For the IOS it was an honour and a great privilege to hold for the third time our traditional Congress at the Desert Botanical Garden. Previous Congresses were held in 1992 and 2002, and 2014 is a sig - nificant date for the Garden, as it marks the 75th Anniversary of its foundation. This Congress, like the previous ones organized at the DBG, were extremely well organized and, as always, provided an excellent opportunity for positive interaction among people interested on the study and conservation of succulent plants. As indicated in the Program reproduced here, the Congress included a keynote speaker, oral and poster presentations, exhibits of botanical art and bonsai, and a fieldtrip to the Grand Canyon. In addition, a tour to the remarkable collection of the Wallace Desert Gardens was organized. The Desert Botanical Garden and IOS are very closely related organizations because their goals are highly convergent. For several decades, both organizations have been working towards the same purpose: to advance in research and conservation of succulent plants. On behalf of the Executive Board, I would like to express our thanks and appreciation to Mr Kenneth Schutz, Executive Director of the Desert Botanical Garden, for making available to the Congress the Garden's facilities and amenities. Also, special thanks to Raul Puente, Andrew Salywon, Wendy Hodgson, Christina Carlson, and members of Garden's staff and volunteers for taking care of all the details of the organization of the Congress. Over the last few years, the IOS Board was under severe tension as a consequence of unfounded criticism of the IOS management, emitted by a member of the Board. As a result, the Board turned nearly dysfunctional during several months before the Congress and the situation caused considerable confusion among the membership. Fortunately, however, the current Board for the 2014–16 biennium has changed composition and normal conditions have already been restored for a constructive environment and positive interaction. The current IOS Board is in the best disposition to work towards the fulfilment of the substantive goals of our organization: to promote the study and conservation of succulent and allied plants and to encourage international collaboration amongst those interested in them. Due to the fact that most members of the IOS Board were not able to attend the Congress, there was not a quorum for the customary meeting of the Board. Consequently, arrangements have already been made to hold a meeting of the new Board on 26 September 2014, at the Museum of Natural History in Paris, France. Héctor M.

  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."

    "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."

    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.

    Barbed-wire Cactus Cereus tetragonus Also known as: Acanthocereus tetragonus Rating: 0.0 ( 0 votes) This description is for Barbed-wire Cactus (Cereus tetragonus): Barbed-wire Cactus. Surrounding desert prisons for years to come. Arguably, the most common cactus to have on your office desk, never mind at home, Cereus tetragonus is a dwarf and rather tender perennial, usually potted and grown under glass. Its distinctive three or five-sided stem is mid-green in colour with fine, brown spines growing from small white, hairy tufts along its edges, thus earning it its common name, the Barbed-wire Cactus. Numerous smaller stems appear over time, while the nocturnal yellow or pink blossoms are rarely seen. Though suited to pots and containers, it grows happily in gravel beds and rockeries. Water regularly when growing, but keep dry in winter and apply low-nitrogen fertilizer for extra nourishment. Find Barbed-wire Cactus in our Shop! Free shipping from € 50!

    The Natural World That I Seek out in the Desert Regions of Baja California

    The natural world that I seek out in the desert regions of Baja California and southern California provides me with scientific adventure, excitement towards botany, respect for nature, and overall feelings of peace and purpose. Jon P. Rebman, Ph.D. has been the Mary and Dallas Clark Endowed Chair/Curator of Botany at the San Diego Natural History Museum (SDNHM) since 1996. He has a Ph.D. in Botany (plant taxonomy), M.S. in Biology (floristics) and B.S. in Biology. Dr. Rebman is a plant taxonomist and conducts extensive floristic research in Baja California and in San Diego and Imperial Counties. He has over 15 years of experience in the floristics of San Diego and Imperial Counties and 21 years experience studying the plants of the Baja California peninsula. He leads various field classes and botanical expeditions each year and is actively naming new plant species from our region. His primary research interests have centered on the systematics of the Cactus family in Baja California, especially the genera Cylindropuntia (chollas) and Opuntia (prickly-pears). However, Dr. Rebman also does a lot of general floristic research and he co- published the most recent edition of the Checklist of the Vascular Plants of San Diego County. He has over 22 years of field experience with surveying and documenting plants including rare and endangered species. As a field botanist, he is a very active collector of scientific specimens with his personal collections numbering over 22,500. Since 1996, he has been providing plant specimen identification/verification for various biological consulting companies on contracts dealing with plant inventory projects and environmental assessments throughout southern California.

The primary purpose of specialist reports associated with the DEIS is to provide detailed information to assist in the preparation of the DEIS. As the DEIS was prepared, review-driven edits to the broader DEIS resulted in modifications to some of the information contained in some of the specialist reports. As a result, some reports no longer contain information and analysis that was updated through an interdisciplinary review process and is included in the DEIS in its entirety.
