The following pages contain the images of the Sonoran Desert Conservation Plan riparian mapping project converted from coverage files.
The riparian mapping project was developed for planning purposes.
Riparian areas were delineated and their vegetation communities described by dominant plant species for the purpose of the Sonoran Desert Conservation Plan.
These data incorporated existing riparian data from Pima County, Organ Pipe Cactus National Monument, Oro Valley, Cienega Creek Natural Preserve,
National Wetlands Inventory, and the Bureau of Reclamation, along with new inventories.
New wash delineation was based on the visual difference between upland and riparian communities,
with the assumption that riparian plant communities are denser compared to upland plant communities.
The original database was developed at 1:24,000 scale based on June 1996 USGS Digital Orthophoto Quadrangles.
Plant community designation followed Brown et al. (1979). A non-statistical assessment of plant community designation and delineation was performed by field and peer-review.
The classifications of riparian vegetation on these maps are not as detailed as the information contained in the Geographic Information System database.
The Geographic Information Services Division data shall not be copied, reproduced or used in any form by any party other than User or an agent of User and
shall not be used by any party for any commercial purpose. Use of the data as an engineering tool is expressly forbidden.
In addition to other remedies, a violation of this limitation of use may result in the assessment of penalties in accordance with A.R.S. 39-121.03.
