Impacts of umbrella species management on non-target species

Restoration of anthropogenically altered habitats has often focused on management for umbrella species—vulnerable species whose conservation is thought to benefit co-occurring species. Woody plant encroachment is a form of habitat alteration occurring in grasslands and shrublands around the globe, driven by anthropogenic shifts in disturbance regimes. One pervasive threat to historically widespread sagebrush communities is conifer expansion, which outcompetes sagebrush and can negatively affect sagebrush-obligate animal species. Degradation and loss of sagebrush plant communities in western North America have been associated with drastic declines in wildlife populations. The imperiled Greater Sage-Grouse is assumed to be an umbrella species for the sagebrush community, so habitat restoration, including removal of encroaching conifers, is commonly targeted toward sage-grouse. How this conservation action affects the demography of species other than age grouse is largely unknown. We quant..., Density
To understand how treatment impacted breeding pair density, we used spot-mapping to create territory maps in each year of the study (Chalfoun & Martin, 2007; Ralph et al., 1993). We surveyed all plots 3-5 times throughout the breeding season and mapped every bird seen and heard. The 50m grid of points was used to assist with the accurate identification of bird locations using a GPS unit and visual distance estimation. We paid attention to males that were counter-singing to determine territory boundaries. Using the spot-mapping observations and nest locations, we created a territory map for each species each year of the study. We assumed that every territory held a pair of birds and if a territory overlapped the plot boundary, then it was considered half of a territory. We used the final territory maps to estimate the number of pairs of each species on each plot and divided by plot area to calculate density.

This dataset consists of species abundances as collected by territory mapping surveys and nest data. Data used to calculate species density, number of offspring produced, and daily nest success between treatments are included.

## Description of the data and file structure

The data are set up in CSV format for easy import into R. All data analysis was conducted in R (version 4.3.0) and important packages included nlme and lme4 for modeling and ggplot for plotting.

Territory data includes the year, species (SPP, common names associated with four-letter codes can be found in Table 1), plot, treatment, number of territories in the plot, and plot area in hectares.

Nest data includes a row for each nest found and consists of the year, nest ID (NID), species (SPP, common names associated with four-letter codes can be found in Table 1), plot, tr...
