  • Évaluation De Méthodes De Lutte Aux Plantes Envahissantes En Tourbière: Les Cas De La Quenouille Et Du Roseau
    Évaluation de méthodes de lutte aux plantes envahissantes en tourbière: les cas de la quenouille et du roseau Mémoire François Messier Maîtrise en biologie végétale Maître ès sciences (M. Sc.) Québec, Canada © François Messier, 2017 Évaluation de méthodes de lutte aux plantes envahissantes en tourbière: les cas de la quenouille et du roseau Mémoire François Messier Sous la direction de : Line Rochefort, directrice de recherche Claude Lavoie, codirecteur de recherche Résumé La quenouille à feuilles larges (Typha latifolia, une plante indigène d’Amérique du Nord) et le roseau commun (Phragmites australis, haplotype M, le génotype exotique d’Eurasie) sont souvent observés dans les tourbières à sphaignes à la suite des activités d’extraction de la tourbe. L’envahissement des milieux humides par ces plantes peut nuire au rétablissement des communautés végétales typiques des tourbières et potentiellement réduire la capacité de ces écosystèmes à stocker le carbone. De plus, les graines produites en grandes quantités peuvent être responsables de la contamination de la tourbe extraite des terrains voisins. Au Québec, des populations denses de quenouille et de roseau ont été répertoriées récemment dans deux bogs de la région du Bas-Saint-Laurent autrefois utilisés pour l’extraction de la tourbe. Le but de ce projet était d’évaluer et tester des méthodes pour lutter contre la propagation de la quenouille et du roseau en tourbière. Différentes méthodes de lutte telles que la fauche des tiges, le bâchage et la revégétalisation ont été testées dans deux sites, Bois-des-Bel (BDB, une tourbière restaurée) et Saint-Alexandre-de-Kamouraska (SAK, une tourbière non restaurée).

Este situată aproape de izvoarele râului miletin, la o altitudine de circa 160 m, într-o zonă depresionară înconjurată de dealuri joase. Solul este mlăştinos (aluvionar), speciile vegetale dominante fiind: Salix, Alnus glutinosa, Populus alba, Phragmites communis, Typha etc. Dealurile învecinate sunt împădurite cu specii forestiere, dintre care predomină: Carpinus betulas, Populus tremula, Quercus petraea, Quer- cus robur, Acer platanoides, Acer campestre, Cerasus avium etc. Între anii 1985-2007 autorii au efectuat 91 acţiuni de colectare, fiind identificate un număr de 536 specii reprezentând 13,5 % din numărul speciilor de lepidoptere cunoscute din România. Se remarcă Arytrura musculus (ménétriés, 1859), specie rară de origine est-asiatică (Coreea, Japonia), considerată un relict din vechea faună preglaciară. Specia se mai găseşte în România în Delta Dunării, Dobrogea şi lunca inferioară a mureşului. Aceasta este prima comunicare entomologică pentru această interesantă zona umedă, iar pentru bogăţia şi diversitatea speciilor de lepidoptere propunem declararea zonei ca arie protejată.

Keywords: Lepidoptera, distribution, Romania Introduction Reported species have been found in the North-East of Romania, between the Prut River and the Carpathian Mountains. This area is located in the Moldavia Plain and the Suceava Plateau. The altitude varies between 50 meters on the bank of the Prut River and 600 me- ters, in the hill and plateau areas. The climate is excessive continental. The average temperatures range from 9,60 C – in Iaşi, 8,60 C – in Botoşani and 6,90 C – in Rădăuţi. The average annual rainfall varies between 517 mm/year – in Iaşi, 569 mm/year – in Botoşani and 643 mm/year – in Rădăuţi. To the East, there is a sylvosteppe vegetation and to the west it is specific to the oak and beech forests.

    Invasive Phragmites (Phragmites australis) Best Management Practices in Ontario Improving species at risk habitat through the management of invasive Phragmites Foreword These Best Management Practices (BMPs) aim to minimize the adverse impacts of invasive Phragmites (Phragmites australis) on species at risk by providing direction on the control of Phragmites in species at risk habitats in Ontario. Funding and leadership for the production of this document were provided by the Ministry of Environment, Conservation and Parks through the Species at Risk Stewardship Program. The intent of this document is to relay specific information relating to invasive plant control practices that have been recommended by leading professionals across Ontario. This document contains the most up-to-date, effective, and environmentally safe control practices known from research and experience. It complies with current provincial and federal legislation regarding pesticide usage, habitat disturbance and species at risk protection. It is subject to change as legislation is updated or new research findings emerge and is not legal advice. The timing suggested for certain activities may differ throughout Ontario and should be tailored to your region. Interested parties are advised to refer to the applicable legislation to address specific circumstances.

    Available online at www.proenvironment.ro ProEnvironment ProEnvironment 4 (2011) 383 - 388 Original Article Histosoils in Romania - Preservation and Sustainable Management Measures PĂCURAR Ioan 1*, Doina CLAPA 2, Anca SOTROPA 1, Mihai BUTA 1, Mircea DUNCA 1 1University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, M ǎnǎş tur St., No.3-5, 400372 Cluj-Napoca, Romania 2Fruit-Growing Research Institute Cluj, Cluj-Napoca, Cluj, Romania Received 12 June 2011; received and revised form 10 July 2011; accepted 2 August 2011 Available online 1 December 2011 Abstract The peatlands coverage in Romania is over 7000 ha according to Pop and of about 6000 ha according to Taylor, occupying the 34 th place in the world, which represents 0, 03% from the country’s surface. The surface covered by these ecosystems is much smaller. They are concerted in 436 deposits having a stock of over 82.500.000 m 3. According to the same author from all the peatlands 171 are eutrophical, having a surface of over 5700 ha, with a peat stock of over 55.000.000 m3, representing the largest surface and the rest of 265 are oligotrophical peats, having smaller surfaces, being concentrated in the boreal level of the spruce fur forests from the Romanian Carpathians. The largest surfaces are found in the Apuseni Mountains, in the Dornelor and Sucevei Basin, in Tara Oasului and Maramuresului, in the Calimani Mountains, the Semenic Mountains and the superior Basin of Sebes. Floristic composition found in peat ecosystems in Romania is unique, many relict species living here during the last ice age.
