Adina Merenlender (born October 1, 1963) is a Professor of Cooperative Extension in Conservation Science at University of California, Berkeley in the Environmental Science, Policy, and Management Department, and is an internationally recognized conservation biologist known for land-use planning, watershed science, landscape connectivity, and naturalist and stewardship training.
Merenlender was born in Seattle, Washington and raised in West Los Angeles, California. [2]
Merenlender graduated from UC California San Diego in 1985 with a BA in Biology, where she also received her MS from the Department of Ecology and Evolutionary Biology in 1986. [3] She was a visiting graduate student at Princeton University from 1987 to 1993, [4] and she graduated from the University of Rochester in 1993 with a PhD in Biology. [3]
After earning her PhD in Biology, Merenlender did her post-doctoral fellowship at the Center for Conservation Biology at Stanford University from 1993-1995, [5] researching riparian plant and aquatic insect communities on Great Basin working lands under different livestock grazing regimes. [6] She started her career at UC Berkeley as assistant cooperative extension specialist and adjunct professor in 1995, at which time she moved to Mendocino County to conduct research at the UC Hopland Research and Extension Center, a 5,000-acre field station. [5]
Upon arriving in California's wine country, Merenlender conducted some of the first research in Vinecology, [7] the integration of ecological and viticultural practice to produce solutions for wine production and nature conservation. [8] Merenlender continues to advance conservation. [9] [10] [11] Her work across California's North Coast vineyard landscape also includes watershed studies, revealing ways to avoid summer water withdrawals from streams to irrigate wine grapes, which is a necessary step to recovering California's salmon runs. [12] [13]
Merenlender led the earliest inquiries into the realized conservation benefits, or lack thereof, from conservation easements which spurred a large and still-growing body of scholarship on the topic. [14] She also provided some of the first evidence for the impacts of quiet recreation on meso-carnivores and sparked continued field research into recreation management to minimize these impacts. [15] [16]
Merenlender started the California Naturalist Program [17] and served as its founding director, [5] [18] which to date has graduated over 4,000 certified California Naturalists. Building on the success of this program, Merenlender helped start the first public education and service program on climate stewardship, [19] including writing Climate Stewardship: Taking Collective Action to Protect California with Brendan Buhler. [20] [21] The two programs provide collective impact on ecological health through community and citizen science.
In 2004, Merenlender was a visiting scholar at the University of Queensland Department of Zoology in Brisbane, Australia. She was also a visiting scholar at the National Autonomous University of Mexico (UNAM) in Mexico City in 2008, and with the Cambridge Conservation Initiative through the University of Cambridge Zoology Department in 2019. [5]
As president, Merenlender worked with the Governing Board and staff to reorganize the Society of Conservation Biology as a global network to preserve biodiversity.
Merenlender has published over 100 scientific research articles on the relationships between land use and biodiversity, [5] and co-authored a book on wildlife corridor planning, Corridor Ecology: The science and practice of linking landscapes for biodiversity conservation, [28] with the first edition published in 2006 and the second in 2019. She also co-authored The California Naturalist Handbook, [29] and Climate Stewardship: Taking Collective Action to Protect California. [21]
Conservation biology is the study of the conservation of nature and of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions. It is an interdisciplinary subject drawing on natural and social sciences, and the practice of natural resource management.
Habitat conservation is a management practice that seeks to conserve, protect and restore habitats and prevent species extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology.
An ecological or environmental crisis occurs when changes to the environment of a species or population destabilizes its continued survival. Some of the important causes include:
A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. Norman Myers wrote about the concept in two articles in The Environmentalist in 1988 and 1990, after which the concept was revised following thorough analysis by Myers and others into “Hotspots: Earth’s Biologically Richest and Most Endangered Terrestrial Ecoregions” and a paper published in the journal Nature, both in 2000.
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment, and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats.
In conservation biology, a flagship species is a species chosen to raise support for biodiversity conservation in a given place or social context. Definitions have varied, but they have tended to focus on the strategic goals and the socio-economic nature of the concept, to support the marketing of a conservation effort. The species need to be popular, to work as symbols or icons, and to stimulate people to provide money or support.
The Lower Guinean forests also known as the Lower Guinean-Congolian forests, are a region of coastal tropical moist broadleaf forest in West Africa, extending along the eastern coast of the Gulf of Guinea from eastern Benin through Nigeria and Cameroon.
A conservation-dependent species is a species which has been categorized as "Conservation Dependent" ("LR/cd") by the International Union for Conservation of Nature (IUCN), as dependent on conservation efforts to prevent it from becoming endangered. A species that is reliant on the conservation attempts of humans is considered conservation dependent. Such species must be the focus of a continuing species-specific and/or habitat-specific conservation program, the cessation of which would result in the species qualifying for one of the threatened categories within a period of five years. The determination of status is constantly monitored and can change.
In landscape ecology, landscape connectivity is, broadly, "the degree to which the landscape facilitates or impedes movement among resource patches". Alternatively, connectivity may be a continuous property of the landscape and independent of patches and paths. Connectivity includes both structural connectivity and functional connectivity. Functional connectivity includes actual connectivity and potential connectivity in which movement paths are estimated using the life-history data.
MARXAN is a family of software designed to aid systematic reserve design on conservation planning. With the use of stochastic optimisation routines Marxan generates spatial reserve systems that achieve particular biodiversity representation goals with reasonable optimality. Over the years, Marxan has grown from its standard two zone application to consider more complex challenges like incorporating connectivity, probabilities and multiple zones. Along the way, Marxan’s user community has also built plug-ins and interfaces to assist with planning projects.
A wildlife corridor, habitat corridor, or green corridor is an area of habitat connecting wildlife populations separated by human activities or structures. This allows an exchange of individuals between populations, which may help prevent the negative effects of inbreeding and reduced genetic diversity that often occur within isolated populations. Corridors may also help facilitate the re-establishment of populations that have been reduced or eliminated due to random events. This may moderate some of the worst effects of habitat fragmentation, whereas urbanization can split up habitat areas, causing animals to lose both their natural habitat and the ability to move between regions to access resources. Habitat fragmentation due to human development is an ever-increasing threat to biodiversity, and habitat corridors serve to manage its effects.
Global biodiversity is the measure of biodiversity on planet Earth and is defined as the total variability of life forms. More than 99 percent of all species that ever lived on Earth are estimated to be extinct. Estimates on the number of Earth's current species range from 2 million to 1 trillion, but most estimates are around 11 million species or fewer. About 1.74 million species were databased as of 2018, and over 80 percent have not yet been described. The total amount of DNA base pairs on Earth, as a possible approximation of global biodiversity, is estimated at 5.0 x 1037, and weighs 50 billion tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).

Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent. The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far. These activities include habitat destruction and land use intensification. Further problem areas are air and water pollution, over-exploitation, invasive species and climate change.
Erika S. Zavaleta is an American professor of ecology and evolutionary biology at the University of California, Santa Cruz. Zavaleta is recognized for her research focusing on topics including plant community ecology, conservation practices for terrestrial ecosystems, and impacts of community dynamics on ecosystem functions.
The Landscape Conservation Cooperatives (LCC), established in 2009 in the United States, are a network of 22 regional conservation bodies covering the entire United States and adjacent areas. They are autonomous cooperatives sponsored by the U.S. Department of the Interior and aim to develop coordinated conservation strategies applicable to large areas of land. Partnerships are formed with government and non-government conservation organizations to achieve common goals of conservation. While fairly new as government supported entities, the LCCs are similar to initiatives that have been started or advocated in other countries.

Working landscapes are landscapes used for farming, ranching and/or forestry. Recently, these have become the focus of efforts to conserve biodiversity, as these now cover more than 80% of Earth's land, and therefore offer increasing opportunities for conservation and restoration. Though some parts of these landscapes may be used so intensively that they may be unable to sustain native species, working landscapes generally also include significant areas of habitats suitable for native species within their diverse and multifunctional mosaics of intensively used, fallow, and regenerating areas.
