- Description
- Giant sequoias (Sequoiadendron giganteum) are unique to the Sierra Nevada, where most sequoia groves are federally managed. In the southern Sierra Nevada, 68 giant sequoia groves stretch across three jurisdictions, including Sequoia and Kings Canyon National Parks (SEKI), Sequoia National Forest (SNF), and Giant Sequoia National Monument (GSNM). While giant sequoias are difficult to study, much of what we understand about them has come out of these groves. Giant sequoias are a unique and significant part of the natural heritage of the region, the country, and the world, yet their existence may be threatened by climate change. Scope of Work is to collect and analyze high-resolution hyperspectral and LiDAR (light detection and ranging) data to map the severity of drought effects on mature giant sequoia trees, assess confidence in the results using available ground data, and evaluate next steps to improve methodology and expand the study area. Collect high-resolution hyperspectral and LiDAR imagery of giant sequoia groves during drought conditions. Timing of the study will be negotiated based on when the trees are likely to be most stressed and when the flights can logistically occur. Data collection for the two study areas totaling 145,808 acres (58,323 ha) will occur for 4 days. Total coverage will ultimately be based on weather during the 4 days of data collection. During this time period, all attempts to collect high quality, cloud free data will be made. Data collection will be undertaken using an appropriate aircraft outfitted with a sensor package comprised of a high-fidelity Visible-to-Shortwave Infrared (VSWIR) imaging spectrometer, a high-resolution multi-pulse waveform LiDAR scanner, and an embedded high resolution Global Positioning System-Inertial Measurement Unit (GPS-IMU). The VSWIR records data for the 400-2500 nm wavelength region in 5 nm bands, which are later processed to 10 nm spectral data. The data will be collected from 2000 m above ground level (a.g.l.), yielding a nominal spatial resolution (ground sampling distance) of 2.0 m for hyperspectral and 1.1 m for LiDAR data. With 50% overlap between adjacent flightlines, the nominal laser spot spacing averages 4 shots per square meter. Following each data collection day, data will be downloaded and quality checks will be conducted on both the LiDAR and spectral data. All raw data will be transferred to a secure computer archive. Interested parties to this Sources Sought must submit their capabilities statement along with documented past experience of similar sized projects no later than 3pm (1500) PST on April 17, 2015. Submit documentation electronically to david_lewis@nps.gov
