Summary

Under contract to the Marin Municipal Water district (MMWD), Aerial Information Systems, Inc. (AIS) conducted the photo interpretation of sudden oak death (SOD) affected vegetation stands for the Mt. Tamalpais Watershed Forest and Woodlands Project. The mapping study area, consists of approximately 18,986 acres, of Marin county. The floristic classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS).

Description

In 2015, under contract to the Marin Municipal Water district (MMWD), Aerial Information Systems, Inc. (AIS) conducted the photo interpretation of sudden oak death (SOD) affected vegetation stands for the Mt. Tamalpais Watershed Forest and Woodlands Project. They looked at 2014 imagery and used the 2009 remap layer to reclassify stands which had changed over the past 5 years, these stands were changed mostly due to SOD.

The mapping study area consists of approximately 18,986 acres of Marin county. Work was performed on the project in 2015 by using the 2014 imagery to mark changes in vegetation. The primary purpose of the project was to find areas where vegetation had changed because of SOD and to show where gaps were formed by fallen oak trees. There was a total of 99 mapping classes. Vegetation with field questions map class is not symbolized in the cartography.

CNPS under separate contract and in collaboration with CDFW VegCAMP developed the floristic vegetation classification used for the project. The floristic classification follows protocols compliant with the Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS).

The 2009 vegetation map was updated applying heads-up digitizing techniques using a 2014 base of 6-inch resolution, natural color imagery provided by MMWD, in conjunction with custom ArcGIS tools that AIS developed to update the existing 2009 database. Mapped polygons were assessed for change in Vegetation Type as a result of SOD.

More information can be found in the project report which is bundled with the BIOS vegetation map.

Field GlobalRank
* Alias GlobalRank
* Data type String
* Width 255
* Precision 0

Field description
The global rarity ranking of the plant community mapped (ranks are available for all California alliances, and some associations). Ranks are based on a set of criteria including the rarity of the community (extent and occupancy), the threats that the community is subject to, and any known trends in the quality, size, or quantity of stands within the state. Ranks go from G1 which is critically imperiled/has very few occurrences to G5, when a community is demonstrably secure due to broad distribution with area not subject to threats. Ranks G1-G3 are considered sensitive. See: http://www.natureserve.org/sites/default/files/publications/files/natureserveconservationstatusmethodology_jun12_0.pdf and https://wildlife.ca.gov/Data/VegCAMP/Natural-Communities Ranks are current as of the publication date or update date.

Ranks go from S1 which is critically imperiled/has very few occurrences to S5, when a community is demonstrably secure due to security globally. Ranks S1-S3 are considered sensitive.

* Alias Sensitive

Field description
Is the vegetation type considered sensitive? Y= yes, sensitive natural community. Alliances and associations with global ranks of G1-G3 state ranks of S1-S3 are considered sensitive natural communities. Additionally, if an association has not gone through the ranking process, but is estimated to be sensitive Y will be shown without a G or S rank. Ranks are current as of the publication date or update date.

Field SensitiveFlag
* Alias SensitiveFlag
* Data type String
* Width 255
* Precision 0
* Scale 0
Field description
The Sensitive Flag is a field where exceptions to what is in the ranking for an alliance or a determination for a group based on alliances are captured. For example, an alliance might be ranked as G4/S4, because it is broadly distributed in the state and covers a considerable area. However, every association within that alliance is considered sensitive because it isn't broadly distributed or is locally threatened. Such an alliance would have Sensitive = Y because everywhere the alliance is represented the association community is sensitive. States for this field include: "AllAssocOfAlliance" (described above); "AllAllianceOfGroup" (similar to AllAssocOfAlliance but used when all the alliances in the group are ranked as sensitive); "AllAssocOfMapClass" (used when the map only contains a subset of associations known in the state and all of these are sensitive); "SecondryFromSplit" (this can occur when the alliance or other community/level which was mapped was subsequently split into multiple, both sides of the split are known to be present in the map, the primary is not sensitive but the less common community/level from the split is sensitive); and "AllAssocFromRegion" (when it is known that only a subset of associations from alliance exist within the ecoregion that the map is in and all these are sensitive).
