Urban development frequently creates vacant lots, unused properties with no built structures in which original vegetation was at least partially cleared. As such, vacant lots have the potential to serve communities by providing ecosystem services, but they can also be managed or restored to provide either original or newly needed ecosystem services. In that sense, considering the protection and restoration of vacant lots may improve the efficiency in urban conservation planning. In this study, we aim to evaluate the cost-benefits of including vacant lots in systematic conservation planning focusing in the conservation of ecosystem services, as well as the restoration of bundles of demanded ecosystem services in vacant lots. We will use Marxan with Zones to identify conservation and restoration priorities based on the flow of six ecosystem services provided by urban forests and vacant lots in the agglomeration of Quebec (temperature regulation, carbon storage, water flow regulation, vegetable gardens pollination, recreation and aesthetical appreciation). During the site selection for conservation planning, costs will consider the land size, local price, ecosystem conditions, and restoration objectives. We will test scenarios with and without considering the conservation or restoration of vacant lots, in addition to urban forests. We will also compare scenarios of management based on the demand of specific bundles of ecosystem services. Stakeholders will be consulted to avoid selecting lots with higher development probability. We expect to create a guideline for vacant lots management in urban environments aiming to maximize the delivery of ecosystem services and biodiversity in urban contexts.
