CAVENDISH-LAURIN-LIESSE BIODIVERSITY CORRIDOR
Most Western cities are founded on principles of stability and permanence. Change or uncertainty, often present in the form of rich, complex landscape systems, has generally been erased, leveled, denuded or marginalized. Our proposal adopts an approach in which change is the baseline. Stability, certainty and order give way to a design oriented towards adaptability, resilience and flexibility.
The Biodiversity Corridor is conceived as a social, green and blue infrastructure. This involves the creation of a network of ecological and urban elements with the same objectives: the preservation of ecosystems, the creation of new natural environments, the enhancement of biodiversity, water management and the planning of recreational and cultural spaces. In order to achieve these objectives, the master plan has been developed according to the following strategies:
Protection of existing habitats: analysis of the current situation and identification of the main green spaces show the presence of wildlife and plant habitats to be protected. These habitats will be consolidated and enhanced by creating buffer zones and reducing human disturbance.
Creating new habitats: in addition to preserving existing environments, new habitats will be created through urban reforestation interventions - where possible - and by diversifying the abiotic and biotic elements of available green spaces. In this sense, the proposal seeks to concentrate the composition and arrangement of plant species (e.g. the creation of meadows), but also the diversification of soil and microclimate matrices. The creation of new habitats will generate a heterogeneous ecosystem, capable of supporting multiple plant and animal species.
The relationship between habitats: to avoid fragmentation of habitats, it will be important to maximize their connectivity. This will be done by creating tree-lined rows, reclaiming marginal areas, eliminating physical barriers, converting mineral surfaces to vegetation and integrating wildlife crossings in sensitive areas.
Multifunctionality: Finally, the recreational offer will be enhanced through the creation of hiking and cycling trails, rest areas, sports practice zones and event areas. In addition, to raise awareness and educate the public, signage will be put in place to highlight the importance of the Corridor's ecological aspects and showcase its various habitats.
These actions are implemented through the design of a diversified landscape comprising both public interventions and guidelines for private areas.
The scope of intervention will be implemented at two levels: seasonal variability and the dynamics of ecosystem evolution. Seasonal variability aims to diversify the use of areas throughout the year. Short-term interventions (operational scope, 2021-2023) will develop the ecosystem's foundations so that it can then, in the long term, follow a desired evolutionary trajectory towards an optimal stage. On the other hand, long-term planning takes into account the dynamics and evolution of the ecosystem. A long-term vision of interventions and a prediction of succession dynamics can ensure the constitution of a more resilient urban environment.

The jury praised the proposal's understanding of the mandate and the territory, notably through the creation of a map summarizing the issues raised in the program and its appendices. The proposal is simple, systematic and organized, and demonstrates a clear project approach that fits in well with the development of a master plan and a biodiversity corridor (pathways, meshing). The diagrams clearly express the strategy, vision and main principles that interact with each other. The porosity of the master plan and the delicacy of the elements suggest the potential to evolve in this direction. The jury also appreciates the consideration given to the private domain and winter, as well as the relationship with other issues in the area, such as existing and planned transport infrastructures (local travel plan). The proposal thus provides an excellent basis for future work.
The jury members noted, however, that the proposal remains Cartesian. A stronger spatial concept needs to be developed and represented; a stronger identity needs to be defined and federated. The jury is also keen to gain a better understanding of the social infrastructure that the team has outlined. The notion of connectivity also needs to be anchored in concrete uses of the territory. What human, social and cultural experiences are proposed? What ambiences, what scenarios of appropriation are envisaged? Finally, the jury expressed misgivings about the proposed shelter/promontory (scale ratio), noting that such a structure does not seem suited to the density of population and the location in which it is set.
