Rosario Luterpool distribution studies of 10 vernal pools on the Santa Rosa Plateau found area to be the best single predictor of species richness in each type of regression model evaluated. Area predicted most accurately in a mixed linear-curvilinear regression model (y = a + b log x). Area appear ad to reflect ecologic diversity, because multiple linear regression • mbdels provided better predictions of species richness using combinations of physical characteristics which excluded area from the regression equa- tion. In addition, species turnover was demonstrated in a a ing:Le vernal pool that was evaluated. Int-apool distribution was studied along a soil moisture oicroto graphic gradient in a single vernal pooi on Mesa de Colorado. Plant species were found to be both temporally and spatially segregated. Plant species abundances in individual sample plots are arranged• in • an approx- imate geometric series, with few species in each sample and dominance concentrated in only a few of these. ----------------------------------------, LOMA LINDA UNIVERSITY Graduate School DISTRIBUTIONAL ECOLOGY OF VEGETATION IN THE VERNAL POOLS OF THE SANTA ROSA PLATEAU, CALIFORNIA by John A.

    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

SGMA seeks to achieve sustainability, which is defined as the absence of several undesirable results, including “depletions of interconnected surface water that have significant and unreasonable adverse impacts on beneficial users of surface water” (Water Code §10721). The Nature Conservancy (TNC) is a science-based, nonprofit organization with a mission to conserve the lands and waters on which all life depends. Like humans, plants and animals often rely on groundwater for survival, which is why TNC helped develop, and is now helping to implement, SGMA. Earlier this year, we launched the Groundwater Resource Hub, which is an online resource intended to help make it easier and cheaper to address environmental requirements under SGMA. As a first step in addressing when depletions might have an adverse impact, The Nature Conservancy recommends identifying the beneficial users of surface water, which include environmental users. This is a critical step, as it is impossible to define “significant and unreasonable adverse impacts” without knowing what is being impacted. To make this easy, we are providing this letter and the accompanying documents as the best available science on the freshwater species within the boundary of your groundwater sustainability agency (GSA).

  • Appendices I Through VIII
    APPENDIX I: Standards for Ecological Classification A given terrestrial ecological system is defined as a group of plant community types that tend to co-occur within landscapes with similar ecological processes, substrates, and/or environmental gradients. A given terrestrial ecological system will typically manifest itself in a landscape at intermediate geographic scales of 10s to 1,000s of hectares and persist for 50 or more years. Ecological processes include natural disturbances such as fire and flooding. Substrates may include a variety of soil surface and bedrock features, such as shallow soils, alkaline parent materials, sandy/gravelling soils, or peatlands. Finally, environmental gradients include hydrologically defined patterns in coastal zones, arid grassland or desert areas, or montane, alpine or subalpine zones defined by climate. By plant community type, we mean a vegetation classification unit at the association or alliance level of the US National Vegetation Classification (US-NVC) (Grossman et al. 1998, Jennings et al. 2003, NatureServe 2004), or, if these are not available, other comparable vegetation units. US-NVC associations are used wherever possible to describe the component biotic communities of each terrestrial system. Ecological systems are defined using both spatial and temporal criteria that influence the grouping of associations. Associations that consistently co-occur on the landscape therefore define biotic components of each ecological system type. Our approach to ecological systems definition using US-NVC associations is similar to the biotope or habitat approach used, for example, by the EUNIS habitat classification, which explicitly links meso-scale habitat units to European Vegetation Survey alliance units (Rodwell et al. 2002).
