Abstract: Abstract 1: Design persistent protected areas to form representative conservation networks: solving the dual problem to protect ecosystem functions and biodiversity on the long term —Case study: conservation planning in Quebec’s Moyen Nord Recent developments in conservation planning integrate persistence of biodiversity on the long term with representation objective. To maintain biodiversity on the long-term and keep its dynamic aspect, criteria of size, intactness and connectivity are identified as key components in the design process. Our systematic conservation planning method considers all three features through protected areas known as ecological benchmarks that 1) are big enough to sustain large-scale ecological process such as fire, 2) are highly intact to be used as reference sites and 3) are connected via the hydrological system using catchments as planning units in order to protect freshwaters. Promoting persistence, ecological benchmarks can be assembled to form networks that are in aggregate representative. We developed two automated algorithms to build benchmarks (Builder) and to combine them into potential networks that are ranked from most performing to worst according to their representation (Ranker). The method was tested for the first time in the province of Quebec. Abstract 2: Developing conciliation between mining and protected areas using a decision making system to plan for representative conservation networks Recognizing the economic importance of the mining industry and the ecological importance of safeguarding biodiversity, there is a need to develop better conciliation of these two elements during land-use planning. In this study, we present a decision-making system which allows the comparison of different conservation scenarios according to their capacity to represent biodiversity. The method has been applied in Quebec’s Moyen Nord to analyze scenarios enlarging the existing conservation network until 12 and 17 % of the territory is reached using persistent protected areas known as ecological benchmarks. These scenarios excluded mining activity zones to verify if it is possible to establish a representative protected areas network which maximizes the protection of biodiversity while minimizing the impacts on the mining industry.
