Abstract
The interface between natural and urban landscapes offers opportunities to promote sustainable landscape practices and strengthen human connections with nature.
Over the past 25 years, the restoration of the 26-ha viewshed at the mouth of Rock Canyon (Provo, Utah, USA) has demonstrated the limitations of relying solely on ecological science to guide restoration efforts.
Although empirical studies show that high-diversity native plantings can suppress weed reinvasion, site heterogeneity, and annual climate variability affect where and when native species will survive.
Horticulture and ecology, landscape architecture, stakeholder coordination, and public engagement are also essential for success.
During the past decade, major accomplishments included private land acquisition, establishment of a conservation easement, significant fundraising, and development of a collaborative framework among the United States Forest Service, Provo City, and environmental groups.
These efforts culminated in the Rock Canyon Master Plan, which was implemented from 2023 to 2024. Political support was secured by emphasizing wildfire risk reduction, pollinator habitat creation, cost-effectiveness, and public education.
This long-term project illustrates several key lessons: 1) science is not enough; 2) stakeholder engagement is key; 3) remove the weeds before planting the seeds; 4) volunteer training is critical; and 5) diverse habitats have diverse needs.
This case study demonstrates that ecological restoration at the wildland-urban interface is inherently multidisciplinary.
The integration of ecological science, landscape architecture, and civic engagement is essential for achieving resilient and aesthetically pleasing landscapes.
The Rock Canyon project provides a replicable framework for long-term success.
