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 study examined spotted owl habitat selection after the King Fire in California using satellite tracking of 26 different owls . The authors found that whether severe fire was "good" or "bad" for owls depended on patch size and configuration: owls selected smaller but avoided…

Agriculture-dominated landscapes harbor significantly diminished biodiversity. Woody vegetation along field margins can provide farmers with ecosystem services and benefit biodiversity. However, when crops are damaged by the biodiversity harbored in such vegetation, farmers are reluctant to incorporate field margin habitat onto their land and may…

In response to anomalously warm sea-surface temperatures, poleward shifts in the geographic range of hundreds of marine organisms worldwide have been documented. This paper reports on the unusual occurrences of 36 fish species recorded from the Southern California Current System (SCCS) during the period of…

This paper evaluates how endangered species with highly restricted habitat needs and increasingly small population sizes (using blunt-nosed leopard lizard as our example), select and use available habitat. The paper paired a novel experimental – telemetry and remotely-sensed data – and analytical – resource selection…

Chinook, coho and steelhead were once tremendously abundant in most of California’s major rivers and streams. As recently as the 1960s, salmon and steelhead were so plentiful in streams that horses would get spooked trying to cross. Due to water damming and diversions, habitat degradation and…

Conservation needs to harness technology to meet the complex challenges of today’s world. The Technology Catalyst Fund provides early stage resources to investigate and prototype technologies that have high potential for impact and have effectively disrupted the status quo in other sectors. The Fund empowers…
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…

The authors of this paper are engaged in developing flow criteria for California Streams through California Environmental Flows Framework (CEFF) collaboration. The effort is funded by the State Water Resources Control Board. This collaboration is a working group within the California Water Quality Monitoring Council. This…

In this article, the authors provide an example of how dynamic multi-benefit solutions used to provide “pop-up” wetland habitat for migratory birds also replenishing depleted aquifers to create environmental and water supply benefits and broadens it to the global scale. Additionally, this article outlines six…
The Oren Pollak Memorial Research Fund was established in 2000 in memory of Dr. Oren Pollak, a leading grassland ecologist and restoration pioneer, as well as an ardent champion and mentor for grassland ecology students. As The Nature Conservancy’s lead ecologist in California in the…

Using a newly developed tool for estimating streamflow depletion from groundwater pumping, this study examined the impacts of ongoing groundwater pumping on streamflow and aquatic ecosystems in the Navarro watershed in rural, coastal California. The study found that common uses of groundwater in the watershed,…

In an effort to address climate change, California enacted a clean energy energy standard that is driving a market for significant amounts of renewable energy. To explore the economic benefits of developing utility-scale solar energy on low biodiversity value land, the authors conducted an analysis…

Management of protected lands may enhance ecosystem services that conservation programs were designed to protect. Practices that build soil organic matter on agricultural lands also increase soil water holding capacity, potentially reducing climatic water deficit, increasing actual evapotranspiration and increasing groundwater recharge. The authors of this…

Groundwater plays an essential role in supporting freshwater species, riparian habitats, and migratory birds. These ecological communities, commonly referred to as groundwater-dependent ecosystems (GDEs), can suffer undesirable impacts from unsustainable pumping practices. This study assessed whether ecosystem health varied with groundwater availability in riparian forests in California’s…

In Western North America, droughts are expected to increase in frequency and intensity as the region’s climate changes. Over past decades, land managers on Santa Cruz Island, California witnessed mass mortality of conifer forest dominated by bishop pine (Pinus muricata). These pines play a key role within…

This paper furthers our understanding of what makes some species rare, and others more common. The authors grew monocultures of 18 California grassland plant species and measured their growth and ability to alter soil properties such as moisture and nutrients. Then they related these metrics…

Agricultural management practices impacts not only on crops and livestock, but also soil health, water quality, wildlife, and ecosystem services. There is abundant, but disconnected, scientific evidence for the impacts of different practice. But this evidence is often not used in decision making by farmers or…

Although environmental conservation, human health, and sustainable development challenges are interconnected, approaches to these challenges and the evidence used remain disconnected. Creating integrated solutions across these sectors will require better alignment of the methods used to assess the problems and quantifying success. In this review,…
