Both ‘natural' and managed ecosystems produce multiple ecosystem services (ES) that are connected in dynamic and complex ways, originating from a small set of ecosystem patterns and processes. The individual management of prioritized ES to optimize their provision generally results in the decrease of others. For example, as climate regulation (through C storage) has increased due to increasingly closed and dense forests, the capacity of landscapes to mitigate the size and intensity of disturbances, such as fire or insect pests, has decreased. Understanding and forecasting changes in social-ecological systems (SES), and subsequently in ES, presents significant challenges, as they are likely to display non-linear responses. Evidence indicates that they are easily ‘tipped' across critical thresholds and a narrow focus on a limited subset of ES can lead to cascading effects across multiple thresholds and sudden losses of other ES. Developing linkages between research-based knowledge and action for both sustainability and resilience requires investigating how the management of ecosystems at multiple scales for a large suite of ES could deliver ES presently desired, while preserving the ES required to meet future societal demand.

Therefore, the overarching goal of this symposium is to examine how to manage for currently prioritized ES, while retaining the option to incorporate new ES, and thereby maintain the capacity of the SES to provide values that remain hidden because they are not easily recognized or captured in market transactions. To meet this goal, we will discuss how to derive such knowledge from long-term ecological research investigations into ecosystem responses to climate and human-induced changes and concomitant changes in ES. We will explicitly identify major gaps in our understanding of generalities in the interactions between ES and trends; generalities in the interactions between thresholds among domains and scales; the conditions under which management and conservation policies backfire as multiple thresholds are breached; the role of socio-cultural thresholds in ES management; and ultimately, how to manage for currently prioritized ES, while retaining the capacity of the SES to deliver other ES in the future. Our current knowledge concerning SES dynamics, tipping points, adaptations, and epistemological bases, will be examined through three broad questions: Do we have the general theories required? How can this knowledge be used in restoration/management projects? What are the major gaps in our understanding? Specific areas to be addressed include the interactions among ES as a result of alternative management regimes; the challenges associated with leveraging ecosystem markets to actively promote cost-effective adaptation to possible futures; and relevant tools and modeling approaches. 

The session will be a speed talk-dialog (panel) session hybrid. Eight-to-ten contributors will form a panel and will be given 5 minutes to answer a set of common questions posed by the session chairs. The chairs will then open the floor to the audience and panel members to there will be a directed and structured discussion between panelists and the audience. We will follow a structured format for the discussion on managing multiple ES that includes answering questions and filling tables. The proposed outcome from this discussion a synthesis publication that identifies key research questions and information needs, as well as a brief assessment of the state of the science in this area.
