Laird Henkel is a senior environmental scientist-supervisor with CDFW’s Office of Spill Prevention and Response (OSPR), where he serves as director of the department’s Marine Wildlife Veterinary Care and Research Center (MWVCRC) in Santa Cruz. Laird joined OSPR in 2007 as the statewide oiled wildlife response coordinator. He moved to his current job in 2010. The MWVCRC is the primary care facility for oiled sea otters and serves as a center for research on the health and pathology of sea otters and marine birds.

Laird grew up in Connecticut and moved to California to attend UC Santa Cruz, where he earned a bachelor’s degree in biology. He subsequently earned a master’s degree in marine science at Moss Landing Marine Labs, where he studied the spatial distribution of marine birds on Monterey Bay. Prior to working for CDFW, Laird worked on a variety of research projects with birds including marbled murrelets and snowy plovers.

Who or what inspired you to become a scientist?

I’ve always been inquisitive, and enjoyed science books as a kid. I also spent quite of bit of time with other kids checking out critters living under rocks, and – probably like most kids – thought  Jacques Cousteau (a famous marine explorer in the 70s and 80s) was awesome. But when I left for UC Santa Cruz, I was not necessarily planning on studying science. A variety of factors led me to major in biology and once I was in, I was hooked. 

What got you interested in working with wildlife?

In college, I took some great natural history classes, including one working with elephant seals at Año Nuevo State Reserve, and an ornithology class, which led me to become fascinated with the lives of animals. The summer before my senior year, I assisted on a project assessing mountain goat behavior related to population size in Idaho, and right after graduating I had a great volunteer job working on a remote island in Alaska monitoring diet and growth of tufted puffins. Field biology was fascinating and a great way to see some amazing places, from Alaska to Maine to Costa Rica.

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

I first worked for CDFW as a scientific aid for Senior Environmental Scientist Rob Titus in 1995, working with winter-run Chinook salmon. That was a short-term position. Then I moved back to Santa Cruz and had a variety of other field jobs with birds, earned a master’s degree in marine science, and worked at an environmental consulting firm for several years. One of my other jobs included conducting aerial surveys for marine birds and mammals under a contract with OSPR. Through that work, OSPR seemed like a great place to work and was in the right place at the right time when my current dream job opened up. I feel lucky to have it. I am inspired to stay because of the great work we do!

What is a typical day like for you at work?

I typically deal with various logistical issues—I’m responsible for my staff and for a complicated (and aging) facility. The facility is set up for oiled wildlife response including pools plumbed with seawater and a state-of-the-art necropsy facility (necropsies are the equivalent of autopsies but on non-human animals—here mostly sea otters and seabirds, but we’ve had an occasional great white shark or leatherback sea turtle). But all this logistical work can be rewarding. Planning projects and providing strategic vision for staff allows our team to respond effectively to oil spills, and allows my staff to work on exciting scientific work investigating health of sea otters and seabirds.

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

Our primary role at OSPR is response to oil spills and although we never look forward to them, the experience can be rewarding (albeit stressful). Spill response allows an opportunity to put our training to use and have a positive influence, hopefully making a bad situation better. My first big spill response was the Cosco Busan incident in the San Francisco Bay in 2007, only a month after I started. That was a great learning experience for me. Since then there have only been a few spills affecting substantial numbers of animals, most recently the Refugio spill in Santa Barbara in 2015. All of this work on oil spills is rewarding, especially to see cleaned and rehabilitated wildlife released back into the wild.

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

There are many projects that would be intellectually stimulating and fun, and also a lot of conservation projects in desperate need of funding. But I think one way to have a big influence on recovery of threatened species would be to put more funding into investigating ways to minimize the impacts of corvids (ravens, crows and jays) on threatened species. Through our work on oil spill restoration projects, I’ve seen corvid impacts (corvids eating eggs or young of threatened species) as a common theme limiting recovery of multiple species. Corvids are very smart birds and they’ve done a great job of adapting to and benefiting from humans. Because humans are responsible for huge population increases in corvids, it would be great if we could do something to minimize their impacts on other species. But this is not an easy issue to address – thus the need for more funding.

What is the best thing about being a wildlife scientist?

Discovery. There will always be new things to discover, and that is the whole point of science. 

The world of science and managing natural resources is often confusing or mysterious for the average person. What is it about the work you do that you’d most like us to know?

The natural world is indeed so mysterious! But I guess one thing for non-scientists would be not to let numbers and mathematical formulas scare you. Ecology as a science has become more mathematical over the years, and even we scientists have a hard time keeping up with new statistical methods and fancy mathematical models. Scientific studies should still be done in a way that makes sense – if you can see past the formulas and understand how a study or an experiment was set up, it is usually not too difficult to understand the results.

Is there a preconception about scientists you would like to dispel?

I think one misconception might be that scientists have all the answers. Any good scientist will tell you there is still a lot to learn, and the better you are at science, the more likely you are to acknowledge that we are not sure about a lot of things. Uncertainty is a big part of science, and properly assessing that uncertainty is important. (To be clear: global climate change is NOT something with a lot of uncertainty).

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

Be curious and have an open mind. Science is all about not having pre-conceived biases, and being willing to accept findings that may be surprising or even in conflict with previously-held beliefs.

Stacy Martinelli is CDFW’s wine country wildlife biologist. An environmental scientist based in Santa Rosa, Stacy is assigned to Napa and Sonoma counties where she has worked the past 10 years conducting wildlife research, resolving human-wildlife conflicts and helping manage CDFW’s properties.

Stacy was born and raised in Montreal, Canada. She earned an undergraduate degree in wildlife management from Montreal’s McGill University and a master’s degree in wildlife ecology, also from McGill. For her graduate research, she studied black ducks in Nova Scotia, one of Canada’s Maritime provinces on the Atlantic Coast.

What brought you to the United States?

Work – like every immigrant. I just couldn’t find work in Canada so I answered an ad in an ornithological newsletter looking for help on a waterfowl research project down in Los Banos. I was like, “I’ll do that. That’ll be fun. I’ll just start building my résumé.” It was a six-month contract helping a graduate student from the University of Missouri with some research. The project ended and I thought, “I like California.” That was in 1995.

How did you get to CDFW?

After Los Banos, somebody knew somebody that needed a biologist for the Suisun Resource Conservation District (SRCD) in the Suisun Marsh. I spent three years in that job. I lived out in the barracks on Grizzly Island alongside CDFW employees. It was really a lot of fun. At SRCD, we worked closely with the department as well. So I knew people and how the department worked and I thought I would love to work for the department. I applied for a Habitat Conservation Program job in San Diego in 1988 and spent a year down there as an environmental scientist reviewing projects and issuing permits. I got a transfer and promotion to our Bay Delta Region and worked in our Timberland Conservation Program until 2008 when I got my current job.

What’s kept you in this job for the past decade?

It’s such a great job. I am so thankful for this job. It’s so variable. It’s a good mix of field work, research and monitoring. There’s a lot of hands-on work. Sonoma and Napa counties are really exceptional because there is just high biodiversity here and there is still a lot of open space. I am a little worried about the housing crunch and all the talk to build more housing but there’s still a lot of great wildlife habitat that’s out here. We’ve got the coast in Sonoma. In Napa, we’ve got the beautiful east side with the Knoxville Wildlife Area that’s still pristine. And even here on the west side of Santa Rosa, we’ve got (endangered) tiger salamanders. We’ve got neighbors around them, but they’re still here and that’s really cool. We’re trying to do everything we can to make sure they don’t disappear.

Last October, this region experienced some of the most devastating wildfires in U.S. history. You’ve had more fires this year. What’s been the impact to wildlife?

There was high mortality for sure, especially with the Tubbs Fire last year, which burned so quickly. The species that live here – bobcat, coyote, gray fox, blacktail deer – they’re fairly resilient and adaptable. I don’t worry about them on a population level. They are going to be fine.

I am working on two projects right now looking at fire effects. One of those is in the Knoxville Wildlife Area. This is year three of a camera trap study. It’s a way of measuring the wildlife community with cameras in terms of abundance and presence of different species and the balance among those species.

I’ve got 23 trail cameras spread out there in a grid pattern about a kilometer apart. I’ve got half of my cameras on the west side of the wildlife area and half of my cameras on the east side. The east side burned in July in the County Fire and I lost a bunch of cameras. They just melted. But some survived and I’ve got photos of the flames and the smoke and everything.

The cool thing is I have three years of baseline data so I know what the wildlife community looks like pre-fire and now we get to see what the wildlife community looks like post-fire. We actually talked to Cal Fire at one point about doing a prescribed burn to study this exact thing, and now 6,000 acres are gone as a result of the County Fire.

My hope is that we see a rejuvenation of the chaparral community because that stuff just gets super woody. Deer browse those shrub species and as they age and become woody, they lose their nutritional value. All the new growth is going to provide a wonderful new food source for them. I’m pretty excited about the whole thing.

It sounds like the Knoxville Wildlife Area is a pretty special place.

It’s a very important piece of property. I’m so lucky I get to work on it. It’s huge. It’s 22,000 acres of mostly oak woodlands and grasslands with the chaparral component. There’s not a lot of other public hunting land around here. If you’re a Bay Area resident, Knoxville is the closest place to hunt deer.

The funny thing is when I first started working there I was like, “OK, nothing lives here.” I never saw any wildlife. Maybe I would see a deer or two by the side of the road but even when I explored the backcountry, I never saw much of anything. It was like a dead zone. What lives here? I have no idea.

But we’ve found all kinds of wildlife with our camera study. We found bears, which I thought was cool. We knew there were mountain lions, but we wanted documentation. There are more deer there than I thought. We never used to see bucks. But then I got some cameras up in the high elevations, the mostly inaccessible areas and it was like, “Aha! I know where you are now!” We saw badger. We found roadrunner. We found spotted skunk. These are all species that would be really tough to see in the field. So it’s been really exciting.

Is there a particular project you’ve worked on over your career that you’re especially proud of?

I’m not sure I’ve done that signature project yet. To me, land conservation is the biggest contribution that I think I can make and we as a department can make. They’re just not making any more land. If we don’t get the land, there’s always the risk of development. I’m pretty passionate about land conservation for wildlife. So I’m waiting for that opportunity to be part of locking up a piece of land for the wildlife community – and for the public, too.

What advice would you give a young person thinking about a career in natural resources?

I think the best thing is to do as much field work as you possibly can – especially during your undergraduate studies. Volunteer. Get an internship. Just be active in the wildlife community as best you can.

We have students call us quite often and we hire a bunch of scientific aides. I’ve done a lot of interviews and looked at a lot of résumés. Unfortunately, we see people who have graduated from college without a stitch of field experience. They’ve not done one thing. Start padding your résumé and just be prepared the next couple of years to travel around and do field projects throughout the state, throughout the country, throughout the world. Eventually you will get there. But be patient because you have to suffer some horrible pay and eating Top Ramen for a while before you can latch onto something permanent.

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

I play bagpipes in a bagpipe band. I play with the Macintosh Pipe Band in Larkspur, Marin County, and I go down and practice every week. We compete in the Bay Area, Monterey, and have played across the U.S., Scotland and Mexico. I learned how to play in Canada and I’ve stuck with it ever since. It’s a passion of mine.

Nicholas “Nick” Simpson is a senior environmental scientist (specialist) with CDFW’s Northern Region, based in Eureka. He works in the Timberland Conservation Program helping to manage natural communities on privately owned timberlands. He is responsible for ensuring that timber operations will not lead to significant or long-term negative impacts on aquatic communities. Simpson’s work includes technical support for CDFW timber staff reviewing timber harvesting plans, lake and streambed alteration agreements, threatened/endangered species consultations, incidental take permits, and habitat conservation plans. Nick is also conducting studies to evaluate the effects of timber operations such as water diversions, road construction and riparian zone management on aquatic communities.

Nick earned his Bachelor and Master of Science Degrees in freshwater fisheries and natural resources at Humboldt State University. Prior to coming to CDFW in 2013, he worked in the private and public sectors as a hydrologist and fisheries biologist, where he evaluated past and current timber harvesting effects on aquatic communities on the North Coast.

Who or what inspired you to become a scientist?

My father and grandfather introduced me to fishing and diving at a young age, and I became fascinated with all things swimming. Exploration led to questions, which ultimately formed a drive to conduct scientific evaluations. Later, as a Fisheries major at Humboldt State University, I became intrigued by the extensive network of local salmon-bearing rivers and streams on private timberlands. Under the context of historical and current logging practices, as well as recent salmonid population declines, I wanted to study the effectiveness of conservation strategies being applied in these watersheds.

What is a typical day like for you at work?

A typical day may include a variety of field inspections including proposed timber harvesting plan reviews, sensitive species or lake and streambed alteration agreement consultations, or compliance/effectiveness inspections of completed projects. My day consists of meeting with foresters and other agency representatives at the closest location we can drive to with a truck, then utilizing all-terrain vehicles and hiking to access remote forest locations. Inspections help ensure that fish and amphibian habitat were delineated accurately, and appropriate riparian buffers are clearly flagged in the field. In addition, watercourse crossings are commonly evaluated to assess their appropriateness and functionality and whether reconstruction, removal or maintenance is required. The following day is usually spent writing reports to record my field observations and to support my recommendations.

What is most challenging about your work?

The most challenging aspect of the job is balancing permit review, scientific study/research and landowner outreach. Permit review, in the form of timber harvesting plans and lake and streambed alteration agreements can be intense, especially when timber is selling at a higher price and more permits are in need of review than normal. I find it important to keep a landscape-level perspective, through research and landowner outreach to ensure conservation efforts are maximized in watersheds with critical habitat for sensitive species.

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

I recently completed a pilot study evaluating the effects of water diversion on macroinvertebrates in headwater streams. It was a great experience to generate a scientific study to support protective measures used in Lake and Streambed Alteration Agreements. The project also ended up winning the “Early Career Scientist Best Poster” award at the 2017 CDFW science symposium.

I have also been involved with reviewing multiple logging road crossings and fish barrier projects, which, after execution, have ultimately allowed fish access to formerly blocked habitat. It is always rewarding to facilitate the expansion of salmon range and the restoration of habitat.

What is your favorite species to interact with or study?

My favorite species is Coho salmon. Coho’s life history includes a juvenile winter rearing period, which makes this species highly susceptible to logging impacts such as increases in turbidity and sedimentation. Any recent Coho reoccupation of formerly unoccupied habitats (usually after barrier removal, or stream quality restoration) is the ultimate indicator of the effectiveness of forest conservation and restoration efforts. However, we are still learning about the dynamic aspects of streams and salmon, such as juvenile winter rearing and stream limiting factors.

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

Our website is regularly updated, and is a great resource for those who want to know more about the Timberland Conservation Program. It is located at www.wildlife.ca.gov/conservation/timber.

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

Large woody debris (LWD) is an important stream component for Coho salmon (Oncorhynchus kisutch). In a recent analysis, we found that 73 percent of Humboldt County Coho streams are depleted in LWD due to historical “stream cleaning” (log harvesting from streams) and past logging practices. It would be great to develop a model to assess the best restoration strategies based on stream channel type and condition.

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

I would consider gaining experience in the field you are interested in as early and often as possible. A common misconception in college is that you go to school for four years, graduate, and then obtain your dream job right away. In reality, employers are looking for someone with experience, in addition to the basic academic knowledge. It is worth putting in the time as a seasonal technician or volunteer while in school to gain that valuable experience.
