Botanical, Floristic, Rare Plant Surveys
Botanical surveys are conducted to determine what plants occur in a given area.   Usually required by regulatory agencies, botanical surveys are conducted to determine which plant species are present, especially rare species, to assess potential direct and indirect impacts of a proposed project.   Botanical surveys always include identifying vascular plants, and often include identifying nonvascular plants, such as mosses, liverworts, hornworts, and lichens.
Botanical surveys are generally floristic in nature, identifying all species present, not only the dominant or rare species.   David Magney Environmental Consulting (DMEC) conducts botanical surveys to standard survey protocols developed by the California Department of Fish and Game, California Native Plant Society, and California Botanical Society.   While botanical surveys can be conducted in most areas any time of the year, most sites must be surveyed during the seasons when the majority of plants are visible and identifiable.   This means that surveys usually need to be conducted, in most areas, during the spring and summer, and consist of at least two seasonal field surveys to be considered adequate.
DMEC botanists are experts on the California flora.   Mr. Magney is the foremost expert on the flora of Ventura County, which he has been researching since the late 1970s.   DMEC has conducted numerous botanical surveys throughout the state, including project sites throughout southern California, as well as many areas in Central and Northern California.   Additionally, Mr. Magney has conducted botanical surveys in Arizona, Nevada, New Mexico, Utah, Washington, Chile, Costa Rica, and Sweden.
