Climate change is affecting the trees in metro Detroit.

The Eastern U.S. experienced an oppressive heat wave recently. There were also a handful of severe thunderstorms that inevitably brought down branches, limbs, or even whole trees across the region. 

In Detroit, fewer than 60% of households have air conditioning, according to American Forests. That makes shade a vital source of relief from the heat.

So how is Detroit’s tree canopy doing in the face of climate change? And if you want to plant your own tree, what species will be resilient for decades to come? To find out, Metro producer David Leins spoke with Lawrence Law, urban forester and partnership coordinator for the Michigan Department of Natural Resources.

Heat is now the leading cause of weather-related deaths in the U.S. — with 12,000 lives claimed annually — and this number is expected to increase significantly by the turn of the century.

In large cities, temperatures in the summer can reach even higher than normal due to the “urban heat island” effect. 

New data compiled by the nonprofit American Forests and the UCLA Luskin Center for Innovation identifies areas in cities across the United States that lack enough protection from the sun.  These areas are known as “shade deserts.” 

The new shade map covers more than 100 of the country’s biggest urban areas, including Detroit.

One effective way to stay cooler is by increasing shade, especially through planting trees, which can reduce the effects of high temps significantly. But according to American Forests a lack of shade in Detroit — especially at bus stops and along roadways — is harming thousands. 

Less than 60% of households in Detroit have air conditioning, said Chris David, vice president of GIS & Data Science at American Forests. Additionally, he says those using public and alternative transit are even more at risk of heat-related illness and death. 

“I think there’s about 5,000 bus stops in Detroit,” David said. “About 90% of those 5,000 bus stops have poor shade.” 

He says bus shelters provide “very little” sun protection, with only about 5% of bus stops in the city covered.  

“That means we estimated about 85,000 daily transit riders in Detroit….they’re left exposed to the sun when they’re waiting for the bus… and that can have dire effects,” David said.

David says Detroit will benefit from a strategic plan to increase the tree canopy, with groups like the Greening of Detroit working toward that goal in partnership with city government.
