This issue of Eye on Invasives focuses on opportunities for public participation during the upcoming, inaugural California Invasive Species Action Week (CISAW), to be held Saturday, August 2 through Sunday, August 10, 2104. In this issue we highlight two efforts fueled by volunteers, the work by the Mountains Restoration Trust efforts in the Santa Monica Mountains, and the several citizen science efforts organized by the Smithsonian Environmental Research Center in Tiburon (Marin County). In addition, we discuss actions you can take at home including helping to battle back populations of invasives by eating them, as well as how to insure you aren’t introducing weeds through gardening and landscaping products.87984:6https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=87984Sun, 16 Apr 2023 15:44:02 -07002014-07-29T00:00:00Fact_SheetsInvasive species fact sheet - Fact sheet for the invasive Chinese mitten crab (Eriocheir sinensis).86531:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=86531Sun, 16 Apr 2023 15:36:05 -07002014-06-01T00:00:00Fact_SheetsInvasive species fact sheet - Fact sheet for the invasive black carp (Mylopharyngodon piceus).86530:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=86530Sun, 16 Apr 2023 15:36:03 -07002014-06-01T00:00:00Fact_SheetsInvasive species fact sheet - Fact sheet for invasive species of the Lepisosteidae (Gar) family.86528:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=86528Sun, 16 Apr 2023 15:36:02 -07002014-06-01T00:00:00Fact_SheetsInvasive species fact sheet - Fact sheet for the invasive bighead carp (Hypophthalmichthys nobilis).86527:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=86527Sun, 16 Apr 2023 15:36:01 -07002014-06-01T00:00:00Fact_SheetsInvasive species fact sheet - Fact sheet for the invasive silver carp (Hypophthalmichthys molitrix).86526:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=86526Sun, 16 Apr 2023 15:35:59 -07002014-06-01T00:00:00Fact_SheetsInvasive species fact sheet - Fact sheet for the invasive species of Family Characidae (Piranhas).86499:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=86499Sun, 16 Apr 2023 15:35:57 -07002014-06-01T00:00:00Fact_SheetsInvasive species fact sheet - Fact sheet for invasive species of the Family Channidae (Snakeheads).86498:6https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=86498Sun, 16 Apr 2023 15:35:56 -07002014-06-01T00:00:00Fact_SheetsInvasive species fact sheet - Fact sheet for the invasive brown-headed cowbird (Molothrus ater).86496:7https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=86496Sun, 16 Apr 2023 15:35:54 -07002014-06-01T00:00:00Fact_SheetsInvasive species fact sheet - Fact sheet for the invasive African clawed frog (Xenopus laevis).86494:6https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=86494Sun, 16 Apr 2023 15:35:52 -07002014-06-01T00:00:00EOIEye On Invasives Newsletter - This issue of Eye on Invasives focuses on efforts by volunteers who are working to combat invasive species on a variety of fronts. 84659:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=84659Sun, 16 Apr 2023 15:25:33 -07002014-05-12T00:00:00Aquatic Invasive Species - Outreach poster to aid in identifying aquatic invasive species78036:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=78036Sun, 16 Apr 2023 14:43:08 -07002013-03-03T00:00:00EOIEye On Invasives Newsletter - This edition of "Eye On Invasives" looks at impacts of Delta Invasions.75844:9https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=75844Sun, 16 Apr 2023 14:38:18 -07002013-12-30T00:00:00EOIEye On Invasives Newsletter - The fifth edition of "Eye On Invasives" looks at problem pets that can become invasive when released into the wild.67483:10https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=67483Sun, 16 Apr 2023 13:54:40 -07002013-05-21T00:00:00SummitCA Department of Fish and Wildlife Quagga/Zebra Mussel Project Update - CA Department of Fish and Wildlife Quagga/Zebra Mussel Project Update PowerPoint Presentation presented at the May 15, 2013 Quagga/Zebra Mussel Water Agency Summit.64581:4https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=64581Sun, 16 Apr 2023 12:28:16 -07002013-04-23T00:00:00SummitQuagga and Zebra Mussel Water Agency Summit Agenda - 60705:5https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=60705Sun, 16 Apr 2023 12:25:01 -07002013-03-08T00:00:00EOIEye On Invasives Newsletter - The fourth edition of "Eye On Invasives" focuses on marine invasives and includes partner and research spotlight articles by the California State Lands Commission and the Office of Spill Prevention and Response. 55591:9https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=55591Sun, 16 Apr 2023 12:13:57 -07002012-09-24T00:00:00Aquatic Invasive Species Decontamination Protocols - The Aquatic Invasive Species Decontamination Protocols are intended to prevent the spread of AIS, including New Zealand mudsnail (Potamopyrgus antipodarum), quagga mussel (Dreissena rostriformis bugensis) and zebra mussel (Dreissena polymorpha).43333:6https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=43333Sun, 16 Apr 2023 11:40:11 -07002022-11-02T00:00:00Quagga/Zebra Mussel Project Overview - CA Department of Fish and Wildlife Quagga/Zebra Mussel Project Overview Presentation.42636:6https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=42636Sun, 16 Apr 2023 11:39:42 -07002012-02-21T00:00:00ZebraQuaggaMusselboat, watercraft cleaning for mussels - ADA compliant version of 2009 guide to boat cleaning and inspection for Quagga/Zebra mussels.

Most of these studies recognized ambient calcium concentration as a key factor affecting the mussels' potential distribution (e.g. Mellina & Rasmussen 1994; O'Neill 1996), and based their assessments in part on estimates of the minimum calcium concentration needed to support a reproducing population, which we refer to as the mussels' "calcium threshold." Curiously, studies based on either European or North American data have generally reported different calcium thresholds. In an analysis of over 500 European lakes in regions that had been occupied by zebra mussels for over 50 years, zebra mussels were found only in waters with at least 28.3 mg/l of calcium (Ramcharan et al. 1992; Padilla 1997). In 527 lakes in Belarus, zebra mussels were found only in lakes with more than 25.4 mg/l of calcium (Karatayev 1995). In North America, on the other hand, zebra mussel populations have been reported from several sites with calcium concentrations between 13 and 25 mg/l (Strayer 1996; Mellina & Rasmussen 1994; M. Hauser, pers. comm. 1997), and studies have estimated calcium thresholds as low as 8.5 mg/l (Hincks & Mackie 1997).3870:2https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=3870Sat, 17 May 2008 15:50:51 -07002001-06-01T00:00:00ZebraQuaggaMusselspecies infestation summary - Summary of quagga mussel infestation in the United States, including background information and distribution map, general biology, frequently asked questions, and decontamination protocol.3881:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=3881Sat, 17 May 2008 15:42:16 -07002007-03-25T00:00:00ZebraQuaggaMusselaquatic invasive species management - Zebra mussels, in the form of Dreissena bugensis, also known as quagga mussels, have now, for the first time, established a beachhead west of the continental divide. The significance and potential impact of this event cannot be overstated. Zebra mussels are harmful fouling organisms: they attach by the millions to submerged objects, fill and block water pipes, and clog protective screens. Zebra mussels are efficient filter feeders: they strip food from the water that is needed to sustain other aquatic life. Direct economic costs are on the order of $100 million a year in eastern North America; unquantified secondary and environmental costs could be substantially larger. Impacts in California and the West could be as great or greater than those in the East. California cities, industries and farms depend on the transport of huge quantities of water across very large distances through a complex and vulnerable system of canals, pipes, reservoirs and pumping stations. It is thus critical that aggressive, concerted efforts be undertaken immediately to eradicate, contain and monitor the zebra mussel infestation in the lower Colorado River system.3871:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=3871Sat, 17 May 2008 14:24:34 -07002007-05-01T00:00:00aquatic invasive species management - This plan proposes management actions for addressing aquatic invasive species (AIS) threats to the State of California. It focuses on the non-native algae, crabs, clams, fish, plants and other species that continue to invade California’s creeks, wetlands, rivers, bays and coastal waters. State surveys indicate that at least 607species of aquatic invaders can be found in California’s estuarine waters. These invaders cause major impacts: disrupting agriculture, shipping, water delivery, recreational and commercial fishing; undermining levees, docks and environmental restoration activities; impeding navigation and enjoyment of the state’s waterways; and damaging native habitats and the species that depend on them. As the ease of transporting organisms across the Americas and around the globe has increased, so has the rate of AIS introductions.3868:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=3868Sat, 17 May 2008 13:23:37 -07002008-01-01T00:00:00NewZealandMudsnailinvasive species prevention - New Zealand mud snails were first reported in Europe during the 1800s and in North America (Idaho) in 1987. Mud snails quickly colonize habitable waters, and they were first discovered in the Owens River in Eastern California in late 1999 and have since spread to the Mokelumne, Calaveras, and Napa rivers, as well as Rush, Hot and Putah creeks. This invasive species will likely have impacts on native species, fisheries, and aquatic ecosystems of the Sacramento-San Joaquin watershed. Unintentional transport on fishing gear and equipment, notably wading gear, is likely one of the primary vectors spreading mud snails among water bodies. In this study, a phased approach identified several chemicals and cleaning methods that could easily be used in the field, and were efficacious in removing snails from wading gear with minimal corrosiveness to the gear.3867:1https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=3867Sat, 17 May 2008 13:11:59 -07002005-05-16T00:00:00
