Conservation
Conservation is a key component of Cosley Zoo’s mission.
We demonstrate our commitment to conservation on a daily basis by participating in environmentally friendly practices such as recycling, using a rain barrel to collect water for plants, re-purposing materials rather than buying new ones, minimizing plastic waste by providing plastic bags and straws to guests on request only, and installing energy-efficient lighting. We also participate in several large-scale conservation initiatives.

AFRICAN PENGUIN
© 2017 David Cook
Africa’s only penguin species
Once numbering in the millions, African penguin populations have plummeted to less than 42,000 individuals. Overfishing, habitat degradation, and disasters (oil spills, disease outbreak, etc.) have contributed to this significant decline. Association of Zoos & Aquariums (AZA) facilities have joined forces to help the African penguin by developing various initiatives, from improving disaster response protocols for oil spills to constructing artificial nests.
BLACK-FOOTED FERRET
One of the most endangered mammals in North America
Through the collective resources and expertise of Association of Zoos & Aquariums (AZA) accredited institutions, the Saving Animals from Extinction (SAFE) black-footed ferret program aims to repopulate the black-footed ferret, so it is no longer an endangered species. This is being accomplished through targeted conservation projects, increasing public awareness, and raising funds in support of black-footed ferret conservation.
BLANDING’S TURTLE
Illinois Endangered Reptile
Due to illegal capture, loss of habitat, predation, and vehicle and fishing accidents, this once-numerous local resident is now struggling to survive. Your donations will help Cosley Zoo and its local partners, like The Forest Preserve of DuPage County, in efforts to rear young turtles for release and improve the quality of their natural wetland habitat. Donations will fund continued research and purchase food and equipment vital to the long-term success of this project.
CONSERVATION TEAM
Cosley Zoo’s Conservation Team meets monthly to further conservation efforts within the zoo and the community. They are responsible for planning and implementing the zoo’s chapter of the FrogWatch USA citizen science program, organizing Adopt-a-Stream and other local clean-up events, maintaining the zoo’s rain barrel, and creating conservation awareness messaging on zoo grounds and social media, amongst other initiatves.
GOING GREEN IN THE GIFT SHOP
We are proud to be able to offer several eco-friendly items for purchase in the Wild Side Gift Shop! These include 4Ocean bracelets made of recovered plastic from the ocean, reusable drink cozies made from plastic water bottles, reusable metal straws, plush animals made from recycled materials, and animal figures carved from tagua nuts that look like ivory but are animal-safe.
SAFE SPECIES
In 2015, the Association of Zoos and Aquariums introduced a new initiative called AZA SAFE: Saving Animals From Extinction. The program was designed to allow the wildlife experts at AZA-accredited zoos and aquariums and their nearly 200 million yearly visitors to work together to help the world’s most vulnerable species. Since its inception, SAFE has established projects for 25 species or groups of species, and in 2019 alone contributed $230 million to conservation efforts. Cosley Zoo is proud to be a collaborator on four of the SAFE species projects.
The critically endangered vaquita is a small porpoise endemic to the Gulf of California in Mexico, and is the world’s rarest marine mammal. The illegal use of fishing equipment called gillnets, in which vaquitas can become entangled and drown, has resulted in a steep decline in the population. The goal of SAFE is to raise awareness about the threats of illegal fishing and to work with the people of the Gulf of California to create sustainable fisheries. Cosley Zoo is involved in public engagement for the project, educating the public through social media campaigns and information on zoo grounds, hosting events to raise funds, and helping to circulate petitions asking the Mexican government to heavily enforce bans on the use of gillnets.
Cedar waxwing
Birds throughout the world have been experiencing sharp population declines since the 1970s due to numerous compounding factors such as habitat loss, pesticide use, and climate change. Their roles in insect control, pollination, and seed dispersal make them vital to the ecosystems in which they live, and further losses could lead to dramatic consequences for other species, including humans. Cosley Zoo is part of this SAFE program’s Citizen Science Working Group, which has a goal of raising awareness of the current plight of songbirds and contributing to scientific research by encouraging participation in citizen science projects.
Monarchs were once a common sight throughout the country, but populations have experienced significant declines in the past twenty years. Monarch caterpillars feed exclusively on milkweed plants, meaning milkweed is crucially important monarch breeding habitat. The loss of milkweed due to herbicide use and agricultural development is one of the largest threats to monarchs. Cosley Zoo is part of this SAFE program’s group tasked with creating and protecting breeding habitat, though as the project progresses may be able to assist in other areas as well.
This program focuses on conservation efforts for a number of different turtle species, including the eastern box turtle, the spotted turtle, and the Blanding’s turtle, all of which are considered vulnerable or endangered. These turtles and many others are susceptible to human-caused mortality, such as road collisions and habitat destruction. Cosley Zoo looks forward to sharing expertise gained from nearly twenty years of head-starting and releasing Blanding’s turtle hatchlings to help other species throughout the country as well.
IN THE FIELD
BLANDING’S TURTLE HEAD START PROGRAM
Cosley Zoo is proud to partner with the Forest Preserve District of DuPage County, as well as the Peggy Notebaert Nature Museum, Brookfield Zoo, and St. Charles Park District, in this program which works to help increase the wild population of Blanding’s turtles (Emydoidea blandingii) in Illinois.
Blanding’s turtles are medium-sized semi-aquatic turtles whose distribution is concentrated around the Great Lakes. Their population has been declining in recent years due to the loss of available wetland habitat. In addition, increased pressure from predators has caused a decrease in the number of turtles surviving to sexual maturity (15-20 years of age). In 2009, Blanding’s turtles were added to the endangered species list in Illinois.
The Head Start program aims to increase the number of Blanding’s turtles surviving long enough to reproduce. The Forest Preserve District of DuPage County collects gravid (pregnant) turtles from the wild and houses them until they lay their eggs. After the eggs hatch and the young turtles are off to a good start, some of them are raised by Cosley Zoo staff for about a year. The turtles are reared at an accelerated rate, so that when they are released back into a DuPage County wetland, they are larger than a wild turtle of the same age and should be less vulnerable to predators. The young Blanding’s turtles are not on display at the zoo in order to minimize their exposure to humans, but we do have an exhibit containing adult Blanding’s turtles which can be viewed by the public seasonally, as well as a live video feed of the turtle rearing area.
Cosley Zoo participates in several conservation initiatives on an ongoing basis, including a program to save the Blanding’s turtle.

FrogWatch Cosley Zoo is a local chapter of FrogWatch USA, a citizen science program, managed by Akron Zoo, that invites individuals and families to learn about the wetlands in their communities and help conserve amphibians by reporting the calls of local frogs and toads.
FrogWatch USA volunteers play an important role in amphibian conservation. Over 2,000 amphibian species are currently threatened with extinction and many more are experiencing sharp population declines. This alarming trend may be a sign of deteriorating wetland health because amphibians can serve as indicator species.

Help Native Wildlife From Home
Endangered species are not just found in distant places – some live right here in Illinois! The following species are endangered in Illinois, but there are things you can do to make a difference! With a little effort at home, you can help protect locally endangered species, and all native Illinois species – even small actions can have a big impact!
- Short-eared owls are important predators of small rodents. These are the only Illinois owls to nest on the ground, and you can help protect them by walking your dog on a leash in nature preserves so their nests are not disturbed. They are also threatened by habitat loss, so supporting restoration of prairie habitat can bring more of these birds to Illinois.
- Reduced wetland habitat has negatively impacted the black-crowned and yellow-crowned night herons. Sign up for a wetland restoration workday and help improve the habitat for these birds.
- Snakes like the massasauga are important components of ecosystem health, helping to control rodent populations. Avoid using rodent bait at home to prevent contamination of the snake’s food source. In addition, rattlesnakes are often killed by humans who are afraid of being bitten. By learning to peacefully co-exist with snakes like the massasauga, you can help prevent their unnecessary elimination.
- The Hine’s emerald dragonfly depends on pristine wetland areas. Help protect your local water supply by minimizing the use of lawn chemicals, recycling used car oil, and properly disposing of paint and other toxic household products.
- The Karner blue butterfly serves an important role in the ecosystem by pollinating flowers. By planting a butterfly-friendly garden full of native plants at home, you can help all of Illinois’ endangered butterfly populations.
- Like all amphibians, the spotted dusky salamander can absorb water through its skin, so it needs to live in clean water to thrive. Participate in a stream clean-up and avoid polluting to help maintain clean water for all amphibians.
- The gray bat can eat nearly 3000 insects a night, including disease-carrying mosquitos, but overuse of pesticides can poison their food supply. You can help protect bats by reducing the amount of pesticides you use at home. Additionally, grey bats live in caves year-round, and are vulnerable to human disturbance, so it is important to follow rules put into place by the U.S. Fish and Wildlife Service when visiting or exploring caves.
