Description:
This geodatabase contains several feature classes representing a reconstruction of the historical ecological conditons of six northern San Diego County lagoons (Buena Vista Lagoon, Agua Hedionda Lagoon, Batiquitos Lagoon, San Elijo Lagoon, San Dieguito Lagoon, and Los Peñasquitos Lagoon) prior to Euro-American modification. 

This dataset integrates many sources of data describing the historical features of the estuaries.Extensive supporting information, including bibliographic references, analyses, and research methods, can be found in the accompanying report:Beller EE, Baumgarten SA, Grossinger RM, Longcore TR, Stein ED, Dark SJ, Dusterhoff SR. 2014. Northern San Diego County Lagoons Historical Ecology Investigation: Regional Patterns, Local Diversity, and Landscape Trajectories. Prepared for the State Coastal Conservancy. SFEI Publication #722, San Francisco Estuary Institute, Richmond, CA.

The report and GIS data area available at the project website: http://www.sfei.org/HE_San_Diego_Lagoons. A geographic information system was used to collect, catalog, and analyze the spatial components of the study area.

Use Constraints:
As with any map or GIS layer, confidence or certainty varies geographically due to differences in source data or methods. This geodatabase provides direct information about the certainty level of different areas and features to allow the user to intelligently assess the applicability of the data for the chosen technical question. The Interp Cert, Shape Cert, and Loc Cert fields provide information about the certainty of classification type (feature existence), size/shape, and location, rated as high, medium, or low. For more detail about methods refer to: -- Grossinger, RM, Striplen CJ, Askevold R, Brewster E, Beller EE. 2007. Historical landscape ecology of an urbanized California valley: wetlands and woodlands in the Santa Clara Valley. Landscape Ecology.:103-120. -- Technical users are strongly encouraged to read the full study report (Beller et al. 2014 – available at http://www.sfei.org/HE_San_Diego_Lagoons) to gain a stronger understanding of the strengths and limitations of the dataset. -- In no event shall the creators, custodians, or distributors of this information be liable for any damages arising out of its use (or the inability to use it). These data are not legal documents or of survey quality and are not intended to be used as such. Although extensive effort has been made to produce error-free and complete data, all geographic information has limitations due to the scale, resolution, date and interpretation of the original source materials. Users should consult available data documentation (metadata) for these particular data to determine limitations and the precision to which the data depict distance, direction, location or other geographic characteristics. Data may be subject to change without prior notification. If this data is modified, changes should be documented in a metadata record that should accompany all redistributed data. If data is transmitted or provided in any form to another user, the data must be accompanied by a copy of this disclaimer and all documentation provided with the original data set, including the full metadata record. SFEI requests that the use of these data in any map, publication, or report should cite
