The Swiss Valley Nature Preserve and Nature Center serves as the headquarters for much of the environmental education programming carried out by Conservation Board Staff. The Nature Center has been a popular feature in Northeast Iowa since 1973. The dairy barn turned Nature Center was totally renovated in 2003. Dubuque County Conservation Board added 10,000 square feet of space for educational programs and first-class interpretive displays.

Our professional staff presents programs to over 18,000 students and public each year. We believe strongly in hands-on learning; instead of talking about forests and succession we visit the forest, instead of pictures of frogs we experience the live animal. Through these hands-on methods program participants gain a greater understanding of the importance of conservation and stewardship.

Please inform us if you plan on eating lunch at the center. Dubuque County Conservation Board is a Green Vision Education partner; we strongly encourage ‘waste free’ lunches. The waste free lunch is an opportunity for the students to monitor their choices in packaging, for example: bring Tupperware versus plastic baggies. Please bring a plastic bag to carry waste back to school with you.


Most programs take place outdoors. If severe weather threatens, staff has alternative indoor activities for your program topic. Only in cases of extreme weather will we cancel a program.

Elementary/Middle School Program Subjects


Orphaned wildlife is rarely truly orphaned. Usually mother is hidden nearby watching. Adult mammals have strong odors that are easily detected by predators. Young mammals are naturally protected by not having strong odors that attract predators. Wild mothers will not stay in a nest unless they are actually nursing their offspring. If you discover a nest of young wildlife, leave it alone. They do not need to be “rescued”.

Baby rabbits spend many hours alone in their fur-lined nest with the mother rabbit secretly visiting only to nurse them. She is rarely seen. Rabbit nests that are discovered should be left alone and pets should be kept away from the site. If tiny rabbits handled by humans, the mother rabbit will still return and care for them. Her instinct to care for her young is greater than her fear of human scent. Leave them in the nest or at the nest site if the nest have been destroyed. The mother will move them to a new nest. Be patient. She may wait for darkness to hide her activities.

Deer hide fawns in tall grasses or woodland plants. Fawns may appear to be abandoned but do not be fooled. The doe is nearby watching and she will return.  Never remove a fawn from where it is found.

Baby birds are frequently found on the ground, especially as they leave the nest for the first time, an act called fledging. It is natural for fledglings to spend some days on the ground while learning to fly and be independent. The parents feed and care for the young during this critical period. It is important to keep cats and dogs away from the site. A young bird found on the ground can be placed in a nearby bush or tree for safety. If you place it back in the nest, it will only leave again. Birds that are fledglings will be covered with feathers.

Storms often knock baby birds from nests before the birds are ready to fledge. The birds will not be fully feathered. Place the bird back in the nest if you can. Birds have very little sense of smell and parent bird will not detect that a human has handled their young. Parents will return to care for the young. Do not take the bird into your house. If the parents return and cannot find their young, they will assume a predator destroyed them and not return to that nesting site. It is best to let nature take its course. Injured creatures are a link in the natural food chain.

All wild baby birds, mammals and reptiles are difficult to care for. Wild animals and birds never make good pets. They often carry diseases you can contract. A license from the state Department of Natural Resources is required to care for injured animals or birds. Wildlife rehabilitators are trained and licensed to care for injured or truly orphaned wildlife.  It is illegal to have a wild bird, mammal or reptile as a pet unless you have a state license to do so.
