Urban Wildlife Biodiversity Monitoring
Monitoring stations from the city to the suburbs will help scientists chronicle the wildlife of the Chicago region.
Cities can be hostile places for wildlife, with threats coming from habitat destruction, roads and traffic, humans, pets, and large numbers of invasive species. However, with proper management, urban areas can house a number of important wildlife species, including carnivores, small mammals, birds, insects, reptiles, and amphibians.
To assess the biodiversity of the greater Chicagoland area, Lincoln Park Zoo’s Urban Wildlife Institute has established monitoring stations within city parks, forest preserves, golf courses, and cemeteries across a four-county area, including downtown Chicago and its suburbs. Motion-activated field cameras are deployed four times per year at more than 100 sites to determine which species are present and to assess spatial and long-term patterns in wildlife communities.
Adding New Dimensions
To date, the motion-activated field cameras have mainly detected medium- to large-sized mammals, as well as some birds. In 2012, researchers began opportunistically sampling arthropods (insects, spiders, etc.) found within the metal security cases that house the cameras. Habitat type, urbanization, tree species, and season all may have an effect on which arthropod species occupy these security cases.
To further understanding of wildlife communities, Urban Wildlife Institute researchers have also set up a number of acoustic monitors at a subset of biodiversity monitoring project sites. Acoustic monitors allow researchers to identify bird species at a site based on their calls. These sampling methods will help researchers at the Urban Wildlife Institute generate a greater understanding of how land-use and habitat fragmentation can affect wildlife populations.
Valuable Knowledge for Conservation
Knowing where Chicago’s urban wildlife will help support conservation efforts. This knowledge will pave the way for future studies on the behavior and ecology of specific urban species, helping stakeholders to better manage wildlife conflict.
