Regina Donohoe is an OSPR staff toxicologist working in the Resource Restoration Program. As an ecotoxicologist, she combines the methods of ecology and toxicology to evaluate the effects of pollutants on fish, wildlife and their habitats.

For the past 17 years, Regina has been involved in the remediation of hazardous waste sites, petroleum production facilities and military bases to ensure that chemical contamination is cleaned up to levels that are protective of our natural resources. Regina also provides ecotoxicology support for spill response and assesses the injuries resulting from spills as part of the natural resource damage assessment team.

Regina received a Ph.D. in toxicology from Oregon State University, a M.S. in ecology from San Diego State University and a B.S. in environmental toxicology from the University of California at Davis.

Who or what inspired you to become a scientist?

One summer day when I was a bored five-year-old, my mom asked me to roam our foothills property and bring back every different kind of leaf I could find. It was a clever mom move to keep me busy all afternoon but it is my earliest memory of being fascinated with nature. However, it wasn’t until I met my high school biology teacher that I knew I wanted to be a scientist. Her classroom was a museum filled with skeletons, shells, plants and aquaria of fish, and that class set me on the path to major in science in college. Later, my graduate school advisors shared their passion for science and kept me going.

What got you interested in working with fish and wildlife?

While trying to decide on an undergraduate major, I took an introduction to environmental toxicology class. The professor told the grisly story of the dancing cats of Minimata Bay, Japan during the 1950s. After mercury-laden wastewater was released into the Bay, the fish accumulated it and when the cats ate the fish, they began to walk erratically (or “dance”) because the mercury poisoned their nervous system. It was an “aha” moment. The fact that a single chemical could disrupt an entire ecosystem intrigued and saddened me at the same time, inspiring me to declare environmental toxicology as my major and the focus of my career.

What brought you to CDFW? What inspires you to stay?

It was 1982 when I took a year-long Student Assistant job at the Pesticide Investigation Unit Laboratory of the then-California Department of Fish and Game. The job duties included “creamer patrol,” picking up dead carp from agricultural drains in the Sacramento Valley for pesticide analysis. On a 100° F day, the fish decayed so quickly that when they were scooped up in the net they often exploded into a creamy mess. Another aspect of the job was to conduct bioassays with fish to determine what levels of pesticides in the water were safe. I left the position to study the effects of sewage discharges on the algal populations of Tijuana estuary, meeting my husband while knee-deep in mud. After that, I researched how chemicals could act like hormones, with environmental estrogens altering reproduction in fish. This led to an ecotoxicologist job at the California Environmental Protection Agency. A friend recommended I apply for a job at OSPR and 17 years later, I returned to where I had started.

What is a typical day like for you at work?

My work moves in a couple of different gears. On the slower gear, a ten-year timeframe, I work on remediation of military bases and hazardous waste sites. For each site, the nature and extent of chemical contamination is characterized, the method and level of cleanup is decided, cleanup occurs and then there is follow-up monitoring. For example, we have removed lead bullets from sand dune firing ranges, metal plating waste from salt marshes and crude oil from grasslands. Throughout the multi-year process for each site, I make many visits, read reports, attend meetings and provide comments related to ecotoxicology.

When spills happen, everything shifts into high gear. I pull together information about the spill, plan and conduct studies and assist wherever help is needed. After the spill response ends, the natural resource damage assessment process continues but at a less frenetic pace. I analyze data, prepare presentations and write up results.

In between, I am involved in training and planning, teaching classes on the effects of oil on ecosystems and reviewing literature to be better prepared for the next spill.

Over the course of your career, was there a discovery or an incident that surprised you?

When we were called to respond to the oil spill in Santa Barbara in 2015, we had to plan for fish sampling one day and carry it out the following day. Usually, it might take a couple of weeks to organize such a sampling event. But people from multiple agencies volunteered their gear and help, others quickly purchased needed supplies, experts flew in to collect tissue samples and folks drove many miles to be there on short notice. The sampling day began early, including gearing up in bulky protective clothing to fish on the beach, and ended with a late night of data intake. Everyone brought a positive attitude and worked hard to get the samples we needed to support the natural resource damage assessment. We achieved a near-impossible task because everyone gave it their all. The power of people working together truly surprised and amazed me.

What do you enjoy most about working in ecotoxicology?

California has incredibly diverse ecosystems – deserts, grasslands, chaparral, forests, rivers, wetlands, estuaries and marine habitat. Spills happen all over California, providing me opportunities to investigate impacts to many plant and animal species in a wide variety of habitats and spill scenarios. For example, I’ve been asked: How does diesel affect an old growth redwood tree? What levels of metals are of concern to California Tiger Salamanders? Is brine harmful to ephemeral streams? How does crude oil impact kelp forests? These questions make me scratch my head and think, and learn new things every day. That, to me, is the best thing about being a scientist.

If you had free reign and unlimited funding, what scientific project would you most like to do?

When scientists began to evaluate how oil spills affected ecosystems in the 1970s, they did some interesting laboratory and field studies, but they were limited by the analytical chemistry and assessment methods available at the time. In many cases, oil concentrations in water or tissues were not measured or were simply quantified as total hydrocarbons. Today, we know that oil is a mixture of hundreds to thousands of chemicals that we can quantify at very low levels in the environment. We also have new biochemical and genetic tools that can detect subtle changes in animals in response to oil exposure. It would be great to repeat many of those earlier studies using our current technologies to further our understanding of how oil affects ecosystems, improving our ability to respond to spills and restore habitats following spills.

Do you have any advice for people considering careers in science or natural resources?

Follow that innate scent trail. What makes work seem like play? What keeps you going when you lose the trail? What rewards you at the end of the day? If you have a passion for science or the natural resources, make it your career and be sure to stop and smell all those interesting scents along the way.

Dave Lancaster is an environmental scientist covering Humboldt and Del Norte counties for the Northern Region’s Wildlife Management Program. He has been a unit wildlife biologist for the past 13 years, covering a variety of issues involving birds and mammals including hunting program management, human-wildlife conflict, wildlife disease and welfare, habitat restoration, special-status species protection, population monitoring, research and providing technical assistance to other CDFW programs, agencies and the public.

Dave grew up in eastern Oregon and graduated from Oregon State University, earning Bachelor of Science degrees in both Wildlife Science and Fisheries Science. He has worked as a biologist for more than 20 years, the last 17 of which have been with CDFW.

What led you into a career as a wildlife biologist?

Hunting is a part of life out in rural eastern Oregon, and you start young. This early introduction to game quickly grew into a much wider appreciation for the land and wildlife in general. While there are a number of different jobs that allow a person to satisfy their desire to work out on the land, being a wildlife biologist provides an opportunity to work for the benefit of wildlife and the people who appreciate it.

It is interesting that you have degrees in both Wildlife Science and Fisheries Science. How did that come about?

I wanted to have a career in wildlife management, but most of the work was in fisheries, so I was hedging my bets.

What brought you to CDFW? What inspires you to stay?

Early in one’s career as a biologist, it is often necessary to be flexible and willing to go where job opportunities take you. Like many people in other states, my image of California was crowded freeways and urban sprawl. I never imagined I would make a career here, but when a job came up, I took it, figuring I would not be here long. It was a nice discovery for me that California still has a wealth of wildlife and wildlands, and diverse opportunity to work toward making a material contribution to conservation.

What is a typical day like for you at work?

Unit wildlife biologists have such a wide variety of duties that we typically work on several distinctly different issues in a day, and frequently have our plans changed by new developments occurring in any one of the many tasks we cover. I may on a given morning start to design a study, do a survey or prepare a management plan. Then the phone rings and I am being told a bear broke into a chicken coop, a deer is tangled up in barbed wire or a group of birds has been found dead on the beach – and the day just changed.

What is the most rewarding project that you’ve worked on for CDFW?

There are so many rewarding moments in a biologist’s career, it is difficult to pick out one particular thing. There are those projects that are not enjoyable to work on in the moment, but are very rewarding in the end because of the benefit to wildlife they produce. For example, developing habitat improvement projects and mitigation for impacts from development projects involve a lot of time at the desk, in meetings and conferring with folks with differing opinions and goals. Then there are the days when you are out in woods, grasslands or marshes doing surveys or tagging wildlife. You also get personal satisfaction and thanks from the public for helping a particular animal in some form of distress, such as when a deer or an elk is tangled up in barbed wire and you are able to free it up and send it on its way. On other days, you get the opportunity to help a person who is having some type of problem with wildlife. Of course, for wildlife biologists, any day improving the outlook for wildlife constitutes a good day, but if doing so happens to involve watching, handling or tracking animals, then all the better.

What is your favorite species to interact with or study?

The groups of species that I interact with most frequently are game birds and mammals, typically through managing hunting programs, helping landowners who are having conflicts with wildlife and responding to disease outbreaks. I do not have one particular favorite species. It is a diverse and fascinating world out there, with each one having its own appeal.

If you had free reign and unlimited funding, what scientific project would you most like to do?

Figuring out how to restore and maintain native grassland habitats while accommodating commercial livestock ranching in the shrub steppe of the Great Basin and in coastal montane prairies would be high on the list in terms of landscape-scale conservation priorities. These areas provide important wildlife habitat but the livestock industry is important as well to these rural communities. Providing for both is the key to success in the big picture.

What is it about the work you do that you would most like us to know?

Unit wildlife biologists, as with staff from most of CDFW’s programs, work every day to find practical, effective solutions to complex problems, and try when doing so to satisfy a diverse range of constituents. We have to be practical because the decisions we make and the work we do often directly affects both our constituency and conservation actions carried out on the ground. We have to come up with solutions that actually work, not just in theory; they must work for wildlife, be compatible with landowners’ desired use of their property and be implemented in a cost effective manner. Take hunting as an example: you need to provide for the ecological integrity of the wildlife population being hunted and the habitats and other species that interact with it, and provide for use by the public both in the form of hunting and viewing opportunity, and use hunting as a tool to minimize property damage the hunted species may be causing on private property.

Any advice for people considering careers in science or natural resources?

Get out in the field and read all the quality scientific literature you have time for. The university and on-the-job training are key components to building knowledge and competency, but a lifelong habit of self-education is indispensable. A broad familiarity with the collective knowledge compiled by those that came before us, tempered with extensive and considered first-hand observations from the field, are what make a good biologist.
