This manuscript discusses field sampling, data analysis and comparisons of various models as predictors of wildlife occupancy for specific vegetation desired conditions, thereby fulfilling the objectives of the project.
The project demonstrated that multiple geospatial datasets and assessment methods can be used to derive indicators associated with Tahoe's healthy vegetation and hazardous fuels desired condition, even when funding is constrained.

| 07/27/2017 4:47 PM | Kiara Cuerpo-Hadsall | Objectives: The objective of this study was to help managers identify meaning indicators for upland habitat ecological condition in accordance with vegetation desired conditions identified as part of Tahoe’s Pathway planning process and per a draft “Healthy Vegetation and Hazardous Fuels Desired Condition Monitoring Plan” (Greenberg and Dobrowski 2009). The draft monitoring plan identified indicators to characterize vegetation conditions relative to desired conditions as: 1) landscape extent of forest/non-forest types, 2) forest structural class, 3) ecological condition of non-forested lands (e.g., meadows), 4) total burned area, 5) area treated in wildland urban interface that meet flame length standards, and 6) percent of private and public parcels in urban areas that meet defensible space prescription. Absent from the list of indicators was indicator(s) to assess wildlife habitat conditions. We tested the ability of the proposed vegetation indicators to also represent change in probability of wildlife occurrence within habitat. Remote sensing and insitu field sampling were proposed methods to generate indicator values and as such were reviewed to determine their implementation efficacy for monitoring program managers. |

| 07/27/2017 4:47 PM | Kiara Cuerpo-Hadsall | Findings: Efficacy of methods prescribed in the draft vegetation monitoring plan (Greenberg and Dobrowski 2009): - Through this project the following GIS data derivative products were assembled from existing sources or otherwise uniquely derived from 2010 LiDAR and WorldView 2 datasets, including: 1) Digital Elevation Model (DEM), 2) Canopy Height Model (CHM), 3) Canopy bulk density, 4) Slope, 5) Aspect, 6) Tree Stems (map of individual tree locations - attributed with a) height to crown base (HTCB), b) crown bulk density, c) dbh, d) height), 7) Tree crown map (perimeter of individual trees), 8) Canopy cover (CC), 9) Fuel model surface, 10) Tree stand boundaries, 11) Existing vegetation type, 12) Distribution of past wildfires, 13) Distribution of past fuel treatments, 14) TARI and SEZ Maps (from SEZ project), 15) Land Cover Database (the National Land Cover Database for 1992, 2001, 2006 and 2011). *** See www.fs.fed.us/PSW/partnerships/tahoescience for additional findings. |

| 07/27/2017 4:45 PM | Kiara Cuerpo-Hadsall | Management Implications: - LiDAR based change detection is accurate and useful for several indicators, including impervious surfaces and vegetation cover, but collecting and processing the information is labor intensive, expensive, and not well suited for use annually. - It is suggested that one approach to annual monitoring would be to develop algorithm based assessments of changed using more frequently available (and less expensive) imagery from a source such as Planet Labs (https://www.planet.com/data/). This data may also be used retrospectively, to be able to capture changes as far back in time as the imagery and resolution allows. When integrated with older LANDSAT imagery, this would allow the Lake Tahoe Basin to assess change as far back as 1984. - The use of multi-species approaches to inform land management can also enhance biodiversity conservation by identifying habitat conditions that support unique suites of species. Management approaches that consider the extent and distribution of habitat conditions across landscapes have the greatest likelihood of conserving and restoring biodiversity and ecosystem functions. |
