Carolyn Sarah Lusk 2012 ii ABSTRACT Giant buttercup (Ranunculus acris L.) is a serious weed of dairy pastures throughout New Zealand causing substantial economic losses from lost pasture productivity. It has developed resistance to the phenoxy herbicides (MCPA and MCPB) at many sites around New Zealand, particularly in Golden Bay. Since the discovery of resistance in the 1980s, two newer herbicides from a different mode-of-action group (acetolactate synthase inhibitor, ALS), flumetsulam and thifensulfuron-methyl, have been used widely, which appeared to overcome the resistance problem. A survey of farmers in Golden Bay indicated that most have herbicide control programmes for giant buttercup based around flumetsulam but some have reported poor control with this herbicide, particularly after several years of use. The research in this thesis was undertaken to determine whether this may be due to evolved resistance. Seedling progeny from 15 populations of giant buttercup, with known spraying history, were sprayed with a range of doses of flumetsulam, thifensulfuron-methyl and MCPA (Experiment 1) to test for differences in susceptibility. The experiment revealed a large difference in susceptibility between the populations (83-100% and 58-100% mortality at the recommended rate and 2.2 times that rate of flumetsulam applied, respectively). -

Smith, Jr. Professor Emeritus of Botany Department of Biological Sciences Humboldt State Univerity Arcata, California 14 September 2018 The Redwood National and State Parks are located in Del Norte and Humboldt counties in coastal northwestern California. The national park was F E R N S established in 1968. In 1994, a cooperative agreement with the California Department of Parks and Recreation added Del Norte Coast, Prairie Creek, Athyriaceae – Lady Fern Family and Jedediah Smith Redwoods state parks to form a single administrative Athyrium filix-femina var. cyclosporum • northwestern lady fern unit. Together they comprise about 133,000 acres (540 km2), including 37 miles of coast line. Almost half of the remaining old growth redwood forests Blechnaceae – Deer Fern Family are protected in these four parks. -

The Ranunculus Acris L. Complex in Europe S
Watsonia, 8, 237-261 (1971). 237 The Ranunculus acris L. complex in Europe s. M. COLES Department ofBotany, Birmingham University ABSTRACT The geographical variation of the Ranunculus acris L. complex within Europe has been exam ined. The following taxa are recognised in this present work: Ranunculus granatensis Boiss. R. strigulosus Schur R. acris L. sensu stricto subsp. acris var. acris var. ,,;llosus (Drabble) S. M. Coles, comb. et stat. novo var. pumilus Wahlenb. subsp. borealis (Trautv.) Nyman subsp.friesanus (Jord.) Rouy & Fouc. var.friesanus var.pyrenaeus S. M. Coles, var. novo R. granatensis and R. strigulosus have a restricted distribution and are relatively uniform in appearance. R. acris sensu stricto occurs over most of Europe and is a very variable plant. The main clinal variation in R. acris is in an east-west direction. R. acris subsp. friesanus forms no part of this variational pattern although its distribution is completely overlapped by that of subsp. acris. INTRODUCTION The plants investigated in this study are those included in Ranunculus acris L. as defined by Tutin (1964). R. acris L. sensu stricto in the present study excludes R. acris subsp. granatensis (Boiss.) Nyman and subsp. strigulosus (Schur) Hyl., which are given specific status. The R. acris complex belongs to the section Ranunculus of the subgenus Ranunculus. It can be separated from most other European species of this section by having a terete pedicel, patent sepals and a glabrous receptacle. The diploid chromosome number of R. acris L. sensu stricto is 14; within the genus a basic chromosome number of 8 is more common than one of 7. -

Washington, DC 20240 The National list of Plant Species That Occur in Wetlands represents the combined efforts of many biologists over the last decade to define the wetland flora of the United States. The U.S. Fish and Wildlife Service initially developed the list in order to provide an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (FWS/OBS 79/31) to assist in the field identification of wetlands. Plant species that occur in wetlands, as used in the National List, are defined as species that have demonstrated an ability to achieve maturity and reproduce in an environment where all or portions of the soil within the root zone become, periodically or continuously, saturated or inundated during the growing season. -

Common Groundsel Senecio Vulgaris L
PNW 466 • July 1994 Common Groundsel Senecio vulgaris L. S. Aldrich-Markham C ommon groundsel, native to Europe, is now common throughout the temperate re- gions of the world. It is wide- spread in Oregon, Washington, and Idaho, but most common west of the Cascade Mountains. This weed is found in many crops, including forages, cere- als, mint, berries, and row crops, as well as in ornamentals and vegetable gardens. Groundsel is especially a problem in forage crops be- cause it is toxic to livestock. The toxins are four pyrrolizidine alkaloids, which cause irrevers- ible liver damage. Some of the same alkaloids are found in tansy ragwort (Senecio jacobea L.), but tansy ragwort also con- tains two additional alkaloids that are more toxic. Poisoning occurs most com- monly in situations where ani- mals cannot separate out the toxic plants—when they are mixed with the forage in a pas- ture, or when they are fed in hay or silage. The liver disease is chronic and progressive, re- sulting in death months later in most animals, with few or no Susan Aldrich-Markham, Extension agent, Yamhill County, Oregon State University.
