Louise Misztal

Executive Director

I’ve worked at Sky Island Alliance for the past nine years, most recently as Conservation Director. I was the principal architect of a regional climate change adaptation workshop series designed for resource managers to advance understanding of impacts on ecosystems and wildlife. This led directly to critical new work to survey, protect and restore fragile spring ecosystems. In 2015, I conducted sabbatical work in Australia, where I met with natural resource colleagues to share methodologies for assessing vulnerability of biodiversity, water sources, and human communities to climate change, and developing responsive science, policy and adaptation strategies. I’m committed to crafting creative solutions to pressing conservation issues and building collaboration among diverse partners. I’m currently principal investigator on a project to collaboratively develop a climate-smart landscape conservation design for the Sky Island Region, focused on springs, streams and grasslands. I hold a B.A. in Ecology and Evolutionary Biology, a B.S. in Microbiology, and an M.S. in Geographic Information Systems, all from the University of Arizona. For my Master’s work, I mapped bi-national conservation priorities for wildlife corridor and habitat protection in the Sky Island region. I am currently Vice Chair of the Desert Landscape Conservation Cooperative, and a member of the Community Water Coalition Advisory Committee, the Art and Environment Network Executive Committee and the Wildlife Conservation Society Climate Change Adaptation Fund Advisory Committee. I love hiking desert rivers and Sky Island creeks to look for birds and swimming holes, and seeking out quiet camping spots with lots of bear sign nearby.

Emily Burns

Program Director

Emily Burns, Ph.D. joined Sky Island Alliance in 2019 with 15 years of research, conservation, and restoration experience. Most recently, Emily was the Science Director for Save the Redwoods League in California. As Science Director, she led the Redwoods and Climate Change Initiative, Redwood Genome Project, multiple conservation planning efforts, and co-founded Redwoods Rising, a public-private partnership to restore more than 70,000 acres of logged coast redwood forest in Redwood National and State Parks. She started the citizen science project, Fern Watch, to track the health of a common understory plant (Western sword fern) along forests of the Pacific Northwest to learn how climate change and recent drought affects this inhabitant of coastal forests. Under Emily’s leadership, Save the Redwoods League established a restoration program, grew the education program to teach more students how climate change affects their local forests, grew a stewardship program to care for thousands of acres of private redwood forestland, and sequenced the coast redwood and giant sequoia genomes to aid conservation efforts for the species. Emily received her doctorate in 2010 from the University of California, Berkeley in Integrative Biology and conducted postdoctoral research on drought tolerance in ferns at the University of California, Santa Cruz where she remains a research associate today. Emily lives in Tucson with her family which includes three rescue tortoises that have been in the family for more than 30 years. You can read more about Emily’s work on DoctorFern.org.

Emily spent her early career studying how plants adapt to drought and is fascinated by the climate extremes within the Madrean Archipelago of the Sonoran Desert. While working in the coast redwood forest of Northern California, she discovered that most redwood forest plants are able to absorb fog water directly into their leaves and stems, an adaptation helping redwood forest flora take advantage of ephemeral water sources and stay hydrated during rainless times of year. She also discovered that the most common plant in the coast redwood forest, Western sword fern, shrinks in size during drought, making this species an excellent indicator of forest hydration and climate change. Emily is eager to learn more about the unique adaptations of the Sky Island species and dedicate herself to protecting the diversity of life, habitats, and water sources of this spectacular region. When she isn’t hiking around in hopes of witnessing reptiles like desert tortoises and gila monsters in the wild, she enjoys doing modern botanical embroidery.

Paulo Quadri Barba

Conservation Director

Paulo Quadri Barba, PhD.  joined Sky Island Alliance in 2020 with 12 years of experience in conservation science and policy projects in both Mexico and the United States. He worked for the National Commission of Protected Areas of Mexico (CONANP) in different areas including climate adaptation policy, and tourism and community development. He is coauthor of the book “Mexico: Un Estado sin Tierra” which analyzes the historical and contemporary challenges of conservation policy in Mexico in the context of land tenure systems. His research work has mainly focused on forest ecology and global environmental change processes in mountain ecosystems, as well as on examining the local socioeconomic impacts of protected areas in Mexico. He has also worked in the islands of Baja California on projects linking species conservation to public health outcomes. Paulo received his doctorate degree in 2018 in Environmental Studies from the University of California Santa Cruz and his masters’ in Environmental Management from the Yale School of Forestry and Environmental Studies in 2012. 

 Paulo was born in Mexico City where since his high school years he started hiking the volcanoes of central Mexico – which he thinks of as his other Sky Islands. Now in Tucson, he is fascinated by the unique diversity of species and habitats of the Sky Islands region and he is excited to get to learn everything about its natural and human history. Paulo’s biggest conservation dream is to see a Sky Islands region where species like wolves and jaguars can roam free and safe again between the two countries he calls home.

Maggie Trinkle

Chief Financial Officer

I returned to The Old Pueblo in 2010 after straying miles from home.  In my twelve years away from Tucson, I worked as a quality and systems manager for a manufacturing firm in Silicon Valley, started my own internet solutions business, and, most importantly, created a few DNAlings.  Once my son and daughter were of school age, I was ready for my next journey and found Sky Island Alliance.  I appreciate the atmosphere of learning and collaboration here, and that I am able to give back to the region that nurtured me into adulthood all those years ago. I have a Bachelor of Science in Business Administration with a major in Operations Management from the Eller College at the University of Arizona.  I provide program support behind the scenes, and mange our accounting and finances. In my free time, I exercise in excess, write, dance, and secretly arrange fresh roses from my garden on my coworkers’ desks.

Sami Hammer

Springs Specialist

I work with Sky Island Alliance’s Adopt-A-Spring monitoring, restoration weekend trips, and spatial analysis and mapping. I have a Bachelor of Science in Biology from Trinity University and a Master’s degree in Natural Resources from The University of Arizona. My Master’s thesis explored how the vegetative, hydrological, and geomorphological characteristics of ephemeral and intermittent streams influence their use by wildlife species of concern. Before coming south, I worked in Wyoming and Idaho as a wildlife technician surveying for species such as Wyoming pocket gophers and pygmy rabbits, as a range technician inventorying range improvements on BLM allotments, and even as a recreation/wildlife intern mapping two-track dirt roads. While living in Tucson as a student, I spent many weekends exploring the Sky Islands. I am excited to continue to work in and learn about this region as a part of SIA. I love exploring new landscapes, starry nights, ridge tops, and the quiet of remote places.

Meagan Bethel

Wildlife Specialist

I was born and raised in Tucson, Arizona; and my passion for biodiversity and interest in wildlife conservation began with riding on my father’s shoulders. Pointing out wildlife, crouching under bushes, and peering under rocks. I learned to love the Sky Island region and appreciate the species that occupy it. But my interest in wildlife conservation started in 4th grade when a Sky Island Alliance employee came to my class to teach us about the ocelot, and I was hooked. I have volunteered with Sky Island Alliance ever since, helping with tracking workshops, checking and analyzing remote camera data. Even conducting my own research projects in High School to better understand the environment around us. I followed my passion for wildlife and habitat conservation all throughout school and I graduated from the University of Arizona in the School of Natural Resources with an emphasis on wildlife conservation and management. In my free time I draw, act in community theater, and am in several Star Wars costuming/charity clubs.

Zoe Fullem

Community Science Manager 

I joined Sky Island Alliance in spring 2020 to lead the Border Wildlife Study in the field. A Tucson transplant by way of the Midwest and Upstate NY, I am already smitten with the Sky Island panoramic vistas, the starry night skies, and the unexpected blooms and fruits of the desert. I received a Bachelor’s degree from Macalester College in Economics and Environmental Studies, which led me to pursue microfinance and urban agriculture after graduation. I then joined the Peace Corps, serving in Panama for two years as a Sustainable Agriculture Volunteer, working with Indigenous Ngäbe cocoa and coffee farmers, and then served a third year as a liaison between the Peace Corps, local host communities, and Panamanian government agencies. Returning to the U.S., I worked as a community lender at Accion Chicago, providing capital and business coaching to historically excluded entrepreneurs. I then attended graduate school at the University of Michigan, receiving an M.S. in Natural Resources, with specializations in Conservation Ecology and GIS, and collaborated on projects involving wildlife tracking, citizen science, and ethnobotany in the Great Lakes region. In my free time I enjoy gardening, hiking, rock climbing, and DIY home projects.
