Biologist Matt Meshriy assists with statewide coordination on issues affecting a broad group of species that includes upland game birds. His job also focuses on small game mammals and predators and competitors of upland game species like badgers, skunks, coyotes, and racoons. Meshriy provides support on a range of issues impacting upland game species including regulations, harvest estimates, disease surveillance, habitat assessment and grant research.

Educated at San Francisco State University, Meshriy has an undergraduate degree in ecology and evolution and a master’s degree in animal behavior and physiology with a focus in mammalogy. In 2004, he landed his first professional biology job banding spotted owls for the U.S. Forest Service in Plumas National Forest. His next professional stop was at the University of California, Berkeley, where he was a research associate in a forest pathology and mycology laboratory. There he maintained culture collections and learned to use molecular techniques like DNA extraction and amplification that later helped him in acquiring grants to fund his master’s thesis work.

Meshriy returned to San Francisco State University and taught biology laboratories and conducted field and genetic investigations of the federally endangered giant kangaroo rat in the Carrizo Plain National Monument. His thesis, titled “Kinship associations of a solitary rodent, Dipodomys ingens, at fluctuating population densities,” described behavioral adaptations of this unique species that facilitate population maintenance and dispersal under unpredictable conditions in their desert environment. After earning his graduate degree in 2009, Meshriy worked for the U.S. Geological Survey en route to being hired by CDFW in 2012.

What led you to a career in wildlife science?

First and foremost, I wanted to do something that felt meaningful. As a kid, my dad got me interested in space. He told me about the moon landings and of future missions to Mars. I grew up with Star Wars in the movie theaters. Although I was raised in the urban landscape of San Francisco and the bay Peninsula, I have always enjoyed being outside in the natural world and regularly explored the coastal mountains on my bicycle and the Sierra Nevada once I could drive.

I worked during my senior year of high school and for a year before and while attending college. I was initially interested in astronomy, astrophysics and meteorology but I came to realize that they required more math than I was comfortable with. I started looking into botany as an alternative area of study, and one semester of calculus seemed more do-able than three. As I enrolled in more elective coursework in the biological sciences, I found my way to biogeography and ecology. I’m fascinated by the relationships between organisms and I’m always curious about the ways that larger groups of organisms and systems are constantly struggling to find or maintain states of equilibrium, and how humans and our activities are increasingly affecting these systems.

Why did you apply for the upland game position?

Before applying for the position, I had very much been involved with the field aspects of data collection and processing of biological samples and data analysis. However, I didn’t have much experience or exposure to other areas of public science like policy, regulation and public outreach. When the job opening was advertised, I was leading a crew in field surveys of the federally threatened giant garter snake in the Sacramento Valley. While I enjoyed the physical work, the idea of being exposed to different aspects of wildlife management was appealing.

What’s your favorite part of your job?

In my experience, our collective progress toward solving problems and improving our understanding of issues moves forward in an uneven manner, in bits and spurts. My favorite parts of the job are the occasions when I feel connected to one of those instances of a shift to forward momentum, when new information becomes available or something new becomes possible.

This might be because a needed regulation gains enough support that it is prioritized for development, or a research need is filled through a new grant or collaboration. It’s the ability to see different facets of issues as I progress in my career. For example, how agencies work together to deliver the science that drives the policy. I like seeing how science is adapted to meet the needs of the public and how each agency and partner is involved. There’s not always a map for that process. Sometimes it takes creative thinking.

What should people know about upland game?

The term “upland game” relates to a group of species that are generally widespread in the state. Many upland game species are versatile and adaptable to a broad range of habitats whereas others occupy more specialized or geographically limited niches in California, like the rock ptarmigan and greater sage grouse.

As a group, upland game species and habitats are fairly ubiquitous in California. There are lots of opportunities for wildlife watchers and hunters alike to pursue upland game birds and mammals without having to travel too far around the state.

What advice would you have for young people interested in science careers?

Explore every opportunity that interests you. The more opportunities you can become involved with, the more likely you’ll find things that satisfy you personally and that you can make a living doing. I don’t think people should spin their wheels in internships or volunteer opportunities that don’t interest them at the outset, on the hope of landing a lucrative job that they assume will fulfil them. Instead, find the pursuits that you really enjoy and then figure out how to string together that set of knowledge, skills and experiences into something that is profitable and unique to you over time. For me, the value in casting a wide net is the broad exposure to issues and species and being able to recognize emergent properties or similarities in different areas of biology and the environment.

As CDFW’s statewide pollinator coordinator, Dr. Hillary Sardiñas supports conservation related to bees, monarch butterflies and any other animal in California that transfers pollen between plants to help them reproduce. She works with a variety of partners, including nonprofit organizations and state and federal agencies to come up with new ideas and collaborations for improving pollinator conservation.

Sardiñas earned her undergraduate degree in environmental studies from University of California, Santa Cruz. She went on to study at the graduate level, earning a Ph.D. in environmental policy and management from University of California, Berkeley. She was hired by CDFW in January 2021.

When did you know you wanted to be a scientist?

When I was an undergrad at UC Santa Cruz I worked in the Chadwick Garden, a small organic garden perched above the hills of Santa Cruz. I was taking a summer course on the natural history of birds and practicing my observation skills when I saw a hummingbird nab and eat a butterfly. Up until that point, I hadn’t realized that hummingbirds also ate insects, I thought they only survived on nectar. Making that connection helped me realize I wanted a career where I got to understand what was happening in nature. I started taking more ecology courses and decided to become an environmental scientist.

What was your path to grad school?

During undergrad I got to take an amazing class called Natural History Field Quarter where I traveled statewide surveying plants and animals. It got me interested in the incredible diversity in California. After I graduated, I worked for some native plant nurseries, and I did a lot of seed collection. In learning more about plants and propagation, I discovered some plants weren't producing seeds. I got curious and researched potential causes, which is how I first heard about pollinator decline and the important role pollinators play in natural and agricultural systems. I realized I wanted to work to protect pollinators. I decided to go to grad school to study how to restore pollinator habitat.

What did you do professionally before joining CDFW?

I spent some time working for the Xerces Society for Invertebrate Conservation where I had the opportunity to collaborate with farmers from all over the west, helping them design and install habitat for pollinators. From there, I joined the Alameda County Resource Conservation District (RCD) where I worked with species such as the California tiger salamander, California red-legged frog and Alameda whipsnake. I also helped create a monarch conservation program that became the model for other RCD monarch programs. I ended up working with the California Association of Resource Conservation Districts, the nonprofit partner to California’s RCDs, as their statewide monarch coordinator. In that role I was able to support dozens of RCDs in their monarch and pollinator-related outreach and restoration work.

What drew you to CDFW’s statewide pollinator coordinator position?

My dream since I was a grad student was to work at a statewide level to conserve pollinators. When I heard about this position, I knew I had to apply. The timing for this position couldn’t have been better. It has enabled CDFW to respond to the emerging monarch crisis while also protecting other important pollinators like bumble bees. Pollinators are responsible for 80 percent of all flowering plant reproduction, and 35 percent of all crops depend on pollinators. Conserving pollinators is an incredibly important issue that helps maintain ecosystem function and sustain biodiversity. In the past year and a half, I’ve been able to work at the state level to bring partners together to develop collaborative management actions that benefit pollinators.

What is your job like on a day-to-day basis?

Every day is different, which is part of the fun. But I do have a few focal areas. One of the species I work with the most is the western monarch. CDFW owns properties along the California coast that support monarch overwintering clusters, so part of my job is working to enhance these sites. I’m also helping to increase native milkweed supply from commercial nurseries so we can enhance breeding habitat.

I also support the California Bumblebee Atlas, a community science project that we’re partnering on with the Xerces Society for Invertebrate Conservation. The goal of the Atlas is to better understand the distribution and health of the state’s bumble bee species. We’re recruiting members of the public to help us survey, since the state is so large we can’t cover it by ourselves.

One of my favorite parts of this job is collaborating with other CDFW staff. For example, I assist our land managers with restoration plans and seed mixes. I also support our habitat conservation division by reviewing proposed projects that might impact pollinators and determining how we can avoid or minimize those impacts. I learn so much from all my colleagues.

How important is public outreach in your job?

Outreach is critical, in large part because the public can play a big role in supporting monarchs and other pollinators. People usually understand the importance of pollinators, but not everyone knows all the different species that contribute to pollination such as wasps and bats. I also try to emphasize the importance of other insects, as they contribute to many critical ecosystem processes. Helping people shift to overcome their fear of insects and understand the incredible role they play is important to ensuring their protection. Biologist E.O. Wilson talked about the “little things that run the world,” and I think pollinators are underrecognized for the value they provide. One way we’re working to get the word out is by installing new signs in our wildlife areas describing the role pollinators play in ecosystem function.

What can the public do to help?

Luckily the adage, “If you build it, they will come,” is true for pollinators. Planting native flowering plants creates pollinator habitat no matter where you live, whether in a city or a rural area. It's important to make sure that all plants you purchase are pesticide free so you don’t inadvertently poison the pollinators you’re trying to attract.

I also encourage people to get involved in a community science project. Community scientists help us cover this vast state. Data collected by community scientists helps us assess the status of insect populations and allows us to develop appropriate management actions. There are a ton of different community science projects with varying levels of commitment, so it’s easy to find one that’s right for you.

What advice do you have for aspiring scientists?

Stay curious. I started out with plants, then got really interested in pollinators, and even took a detour where I learned a lot about amphibians. All of these experiences and interests contributed to a more holistic understanding of the natural world. I also think having a vision is important. As I mentioned, I maintained the goal of working on pollinator conservation at the statewide level. With this objective in mind, I made sure to connect with a variety of different stakeholders and maintain those connections. I think this is what has helped me be successful in this position, because collaboration is a really effective and efficient way to accomplish a lot in a short period of time. And pollinators need as much support as possible.

Environmental Scientist Reagen O'Leary monitors wildlife and plant species on CDFW ecological reserves in the Central Valley. She’s part of a small team that helps protect and recover threatened and endangered species and their habitats on about 50,000 acres of CDFW-owned lands. O’Leary studied biology at Fresno State University and held several part-time jobs, including zookeeper at Fresno Chaffee Zoo, veterinary assistant at an animal hospital and scientific aid for CDFW’s Fishing in the City program. She also conducted owl surveys and worked in CDFW’s Lands Unit. Her first full-time position with the state was as an environmental planner for Caltrans. She was hired by CDFW as an environmental scientist in 2011.

When did you know you wanted to be a scientist?

When I was a kid, I enjoyed watching Mutual of Omaha’s Wild Kingdom and Jacques Cousteau documentaries. I was very curious about the natural world and wanted to know how it worked. I was the type of kid who could sit in a field by myself and be entertained by my fascination with the plants and wildlife around me. Growing up, I thought I wanted to be a marine biologist and work with whales and sharks. In my 20s, I worked at a veterinary clinic and realized I liked animals more than people – but not in a clinical setting. That led to my interest in field biology.

What do you enjoy about your job at CDFW?

I love monitoring and taking inventory of the listed species, whether they be plants or wildlife. The wildlife species we typically work with include the blunt-nosed leopard lizard, kangaroo rat species, San Joaquin kit fox, Swainson's hawk and San Joaquin antelope squirrel. I also really enjoy teaching young scientists about the different species and habitats they depend on. I like seeing lightbulbs go off in people’s minds when they learn something new and correlate that knowledge to what they already knew but maybe couldn’t put to words. Young people can be transformed by what they learn, and I enjoy nurturing an appreciation for nature.

What does your job look like on a day-to-day basis?

It depends on the time of year. The field work is varied. For example, we have a long-term lizard monitoring grid that we’ve kicked off for this year that will run in the spring, summer and fall. On hot days we’ll be out in the field early to beat the heat and get back home at a reasonable time. I oversee our annual winter resident bird surveys. I also monitor the status of multiple rare plants on our ecological reserves during the species blooming period. Other duties include setting up camera traps throughout the lands for species detections. We conduct kangaroo rat trapping in the summer, which consists of night work, and during winter we conduct fairy shrimp surveys. Overall, I’ve logged a lot of walking miles in the San Joaquin desert doing all sorts of activities.

As far as day-to-day office work, I coordinate new land acquisitions, write reports, present on our work at conferences, mentor and guide our scientific aids and conduct work funded by grants. I’m the lead staff for coordinating land acquisitions on a Habitat Conservation Plan. I sometimes joke with my colleagues and say, “Who knew we’d need to understand real estate documents to do this job?”

Do you have any recommendations for aspiring scientists?

I would encourage students to be curious about nature and not be scared to ask professionals questions. What I’m discovering with young people is that they sometimes don’t ask enough questions, or they don’t know what questions to ask. Don’t ever think you’re going to learn it all; as a matter of fact, the more you learn, the more you discover what you don’t know. If you are a person with a curious nature, the scientific field is definitely for you. Find folks that like to explore nature and let your curiosity blossom.
