California's Freshwater Fishes: Status and Management
California’s freshwater fishes: status and management Rebecca M. Quiñones* and Peter B. Moyle Center for Watershed Sciences, University of California at Davis, One Shields Ave, Davis, 95616, USA * correspondence to [email protected] SUMMARY Fishes in Mediterranean climates are adapted to thrive in streams with dy- namic environmental conditions such as strong seasonality in flows. Howev- er, anthropogenic threats to species viability, in combination with climate change, can alter habitats beyond native species’ environmental tolerances and may result in extirpation. Although the effects of a Mediterranean cli- mate on aquatic habitats in California have resulted in a diverse fish fauna, freshwater fishes are significantly threatened by alien species invasions, the presence of dams, and water withdrawals associated with agricultural and urban use. A long history of habitat degradation and dependence of salmonid taxa on hatchery supplementation are also contributing to the decline of fish- es in the state. These threats are exacerbated by climate change, which is also reducing suitable habitats through increases in temperatures and chang- es to flow regimes. Approximately 80% of freshwater fishes are now facing extinction in the next 100 years, unless current trends are reversed by active conservation. Here, we review threats to California freshwater fishes and update a five-tiered approach to preserve aquatic biodiversity in California, with emphasis on fish species diversity. Central to the approach are man- agement actions that address conservation at different scales, from single taxon and species assemblages to Aquatic Diversity Management Areas, wa- tersheds, and bioregions.

January 2012 ---International Rock Gardener--- January 2012
International Rock Gardener Number 25 The Scottish Rock Garden Club January 2012 ---International Rock Gardener--- January 2012 We begin the year with some “perennial favourites”: plants with lasting attraction. The late Harold Esslemont was one of the most experienced growers and exhibitors in the SRGC over a great many years and the following article was adapted from The Rock Garden journal of 1969 to showcase some plants that are as popular today as they were over forty years ago. The last cover of 2011 was of a wintry scene in the Scottish Garden of two of the IRG team so we thought we’d share this January sunset for the start of 2012. In his weekly Bulb Log Diary, now in its tenth year, Ian shares his method of taking such photos. Cover picture: January Sunset, Aberdeen. J. Ian Young ---Mountains in the Garden--- My Twelve Favourite Alpines by the late Harold Esslemont M.B.E. (adapted by M.Y.) It was the final meeting of the season of the local group. A postcard announced that two* members had been invited to show and discuss slides of their twelve favourite alpines. It appeared that I was to be one of the speakers. I forget who told me that his list of twelve favourite alpines ran to at least twenty, but I was soon to learn how right he was. My brief was twelve plants, no more, and a decision, however difficult, had to be made. The compiling of such a list is influenced by so many factors that the result may be expected to vary widely among individuals. -
Upper Neogene Stratigraphy and Tectonics of Death Valley — a Review

Bureau of Reclamation, P. O. Box 25007, D-8530, Denver, CO 80225-0007, United States Abstract New tephrochronologic, soil-stratigraphic and radiometric-dating studies over the last 10 years have generated a robust numerical stratigraphy for Upper Neogene sedimentary deposits throughout Death Valley. Critical to this improved stratigraphy are correlated or radiometrically-dated tephra beds and tuffs that range in age from N3.58 Ma to b1.1 ka. These tephra beds and tuffs establish relations among the Upper Pliocene to Middle Pleistocene sedimentary deposits at Furnace Creek basin, Nova basin, Ubehebe–Lake Rogers basin, Copper Canyon, Artists Drive, Kit Fox Hills, and Confidence Hills. New geologic formations have been described in the Confidence Hills and at Mormon Point. This new geochronology also establishes maximum and minimum ages for Quaternary alluvial fans and Lake Manly deposits. Facies associated with the tephra beds show that ~3.3 Ma the Furnace Creek basin was a northwest–southeast-trending lake flanked by alluvial fans. This paleolake extended from the Furnace Creek to Ubehebe. Based on the new stratigraphy, the Death Valley fault system can be divided into four main fault zones: the dextral, Quaternary-age Northern Death Valley fault zone; the dextral, pre-Quaternary Furnace Creek fault zone; the oblique–normal Black Mountains fault zone; and the dextral Southern Death Valley fault zone. -

2021 Magazine
July 2021 Welcome to the July 2021 edition of BADWATER® Magazine! We are AdventureCORPS®, producers of ultra-endurance sports events and adventure travel across the globe, and the force behind the BADWATER® brand. This magazine celebrates the entire world-wide Badwater® / AdventureCORPS® series of races, all the Badwater Services, Gear, Drinks, and Clothing, and what we like to call the Badwater Family and the Badwater Way of Life. Adventure is our way of life, so – after the sad and disastrous 2020 when we were not able to host any of our life-changing events – we are pleased to be fully back in action in 2021! Well, make that almost fully: Due to pandemic travel bans still in place, international participation in our USA-based events is not where we want it and that’s really unfortunate. Badwater 135 is the de facto Olympics of Ultrarunning and the 135-Mile World Championship, so we always want as many nationalities represented as possible. (The inside front cover of this magazine celebrates all sixty-one nationalities which have been represented on the Badwater 135 start line over the years.) Our new six-day stage race across Armenia – Artsakh Ultra – will have to wait yet another year to debut in 2022, two years later than planned. But it will be incredible, the ultimate stage race with six days of world-class trail running through several millennia of incredible culture and history, and across the most dramatic and awe-inspiring landscapes. This year, we are super excited to have brought two virtual races to life, first for the 31 days of January, and then for 16 days in April. -

Volume 66 Issue 1 Winter 2021
Preservation By David Blacker, Executive Director From the Director DVNHA One of the biggest highlights of visiting Death Valley National Park or Ash Meadows National Wildlife Refuge is seeing and maybe getting a photo of a desert bighorn sheep. You see the desert bighorn in our logo, a strong and majestic animal with iconic large curling horns, but your chance of seeing one of these incredible creatures is shrinking. Surprisingly the biggest reason is not climate change, but the spread of an invasive species that dominates and destroys their water sources and bullies them out of their historic range. In the economic downturn of the early 2000s, people stopped adopting burros and the Bureau of Land Management (BLM) pens filled up. A growing unchecked burro population began to grow and spread. I began to hear reports of sightings in Panamint Valley and the Nevada Triangle back in 2005. Now there are herds occupying Butte Valley, Skidoo, Wildrose, and southern areas of the park. Everywhere burros appear, the impact is predictable. First they seize control of the local water source, trampling or eating the native vegetation. Being very territorial, they use their size and aggressive nature to chase off any competition. Once burros move into a water source, bighorn sheep will not use it. Our partners at NPS are working diligently to reduce and remove invasive burros from the park. They have partnered with Peaceful Valley Donkey Rescue to roundup and adopt out burros from Death Valley. Burro numbers increase by 20-30% a year, so more than 750 burros need to be rounded up annually to stay ahead of reproduction. -

The 2,500 square miles included in the monument embrace Death Val ley itself and parts of the rough-hewn mountains that rise abruptly on all sides to guard its colorful desolation. The Amargosa River provides the only natural entrance. To the west towers the Panamint Range and to the east the Amargosas, with the Last Chance Range pinching the north and the Avawatz Mountains blocking the south. Death Valley National Monument lies in the southeastern corner of Inyo County and borders the California-Nevada boundary line. It forms the northern point of the great Mojave Desert region. Approximately 400 square miles of the floor of the valley lie below sea level, and Bad Water, 276 feet below mean tide, is the lowest point in the United States. -
Distribution of Amargosa River Pupfish (Cyprinodon Nevadensis Amargosae) in Death Valley National Park, CA

MARSH* Native Fish Lab at Marsh & Associates, LLC, 5016 South Ash Avenue, Suite 108, Tempe, AZ 85282, USA (KGH, JBL, WJG, BRK, PCM). *correspondent: [email protected] Key words: Amargosa River pupfish, Death Valley National Park, distribution, endangered species, monitoring, intermittent streams, range ________________________________________________________________________ Amargosa River pupfish (Cyprinodon nevadensis amargosae), is one of six rec- ognized subspecies of Amargosa pupfish (Miller 1948) and survives in waters embedded in a uniquely harsh environment, the arid and hot Mojave Desert (Jaeger 1957). All are endemic to the Amargosa River basin of southern California and Nevada (Moyle 2002). Differing from other spring-dwelling subspecies of Amargosa pupfish (Cyprinodon ne- vadensis), Amargosa River pupfish is riverine and the most widely distributed, the extent of which has been underrepresented prior to this study (Moyle et al. 2015). Originating on Pahute Mesa, Nye County, Nevada, the Amargosa River flows intermittently, often under- ground, south past the towns of Beatty, Shoshone, and Tecopa and through the Amargosa River Canyon before turning north into Death Valley National Park and terminating at Badwater Basin (Figure 1). Amargosa River pupfish is data deficient with a distribution range that is largely unknown. The species has been documented in Tecopa Bore near Tecopa, Inyo County, CA (Naiman 1976) and in the Amargosa River Canyon, Inyo and San Bernardino Counties, CA (Williams-Deacon et al.
