Site selection by geese in a suburban landscape

Area of Science:

• Urban ecology
• Wildlife management
• Landscape architecture

Background:

• Geese are common urban herbivores causing human-wildlife conflicts.
• Lethal control is a common but questionable strategy for goose population management.
• Human-altered habitats often contribute to increased goose populations.

Purpose of the Study:

• To investigate how suburban park landscaping influences goose presence and human-goose conflict.
• To identify specific landscape features that can be modified to reduce goose attraction.

Main Methods:

• Five-year observational study in a Belgian botanic garden and data from Flanders.
• Analysis of landscape features including islands, water proximity, flight barriers, and area size.
• Focus on Egyptian geese and various anserine geese species.

Main Results:

• Lakes with islands attracted over twice as many anserine geese.
• Flight barriers effectively deterred geese from feeding areas.
• Smaller, tree-surrounded grazing areas were less attractive to geese.

Conclusions:

• Landscape design can effectively reduce goose numbers and human-goose conflict.
• Modifications require human compromise on desired park aesthetics.
• This approach offers a sustainable alternative to lethal control methods.
