Summary

For use in assessing existing vegetation and land use conditions in the Delta and to serve as a baseline for monitoring future change.

Description

Vegetation and land use are mapped for the approximately 725,000 acres constituting the Legal Delta portion of the Sacramento and San Joaquin River Delta area. Vegetation mapping is to sub-alliance to super-alliance level (based on the National Vegetation Classification Standard, see http://biology.usgs.gov/npsveg/nvcs.html ); land use is mapped to Anderson Level 2 classification ( see http://landcover.usgs.gov/pdf/anderson.pdf ). The map classification is based on a vegetation classification derived from field data collected in summer and fall of 2005 produced by the Vegetation Classification and Mapping Program of the Department of Fish and Game. The 2002 Stockton, Sacramento, and Delta High Resolution (1-foot) Orthoimagery and 2005 NAIP (1-meter) orthoimagery served as the base. Natural vegetation comprises approximately 17 percent of the Delta study area, 65 percent is agriculture and pasture, 10 percent is urban/other and 8 percent is open water.

Data quality report - Quantitative attribute accuracy
Measure description
Map accuracy is detailed in the report, "Sacramento-San Joaquin River Delta Vegetation and Land Use Classification and Map." 2007. Vegetation Classification and Mapping Program, Biogeographic Data Branch California Department of Fish and Game, Sacramento. In general, overall accuracy of the polygons assessed was 88.7%, while the average accuracy of 59 map classes tested for accuracy was 83.3%. 48 types met or exceeded 80% accuracy; 2 types were between 70 and 80% accurate, and 9 types fell below 70% accuracy. The nine types were: Juglans californica, Baccharis pilularis/annual grasses-herbs, Rosa californica, Cornus sericea, Crypsis, Polygonum spp. - mixed forbs, algae, and Eucalyptus. Low accuracy for algae may be due to the time beween the imagery and field work to assess accuracy. Vegetation type attribution may be more accurate in the area covered by the 1-foot GSD (2002) orthoimagery than in the area covered by the 1-meter GSD (2005). Similarly, "attribution resolution" may be greater in the area covered by the 2002 imagery, that is, the photointerpreters may have been able to attribute to a finer scale (association level vs. alliance or super-alliance level) with the higher resolution imagery. However, VegCAMP did not test these differences in the map accuracy assessment. Additionally, vegetation type and cover may have changed between the imagery and map publication dates.

Measure description
Polygons were delineated using heads-up digitizing via ArcINFO onto the Stockton, Delta, and Sacramento High Resolution Orthoimagery flown at 1-foot ground sample distance (GSD) rectified to National Mapping Standards at 1:12,000 scale for most of the mapping area, and onto National Agricultural Imagery Program (NAIP) imagery flown at a one meter GSD and rectified to the national standards at 1:24,000 scale for the balance of the mapping area (areas not covered by the higher resolution imagery). The following are the minimum mapping units (MMU) and minimum widths (MW) for the project: Land use: 2 acres MMU/25 meters MW Isolated land use: 1 acre MMU/ 10 meters MW Water: 1 acre MMU/10 meters MW Vegetation: 2 acres MMU/10 meters MW Critical vegetation types such as isolated wetlands: 1 acre MMU/10 meters MW Features were occasionally mapped below MMU or minimum width. These features were so distinct or important compared to the surroundings that omitting them would have distorted the representation of the area. Mapping Criteria Land/Water Interface Tidal fluctuations in the Delta and the gradations of signature between "open water" and "upland" necessitated guidelines for delineating the land/water interface: The following conditions were mapped as land: -Upland vegetation, agriculture, urban and vacant areas -Tidal & seasonally flooded mudflats exposed at the time of the imagery -Emergent vegetation (Temporarily to permanently flooded) - including areas that are normally designed for water such as channels & canals These conditions were mapped as water: -Open water as depicted on the baseline imagery -Submerged mudflats at the time the imagery was flown -Flooded areas as a result of levee breakage Floating & submerged (fixed or non fixed rooted) aquatic vegetation were the only types of vegetation mapped in what was coded as water in the land use layer. Occasionally these transitional elements were mapped in the opposite category (e.g., wet mudflats included with land) if doing so allowed linking below-resolution patches into a unit big enough to map. In the cases of tree canopy overhanging the shoreline, the land/water boundary was placed at the presumed location of the tree trunks. Shorelines on small islands may have been expanded outward slightly to meet MMU requirements. Streams Streams that appeared as polygons on the USGS 1:24,000 topographic maps were mapped as water polygons, even if their width tapered to less than 10 meters on the imagery. Canals/Ditches Canals and ditches were mapped as water polygons if the width of the water signature itself was greater than or equal to 10 meters, and that width continued for the majority of the length of the feature. If the width decreased to consistently less than 10 meters, a good visual break (bend, road crossing, etc.) was selected to end the water polygon. Canals and ditches were not delineated as polygons where the width of the water signature was less than 10 meters, even if the berm-to-berm width was greater than 10 meters. A corridor consisting of two or more narrow (<10 meter) ditches and measuring more than 25 meters wide overall was mapped in land use as a Transportation, Communications, and Utilities polygon. Such a polygon was also mapped if the disturbance alongside a single narrow canal or ditch measured 25 meters or more in width. The delineations were made on the outside edges of the disturbance on either side of the corridor. The water in the canals or ditches was not pulled out separately. If the corridor of "ditch/canal-related disturbance" measured less than 25 meters in width, the corridor was not mapped. In ditch corridors as described above, occasionally the water in a ditch widened to 10 meters or more. For continuity, the entire length of the corridor was mapped as a Transportation, Communication, and Utilities polygon. The water was not pulled out separately. Linear Vegetation Features Natural vegetation often occurred along narrow canals and ditches. The total width between the outside edges of the vegetation on either side of the feature sometimes exceeded 10 meters. In these situations, a vegetation polygon was drafted only if the vegetation on one side of the ditch bank was wider than 10 meters, and the entire polygon was larger than one acre. Such a polygon would include vegetation on both sides of the ditch. A vegetation polygon was not pulled out if the vegetation on each bank measured less than 10 meters wide. Windrows were not mapped unless the width of the canopy met or exceeded 10 meters. Trees flanking either side of a narrow road or stream were collected as one vegetation polygon where the canopy width met or exceeded 10 meters. Although normally road centerlines were used to separate land use types, exceptions sometimes occurred where trees were involved. For instance, there were cases where a large area of trees occurred on one side of a road, and a narrow (<10 meter) strip of trees occurred on the other side of the road, which was in turn flanked by cropland. Rather than using the road to separate the natural vegetation from the cropland, the delineation was made on the tree/cropland interface. Land Use Boundaries Fence lines or the centerlines of roads, streams, ditches, etc. were used to separate adjacent land use types. Where these features weren't present, land use boundaries were drawn with consideration for polygons in the vegetation layer. Boundaries were drawn to avoid sliver polygons created when the land use and vegetation layers were superimposed. Conversely, some vegetation boundaries had straight portions due to land use delineations. Cropland and Pasture One challenge in land use mapping was to differentiate between fallow cropland, pasture, and vacant land in agricultural areas. Cropland and pasture were assigned land use code 2100, while vacant land received a code of 3100. The land use data from DWR and from San Joaquin County, as well as field observations, helped in separating these classes. A field was considered to be fallow cropland if it occurred in close proximity to active agriculture and had weeds and grasses growing, but also showed some evidence of recent agricultural activity. Similar fields sometimes occurred on the fringe of in-crop areas. If these fields had shrubs and tall weeds growing, they probably had not been farmed for more than five years. These fields were mapped as vacant. Livestock, fences, watering holes, barns, and other features were used to distinguish pasture. These may have been visible on the imagery or during the field check. If there weren't clear signs of pasture use, the land was mapped as vacant. Even with these rules, the best code for land that was not clearly in agricultural use was sometimes ambiguous. Fields extending more than 70 acres without being divided by fences, paths, etc. were generally coded as vacant. Rice At the outset of the project, the possibility of mapping rice as a separate agricultural class was investigated. This turned out not to be viable, as the signature of rice fields in the Delta region was too variable to map reliably. However, a class corresponding to Flooded Agriculture was added to the land use classification. Some of the polygons with this code may include rice. Orchards Active and recently abandoned orchards were mapped as orchards in land use. Long-abandoned orchards, with trees still standing or with trees removed, were collected as vacant land use. Transportation Corridor This land use class (code = 1410) was reserved for freeways and for city streets that exceeded 25 meters in width. Median vegetation was not pulled out separately. The delineations followed a visible right of way indicator (such as fence line) where present. Otherwise they followed the edge of the paved surface for freeways, or the bottom of the curb for city streets. On-ramps and off-ramps were not included.

Description
Per the data contributor, DFG's Aicha Ougzin, a new field schema was added to the latest version. This was to help crosswalk this dataset to other datasets. MAPUNIT is equal to the Vegetation Type referred to in the final report associated with this mapping classification. In addition, HEIGHT was replaced with HGTCLASS, WHRSIZE was replaced with SIZECLASS, WHR was replaced with CWHRTYPE, and WHRCODE was replaced with CWHRCODE. No other changes have been made.

Overview Description
Entity and Attribute Overview
Polygon attributes include Land Use (LU) based on Anderson Level II classification; Vegetation Type (VEG) based on a map classification derived from the vegetation classification that was derived from field sampling; a simple classification of whether the polygon is natural vegetation, agriculture/urban, or water (NATURALVEG); density (or cover) class (DENSITY) of the predominant vegetation layer (herb, shrub or tree); the California Wildlife Habitat Relationships class (WHR) as crosswalked from the mapping classification or land use classification; the modal height class of the predominant vegetation layer (HEIGHT); the CWHR size class/dbh (WHRSIZE) and whether the polygon has a high conservation value as habitat (HIGHVALUE). The land use definitions and descriptions were developed by Aerial Information Systems, Inc. as a Modified Anderson Land Use Classification. This classification uses a hierarchical system, allowing easy aggregation and disaggregation of classes for analysis or cartographic purposes. Levels are denoted by x000, xx00, and xx0x, e.g., 1000, 1200, 1271. Most uses are mapped to the second level, with some uses mapped to the third level. Similarly, vegetation types may be aggregated into greater levels of the hierarchy as denoted by x000, xx00, xxx0 (e.g., 5000, 5400, 5411, with xxxx being the finest scale, usually association level or mapping unit). For aggregation purposes, all levels of the hierarchy for both the Land Use and Vegetation fields are provided in this metadata, even though there may be no mapped polygons in the higher levels (e.g., 3000, shrublands), to provide GIS users with suggested aggregation schemes and names. Multiple coding of each polygon for both vegetation and land use allows flexibility in representing complex situations. Natural vegetation could be represented in areas mapped as "water" or "urban" in the other layers. For instance, water with large areas of floating aquatics may have been coded as "Water" in the land use layer but as Eichhornia crassipes (6110) in the vegetation layer. As another example, a park with a large stand of valley oaks could be coded as "Other Urban or Built-up Land" in land use but as Quercus lobata (2230) in vegetation. Areas of significant conservation value (HIGHVALUE) generally fell into three broad categories: 1) Riparian & wetland forests and woodlands including some gallery forests, 2) Tidally and non-tidally flooded marshlands and meadows including seasonally flooded vernal pools and alkali areas, 3) Associated upland annual grasslands generally as a connecting corridor to the above two categories. Criteria Used for determining HIGHVALUE: Total acreage: Generally, aggregations of polygons with natural cover over 15 - 20 acres were included in the assessment; except islands in large natural rivers where all polygon aggregations were included regardless of size. Area to perimeter ratios were factored in when evaluating narrow riparian zones or narrow natural vegetation strips along urban or agricultural interface. Canopy Density: Significance was assigned to denser canopies, especially when the openness of the canopy was due to disturbance related factors such as scraping or burns. Connectivity: Occasionally, less desirable polygons (such as annual herbaceous types) were included in the polygon aggregations to join special areas of concern that may have potential for restoration. Floristic Type: Valley oak gallery forests were given most priority, less natural types such as arroyo willow with mixed brambles were generally included in areas adjacent to more floristically significant stands which are of significant conservation value. Adjacent Land Use & Land Cover: Isolated stands within urban or agricultural areas or narrow strips along urban - agricultural interface were given less significance than areas surrounded by water or adjacent to natural vegetation. Stands adjacent to agriculture were given more significance than stands running through urban areas. Exotic & Invasive Vegetation: For the most part, these polygons were taken out of any aggregations, even if they represented a connection or corridor between significant stands.
