Southeast wall of Arroyo del Cobre. Minas de Pedro copper mines are near the top of the picture in the ledge of light-colored sandstone which is about 400 feet above the floor of the canyon. Numberous fossilized leaves occur in the roof-shales of these mines, and John S. Newberry probably collected fossils from them in 1859. New Mexico. Published in U.S. Geological Survey. Professional paper 613-D, Figure 5, p.D-7. 1969.

The influence of landscape spatial structure on ecological processes has recently received much attention. Comparisons are made here between the spatial structure of grasslands, and active and extirpated Gunnison's prairie dog (Cynomys gunnisoni Hollister) towns at the Petrified Forest National Park, Arizona, U.S.A. The spatial structure of bare ground was quatified using a box-counting technique to extract landscape fractal dimensions, D, and bare-ground patch size. These landscapes are fractal, and active prairie dog towns had higher fractal dimensions, i.e. a more homogeneous spatial structure as D approaches 2, than inactive towns, which had higher fractal dimensions than unmodified grasslands. Morisita's index...

Previous studies have shown that landscape structure influences animal movement and population structure. In this study, we show an indirect interaction between beetles and prairie dogs due to prairie dog ecosystem engineering. Gunnison's prairie dog (Cynomys gunnisoni Hollister) towns have more bare ground and are structurally less complex than adjacent unmodified grasslands. This results in bare ground facilitating beetle movement. Differences in landscape structure between prairie dog towns and unmodified grasslands had a significant effect on the movement of the darkling beetle, Eleodes hispilabris Say. Beetle movement tended to be more linear (pathway fractal dimension approached 1) on prairie dog habitats...

Small pueblo made of sections of petrified logs in Petrified Forest National Park. The pueblo, now called "Agate House", was built and occupied by American Indians about 600 years ao. Recently, it was partially restored. Apache County, Arizona. Published in U.S. Geological Survey. Professional paper 613-D, Figure 3, p.D-4. 1969.

Ecosystem engineering by animals can create new habitats and increase the heterogeneity of the habitat mosaic that in turn can increase plant and animal diversity. Prairie dogs in North America alter both the above- and below-ground structure of the landscape and create novel habitats in grassland ecosystems. The ground-dwelling arthropod community associated with Gunnison's prairie dog modified habitats is compositionally different from that found in the surrounding grassland. Individual arthropod families and species have different distributions in both active prairie dog towns and inactive towns, compared to unmodified grasslands. These different responses to ecosystem engineering increase beta (between-habitat)...

These data are daily climate, water balance, and soil moisture data for 300 plots in the National Park Service (NPS) Southern Colorado Plateau Network (SCPN) Inventory & Monitoring (I&M) network. Climate data was collected from a gridded, daily climate dataset, Daymet (https://daymet.ornl.gov/). Climate, alongside field-collected soils (SoilDepthsByPlot.csv) and vegetation information, were then used to drive a point based, daily, multi soil-layer, ecosystem water-balance model, SOILWAT2 (https://github.com/DrylandEcology/SOILWAT2). SCPN plots were established to capture the range of ecosystem conditions present in this network. Plant communities of the SCPN are a vital sign for this region, enhancing habitat, stabilizing...

These data were simulated using the SOILWAT model and were intended to characterize soil-water conditions at different ecological sites on the Southern Colorado Plateau. SOILWAT is a daily, site-specific, multi soil-layer, ecosystem water-balance model, driven by daily meteorology, as well as site soil texture and vegetation. The sites simulated correspond with Inventory and Monitoring (I&M) plots established by the National Park Service’s (NPS) Southern Colorado Plateau Network (SCPN), which were established to capture the range of ecosystem conditions present in this network. Plant communities of the Southern Colorado Plateau Network (SCPN) are a vital sign for this region, enhancing habitat, stabilizing soils,...

The Petrified Forest National Park Vegetation Map Database was developed as a primary product in the Petrified Forest National Park Vegetation Classification, Distribution, and Mapping project. The map database maps vegetation at four levels of thematic organization at the park: the base, group, macro-group, and management map classes. Most of the base map classes represent plant communities identified to National Vegetation Classification associations. The associated report, Vegetation Classification and Distribution Mapping Report: Petrified Forest National Park, describes in detail the methods used to develop the map database and map classes. The project was sponsored by the USA-National Vegetation Mapping Program...
