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.

This paper describes the approach, planning, and field implementation of an intensive effort to eradicate a population of feral pigs from an island. Key elements of the project included comprehensive…

Guadalupe Island in Mexico is undergoing a dramatic ecological recovery following the eradication of feral goats. Unfortunately, that eradication came too late for some species and ecosystems, and…

Island archipelagos can provide useful opportunities for comparative studies in ecology. For example, breeding ecology of a songbird was studied on two of the California Channel Islands, which share…

Population models can be a critical tool in managing recovery of endangered species. This paper presents an analysis that became the foundation of recovery planning and tracking for the endangered…

Populations at very low abundance can be very difficult to detect. Consequently, one of the biggest challenges of eradication projects is determining whether an inability to detect the species at the…

To better understand the ecological role of cattle grazing in managing Carrizo Plain National Monument, we initiated a long-term study in 1997 designed to evaluate the effects of cattle grazing on…

Studies that assess the success of riparian restoration projects seldom focus on wildlife. More often, vegetation is studied, with the assumption that animal populations will recover once adequate…

With government, agency and organizational partners, Conservancy scientists helped publish an IUCN guidebook to inspire conservation investment in global marine protection and provide a case study…

One of the greatest challenges in pest eradication is knowing when it has been achieved. This paper discusses why that is challenging, and why it is so important to consider how that challenge will be…

Restoration efforts on the Sacramento River are focusing on revegetating the land with native plants and restoring natural river processes in an attempt to recover wildlife populations. To evaluate…

River restoration projects have the potential to influence many of the services that rivers provide to people, yet rarely is this studied in a comprehensive manner. This paper reports on a set of…

For the International Year of Deserts and Desertification, 2006, a team of environmental and social scientists assembled to assess the state of the world’s deserts. This report is the product of…

Livestock grazing in the American West often conjures up images of cattle degrading riparian areas or spreading weeds throughout desert rangeland. But cattle grazing does not always or necessarily…

Fragmentation-sensitive species – those that tend to disappear when their habitat is fragmented – pose particular challenges for conservation, in part because fragmentation ushers in such…

Reproductive success of many species in arid environments can be sensitive to rainfall patterns: rainfall events can produce a boom of primary productivity that fuels an ecological response from the…

Habitat fragmentation ushers in a wide array of ecological changes, and understanding the drivers and impacts of those changes is critical for conservation management. This study examines an often…
