Zion National Park is known world-wide for its amazing scenery. An integral part of that scenic experience is the vegetation found throughout the landscape. Zion has made an effort to blend into that landscape, both by using stone and other natural building materials and by designing with native plants.
The Zion Canyon Visitor Center, Emergency Operations Center, and Lodge landscapes were all designed using native plants, blending both the natural and cultural resources of the park. Native plants are the most environmentally-friendly way to landscape. They conserve resources, expand habitats, minimize pollution, prevent noxious weeds from establishing, maintain biodiversity, and are inherently beautiful. They are, by definition, the most sustainable option because their unique adaptations allow them to thrive naturally, without human interaction.

Although some irrigation is necessary in the park's most visited areas, Zion is constantly exploring the most efficient irrigation methods. Currently, many of the landscapes are watered with filtered river water to cut down on treated water use. Point-source irrigation (drip emitters, bubblers, drip line, and root zone systems) and proper scheduling help minimize loss from evaporation.
