| description | Young trees of European beech (Fagus sylvatica L.) and pedunculate oak (Quercus robur L.) were burned with a propane-flamer or cut with a hand-saw with the intention to study their response, in terms of survival, ability to resprout and tree vigour during the first vegetation season after disturbance.
An early burning/cutting was performed in May and a late one in July, to see if the response was different because of the time of the year. New sprouts were counted and measured twice on the early treated trees and once on those treated late. The vigour of the trees was determined through comparing the leaf-colour of the trees to a colour-scale.
In such an early stage the survival and vigour of the cut trees was hard to determine, because they may need more than one season to start resprouting. The survival of the burned beech and oak trees did not differ much during the first season, but larger trees survived to a much higher extent than thin ones. The ability to make new sprouts as well as the tree-vigour was better for the oaks than for the beeches during the first season. |

Young trees of European beech (Fagus sylvatica L.) and pedunculate oak (Quercus robur L.) were burned with a propane-flamer or cut with a hand-saw with the intention to study their response, in terms of survival, ability to resprout and tree vigour during the first vegetation season after disturbance.

Målet med studien var att se hur bränning med propanbrännare och klippning av huvudstammen påverkade överlevnad, skottskjutning och vitalitet hos unga bokar (Fagus sylvatica L.) och ekar (Quercus robur L.) under första säsongen efter behandling. Behandlingarna utfördes vid två tillfällen under vegetationssäsongen – i maj och i juli – för att se om tidpunkten hade någon betydelse för hur träden påverkades. De nya skotten räknades och mättes två gånger på de tidigt behandlade träden och en gång på de träd som behandlades sent. Vitaliteten bedömdes genom att jämföra bladfärgen med en färgskala som gick från grönt via gult till brunt. Eftersom mätningarna gjordes under första vegetationssäsongen efter behandlingarna var det svårt att avgöra överlevnadsfrekvens och vitalitet hos de avsågade träden. Möjligheten finns att träd som inte gjorde några nya skott under första vegetationssäsongen kommer att göra det i framtiden. Överlevnaden hos brända bokar och ekar skilde inte mycket mellan arterna under den första säsongen, men grövre träd visade en betydligt högre överlevnad än klenare. Förmågan att skjuta nya skott, liksom vitaliteten, var bättre hos ek än hos bok under första säsongen. SLU/Southern Swedish Forest Research Centre 2004 L3 eng swe https://stud.epsilon.slu.se/11338/ |
