LMLandscape Monitoring Framework (LMF)
• Low-intensity terrestrial monitoring network on BLM lands to satisfy national reporting requirements
• AIM Terrestrial Core methods
• Extension of NRI onto BLM lands
• Collected by NRCS crews
• Data available for use by local offices.
• ~9,000 points as of 2017

National-level sample points can be used for local applications – free to states, districts, or field offices
• Use of data to supplement local efforts
• Setting benchmarks or potential natural conditons

• Establish quantitative, baseline conditions
• Assess Land Health Standard attainment
• Identify priority stressors by region
• Inform more intensive, local monitoring and management actions

• Maintain sage-grouse habitat"% of seasonal habitat within 4.0 miles of leks meeting a majority of the desired conditions: Arid = 70 (55-85), mesic = 75 (60-90)". (Oregon Greater Sage-Grouse Approved RMP-A)
• Assess sage-grouse habitat suitability at multiple scales– Land Use Plan– Seasonal Habitat– Land Health Evaluations
(allotment)– Cross-scale interactions

Example Indicators:• Fine Sediment, Overhead cover, Bank Overhead cover,
Bank Stability, Bank Cover• Other lines of evidence: PFC assessments and site revisits
+ photos comparison

LMTreatment Effectiveness -- ES&R
Monitoring Goals and Applications
● Eagle Lake Field Office● Rush Fire: 315,578 acres
burned in CA and NV in 2012● Treatment Objectives:
establish native plants, establish ecological processes (hold soil), restore sage grouse habitat, prevent invasion
● Treatments: Drill Seeding and Aerial Seeding

LMES&R Treatment Objectives
● Total canopy cover is sufficient to provide for soil stabilization and site functionality. Greater than 70% canopy cover is present for the rangeland ecological site when compared to a control area that is in a similar unburned ecological condition.
● At the end of the second and third growing seasons the measure of success will be the presence of 3 seeded perennial grass plants per M² and 0.5 sagebrush plants per M².

LMES&R Design
In addition to LUP design, two intensifications for ES&R: ● Grazing allotments
impacted by the fire (burned/untreated + unburned)
● Treatment intensification (Drill seeding sites, aerial broadcast seeding sites; min 3 per seed mix)

LMES&R Results
Seeding treatments did not achieve objectives Timing, drought, and seed source likely contributed -- consider whether treatments are worthwhile given constraints

• Consistent data collected using consistent methods can be used for many different purposes (as seen in examples)
Conclusion:
• Application of AIM principles is flexible and driven by management and monitoring objectives
○ High flexibility: survey design, supplemental indicators
○ Low flexibility: changing of core methods, electronic data collection and mgmt.
