2 Management Objectives LUP GRSG Permit Renewal ES&R Baseline Climate change

3 Monitoring Objective Examples LUP Aquatic biological condition, as indicated by BMI, rated as minimal or moderate departure from reference for 80% of stream km with 90% confidence GRSG Sagebrush cover between 25% and 65% on 70% of area with 80% confidence. Permit Renewal Water quality meets state standards (e.g., EC < 700 µs/cm) on 80% of stream km with 90% confidence ES&R 70 % perennial plant cover of an unburned, similar ecological site, on 80% of the treatments.

4 Study Area Four level III ecoregions Precip: mm Elevation: 1,400 2,400 m > 10,000 km 2 & 450+ stream km Management drivers Grazing (including WH&B) Greater sage-grouse + other SOCs Fire, roads, archeology

5 Survey design - Terrestrial Target populations BLM rangelands within o Field offices in NorCal o Rush fire and surrounding allotments o ES&R Treatments within the fire Reporting units o All three FOs o Individual FOs o Allotments (especially Rush Fire) Strata o Remote-sensing-derived strata to help ensure distribution of locations (in absence of ecological sites)

6 Survey Design - Terrestrial Sample Design o Annual intensifications in allotments for grazing permit renewals o Intensification in Rush Fire area o ESR Treatment areas

7 Target population: perennial streams and rivers on BLM lands: > 550 km Reporting units: o All three FOs o Individual FO o Two grazing allotments Home Camp Twin Peaks Survey design - Aquatic Strata: none besides reporting strata

8 Survey design - Aquatic Target population: perennial streams and rivers on BLM lands (> 550 km defined by NHD) Reporting units & sample sizes: o All three FOs: 75 o Individual FO: 25 o Two grazing allotments Home Camp: 15 Twin Peaks: 15 Strata: none besides reporting units Site selection weighted by stream order

9 Indicators Aquatic Core Contingent TN & TP Instream habitat complexity Bank angle Longitudinal profile Terrestrial Core Plant density (ES&R only) IIRH

10 Condition Thresholds - Aquatic Chemical, physical and biological condition classes based on: Least disturbed conditions or best available conditions o Source: EPA, USGS & CA, NV & OR regulatory agencies

11 Condition Thresholds - Aquatic Used Least disturbed conditions to establish condition classes (e.g., good ; Poor ): Option 1: Range of reference conditions by ecoregion Range of REFERENCE fine sediment values among ecoregions % fine sediment > 95 th Unsuitable < 95 th & > 75 th Marginal < 75 th Suitable Sierra Nevada C. Basin and Range

12 Condition Thresholds - Aquatic Option 2: Predicted natural condition

13 Condition Thresholds - Terrestrial GRSG-Peer reviewed literature 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 Lockyer et al. review) Brood-Rearing/Summer >10% sagebrush canopy cover (Connelly et al. 2000) >5% perennial forb canopy cover (Casazza et al Lockyer et al. review) Winter >10% sagebrush canopy cover (Connelly et al. 2000) >9.8 inches (25 cm) sagebrush height (Connelly et al. 2000)

14 Condition Thresholds - Terrestrial Sandy Ecological Sites Bare Ground Canopy Gaps > 2m Total Foliar Cover Reference ranges from draft ESDs (all ecological sites within groups) 10 th & 90 th Percentile from field data 25 th & 75 th Percentile from field data 50 th Percentile from field data

15 Aquatic Results Sample frame versus sampled population All Field Offices Alturas Eagle Lake Surprise Twin Peaks Home Camp Light grey: Target sampled Black: Target not sampled Dark grey: Nontarget 0% 20% 40% 60% 80% 100% Percent of NHD stream kilometers 166 of the 445 stream km = non-perennial

16 LUP - Aquatic biological condition, as indicated by BMI, rated as Suitable or Marginal for 80% of stream km with 90% confidence Aquatic Results

17 Aquatic Results Permit renewal - Aquatic biological condition, as indicated by BMI, rated as Suitable or Marginal for 80% of stream km with 90% confidence Macroinvertebrate MMI scores

18 Aquatic Results Priority chemical, physical and biological indicators by FO

19 Aquatic Results Priority chemical, physical and biological indicators by allotment

20 Terrestrial Results LUP: Proportion of rangelands with >20% in large canopy gaps (>2m) Allotment Level Field Office Level

21 Terrestrial Results GRSG: Proportion of rangelands with sagebrush cover between 25% and 65% Allotment Level Field Office Level

22 Terrestrial Results ESR: greater than 70% perennial foliar cover is present when compared to a control area that is in a similar unburned ecological condition Perennial Plant Foliar Cover Year 1 Objective Achieved Objective Not Achieved
