Värdefulla träd och biotoper på Kvarnbybanan - förslag till åtgärder för att upprätthålla och förbättra den biologiska mångfalden på en golfbana i Malmö

Sammanfattning: When landscape changes due to urbanization and agriculture wild nature must adapt and find new spots to colonize. A golf course is one example of such an area. In Scania many golf courses are situated on old agricultural fields, where they can contain more biodiversity than the fields they replace. In this study I mapped potential habitats for different species of flora and fauna at Kvarnby golf course in east of Malmö. I investigated the tree diversity and planned a “tree walk” with 15 selected trees. I also listed certain types of management to help the golf club raise the biodiversity in the area. Investigated parameters were vitality, age, height, diameter of stem- and tree crown, injuries and nature value, such as lichens and dead wood. In total 1741 trees were found at the golf course and the most common species were white willow (Salix alba), hazel (Corylus avellana), oak (Quercus robur), common hawthorn (Craetagus monogyna) and the black poplar (Populus nigra). The most common injuries were wounds on the stems and ash dieback. 21 % of the trees at the golf course had some kind of nature value and the diversity of trees was good. In total 8 different biotopes was found. It is preferable to let all the roughes grow as wild as possible without pesticides and fertilizers, to favour the biodiversity in the area.
