Urban legends about the origins of canal grass in Panama abound, but the Smithsonian has new evidence that puts the question to rest. Canal grass is an invasive weed, native to Asia. Because its tiny seeds blow in the wind, it readily invades clearings and spreads to form impenetrable stands by budding from tillers and rhizomes. Once established, canal grass is challenging to eliminate.

In celebration of World Fisheries Day, the Manitoba government has launched a new, interactive website called Lake Information for Anglers, Agriculture and Resource Development Minister Blaine Pedersen announced today. The new, interactive website provides valuable information in an easily accessible format to assist anglers in planning their next fishing trip. The site is home to information about fishing divisions, lake contour maps, fisheries assessment summaries, aquatic invasive species and boat launches for numerous drive-to lakes in Manitoba. The new Lake Information for Anglers website can be seen at www.manitobafisheries.com.

For landscapes plagued by autumn olive or entangled in oriental bittersweet, a new website offers help identifying and managing woody invasive plants like these. WoodyInvasives.org, developed by the Woody Invasives of the Great Lakes Collaborative, contains a wealth of information about how to distinguish woody invasive species from similar beneficial plants, an interactive map showing how these species are regulated by Great Lakes jurisdictions, detailed management approaches and noninvasive woody plant ideas for gardeners and landscape designers. "We developed the WIGL Collaborative website to help people learn to identify the woody invasive plants around them and to feel empowered to start controlling them on their properties or in their favorite green places," said Clair Ryan, coordinator of the Midwest Invasive Plant Network, the organization leading the effort.
Government of Saskatchewan.
Today, Environment Minister Dustin Duncan introduced the Government of Saskatchewan’s new Aquatic Invasive Species Strategy during an address to the Saskatchewan Wildlife Federation’s (SWF) annual convention in Weyburn. The new framework is designed to help the province prevent, address and manage aquatic invasive species (AIS) threats. The ministry and the SWF are partners on the province’s AIS Task Force – which focuses on additional education and monitoring activities – along with other government agencies, conservation groups, non-government organizations and universities. "This strategy emphasizes the need for collaboration and co-ordination with provincial and federal government agencies, non-government organizations and neighbouring jurisdictions to prevent the introduction and spread of high-risk aquatic invasive species," Duncan said. The province's new AIS Strategy, as well as further information about AIS and fishing, is available online.
Institute of Marine Affairs (Trinidad and Tobago).
Citizens with an avid interest in environmental matters will be able to 'sea' their environmental reports using mobile technology. The first of its kind in Trinidad and Tobago, the Institute of Marine Affairs' new Integrated Environmental Incident Software Platform and mobile application, called the Lionfish SeaiTT, allows users to report environmental incidents with the touch of a button. The development of this mobile application was part of a 2014 Green Fund project entitled 'Control and Management of the Invasive Lionfish in Trinidad and Tobago' which aimed to raise awareness on the arrival of the marine invasive species, the lionfish, Pterios volitans, to the territorial waters around Trinidad and Tobago, and the imminent threat the species pose to domestic marine ecosystems.

Three Asian Hornets (Vespa mandarinia) were found in the Nanaimo area on Vancouver Island in mid-August. The identification has been confirmed by Canadian and international experts. This is the first time this insect has been found in British Columbia. Please report suspected Asian giant hornet sightings to the Invasive Species Council of British Columbia.

The emerald ash borer (EAB) is a highly destructive invasive beetle which attacks and kills all species of ash, but not mountain ash, which in spite of its name, is a completely different species of tree. To help prevent the spread of EAB, the movement of ash logs and firewood out of regulated areas is restricted. Report any detections outside of regulated areas to one of the CFIA's offices.

The Woody Invasives of the Great Lakes Collaborative provides information related to woody invasive species identification, distribution, impacts, regulatory status, and control and management. The collaborative has also developed recommendations on trees, shrubs and vines that gardeners and landowners can plant as alternatives to known woody invasives. The WIGL Collaborative was founded in early 2018 and is coordinated by the staff of the Midwest Invasive Plant Network (MIPN).

The Niagara Region’s Aquatic and Riparian Invasive Species Control Database (created by Lyn A. Brown as part of a Master of Sustainability thesis at Brock University) provides a baseline for the 2017/18 state of aquatic and riparian invasive management activities in the Niagara Region of Ontario. An interactive GIS map uses the database information to show where those control efforts are occurring, and users can filter points on the map by invasive species, control type, control effectiveness, or organization.
