The Treasure Valley (TV) of Idaho is an arid valley in the southwest portion of the state that contains the state’s largest city, Boise and surrounding metropolitan area. ​A regional Urban Tree Canopy (UTC) Assessment was performed for the TV in 2013. This assessment documented 10% UTC for the Treasure Valley (9 municipalities including: Boise, Caldwell, Eagle, Garden City, Kuna, Meridian, Middleton, Nampa, Star) and 16% UTC for the City of Boise. In Boise's 2015 Community Forestry Strategic Management Plan, stakeholders set a goal of maintaining the current level of tree canopy and increasing to the range of 16-25%. The eight other municipalities in the TV do not currently have a UTC goal. An interconnected Regional Trail Network (RTN) can be one way to attract fresh stakeholders and new areas of support to help energize the efforts to grow the Treasure Valley UTC. How can an interconnected Regional Trail Network (RTN) help to increase sustainability and growth of the Treasure Valley UTC? This study will analyze how a RTN can garner wide support for sustainability and increase of the UTC of a region by identifying opportunities for multi-use trail expansion. One trail being proposed is a 28 mile Rail with Trail connecting the cities of Nampa, Meridian and Boise, ID. Using this project as an example this study will examine how the cultural, economic and environmental factors of sustainable urban forestry can be leveraged to ensure equitable access and gain broad support of Urban Forest (UF) and RTN initiatives. By analyzing other cities where similar Regional Trail Networks have been successfully completed (Atlanta Beltline, Singapore) this study will describe UF benefits and discuss/predict future benefits that may be provided along with ways to gain new support for regional trails and the UF.
