Distribution Analysis of Impatiens glandulifera in Kronoberg County and a Pest Risk Map for Alvesta Municipality
(2022) In Master Thesis in Geographical Information Science GISM01 20222Dept of Physical Geography and Ecosystem Science
- Abstract
- The spread of invasive alien species poses great risks for biodiversity, human health and economies. Impatiens glandulifera, an invasive alien plant which has been listed in The European list of Invasive Alien Species of Union concern, is widely spread in Sweden. Multiple studies have been made regarding the plant’s characteristics, spread and impacts on invaded areas.
The purpose of this study is to identify areas of potential risk from invasion. For this, a distribution analysis of I. glandulifera, covering the county of Kronoberg in Sweden, is presented. The analysis has been made with Geographic Information Systems (GIS) and is based on the records of actual observations of the plant between the years 2000 and 2021. The results...

The analysis has been made with Geographic Information Systems (GIS) and is based on the records of actual observations of the plant between the years 2000 and 2021. The results indicate that observations of I. glandulifera is more commonly found in moist soil, in urban areas and close to roads and bodies of water. Soils made up by artificial fills, which are often found in urbanized areas, are also a significant indicator for the potential presence of I. glandulifera.
The result from the analysis is compared with earlier research regarding habitat and spread preferences. A weighted overlay is made to produce a pest risk map for a minor area of the county of Kronoberg, covering Alvesta Municipality. The map depicts areas where it is more probable that I. glandulifera will occur. (Less) - Popular Abstract (Swedish)
- Spridning och etablering av invasiva främmande arter har en negativ inverkan på biologisk mångfald, människors hälsa och ekonomin. Jättebalsamin (Impatiens glandulifera) är en invasiv främmande växt som finns med på EU:s lista över invasiva främmande arter och ska bekämpas i Sverige. Flera studier har gjorts angående växtens egenskaper, spridning och påverkan på invaderade områden.
Syftet med denna uppsats är att identifiera områden med potentiell risk för invasion. För detta presenteras en utbredningsanalys av jättebalsamin som täcker Kronobergs län i Sverige. Analysen har gjorts med hjälp av Geografiska Informations System (GIS) och baseras på faktiska fynd av växten mellan åren 2000 och 2021. Resultaten tyder på att fynd av...

Syftet med denna uppsats är att identifiera områden med potentiell risk för invasion. För detta presenteras en utbredningsanalys av jättebalsamin som täcker Kronobergs län i Sverige. Analysen har gjorts med hjälp av Geografiska Informations System (GIS) och baseras på faktiska fynd av växten mellan åren 2000 och 2021. Resultaten tyder på att fynd av jättebalsamin är vanligare på fuktig jord, i tätorter och i närhet till vägar och vattendrag. Jordar som består av fyllnadsmassor, vilka ofta finns i tätorter, är också en betydande indikator på fynd av jättebalsamin. Vidare jämförs resultatet från utbredningsanalysen med tidigare forskning om habitat och spridningspreferenser. Baserad på analysen och tidigare forskning genomförs en viktad överlagringsanalys med syfte att ta fram en karta med områden med potentiell risk för invasion. Denna slutgiltiga karta täcker Alvesta kommun. (Less)
