PURPOSE To provide the Climate Action Committee and MVRD Board with five new invasive species best management practices documents for information and with an update on promotion efforts. BACKGROUND In 2018, the Climate Action Committee received reports regarding best management practices for knotweed species, giant hogweed, European fire ant, European chafer beetle, Himalayan blackberry, and Scotch broom. Those reports also identified the next set of species for which locally-tested best management practices would be most valuable, based on input from member jurisdictions on the Regional Planning Advisory Committee – Invasive Species Subcommittee: English holly, English and Irish ivies, yellow archangel, Himalayan balsam, and parrot’s feather. This report presents the best management practices for those five species and provides information about the process to develop additional best management practices. These invasive species best management practices are a Climate Action Committee Work Plan item for the second quarter of 2019. NEED FOR AND DEVELOPMENT OF REGIONAL BEST MANAGEMENT PRACTICES Invasive species are non-native flora or fauna that out-compete native species and can be highly destructive and difficult to control. They can threaten property and recreational values, infrastructure, agriculture, public health and safety, as well as ecological health. Conservation biologists globally have ranked invasive species as the second most serious threat to biodiversity, after habitat loss. At the request of member jurisdictions and other partners, the Regional Planning Advisory Committee created an Invasive Species Subcommittee in 2016 to assist with collaboration and coordination of invasive species management efforts within the region. This Subcommittee is 29778726 DĞƚƌŽsĂŶĐŽƵǀĞƌZĞŐŝŽŶĂůŝƐƚƌŝĐƚ Best Management Practices for Invasive Species: English Holly, English and Irish Ivies, Yellow Archangel, Himalayan Balsam, and Parrot’s Feather Climate Action Committee Regular Meeting Date: June 14, 2019 Page 2 of 6 composed of environment and parks staff from member jurisdictions, as well as non-voting associates from the provincial and federal government, non-profit and stewardship groups, right-of-way land managers, businesses, and staff from Metro Vancouver Regional Planning, Regional Parks and Water Services. The Invasive Species Subcommittee members raised concern about inconsistent invasive species management practices across the region and a long-standing need for locally-tested, practitioner- focussed guidance. They requested that Metro Vancouver develop regionally-appropriate best management practices for priority invasive species. In October 2018, the MVRD Board adopted the Ecological Health Framework, which illustrates Metro Vancouver's role in protecting and enhancing ecological health as it relates to its services and functions, and supporting regional efforts. The Framework commits Metro Vancouver to “develop and employ best practices in the management of invasive species on Metro Vancouver lands and promote their use region-wide”. Metro Vancouver retained the Invasive Species Council of Metro Vancouver (ISCMV), and sub- consultants Diamond Head Consulting, and the Invasive Species Council of British Columbia to create the best management practices documents. The target audiences are local government staff, crews, project managers, contractors, consultants, developers, stewardship groups, and others who have a role in invasive species management. The best management practices include guidance about identification, tracking, reporting, effective prevention and control strategies, disposal, monitoring and restoration, as well as references and additional resources. This guidance is based on the best available scientific expertise and local experience. OVERVIEW OF LATEST FIVE BEST MANAGEMENT PRACTICES (ATTACHMENTS 1-5) The best management practices for English holly (Attachment 1), English and Irish ivies (Attachment 2), yellow archangel (Attachment 3), Himalayan balsam (Attachment 4), and parrot’s feather (Attachment 5) have been reviewed by members of the RPAC-Invasive Species Subcommittee and additional local experts. Collectively, member jurisdictions on the RPAC-Invasive Species Subcommittee have spent over $660,000 annually on control and volunteer engagement related to these five invasive plants. An overview of each best management practices document is provided below. English Holly Native to Europe, northern Africa and Asia, English holly spreads both by seed and roots. It creates deep shade, modifies soil conditions, and diverts water and nutrients from other vegetation, suppressing germination of native trees and shrubs. Experts suggest that these traits make English ivy a serious threat to forest health in the Pacific Northwest. English holly infestations are also a fire hazard as the leaves can easily ignite when heated. The berries are toxic to humans, causing nausea, vomiting, abdominal pain, and diarrhea if ingested. DĞƚƌŽsĂŶĐŽƵǀĞƌZĞŐŝŽŶĂůŝƐƚƌŝĐƚ Best Management Practices for Invasive Species: English Holly, English and Irish Ivies, Yellow Archangel, Himalayan Balsam, and Parrot’s Feather Climate Action Committee Regular Meeting Date: June 14, 2019 Page 3 of 6 As stated in the best management practices, manual removal by pulling or digging is recommended, while girdling, cutting, or herbicide should be used with caution, and done by professionals who are aware of all relevant laws, including municipal pesticide bylaws. Brush cutting/mowing and prescribed burning are not generally effective, and livestock grazing is not recommended since the berries are poisonous. English and Irish Ivies English ivy and Irish ivy are native to Europe and western Asia. These ivies form dense monocultures that grow along the ground, climbing trees and structures, smothering native vegetation, and reducing biodiversity. Especially detrimental to trees, the ivy can weigh down, break branches, and cause tree failure. It also can reduce a tree’s ability to photosynthesize and spread harmful tree pathogens. The berries are toxic to humans and livestock. Ivy benefits from high carbon dioxide concentrations under warm conditions, suggesting that it will become more resilient as our climate changes. Cutting or pulling are generally the most effective control methods for ivy. This manual control is often labour intensive and, hence, ivy ‘pulls’ are often a community stewardship opportunity. Ivy on trees should be cut at chest height around the entire trunk of the tree using pruners or a saw, being careful not to cut or damage the tree bark or surface. It can then be removed from

    UNIVERSITY OF READING Delivering biodiversity and pollination services on farmland: a comparison of three wildlife- friendly farming schemes Thesis submitted for the degree of Doctor of Philosophy Centre for Agri-Environmental Research School of Agriculture, Policy and Development Chloe J. Hardman June 2016 Declaration I confirm that this is my own work and the use of all material from other sources has been properly and fully acknowledged. Chloe Hardman i Abstract Gains in food production through agricultural intensification have come at an environmental cost, including reductions in habitat diversity, species diversity and some ecosystem services. Wildlife- friendly farming schemes aim to mitigate the negative impacts of agricultural intensification. In this study, we compared the effectiveness of three schemes using four matched triplets of farms in southern England. The schemes were: i) a baseline of Entry Level Stewardship (ELS: a flexible widespread government scheme, ii) organic agriculture and iii) Conservation Grade (CG: a prescriptive, non-organic, biodiversity-focused scheme). We examined how effective the schemes were in supporting habitat diversity, species diversity, floral resources, pollinators and pollination services. Farms in CG and organic schemes supported higher habitat diversity than farms only in ELS. Plant and butterfly species richness were significantly higher on organic farms and butterfly species richness was marginally higher on CG farms compared to farms in ELS. The species richness of plants, butterflies, solitary bees and birds in winter was significantly correlated with local habitat diversity. Organic farms supported more evenly distributed floral resources and higher nectar densities compared to farms in CG or ELS. Compared to maximum estimates of pollen demand from six bee species, only organic farms supplied sufficient pollen in late summer.

Their larvae (white grubs) are below-ground pests of turfgrass, corn, and other agricultural crops. In some regions, such as the Midwestern United States, they are among the most important pest of turfgrass, building up in high densities and consuming roots below the soil/thatch interface. Five species are known to be important pests of turfgrass in North America, including northern masked chafer, Cyclocephala borealis Arrow; southern masked chafer, Cyclocephala lurida Bland [for- http://jipm.oxfordjournals.org/ merly Cyclocephala immaculata (Olivier)]; Cyclocephala pasadenae (Casey); Cyclocephala hirta LeConte; and Cyclocephala parallela Casey.

  • White Grubs (Japanese Beetle, May/June Beetle, Masked Chafer, Green June Beetle, European Chafer, Asiatic Garden Beetle, Oriental Beetle, Black Turfgrass Ataenius)
    White Grubs (Japanese Beetle, May/June Beetle, Masked Chafer, Green June Beetle, European Chafer, Asiatic Garden Beetle, Oriental Beetle, Black Turfgrass Ataenius) There are 8 different white grubs that are commonly known to cause turfgrass plant damage. They include the Japanese beetle, May and June beetle, masked chafer, green June beetle, European chafer, Asiatic garden beetle, oriental beetle, and black turfgrass ataenius. They all do the most damage in their larval stage, although some adults can also cause damage. Japanese Beetle (Popillia japonica) Japanese beetles are concentrated mostly in the northeastern and Mid Atlantic states. The Japanese beetle larvae are the primary cause of turf damage. They feed on turfgrass roots, which causes yellowing and a wilting, thinning appearance to the plants. Turf that has been damaged can easily be rolled or lifted back from the soil because the grubs have eaten through the fibrous roots. Typical Japanese beetle raster pattern.

  • Utilisation of Pollen Resources by Bumblebees in an Enhanced Arable Landscape
    Final contract report to English Nature, Project VT0312 22nd February 2004 Utilisation of pollen resources by bumblebees in an enhanced arable landscape Claire Carvell, Bill Meek, Richard Broughton, Tim Sparks and Richard Pywell NERC Centre for Ecology and Hydrology, Monks Wood, Abbots Ripton, Huntingdon, PE28 2LS, UK. Tel: 01487 772400 Paul Westrich Lichtensteinstr. 17, D-72127 Kusterdingen, Germany Marek Nowakowski The Farmed Environment Company, Manor Farm, Eddlethorpe, York, North Yorkshire YO17 9QT, UK Summary · Pollen is an essential resource for bumblebees, yet this is often overlooked in studies of their foraging requirements. The decline of bumblebees across the UK and rest of Europe has prompted conservation measures to consider the provision of pollen as well as nectar resources, particularly in intensive agricultural landscapes where the pollination service bumblebees provide is so important. · This report details a study carried out in July 2003 to investigate the utilisation of pollen from different forage plant species by two bumblebee species with contrasting ecologies (Bombus pascuorum and Bombus terrestris/lucorum) across an enhanced arable landscape. · An area of 1.96 km2, centred on Manor Farm, near Malton in North Yorkshire, was divided into grid squares of 100m x 100m. Pollen loads were sampled from foraging bumblebees in eight random squares within the centre of this grid, and every square was surveyed in detail to map the distribution and abundance of all plant species in flower. Each pollen load was analysed to identify the pollen genera and/or species present, and to estimate the percentage species composition of the load. · The two bumblebee species showed specialization towards pollen from contrasting species.
