The surveys were conducted from May to June, 2007 and were funded by the California Department of Fish and Game. There are four other datasets on invasive plants for this area delineating the distribution of pampas grass, Canary Island date palm, Mexican fan palm, and 12 other invasive species. The collected data represent a baseline survey of selected invasive plants within the riparian corridors of southern Orange County coastal watersheds 20070709 ground condition Complete Unknown -117.755380 -117.506328 33.692227 33.405549 ISO 19115 Topic Category biota environment None Arundo donax invasive plants weeds Arundo None Mission Viejo Salt Creek Watershed Aliso Viejo Oso Creek Watershed Prima Deshecha Watershed California Trabuco Creek Watershed Segunda Deshecha Watershed Orange County Laguna Hills Aliso Creek Watershed San Mateo Creek Watershed San Clemente Lake Forest San Juan Creek Watershed Laguna Beach San Juan Capistrano Laguna Niguel Dana Point None 2007 None This data is intended for public use and therefore shall not be sold by third parties under any circumstances.

Jason Giessow unknown Encinitas CA jgiessow@cox.net Project Manager - Jason Giessow; Technician - Jason Casanova; Field mapper - Brad Roth Version 6.2 (Build 9200) ; Esri ArcGIS 10.6.1.9270 Attributes assigned from heads-up digitizing in the office were field verified unless there were issues with access to property and/or line of sight due to other vegetation cover, structures, etc. Accuracy of the attribute "COV" has yet to be determined. Percentages were based on a combination of aerial photo interpretation in the office and visual inspection from the ground. In some cases, values may be moderately under or over-estimated again because of issues with access to property and/or line of sight due to other vegetation cover, structures, etc. No tests for logical consistency were conducted. Comprehensive surveys (both in the office and field) were conducted for arundo, pampas grass, and palms (Mexican fan and Canary Island date) within and adjacent to the riparain corridors of the select coastal watersheds. Palms and pampas purposely planted in public and private landscaping were excluded unless there were instances that occurred adjacent to riparian areas. Additional invasive species within the riparian zone were mapped during the field verification process. Positional accuracy is no better than that of the base photography used to delineate extent. Cartographic offsets may be present in the data due to the photography's scale and legibility constraints. When feature boundaries were difficult to delineate (both in the office and field), "rough" estimated boundaries were drawn. Circumstances arise when (a) These circumstances arise when line of sight is blocked due to vegetation cover, structures, terrain, etc, and/or (b) when collection occurs in steep canyons where the GPS signal was lost. These conditions may lead to positional errors greater than the estimated error value stated below. ~.5m-3m This value is a rough estimate based on a combination of the base photography resolution and the GPS unit accuracy. No further testing was performed.

A preliminary survey for arundo, pampas grass, Mexican fan palm, and Canary Island date palm was conducted in-office using heads-up digitizing in conjunction with several high-resolution aerial imagery datasets. Oblique imagery (via the Pictometry extension for ArcGIS and maps.live.com) was used as a primary resource to assist with plant identification and location. Project data was then copied onto a field tablet (Xplore ix104C3) for follow-up verification. 2006 Obliques 2004 1ft Orthos 2005 1m Orthos 2006 1ft Orthos 2006 4in Orthos Dendra Inc, LASGRWC Jason Giessow, Jason Casanova Full FGDC-compliant metadata was created. LASGRWC Jason Casanova A field mapper verified preliminary in-house surveys using a Tablet PC/GPS unit (Xplore ix104c3 with hard-mounted Xplore GPS module). The mapper used his GPS location in conjunction with high-resolution aerial imagery within ArcPad to identify and confirm locations and attribute records of the preliminary surveys. Additional invasive species found in the field were also recorded in the database. 2006 1ft Orthos Dendra, Inc.

Attribute data was checked for consistency and accuracy. Supplemental attributes were added (Investigator, watershed, version, etc.) and fields were populated. Dendra, Inc.
