Urban Hares: How Wildlife Adapts to City LifeUrban environments are profoundly different from the grassy meadows, woodlands, and farmlands many wild species traditionally inhabit. Yet some animals — including several species of hares — have successfully moved into cities and suburbs. This article explores how hares adapt behaviorally, physiologically, and ecologically to urban life, the benefits and risks they face, their interactions with people, and what cities can do to support coexistence.
Which hares live in cities?
Not all lagomorphs behave the same. The term “hare” commonly refers to members of the genus Lepus (true hares), while rabbits (family Leporidae, genera like Oryctolagus and Sylvilagus) are often more associated with burrowing and denning. Several Lepus species, and some rabbits, are increasingly found in urban and suburban habitats worldwide:
- European hare (Lepus europaeus) — common in farmland and expanding into suburban greenspaces in Europe.
- Mountain hare (L. timidus) — occasionally found near settlements in northern regions, especially where human land use creates open areas.
- Snowshoe hare (L. americanus) — rarely urban but may appear in edge habitats.
- European rabbit (Oryctolagus cuniculus) — not a hare but often present in urban parks and greenspaces.
- Certain introduced lagomorphs (e.g., brown hares in Australia, rabbits worldwide) have established in peri-urban areas.
Why urban areas attract hares
- Food abundance: parks, gardens, golf courses, and even roadside verges provide a steady supply of grasses, herbs, ornamental plants, and discarded food.
- Reduced predators: urban landscapes often have fewer natural predators (foxes, raptors) or predators may be less effective, lowering mortality for some hares.
- Microhabitats: lawns, hedgerows, and green corridors offer shelter and movement routes.
- Warmer microclimates: buildings, paved surfaces, and human activity create heat islands that can lengthen foraging seasons, particularly in colder regions.
- Disturbance-created habitat: construction, cleared lots, and fragmented green spaces can mimic the open, early-successional habitats hares prefer.
Behavioral adaptations
- Altered activity patterns: urban hares often shift activity to more nocturnal or crepuscular times to avoid humans, traffic, and diurnal disturbance.
- Reduced wariness: in areas with frequent benign human presence, hares may tolerate closer approach, though flight responses remain when threatened.
- Use of linear features: hedgerows, fence lines, and rail corridors become movement highways connecting feeding and resting sites.
- Flexible diet: while grasses remain core, urban individuals exploit ornamental plants, vegetables, and even food waste.
Physiological and reproductive responses
- Body condition: increased food availability can improve body condition and reproductive output for some urban hares, leading to higher population densities in favorable pockets.
- Stress and disease: urban stressors (noise, pollutants) and higher population densities can increase susceptibility to disease and parasitism; however, evidence varies by species and location.
- Reproductive timing: warmer microclimates and prolonged food supply may extend breeding seasons in cities, causing changes in litter timing and frequency.
Risks and challenges in urban settings
- Vehicle collisions: roads are a major mortality source; hares crossing streets or foraging on medians face high risk.
- Predators and pets: while some predators decline, domestic dogs and feral cats can pose significant threats.
- Habitat fragmentation: small isolated green patches can limit genetic flow and increase local extinction risk.
- Disease transmission: higher densities and contact with domestic animals or contaminated environments can elevate disease spread (e.g., myxomatosis in rabbits; hares have their own vector-borne threats).
- Human conflict: garden herbivory, crop damage, and occasional aggressive interactions (rare) can lead to persecution or control measures.
Case studies and observations
- Cities in Europe such as parts of the UK and Germany report European hares using suburban parks and sports fields, especially where pesticides are low and grass management favors a mosaic of short turf and taller refuges.
- In Australia, introduced lagomorphs (rabbits and hares) exploit peri-urban fringes, complicating management due to their pest status in rural landscapes.
- North American observations note that while true hares like snowshoe and jackrabbits are less urban, rabbits (cottontails) commonly thrive in suburban gardens and parks, demonstrating convergent adaptation strategies.
Coexistence: management and design recommendations
- Create connected green networks: link parks, cemeteries, and natural areas with hedgerows and vegetated corridors to allow safe movement.
- Traffic mitigation: wildlife crossings, reduced speed zones near green spaces, and roadside planting that discourages foraging can lower road mortality.
- Habitat heterogeneity: manage public greenspaces with a mosaic of short grass for feeding and taller vegetation for cover. Avoid blanket herbicide applications.
- Community engagement: educate residents about non-lethal deterrents (fencing, planting unpalatable species), responsible pet management, and reporting injured wildlife.
- Disease monitoring: surveillance programs for disease outbreaks and responsible disposal of carcasses to reduce pathogen spread.
Research gaps and future directions
- Long-term demographic studies comparing urban and rural populations are limited for many hare species.
- Genetic studies to assess connectivity and urban-driven selection pressures could reveal rapid evolutionary responses.
- Detailed disease ecology in urban settings needs more monitoring, especially where domestic animals and wildlife interact.
- Effectiveness of specific urban planning interventions (wildlife corridors, traffic calming) on hare survival requires localized evaluation.
Conclusion
Hares that succeed in urban environments demonstrate behavioral flexibility, dietary adaptability, and the ability to exploit novel niches created by human landscapes. Cities offer both opportunities — food, shelter, milder microclimates — and hazards — roads, pets, fragmentation. Thoughtful urban design and community-informed management can reduce conflicts and support healthy urban populations, allowing these fleet-footed mammals to continue surprising residents with their quiet presence in parks, fields, and backyards.
