 Visit 1 : 

The new Castellane district in Sathonay Camp and of an arboretum dedicated to trees adapted to climate change by Frederic Ségur. 
This new 40ha district designed as a reconversion of a former army camp which to a great extent integrates the adaptation of the city to climate change in particular by a comprehensive alternative rainwater management strategy in harmony with the landscape and an innovative strategy. As part of the Greater Lyon Canopy Plan an arboretum was recently opened to the public featuring over 100 species of trees adapted to the climate and the ground but also intended for small gardens.Led by the project managers, the visit will discuss these different approaches.



Visit 2 : 

The Champ de la Confluence, preparing the city for tomorrow's climate change, 2nd arrondissement of Lyon" is led by Marie-Paule Coassy from SPL Confluence and Jean-Marie Rogel from HORTIS – for English-speakers only! 
The “Champ” project aims to renew the image and the use of the approximately 5.5ha former ZAC Lyon industrial site as the 2nd phase of Confluence by gradually creating an urban forest, as a green and soothing refuge and protected habitat for biodiversity. 
Formed of a continuous and homogeneous landscape between private plots and public pathways, the “Champ” will create a wood bringing Nature into Town. The transition over time towards a wood leads to reflection on methods of creation and management with all the partners, private owners and public authorities alike.
To retimber the currently unfertile ground of the former wholesale market and prepare for climate change, since 2018 the SPL Lyon Confluence has been developing an experimental laboratory to explore the “field of possibilities”: the objectives of which include the ecological transition of Lyon and Greater Lyon with the creation of fertile ground, recycled concrete, adapted and local plantations and nursery gardens to grow trees on the site…
Thanks to a transitional stage, The Station Mue, the site is gradually opening to the public and makes it possible to experiment uses and propose concerted participation over the coming years.



Visit 3 :

Forests of Asia. A new space in the middle of the park de la Tête d’Or in which to get away from it all 
The Asian Forests project has meant entirely refitting an area in Lyon’s zoo including the former elephant house and the nearby enclosure to house a new biotope (flora and fauna) typical of Asian forests with careful integration of this new space to ensure it respects the landscaping and heritage spirit of the Tête d’Or park This area is home to 20 endangered species in the context of the World programme for their protection and reproduction (more than half of which feature on the IUCN Protected Species Red List), in all 80 animals. The aim is permanent animal wellbeing through the provision of habitats and space. There are 10,050 plants on the site, some of which are rare species from Lyon’s botanical gardens.
The reorganization of the building (700sq.m.) and of the external enclosure (3,000sq.m.) and the construction of two monumental aviaries made it possible to create enclosures and an indoor circuit in scenery typical of Asian forests or closely resembling them and adapted to Lyon’s weather outside the building. Through this immersion, visitors realize just how dominant these animals are in their own habitat but also of their fragility and the threats faced by these species in their natural habitats from mankind.



From the outset, Greater Lyon has been a Paysalia partner. It is important to be present because we represent the public authorities that are one of the driving forces in the landscaping sector. The organization of Paysalia also makes it possible to visit innovative projects in the Greater Lyon area and show them to other public authorities in dedicated days.
