Four teenaged girls recently assisted the Detroit Zoological Society (DZS) with our amphibian conservation efforts by pairing up with staff members to build mudpuppy shelters at the Detroit Zoo’s Ford Education Center. These young ladies were from Oakland County’s Children’s Village, a residential treatment and detention center for youth. The DZS began a partnership with Children’s Village in 2009 to instill respect and reverence for wildlife and wild places within the hearts of these teenagers. The program expanded in 2016 to offer off-site community service opportunities for the residents.
Mudpuppy shelters are an important piece of our ongoing conservation work as we monitor the population of these aquatic amphibians on the shorelines of the Detroit River and the inland lakes of Belle Isle. Mudpuppies are indicators of water quality; they cannot survive in polluted or contaminated water, so their presence is a sign of a healthy aquatic ecosystem.
DZS amphibian staff provided the specifications for the height, width and depth of these cement structures, as well as the materials to make them. The young ladies worked in pairs with DZS staff members, donning thick gloves and using wire cutters to trim heavy-duty wire mesh, before folding and binding it to form the bottom of the shelter. They then layered the cement over the wire mesh and built it into a solid, smooth floor and walls. Separate pieces of wire mesh were then cut to size and layered with the cement mixture to create roofs for the shelter.
Once the weather warms up, the shelters will be placed in the water around Belle Isle in hopes that mudpuppies will find them a desirable place to lay their eggs. They tend to lay their eggs under rocks in their natural habitat, which makes it difficult for researchers to locate the eggs without potentially disturbing them by having to move rocks. With the easy-to-remove roof on these homemade shelters, mudpuppies could lay their eggs inside and DZS staff would be able to lift the top and easily check on the eggs without disturbing them.
The young ladies who helped build the shelters will join us down on Belle Isle in the coming weeks to place them in the water. They will have the opportunity to work alongside DZS amphibian and education staff to record weather, water quality and shelter placement as well as check on previously placed shelters.
These teens are facing many challenges in their lives and working alongside scientists in the field offers them the chance to explore careers they may not have otherwise known about or considered. It is an opportunity for them to try a new experience, build skills and understanding, and give back to the community through conservation.
