Band-tailed Pigeon Surveys Generalized - CDFW [ds889]

<div style='text-align:Left;'><div><div><p><span>Band-tailed Pigeons (Patagioenas fasciata) are California's only native wild pigeon. The birds in California are part of the Pacific Coast population (P. f. monilis), and inhabit montane coniferous forests and oak woodlands in the Coast Ranges and western Sierra Nevada (Keppie and Braun 2000). Though some populations appear to be resident, the species is generally considered migratory (Smith 1968). Breeding occurs in the coniferous forests of California, Oregon and Washington (Blackmon 1976; Keppie and Braun 2000; Smith 1968). These birds are characterized by slate gray to purple plumage with males having a deeper purple coloration. There is a bright white crescent on the hindneck of adults with a patch of greenish bronze iridescent patch below (Keppie and Braun 2000). A k-selected species, Band-tailed Pigeons have the lowest reproductive potential of any game bird in California (Grinnell 1913). Breeding peaks in May/ June and extends through the summer, with usually not more than 1 nesting attempt per season and a typical clutch size of 1 egg, though larger numbers of nesting attempts and eggs per clutch have been reported (Keppie and Braun 2000; Leonard 1998). Feeding is variable and dependent on fruit/mast availability. During the non-breeding season, birds are nomadic and localize to acorn masting events. Birds have been documented feeding on fresh buds in spring then moving into elderberries, cascara, madrone and other fruits. In fall and into winter, acorns are taken whole (Keppie and Braun 2000). Pacific Coast Band-tailed pigeons continue to experience long term population declines. Harvest independent population monitoring comes from the Breeding Bird Survey and the Mineral Site Survey. The Breeding Bird Survey provides evidence of a significant downward population trend of 2.0% per year over a term from 1968-2012. Mineral Site Survey results show downward trends but 9 and 5 year trend confidence intervals include zero and are therefore considered inconclusive (Sanders 2012). The Mineral Site Survey is coordinated by the USFWS and is a cooperative effort amongst California, Oregon, Washington and British Columbia (via the Canadian Wildlife Service). The survey takes advantage of the birds' habit of congregating at springs and seeps that have high levels of mineral content. Fifty sites are surveyed annually; 10 in California, 22 in Oregon, 14 in Washington and 4 in British Columbia (Sanders 2012). The results of this survey are used to index the band-tailed pigeon population at the population level. These data describe the location of the 10 sites required for the flyway survey as well as additional sites that are surveyed if possible to improve precision. Coordinates of locations are available and may be distributed upon request and written justification of need.</span></p></div></div></div>

Quarterly Water Quality Surveys - Salton Sea [ds429]

<div style='text-align:Left;'><div><div><p><span>In the spring of 2003, California Department of Fish and Game (CDFG) personnel began quarterly sampling of Salton Sea fish at fourteen stations around the sea, as the basis of a long term monitoring program. In conjunction with this effort, water quality sampling takes place at the same time and place. *Note: This dataset should be viewed with the 'Quarterly Fishery Surveys - Salton Sea [ds428]' dataset. Methods: Eleven sampling sites comprise three broad habitat types: pelagic (3 sites), near-shore (8 sites), and estuarine (3 sites). The pelagic sites are in the approximate middles of the north basin, south basin and inter-basin areas of the Sea. The near-shore sites are spaced widely apart, four each, near the west and east shores, to capture as much breadth of habitat as possible. The estuarine sites are in the body of the Sea, close enough to the mouths of the New, Alamo, and Whitewater Rivers, to be under the influence of their outflows. The three deep water (pelagic) sites were completely unproductive for gill net sampling of fish during the first year of sampling. They have subsequently been dropped from the sampling protocol. Sampling takes place during each of the putative seasons, as follows: spring- April and May; summer- July and August; fall- October and November; winter- January and February. We attempt to compress the total sampling period into as few days as possible, to the extent that the weather, equipment maintenance, and personnel scheduling constraints allow. Nets are set for a 24 hour period. At the time of each set and retrieval of nets, water temperature, conductivity, specific conductivity, dissolved oxygen and sampling depth are measured and recorded, at the approximate mid-net water depth. Measurements are made with a handheld YSI meter, Model 85. Salinity is calculated from the specific conductivity measurement using the following algorithm: Salinity = 0.013(SC2) - 0.233(SC) + 17.102</span></p></div></div></div>

River Otters - High Mountain Lakes [ds813]

<div style='text-align:Left;'><div><div><p><span>In California, River Otters (Lontra canadensis) are most commonly associated with food-rich lowland aquatic habitats where they forage primarily on fish and crustaceans. Their distribution in high-elevation montane regions of the state, areas in which fish and crayfish were absent historically, is largely unknown. We compiled occurrence records of River Otters in California from elevations &gt;1100 m, and evaluated them using evidentiary standards. Based on 126 records, we report the widespread presence of River Otters in the Klamath, southern Cascades, and Sierra Nevada mountain ranges, including at elevations exceeding 3000 m. Sixty-three percent of the records met our definition as ''verified'', and the remaining 37% were considered ''unverified''. The distribution of observations through time and habitats in which observations were made were similar between verified and unverified records. River Otter records spanned the period from 1900 to 2017, with 50% occurring between 1991 and 2010. Ninety-three percent of the water bodies with records of River Otters contained nonnative prey (fish and crayfish). Those lacking nonnative prey all supported native prey, including amphibians and reptiles. Based on records that contained River Otter foraging observations, nonnative fishes and crayfish were represented in 89% of the total accounts, and native frogs and invertebrates were represented in 22%. It remains unclear whether River Otters occurred in California's high-elevation water bodies prior to the introduction of fish and crayfish, and additional research is needed to understand the possible influence of nonnative prey in allowing River Otters to expand their distribution in these habitats.</span></p></div></div></div>
