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.

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…

Critical for biodiversity conservation is the retention of ecological connectivity in the landscape, so that wildlife—and the natural processes that sustain wildlife—can move around.…

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…

The California South Coast Ecoregion, a global biodiversity hotspot, is bisected by the US-Mexico border. Development near the border, ranging from urban sprawl to border security infrastructure,…

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…

This study is the first marine gap analysis for California. It quantifies what is protected and what is not and highlights conservation needs and opportunities. Less than 5% of marine habitats are…

The Conservancy's science and planning staff in California prepared this assessment of the most important areas for conservation of marine biodiversity in the Northern California…

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…

The Conservancy's science and planning staff in California prepared this assessment of the most important areas for conservation of marine biodiversity in the Southern California Marine…

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…
