Description

The greater sage-grouse, a candidate species for listing under the Endangered Species Act (ESA) of 1973 has experienced population declines across its range in the sagebrush steppe ecosystems of western North America. Sage-grouse now occupy only 56% of their pre-settlement range, though they still occur in 11 western states and 2 Canadian provinces.

Abstract

In Canada, Greater Sage-Grouse (Centrocercus urophasianus) are considered an endangered species by the Committee On the Status of Endangered Wildlife In Canada (COSEWIC), due to declining population numbers and distribution. Encroachment of agriculture and subsequent destruction of suitable sagebrush (Artemisia spp.) habitat is thought to be responsible for historical population declines However, subtle changes in habitat quality may also result in reduced escape and nesting cover, which may lead to increased levels of predation. We examined the influence of vegetation cover and height on the fate of artificial Greater Sage-Grouse nests Because most natural sage-grouse nests are associated with sagebrush, we predicted that sagebrush height and cover would be crucial to the success of nests. Lateral cover is important in protecting nests from detection by predators, and thus we predicted that nests surrounded by shorter grass would suffer greater predation rates than nests with taller grass. To experimentally test this hypothesis, we trimmed grass surrounding some artificial nests Richardson's ground squirrels (Spermophilus richardsonii) were the primary predators of artificial nests, with some predation by corvids and badgers (Taxidea taxus). Successful nests tended to be surrounded by shorter sagebrush, taller grasses, and taller, denser forbs than predated nests. Trimming grass around nests did not affect nest fate However, ground squirrels typically attacked nests with less forb cover and fewer sagebrush, and avian predators tended to destroy nests at inactive leks with greater lateral cover. Thus, lateral cover provided by forbs and sagebrush appeared to be important for protecting nests from mammalian predators. These results suggest implementing management strategies that improve sagebrush habitat by providing tall, dense forbs and sagebrush, which could increase Greater Sage-Grouse nest success and recruitment.

Abstract

The Alberta greater sage-grouse population has declined by 66-92% over the last thirty years. Previous research in Alberta suggested that the population has declined as a result of poor recruitment. Low levels of recruitment appear to be linked to poor chick survival as a result of limited mesic sites important for brood rearing habitat. Due to the inaccuracies of brood flushing counts, and the limits of technology to produce transmitters small enough for chicks, it has been difficult to accurately assess and understand chick survival. A population model developed from data gathered in 1998 and 1999 suggested that the population would decrease in 2000, resulting in a decrease in the number of males observed on leks from 140 to 132. I counted 140 males at leks in 2000, suggesting that the population remained relatively stable, at between 420 and 622 individuals. While sample sizes were small, measures of productivity in 2000 were quite low compared to previous years, suggesting a better understanding of the variability in the parameters in the model is needed. I also performed a 2-stage pilot experiment, focusing on attaching transmitters to sage-grouse chicks. I first practiced the technique by suturing transmitters to 10 chicken chicks, and then tested the technique on 4 sage-grouse chicks in the field. The transmitters did not appear to harm the chicks at all, and none of them showed signs of infection, bleeding, or scaring from the transmitter attachment. This technique appears to be a viable method for assessing chick survival.

Effects of predation and hunting on adult sage grouse Centrocercus urophasianus in Idaho

Keywords

Abstract

Although sage grouse Centrocercus urophasianus have declined throughout their range in North America, little is known about annual mortality patterns of this species. Thus, we summarize a long-term data set on timing and causes of mortality of sage grouse. Predation was the most common cause of death for radio-marked sage grouse. For adult males, 83% of deaths were attributed to predation and 15% to hunting. However, for adult females, 52% of deaths were caused by predation while 42% were attributed to hunting. We rejected the hypothesis that type of mortality (predation vs hunting) was independent of gender of sage grouse. For males, 70% of deaths occurred during spring and summer (March-August) and 28% occurred in September-October. For females, 52% of mortalities occurred during spring and summer and 46% occurred in September-October. We rejected the hypothesis that time of death is independent of the gender of sage grouse. In six of 15 years (40%), harvest rates for adult females may have exceeded 10% while this rate was only exceeded in two of 15 years (13%) for adult males.

Abstract

The sage grouse Centrocercus urophasianus population level on the Upper Snake River Plain of Idaho has declined significantly over the past 40 years. We investigated migration patterns and seasonal ranges of these birds to compare to patterns from the 1950s and 1960s. Furthermore, we examined landscape changes that occurred between 1975 and 1992. Migration patterns have not changed since the 1950s. The grouse currently migrate up to 125 km and use an annual population range of at least 2,764 km(2). The major landscape change since 1975 that occurred in sage grouse habitat was a decline in the total amount of winter range. Between 1975 and 1992, 29,762 ha of sagebrush Artemisia spp. rangeland were converted to cropland, a 74% increase in cropland. Regression analysis suggested a relationship between sagebrush habitat loss and grouse population decline (R-2 = 0.59, P = 0.002). Approximately 1,244 km(2) of privately-owned sagebrush on the study area could potentially be converted to cropland, which we predict would have serious negative implications for the sage grouse population.

Abstract

Prescribed burning is a common method to eliminate sagebrush (Artemisia spp.) and has been suggested as a tool to enhance the habitat of sage grouse (Centrocercus urophasianus). Effects of this practice on sage grouse have not been evaluated rigorously. We studied effects of prescribed fire on lek (traditional breeding display areas) attendance by male sage grouse occupying low-precipitation ( P > 0.10). During the postburn period (1990-94), male attendance at treatment leks declined 90% and control leks declined 63%. Although declines were similar between treatment and control leks during the preburn period, postburn declines were greater for treatment than control leks (0.05 < P < 0.10). We rejected the null hypothesis that for the 2 largest leks in both the treatment and control areas, counts were independent of years for preburn (0.05 < P < 0.70) and postburn (P less than or similar to 0.05) periods and concluded that breeding population declines became more severe in years following fire. Prescribed burning negatively affected sage grouse in southeastern Idaho and should not be used in low-precipitation sagebrush habitats occupied by breeding sage grouse.

Suitability of shrub establishment on Wyoming mined lands reclaimed for wildlife habitat

Abstract

Restoring coal mined land to pie-mining shrub cover, density height, community composition, and diversity to renew wildlife habitat quality is a priority for reclamation specialists. Long-term shrub reestablishment success on reclaimed mined land in Wyoming and suitability of these lands for wildlife habitat are unknown. Fourteen reclaimed study sites, 10 yr old or older, were selected on 8 mines in Wyoming to evaluate shrub reestablishment and wildlife habitat value for antelope (Antilocapra americana) and sage grouse (Centrocercus urophasianus). Five sites were categorized as fourwing saltbush (Airplex canescens) sites and 9 as fourwing saltbush/big sagebrush (A. canescens/Artemisia tridentata spp. wyomingensis) sites. Published data describing antelope and sage grouse-preferred habitat requirements in sage-brush-grassland ecosystems were used to evaluate shrub community value of sampled sites for wildlife habitat. Mean shrub canopy cover, density, and. height for fourwing saltbush sites were 5.8%, 0.23 m(-2), and 41.6 cm, respectively compared to 5.6%. 0.61 m(-2), and 31.1 cm for fourwing saltbush/big sagebrush sites. Two fourwing saltbush and 4 fourwing saltbush/big sagebrush sites provided sufficient cover for antelope, while 2 fourwing saltbush and a fourwing saltbush/big sagebrush sites were adequate for sage grouse. Only 1 fourwing saltbush/big sagebrush site provided high enough shrub densities for sage grouse. One fourwing saltbush and 7 fourwing saltbush/big sagebrush sites provided ample shrub heights For antelope, while 1 fourwing saltbush and 8 fourwing saltbush/big sagebrush sites were sufficient for sage grouse, One fourwing saltbush and 1 fourwing saltbush/big sagebrush site provided enough grass, forb,, and shrub composition for antelope, while no site in either reclamation type was satisfactory for sage grouse. Shrub diversity was 3 times higher for fourwing saltbush/big sagebrush sites (0.984) than for fourwing saltbush sites (0.328). Individually, sites seeded with multiple shrub species had higher canopy cover, density, and diversity compared with single-species shrub seedings. Achieving pre mining shrub cover, density, height, community composition, and diversity within existing bond-release time frames is unrealistic, considering that some native shrublands require 30-60 yr to reach maturity.

Directional acoustic radiation in the strut display of male sage grouse Centrocercus urophasianus

Keywords

Abstract

We present evidence that the acoustic component of the strut display of male sage grouse Centrocercus urophasianus is highly directional and that the nature of this directionality is unique among measured vertebrates. Where vertebrate acoustic signals have been found to be directional, they rare most intense anteriorly and are bilaterally symmetrical. Our results show that sage grouse acoustic radiation (beam) patterns are often asymmetric about the birds' anterior-posterior axis. The beam pattern of the 'whistle' note is actually strikingly bilobate with a deep null directly in front of the displaying bird. While the sage grouse display serves to attract potential mates, male sage grouse rarely face females head on when they call. The results of this study suggest that males may reach females with a high-intensity signal despite their preference for an oblique display posture relative to those females. We characterized these patterns using a novel technique that allowed us to map acoustic radiation patterns of unrestrained animals calling in the wild. Using an eight-microphone array, our technique integrates acoustic localization with synchronous pressure-field measurements while controlling for small-scale environmental variation in sound propagation.
