Nebraska Zoo Fights Invasive Species By Feeding Them to Their Animals

Nebraska Zoo Animals Play Key Role in Grassland Restoration by Consuming Invasive Plants

The collaboration between Omaha’s Henry Doorly Zoo and The Nature Conservancy has a significant impact on the conservation efforts in Iowa’s Folsom Point Preserve. The invasive trees and shrubs encroaching on the natural grasslands are being addressed through a unique approach involving the zoo’s animal residents. Giraffes, elephants, and various other animals at the Nebraska zoo are now incorporating invasive plant species into their diets as part of this mutually beneficial partnership.

The invasive tree and shrub takeover in TNC’s Folsom Point Preserve not only disrupts the natural grassland ecosystem but also has detrimental effects on the habitat and wildlife in the area. The encroachment causes depletion of groundwater, alteration of soil health, and competition with native prairie plants for essential resources. By utilising the clippings from the invasive plants at the preserve, the zoo is contributing to the preservation of the grasslands while providing supplemental food for their animals.

According to Graham McGaffin, TNC’s Iowa State Director, the collaborative effort between The Nature Conservancy and Omaha’s Henry Doorly Zoo signifies a turning point in their conservation initiatives. By repurposing the vegetation cleared from the preserve as animal feed, both organisations are minimising waste and promoting sustainability in their practices. The partnership showcases a creative solution to a pressing environmental challenge while fostering a stronger commitment to conservation efforts.

Dr. Cayla Iske, the director of nutrition at Omaha’s Henry Doorly Zoo, emphasises the significance of the collaboration with TNC in managing the encroaching trees and shrubs at Folsom Point Preserve. The processed plant materials, known as “browse,” not only serve as a vital dietary component for the zoo’s animals but also encourage natural behaviours such as foraging and tree-stripping. This innovative approach not only benefits the animals’ health and enrichment but also aligns with the zoo’s dedication to conservation initiatives.

The partnership between the zoo and TNC highlights the importance of sustainable practices in wildlife conservation. By introducing a variety of invasive tree species such as dogwood, sumac, elm, mulberry, and boxelder into the animals’ diets, the zoo is promoting a holistic approach to environmental protection. Through careful consideration of each animal’s dietary preferences, the zoo ensures that the animals receive fresh, natural foods that support their well-being and encourage natural behaviours.

While the initiative at Folsom Point Preserve is a significant step towards addressing invasive plant species, TNC acknowledges that more efforts are needed to combat this environmental issue. In addition to the partnership with the zoo, TNC is collaborating with ranchers and the community to implement strategies such as prescribed burns and cutting days to manage the invasive plants effectively. By promoting the cultivation of native species in yards and gardens, individuals can also contribute to the preservation of local wildlife and habitats.

Overall, the collaborative efforts between Omaha’s Henry Doorly Zoo and The Nature Conservancy exemplify a proactive approach to wildlife conservation and environmental stewardship. By transforming a conservation challenge into a mutually beneficial solution, the organisations are not only safeguarding the grasslands and wildlife at Folsom Point Preserve but also setting a precedent for sustainable conservation practices. This innovative partnership serves as a model for wildlife institutions and conservation organisations worldwide seeking to address ecological challenges while promoting animal welfare and habitat preservation.
