Did you know scientists have been routinely measuring streamflows within Yellowstone since the 1880's?
Streamflow (discharge) is the volume of water that moves past a reference point over a period of time. This data helps answer management questions related to water availability, water quality, ecological conditions, infrastructure design and maintenance, hazards, climate change, and water rights. It also lets visitors know when it’s time to pull out their fishing rod and waders each year.
“Taking streamflow measurements is comparable to taking the pulse of a river. It’s rewarding to think about how the pulses measured in a small wadable creek or river in the park will be propagated downstream and affect the ecological conditions of a nationwide river network. Water not only touches every aspect of our resources and operations in Yellowstone, it moves across the park boundaries and impacts communities and ecosystems several thousand miles away.” - Erin White, Hydrologist
Did you know Yellowstone collects data to understand impacts from increased visitation in the backcountry?
Employees like Alex map resource impacts like social trails so park managers have the data they need to make informed decisions about backcountry site management, restoration, and improvements.
“Every visitor has an impact on the park, some larger than others. When you multiply that by thousands of backcountry visits each year, popular areas of the park can be inadvertently loved to death. Monitoring these impacts is the first step towards remediating them." - Alex Zaideman, Backcountry Monitoring Lead
Did you know Yellowstone maintains the oldest, continuously operated weather station in Wyoming, which dates to 1894?
Today, employees like Ben maintain a network of climate stations to study the variability of meteorological data across different elevations of the park. With hotter temperatures and 30 fewer days per year with snow on the ground than in the 1960s, park planners are looking for proactive ways to protect its people and resources.
“A warming, drying climate not only impacts park resources, but how you enjoy the park too. This summer we’ve had smoky skies for months and even had to close some places to fishing because the water was too hot.” - Ben Banet, GIS Technician
Employees like Mark deploy and maintain an array of thermistor (temperature) data loggers often placed in the near-boiling, acidic runoff channels of hot springs and geysers across the park. The data collected over time is analyzed for patterns, which help us determine a variety of things like eruption intervals or if nearby features may be connected underground.
“It’s interesting to see how hydrothermal activity in certain features change over time. We’re always learning something new, and sharing that information with folks I meet on the boardwalks is one of my favorite parts of the job.” - Mark Wolf, Physical Science Technician
Did you know Yellowstone surveys wetlands throughout the park to monitor amphibian populations?
Species like Columbia spotted frogs are an “indicator species” because they are sensitive to ecosystem changes and need shallow ponds for breeding. Employees like Jana document their presence, or lack thereof, to signal larger changes taking place in the Greater Yellowstone Ecosystem.
“They often go overlooked in a park full bears and wolves, but amphibians tell us so much about the health of an ecosystem. They are the canary in the coal mine.” - Jana Cram, Lead Biological Technician, Greater Yellowstone Network
Did you know that Yellowstone is an interagency partner of the Greater Yellowstone Ecosystem Whitebark Pine Monitoring Program?
Since 2004, employees like Dani have monitored tree health, recruitment, and its decline across the ecosystem due to ecological effects from nonnative blister rust, native mountain pine beetle, and wildland fire. To inform the restoration strategy for this “Threatened” species, Yellowstone is expanding monitoring to more sites across the park.
“Whitebark pine is important for retaining snowpack to slow spring runoff and its seeds are a key food source for birds like the Clark’s nutcracker and mammals, including grizzly bears. The data we collect will help inform management decisions like intervention, active protection, and possible restoration.” - Dani Yashinovitz, Biological Science Technician.

Did you know Yellowstone partners with nine state and federal agencies to monitor volcanic, hydrothermal, and earthquake activity in the Yellowstone region?
Known as the Yellowstone Volcano Observatory (YVO), employees and partners like Jeff work to better understand what’s happening beneath the ground to forecast imminent hazardous activity. P.S. There are no signs of the volcano erupting anytime soon!
“One example of innovative YVO research is by University of Utah using nodal seismometers. They allow us to 'see' how the ground moves in three dimensions over time and in relation to other events, like geyser eruptions. Maybe one day we’ll be able to predict geysers like Steamboat.” - Jeff Hungerford, Geologist
Did you know Yellowstone has a specialized Thermal Area Preservation Program (TAPP) team who safely removes litter and documents resource impacts in thermal areas?
During summer 2019 alone, TAPP team members like Megan removed 438 hats and 16,404 pieces of litter in thermal areas. The data they collect is used to guide management decisions in order to better protect these natural resources for the future.
"Reach into your pocket for your camera, and out comes a stray wrapper along with it. A brief gust of wind, and say bye to your hat. Most people know not to throw things into hot springs, but many of the impacts we're seeing seem to be accidental. So, hold onto your hats!" - Megan Norr, Geothermal Monitor
Did you know Yellowstone restores wetlands in the park?
When roads are updated, park employees like Heidi coordinate with the Federal Highway Administration to document existing roadside wetlands, determine how future road projects will impact them, and propose how to mitigate those impacts by restoring other disturbed wetlands of the park.
"Restoring wetlands means protecting my two favorite things, water and plants. I’ve worked in Yellowstone since 2002 and I’m still amazed by the diversity and frequency of wetlands on the landscape. It’s not at all a dry place." - Heidi Anderson, Wetland Ecologist
Did you know Yellowstone has a native plant nursery and greenhouse?
When a road project has been approved, employees like Sam will survey the area and collect seed from native plants. A portion of the seed is sowed in the greenhouse during the spring, and the seedlings grow through the summer. When a construction project is finished, the plants are brought back to the area where they were collected to rehabilitate the disturbed areas.
"Revegetation is an important part of road improvement projects, aesthetically and ecologically. By collecting seed from a project site, growing them in our greenhouse, and transplanting them back to the project site, we can get a jump start on the rehabilitation. This keeps invasive weeds from taking hold and improves habitat for animals and insects in the park." - Sam Reid, Biological Technician
Did you know Yellowstone has a vegetation monitoring program?
Scientists like Stefanie inventory, monitor, manage, and conduct research on the 1,386 native plant species and 225 non-native plant species documented in the park. This program allows us to see increases or decreases of invasive species and their impact on native flora, as well as the effects of climate change.
"Most visitors come to see the iconic wildlife and geysers that make Yellowstone famous, but what would that visit be like without the beautiful wildflowers, the towering trees, and the sea of sagebrush that make the valleys so spectacular? Plants provide food and habitat for all manner of wildlife from bison to insects, wolves to birds. I love the diversity and beauty of plants and the intricate role they play in the ecosystem; they make me smile every day." - Stefanie Wacker, Vegetation Ecologist
Did you know Yellowstone uses an underwater remotely operated vehicle to study the spawning habits of invasive lake trout in order to eradicate them?
Park scientists locate spawning beds deep in Yellowstone Lake by tagging select "Judas fish" with radio transmitters and tracking their movements. Once we know where they spawn, employees from the NPS Submerged Resources Center like Dave Conlin dive in to document the spawning beds with photos and video.
"Diving in the lake is cold and difficult. Water temperatures can be near freezing. That means you wear thermal protection under your drysuit and a lot of lead weight to offset it. Climbing into the boat with all that weight at an elevation of 9,000 feet leaves everyone gasping for air. But it's 136 square miles of the park that few get to experience above the water, let alone dive in." - Dave Conlin, Submerged Resources Center Chief

Did you know Yellowstone partners with the U.S. Citizenship and Immigration Services to host naturalization ceremonies?
Since 2014, the partners and Judge Carman have welcomed 248 new U.S. citizens from 59 countries around the world after taking their Oath of Allegiance in the park.
“Performing the naturalization ceremony has been the highlight of my Judicial career. Hearing the stories of these world citizens who have sacrificed and worked for years to join us as citizens of our United States should remind all of us, that despite our tribulations, we remain a beacon of hope to much of the world.” –The Honorable Mark L. Carman, U.S. Magistrate Judge
Did you know Yellowstone hosts nearly 3,000 volunteers each year?
Individuals and organized groups contribute to a combined yearly total of 80,000+ hours valued at $4.8 million in various ways. Some groups like Warfighter Outfitters have long-term relationships with the park, and rangers like Michael work alongside combat veterans to remodel barns, re-roof backcountry patrol cabins, and build horse corrals. In total, nearly 300 servicemen and women from the organization have contributed 190,000+ hours of volunteer labor since 2009.
“It’s a privilege to work alongside these groups of men and women that continue to serve their country. Not only do they get to explore the park while they are here, they head home knowing their work will leave a lasting fingerprint on the park for generations to come.” - Michael Curtis, Park Ranger
Did you know Yellowstone manages a lost and found?
If you're one of the 10,000 calls or 11,000 emails the park receives each year, then you've probably already spoken with one of the folks in our Visitor Services Office. In addition to answering questions, they also organize the 3,000+ lost items we receive each year. Some of the more interesting items have included a tabby cat named "Groovy," a bearded dragon, a tattoo kit, a half-on toolbox, a prosthetic leg, and this "unicorn pelt" jacket and oversized cartoon skunk stuffed animal.
"Calling someone and letting them know you found their wallet or camera, you can tell how relieved and appreciative they are. It's definitely the most rewarding part of the job." - Sara Fleming, Visitor Services Specialist
Did you know Yellowstone predicts Old Faithful eruptions?
Old Faithful has been a top attraction of Yellowstone since the park was established nearly 150 years ago. After each Old Faithful eruption, rangers predict when the next one will be. From over 100 years of recording data, we know if an eruption is longer than 3 minutes, it will be 95 (+/- 10) minutes until the next eruption. If it's under 3 minutes, then it will be 66 (+/- 10) minutes until the next eruption.
"People come from around the world to see Old Faithful, and I help facilitate that. It's a fun part of the job. Seeing a person's reaction to Old Faithful for the first time never gets old." - Phil Officer, Park Ranger (Interpretation)
Did you know Yellowstone researchers study people in the park?
Park staff like Jenni use a variety of tools, including trail counters, to learn more about visitation in popular areas of the park. While these trail counters might look like small cameras, they actually collect data by detecting body heat as people pass by them on a trail. This data helps us understand when sites are most crowded, how trail use changes throughout the year, and ultimately informs park management when making decisions regarding visitor use at a site.
"When visitors see us in the park and ask what we are studying, they are often surprised to learn that it is them. Sometimes they suggest people must be boring subjects. Far from it - people are fascinating! I find it rewarding to collect information that helps to both improve the visitor experience and protect park resources." - Jenni Burr, Outdoor Recreation Planner

Job titles can include public affairs specialist; public information officer; visual information specialist; digital communications specialist; audiovisual production specialist; writer-editor; technical writer-editor; exhibit specialist; media specialist and more.
Did you know Yellowstone has over 3 million combined social media followers from around the world?
Park employees like Ashton create and share content about park resources, current conditions, employees, incidents, and projects with the intent of building a vibrant virtual community of stewards and providing opportunities for people to interact with park employees and each other.
“Sure, sharing pretty pictures is fun, but we also strive to engage in dialogue and foster stewardship through social media campaigns like the Yellowstone Pledge. By highlighting the park from many perspectives, we hope to help you discover your own connection to Yellowstone!” - Ashton Hooker, Digital Communications Specialist
Did you know Yellowstone designs and manages visitor publications?
From the lesser known “Tree Mortality” site bulletin to our popular “unigrid” park map, employees like Miles ensure that visitors to Yellowstone have the information they need to make the most of their trip.
“Between the [roughly] 85 publications we keep updated, we hand out over 2 million copies combined each year. It’s rewarding to be a part of a program that touches nearly every person that visits Yellowstone.” - Miles Barger, Publications Program Manager
Did you know Yellowstone partners with academic institutions on a variety of research and education projects?
To highlight the years of research on microorganisms that thrive in geyser runoff channels, employees like Virginia and our partners at Montana State University recently developed a new interpretive exhibit at Echinus Geyser supported by funding from the National Science Foundation.
“Norris is one of the most dynamic geyser basins in the park, and we’re excited for this new opportunity for people to learn about an often-overlooked resource. If your travels take you to Norris, don’t forget to stop by the Back Basin and check out the new exhibit!” - Virginia Warner, Media Specialist
When employees like Jake shoot photos and video or record audio for media projects, the public domain content is available for anyone to download and use. So, if you need a video clip for that class project or a photo for your living room, we’ve got you covered.
“I’m fully aware how lucky I am to share Yellowstone with people through photos and video. My favorite project I’ve worked on has been #WhatWeDoWednesdays. Highlighting my coworkers and the work that goes into keeping this park running has been a great learning experience for me. Hopefully everyone enjoys it as much as I have!” - Jake Frank, Audiovisual Production Specialist
Did you know Yellowstone takes the lead in writing, designing, and maintaining over 300 outdoor exhibits and 10,000+ square feet of indoor exhibit space?
Park employees like Bianca work with contractors, researchers, park partners, and park subject-matter experts to encourage visitors to learn something new each time they visit with engaging and up-to-date exhibits.
"My role is to help bring Yellowstone's rich cultural and natural history to life for all who visit. Thanks in great part to partner funding, we're able to provide site-specific interpretation of park resources throughout the park. It's always incredibly fulfilling to see people inspired by one of the park's many exhibits." - Bianca Klein, Exhibit Specialist
Wildland & Structural Fire
Learn about NPS careers that focus on wildland and structural fire. Job titles can include fire ecologist; dispatcher; fire management officer; fire management specialist; wildland fire operations specialist; wildfire operations technician; forestry technician and more.
Did you know Yellowstone work to create defensible spaces in the park?
Fire is an important part of Yellowstone's ecosystem, but we also work to protect human lives and the park's developed areas from fire.
In order to create a defensible space, hazard trees are trimmed or cut down, and usable wood is given to firewood permittees or district rangers for various projects. Leftover fuel is stacked and burned when the fire danger is low. These proactive measures minimize the fire intensity, should a wildfire threaten the area.
"Many people don't realize there are nearly 2,000 structures in the park. In addition to actively managing wildfires, we proactively reduce fuel by creating defensible spaces around all of the structures in the park." - Becky Smith, Fire Ecologist
Did you know Yellowstone has a special team of dispatchers to handle wildland fire, major search and rescue, and aviation activity in the park?
When the 2020 Lone Star Fire was first reported, employees in the Emergency Operations Center (EOC) like Ed coordinated the aircraft involved in sizing up the fire, worked to locate and evacuate backcountry campers, and ordered the resources to manage the fire.
"The variety of situations I get to be a part of as a dispatcher makes the work exciting. In a single week, I will work with Life Flights, air tankers, neighboring dispatch centers, wildlife tracking flights, smokejumpers, as well as our own park's firefighters, search and rescue responders, ambulances, and rangers." - Ed Folts, Dispatcher
Did you know Yellowstone has a structural fire department?
With over 3 million square feet of structures, including 800 buildings on the National Register of Historic Places, there's no shortage of buildings to protect. The majority of structural fire work consists of preventing fires rather than fighting them, but members of the team participate in controlled, live-fire training to be ready when things go wrong.
"The fire service is constantly improving. New technology and techniques have allowed us to make the historic buildings of the park safer than ever. We do our best to make sure that they'll be here for future generations to enjoy." - Britton Gray, Structural Fire Chief
Did you know Yellowstone actively works to protect nearly 2,000 structures in the park from fire by creating defensible spaces?
One of the new tools we're using in this fight is called a "masticator." This machine changes a forest's fuel load by thinning out standing trees and mulching dead and down woody debris. In a recent project near West Yellowstone, one masticator treated 60 acres of dense lodgepole regrowth in three weeks.
"The opportunity to use the masticator in place of chainsaws allowed us to complete this defensible space project at a fraction of the time and cost. We're finally gaining some ground, and this project represents the future of fuels management in the developed areas at Yellowstone." - John Cataldo, Fire Management Officer
Learn about NPS careers that focus on wildlife. Job titles can include biological science technician; natural resource specialist; wildlife biologist; fish biologist and more.
Did you know Yellowstone uses GPS collars to study cougar populations in the park?
During the winter when tracks are easier to follow, employees like Dan will track, dart, take health and body measurements, and place a collar. The data collected helps us learn about their abundance, food and habitat needs, activity patterns, interactions with prey, and how they compete with wolves and bears.
“We’re constantly learning about the cougar’s ecological role in the Greater Yellowstone Ecosystem and how to better coexist with these large, secretive carnivores.” - Dan Stahler, Senior Wildlife Biologist
A priority of Yellowstone is to maintain healthy, functioning ecosystems: not just on land, but in the water as well. Yellowstone cutthroat trout are a major part of food webs in the park, but they have been in decline due to predation from introduced lake trout. That's why we put out more than 6,000 miles of gillnet each summer and catch hundreds of thousands of lake trout in order to reduce the long-term extinction risk and restore the ecological role of cutthroat trout.
"If the Yellowstone cutthroat trout were to disappear, and we were to allow the lake trout to thrive within the lake, many of the animals that depend on the cutthroat trout would also be displaced or gone." - Todd Koel, Native Fish Conservation Program Leader
Did you know Yellowstone is working to install bear-proof food storage boxes in all 2,000 frontcountry campsites?
Bear boxes improve visitor safety and reduce the chances a bear or other animal gets human food, which often leads to their removal in management actions. Over the last 10 years, Youth Conservation Corps (YCC) crews and employees like Sam have installed over 1,000 bear boxes. With financial support from Yellowstone Forever, the expected completion date is 2026.
“It's rewarding to help YCC teenagers master new skills like using hand tools, mixing concrete, and team problem solving to place these 400-pound bear boxes. It’s easy to see the tangible results of the crew's hard work and the intangible growth in confidence that comes from knowing they've done something that will help protect visitors and Yellowstone's wildlife for years to come.” - Sam Archibald, YCC Crew Leader
Did you know Yellowstone collects data on what wolves eat?
Once a site has been identified, employees like Doug will ski or hike to the location to collect bone and teeth samples from the prey. The data is then added to the 26 years of research since wolves were reintroduced in 1995.
“Yellowstone continues to be one of the best places to observe predator-prey relationships, and the data we collect helps guide wolf research and conservation all over the world.” - Doug Smith, Senior Wildlife Biologist
Did you know Yellowstone manages people viewing roadside bears?
To protect both bears and visitors, employees like Eric spend over 3,000 hours every summer managing nearly 1,000 “bear jams,” a traffic jam caused by people stopping to watch bears.
“Over the years, we’ve learned that bear management is primarily people management. Our goals are to prevent people feeding bears or getting too close, and making sure they can safely view a wild bear in its natural habitat.” - Eric Reinertson, Bear Management
Did you know Yellowstone has its own wildlife health laboratory to perform disease testing?
In addition to maintaining an archive of samples for the various research projects in the park, employees like Jessica will test up to 1,000 samples collected in the field each year.
"Much of the benefit of having our own lab is savings: in both time and money. Instead of packaging up samples, shipping them to a facility, and waiting weeks to months for results, we can turn around results within a few days." - Jess Richards, Laboratory Manager
Did you know Yellowstone has partnered with Montana State University to study what grizzly bears eat?
While meat is important to grizzlies, most of their diet consists of plants. In 1982, Yellowstone instituted Bear Management Areas (BMA) to restrict human access to areas thought to hold good food resources for grizzly bears. Today, biologists use GPS collars to assess when, where, and most importantly, what grizzlies are eating to ensure BMA's still encompass areas with good food resources.
“Collecting scat tells us a lot about a bear’s diet. When we combine our current data with previous studies, we start to get a better picture of why grizzlies spend time and what foods they utilize in different areas of the park.” - Elise Loggers, MSU Graduate Student
Employees like Erik use specialized equipment and software to create extreme high-resolution images of insects collected as part of the Yellowstone Climate Monitoring Program. These photos are used to help researchers identify specimens down to the species level, while also giving everyone a closer look at Yellowstone's often-overlooked charismatic microfauna.
"We research insects because they are short-lived, sensitive environmental indicators of ecological health. By documenting the diversity and abundance of several poorly studied groups like beetles, grasshoppers, and ants, we gain a better understanding of the critical ecosystem services they provide, like pollination and nutrient cycling." - Erik Oberg, Biologist
Did you know Yellowstone releases trumpeter swan cygnets into the wild?
In 1919, when swans were first documented in the park, they were considered the last population in the lower 48. By 2010, only seven swans were resident in Yellowstone. Employees like Doug Smith are trying to prevent their extirpation in the short term in two ways: 1) incubating eggs in captivity and releasing day-old cygnets near wild adults, and 2) raising cygnets to 100 days old and relocating them to areas with known breeding pairs.
"After seven years of helping nesting pairs and releasing young cygnets, we finally have two new nesting pairs of trumpeter swans in Yellowstone. One of them is highly visible to the public at appropriately named 'Swan Lake,' where swans have not nested since 1966!" - Doug Smith, Senior Wildlife Biologist
Did you know Yellowstone biologists use remote cameras to study wildlife in the park?
These strategically placed cameras help identify and learn about our more secretive wildlife residents, like cougars.
"Using remote cameras is exciting because you never know what’s going to walk in front of them. This tool is great at collecting data to help us paint the big picture of the predators that reside in the park." - Dan Stahler, Wildlife Biologist
Did you know Yellowstone coordinates with Tribal, federal, state, and nonprofit partners to transfer bison to American Indian Tribes?
The Bison Conservation Transfer Program and employees like Chris and Doug have transferred 154 brucellosis-free bison to the Fort Peck Tribes since 2019. Of those, 82 were sent to 17 other Tribes across the country. In partnership with Yellowstone Forever and Greater Yellowstone Coalition, the park plans to more than double the capacity of the program as an alternative to slaughter.
“Not only is the program making history, it’s the right thing to do. Moving bison in coordination with surrounding states gives bison more room to roam and allows people who value bison an opportunity to start new herds across the country.” - Chris Geremia, Senior Bison Biologist
Did you know that Yellowstone studies bison genetics?
Starting in 2018, employees like Ramon collect tissue samples from about 100 animals during the mating season. Using a dart gun from a safe distance, specialized punch darts collect a small skin plug and fall to the ground. After the bison walk away, crews collect the dart and prepare the sample for testing.
“Yellowstone is home to the most genetically diverse bison herd in the world. By collecting and analyzing these samples, we’re able to develop management strategies that ensure the herd remains healthy into the future.” - Ramon Perez, Bison Field Crew Lead
Did you know Yellowstone operates a bird banding station?
Using specialty tools and techniques, birds are captured, studied, banded, and released. As employees like Lauren collect data over time, we can ultimately learn more about how breeding and migrating bird populations respond to changes in climate patterns, fire regimes, and predator/prey relationships. By participating in continent-wide banding programs like Monitoring Avian Productivity and Survivorship (MAPS), we can additionally put the patterns we see during the breeding season in a broader perspective and contribute to the information used to describe patterns in avian populations across North America.
"In total, we've banded 737 birds from 39 unique species. Some rare species include the American redstart, black and white warbler, chestnut-sided warbler, and spotted towhee. Being able to hold and study a bird up-close is truly a unique experience, even for seasoned birders." - Lauren Walker, Bird Biologist
