Travis Tanaka is an environmental scientist with nearly two decades of experience working for CDFW. As a marine scientist with the Marine Region based out of the Monterey office, his primary responsibilities include monitoring the California halibut and Pacific hagfish fisheries, as well as collecting data to help manage their take.

Where did you grow up?

Paso Robles. Growing up in Paso really didn’t influence my future with CDFW or my choice to be a consumptive outdoor enthusiast. My influences came from my father and grandfather. My father taught me to be a hunter and responsible gun owner at a young age. My grandfather was a commercial fisherman and introduced me to fishing for various groundfish species. He taught me to appreciate our ocean’s resources.

What led you to a career in marine biology?

While going through school, I wanted to pursue a career in wildlife management or resource law enforcement. However, my path changed following a college lecture where the professor spoke candidly about upcoming job market opportunities and the future of what we might expect regarding job pursuits within the field of wildlife management. He said the reality was that we would find a lack of work in wildlife management, but that there would be upcoming needs in marine science. After that I began taking extra coursework in marine science and fisheries. Since I’d grown up fishing with my grandfather, I already had a vested interest in fisheries and so taking additional coursework was easy. I had to rethink my interest in resource law once I realized I wouldn’t be able to pass the vision exam.

Tell us about your current research.

I am a staff member on the Northern/Central California Finfish Research and Management Project where we monitor and conduct research on state-managed Finfish species (e.g. California halibut, surf perch, smelt and Pacific hagfish.) My role is to work on California halibut and Pacific hagfish.

For halibut, I monitor the fishery within Monterey Bay. This includes sampling the Monterey area commercial hook-and-line fishery for length distribution and age composition. Early on, I used to go to recreational launch sites and sample the halibut catch from sport anglers. The California Recreational Fisheries Survey (CRFS) program has a great handle on the recreational fishery now, so I put my focus on the commercial end. I also lead the processing for all halibut otoliths our project collects through sampling for ageing. Otoliths, also known as ear bones, are a hard, bony structure important to the fish’s sensory system. Each year, the fish will add a layer, similar to tree rings. I am one of two readers of all halibut otoliths sampled by CDFW staff. To date, we have aged 4,000 California halibut. This age-at-length dataset is one of several datasets that were incorporated into our latest stock assessment. Our project has been collecting halibut data since 2007.

In 2008, I began sampling the hagfish fishery out of Moss Landing to monitor and increase our knowledge of this remerging fishery. I developed a count-per-pound metric to sample live hagfish at the dock. Live hagfish are impossible to measure due to their movement and slime production. Hagfish can’t be sexed externally. To get an estimate of average weight or size, we randomly fill a bucket with hagfish, weigh the bucket and then count back the contents. If this is done repeatedly throughout the tank, we can develop an estimate for average weight. If the average count number goes up, then the fish are smaller per count, and vice versa. The ideal count is around four fish per pound, based on market demand. We then document the average size of retained hagfish and collect life history information, as well as information on the market and its participants.

During a short period in the early 1990s, the Pacific hagfish fishery in California flourished to satisfy an export market for hagfish skins where they were used to create expensive leather-like products, such as boots, bags, wallets and purses. However, a market-induced crash later occurred, and the fishery went dormant. But by 2007, a renewed market demand emerged for the harvest of live hagfish for use as human food.

Part of my job also involves working with fishermen interested in designing new harvest gear. Recently, I worked with fishermen who wanted to use barrels as a new trap type for the take of hagfish. After the fishermen secured experimental gear permits, our project evaluated their new gear design. With assistance from a colleague, we performed the necessary observation trips to collect data on interactions and bycatch. At the same time, we also collected lab samples to document sex ratios and the spawning maturity of hagfish caught by these traps. Once all of the results were in, we approved their new trap type that will improve quality-of-catch, reduce the number of traps on the seafloor, and ultimately be a viable option to existing trap gear.

What are Pacific hagfish?

Pacific hagfish are primitive, spineless, deep-sea fish that lack jaws, true eyes or a stomach. They live in muddy sea floors. Hagfish dine by scavenging dead or dying fish and marine mammals. They enter their prey through any existing hole or orifice they can find, or by creating a new hole via their two pairs of rasping jaws. Once inside, they tear the flesh from the carcasses as they devour their prey from the inside out. When stressed, their defensive mechanism is to overwhelm any prospective predators by exuding a thick viscous slime. This behavior is the reason hagfish are commonly called “slime eels.” Today, Pacific hagfish are caught and sold for human food, and much of the harvest is shipped to markets overseas.

What is a typical day like for you at work?

It depends on if my work day is during my field season or not. My halibut field season runs approximately May-October. Hagfish work is year-round but is significantly slower in the winter. During the field season, halibut sampling occurs in the morning and then I spend the afternoons in the office editing commercial fishing receipts, entering data, or processing halibut otoliths for ageing. Local hagfish sampling occurs in the morning. Once per month I travel to Morro Bay and Port San Luis to sample the Pacific hagfish fisheries in those ports. During the halibut off season, the average day is spent in the office working on the backlog of halibut otoliths, keeping up with landing receipt editing or addressing any pending issues. I spend a significant amount of time answering questions from commercial fishermen and recreational anglers.

What is the most challenging aspect of your job?

The most challenging aspect of the job, for me and for many others in CDFW, is balancing the needs of the resources (halibut and hagfish) with the needs of those people that use it. Within the group that utilize a fishery, there are often conflicts due to allocation between the recreational and commercial sectors (although not for hagfish, for which there is no recreational fishery). Thus, I am required to spend a significant amount of time answering questions from commercial fishermen and recreational anglers over a broad range of marine resources questions. As a CDFW environmental scientist, I must consider and balance the ramifications and consequences (biological, economic, social) of regulations and management actions.

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

It’s not really a surprise, but if I were not a CDFW scientist, I would be working as a commercial fishermen and hunting guide. I have also created some fishing tutorial videos on “Recreational Crabbing” and “Rockfish and Lingcod Fishing Tips and Tricks.” All are now posted on CDFW’s website and have nearly 40,000 views!

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.

CDFW Senior Environmental Scientist Alisa Ellsworth supervises the Inland Desert Region’s Northern Lands Program. Based out of the Bishop office, Alisa oversees 10 employees who perform a wide variety of activities including land acquisition planning, coordinating mitigation for incidental take, and managing over 120,000 acres of state ecological reserves and wildlife areas in Inyo, Mono and San Bernardino counties.

A Central Valley native, Alisa grew up in Visalia. She attended both undergraduate and graduate school at Fresno State, where she completed a bachelor’s degree in botany in 1993 and a master’s degree in biology in 1995. Her thesis focused on vernal pool ecology in Madera County.

What inspired you to become a biologist?

My interest in science first started in high school when I had to do an insect and plant collection for my biology class. I really enjoyed learning how to identify things in nature. When I started college, I was naturally drawn to biology courses and my path was set. I met a group of people that liked to go out botanizing and birding on the weekends and a whole new world opened up for me.

My first wildlife job was in 1992 with Pacific Southwest Research Station, estimating the density of spotted owls in Sequoia National Park. This is where I learned how to hike at night using a compass and topographic map, as there weren’t GPS units back in those days. The work also involved gathering vital rate data (reproduction and mortality) as well as characterizing diets from regurgitated pellets. In 1993, I spent an amazing summer working for the US Forest Service. I hiked all over the Sierra National Forest, mapping vegetation types and looking for rare plants.

How did you come to work for CDFW?

I worked as a scientific aide for the Habitat Conservation group in the Central Region for a year and a half when I was in college. After I graduated, I began working as a private consultant until 1996 conducting rare plant surveys, wetland delineations and revegetation projects. Around that time, I caught the travel bug and applied for a research assistant position focused on field studies of the guanaco, a South American wild camelid related to the llama. This took me to Torres Del Paine National Park in the Patagonia region of southern Chile, where I worked on guanaco reproductive strategies, spacing strategies and movement. We radio collared young guanacos (called chulengos) and monitored for survival and cause-specific mortality. This involved watching a mother give birth to her baby and then soon after running in and grabbing the baby and quickly putting a radio collar on it. Most of the mothers were pretty mild mannered, but one tried stomping on us and spit all over us, which was quite smelly!

Afterward, I joined the Peace Corps and stayed in Ecuador until 1999, working on environmental education projects in schools. When I returned to the United States, I worked briefly as a consultant again, and then took an associate biologist position with Caltrans in Fresno. When a position opened up in CDFW’s Bishop office, in the streambed alteration agreement program, I jumped at it. I was hired in 2001 and have never wanted to leave Bishop since.

Over my career with CDFW, I have managed the X9B and X9C deer zones, the Owens Valley tule elk zones and the White Mountain bighorn sheep hunt zone. I have collected and analyzed wildlife population data for upland game birds, mule deer, tule elk and Nelson bighorn sheep. I’ve provided harvest recommendations and direction for population management of those game animals. Since 2008, I’ve been with the Lands program, working on acquisition projects, writing grants and working with the Wildlife Conservation Board and other non-governmental organizations on projects of shared interest.

We sometimes say that the Eastern Sierra is “the most beautiful part of California you’ve never seen.” What is unique about this ecosphere?

The Eastern Sierra is comprised of mostly public land with very little development compared to many other areas around California. This allows for intact wildlife populations to exist in vast expanses of native habitat. For example, the federally endangered Sierra Nevada bighorn sheep can be found in the high alpine environment in the summer months. They then move downslope in the winter to take advantage of available food not buried under snow. More than 600 bighorn in 13 occupied herd units can now be found in the Sierras, compared to 1995 when there were only 105 left after being devastated from diseases transmitted from competing domestic livestock in the high alpine meadows.

The sheer beauty of the tall mountains and the abundance of wildlife make it a truly special place. I enjoy hearing the tule elk bugling in the fall evenings near the Owens River. If you really want a treat, you can wake up before the sun rises to go observe the greater sage grouse congregate on their leks (meadows or barren areas with little cover) during the spring breeding season. The males put on quite a display in hopes of attracting a female by puffing out their chest, inflating air sacs and making unique sounds that I equate to drops of water.

What kinds of projects are conducted on the reserves and wildlife areas you manage?

Our activities are quite diverse, including managing water rights and grazing, controlling invasive species and performing various wildlife surveys. I serve as the lead for the Eastern Sierra bobcat study, which was initiated in 2014-2015 as part of a three-year project to assess current populations in Inyo and Mono counties. Specific data collected during the study include bobcat population size, density and age structure, as well as home range size, habitat selection, prey base and reproduction.

I also am also the lead for the low-elevation mesocarnivore survey project. This involves the use of remote cameras to capture detailed images of wildlife species such as bobcat, coyote and gray fox. The surveys help us estimate the percent of the study area that a species of interest occurs by placing one camera within a 10.4 Km cell and surveying 100 cells over multiple weeks. The data collected provides occupancy of the species surveyed. Capture-mark-recapture surveys can be done using this method with species such as bobcats that can be identified because of their unique coat patterns.

Inyo and Mono counties have been divided into eight study areas using geographical boundaries that the mesocarnivore surveys will be rotated through. Initially, these surveys will provide occupancy and abundance of individual species within each study area. Over time, data collected from the surveys can be useful to identify population trends.

What has been the most satisfying part of your CDFW career?

I really enjoy working with outstanding people who are focused on managing and conserving the state’s most important places and wildlife. I’m particularly proud of the conservation work that’s been conducted for the benefit of the Round Valley deer herd. We purchased several important properties within its winter range in Rovana and Swall Meadows, with the goal of protecting an intact migration corridor for them to move up and down in elevation to and from their winter and summer ranges.

What projects would you undertake if you had unlimited money and resources?

I am passionate about conserving natural areas for the perpetuation of healthy ecosystems and the wildlife populations they support. California is an incredibly biologically diverse state and these places are truly unique. By protecting them, we will allow them to be enjoyed generations to come. My most recent focus has been working to conserve the greater sage grouse through land acquisition and conservation easements. Funding all of the proposed actions in the Bi-State Action Plan for Greater sage grouse would be a dream come true.

Morgan Knechtle is an environmental scientist with CDFW’s Northern Region in Yreka. He works on the Klamath River Project, which has a primary focus of estimating the return of adult salmon and steelhead to the Klamath and Trinity rivers. He is responsible for multiple field projects that manage salmonids in the Klamath River Basin, such as operating adult salmonid counting stations and coordinating adult spawning ground surveys on the Shasta River, Scott River and Bogus Creek, three highly productive salmonid tributaries to the Klamath River in Siskiyou County. Knechtle also assists with adult recovery efforts, which involve collecting biological information from returning adult salmon at Iron Gate Hatchery, and serves as one of CDFW’s technical representatives for the Klamath Dam Decommissioning Project, which involves the proposed elimination of four hydroelectric dams in northern California and Southern Oregon.

Knechtle earned a Bachelor of Science degree in freshwater fisheries from Humboldt State University and got his first job with CDFW as a scientific aide in the Russian River watershed. He was hired permanently in 2000 and spent four years working on salmonid life cycle monitoring stations on the Mendocino coast. Since 2004, he has worked with salmonids in the Klamath Basin, both on the Trinity River and in the tributaries to the Klamath River in Siskiyou County.

Who or what inspired you to become a scientist?

My love for rivers inspired me to become a scientist. During college at Humboldt State University, I was spending all of my free time fishing for salmon and steelhead and came to the realization that I could study these animals and make a living working with them.

The ability to be an advocate for fishery resources brought me to CDFW. CDFW is one of the only places a scientist can work with fisheries and truly be an objective voice for the resource. Many other organizations do not have this luxury.

What is a typical day like for you at work?

It depends on the time of year. During the fall and winter when adult salmonids are returning to the Klamath River, my world is extremely busy running and participating in multiple field projects monitoring the return of these amazing species. During the spring and summer, I spend much more time in the office crunching numbers and writing reports.

My Chinook salmon work focuses on providing information that can help accurately forecast abundance. This enables us to provide fishing opportunities while maintaining enough fish in the river for future generations. My coho salmon monitoring work focuses on providing accurate abundance information to track the status and trends of this endangered species over time.

As a technical expert on the Klamath Dam Decommissioning Project, in cooperation with other technical experts from other state and federal agencies, I help minimize effects to aquatic species inhabiting the Klamath River during the decommissioning phase of the project. Additionally, I participate in post-dam removal planning projects, including creating plans on how to implement the Iron Gate Hatchery post dam removal and coordinate with Oregon scientists on the reintroduction of salmon above Iron Gate Dam, with a goal of ensuring the recovery of salmonids and aquatic species above the project area.

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

Although the project is not yet complete, the Klamath Dam Decommissioning Project has the potential to be the most rewarding project I have worked on. It stands to be the largest river restoration project to ever be completed in North America, and given that status, as one can imagine, the project has a lot of moving parts. The potential benefits to salmonids in the Klamath and the improvements to the health of the river itself could be enormous. The long-term predicted improvements to water quality, habitat availability, natural flow dynamics and restoration of natural processes to the Klamath River will improve conditions, for not only anadromous salmon and steelhead but also the rest of the plant and animal community that depend on the river for part or all of their life history.

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

It is extremely challenging when social and political concerns get mixed in with natural resource management. Working with coho salmon in the Klamath Basin has been very challenging due to its listed status and the fact that their abundance is extremely low.

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

With unlimited funding, I would like to track and monitor the recovery of spring Chinook in the upper Klamath River post dam removal. They are nearly extinct and they are thought to once have been the most abundant species in the Klamath River Basin.

What aspect of working on the Klamath River is particularly challenging or rewarding?

Multiple stakeholders -- which include Native American tribes, federal and state trustee agencies, and freshwater and ocean anglers -- in the Klamath Basin make some aspects of salmon management challenging. However, when progress is made to restore the river, it is also extremely rewarding because you know that groups with very different perspectives have come together, negotiated agreement and reached consensus on difficult issues.

What is your favorite species to interact with or study?

Steelhead trout are my favorite species to work with. Steelhead are the most elusive of the Klamath salmonids and their complex life history make them a very difficult species to study. They are also my favorite fish to catch.

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

The most obvious is for folks to stay in school and graduate from college. In addition, volunteering and interning in their field of interest early in their education is a benefit to get a taste of what the career might really be like.

Josh Bush is an environmental scientist with the Wildlife Management Program in CDFW’s North Central Region. Based in West Sacramento, he is the unit wildlife biologist for Colusa, Lake and Yolo counties. His work includes a multi-herd tule elk project, collared mule deer studies, coordinating the region’s land acquisitions, management of CDFW lands, and numerous resource assessment projects and surveys. He works primarily with elk, deer, bear, dove, pheasant, quail and turkey but dabbles with lions, bank swallows and Swainson’s hawks. His responsibilities include responding to human-wildlife conflicts and providing technical expertise to hunters and the public.

Josh earned a Bachelor of Science degree in Wildlife, Fish and Conservation Biology, with an emphasis in Wildlife Management, from the University of California, Davis in 2007. He started his CDFW career as a scientific aide in 2005, and worked his way up started his current position in 2011.

Who or what inspired you to become a scientist?

I have always been inspired by my dad, Mark Bush; my fondest memories are the many hunting and fishing trips we enjoyed together. My dad taught me everything he knew about wildlife, biology and the outdoors. He was a constant backstop for all my questions and never discouraged my asking them. After a long day in the field, I would come home and grab my taxonomy book to ID any animal we did not recognize. Those early trips evolved into an obsession with wildlife and progressed into a need to understand interactions between species and the role each played in the environment.

It was much later in college and after I arrived at CDFW that I learned that, you can apply science to the outdoors to help understand and ultimately help manage and create more of the wildlife that we all enjoy seeing. I strive to do this every day.

What is a typical work day like for you?

The only thing that is typical about my day it that is it is always unpredictable. I work mostly in my three counties but my job takes me all over the 17-county North Central Region. It’s a healthy balance of about 65 percent field work and 35 percent desk work. Field days are often 14-16 hours long with lots of overnights and varied tasks including setting camera traps, rescuing injured wildlife, visiting potential land acquisitions, running survey transects and capturing and collaring study animals. You could find me one day near Clear Lake tracking elk and then the next day in Lake Tahoe darting deer. Public phone calls and answering emails are a big and necessary part of the job. I like to start and end each week by clearing the phones and answering any emails that fieldwork prevented me from getting to. It is especially rewarding talking to hunters who are excited to get try their luck.

What is most challenging about working with wildlife?

The most challenging things are the hours that wildlife keep. I enjoy sleeping at night but wildlife can make that difficult. While I am still up early and out late to do portions of my job, science is evolving and remote cameras and satellite collars have made getting some normal shut-eye a little more possible.

What is your favorite species to interact with or study?

I have a soft spot for all animals but mule deer fascinate me – they are so hardy and able to live out their lives in some incredibly rough environments. There is nothing better than darting a mule deer, watching its migration via satellite and then picking up the collar after it is released. It is especially rewarding when you see an ear-tagged deer you collared years prior, knowing that it is still out there doing its thing.

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

I am currently working on it. I am the lead on a tule elk project in partnership with UC Davis and the Rocky Mountain Elk Foundation. The project uses both collars and a non-invasive capture/recapture process that features DNA extracted from elk droppings to determine population levels, among other things, in the herds occupying Lake and Colusa counties. We just started year two of a four-year project but it is already the most rewarding and difficult thing I have worked on. This is the first project I have led and, while it is tough managing all aspects, it is rewarding to see the early results and to work with such dedicated people.

We are currently tracking 38 collared elk via satellite and just completed the first year of fecal-DNA collection, which had myself and UC Davis Ph.D. student Tom Batter hiking the interior Coast Range in 100 degree plus heat picking up elk poop. While not the most glamorous work, it is certainly rewarding!

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

California’s Mediterranean climate is characterized by cold, wet winters, which can result in flooding, and hot dry summers, which can result in fires. My dream is to implement large-scale infrastructure projects that work with the climate-related ecology of California. Specifically, I would like to implement riparian setbacks and large wildland burn units as well as study and document the response from wildlife and the benefit to California. Last winter’s rainfall and flooding, as well as the unfortunate large-scale fires that followed, make these projects all the more important.

The Central Valley has lost a large majority of its riparian habitat since European contact. Riparian setbacks are a truly multi-benefit project. Setbacks could benefit flood control by slowing, sinking and spreading out water. They would also increase habitat for native wildlife and increase recreational opportunities for all. An excellent test case in benefit to recreation and wildlife is the Sacramento River. Above Colusa, the river is dynamic -- it meanders with gravel bars, cut banks and oxbows that are teeming with wildlife diversity. Downstream from Colusa the river is channelized with less habitat, wildlife, recreational opportunities and wildlife diversity.

Wildfire is a part of California, as years of suppression created unhealthy forests with high fuel loads, which lead to high intensity large-scale wildfires. These fires can be detrimental to urban areas, wildlife and wildlife habitat. Wildland burn units – large rotating wildland areas that are burned periodically on a rotational basis – can restore some of these native areas, increase the value to wildlife, habitat heterogeneity and fire safety at the wildland/urban interface.

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

My advice is to embrace everything about your potential career. Show up early, leave late, volunteer, network, be available for the jobs others do not want to do. If you are a hunter, get to know the little fuzzy creatures or little brown birds you would normally overlook. If you do not hunt or fish, grab a fishing rod or take a hunter’s safety class and sign up for a CDFW-sponsored hunt. Be well-rounded and let your passion for the job be visible.
