Example 1: Water Extraction ProjectExample 1: Water Extraction Project

Management QuestionsManagement Questions • How will increased water extraction impact phreatophytes?

• Can phreatophytic communities act as indicators of impacted groundwater systems?

Pilot ProjectPilot Project• Identify locations of phreatophytic communities and correlate with

aquifer flow system conditions. • Identify areas at risk from increased water withdrawals.

18

Water Extraction ProjectWater Extraction Project

Pilot Project TasksPilot Project Tasks1. Map phreatophytic land cover by categorizing evapotranspiration as a

function of critical characteristics: Geomorphology, vegetation species composition, elevation, hydrology

2. Map groundwater change over time

3. Evaluate change over time to phreatophytic land cover

Applicability to Management QuestionsApplicability to Management Questions• Provides assessment of status and trends of groundwater

• Establishes dataset of phreatophyte coverage across Great Basin

• Identifies environmental areas of concern or sensitivity

• Addresses utility of phreatophytes as indicators of impacts to groundwater system

• Develop tools that help to predict and manage for the effects of groundwater extraction across the Great Basin

Example 2: Fire and Invasive SpeciesExample 2: Fire and Invasive Species

Management QuestionsManagement Questions

• How should managers prioritize efforts to manage fire cycles with the goal of retaining and restoring desired plant communities?

Pilot ProjectPilot Project• Use spatial patterns of fire and landscape characteristics to evaluate

how invasive plants have altered fire regimes

• Create models and a sampling design to monitor and assess changes in fire regimes and vegetation over time

21

Fire and Invasive SpeciesFire and Invasive SpeciesPilot Project TasksPilot Project Tasks

1. Create maps of fire distributions over time in the Great Basin

2. Evaluate hypotheses on how invasive plants have altered fire regimes and how these relationships may change in the future

3. Create models and a sampling design to monitor and assess changes in fire regimes and vegetation over time

Applicability to Management QuestionsApplicability to Management Questions

• Develop tools to monitor and predict fire regimes among major vegetation types

• Evaluates and predicts trends for altered fire regimes among major vegetation types

• Assesses vegetation types at risk to altered fire regimes due to invasive species, landscape characteristics, and climate change scenarios

• Prioritizes major vegetation types for suppression and mitigation actions designed to prevent the establishment of grass/fire cycles

• How are different land treatments influencing vegetation and wildlife habitats?

• How and where can land managers use land treatments to achieve multiple objectives, including maintaining and restoring wildlife habitat?

Pilot ProjectPilot Project

• Synthesis of monitoring efforts in the Great Basin

• Assess and predict effects of land treatments at various scales on wildlife habitat

• Initial focus on areas in Utah and the tri-states targeted for HLI funding

• Eventually expand to rest of Great Basin

24

Pilot Project TasksPilot Project Tasks1. Create relational database of treatment information (1950 to present)

Treatment description, monitoring information, spatial data, reference photos, etc.

2. Develop predictive models on effects of treatments on wildlife habitats

3. Evaluate which land treatments can be used to improve habitat connectivity and where they can be placed (in a landscape context)

Management ApplicationManagement Application• Establishes a common database and maps of land treatments

across Great Basin

• Provides predictive models that estimate effects of land treatments on wildlife habitats, particularly sage grouse and other high profile species

• Provides information on treatment effectiveness
