SAGE-GROUSE TERRESTRIAL

HABITAT REQUIREMENTS

Nesting Requirements >20% Sagebrush Canopy Cover (Kolana et al. 2009)

>10% residual and live perennial grass cover if shrub cover is <25%(Coates et al. 2011; Kolada et al. 2009)

<5% Annual grass cover (Blomberg et al. 2012)

>30% total shrub cover (Coates and Delehanty 2010; Kolada et al. 2009 Lockyer et al. review)

Brood-Rearing/Summer >10% sagebrush canopy cover (Connelly et al. 2000)

>5% perennial forb canopy cover (Casazza et al. 2011 Lockyer et al. review)

SAGE-GROUSE TERRESTRIAL

HABITAT REQUIREMENTS

Project Design • Multi-resource monitoring

effort.

– Standards for rangeland health

– Grazing permit renewals

– Wild Horse & Burro management

– Sage-Grouse Habitat Management

– Aquatic Resources

– ES&R Actions

Analysis

• 297 AIM plots – Spatially balanced

– 2013, 2014 sample years

• Mean and standard error estimates calculated based on the weighted contribution of each point within sage grouse priority habitats

Management Actions

• Fire protection priorities and fuel breaks

• Emergency Stabilization and Rehab activities

• Invasive annual grass control

• Restoration activities (sage-brush, shrubs, forbs, invasive annual grasses)

• Grazing management

• Wild horse and burro management

Next Steps

• Continue collecting aquatic and terrestrial core indicators for the 2015 field season

• Include collection of supplemental indicators for riparian vegetation in 2015

• Utilize remote sensing and aquatic core indicators to answer management questions
