  1. 1. Efficiency of chemical and mechanical plant protection on sites without mechanical site preparation in Scania

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Gustav Nylander; [2021]
    Nyckelord :pesticide; mechanical protection; Pine Weevil; Hylobius abietis; Black spruce beetle; Hylastes conicularius; Strophosoma capitatum; No mechanical site preparation; Norway spruce; Picea abies; Regeneration; Seedlings; Hylonox; Imprid Skog; Forester; Woodcoat; wax;

    Sammanfattning : An important part of the regeneration after clearcutting is to have a high growth and a high level of survival of the planted seedlings. A big threat to the seedlings is the pine weevil (Hylobius abietis), but the black spruce beetle (Hylastes conicularius) can cause some serious damage too, as well as Strophosoma capitatumn. LÄS MER

  3. 2. Viskadalens mekaniska plantskydd

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Caroline Bertilsson; Viktor Magnusson; [2020]
    Nyckelord :tall; vilt; betesskador;

    Sammanfattning : Klövviltet har stor inverkan på skogsbruket speciellt när det gäller viltbetning på tallskog. Som skogsägare finns det många olika insatser som kan vidtas för att motverka viltbetning och därmed reducera ekonomiska förluster i skogsbruket. LÄS MER

  4. 3. Vilken granplanta bör användas vid föryngring? : en jämförelse mellan leverantörer, planttyper och plantskydd

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Patrik Oleinikoff; [2018]
    Nyckelord :plantförsök; borrotsplanta; snytbagge;

    Sammanfattning : The purpose of this study is to compare suppliers and variation of spruce seedlings that Linköpings Skogstjänst AB often uses in the rejuvenation phase. A trial plot has been laid out in the fields where seven different plants have been compared. A comparison has also been made between the bare root seedling and containerized seedlings. LÄS MER

  5. 4. Utrustning för applicering av vax för skydd av skogsplantor mot snytbaggeangrepp

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Adam Everås; [2016]
    Nyckelord :snytbagge; mekaniska skydd; beläggningsskydd;

    Sammanfattning : For many years Pine weevil (Hylobius abietis) has been one of the most common pests for young conifer seedlings in the northern part of Europe. Chemical protection was commonly used to protect conifer seedlings. Nowadays, certification systems such as FSC and PEFC are wide spread and include rules to reduce the use of chemicals. LÄS MER

  7. 5. Nyckeltal för älg och fodertillgång på tall Pinus sylvestris och rönn Sorbus aucuparia

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Mikael Åkerblom Andersson; [2014]
    Nyckelord :älg; rönn; tall; bete; ÄBIN;

    Sammanfattning : It has been shown that moose can affect plant community composition and structure. Selective browsing with other damages of large herbivores on tree species with different tolerance to disturbance could reshape the tree layer in both managed and natural forests. Rowan Sorbus aucuparia is widely distributed throughout Sweden and Europe. LÄS MER
