The Ripple Effect of Geese on Golf Courses and Parks

The Canada goose has become a common sight in many urban and suburban green spaces, from ponds and lakes to golf courses and public parks.

While their distinctive V-shaped flying formation and honking calls evoke natural wildness, geese can cause significant problems when residing in recreational and public areas for human use and enjoyment. Their grazing, droppings, and aggressive behavior on carefully manicured golf courses create nuisances for players and extra work for groundskeepers. In parks, goose droppings and over-grazing make spaces unpleasant for visitors and raise public health concerns. However, the impact of geese extends beyond damage to turf and nuisance to park-goers. Their presence and activities in these spaces can have rippling effects on surrounding residential and commercial areas, other wildlife, and the local environment and economy. Finding solutions to humanely and effectively manage geese populations requires understanding their complex interconnections with recreational spaces, public health, ecological balance, tourism, and more.

Canada geese thrive in urban and suburban environments because of ample water sources, plentiful mowed grass for grazing, and lack of natural predators. Their populations have exploded in recent decades, bringing more of these birds into shared spaces with humans. While appreciated as part of nature, overabundant groups of resident geese crossing paths with human activity in parks and recreational areas often create problems. Achieving sustainable coexistence requires innovations in goose management and a holistic view of their complex roles across human landscapes.

The Impact on Golf Courses

A. Damage to the Course:

Geese can wreak havoc on golf course turf and landscaping when they reside. As grazing birds, they mow down the grass, damaging the carefully manicured greens, fairways, and tee boxes. This leaves unsightly bare patches and uneven turf, creating headaches for groundskeepers tasked with repairing the damage. Geese have robust digestive systems and graze intensively, so the grass does not have a chance to regrow before they return to graze again. Their grazing reduces the density and quality of the turfgrass, requiring re-seeding or re-sodding of damaged areas. While golf courses expect normal wear and tear, the focused grazing of geese can create localized devastation.

The costs of constantly re-sodding areas to maintain golfing standards get expensive for the clubs. Grazing on and around greens creates uneven, bumpy areas that affect the roll and playability of the turf, which is frustrating for golfers who expect smooth greens. Bare patches and divots caused by geese also become tripping hazards. The aesthetics of the course can decline, making the course less appealing to golfers who expect and pay for nicely kept greens and fairways when they play a round of golf.

B. Disruption to Play:

In addition to damaging the physical course, the presence of geese directly disrupts and detracts from the golfing experience. Their droppings litter the course, which is unpleasant and distracting for players concentrating on their game. Stepping or landing a ball in goose droppings can ruin a shot and require time-consuming cleaning to get back in play. This slows down the pace of play. Goose droppings may also pose health hazards if contaminated with bacteria or viruses. Geese themselves can also be distracting, honking and potentially showing aggressive behavior towards people and golf carts. Their mere presence removes the sense of solitude and natural tranquility that golfers seek when playing a round. Some geese have even learned they can access food from the garbage bins around the course clubhouse and parking lot and will wander across fairways and greens to get there.

The annoyances and disruptions geese cause to players can reduce golfer satisfaction and potentially even reduce income if golfers decide to play at another course to avoid geese hassles. For a sport where concentration and ideal playing conditions are paramount, geese on the greens and fairways create significant issues.

The Impact on Parks

A. Public Nuisance:

Like golf courses, public parks aim to provide visitors with pleasant and safe recreational experiences. However, goose droppings and damaging grazing make parks messy and unpleasant spaces for public enjoyment. Goose droppings litter lawns, paths, playgrounds, and shorelines, which is particularly problematic since parks see high visitation from children, who may accidentally touch or ingest droppings. Droppings degrade water quality in park ponds and streams. The smells and sights of excessive bird droppings render parks unsanitary and unattractive to visitors. Parks with persistent goose problems may see reduced usage, a loss for the community.

Some Canadian geese can show aggressive behavior towards humans and pets who get too close, especially around nests with goslings. They may hiss, chase, or peck at passersby whom they perceive as threats. For regular park users and families, aggressive geese present safety concerns. The combined nuisance factors of goose droppings and aggression make parks with goose infestations unappealing places for public recreation and negatively impact the community’s quality of life.

B. Ecological Concerns:

While Canada geese are natural wildlife, their abundance and behavior in park ecosystems lead to ecological concerns. As grazing waterfowl, their intensive feeding behavior can destroy aquatic vegetation and reduce biodiversity in ponds and lakes. An overabundance of geese outcompetes other native species like ducks and swans for resources. Their droppings increase phosphorous and nitrogen levels in water bodies, reducing water quality. Geese may also trample and destroy shoreline plant habitats. Their presence disrupts the natural balance in park environments.

Public entities managing parks must balance their duty to provide recreation for community members with responsible stewardship of natural habitats in public green spaces. Finding solutions to reduce goose impacts while supporting healthy ecosystem diversity is an ethical imperative.

The Ripple Effect

A. Beyond the Greens and Parks:

While golf courses and public parks face the most direct nuisance and damage from goose infestations, the impact ripples outward into surrounding neighborhoods, businesses, and public areas. Geese travel between water bodies and mowed grass areas, including ponds and lawns around homes, businesses, and commercial areas adjacent to parks and courses. Their droppings thus become a problem anywhere geese wander. Increased nitrogen from droppings can contaminate stormwater and runoff, affecting local waterways well beyond the boundaries of a single park or golf course. Goose droppings may contain pathogens and parasites. A higher concentration of these where large flocks gather increases public health risks, especially for young children exposed while playing outside. Droppings on sidewalks, driveways, and parking lots are smelly nuisances for nearby homes and businesses. Some suburban communities even report geese causing damage to yards, gardens, or vehicles.

Persistent goose flocks grazing in public areas drive down aesthetics, potentially affecting property values, tourism, and public enjoyment of community green spaces. The aggregate annoyances and damage may negatively impact the economy and quality of life in the broader area.

B. Seeking Solutions:

Given the multi-faceted problems geese cause, successfully managing goose populations involves various stakeholders working collaboratively. Wildlife management authorities must develop humane and ethical strategies aligned with conservation goals for the sustainable coexistence of geese and humans. Park management faces the difficult balancing act between keeping parks pleasant for visitors, protecting goose habitat, and mitigating goose impacts on ecology and infrastructure. Golf courses aim to provide ideal playing surfaces while coexisting with native wildlife and natural areas on course boundaries.

Cooperation between agencies, environmental groups, public health officials, and private entities allows for testing multiple adaptive management strategies to determine what works best in each location. Promising methods for discouraging geese settlement include planting unpalatable vegetation, decoys, visual deterrents, stringing fences over water, using goose repellent, and training dogs to harass geese. Timed egg-oiling or egg-shaking can reduce reproduction rates. Alterations to make the habitat less hospitable may gradually convince geese to move to more suitable areas. Continued innovation and collaboration maximize the chance of win-win solutions to offset geese impacts.

Unintended Consequences

Well-meaning management strategies sometimes create unintended ecological consequences when controlling goose populations. Culling geese or removing nests reduces their numbers but disrupts family groupings, increasing stress levels and survival instinct aggression in remaining geese. Native predators like foxes and coyotes may increase attacks on other species if geese as prey decrease. Habitat alteration, like planting cattails instead of lawns along pond edges, may discourage geese but change entire ecosystems.

Chemical repellents wash into waterways, polluting and inadvertently harming fish and amphibians. Lasers or noisemakers disturb non-target species like bats and migratory birds relying on parks as stopover habitats. Even seemingly harmless strategies like egg-oiling must be conducted judiciously to avoid damaging bird reproduction in the long term. The most ethical solutions consider ecosystems holistically to avoid shifting problems elsewhere in the environment.

Coexisting with Geese

Rather than seeking to eliminate geese presence, sustainable solutions recognize the potential for responsible coexistence if impacts are minimized. Geese nesting in these areas long before human development changed landscapes. While their numbers have surged due to favorable conditions, they remain part of the natural biodiversity. A combination of public education, nesting deterrents, and habitat modification can make parks and golf courses less ideal home bases while still welcoming temporary visits.

Signs advising visitors not to feed geese may curb goose-human conflicts and supplement natural foraging. Converting mowed grass to naturalized meadow or shrub areas gives geese food alternatives and reduces open grazing lawns. Ponds could have shallow water zones with reed beds where geese can nest away from main recreation areas. Dogs or lasers strategically used when eggs are laid at nesting sites may discourage re-nesting the following year. Continual monitoring allows adaptive changes over time for sustainable cohabitation. With intelligent design and active management, geese and their human neighbors may find ways to enjoy green spaces jointly.

Conclusion

Canada geese living among humans in recreational spaces create significant nuisances, from messy droppings to turf damage. Still, the adverse effects of geese extend far beyond the golf greens and park ponds where they directly congregate, with their impacts rippling outward into the wider community, environment, economy, and public health sphere, so navigating the complex web of stakeholders, ethical responsibilities, and unintended consequences poses challenges for sustainable goose management; however, while frustrating, geese are still part of the natural world, and solutions promoting true coexistence reconcile their needs and humans’ desire for recreational spaces, thus with innovation, collaboration across groups, and adaptive stewardship of shared green spaces, we may find ways for geese and humans to interact peacefully for generations to come.
