Scott L. Harris is an environmental scientist with CDFW’s Northern Region, based in Mendocino County. Scott is responsible for monitoring and managing salmonid populations in the Eel River and Mendocino coast watersheds as part of the North Central District Salmon and Steelhead Management Project, a multi-faceted effort funded through the Sport Fish Restoration Act (SFRA). His fieldwork includes counting adult salmon and steelhead through spawning ground surveys and ladder counts at the Van Arsdale Fisheries Station (VAFS), counting juvenile salmonids migrating to the ocean and determining resident trout distribution in the Mendocino National Forest. Much of his time is spent at the VAFS fish ladder studying the biological effects of water releases from the Potter Valley Project (PVP). He also consults on fish passage issues, evaluating man-made structures (fish ladders, etc.) at road crossings to determine whether they are damaged, blocked or in need of cleaning, and whether the design is adequate to meet the need.

What or who inspired you to become a scientist?

The “what” is water. I am fascinated with water, salt or fresh. I grew up in Southern California and spent most of my time at the beach. When I was about 10, I was instantly hooked on the ocean when I first put a mask on and saw what was taking place under the waves. At about the same age, I found a local stream and was mesmerized by the number of animals that lived in and around that stream. Then came my love affair with PBS, NOVA, Wild Kingdom, the local library, etc. I’m guessing a lot of folks went through a similar progression.

The “who” probably started with Carl Sagan, Marlin Perkins (and, of course, Jim Fowler, Perkins’ assistant), my friend’s mom (a science teacher) and my dad (an engineer). Today I am surrounded by many colleagues who feed my interest in science and I would bet these folks are inspirational for many others, young and old.

My fascination with water continues today with my job. However, my work with the department requires the understanding of the physical aspects of water, not just the biological aspects. In stream restoration, it is necessary that one understands hydrology and fluvial (movement of sediment in water) processes.

What is a typical day like for you at work?

If there was a typical day, I would probably quit! There are days when I am greeted at my door by hunters that need a bear or deer validated. When a hunter takes a deer or bear, the animal must be reviewed and then some paperwork is completed indicating that the take was legal. In addition, a tooth must be extracted from bears. The tooth is used to determine age and this information is used as a tool in management of our black bear populations. Sometimes I’m asked to pull a bear tooth in the Safeway parking lot or at the gas station. This is not exactly fisheries but I absolutely believe I am part of a team. Typically, if I receive a call before 9 a.m., I know my day will change and that someone needs help. Many days include a wild card. I wouldn’t have it any other way!

I am one of the lucky ones. During the year, I spend 90 percent of my time in the field. So, 90 percent of the year, I leave my office excited and with a smile on my face, ready to learn something new or hopefully teach someone something new.

What is your favorite species to interact with or study?

For those who know me, they know how important herps and birds are to me. I bring that knowledge to many of my colleagues. However, there are two species that I have a special fondness for: The Middle Fork Eel River summer Steelhead and the Pacific Lamprey.

We conduct an annual free dive/snorkel survey on the Middle Fork Eel River that was named the “Death March” 30 or more years ago. This 26-mile, five-day survey is conducted in the Middle Eel/Yolla Bolly Wilderness located in Trinity and Mendocino counties with the intent to enumerate adult summer Steelhead. Dozens of department employees have been on the Death March over the years and I guarantee that they have yet to forget it. This annual survey began in 1966.

In 2009, I took over the activities at the Van Arsdale Fisheries Station located in the upper Eel River. Through our activities there, Pacific Lamprey became a target species for study. I have been collaborating with two people, Damon Goodman with the U.S. Fish and Wildlife Service and Stewart Reid with Western Fishes, both of whom are known for their background and expertise on Pacific Lamprey. We have all learned some amazing things about Pacific Lamprey. There has already been one “white” paper written from this work and I believe there are at least another two in the making.

What aspect of working on monitoring salmonid populations is the most challenging?

The projects that are most challenging are typically those with numerous stakeholders or interested parties. I have been involved with the Willits Bypass for decades and this project has seen multiple agencies and interested parties over time. Keep in mind, the Willits Bypass was started in 1955, so the number of interested parties could be considered myriad. Another project with a high number of interested parties is the PVP. With the Federal Energy Regulatory Commission relicensing effort underway for the PVP, things are getting interesting.

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

There are a few projects that come to mind, but the one that I will tell you about is more about how I have volunteered my time as a mentor. About 10 years ago, a neighbor introduced me to her son, Bryan. Bryan needed a science fair project. Before we decided on a project, I thought it would be good to involve Bryan in some of the fieldwork we conduct. So, he ended up getting a taste of salmon spawning ground surveys, juvenile outmigrant trapping, backpack electrofishing – he even participated in the infamous Death March.

The project we decided on was, to say the least, controversial. The title of the project was “Why is there no water in Alder Creek.” And yes, this project had everything to do with the effect of pot growing on aquatic resources. We conducted the fieldwork on weekends due to Bryan’s school schedule and we worked on maps and tables in the evenings. This project led to numerous field visits with department enforcement and Bureau of Land Management enforcement. Things got a little hairy in the field. It also led to a few threats over the phone. The bottom line is, Bryan’s project won first place at the state level and he even got to have lunch with retired Governor Deukmejian. I remain in touch with Bryan to this day, I suppose, as a father figure.

What is the most challenging aspect of your career as an environmental scientist?

For myself, and probably for most of us in the department who conduct monitoring, research and habitat restoration, it is resources. Not having resources (money) to implement more of what we are already doing is maddening. The challenge is to be OK with so little help.

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

In, at least, our state’s three largest rivers (Sacramento, Klamath and Eel) I would like to see aquatic habitat (rivers, estuaries, lagoons, vernal pools, etc.) restoration of every conceivable type take place, and as quickly as possible. With the implementation of the restoration would come monitoring the effectiveness of the implementation by evaluating the response by plants, animals and the physical environment.

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

Certainly, education plays a key role when it comes to our natural resources and science. Education also includes get involved in internships and/or volunteering. I have mentored 15 AmeriCorps members, two of whom went on to get doctorate degrees in fisheries ecology.

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.
