    Site complementarity between biodiversity and ecosystem services in conservation planning of sparsely-populated regions.
    (Cambridge University Press, 2015-06-02) Cimon-Morin, Jérôme; Darveau, Marcel; Poulin, Monique
    The consequences of considering ecosystem services (ES) in conservation assessment are still widely debated. The degree of success depends on the extent to which biodiversity and ES can be secured under joint conservation actions. Unlike biodiversity, ES conservation is inseparably linked to human beneficiaries. Reconciling biodiversity with ES and conservation can be particularly challenging in sparsely populated areas. This study, in a sparselypopulated region of eastern Canada, focused on freshwater wetland biodiversity and ten ES provided by wetlands. Within a given maximal total area, the results showed that planning for biodiversity underrepresented local flow ES supply by 57% and demand by 61% in conservation networks. Planning for ES alone underrepresented wetland biodiversity surrogates by an average of 34%. Considering both biodiversity and ES simultaneously, all of the biodiversity and ES targets were achieved with only a 6% mean increase in area. Achieving all conservation targets starting from a network that was primarily built for either ES or biodiversity features alone was two to five times less efficient than considering both ES and biodiversity simultaneously in conservation assessment. A better framework is required to translate these spatial synergies into effective joint conservation actions.

    Towards systematic conservation planning adapted to the local flow of ecosystem services
    (Elsevier, 2014-07-30) Cimon-Morin, Jérôme; Darveau, Marcel; Poulin, Monique
    Ecosystem services (ES) are increasingly included in conservation assessment worldwide to sustain their ability to fulfill human needs. Due to the instrumental value inherent in ES, priority areas for their conservation should be selected based on their capacity to both ensure an available supply and meet beneficiary demands. However, such a methodology has yet to be developed. Aiming to adapt systematic conservation planning procedures to include ES, we conducted a case study in eastern Canada focusing on ten ES for 16 wetland types. We first delimited the ES supply accessible for human use from the total biophysical supply and mapped demand for each ES. Secondly, we assembled conservation networks targeting the accessible supply and demand and compared them with networks targeting either ES biophysical supply or accessible supply. We found that targeting only ES supply resulted in selecting sites that are not in demand and may be up to three times less efficient in fulfilling the demands of beneficiaries for local flow ES. Thus, not considering demand in ES conservation assessment fails to position reserves where ES supply is likely to be most useful. Setting conservation targets for ES supply and demand could therefore help to achieve ES conservation objectives.

    Consequences of delaying the conservation of ecosystem services in remote landscapes prone to natural resource exploitation
    (Springer, 2016-03-20) Cimon-Morin, Jérôme; Darveau, Marcel; Poulin, Monique
    Context : Natural resource extraction is expanding towards increasingly remote areas. Meanwhile, the sustainability of most ecosystem service (ES) supplies, which form a great part of the livelihoods, health and economy of inhabitants in remote regions, is threatened by large-scale land-use changes. Objective : The aim of the study was to assess the consequences of postponing ES conservation planning in remote regions prone to industrial development. More specially, is there a development threshold at which ES conservation may be imperilled. Methods : We simulated eight stages of development using actual data on hydroelectricity generation, forestry and mining expansion. Aiming to protect ten wetland’s ES provision, we assembled referential conservation networks prior to development and several alternative conservation solutions after each stage of development. We compared these networks and assessed the impact of land-use changes on the basic properties of ES conservation networks. Results : We found that conservation network alternative solutions were more costly in terms of additional area needed to achieve all targets: up to 16 % more so, compared to referential networks. Past a certain stage of development, alternative solutions were composed of a significantly greater proportion of small sites and, consequently, the networks became much more fragmented. Development also changed the spatial configuration of networks: up to 66 % of the sites included in alternative solutions were not selected in the referential networks. Conclusions : According to current trends, future development will strongly compete with ES conservation. Our study emphasizes the importance of implementing ES conservation actions before development, even in remote regions.
