite this, experts like Jean-Francois Maillard from France's state Biodiversity Office (OFB) believe that the measures came too late, as the geese had already established themselves in the wild. Their aggressive behavior towards native birds, including stealing nests from swans and harassing ducks, threatens the survival of local species.
Efforts to control the population have included erecting fences, using nets, and even shooting the birds, which has been authorized in several departments. In the Bas-Rhin region, hunters have killed hundreds of Egyptian geese in recent years, but experts warn that these measures are only temporary solutions. Nicolas Braconnier from the Hunters' Federation noted that while culling provides brief relief, it does not address the underlying problem of invasive species establishment.
The situation highlights a broader global issue, as the United Nations has identified thousands of alien species introduced by humans, with many classified as invasive. Experts emphasize the importance of swift action when dealing with unwanted species to prevent their spread. In the case of Egyptian geese, their adaptability to artificial lakes and vegetation makes them particularly difficult to control, raising alarms about the potential long-term consequences for France's native wildlife. As the geese continue to thrive, the challenge of preserving local biodiversity becomes increasingly urgent.
