Black-tailed Jackrabbit least-cost corridors for NSNF Connectivity - CDFW [ds1011]

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The northern Sierra Nevada foothills wildlife connectivity project modeled wildlife corridors for 9 focal species between 238 landscape blocks within the northern Sierra Nevada foothills and neighboring ecoregions. We followed the least-cost corridor techniques described by Beier et al. (2007). This analysis identified the least-cost corridor, or the best potential route for each species, between neighboring landscape blocks. The data needed for a least-cost corridor analysis are a resistance raster and landscape blocks. The resistance raster is the inverse of the species distribution model (SDM) output (i.e., Maxent or BioView habitat models, which rank habitat suitability across the landscape from 0-100 for each species). We identified habitat patches for each focal species within each landscape block, and connected those habitat patches using the least-cost corridor models. The least-cost corridor model does not identify barriers, risk and dispersal. We removed urban areas and areas of unsuitable/non-restorable habitat from the corridors and then inspected the corridor to make sure they were continuous. We examined the amount of predicted suitable habitat in each corridor, and measured the distance between habitat patches within each corridor to make sure it was within the maximum dispersal distance for that focal species. If the corridors did not meet these rules then habitat patches on the border of the corridor were added to meet the selection requirements.

Vegetation - Lower Feather River Update - 2018 [ds2891]

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Feather River was mapped using 2018 National Agricultural Inventory Program (NAIP) imagery, and using a classification developed by the California Native Plant Society (CNPS) based in the National Vegetation Classification System (NVCS). A report describing mapping methodology for a similar project can be found here: </SPAN><A href="https://nrm.dfg.ca.gov:443/FileHandler.ashx?DocumentID=184992" STYLE="text-decoration:underline;"><SPAN>https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=184992</SPAN></A><SPAN>. For more information about California's classification, see </SPAN><A href="https://vegetation.cnps.org:443/" STYLE="text-decoration:underline;"><SPAN>https://vegetation.cnps.org/</SPAN></A><SPAN>.Changes in a remap effort can occur due to several factors, some due to physical change and some due to non-physical change. Examples of factors that represent physical change are: stand maturation or decadence, fire, erosion, deposition, anthropogenic disturbances such as scraping/clearing, urban development, agricultural development, and restoration. Non-physical changes include: improvement in imagery quality, incorrect original mapping, imagery shifts, improvement of older linework, and change in level mapped (classification). Imagery quality continues to improve with time, which allows the photointerpreter to better determine which species are present and in what amounts to determine its best classification. A photointerpreter could also disagree with the previous mapper’s decisions and may change the classification in the remapping effort. A more subtle map change, which does not affect the acreages significantly, is when the photointerpreter improves old linework to make it better fit the classification type visually. Also, when the NAIP imagery is ortho-rectified, in some years it does not perfectly align with the year it is being compared to and linework needs to be shifted/redrawn. Lastly, a photointerpreter may have remapped an Alliance at the Group level due to lack of confidence at the Alliance level, and vice versa the interpreter may have mapped an Alliance that was previously mapped at Group level due to better confidence at that level. All of these factors should be taken into consideration when using and comparing these data to previous efforts.</SPAN></P></DIV></DIV></DIV>

Elk Home Range - Hilt - 2022-2023 [ds3174]

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The project lead for the collection of this data was Erin Zulliger. Elk (2 adult females) were captured and equipped with GPS collars (Litetrack/Pinpoint Iridium collars, Lotek Wireless Inc., Newmarket, Ontario, Canada or Vectronic Aerospace) transmitting data from 2022-2023. The Hilt herd does not migrate between traditional summer and winter seasonal ranges. Therefore, annual home ranges were modeled using year-round data to demarcate high use areas in lieu of modeling the specific winter ranges commonly seen in other ungulate analyses in California. GPS locations were fixed at 6-hour intervals in the dataset. To improve the quality of the data set, the GPS data locations fixed in 2D space and visually assessed as a bad fix by the analyst were removed.</SPAN></P><P><SPAN>The methodology used for this migration analysis allowed for the mapping of the herd’s annual range.

BBMMs were produced at a spatial resolution of 50 m using a sequential fix interval of less than 27 hours.

Bear Creek Riparian Restoration [ds2816]

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Every year since 2002, members of the BCWG have participated in the international education and outreach program, World Water Monitoring Day, by collecting basic water quality measurements at eleven locations along Bear, Ash and Lack creeks within the Bear Creek Watershed. During this once-per-year monitoring event, BCWG members observed areas with little riparian cover and high water temperatures. These high water temperatures adversely affect the aquatic ecosystems and fishery of Bear Creek. Additionally, this lack of riparian vegetation makes stream banks more susceptible to erosion and ultimately leads to increased sediment delivery to the river.</SPAN></P><P><SPAN>Building on the existing conditions documented in the Bear Creek Watershed Assessment, and the restoration goals and objectives identified in the Management Strategy, the BCWG proposes to purchase equipment to record diurnal stream temperatures, dissolved oxygen, pH, turbidity and electrical conductivity throughout the anadromous reaches of Bear Creek.

i08 FaultLines SacramentoValley

This data set is a series of polylines denoting fault lines mapped in USGS Publication MF-1790, "Geologic Map of the Late Cenozoic Deposits of the Sacramento Valley and Northern Sierran Foothills, California" (Helley and Harwood,1985). This data set was created by scanning the five- original sheets from USGS Publication MF-1790 (Helley and Harwood, 1985), the five sheets were georeferenced individually and the geologic information was digitized using AutoCAD 2006. The accuracy of the digitized lines was deemed to be within acceptable error tolerances, with the digitized lines accurately matching the original drafted lines in USGS Publication MF-1790 (Helley and Harwood, 1985). In general, the width of the contact lines on the paper copy, accounting for scale, ranged up to about 20 meters (66 feet). During the original digitization, minor topological mistakes (such as identical rock units on both sides of a lithologic contact or unclosed polygons) and omissions (such as unidentified lithologic units) were applied according to the best available knowledge. Comparisons were made between the original mylar and colorized field sheets (as available), in addition to the Geologic Map of the Battle Creek Fault Zone, Northern Sacramento Valley, California (USGS Map MF-1298, 1981), the Geologic Map of the Chico Monocline and Northeastern Part of the Sacramento Valley, California (USGS Miscellaneous Investigations Series Map I-1238, 1981), and the Geologic Map of the Red Bluff 30' X 60' Quadrangle, California (USGS Geologic Investigation Series Map I-2542, 1995). The correlation and description of geologic units were excerpted from USGS Publication MF-1790m (Helley and Harwood, 1985).
