Miranda Gray awarded a Wilburforce Fellowship in Conservation Science

Miranda Gray awarded a Wilburforce Fellowship in Conservation Science

CSP is proud to announce that Miranda Gray, Lead Scientist, is one of 20 new Wilburforce Fellows for 2017.

The Wilburforce Fellowship in Conservation Science is a year-long program that gives participants tools to bridge the gap between science and policy, providing training in leadership and science communication. Now in its second year, the Fellowship encourages scientists to not only advance decision-relevant research but also to contribute to conservation solutions by engaging with local communities, policymakers, land managers, and those with diverse perspectives to help sustain wildlife and wildlands. Fellows are selected via a competitive process on the basis of their skills, experience, and passion for conservation in the West.

Miranda applies quantitative methods to ecological problems. One of her areas of expertise is modeling landscape connectivity for ecological processes, a skill she has used to pioneer new works in the realm of fire ecology. Miranda is hoping to build a broader constellation of relationships and develop conservation solutions through collaborative processes. She will join her cohorts in Tucson for a 6-day intensive training this April. During this training, the fellows will set goals for engagement on a conservation issue, start defining an action plan to achieve these goals, and learn a variety of communication and leadership skills, including storytelling, framing, and messaging.

New CSP study examines the impacts of OHV roads on the space use patterns of the kit fox

New CSP study examines the impacts of OHV roads on the space use patterns of the kit fox

An analysis by CSP finds a strong correlation between the density of off-highway vehicle (OHV) road networks and space use by Sonoran Desert kit fox during the winter months.

The kit fox, a species that inhabits low-elevation regions of Arizona’s Sonoran Desert, was the subject of a collaboration between CSP and researchers from Arizona Game & Fish Department. Kit fox populations in this area have been declining in response to industrial, agricultural, and urban development. This study, published in The Journal of Wildlife Management, is the first to specifically investigate the relationship between OHV road networks and kit fox space use.

CSP’s Jesse Anderson and Brett Dickson used several types of information for this study — monitoring data collected for 22 foxes over a 3-year period, spatial (landscape) data, and aerial surveys of OHV use — to assess environmental variables such as road density, topographic features, and distance to water and development. The study area included two sites in central Arizona.

They found that only one variable — road density in winter — correlated strongly to negative space use impacts (that is, a decrease in the amount and/or quality of available kit fox habitat). This result is likely due to higher OHV use during the cooler winter months, when kit foxes engage in breeding, denning, and pupping activities.

The study results suggest that expanding OHV road networks will likely result in habitat loss for kit foxes. Managers will ultimately need to balance these types of recreational opportunities with the need to conserve habitat for species such as the kit fox.

An ecological case for designating the Greater Grand Canyon Heritage National Monument

An ecological case for designating the Greater Grand Canyon Heritage National Monument

Recent work by CSP finds that the proposed Greater Grand Canyon Heritage National Monument (GGCNHM) — one of the last truly wild areas in the West — presents a unique opportunity for protecting ecological functions.

CSP has been engaged in various landscape-level analyses to identify areas of high ecological value in undeveloped lands throughout the western U.S. A recent connectivity study conducted by Brett Dickson and others[1] identified three notable areas in the West with high ecological flow. One of these areas is the proposed GGCNHM in northern Arizona. If designated, the monument would permanently protect 1.78 million acres of land surrounding Grand Canyon National Park that are currently threatened by increased development, logging, and a resurgence of uranium mining.

Earlier this year, CSP and the Center for American Progress (CAP) initiated a study to further assess the proposed GGCNHM’s ecological importance. CSP had previously collaborated with CAP on the groundbreaking Disappearing West project, which found that we are losing natural areas to human development at an alarmingly fast rate. CSP’s role in GGCNHM study entailed conducting a West-wide comparative analysis of various key indicators that included resilience to climate change, ecological connectivity and intactness, biodiversity, and remoteness. The analysis demonstrated that this area far exceeds other similar-size western landscapes in terms of ecological connectivity and intactness, geophysical uniqueness, and richness of rare and irreplaceable species. According to CAP, the study “makes an irrefutable scientific case for protecting this area.”

The proposed designation clearly presents a unique opportunity to conserve key elements of ecological function within the region. What may be less obvious is the opportunity this presents for the entire western U.S.; designating this monument would strategically strengthen our existing network of protected areas in the face of climate change. The GGCHNM’s value in sustaining large, contiguous landscapes that support high levels of regional biodiversity should not be underestimated.

CSP identifies vulnerable Sierra Nevada meadows using climate and remote sensing data

CSP study identifies vulnerable Sierra Nevada meadows using historical climate and remote sensing data

CSP is developing a decision framework for focusing restoration and conservation actions in Sierra Nevada meadows based on an assessment of their vulnerability to climate change.

Two CSP scientists — Christine Albano and Meredith McClure — are leading a study of meadow ecosystems in the Sierra Nevada ecoregion. The 2-year study, which kicked off this past July, involves developing a tool to identify the most vulnerable meadows to guide decision-making and monitoring in these areas. The CSP team is working with scientists from the Desert Research Institute (DRI) as well as resource managers from the Forest Service. The resulting decision-support tool will be piloted by the Amador-Calaveras Consensus Group (ACCG), a consortium of 34 organizations that plans to prioritize 20 meadows for restoration in the upper Mokelumne, Stanislaus, Calaveras, and Consumnes watersheds of California.

The study focuses on meadows because of their ecological significance. Although they comprise less than 1 percent of lands within the Sierra Nevada ecoregion, meadows perform critical functions: they store carbon and nitrogen, mediate surface water flows, recharge aquifers, filter sediments, and provide refugia for numerous species. Unfortunately, they are highly vulnerable to climate variations because they depend largely on shallow groundwater systems to feed surface flows, seeps, and springs. These systems can be profoundly affected by rising temperatures and reductions in rainfall and snow pack.

To assess how vegetation has changed in response to variations in climate, the research team is analyzing 26 years of data for about 6,000 meadows and evaluating these responses in the context of geologic, topographic, and hydrologic factors. The project builds on existing work —datasets, analyses, computational methods, and software — developed by the PIs and partners. Stakeholders will be able to visualize vegetation conditions under various climate scenarios and time scales using a Google Earth technology.

CSP develops a strategic, practical solution to conserving biodiversity and habitat connectivity

A strategic, practical solution to conserving biodiversity and habitat connectivity in our Disappearing West

CSP uses concepts from electronic circuit theory to identify and map critical tracts of land that can serve as “connective tissue” between existing protected areas.

The results of CSP’s Disappearing West analysis, published online earlier this year, identified where — and how fast — we are losing natural areas to human development. This work, which garnered international attention, posed a call to action for new conservation measures to prevent the further loss of biodiversity and ecological functions across the West, particularly in the face of rapid land cover and climate changes.

Now a new CSP study provides a tool for doing just this — in the most efficient way possible. Rather than targeting large areas for conservation efforts, which can be politically challenging, the study identifies relatively small tracts of land that would best connect habitat between existing protected areas (PAs). This “less is more” approach offers a more practical, optimized, and less costly solution for identifying and conserving public lands that are currently unprotected.

An innovative, quantitative approach

The study used high-resolution data from the Disappearing West project, which identified the level of human modification caused by multiple stressors such as urbanization, energy development, and transportation corridors. It also builds on a previous CSP investigation of unprotected, roadless Bureau of Land Management (BLM) lands in the West.

For this new analysis, CSP combined its model of human modification with a circuit-theory-based model of habitat connectivity to simulate patterns of “ecological flow” between existing PAs and across broad landscapes. Circuit models assume that ecological processes (such as individual movement and gene flow) are analogous to the flow of electrical current through a network of resistors. They calculate the potential current flow and voltage across a grid that represents a heterogeneous landscape characterized by differing resistance levels, depending on the amount of human modification. Although circuit theory has been used in ecology for about a decade, researchers typically model PAs as large, homogeneous patches with zero resistance to represent the condition of no human development. CSP, on the other hand, considered human modification, both within PAs and elsewhere, while also incorporating the likely effects of natural barriers such as steep slopes and rivers on the potential movement of plants and wildlife. The results of this analysis are not only far more realistic but they also facilitate in-depth comparison across management jurisdictions.

Another unique feature of this study is its large geographic scope; the connectivity model covers eleven western states in the U.S: Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming. In addition, the study results, provided as a series of highly detailed, open-source maps and data sets, are completely “species neutral” and can therefore be applied to future studies of all plants and wildlife.

Results and significance

In addition to revealing key connective lands between PAs, CSP’s model indicates three notable areas with high ecological flow: southern Oregon / Idaho, northern Arizona / central Utah, and much of Nevada, where the orientation of Basin and Range landforms appears to encourage flow between northwestern and southwestern states. Many of these areas lay within the BLM’s jurisdiction.

According to Brett Dickson, CSP’s President and Chief Scientist, the results of this study underscore the ecological value of BLM lands, which are often “underappreciated” by conservationists. These results may also have profound implications for nominating Areas of Critical Environmental Concern (ACECs) — special management areas designated by the BLM to protect, among other things, significant ecological resources. Determined through an administrative (rather than legislative or executive) process, ACECs may be nominated by any entity. CSP’s study provides critical information on connectivity that can support ACEC nominations, filling a key data gap for those involved in conservation efforts in the western U.S. The study results can also inform legislative or executive actions to expand Wilderness Areas, Wilderness Study Areas, National Monuments, National Conservation Areas, and other lands in the National Conservation Lands system.

CSP publishes a survey design for monitoring global environmental change

CSP publishes a survey design for monitoring global environmental change

CSP’s Dave Theobald published a paper in the September 2016 issue of Remote Sensing describing a project that has significant implications for collaborative and citizen science.

The paper recaps Theobald’s work designing a general-purpose spatial survey for monitoring environmental changes on a global scale. The primary product of this project is a massive database — the “Global Grid”— that maps all locations across the globe (at resolutions down to about 1 square kilometer) with a randomized sequence number. CSP is currently using the Grid for several projects, including one that entails generating a global dataset for land use and land cover validation.

The Global Grid has several unique features. Its design is not only probability based, but it is also flexible, multi-scale, and globally comprehensive. The Grid builds on previous work of the U.S. EPA and others. Its design is intended to both optimize and standardize sampling locations for environmental monitoring, for a variety of resource types, for application across institutional and administrative boundaries. It is available in a variety of open-source formats.

Bat study kicks off to fight deadly disease as it spreads west

Bat study kicks off to fight deadly disease as it spreads west

The Wildlife Conservation Society (WCS) recently launched a 4-year study to help scientists understand the occurrence of White Nose Syndrome (WNS) in Western bats.

408px-little_brown_bat_with_white_nose_syndrome_greeley_mine_croppedCSP’s Brett Dickson, a co-PI for this study, will work with a group of scientists from WCS, WCS Canada, Texas Tech University, Montana State University, and Massey University. Funded by the Strategic Environmental Research and Development Program, the study will look at WNS occurrence within and around military installations.

CSP will be responsible for developing several models to help forecast the likelihood of exposure and mortality for unaffected populations of target species. The resulting maps of current and future bat habitat will help managers identify how susceptible species might shift their distribution under a changing climate.

WNS, which emerged in 2006 and has already caused widespread mortality and threatened some Eastern bat species with extinction, had been advancing westward at an alarming rate. In March 2016, however, a WNS-infected bat was discovered in Washington State — the first recorded occurrence of the disease in western North America. Caused by a fungal pathogen and named for the white fungus on the muzzles and wings of affected bats, the disease alters the physiology and bioenergetics of hibernation, leading to increased arousal and depletion of fat stores.

A new look at Disappearing West data reveals a need for environmental justice

A new look at Disappearing West data reveals a need for environmental justice

A study by the Center for American Progress (CAP) and CSP finds that minority and low-income communities have disproportionately less open space and natural areas nearby as compared to statewide averages.

CSP recently had the opportunity to take another look at data from the Disappearing West project — this time, to investigate environmental justice in minority and low-income areas. This departure from our typical focus on ecology and conservation recognizes that the continued disappearance of natural areas in the West affects humans, too. In addition to data from the Disappearing West project, we used 2007–2011 U.S. Census Bureau data to assess the cumulative amount of natural area lost in minority and low-income areas in several major western metropolitan areas, including Seattle, Salt Lake City, and Phoenix.

The study, which CAP has summarized in its report, Parks for All: Building a More Inclusive System of Parks and Public Lands for the National Park Service’s Centennial, found that the amount of natural area lost to development in the region disproportionately affects communities of color and low-income communities in the West. In these communities, the proportion of remaining natural area is lower than the state average. The report urges that correcting these types of inequities should be a priority when designating new public lands or expanding existing boundaries. It also lays out policy recommendations for achieving this goal over the next 100 years.

Changes to the landscape around Gillette, Wyoming, are chronicled in an insightful article that explores the political, economic, and social issues associated with disappearing natural areas.

The findings of the Disappearing West project, a collaboration between the Center for American Progress (CAP) and CSP, are reaching an international audience. The Telegraph, a UK newspaper, recently published an article highlighting the challenges that local farmers and ranchers in the Gillette, Wyoming, area have faced as lands have disappeared — and underscoring the resulting social issues affecting this community.

Brett Dickson was interviewed about CSP’s role in the study, stating, “It was astonishing that there had been no comprehensive analysis of how the landscape was changing.”

Our analysis for the Disappearing West project found that forests, wetlands, deserts, and grasslands were disappearing at the rate of a football field every 2 and a half minutes, a change that has led to habitat fragmentation and other ecological issues. Wyoming alone has lost an area the size of New York City over a single decade; on a percentage-wise basis, this state has changed more than any of the 11 states we surveyed. In particular, the area around Gillette has seen the most changes, due in large part to a now-flagging coal mining industry.
