Water creates distinct communities inside otherwise dry landscapes.
Water creates distinct communities inside otherwise dry landscapes. Zion's plant overview separates riverbank vegetation, saturated wetlands and hanging gardens fed by sandstone seeps. Cottonwoods belong to the river story; ferns, mosses and wildflowers can occupy shaded seep habitats. These are related through water, but they are not interchangeable environments.
The profiles here connect through the processes they describe. Fremont cottonwood and alcove columbine show two different kinds of water-dependent plant life, while beaver and native cutthroat trout show how animals shape and use a stream. Beaver activity, stream restoration and fish recovery all depend on the particular water, so one dam does not help every fish and one treatment does not suit every stream. The western toad and northern leopard frog add another reason to be careful in wet places: stay on established routes and leave plants, eggs and animals where they are.
A broad-crowned river tree whose new generations depend on the right combination of flowing water, exposed sediment, and moisture.
A small-flowered columbine of seeps and hanging gardens, where groundwater creates a cool refuge within the desert.
A paddle-tailed rodent whose feeding and construction can transform a stream into a complex wetland.
Utah's native trout, with distinct drainage histories and restoration needs that a familiar throat mark cannot tell on its own.
A warty mountain amphibian whose breeding waters and disease risks require a light touch from visitors.
A spotted frog that needs a connected mix of breeding water, moist feeding ground and overwintering habitat.
