MONITORING & EVALUATION

HEP/VEGETATION BASELINE TRANSECTS - 1992

CONDUCTED WILDLIFE SURVEYS

MONITORING & EVALUATION

Replicated HEP transects-2000

Established vegetation transects using M&E protocols

Monitored sharp-tailed grouse leks and neo-tropical birds etc.

Grassland fertilizer trials

M&E RESULTS – VOR M&E RESULTS – VOR

Null hypothesis (Ho): VOR measurements observed

in 1992 and 2000 are equal

Alternative hypothesis 1 (HA1): VOR measurements

observed in 1992 are greater than VOR measurements recorded in 2000;

Alternate hypothesis 2 (HA2): VOR measurements

observed in 1992 are less than VOR measurements recorded in 2000.

REGIONAL & SUB-BASIN GOALS

FUTURE OBJECTIVES AND TASKSFUTURE OBJECTIVES AND TASKS

1. INCREASE THE NUMBER OF SHARP-TAILED GROUSE TO 400 BY 2010.

Augment existing population

Monitor and control recreational use of project lands.

FUTURE OBJECTIVES AND TASKSFUTURE OBJECTIVES AND TASKS

2. Implement the SLWA Management Plan.Control introduced vegetationMaintain shrub and tree enhancementsMaintain boundary fenceConstruct new fence as neededMaintain equipment/infrastructure etc.

Maintain sharp-tailed and sage grouse nesting habitat.

FUTURE OBJECTIVES AND TASKSFUTURE OBJECTIVES AND TASKS

-Monitor leks-Search for new leks-Conduct sharp-tailed grouse nesting and brood rearing surveys

3. Conduct sharp-tailed grouse research….in conjunction with WDFW statewide efforts.

FUTURE OBJECTIVES AND TASKSFUTURE OBJECTIVES AND TASKS

4. Monitor wildlife and habitat response to protection, enhancement, and maintenance measures annually.Conduct HEP and vegetation transects and establish photo points.

Monitor big game, sage grouse, waterfowl, and neo-tropical birds populations/hunter harvest.

SUB-BASIN NEEDS AND LIMITING SUB-BASIN NEEDS AND LIMITING FACTORSFACTORSThe Swanson Lakes Wildlife Area and the Sharp-tailed Grouse Habitat Acquisition proposals address the following major sub-basin needs and limiting factors:

1. Declining shrubsteppe habitat quality and quantity and subsequent impacts on obligate species. 2. Shrubsteppe habitat fragmentation3. Loss of deep soils plant communities.4. Alteration of the plant community due to weeds, grazing, and wildfire.
