Description

Observations of dispersal from plantations of two alien conifer species, Picea sitchensis and Larix sibirica, as well as Picea abies outside its' natural range, to natural habitats as part of the project "Kartlegging av kortdistansespredning av fremmede bartrær".

Sampling Description

Study Extent

The study included 14 plantations from the following counties: Alstahaug, Brønnøy, Dønna, Leirfjord, Nesna, Vefsn and Vevelstad. Each site was visited for one day.

Sampling

All individuals of Picea sitchensis, Larix sibirica and Picea abies found outside plantations were mapped in a 500 x 500 m square with the mother plantation in the center. Other alien species were recorded when encountered.

Method steps

  1. 1. Locate appropriate study plantations 2. Outline a 500 x 500 m square around each plantation 3. Systematically map all individuals of the selected species within this square, not including individuals found within the plantation

Taxonomic Coverages

Picea sitchensis, Larix sibirica and Picea abies were systematically mapped. A few other alien plant taxa were recorded when encountered.
  1. Picea sitchensis
    rank: species
  2. Larix sibirica
    rank: species
  3. Picea abies
