PASSAGES FAUNIQUES RAPHAEL JUSTEWICZ, ASLA, AIA, LEED AP WILDLIFE ON THE MOVE: SEEING RED 6 FR_ VOIR ROUGE Janet Rosenberg + Associates a été choisie comme l’un des cinq finalistes du concours international de passages fauniques de l’ARC (Denver, Colorado). Comme finaliste, l’équipe a entrepris la tâche complexe de réinventer les passages fauniques classiques. Au lieu d’attendre que les animaux s’adaptent aux structures, l’équipe a voulu adapter l’environnement construit aux besoins de la faune. Le concept a été façonné par l’analyse des indices du paysage vivant, de la manière dont la faune s’y déplace et de ses réactions à la lumière, à la couleur, à l’odeur, au goût et au son. L’équipe a senti que ce concours pouvait marquer un tournant pour la profession : la structure de passage faunique faisait son entrée dans l’univers de l’architecte paysagiste. Le nouveau défi nécessitait entre autres une étude approfondie des sciences de l’écologie et de la restauration, des entretiens avec l’expert en comportement animal Temple Grandin et une recherche de matériaux nouveaux.

To our delight, our team was one of five finalists assigned the complex task of re-conceptualizing the conventional animal road crossing. We set out to produce not simply a bridge, but a new species in form and function. Instead of expecting wildlife to adapt to the structures we design for them, we wanted to adapt the built environment to the needs of wildlife. Our design would be shaped by analyzing the clues in the living landscape, how wildlife moved through it, and their reactions to light, colour, smell, taste and sound. We sensed that this competition could become a defining moment for the profession: the wildlife crossing structure was being adopted into the landscape architect’s realm. We had taken on the challenge in part at the urging of Nina-Marie Lister, a Toronto academic who was a driving force behind the competition, recruiting many prominent firms to enter. E COLOGICAL URBANISM AT WORK The competition was triggered by escalating costs of standard crossings: a five-fold increase over the past ten years. As well, the current bridge model was conceptually out of date. Road ecology has developed into a highly investigative science. Our team included Kari Gunson, a road ecologist at the forefront of this work. REALITY ON THE ROAD The five teams of finalists travelled the busy I-70 highway in West Vail, to a particular spot where animal and vehicle collisions are very common. Close to 19,000 vehicles travel this stretch per day (2008). Beyond it, in the forest bordering the highway, are 280,000 SPRING PRINTEMPS <strong>2011</strong> 27
