When our native flowering dogwood tree was laid waste by an imported fungus in the 1970’s, the east Asian kousa dogwood was widely planted as a disease-resistant replacement.  After 50 years, however, it has turned invasive.  Dr. Bethany Bradley of the University of Massachusetts Amherst explains that such a “lag period” is common among introduced plants and why this makes plant introduction a very risky gamble.

Policy makers have promoted tree planting as a way to sequester carbon and fight climate change, but grassland advocates say that native prairie is more effective in some circumstances and provides unique ecological benefits.  Dr. Jessica Gutknecht of the University of Minnesota examines the opportunities and limitations of this approach, and the potential impact of backyard prairies such as her own.

Gardening consumes an enormous amount of plastics, 1.66 billion pounds annually in the U.S. according to the most recent figures, most of it in the form of single-use, unrecyclable pots.  Ecological landscape designer Marie Chieppo has made it her mission to change this.  Learn about how her work is promoting recycling, changes in design to use less plastic, and a switch where possible to biodegradable and compostable substitutes.
