Steve is a wetland scientist / geomorphologist with 25 years of experience in the response of coastal wetland systems to human impacts and climate change. Steve specializes in translating scientific information to formats accessible to policy and decision makers as well as senior-level managers. He also works within organizations, governments, and agencies to develop teams and initiatives that support capacity building. He regularly briefs US and Foreign governments, government agencies, and Federal, State, and local leaders. He was a lead author of the IPCC 2013 Wetland Supplement. He is an Approved Methodology Expert to the verified Carbon Standard. He leads the U.S. interagency/science community Coastal Wetland Carbon Working Group, incorporating coastal wetlands within the U.S. Inventory of GHG emissions and sinks. He also co-chairs the carbon advisory panel for the Global Environmental Facility Blue Forest Project and is the co-founder of International Blue Carbon Initiative.

Mike is a water resources engineer specializing in climate change vulnerability and risk assessments, storm flood modeling, watershed and storm water management planning, and ecological restoration planning and design. He is currently supporting the development of the San Francisco Public Utilities Commission's climate vulnerability and adaptation assessment for the multi-billion dollar sewer system improvement program, which includes cross-sector engagement with the SFPUCs Flood Resiliency Program, the Collection System Strategy Program, as well as multiple shoreline development projects that will ultimately connect to the SFPUCs combined sewer system. Mike has applied his expertise in both built and natural environments, and enjoys working with clients that need climate mitigation and adaptation solutions that span both green and gray infrastructure to reduce flood risks and provide ecological and social benefits. He stays up to date on the latest climate science, and can translate the science to develop vulnerability and risk findings that support cost-effective, multi-benefit adaptation solutions.

Lisa is a coastal ecologist with over 20 years of experience studying wetland plant ecology, carbon cycling, and soil biogeochemistry. Using field, GIS, and spatial modeling tools and techniques, Lisa examines tidal wetland and marsh resilience to sea-level rise and other climate change impacts. Through her postdoctoral work as a fellow for the Smithsonian Institution, she studied latitudinal gradients in soil carbon storage and decomposition in wetlands and mangroves from Alaska to Panama, whole ecosystem carbon dynamics in the intertidal zones of the United Arab Emirates, and methane emissions from bald cypress trunks. As a postdoctoral researcher at the San Francisco Bay National Estuarine Research Reserve, Lisa collected data on variability in suspended sediment concentrations across channels, marshes and seasons, and modeled their effects on marsh accretion under different sea-level rise scenarios.

Abby Mohan is a marine geographer and GIS analyst who works on the intersections between coastal use, coastal policy, coastal science, and best practices in communicating these cross-cutting issues to the public. Abby is active in the maritime community policy efforts and serves as the Vice Chair of the Greater Farallones National Marine Sanctuary Advisory Council (GFNMS). Abby has supported climate change vulnerability and risk assessments with a focus on sea level rise and emergent groundwater. Abby provided groundwater analysis for the Resilient by Design challenge as part of the All Bay Collective and has expanded this analysis for the city of Alameda. She is identifying areas where emergent groundwater could mobilize contaminants that exceed human-health benchmarks. She has presented this work at the National Adaptation Forum and the Bay Delta Science conference. Abby has worked with the GEF Blue Forests project translating the experiences of project managers from carbon and ecosystem service based mangrove conservation and restoration in seven countries (Abu Dhabi, Dominican Republic, Ecuador, Indonesia, Kenya, Madagascar, and Mozambique) to develop lessons learned, tools and guidance to replicate and scale up successes from these pilot projects. Prior to joining the Silvestrum team, Abby completed an internship with the Bay Conservation and Development Commission’s Adapting to Rising Tides Program and created a shoreline vulnerability index for San Francisco Bay.

Olivia is a graduate student at the University of California, Berkeley pursuing a PhD with Professor Mark Stacey in Environmental Engineering with a focus in environmental fluid mechanics. Her research is focused on the hydrodynamics of South San Francisco Bay. More specifically, she is interested in the tidal patterns of stratification and the physical mechanisms that create and destroy stratification. Olivia's time in graduate school has allowed her to gain fieldwork experience by collecting year-long salinity, velocity and temperature records in Lower South San Francisco Bay, self-teach various programming languages including Matlab, Python, and R in the context of data analysis, and use these skills to consider how this knowledge will impact future local environmental policy. She has enjoyed leading crews on deployments in San Francisco Bay to collect original data and uncover stories of what is happening in the bay from various cross-sections that she retrieved during her fieldwork.
