Appendix B Natural History and Control of Nonnative Invasive Species
Appendix B: Natural History and Control of Nonnative Invasive Plants Found in Ten Northern Rocky Mountains National Parks Introduction The Invasive Plant Management Plan was written for the following ten parks (in this document, parks are referred to by the four letter acronyms in bold): the Bear Paw Battlefield-BEPA (MT, also known as Nez Perce National Historical Park); Big Hole National Battlefield-BIHO (MT); City of Rocks National Reserve-CIRO (ID); Craters of the Moon National Monument and Preserve-CRMO (ID); Fossil Butte National Monument-FOBU (WY); Golden Spike National Historic Site-GOSP (UT); Grant-Kohrs Ranch National Historic Site-GRKO (MT); Hagerman Fossil Beds National Monument-HAFO (ID); Little Bighorn Battlefield National Monument-LIBI (MT); and Minidoka National Historic Site-MIIN (ID). The following information is contained for each weed species covered in this document (1) Park presence: based on formal surveys or park representatives’ observations (2) Status: whether the plant is listed as noxious in ID, MT, UT, or WY (3) Identifying characteristics: key characteristics to aid identification, and where possible, unique features to help distinguish the weed from look-a-like species (4) Life cycle: annual, winter-annual, biennial, or perennial and season of flowering and fruit set (5) Spread: the most common method of spread and potential for long distance dispersal (6) Seeds per plant and seed longevity (when available) (7) Habitat (8) Control Options: recommendations on the effectiveness of a.

Rovněţ bych chtěl poděkovat Lence Sentenské, Evě Líznarové, Pavlovi Šebkovi a Stanovi Korenkovi za podporu a cenné rady všeho druhu. 3 ABSTRAKT Koexistence a rozdělení niky pavouků rodu Philodromus V této diplomové práci byl zkoumán mechanismus umoţňující koexistenci mezi Philodromus albidus, P. aureolus a P. cespitum. Studie probíhala na území významného krajinného prvku U Kříţe v Brně Starém Lískovci. Studované území se skládá ze třech typů biotopů: listnatý les, křoviny a monokultura švestek. Pavouci byli získáváni pomocí sklepávání. U zkoumaných druhů byly porovnávány různé dimenze niky. Prostorová nika byla zkoumána na základě mikro- aţ makrobiotopových preferencí. Trofická nika byla zkoumána na základě velikosti a typu přirozené kořisti a pomocí laboratorních experimentů potravních preferencí. Časová nika byla zkoumána na základě fenologie jednotlivých druhů. Studované druhy se lišily v prostorové a trofické nice. -

Tansy Ragwort
United States Department of Agriculture NATURAL RESOURCES CONSERVATION SERVICE Invasive Species Technical Note No. MT-24 June 2009 Ecology and Management of Tansy Ragwort (Senecio jacobaea L.) By Jim Jacobs, Invasive Species Specialist and Plant Materials Specialist NRCS, Bozeman, Montana Sharlene Sing, Research Entomologist USFS Rocky Mountain Research Station, Bozeman, Montana Figure 1. A tansy ragwort infested pasture. Photo by Eric Coombs, Oregon Department of Agriculture, available from Bugwood.org Abstract Tansy ragwort, a member of the Asteraceae taxonomic family, is a large biennial or short-lived perennial herb native to and widespread throughout Europe and Asia. Stems can grow to a height of 5.5 feet (1.75 meters), with the lower half simple and the upper half many-branched at the inflorescence. Reproductive stems produce up to 2,500 bright golden-yellow flowers. Capitula (flowerheads) arranged in 20-60 flat-topped, dense corymbs per plant are composed of ray and disc florets; both produce achenes containing a single seed. Rosettes formed of distinctive pinnately-lobed leaves attain a diameter of up to 1.5 feet (0.5 meter). First reported in Montana in 1979 in Mineral County, tansy ragwort has since spread into Flathead, Lincoln, and Sanders Counties. Soils with medium to light textures in areas receiving sufficient rainfall (34 inches or 860 millimeters/year) readily support populations of tansy ragwort. This species is a troublesome weed in decadent pastures, waste areas, clear-cuts and along roadsides. Tansy ragwort produces pyrrolizidine alkaloids - these can be lethal if ingested by cattle, horses and deer, but are less toxic to sheep and goats. -

Review of Evidence Concerning Ragwort Impacts, Ecology and Control Options
Review of evidence concerning ragwort impacts, ecology and control options Report to Defra OCTOBER 2013 Authors: Ruth Laybourn, Debbie Kessell, Naomi Jones, Simon Conyers, Caroline Hallam, Nigel Boatman Food and Environment Research Agency Sand Hutton, York, YO41 1LZ 1 2 EXECUTIVE SUMMARY Introduction Ragwort is a widespread native plant in the UK, which occurs in a range of habitats including those used for grazing livestock and hay or silage production, and is of concern because it contains pyrrolizidine alkaloids (PAs) which are toxic to livestock. Problems have occurred particularly with poisoning of horses. Ragwort is a specified weed in the Weeds Act 1959, under which land owners can be required to take all reasonable steps to prevent spread on their land and onto adjoining land. Defra have issued a Code of Practice on How to Prevent the Spread of Ragwort, which was published in 2004 (revised 2007) (Defra, 2007). In order to ensure that guidance continues to be based on the latest and best evidence, the work reported here was commissioned by Defra with the following objectives: o Review and update the evidence base on the impacts of ragwort on livestock, methods of control and the cost, benefits and impacts of control; o Investigate experience of ragwort problems, policy and control in other countries o Make suggestions relating to the Code of Practice and further research needs. Biology and ecology Studies of Ragwort ecology and distribution have shown that: Ragwort is found in a wide range of habitats but requires bare ground or disturbance to establish. Ragwort plants form a rosette in their first year and typically flower, set seed and die in the second year, though in some situations they can be longer lived. -
Pyrrolizidine Alkaloid Variation in Senecio Vulgaris Populations from Native and Invasive Ranges

Some hypotheses about the invasive mechanisms of alien invasive plants consider the plant–herbivore interaction and the role of plant defense in this interaction. For example, the ``Shift Defense Hypothesis'' (SDH) argues that introduced plants evolve higher levels of qualitative defense chemicals and decreased levels of quantitative defense, as they are released of the selective pressures from specialist herbivores but still face attack from generalists. Common groundsel (Senecio vulgaris), originating from Europe, is a cosmopolitan invasive plant in temperate regions. As in other Senecio species, S. vulgaris contains pyrrolizidine alkaloids (PAs) as characteristic qualitative defense compounds. In this study, S. vulgaris plants originating from native and invasive ranges (Europe and China, respectively) were grown under identical Submitted 14 April 2017 conditions and harvested upon flowering.
