In an ever developing world, highways present a potential refuge of available space on which to plant trees to help mitigate the effects of climate change. However, this environment remains largely understudied and is often associated with high mortality. We are testing 4 different planting methods in highway interchanges and monitoring their effects on moderating temperature and runoff, limiting snow accumulation as well as testing differences in light and carbon stocking. Mortality rates and growth will also be monitored in each planting method. The aim is to identify a method which provides the most services, has the best survival and growth, but can also be achieved with the most reasonable budget; therefore, having the highest return on investment.
