    Minnesota's Top 124 Terrestrial Invasive Plants and Pests: Priorities for Research
    (2016) Minnesota Invasive Terrestrial Plants and Pests Center
    This document, “Minnesota’s Top 124 Terrestrial Invasive Plants and Pests: Priorities for Research,” describes the outcome of efforts to identify which invasive species pose the greatest threats to Minnesota’s forests, prairies, wetlands, and agriculture. This information will be used to set funding priorities for the Minnesota Invasive Terrestrial Plants and Pests Center (MITPPC) at the University of Minnesota. Funding needs for research on terrestrial invasive species far exceed the resources that are currently available. Thus, a fair, consistent, and transparent process to determine priorities for future research is essential. Those priorities will be reflected in regular requests for proposals. The lists in this report do not supersede agency regulatory lists or management priorities. For example, the Noxious Weed Advisory Committee has a risk assessment process to identify harmful plants that threaten the state and recommend appropriate regulatory and management actions. Existing risk assessments were consulted as the species in this prioritization were evaluated.

Among plants, eligible species are (1) Typha angustifolia; (2) Lonicera maackii, L. morrowii, L. tatarica, and L. japonica; (3) Berberis x ottawensis; (4) Centaurea stoebe ssp. micranthos and C. diffusa; (5) Tanacetum vulgare; (6) Frangula alnus and Rhamnus cathartica; (7) Phragmites australis subsp. australis; (8) Gypsophila paniculata; (9) Lupinus polyphyllus; (10) Cirsium arvense; (11) Microstegium vimineum; (12) Cotoneaster lucidus; (13) Ailanthus altissima; (14) Amaranthus palmeri; and (15) Euphorbia esula. Narrowleaf cattail, Typha angustifolia, Amur honeysuckle, Lonicera maackii, Japanese honeysuckle, L. japonica, a barberry hybrid, Berberis x ottawensis, diffuse knapweed, Centaurea diffusa, baby’s breath, Gypsophila paniculata, Japanese stiltgrass, Microstegium vimineum, large- leaved lupine, Lupinus polyphyllus, hedge cotoneaster, Cotoneaster lucidus, and tree of heaven, Ailanthus altissima were newly nominated since the previous assessment. This ranking of terrestrial invasive species threats is the most extensive regionally and to our knowledge is second only to national rankings prepared by the Animal and Plant Health Inspection Service of the US Department of Agriculture.

    Potential Causes of Declines in Minnesota’s Prairie Butterflies with a Focus on Insecticidal Control of the Soybean Aphid
    (Minnesota Invasive Terrestrial Plants and Pests Center, University of Minnesota, 2017-03-20) Runquist, Erik; Heimpel, George E.
    Minnesota is home to diverse prairie butterfly fauna, but several species have recently undergone drastic population declines. For example, 10 of the 15 butterfly species classified as Endangered, Threatened, and of Special Concern by the State of Minnesota depend exclusively on native prairies. The declines of two of these, the Dakota Skipper and the Poweshiek Skipperling, have been so precipitous that they are now exceedingly rare despite having been predictably common previously. Poweshiek Skipperling is now on the verge of global extinction. Multiple regional and local factors may have contributed to these declines, and those factors are expected to have interacted in various ways. However, a working hypothesis is that these butterfly declines are at least in part the result of insecticide drift related to management of the soybean aphid, which invaded Minnesota in 2000 and led to substantial increases in insecticide applications to soybeans. On November 15, 2016, the Minnesota Invasive Terrestrial Plants and Pests Center (MITPPC) in collaboration with the University of Minnesota Institute on the Environment held a workshop to assess hypotheses that could explain the butterfly declines. The workshop featured seven speakers from the US Fish and Wildlife Service, Minnesota Department of Natural Resources, Minnesota Zoo, University of Minnesota, and Environmental Protection Agency. The presentations, which MITPPC has posted online (http://z.umn.edu/mitppcbutterfly), focused on three themes: (i) biology and conservation status of the endangered butterflies, (ii) the possible role of soybean aphid management in affecting butterfly populations, and (iii) risk assessment and potential solutions via conservation measures. The workshop fostered collaboration between experts in prairie conservation and agricultural pest management and featured extensive discussion between participants following the presentations. Members of the conservation and agricultural communities are typically not afforded the chance to engage in conversations of this type and discussions were particularly fruitful for information sharing and relationship building. This document synthesizes the findings of the workshop and provides guidance to the MITPPC on a needed integrative research program studying the non-target consequences of invasive soybean aphid management on Minnesota’s endangered prairie butterflies. We conclude that skipper conservation will be advanced through a new research program that includes tests of the hypothesis that soybean aphid insecticides are contributing to skipper declines. Targeted research is needed to assess 1) the extent of insecticide exposure the butterflies may experience in the wild and 2) the biological consequences of those exposures using replicated controlled experiments. Ongoing drift studies conducted by the Minnesota Zoo and US Fish and Wildlife Service (see below) have provided important preliminary links to soybean aphid insecticides, but significantly more data is needed to really understand wild exposure dynamics. Controlled exposure experiments may soon be launched by Minnesota Zoo and University of Minnesota researchers, but those experiments are currently funding- and personnel-limited and cannot address the full range of needed tests. The MITPPC can play a leading role by supporting and expanding critical comprehensive research on potential non-target effects of management against an invasive pest.

    Species Distribution Model Projections for Incipient Invasive Species of Minnesota
    (2019-05-20) Briscoe Runquist, Ryan D.; Lake, Thomas; Moeller, David A.
    Invasive species are marked by rapid range expansions or dramatic population growth that negatively affects ecosystems and communities outside of their historical range (Valéry et al. 2008). Because invasive species often cause considerable economic losses, land managers and conservation scientists need tools to forecast invasion risk so that they can direct resources for prevention strategies and targeted surveillance operations (Peterson and Robins 2003; Underwood et al. 2004; Thuiller et al. 2005; Loo et al. 2007; Bradley et al. 2010). Species distribution models (SDM) use species occurrence records and environmental data to build correlative models of habitat suitability and identify key environmental variables limiting range expansion (Elith and Leathwick 2009a, b; Elith et al. 2010; Elith et al. 2011). For invasive species, SDMs can be a useful tool for identifying potential habitat requirements and environmental limitations of future range expansion (Bradley et al. 2009; Bradley et al. 2010; Elith et al. 2010; Allen and Bradley 2016). In this document, we provide detailed distribution models for eight invasive species incipient to the Upper Midwest. These species are invasive to portions of North America and were identified by the Minnesota Invasive Terrestrial Plants and Pests (MITPPC) Center as not present or incipient invasions to Minnesota with potential to have economic and natural resources impacts if they were to successfully invade Minnesota. We assess of habitat suitability for these species across the state under current climate conditions and under a range of future climate scenarios. The incipient invasive species included in this document are: Palmer Amaranth (Amaranthus palmeri); Black Swallowwort (Vincetoxicum nigrum); Common Teasel (Dipsacus fullonum); Brown Knapweed (Centaurea jacea); Dalmatian Toadflax (Linaria dalmatica); Oriental Bittersweet (Celastrus orbiculatus); Japanese Hops (Humulus japonicus); Narrowleaf Bittercress (Cardamine impatiens). Additionally, this document contains distributional information on two invasive species that have invaded Minnesota and spread rapidly, causing measurable ecological and economic damage. Both species have established populations in portions of the state that are subject to control and eradication efforts. The models contained in this document provide further information on the potential for spread and establishment throughout the state. The established and top priority species are: Wild Parsnip (Pastinaca sativa); Common Tansy (Tanacetum vulgare).
