Boosted by a major planting in 2015, the collection now includes almost 50 trees. This tree walk identifi es trees planted as part of the Learning Landscape as well as other interesting specimens at the school. What is a Learning Landscape? A Learning Landscape is a collection of trees planted and cared for at a school by students, volunteers, and Portland Parks & Recreation (PP&R) Urban Forestry staff. Learning Landscapes offer an outdoor educational experience for students, as well as environmental and aesthetic benefi ts to the school and surrounding neighborhood. Learning Landscapes contain diverse tree species. They are designed to teach students about biology and urban forestry issues, but can also be used to teach geography, writing, history and math, and to develop leadership skills. Community Involvement Community-building is crucial to the success of Learning Landscapes. PP&R works with Urban Forestry Neighborhood Tree Stewards, teachers, By involving students and neighbors in parents, students, and community members to design, the tree planting, the community has plant, establish and maintain these school arboreta. ownership of the trees and a tangible PP&R facilitates this collaboration by working with the school district, neighborhood, students and connection to their school. teachers to create landscapes that meet the need of the individual school community. Tree Planting Experience Learning Landscapes are planted by the school's students under the mentorship of middle or high school students and volunteers. On planting day, tree planting leaders teach students the benefi ts of urban trees, the form and function of trees, and tree planting techniques. This leadership aspect of Learning Landscapes gives older students and volunteers the opportunity to connect with their peers, build confi dence, and develop public speaking skills. Involving students and neighbors in the tree planting fosters community ownership of the trees and builds a tangible connection between school and neighborhood. This helps ensure a high tree survival rate by reducing vandalism and encouraging ongoing stewardship of the school's trees. Continued Hands-on Learning Opportunities Once planted, Learning Landscapes are used by teachers and parents for service and leadership projects. Students and teachers continue to build projects around the trees with opportunities to study and provide ongoing care, such as structural pruning. These dynamic landscapes change year after year, depending on student and teacher interests, as new trees are planted and added to the collection. How can I get involved?
