Featured Scientist

Dr. Andrew Gordus has a unique position, as he is the only staff toxicologist employed by CDFW outside of the department’s Office of Spill Prevention and Response. Based in Fresno, Andy focuses on the detection and effects of poisons as they relate to fish, wildlife and environmental health issues.

Andy was born and raised in rural Wisconsin where he developed a passion for the outdoors, fish and wildlife. He relocated to Southern California with his family at age 14. His passions led him to Humboldt State University, where he earned a bachelor’s degree in Wildlife Management and a master’s degree in Natural Resources Management. He earned his Ph.D. in Comparative Pathology from the UC Davis School of Medicine.

A 17-year CDFW employee, Andy has conducted pioneering research in the area of food safety and whether wildlife could possibly spread dangerous bacteria such as E.coli and Salmonella to farmed crops. He was among the first scientists in California to raise warning flags about dangerous toxicants and serious environmental damage resulting from illegal marijuana grows.

Let’s say you’re at a social event without any work colleagues around. How do you explain what you do for a living?

I tell them I am a toxicologist with the California Department of Fish and Wildlife. My specialty is wildlife diseases and toxicology, and I primarily cover water quality and food safety, but I also have a background in waterfowl and wetland habitat management.

Who or what brought you to CDFW and what inspires you to stay?

Ever since I was a kid, I always had an interest in fish and wildlife so I always wanted to work in some sort of wildlife or natural resources agency. I started with the U.S. Fish and Wildlife Service at the Salton Sea National Wildlife Refuge and lived at Fish and Game housing at the Wister Unit. Back in those days, most of the biologists and managers were Humboldters so I had a lot in common with them. After I graduated from UC Davis, I worked for a private ecological consulting firm in Fresno and got to know the Fresno Fish and Gamers and they got to know me.

In the late 1990s, the department started to hire people above entry level, so I applied and Dale Mitchell hired me as an environmental scientist. And as they say, the rest is history. I get to do a lot of interesting and diverse projects, plus I’ve gotten to meet interesting people and developed both professional relationships and friendships over the years.

There’s been a lot of media and political attention lately on illegal marijuana grows and the damage they cause to wildlife and the environment. You sounded the alarm more than a decade ago. How did you become involved?

In 2004, some of our Central Valley wildlife areas and managed wetlands were required to join the state program that monitors pollutants in irrigated runoff. After the first annual report was released, I noticed dichloro-diphenyl-trichloroethane (DDT) readings at certain locations in the watershed and began to wonder where in the heck that was coming from.

Not too long after that our wildlife area supervisor made a comment to me that our wardens had recently raided an illegal grow in the grasslands region and found DDT containers with labels in Spanish. That’s when it hit me – so that’s where it’s coming from. I went over and talked to then-Captain Nathaniel Arnold and Lt. Specialist Tony Spada and asked if they were finding illegal pesticides in the grows they were raiding. They couldn’t wait to fire up their computers and show me photographs of all the illegal chemicals with labels in Spanish. That was the beginning of my interest about this issue.

In 2012, Dr. Mourad Gabriel published his findings about Pacific fishers being poisoned by rodenticides from illegal grows. This verified what I felt all along – that these grows were causing significant impacts to our watersheds and wildlife. I now give presentations about the impacts to fish, wildlife and water quality and provide a short discussion about the potential harm to human health. I gave this presentation at the 2016 Annual Wildlife Disease Association Conference at Cornell University. During the banquet, a person from Australia approached me and told me that after listening to my talk, he realized he has an illegal grow on his property. This has become an international issue.

What’s the main message in your presentations?

If you are going to smoke pot, make sure it is organic.

Tell us about your food safety and wildlife research.

This all got started in the aftermath of the nationwide E.coli outbreak and scare in 2006 linked to contaminated lettuce and spinach. This was becoming a very serious issue with California produce growers pressured by the public to make sure their produce was safe to eat. The industry was blaming wildlife for contaminating its crops and calling on California growers to eliminate all wildlife and habitat from their farms. Farmers were taking the scorched-earth approach, eliminating riparian habitats and turning their land into moonscapes. This approach was being pushed nationwide, and we feared the country would no longer have any wildlife left if farmers were eliminating wildlife and habitat across the nation.

Working with farmers in the Central Valley and on the Central Coast for many years, I have learned that many of them do enjoy seeing wildlife and having wildlife on their farms. So these produce growers were more than happy to have me answer the question, once and for all, if wildlife was a contamination risk to their crops. Fortunately, we found wildlife is a very low contamination health risk. Our results helped get the Food and Drug Administration to include land stewardship and wildlife and habitat protections in its national food safety rules for growing leafy green vegetables.

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

There are a number of projects I would like to do. I’ve been wanting to collect water samples from the illegal cannabis grows throughout California, as well as from the plants themselves. The general public wants to know if there are any pesticides in their vegetables and fruit, but no one is asking about what poisons they are inhaling into their lungs.

Tell us something about yourself that many people would be surprised to learn.

There are three of us with the title Dr. Andrew Gordus. My oldest son, Andrew, is a professor in the Department of Biology at Johns Hopkins University. A distant cousin Dr. Andrew M. Gordus is a professor at Old Dominion University in Virginia, and, then, of course, there’s myself. My daughter, Margarita, is also a scientist. She works for CDFW here in Fresno as a senior environmental scientist in the Timberland Conservation Program.

Hailey Marie Harrell is an Office of Spill Prevention and Response (OSPR) environmental scientist working as part of the Northern Field Response Team. She graduated from the University of California, Davis, in 2013, with a double major in Plant Biology and English.

Hailey was initially hired as a scientific aid for CDFW’s Habitat Conservation Planning Branch’s Native Plant Program. There, she had the opportunity to do field work with skilled botanists on some of California’s most sensitive plants, conduct census surveys and issue California Endangered Species Act scientific collection permits. She promoted to a permanent role with OSPR in 2016, and has been immersed in the world of oil spill prevention and response ever since.

A relative newcomer to CDFW in terms of job tenure, Hailey has a very fresh perspective on working as an OSPR environmental scientist.

Who or what inspired your love of natural resources?

I’ve spent countless hours in the woods and along waters of this state and I have observed many wonderful and fascinating things within them. I was raised by avid hunters and fishermen who instilled in me an admiration of our truly beautiful natural resources. They hammered home the importance of conservation and taught me to take care to leave places as good as, if not better, than I found them.

How did you come to work for CDFW?

I chose to study plants instead of animals when I got to college because they were a form of life I knew very little about. I was encouraged by a few professors who liked my writing style to take English courses while in college because it is rare to find someone who loves science and also enjoys writing. They saw me as a bridge between technical information and the layperson.

After college, I took a job as a technical writer for a privately contracted aerospace and defense company. After several months, I had learned all the ins and outs of the position and no longer felt challenged. I spent every minute of every 40-hour workweek sitting at a desk in front of a computer screen. In the small bits of time I could manage, I took every opportunity to network with people that were already working in various natural resource agencies. Through these interactions, I got to know some great employees of CDFW who gave me advice and let me do some volunteer work to gain experience for my resume. I eventually landed a scientific aid position with CDFW’s Native Plant Program where I learned my way around the intricacies of state service as I assisted in surveying some of California’s amazing threatened and endangered plant species and issued permits for their protection.

Why did you change your focus from native plants to oil spill response?

I didn’t know if I could love a job as much as the one I had with the Native Plant Program, but knew I couldn’t stay a scientific aid forever so I applied for environmental scientist positions. The OSPR position I have now was the only one of many applications I submitted that gave me a call back. I went into my interview knowing nothing about OSPR except what I had scrambled to learn about it before the interview. I was ecstatic, but at the time had no idea how truly lucky I would be to be offered this position.

Was there a tough learning curve?

The learning curve when joining OSPR was very steep, initially. I think the most challenging aspect was figuring out all the acronyms that are used. In working with the Native Plant Program I scrambled to learn the intricacies of working for a government agency, but the language itself was straightforward because I was exposed to plant terminology throughout college. OSPR was a whole different ball game. For example, it took some time just for me to realize that they were saying “T and E” species (referring to threatened and endangered wildlife) instead of “teeny” species. I would hear the question, “Were any teeny species impacted by the spill?” and would quietly wonder why they were only concerned with little organisms.

In your new position at OSPR, what are your typical duties?

As a first responder to petroleum spills, I work with a wide variety of our state’s natural resources and travel to many beautiful places across California. I get to work closely with our game wardens, the U.S. Coast Guard, private industry and other local, state and federal government agencies. At some spills, I will be the first person on scene and will have to convey my initial findings to my team to determine what level of response we will need to resolve the issue. Sometimes I will be on my own to resolve the issue, sometimes there will be a small group of us working together and sometimes there will be a large contingency of federal, state and local agencies involved to help resolve the incident. Each incident has a unique set of obstacles that need to be overcome. I fill whatever role is necessary to help get the job done as quickly as possible.

This job is also full of surprises. Few days are the same as a first responder to petroleum spills. One minute you think you’ll be in the office all day and the next minute you’re in the car driving to the coast to walk the shorelines and look for oil, or responding to a sunken vessel, or getting to the scene of a truck crash, etc. Weird reports sometimes come in that challenge your knowledge and your strategies for managing problems. It is hard to get bored, and that is one of the many things I love about it.

What has been the most exciting or enjoyable aspect of working at OSPR for you so far?

I think that the most exciting part of the job has to be emergency response. When you go on call you never really know what kind of spills you are going to get. When you get a report of a spill that warrants a response you generally know where you need to go, but there’s almost always some ambiguity regarding what you are going to find. I love working in a position where there’s so much variety.

The networking, training and interagency collaboration are equally enjoyable aspects of the job. For example, one of my first oil spill drills played out a scenario at an oil refinery in San Pablo Bay. It was a large drill with key representatives from the refinery, government agencies, county hazmat, etc. No more than a month later, there was a response to that very same refinery and almost all of those key players I met at the drill were in the command post during a real event. It felt like déjà vu being there and seeing everyone again. It helped put into perspective just how important it is to practice with drills and meet the key players that will be involved during real spills. It builds trust and understanding between those parties involved and helps to demonstrate that we are all working towards a common goal.

You’re still early in your career. Where do you think you will be, professionally speaking, in five years, or 20 years?

I can really see myself sticking with OSPR for the long hall through to retirement. From discussions with friends and family, this really is a unique and amazing position I am in that is unlike any they have heard of before. I need variety to keep myself content and OSPR certainly has that.

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

Having a job where I could contribute to prolonging our natural resources and get out in the outdoors to enjoy them as much as possible has been a dream I did not know I would achieve, but that was my goal and I fought for it. You may have to scrape by and do things that you don’t want to for a while (maybe even a long while), but if you have enthusiasm, determination and a true love of conserving our natural resources, keep working towards your goals. Talk to people, volunteer your time and keep climbing the ladder. Eventually, if you remain persistent, you will find yourself somewhere you never thought you’d be, with a job that you can’t imagine being without.

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.
