Tuzigoot National Monument preserves a 2- to 3-story pueblo ruin on the summit of a limestone and sandstone ridge just east of Clarkdale, Arizona, above the Verde River floodplain. The Verde River is the only Wild and Scenic River in Arizona. Diverse assemblages of vegetation, mammals, birds, amphibians, and reptiles offer amazing opportunities for scientific inquiry and interpreting the relationship between the long history of human habitation throughout the Verde Valley and the area’s environment.

Traditional NRCA Report: 2019

Montezuma Castle and Tuzigoot National Monuments are managed jointly. Their Natural Resource Condition Assessment was a collaborative effort between the park staff and other NPS partners. The NRCA for Montezuma Castle and Tuzigoot National Monuments was published in 2019 after analysis of resources with high ecological significance. Ten natural resources were evaluated in this assessment:

- Landscape dynamics

- Riparian vegetation

- Air quality

- Birds

- Hydrology

- Mammals

- Water quality

- Fish

- Upland vegetation and soils

The majority of resources were found to be in good condition or of moderate concern. Exceptions include fish due to the low diversity of species, which is considered to be of significant concern, and aspects of riparian vegetation due to the presence of invasive, non-native plants. The primary threats to resource conditions within the monuments and throughout the surrounding area include increasing temperatures, drier conditions due to reduced precipitation, changes in adjacent land use due to increasing developments, and increasing water use. Maintaining or improving the Monuments’ resource conditions in light of rapidly changing environmental conditions, such as invasive plants and animals, increasing temperatures, decreasing precipitation, and land use change is challenging. The Monuments’ proximity to the Coconino National Forest provides outstanding opportunities for developing partnerships to achieve shared conservation goals. With the number of landscape-scale changes that are occurring, landscape-scale coordination of resource protection is paramount to resource preservation.
