Target Audience: Professional and student botanists, biologists, arborists, and ecologists. Participants should have knowledge of basic plant terminology.

Description: This is an intensive introductory/intermediate course on riparian and wetland plant identification and ecology. It is geared towards anyone who wants or needs to improve their knowledge and skills related to riparian/wetland plants. Emphasis will be given to southern California species and habitats; however, information learned in this class will be readily applicable throughout California and elsewhere. Common and rare species will be covered. This workshop will include classroom presentations and exercises, and field excursions, primarily around the Ventura River, a dynamic free-flowing southern California river. We will spend at least half the time in the field.

Participants will learn:

  • How to identify many riparian tree and shrub species, as well as herbaceous species, by sight and by using written dichotomous keys
  • Tips to remembering the challenging willows (Salix spp.)
  • How to use identification keys
  • Plant description terminology (Latin and Greek)
  • Tools available to help identify native plants.


Registration is now open! Last day to register is May 10.

David L. Magney, President of David Magney Environmental Consulting (DMEC), is a biologist/botanist, Certified Arborist, and physical geographer with a thorough knowledge of the flora of California and over 30 years of field experience. Mr. Magney has worked on and managed a large variety of projects throughout the Pacific Southwest, including biological resource inventories, vegetation mapping and classification, wetland delineations and restoration, rare plant surveys and ecological studies, fisheries habitat assessment and mitigation design, fisheries monitoring, small mammal trapping and surveys, biological impact analysis and mitigation, and construction and mitigation monitoring. He formed DMEC in 1997 after spending 2 years with FugroWest, 6 years with Jones & Stokes Associates, and 3 years with Dames & Moore, as well as work with the Los Padres National Forest and UCSB Herbarium.

Mr. Magney earned a BA in Geography and Environmental Studies (emphasis in botany) from the University of California, Santa Barbara in 1985. He also holds an A.S. in Landscape Horticulture from Ventura College. Mr. Magney successfully completed training courses in wetland delineation (1989) and Federal wetland policy (1991) from the Wetlands Training Institute; training in the Corps of Engineers' Hydrogeomorphic Assessment Methods (HGM); and courses on hydric soils, wetland hydrology, CEQA and NEPA, Endangered Species Acts, and vernal pools. He has taught courses or given presentations on wetland impacts and mitigation, CEQA, Clean Water Act permitting, water quality, riparian and wetland plant identification, and wetland delineation methodology. Mr. Magney has authored two floras in California and presented numerous papers on vegetation and water quality, and has nearly completed a manual on the flora of Ventura County.
