More: Conservation Ambassador Tilia is the first on-staff conservation dog in the state of Wisconsin! She also serves as a conservation ambassador and joins Mequon Nature Preserve staff on field trips --teaching over 10,000 students a year. Her main role involves her powerful nose! She works to sniff out both invasive plants and native animal species; making her a vital tool for the Mequon Nature Preserve restoration crew. Tilia enjoys naps, food (especially bananas), and lots of cuddles!
