Status: At or Somewhat Better Than Target
Trend: Little or No Change
Confidence: High

  • Relevance - This indicator tracks changes in scenic quality of specific scenic resources associated with TRPA-listed public recreation areas and bike trails, and the aesthetic condition of facilities at the recreation sites themselves. Tracking these changes is important because it provides a measure of how changes in land use and development over time affect these resources, and how the aesthetic conditions of recreation facilities affect the visual quality of the area. Today, the scenic quality of scenic resources associated with public recreation sites is very nearly the same as it was in 1993. The trend has been for little change in conditions since then. Changes that have occurred have been mostly beneficial.
  • Adopted Standards  - To secure Threshold Standard attainment, the composite score and subcomponent scores of scenic resources associated with public recreation areas and bike trails, must be at, or higher than they were in 1993 when they were first evaluated.
  • Status – As of 2011, 376 of the 382 Public Recreation Area and Bike Trails Scenic Resources (98 percent) meet the unit-specific Threshold Standard.  The overall average of aggregated status scores was = 2, resulting in a determination of “at or somewhat better than target.”
  • Trend – As of 2011, the scenic quality of scenic resources associated with public recreation sites is nearly the same as it was in 1993. The overall average of aggregated trend scores was = 0, resulting in a determination of “little or no change.” Changes that have occurred have been mostly beneficial as a result of facility improvements.

  • Confidence
    • Status - A documented, reviewed, and accepted monitoring protocol was used to guide the collection, analysis and reporting of the scenic monitoring data. It was collected according to procedures outlined in the 1982 Study Report for the Establishment of Environmental Threshold Carrying Capacities (TRPA 1982b), and Status and Trend Monitoring Report (DRAFT) for Scenic Resources in the Lake Tahoe Basin (TRPA 2010), which set forth a methodology for measuring change in scenic quality over time. The methods are consistent with those employed by the U.S. Forest Service and are considered standard practice. This equates to a “high” confidence determination for status.
    • Trends -  Basin-wide monitoring of scenic quality and scenic resources associated with public recreation areas and bike trails, occurred in 1993, and as part of the 1996, 2001, 2006, and 2011 Threshold Evaluations. Consequently, confidence in trend determination is “high.”
    •  Overall Confidence - Because there is high confidence in the determination of both status and trend, a “high” determination is assigned to the overall status and trend determination.
  • Human and Environmental Drivers - The primary drivers affecting scenic quality in the Lake Tahoe Basin are land use, land and resource management activities, and the visual/aesthetic characteristics of manmade development.
  • Monitoring Approach – Field surveys (using established protocols) are conducted every five years by a team of qualified professionals, to examine and evaluate scenic quality of scenic resources along major roadways in the Basin, the shoreline of Lake Tahoe, and at public recreation sites and bike trails. Ratings from prior evaluations are reviewed. Updated ratings are assigned as warranted, based on current conditions.
