Wild ungulates as dynamic actors of contemporaneous social-ecological systems - a case study in Chambord World Heritage Site, France
Résumé
Chambord is a World Heritage Site since 1981, and is famous for his Renaissance Castle, his wooded and walled park, the hunting practice and the red deer Cervus elaphus, its iconic animal. Chambord has for a long time contributed to the reintroduction of red deer in many French and European forests and is now place of a long-term research program on the efficiency of hunting on red deer population dynamics.
Within the Costaud project “Contribution of wild ungulates to ecosystem functioning and services rendered in Chambord”, we have the goal to improve the comprehension and to initiate a renewed reading of Chambord landscapes by an interdisciplinary and integrated approach of the wild ungulates, red deer and wild boar Sus scrofa, as dynamic actors of contemporaneous social-ecological systems.
We thus defined three complementary components. The first one aims at defining how the diversity of usages, among which hunting, and the space dedicated to red deer and wild boar have shaped Chambord landscapes and its current habitats. The second component focuses on biodiversity and more specifically on the role of red deer and wild boar in different ecological processes. We assessed how ungulates mediate seed dispersal, how they modify the physical properties and the chemical composition of the soil and subsequently seed germination. We also considered their effects on plants’ spatial distribution and plant communities’ composition, and how these effects cascade on other taxonomic groups like birds. The last component deals with the social and economic dimension. Its aim is to value how the presence of deer influences the tourist attendance and the cultural services rendered in Chambord.
In this presentation, we will discuss the results obtained up to now, keeping in mind the global purpose of the Costaud project: to adapt the management of abundant populations of wild ungulates and of their habitats by taking into account the social-economic consequences of their impacts and the services they provide to citizens.
