Summary

This data is to be used for riparian vegetation assessment.

Description

This layer was obtained for inclusion in BIOS from the Chico State Geographic Information Center (GIC) Website. Permission to post these data in BIOS was provided to Eric Haney (ehaney@dfg.ca.gov) by Chuck Nelson of the GIC on 9/7/2007. These data can be downloaded along with the original layer (1991 - 1998) as well as similar layers for other regions of the Central Valley from http://www.gic.csuchico.edu/Veg_sac.html . These data should be used for riparian vegetation assessment purposes only. These data are not recommended for use at the project or parcel level. This Sacramento River Riparian Mapping 1999 effort is an update to the Sacramento River Riparian Mapping Project that was started in 1991 and completed in 1998. This project, however, was confined to the mainstem of the Sacramento River between Colusa on the south and Keswick Dam to the north. It is located in the Sacramento River Conservation Area (SRCA) approximately between River Mile 129 and RM 300. The mapping was completed in 2002 using aerial photography taken in 1999 for the Sacramento River Comprehensive Study. The airphotos were flown at the nominal scale of RF=1:7200 (1"=600'). The project was funded by three agencies with a services match from the Geographical Information Center at California State University, Chico. Funding agencies included the California Department of Water Resources-Northern District Office, the California Wildlife Conservation Board, and The Nature Conservancy's Sacramento River Division. Polygons were heads-up digitized on-screen in ArcView from ortho-rectified true color scans. Orthorectification was done using Ortho Engine software, version 8, developed by PCI Geomatics of Ontario, Canada.

Riparian Vegetation Class

GIC
List of values
Value Blackberry Scrub
Description Blackberry Scrub. >= 80% coverage by blackberry vegetation.


Value Great Valley Cottonwood Riparian Forest
Description Great Valley Cottonwood Riparian Forest. >= 80% Cottonwood by canopy cover - One year old or greater. CF represents the earliest successional sere. These forests are dominated by cottonwood (Populus fremontii) and one or more tree willows (Salix gooddigii variabilis, S. laevigata, and S. lasiandra are most common) California Grape(Vitis californica) is the only conspicuous vine.


Value Disturbed
Description Disturbed. This unit identifies areas that are undergoing major disturbances and are now either completely devoid of riparian vegetation or contain only small remnants of it.


Value Gravel and Sand Bars
Description Gravel and Sand Bars - These appear as open, unvegetated areas in air photos, but ground truthing reveals several annual and short-lived perennial species of sun-loving herbs, grasses and aromatic subshrubs. The vegetation coverage is less than 50%.


Value Giant Reed
Description Giant Reed. Arundo donax. Grass <8 meters. A very invasive plant that reduces and replaces native species.


Value Herbland Cover
Description Herbland Cover. Composed of annual and perennial grasses and forbs. Must be enclosed by riparian vegetation or the stream channel.


Value Valley Freshwater Marsh
Description Valley Freshwater Marsh. Valley freshwater marshes are dominated by perennial emergent monocots. Coverage may be very high, approaching 100%. Cattails (Typha spp.) or tule (Scripus spp.) usually are the dominants, often forming monotonous swards that are sparingly punctuated with additional taxa such as sedges (Carex spp.), cane (Phragmites australlis), or blue vervain (Verbena hastata).


Value Great Valley Mixed Riparian Forest
Description Great Valley Mixed Riparian Forest. In this unit neither willows nor cottonwoods dominate - also contains a mixture of more upland, later successional species that may include valley oak ( Quercus lobata) at less than 60% canopy coverage, black walnut (Juglans spp.), ash (Fraxinus latifolia), tree of heaven (Ailanthus altissima), and sycamore (Platanus racemosa).


Value Open Water
Description Open Water. This mapping unit constitutes water, either standing or moving, and does necessarily imply vegetation.


Value Great Valley Riparian Scrub
Description Great Valley Riparian Scrub. Young primary succession which includes streamside thickets dominated by one or more willows or by other fast growing shrubs and vines.


Value Tamarisk
Description Tamarisk. "Saltcedar" Tamarix chinensis. Invasive shrub found in open areas along the river. Originally introduced as an ornamental and for erosion control, Tamarisk has become an undesirable weed. Plants spread by seed and cuttings and grow rapidly.


Value Valley Oak
Description Valley Oak (Quercus lobata) >= 60% canopy cover - must be contiguous or have longest axis greater than the distance from riparian vegetation.
