  1. 1. Pine production comparison : production potential of Loblolly pine (Pinus taeda) and Slash pine (Pinus elliottii) in the southeastern USA in relation to initial density and forest management

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Resource Management

    Författare :Åsa Ramberg; [2019]
    Nyckelord :Loblolly pine; Slash pine; Scots pine; management intensity; planting density;

    Sammanfattning : The southeastern (SE) United States (US) produces more industrial timber than any other region in the world. Pine plantations in the southern US have increased from 1.8 million acres (728,400 ha) in the beginning of the 1950’s to 32 million acres (13 million ha) in the beginning of the 21st century, and cover 17 % of the forest land.

  2. 2. Vinterlammsproduktion : lönar det sig?

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Klara Karlsson; [2019]
    Nyckelord :lammproduktion; vinterlamm; bidragskalkyler; lönsamhet;

    Sammanfattning : Den vanligaste formen av lammproduktion i Sverige är så kallad höstlammspro-duktion, där lammen föds på våren, betar under sommaren och slaktas på hösten. Det förekommer dock att vårfödda lamm inte hinner nå slaktmognad till hösten. LÄS MER

  3. 3. Detecting bark beetle damage with Sentinel-2 multi-temporal data in Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Shuo Yang; [2019]
    Nyckelord :Physical Geography and Ecosystem Analysis; Remote Sensing; Bark Beetle; Insect Detection; Sentinel-2; Forest Health; Maximum Likelihood; Random Forest; Spectral Signature; Vegetation Indices; Earth and Environmental Sciences;

    Sammanfattning : The European spruce bark beetle is considered as one of the most destructive forest insects to Norway spruce trees in Europe. Climate change may increase the frequency and intensity of bark beetle outbreaks. It is therefore of vital importance to detect the bark beetle outbreaks and take it under control to prevent further damages. LÄS MER
