Marion Gosselin proposes an overview of the ecological dynamics of the forest environments, alose named ecological successions. She presents their principal steps, from the pioneer stages to the mature ones, focusing on their respective biodiversities. To finish, she draws a parallel between those natural evolutions and the current strategies of forest management.

Marion Gosselin proposes a focus on the dead wood, which is an essential component of the forests. The linked biodiversity, the saproxylic species, indeed represents 25% of the forest biodiversity. On the basis of an understanding of its functioning and of its benefits, she highlights a real preservation issue linked to this dead wood.

« Working with Nature » – Sami reindeer herders and biodiversity in the boreal forest (2016)

Produced for the ILK dialogue workshop (11-13 January 2016, UNESCO Headquarters, Paris) organized within the framework of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES), this film presents extracts from interviews with three reindeer herders from the Sami community of Sirges in Jokkmokk, Sweden. The herders attest to the importance of biological diversity for their herding livelihood and their dependence on the health of the boreal forest ecosystem. They describe the practices that threaten herding along with the remaining stands of old forest, and their conflicts notably with industrial forestry. Expressed in other terms, they analyze the ecosystem services provided by the biodiversity of their subarctic forest milieu, and confirm that any threat to the biodiversity upon which they and their herds depend, is a threat to their way of life.

Continental biodiversity: rivers and forests - Introduction

/ Université Paris I Panthéon-Sorbonne, UVED / Canal-u.fr
Voir le résumé
Voir le résumé
In this third part, you will discover the biodiversity of the terrestrial and continental aquatic environments. Those environments are extremely diversified and are subjected to very specific dynamics, like intermittent rivers or ecological successions of the forest environments. Some of those environments present important physicochemical variations, like the rivers, from the spring to the estuary. The biodiversity is very rich in those environments, and several preservation prospects are presented.
