Ecological factors determine tree-planting success along an urban greenway
Supporting Urban Biodiversity Along the High Line Canal
Metro DNA is proudly supporting six demonstration projects in the metro Denver region that exemplify cohesion of our Regional Equity and Conservation Assessments and support productive alliances for people and nature. As a recipient of one of our 2024 demonstration project grants, the Eco Factors Tree Success project, led by Denver Botanic Gardens in partnership with the High Line Canal Conservancy, is focused on enhancing the health and sustainability of the tree canopy along the High Line Canal. This 71-mile-long ecological corridor is essential for supporting urban biodiversity, but its trees face significant challenges from aging, drought, and reduced water flow in a semi-arid climate.
Optimizing Tree Health Through Research
The project investigates how various environmental factors—such as soil moisture, light availability, and topography—affect the survival and growth of both native riparian and non-native xeric trees. By focusing on the critical first three years post-planting, the project aims to identify the key drivers of tree health to optimize planting success. This research is crucial for urban municipalities that invest in tree planting and maintenance, providing evidence-based recommendations for species selection and management strategies in the face of climate change.
Resilient Tree Canopy for Urban Communities
The Eco Factors Tree Success project will directly benefit the 350,000 residents who live within one mile of the Canal by ensuring a healthy, resilient future tree canopy. The data collected will guide land managers in selecting trees that can thrive in challenging urban conditions, for example in under-resourced neighborhoods where heat island effects are more severe. In addition to its ecological focus, the project engages communities through partnerships with educational institutions and local organizations. By connecting diverse audiences to the importance of urban forestry, the project fosters environmental stewardship and inclusivity, furthering Metro DNA’s mission to promote equitable access to nature.
