About this Page

The EcoChart is a pie chart showing the relative likelihood of observing particular other species commonly observed near Centrocercus urophasianus. Likelhood considers both the frequency with which Centrocercus urophasianus is observed at all locations where it has been reported, and the number of observations of all other species at each of those locations. A species that is common where Centrocercus urophasianus is common will have a higher score than if only one of these species is common at that location.
The Top Species lists enumerate those species most commonly observed near Centrocercus urophasianus.
While the chart, lists, and wheel are empirically based on observations, observations favor some phyla over others. Typically Bacteria, Fungi, Protozoa, and Arthropods are more common in the field than in our records.
In the section Characteristics of Habitat, we make some habitat inferences based on the known habitat preferences of those species most commonly associated with Centrocercus urophasianus.

Characteristics of Habitat

Range and Population:

Centrocercus urophasianus inhabits the shrubland ecosystems of south-eastern Canada (Alberta and Saskatchewan) and western USA (Washington, Montana, North Dakota, South Dakota, Wyoming, Idaho, Oregon, California, Nevada, Utah and Colorado)^2,3. It is closely associated with sagebrush Artemesia habitats during the breeding and non-breeding seasons, although some populations do undergo seasonal movements^2,3. Immense areas of its habitat have been cleared or degraded due to cultivation (for wheat, potatoes and other crops), burning and overgrazing, and the species has been extirpated from various parts of its former range (British Columbia, Nebraska, Kansas, Oklahoma, New Mexico and Arizona)³. Although the accurate estimation of trends is difficult, the rangewide breeding population was estimated as 142,000 individuals in 1998, clearly lower than historic levels¹, and decline rates have been estimated at 50% or higher since 1966⁴.[1]
