Summary

The purpose of the classification and vegetation map is to aid in the development of a management plan for the Departments Knoxville Wildlife Area. The vegetation classification and mapping provide an inventory of habitat types, and a measure of the extent of each type on the property, for use in assessing the biological resources present and determining appropriate management strategies.

Description

The California Department of Fish and Wildlife (Department) Vegetation Classification and Mapping Program (VegCAMP) created a fine-scale vegetation classification and map of the southern addition to the Departments Knoxville Wildlife Area (WA), Napa County, California following State Vegetation Survey, Federal Geographic Data Committee (FGDC), and National Vegetation Classification (NVC) Standards (Grossman et al 1998).

The vegetation classification was derived from data collected in the field following the Combined Rapid Assessment and Relev Protocol during the periods November 1820, 2013 and April 28May 1, 2014. Vegetation polygons were drawn using heads-up manual digitizing using the 2011 Napa County 30-cm resolution color infrared (CIR) imagery as the base imagery. Supplemental imagery included National Agricultural Imagery Program (NAIP) true color and CIR 1-meter resolution data from 20092012, BING imagery, and current and historical imagery from Google Earth. The minimum mapping unit (MMU) is 1 acre, with the exception of wetland types, which have an MMU of 1/2 acre. Ponds, riparian types, and the one vernal pool on the WA that were visible on the imagery were mapped regardless of size, and streams were generally mapped if greater than 10 m wide (narrower portions may have been mapped to maintain the continuity of the streams). Mapping is to the NVC hierarchy association, alliance, or group level based on the ability of the photointerpreters to distinguish types based on all imagery available and on the field data.

Both the existing (northern) and new addition (southern) portions of the Knoxville WA were mapped in 2002 as part of the Napa County vegetation map (https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=14660). The 2002 map is at a coarse thematic resolution (alliance through macrogroup level) and vegetation in portions of the WA has changed since the 2004 Rumsey Fire, necessitating this map update. We have produced an updated version of the KWA portion of the 2002 map layer that uses the same spatial data, but added a crosswalk to the current classification and the upper levels of the current hierarchy. This map layer is included in the downloaded dataset for this map and an expanded metadata report for that crosswalk can be found at https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=164825.

Supplemental information
Field Sampling Methods Relev samples were collected from 22 vegetation stands and Rapid Assessment (RA) samples were collected from 46 vegetation stands from November 1820, 2013 and April 28May 1, 2014 following the Combined Relev and Rapid Assessment Protocol (https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18599&inline) and using the Combined Relev and Rapid Assessment form (https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18598&inline). Relevs were used for herbaceous vegetation and include the absolute cover of all species within a 100 square meter plot. Rapid assessments were used for vegetation types characterized by a cover of at least 10 percent trees or shrubs; they include the absolute cover of 1020 of the most common or characteristic species in the entire stand (i.e., a plotless sample). Reconnaissance samples were collected for 122 stands of vegetation. A subset of the Relev and Rapid Assessment data is collected during a Reconnaissance (Recon form found in Appendix C of report Vegetation Map and Classification of Knoxville Wildlife Area, Napa County (2014) (https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=164824)). A list of all plant species recorded during field data collection can be found in Appendix D of report Vegetation Map and Classification of Knoxville Wildlife Area, Napa County (2014) (https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=164824). Sample point locations were collected with GPS-enabled data recording devices and are stored in a geodatabase maintained by VegCAMP. Relev and Rapid Assessment data were entered into VegCAMPs MS Access database, which is available from VegCAMP. The Rapid Assessment and Relev data include the date of sampling, GPS location, environmental characteristics of the sampled stands (microtopography, substrate, soil texture, slope, aspect, ground surface characteristics, disturbance type and intensity), vegetation structure (tree, shrub, and herb cover and height, total vegetation cover), cover by species, site history, and the Alliance and Association. Additionally, four digital photos taken in the cardinal directions from each Relev or Rapid Assessment location are available from VegCAMP. These data and field photos can serve as a baseline for monitoring future vegetation change. The Reconnaissance data provide observational notes on stand composition and environmental attributes at specific GPS locations in the landscape, and are sometimes associated with photos. The primary use of Reconnaissance data is to aid in mapping. Vegetation Classification Methods The classification is based largely on existing vegetation types described in the Manual of California Vegetation (Sawyer et al. 2009), but includes new provisional types which are supported by Buck-Diaz et al. 2012, Evens and Kentner 2006, and this project. The Relev and RA data collected in 2013 and 2014 (68 surveys total) were used to create the vegetation and map classification for the Knoxville WA. These data were analyzed using multivariate cluster analysis, performed by PC-ORD version 6 software. The cluster analysis was based on abundance (cover values) converted to seven different classes using the following modified Braun-Blanquette (1932) cover categories: 1 equal to or less than 1 percent, 2 = 15 percent, 3 equal to or greater than 515 percent, 4 equal to or greater than 1525 percent, 5 equal to or greater than 2550 percent, 6 equal to or greater than 5075 percent, 7 equal to or greater than 75 percent. For the analysis, VegCAMP used the Sorensen distance measure and flexible beta linkage method at -0.25 (McCune and Grace 2002). Floristic data collected in 103 reconnaissance samples were used to refine and validate the final classification for the map. Naming conventions for vegetation types follow the National Vegetation Classification System (Grossman et al. 1998) and the Manual of California Vegetation, 2nd edition (Sawyer et al. 2009). An association is defined by a group of samples that has similar dominant and characteristic species in the overstory, along with other important or indicator species, which are distinctive in a particular environmental setting. A set of similar associations is grouped hierarchically to the next higher level in the classification, the alliance. Alliances can then be nested under groups, and groups nested under macrogroups. For this map, vegetation was mapped to the association level if possible, but some polygons were mapped only to alliance. The Hierarchical Field and Mapping Key used to classify the vegetation types for this project can be found in Appendix E of report Vegetation Map and Classification of Knoxville Wildlife Area, Napa County (2014) (https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=164824). Delineation Rules and Map Attributes The vegetation map was delineated according to the following rules: Minimum Mapping Unit (MMU) and minimum width: 1 acre for typical vegetation types acre for special vegetation types (e.g., localized types) No MMU for cattle ponds 10 meter width for linear features Polygon cover class breaks: 3 acre MMU for cover class break in the overstory vegetation cover (i.e., when the adjacent vegetation is of the same mapping unit, but the cover class is different) 5 acre MMU for cover class break in the understory vegetation cover Delineation: All polygons were drawn at a scale of 1:800 to 1:3500 Additional information, including a Key to Identification of All Stands of Vegetation Sampled or Encountered in the Field can be found in the metadata report, Vegetation Map and Classification of Knoxville Wildlife Area, Napa County (2014) (https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=164824). Field Verification Field verification has not yet been completed for this map, as of January 2019. Although some areas have burned since mapping was completed in 2014, the majority of the WA lands have not burned, preserving our objective to complete accuracy assessment for this map as time and funding allow. New Alliances and Associations (for 2018 BIOS) Since generating the map in 2014, some alliances and associations have changed, often expanded, and the current NVCS type does not exactly match the map class originally used. In each case below, the NVCS type is followed by the corresponding 2014 map class in parenthesis: -Allium spp. - Streptanthus spp. - Hesperolinon spp. Serpentinite Provisional Alliance (Allium falcifolium-Eriogonum spp.-Streptanthus spp. Provisional Semi-natural Stands) -Ceanothus (oliganthus, tomentosus) Alliance ("Ceanothus oliganthus Alliance") -Leymus cinereus - Leymus triticoides Alliance (Leymus triticoides Alliance) -Thermopsis californica - Bromus carinatus - Annual Brome Association (Thermopsis californica Provisional Association) -Corethrogyne filaginifolia - Eriogonum (elongatum, nudum) Alliance (Eriogonum (elongatum, nudum) Provisional Alliance) -Eschscholzia (californica) - Lupinus (nanus) Alliance (Eschscholzia (californica) Alliance) -Nassella spp. - Melica spp. (Melica (californica, torreyana) Provisional Alliance) -Nassella spp. - Melica spp. (Nassella pulchra Alliance) Additionally, the following name change of species occurred since 2014, resulting in a corresponding change in alliance name. The current NVCS name is followed in parenthesis by the map class utilized in the 2014 map: -"Hesperocyparis sargentii Alliance" ("Callitropsis sargentii Alliance") Notes on Rarity Rankings (for 2018 BIOS) The NVCS type Nassella spp. - Melica spp. Alliance has been assigned to two map classes utilized in 2014: Melica (californica, torreyana) Provisional Alliance and Nassella pulchra Alliance. The new expanded alliance is not rare, with global and state ranks of G4 and S4, respectively, yet all currently-known associations within this alliance are considered rare at this time (including those that would be closely analogous to the above original map classes). As such, please note that, while broadly taken together this type is not rare, each occurrence of this type delineated in the map would in fact be rare when individually assessed at a finer scale of classification. Several associations within this map are assumed to be rare at this time, however their exact global and state rarity rankings are yet to be determined and vetted. Please consider these types to have state ranks of S3 or lower, as per our current understanding of their distribution and/or threat impacts: -"Adenostoma fasciculatum - Heteromeles arbutifolia / Melica torreyana" -"Ceanothus oliganthus - Adenostoma fasciculatum" -"Quercus berberidifolia - Ceanothus oliganthus" -"Quercus durata - Adenostoma fasciculatum" -"Quercus lobata - Quercus wislizeni" -"Umbellularia californica - Quercus wislizeni" Rarity ranks are subject to change due to changing threats and trends and as ranking methodologies are further refined. At this time, ranks are updated using the NatureServe Conservation Status Assessments Rank Calculator Version 3.186 and the ranks for this map are current as of January 22, 2019.
