A large fraction of the current environmental crisis derives from the large rates of human-driven biodiversity loss. Biodiversity conservation questions human practices towards biodiversity and, therefore, largely conflicts with ordinary societal aspirations. Decisions on the location of protected areas, one of the most convincing conservation tools, reflect such a competitive endeavor. Operations Research (OR) brings a set of analytical models and tools capable of resolving the conflicting interests between ecology and economy. Recent technological advances have boosted the size and variety of data available to planners, thus challenging conventional approaches bounded on optimized solutions. New models and methods are needed to use such a massive amount of data in integrative schemes addressing a large variety of concerns. This study provides an overview on the past, present and future challenges that characterize spatial conservation models supported by OR. We discuss the progress of OR models and methods in spatial conservation planning and how those models may be optimized through sophisticated algorithms and computational tools. Moreover, we anticipate possible panoramas of modern spatial conservation studies supported by OR and we explore possible avenues for the design of optimized interdisciplinary collaborative platforms in the era of Big Data, through consortia where distinct players with different motivations and services meet. By enlarging the spatial, temporal, taxonomic and societal horizons of biodiversity conservation, planners navigate around multiple socioecological/environmental equilibria and are able to decide on cost-effective strategies to improve biodiversity persistence under complex environments.

Habitat fragmentation is a serious threat for the sustainability of species. Thus, the identification of effective linkages to connect valuable ecological units is an important issue in conservation biology. The design of effective linkages should take into account that areas which are adequately permeable for some species{\textquoteright} dispersal may act as obstructions for other species. The determination of minimum cost effective linkages is a generalization of both node-weighted Steiner tree and node-weighted Steiner forest problems. We compare the performance of different procedures for this problem using large real and simulated instances.

A forest cover of a graph is a spanning forest for which each component has at least two nodes. If K is a subset of nodes, a K-forest cover is a forest cover including exactly one node from K in each component. We show that the weighted two matroid intersection algorithm determines the maximum cost K-forest cover.
