The populations of cervids have been steadily increasing in recent decades. This increase has a significant impact on forest management, especially during the forest regeneration phase. To address this issue, there are various solutions, but this report will focus on the option of feeding areas and, in particular, their quality. Today, many studies focus on the quantity of available forage and pay little attention to its quality. However, this is an equally important aspect in the dietary selection of cervids. To highlight this, the report will specifically examine the case of moose in Sweden. Furthermore, after demonstrating this aspect, a study on the impact of the forest environment, such as stand composition, stand area, soil pH, light, ... on the quality of ericaceous plants will[...]

To highlight this, the report will specifically examine the case of moose in Sweden. Furthermore, after demonstrating this aspect, a study on the impact of the forest environment, such as stand composition, stand area, soil pH, light, ... on the quality of ericaceous plants will be presented. The aim of this report is to emphasize the impact of forest management on the quality of forage. Mastering this aspect could potentially help reduce the browsing of plantations.
Les populations de cervidés ne cessent d’augmenter au cours de ces dernières décennies. Cette augmentation impact considérablement la gestion forestière, particulièrement lors de la phase de régénération de la forêt. Pour pallier ce problème, il existe différentes solutions mais ce rapport se concentrera sur l’option des surfaces de gagnages et notamment sur la qualité de celles-ci. En effet, aujourd’hui, de nombreuses études s’intéresse à la quantité de fourrage disponible et très peu sur la qualité. Pourtant, c’est un aspect tout aussi important dans la sélection alimentaire des cervidés. Pour le mettre en avant, ce rapport étudiera en particulier le cas de l’élan en Suède. De plus, après avoir démontré cet aspect, une étude sur l’impact de l’environnement forestier tel que la composition du peuplement, sa surface terrière, le pH du sol, la lumière, … sur la qualité des éricacées sera présenté. Ce rapport a donc pour but de mettre en avant l’impact de la gestion forestière sur la qualité du fourrage. Aspect qui, s’il est maîtrisé, pourrait permettre de réduire l’abroutissement des plantations.
