The Rare Plant Treasure Hunt, A Growing Success

The Mojave Desert

Amber Swanson

The Rare Plant Treasure Hunt in the Mojave Desert has had many successes this season! We have found new occurrences and updated historic occurrences in the California Natural Diversity Database forover 100 rare plants, including rare cacti, poppies, monkey flowers and desert mallows. One rare plant in particular is Johnson’s pineapple cactus (Sclerocactus johnsonii). Three populations on the plant were found in an area where it had not been documented since 1941!

Our efforts are also making an impact on solar energy site decisions. In a recent field trip to a proposed solar energy site at the El Paso Alluvial Plain near Ridgecrest, volunteers created a list of the flora of the site. This list was then cited by a biologist for the California Energy Commission in his recommendation of a “no build” on this site partially due to the presence of preferred Desert Tortoise food there. 

Through our several field trips volunteers from all over California and the Western U.S. have been able to see thousands of native wildflowers in bloom and gain a greater appreciation of the desert. Throughout the spring and fall seasons this program will continue to yield data valuable for conservation and improved land stewardship.

Statewide Recap

Shannon Still 
 
The statewide Rare Plant Treasure Hunt has been a success in the few months it has been active. Throughout the summer we will be organizing treasure hunt events for groups and individuals.  To date, more than 100 people from 18 teams have been involved in searching for and updating occurrences of rare plants.

Individuals and/or groups from 22 CNPS chapters have been involved in the project. This has included individuals from 11 NGOs or agencies and 35 groups or businesses.

As of the end of April, nearly 50 updated or new occurrences have been submitted to CNDDB. However, many additional forms expected to be submitted in the coming months. So far, 25 new occurrences have been documented, and more than 20 previously-documented occurrences have been revisited.  

The Rare Plant Treasure Hunt will continue through the summer and fall so if you are still interested in becoming involved in the project then please contact us.

Desert Renewable Energy: In the Right Places

Greg Suba
 
In an effort to balance the building of industrial-sized energy projects with the conservation of intact wildland ecosystems, State and Federal agencies have begun working on a Natural Communities Conservation / Habitat Conservation Plan (NCCP/HCP) for California's desert region. Covering nearly 25 million acres, the Desert Renewable Energy Conservation Plan (DRECP), will be the largest NCCP/HCP developed to date. The DRECP's goals include:
  • identifying the covered activities and species associated with desert renewable energy projects,
  • developing quantitative conservation goals for target species (desert wildlife and plants) and ecosystem functions, and
  • identifying allowable levels of "take" for target species during the construction and implementation of renewable energy projects across California's desert lands.
Recently enacted legislation has created an in-lieu fee program that will be associated with the mitigation measures identified in the DRECP. The proposed DRECP timeline identifies a draft plan available for environmental review by the end of 2012, and a fully permitted plan completed by the end of 2013.

The map to be used as a starting point for DRECP conservation planning will be an ecoregion assessment map of the Mojave ecoregion developed by The Nature Conservancy. This map is based on the 2006 Landfire vegetation classification map for California. Identifying priority conservation areas using the Landfire map's vegetation classifications will be challenging because of the low-resolution of Landfire's dataset. CNPS and other groups are working to identify and provide high-resolution vegetation community data to agency staff as quickly as possible to improve the quality of information available to conservation planning map technicians and desert planning strategists. CNPS is advocating for both State and Federal regulatory agencies to quickly invest in completing a seamless , up-to-date, high-resolution vegetation map for the Mojave ecoregion to provide the missing vegetation information needed for conservation planning before large-scale desert wind and solar projects are sited and built.

South Coast Chapter  
Program Meeting:"Transitioning Flora of the Southern California Salt Marsh Plant Community" with Eric Zahn, Salt Marsh Botanist 
Monday, June 7, 7:30 pm
South Coast Botanic Garden, Palos Verdes Penninsula
Join local coastal ecologist and environmental educator Eric Zahn as we explore the variation, specialization, and diversity of southern California’s coastal plant communities. Due to their degradation and resulting rarity, coastal wetlands are of particular interest to botanists like Eric. His work has been focused on a distinct assemblage of plant species forming the southern California coastal salt marsh plant community, which ranges from its northern extent at Devereux Slough in Goleta (just north of UC Santa Barbara) south to Bahia de San Quentin, in Baja California. This presentation will explore in detail the often overlooked flora of Southern California salt marshes and will address the critical need to conserve the remaining wetlands that support this ecosystem as well as highlight local efforts focused on the research and restoration of southern California salt marsh habitat at Colorado Lagoon and Los Cerritos Wetlands in Long Beach, California.

Program location: South Coast Botanic Garden

Milo Baker Chapter  
Field Trip to The Cedars
Saturday, June 5, 9:30 am
Intrigued by the April 2009 issue of Fremontia? Want to see the magnificent beauty of The Cedars? Hidden miles behind locked gates in rural northwest Sonoma County and forming the extreme headwaters of the two main branches of Austin Creek and several tributaries of Wheatfield Fork of the Gualala River, lies a huge massif of ultrmafic (serpentine) rock called The Cedars. It's 2000+ ridges are deeply eroded, forming steep canyon walls, numerous waterfalls and cascades, ephemeral, intermittent and perennial creeks, and fascinating travertine seepages and formations. Massive barrens and talus slopes alternate with old-growth Sargent cypress woodlands, forming an intricate mosaic of vegetation with 7 of its plants found nowhere else in the world, while others have their only Sonoma County populations here. Roger Raiche will lead 20 participants to explore some of this remote area. Bring lunch and water. RSVP with Cindy Tancreto for additional information on where to meet. For more information or other Milo Baker chapter events, please go here.

Sanhedrin Chapter
Field Trip to Red Mountain and Lost Valley (Cow Mountain)
Sunday, June 13, 8 am
Ukiah
Like Rickabaugh Glade, a few miles farther south in the Mayacmas, Lost Valley is an expansive open area with abundant native forbs & grasses, with a seasonal stream and a vernal-type pool. Lost Valley has been reserved by BLM and is a wonderful place to know because of its great variety of flora, and relative ease of access. Red Mt. has been less explored by local botanists but it contains a variety of soil types, including serpentine. This year presents a particularly interesting challenge to plant nerds because Roger Raiche (creator of the original Rickabaugh plant list) has just thrown out the very distinct possibility that we may be able to locate a small population of a species of Calamagrostis (Reed Grass) that he discovered there over 25 years ago, but never thought to key out. He now believes, as it was found on serpentine, that it likely was Calamagrostis ophitidis. This is a species n ot reported in the Smith & Wheeler Flora of Mendocino County. As it turns out, Kerry Heise has already located C. ophitidison a serpentine site on the Hopland Field Station, a few miles to the south, but if a population can be found on Red Mt., this would be the farthest north this taxon has ever been located by anyone. For carpooling, please meet at the CVS parking lot along Orchard Ave. in Ukiah at 8:00 am. Come prepared with sunscreen, a hat, water, lunch, hand lens, and hiking boots. For more information call Kerry (462-4533)  or Vishnu (467-1341).
