We identify issues and uncertainties that pose obstacles to conservation and then—in collaboration with internal and external colleagues—develop science products that help overcome those obstacles.

Seagrasses, oyster reefs, and salt marshes are critical coastal habitats that support high densities of juvenile fish and invertebrates. Yet which species are enhanced through these nursery habitats, and to what degree, remains largely unquantified. Quantitative estimates of production enhancement within specific embayments can be…

Every year, infrastructure agencies and developers spend hundreds of millions of dollars to mitigate for impacts to sensitive species and habitats. These mitigation sites are often piecemeal projects, which can result in islands of mitigation. Regional advance mitigation programs seek to change this paradigm so…

Kelp forests around the world are experiencing significant declines due to a variety of factors, driving the need for more active kelp restoration efforts. The science and practice of kelp forest restoration is still in its infancy and there remains a wealth of knowledge to…

With increase in devasting storms and wildfires due to climate change, we need solutions to help mitigate the impact. Traditionally, “gray” or “hard” infrastructure solutions that rely on engineering projects using concrete and steel have dominated efforts to manage risk and mitigate hazard impacts…

The great whales, including, blue, humpback, and fin whales are threatened by collisions with ocean going vessels. Global shipping traffic is projected to increase up to 12-fold in coming decades. Slowing vessels down reduces the risk of whale collisions and mortality. Here, the authors examined…

More than 4.5 million fishing vessels ply ocean waters each year, setting countless nets, traps, hooks and lines. Much of this fishing gear is made of plastic components and a significant fraction of it is lost in the ocean each year, causing irreparable harm to…

Overfishing threatens the health of ocean ecosystems. Effective fisheries management is key to minimizing ocean impacts and improving outcomes for millions of fishing dependent people throughout the world. Most fisheries, however, lack sufficient data for managers to perform quantitative stock assessments and inform management regulations.…

Native forests on tropical islands have been displaced by non-native species, leading to calls for their transformation. Simultaneously, there is increasing recognition that tropical forests can help sequester carbon that would otherwise enter the atmosphere. At Palmyra Atoll, efforts are underway to transform the rainforest…

The Nature Conservancy deploys science to help overcome major challenges facing people and nature. In today’s fast-paced world, turning threats to nature into opportunities for conservation requires agility. The Conservation Science Catalyst Fund enables our science team to mobilize quickly — and produce the information…

This 5-year action plan describes the vision for invasive plant species mapping, monitoring and treatment at the Jack and Laura Dangermond Preserve in Sourthern California. The plan is adaptive and will updated as new species, management approaches (including new and emerging technologies), and monitoring results…

The United States operates thousands of military installations in the U.S. and worldwide, worth about $1.2 trillion. These facilities are where personnel train and test weaponry, with the specific aim of ensuring the nation’s security. With climate change, coastal installations are now being impacted by rising sea levels, erosion and…

The U.S. Congress and the Department of Defense (DoD) have determined that climate change is a threat to national security and have required military installations to develop plans to improve the climate resilience of both military installations and key supporting civilian infrastructure. This report, co-authored…

Global kelp forests are biodiverse and productive nearshore ecosystems that provide a wide range of ecosystem services, but they are at risk from both local stressors and global drivers of kelp loss. A structured decision making (SDM) framework can help guide kelp management and restoration…

The health of ocean ecosystems is critical to maintaining natural biodiversity and sustainable fisheries, but federally-declared fishery disasters are reflecting devastating impacts to ecosystems, economies, and communities. This study represents the first nationwide synthesis of fishery disasters during the 30-year history of the federal assistance…
