California Megadrought
Scott Gediman
Public Affairs Specialist, Yosemite National Park
After a week’s conference in Sacramento CA for the Society of Environmental Journalists, during an unusually severe California drought, a small group of us travelled on to the higher elevations of the Sierra Nevadas to learn about conservation and management in the state’s famed Yosemite, Sequoia and Kings Canyon National Parks. On our first morning, we received a broad background during breakfast before going out to explore this protected wonderland. It was great to hear the extensive commitment to maintaining this glorious park for the benefit of all US citizens – and international visitors.

Key Quote The national parks belong to all the American people. I’m a firm believer in there’s no substitute for going to a national park. –Scott Gediman
A bit about me…. I’ve been here in the Sierras for over 20 years and with the National Park Service for 26 years, Previously, I worked at Glen Canyon and Lake Powell in Arizona and Utah; at Rainbow Bridge National Monument; and at the Grand Canyon. In the past 20 years, I’ve seen much here in the Sierras. Much has happened; and much of that is good,
I thought we’d start with the big picture: park visitation. Kelly Martin talked to you about the prescribed burn in the Ahwahnee Meadow; and Linda Mazzu talked about the frogs, turtles, and other restoration projects. It’s all interesting, and we’re hoping it all fits into the implementation of the Merced River Plan and our overall current park management efforts. Regarding the visitation of the park, this has been a big year for many reasons, including President Obama’s visit this past June. It’s been a big year for national parks overall. “Visit California” and many of the tourism bureaus are seeing huge numbers in San Francisco, in many other urban areas, and in commercial ventures, including Disneyland and Universal Studios. I think more people are traveling, partly due to the lower gas prices, People want to get out and see the country. Not only is Yosemite busy, but we see a huge amount of visitation in National Parks across the country – including at Grand Canyon National Park, Rocky Mountain National Park, and parks like Mesa Verde National Park, Arches, Canyonland National Park, which is wonderful. We’ll never say that there are too many visitors.
The national parks belong to all the American people. I’m a firm believer in there’s no substitute for going to a national park. I’ve worked with Ken Burns on his video and was here when the President came. Anyone can click on the Internet for great videos and photos; but really there’s no substitute for being here and hiking on our trails. In fact, the President had never been here, and he just had many great moments. His helicopter landed in the Ahwahnee Meadow during that alpenglow magic hour about 5:30 pm. The President and First Lady immediately pointed up to Half Dome! From our Every Kid in a Park program, Centennial observations, and our programs to generate the next generation’s interest in the national parks, we are ensuring the next generation of park stewards and diversifying the park. We must instill interest among young people in visiting national parks.
We first hit 4 million visitors in 1996, 20 years ago – and the first year I got to Yosemite. Then our visitations started going down. The Merced River flooded in January 1997, and that had a huge impact on the park. People talked about it as a disaster – but it wasn’t a disaster. While it was a disaster to the infrastructure; a flood is a natural event. It did much good; and gave us the impetus and opportunity to implement many projects. After that Flood of 1997, the park was closed for just 3-1/2 months.
Lodge rooms were washed away. Campgrounds and roads were impacted. The flood allowed us to pause before going ahead. After the flood, annual visitors dropped from 4.1 million to 3.7 million. About 7 or 8 years ago, we were down to 3.3 million visitors. But we’re not trying to increase visitation or get as many people as possible. Our Mission is to preserve and protect the parks and provide good visitor experiences. The usefulness of visitor numbers for us are as barometers—how many people and what type of people are visiting. They also help in our management decisions.
Visitation has dropped to 3.7 from 3.8 million. We were down to about 3.3 million, but then 5 or 6 years ago we started on an upward trend to 3.7 million for many reasons. I tracked these visitation trends very closely. Much of the international visitation that dropped off started coming back. More visitors from Japan, Korea, Germany and England started coming back. We saw more from the emerging markets of China, Brazil, India. Then two years ago we went back to 4.1 million, and last year about 4.2 million.
This year is already a record year. We’re at 4.3 million, and it’s ust September. We estimate 4.8 million for this year, The centennial prompted much excitement, but there are challenges of moving people and getting people in. Every park is different. Zion National Park instituted a shuttle a few years ago to get into the canyon. I went with my family a couple of years ago and think they do a good job,
Each of the 413 National Parks across the country is a bit different. Thus, the shuttle idea at Zion isn’t as conducive here for people coming into and out of the park, since they use the park as a throughway. We always like to say, “Look, Yosemite is not a throughway for going one place to another.” But people do use it as that. For example, people in the San Francisco Bay Area go to Lake Tahoe, via the park on Highway 120. We’re also a big part of the circuit for commercial tours. They come here on crazy 3-day tours from LA to see Yosemite, San Francisco, Monterey, and Napa in 3 days!
On a busy day, we get 60 to 70 tour buses. Many come through; stay here for an hour or two; take a photo; maybe have lunch at the Ahwahnee Hotel; and then leave. A visit may not be long, but since we get many folks here, we have young people controlling traffic control, which can be impeded at Yosemite Falls. Our rangers there direct traffic. Here at Camp 6, the day-use area gets very impacted. Since we get many cars, we suggest people either come early in the morning or late in the afternoon. We figure 6,000 cars come per day – that’s 18,000 people. We start managing it when we get up to 7,000 cars for the day. This year July 3rd was our busiest day, with over 8,000 cars in one day.
We always recommend public transportation. YARTS – the Yosemite Area Regional Transportation System – is great, so we subsidize YARTS. This past year they came up from Fresno, given that almost all the major entrances are served by YARTS. Thus, we are encouraging people to use public transportation – and to avoid the mid part of the day. We’re doing this, but when we’re getting the 6,000, 7,000, 8,000 cars, we’re getting to a point where you just don’t have places to park them.
Our goal is to get people parked, and then onto a bicycle, on a hiking trail, on a shuttle bus, or such. I can remember coming in here as a kid and staying at the Yosemite Lodge cabins. We would drive from Yosemite Lodge over here; park and hang out at Stoneman Meadow, and then drive around. Now it’s our goal to get people to drive in, park, and then take the shuttle bus or walk. To that end, we set up the Merced River Plan to help Yosemite Valley remain protected as precious land.
This is the 100th anniversary of the National Park Service; and last year, 2015, was the 125th anniversary of the Yosemite National Park. The year before was the 150th anniversary of the Yosemite Valley grant, when President Lincoln signed the bill that set it aside to grow as a forest reserve. We like to say this was the birth of the National Park idea – the whole concept of land to be preserved for all time, for all people, where everybody would have access. The Yosemite grant was based here in Yosemite Valley, Mariposa Grove and among the giant Sequoias.
As we go through all this planning, which is part of my job in public affairs, people ask, “Hey, why don’t you build parking garages here, like they do at shopping malls?” And they ask, “Why don’t you have more parking here?” It’s a balancing act. Maybe eventually we’ll eliminate cars, but it’s not our plan right now. But if we’re going to get these vehicles in, we must get them parked and improve the traffic circulation. So, this road construction you see now is implementing the Merced River Plan and increasing traffic flow. Our main day-use parking area, called Camp 6, is closed now. It’s very close to the river, so we’re moving it away from the river to allow some river restoration. It will have a nice restroom instead of a trailer. We’ll puta bus stop there and then build a traffic roundabout to accommodate the thousands of vehicles here at midday. We will also address congestion around Yosemite Falls where you go over the Humpback Bridge as you’re leaving the park. We’ll build a pedestrian underpass where the road goes up, so visitors can walk underneath the road to get to the Falls.
The ice rink, a controversial part of the river plan, is closed. We will have a temporary ice rink this winter here in the parking lot; demolish the concessionary Yosemite Hospitality; and reconfigure that parking lot into an arrival area. Over the next several years, the project will address traffic, parking and circulation issues. The Visitors’ Center is the first thing you look for on arrival, but people driving in go to the day-use parking area have no idea where it is.
There are great river restoration ideas set up in the Merced River Plan. The Merced River is one of the two federally designated Wild and Scenic Rivers in our park, and the other is the Tuolumne River. On this sacred, precious land with so many demands, we have this “Wild and Scenic River” that flows through a valley that’s about 1 mile wide and 7 miles long.
This Yosemite Valley holds the iconic Half Dome, Yosemite Falls and Sentinel Rock, all our campgrounds, lodging, and roads for Curry Village. We had some rock-fault issues, so we removed many of the tent cabins close to the wall’s edge. The Wild and Scenic designation of the Merced River guides our management plan since it needs about a 1/4-mile buffer on either side. We’re moving facilities that were next to the river –the ice rink, locker units and such –
away from the river, even though we have very little land to work with.
I can’t emphasize enough that this precious land is sacred land, and a big part of why Yosemite is here. The old parking lot of Camp 6 was literally right next to the river, so by moving it back we can improve the riparian habitat and the river. We also have crews doing some restoration work above the Ahwahnee Meadow on the way to Mirror Lake. It’s been a great year with so much going on.
I went out to release the pond turtles. You talk about emotion — that was pretty cool! These turtles were raised at the San Francisco Zoo. We reared red-legged frog tadpoles and about 6 pond turtles, releasing them with radio transmitters on them. They looked like the Ninja Turtles. With groups from Nature Bridge and students, we released them into the pond for the first time in over 50 years. They’re all doing well, and we track them. We did the same thing with the red-legged frogs, releasing their tadpoles up in Mirror Lake and in the river. Dr. Roland Knapp, from UC-Santa Barbara, has been bringing many yellow-legged frogs up to of our high-country lakes where we’re restoring them. The Merced River Plan involved 10 years of litigation. It’s now being implemented This is really a very exciting time.
We’ve also introduced the Sierra Nevada bighorn sheep up in the high country. Yosemite Valley is a busy place although it is less than 5% of Yosemite National Park. We estimate 85- 90% of visitors come here, whether they end up here or not. Ahuge demand of people want to come down here. That’s wonderful; but it involves managing vehicles, people, and resources But that management in the last 2 years has been exciting—especially this year. I was there for the Ahwahnee Meadow burn and 8 or 9 years ago we burned the Stoneman Meadow. Jay Johnson, one of the tribal elders came and blessed the burn. They did an amazing job. We had Forest Service crews and crews from Santa Monica. It’s an exciting time.
We’re also doing restoration elsewhere. Mariposa Grove is a huge restoration project down in the grove, being done in partnership with Yosemite Conservancy, a great philanthropic group. They raised over $20 million for this Mariposa Grove project. Another success has been the “un-development” or “de-development project” in the lower grove where there was pavement right up to the giant Sequoia trees. I like to tell people that Yosemite is the bellwether park.
We’re the best of the best. We have Half Dome, the tallest waterfall in North America and all this beauty. But we have challenges with traffic, people, and development. A couple of years ago you’d drive to and amidst the Mariposa Grove of beautiful giant Sequoias. The parking lot was right there. An open-air noisy tram took people through the tree. There was a gift shop and an outhouse toilet -neither befitting of the area. There were impervious hard surfaces, other negative impacts, and only about 100 or so parking spaces.
Visitors had to park at the store and take a shuttlebus 7 miles back and forth to Mariposa Grove, eating into visitors’ available time. On a hot summer day people got cranky. I took a lot of guff. So, we restored the Mariposa Grove with the support of the Yosemite Conservancy. Honoring the incredible groves of sequoias, we removed the tram and put in a new concessionary. The gift shop and all the pavement in the lower grove is gone. The giant Sequoias’ root system is very shallow, and spreads out a long way horizontally. We had paved over all the roots of these giant Sequoias – but now they are uncovered!
Ecologically, by removing the tram road and other infrastructure, the hydrology in the grove has been totally altered. There hadn’t been much new growth of giant Sequoias. They need fire and a lot of water. Putting in old dikes and rows of culverts in rows had disturbed the hydrology. So, we restored Mariposa Grove by getting rid of the gift shop, open-air trams, and rthe pavement in the lower grove!
At the south entrance, the previous area used for logging will now be a parking area and visitors take a shuttle bus for 2 miles to the Mariposa Grove. Once there, it will be a new and better experience. You’ll just shuttle up to a natural, quiet grove with no commercial services and new restrooms and a new handicapped-accessible boardwalk over meadows and water so folks with wheelchairs or mobility-impaired people can enjoy the lower grove.
That’s our biggest project, started 2 years ago. We hoped to get it done this year for the centennial, but heavy snows set us back. It will probably be ready next Memorial Day. It’s a great restoration story. We’ll hopefully get more giant Sequoias to grow back, and next weekend we’ll do a burn. We did one about 10 years ago in the lower grove of the giant Sequoias. Now that it’s closed right, we want to do a real good burn next week.
Next year, Yosemite will be busy. People will say, “Okay, the centennial’s over and the economy is better.” I honestly feel that people will always come to the iconic parks—the Grand Canyon, the Smokeys, Yellowstone, Yosemite. So, it’s our challenge to institute improvements, despite it taking a long time. Now we’re doing many great projects, and have created the Merced River Plan, and new developments on a smarter scale.
There were gas stations, so we had to ask if we really needed a gas station in the park – and decided no. The concessionary that did horse rides created waste from horse urine and feces impacting water flows. Thus, we stopped day rides to meadows above. We’re removing many of the lodge pole pines.
Gregor Schuurman, an ecologist running our Climate Change Response Program, focuses on impacts of climate change as we continue these projects and accommodating our large number of visitors. [See G. Schuurman & J. Meyer Adaptation in US National Parks, 2016]. We plan to restore the land as much as we can; make it as resilient to the people; and accommodate as many visitors as possible while still providing a good experience. After all, the National Park Service wants people to come and have a good experience.
Wilderness use is fairly constant. We see our day use increasing, and tons of folks are on the hiking trails. While wilderness permits have gone very well, over all we don’t see a huge increase..
California visitors are quite tied to California schools, so June, July, and August are still our busiest time. Given our national visitation plus Visit California and nation-wide tourism bureaus, we don’t need more visitors. Everything is sold out. If you’re a hotel owner in Mariposa or nearby, you don’t need to promote the summer. Their efforts are to promote spring, fall and winter. In January and February, European visitors come. We get more American visitors in the off season, but when school is out, there is a surge of visiting families, especially with young kids.
We’re lucky regarding marking or “tagging” on our rocks. We’ve had only a little bit of it. But there’s always a lot of garbage. We just finished our annual cleanup project. Last year we had 15,000 pounds of garbage, but the year before that was 21,000 pounds. The fact that it’s gone down is encouraging sign; but we still pick up 15,000 pounds yearly. I went out with a few fellows and within 45 minutes we picked up 13 pounds of garbage just over behind Yosemite Lodge. We found some of the most random and disgusting stuff.
I think people come to Yosemite Valley just for its beauty,: the granite walls, beautiful waterfalls, rock formations, evidence of the glaciers that came through, and its stunning beauty. People also come to see the wildlife.
One of the best compliments we got was from the White House advance team before the President’s visit. We took them around for a couple of days, including to Sentinel Dome and Mariposa Grove. One White House staffers said to me, “Now this is what a National Park should look like!” Yosemite Falls and the meadows really attract people. I think people come to visit just for the beauty.
Many visitors come in on private tour buses and organized tours. We’ve discussed satellite parking lots outside the Valley or park boundaries so people would come in on shuttlebuses. On one hand, that sounds great, but there are operational concerns. Where will people park? Who’ll operate the buses? Who’ll pay for it?
Right now, we feel that with all that we’re doing now, we can sustain the current level of visitation for the next 5 to 7 years by asking visitors to use YARTS; avoid midday jams by either getting here in early morning or late afternoon; and avoid weekends. If people do those things, that will really help.
What we’re seeing now not a huge amount. According to traffic counters, right now it’s busy, but manageable. The crunch in July and August. Will it get to a point where we’ll have to do something on those months or on those busy days? We don’t know yet, but, again, taking a bus or avoiding the middle part of the day is our short-term solution.
Speeding drivers are an issue. We’ve had 20 bears hit by vehicles this year. Glacier Point Road is a place where bears, people and other wildlife get hit. We’re not seeing road rage, but we are seeing people on Memorial Day or 4th of July just parking their cars and walking in. The folks that direct traffic could tell you stories of having water bottles and expletives thrown at them. I’ve been screamed at a few times, and that is difficult for our young men and women employees who are college students. They’re out there every day and have a very difficult job.
ALISON JONES/NWNL In your great Merced River Restoration Plan, how much focus did you place on water quality and/or flow issues, in both upstream and downstream reaches? And how much did you coordinate with people outside of the park on that river restoration?
SCOTT GEDIMAN We cooperated with the Forest Service. Both the Merced and Tuolomne River headwaters start in Yosemite NP on Mt Lyell (over 8,000’). The Merced River flows out of the park at El Portal into the San Joaquin River and then into the Sacramento-San Joaquin Delta.
The rugged Tuolomne River forms at the Tuolomne Meadows juncture of the Lyell and Dana Forks and flows on through the Grand Canyon of the Tuolomne out of the park and through Modesto. It is then captured by the Hetch Hetchy Reservoir inside Yosemite NP to provide water to the city of San Francisco and Central Valley farmers. When in the Hetch Hetchy and O’Shaughnessy Reservoirs, the Tuolomne’s waters are outside of the Wild and Scenic restrictions since it’s a reservoir.
When the Tuolomne flows through the O’Shaughnessy Dam, it leaves the park. Much of its water goes under or out of the dam which then impacts the river’s riparian habitat. That impacts the humpback whales in the Pacific Ocean and razorback suckers [by preventing nonnative predators to prevent their reproduction.] This caused Bruce Babbit, US Secretary of the Interior to demand testing, oversight and reservoir outflows. The park still does those tests! (Editor’s Note: Babbit served as Interior Secretary from1993-2001 and supported the Endangered Species Act to protect public land conservation).
Our concerns also include water quality, riparian habitat and recreation involves commercial rafts. With the new concession contract, we have lowered the number of rafts that people can take every day, based upon water quality, visual impairments, and the visitor experience. This has been a great benefit from having a concession contract.
We do periodic visitor studies and will hopefully do one next year. Anecdotally, I’ve seen many more African American and Southeast Asian populations. With the Central Valley adjacent to the park, we’ve had great successes with our Every Kid in the Park program. We partnered our education staff with the Merced County schools and brought every one of their 4th graders up here– about 1,200 or 1,300 students. Almost all are from a Latino background and would never have come here on their own. We brought them on buses for the day. The rangers gave them tours and showed them around. It’s a wonderful program! Now we’re seeing many of them bringing their families here on the weekends. We also have a big Southeast Asian population. We’re not yet where we should be or where we’d like to be, but I’m seeing more diversity.
What I appreciate about our centennial celebration, is that it’s critically important not to just end it here. We must really reach out to the next generations. My parents brought us here every year on a vacation, so I’ve known since I was knee-high that I wanted to be a park ranger in Yosemite. I idolized the rangers. That’s all I ever wanted to do. It took me a while, but I got here, and I’m never leaving,
My story and seeing the results of this Every Kid in a Park program, shows the power and brilliance of our campaign to get kids here. I see kids coming from Merced on their first time here. I hear them from where I work over in the administrative building. They come off the bus, yelling and screaming and running around. It’s great to see the smiles on their faces and their parents. It’s a life-changing thing for them. We’ve expanded the program for another year, so I feel we’re reaching out to the young people and diverse audiences. I really feel that now that the President has been here, it’s our responsibility as the National Park Service to reach out. And that is something that we’re really doing and accepting as our responsibility.
