Mallard Egg Research Testing Potential Chemical Contraceptives Designed to Manage Overabundant Canada Goose Populations. National Wildlife Research Center. Fort Collins, Colorado

In her Managing Eden series, Joann Brennan grappled with the question of how we sustain wildness in a human world. Here, Brennan captured the work of scientists attempting to control Canada goose populations. Canada geese have become a threat to public health in suburban areas where green spaces and artificial waterways offer ideal habitats. Brennan’s image considers the necessity of human intervention to maintain the balance between human needs and those of avian populations.
