Addressing Climate Change by Creating a Greener Community

As you walk through The Detroit Zoo, you may notice a lot of trees (follow along on our Trek). Trees are essential to the health of people, animals and the planet, which is why we are committed to taking steps to reduce our carbon footprint by adding even more to our lush grounds.

The Detroit Zoological Society (DZS) pledged to add a total of 2,000 trees by the end of 2022 to our campuses and in Metro Detroit communities. The average tree absorbs 48 pounds of carbon dioxide (CO2) and 1,673 gallons of storm water every year. Adding 2,000 trees (to the 7,000 trees currently growing at the Detroit Zoo), will make a big difference for nearby communities by helping to improve air and water quality. We have partnered with ReLeaf Michigan to help us organize group planting projects across Metro Detroit. 

In 2021, the DZS planted 641, and we have full confidence in our ability to plant our total goal by the end of this year. Most recently, Oakland County planted five trees donated by the DZS in celebration of Earth Day 2022.

We are well on our way to achieving our goal of making the world a greener place through sustainable practices such as tree planting.

In addition to other environmental benefits, trees and other vegetation reduce heat island effect (urbanized areas experiencing higher than average temperatures) by providing shade. According to the EPA, shaded surfaces may be 20–45°F cooler than the peak temperatures of unshaded materials. The benefits from trees don’t stop there – they also provide shelter and food for birds, insects, and other critters such as squirrels. These animals then disperse the trees’ seeds, allowing new saplings to grow. 

We are meticulously selecting a variety of species of trees to add biodiversity to our campus, as well as focusing on native species, browsable trees (clippings that make great snacks for the animals who live at Detroit Zoo), habitat value (for example, birds are attracted to oak trees), and resistance to climate change.

Our tree planting initiative is only one of the steps we are taking to create greener future. The DZS has developed a unique, green roadmap called the Greenprint. This evolving plan guides our operations and is the plan by which we refine and improve our facilities and daily practices, develop new policies and programs and improve green literacy and action in our community.
