Introductory Note

After a week’s conference in Sacramento CA for the Society of Environmental Journalists, during an unusually severe California drought, a small group 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 exploring this protected wonderland.

CURRENT POPULARITY of NATIONAL PARKS

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 just kind of 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, turtle, 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. Some of you may have noticed the detour signs, closed roads and parking lots closed due to the work that we’re doing.

Regarding the visitation of the park overall, this has been a big year for many reasons, including President Obama’s visit this 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, many urban areas, and commercial ventures, including Disneyland and Universal Studios. I think 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’re seeing a huge amount of visitation in National Parks across the country – including at Grand Canyon National Park, Rocky Mountain National Park, and also parks that have been busy, like Mesa Verde National Park, Arches, Canyonland National Park,  which is absolutely 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 the trails. In fact, the President had never been here, and he just had all these 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 are critical to ensuring the next generation of park stewards and diversifying the park. We must instill interest among young people in visiting national parks.

The FLOOD of 1997 IMPACTS & VISITATION RATES

SCOTT GEDIMAN  We first hit 4 million visitors in 1996, 20 years ago – the first year I got to Yosemite. Then our visitations started going down. The Merced River flooded in January of 1997, which had a huge impact on the park. People talked about it as a disaster – but it wasn’t a disaster. It was a disaster to the infrastructure; but a flood is a natural event, and it did much good. It gave us the impetus and the opportunity to implement many projects. After the Flood of 1997, the park was closed for 3-1/2 months.

Lodge rooms were washed away. Campgrounds and roads were impacted. The flood really gave allowed us to pause before going ahead. After the flood, visitors annual 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. Visit numbers are useful for us as barometers—how many people are visiting and what type of people are visiting—and they also help in our management decisions.

Visitation has dropped to 3.7 to 3.8 million. We had been down to about 3.3 million, and then 5 or 6 years ago we started on the upward trend to 3.7 million for many reasons. I tracked these visitation trends very closely. Much of the international visitation that had dropped off started coming back. We started seeing more visitors from Japan,  Korea and European destinations. Folks from Germany and England started coming back more. We saw more of the emerging markets—China, Brazil, India. Then 2 years ago we went back to 4.1 million again, and last year about 4.2 million.

This year is already a record year. We’re at 4.3 million, and just in September. We estimate 4.8 million for this year, The centennial prompted much excitement. It’s wonderful, 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 the do a good job, 

Each of the 413 National Park units across the country are 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 use it as that. For example, people in the San Francisco Bay Area go to Lake Tahoe, for example, via the park on Highway 120. We’re also a big part of the circuit for many commercial tours. They come here on crazy 3-day tours from LA to see Yosemite, San Francisco, Monterey, and Napa in 3 days! We get many of those. 

On a busy day, we’ll get 60 to 70 tour buses here a day. Many people come through, stay here for an hour or two, take a photo, maybe have lunch at the Ahwahnee Hotel, and then leave. A visitation may not be long, but since we do get many folks here, we have young people doing traffic control, since traffic can be impeded over at Yosemite Falls. Our rangers literally out there directing traffic. Here at the Camp 6 – the day use area gets real impacted. Since we get many cars, we suggest people either come real 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, of course, is to get people parked, and then either on a bicycle, on a hiking trail, on a shuttle bus, or such. It’s interesting that I could remember coming in here as a kid and staying over at the Yosemite Lodge cabins. Our thing as a kid was to get the car from Yosemite Lodge, come over here, park at Stoneman Meadow, hang out, and people would drive around. And we haven’t made it forbidden, but it’s our goal to get people to drive in, park, and then take the shuttle bus or walk, So to that end, we’ve set up the Merced River Plan to help with parking. Clearly, Yosemite Valley must remain protected as precious land.

This is the centennial – the 100th anniversary – of the National Park Service; and last year, 2015, was the 125th anniversary of the Yosemite National Park. and 2014 was the 150th anniversary of the Yosemite Valley grant, whereby on June 30, 1864, 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 like they do at shopping malls?” or “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, a lot of this road construction you’re seeing is implementing the Merced River Plan and increasing the 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 – and we’ll make it more organized with a nice restroom instead of a trailer. We’ll have a bus stop there and then build a traffic roundabout that people driving in—and the whole idea for the roundabout will accommodate thousands of vehicles in our busy midday time. Another change will be to 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, and then visitors can walk underneath the road to get to the Falls.

The ice rink, which was a controversial part of the river plan, is closed. We will bring in a temporary ice rink this winter  right out here in the parking lot. We’ll demolish the concessionary, Yosemite Hospitality, and reconfigure that parking lot, for an arrival area. Over the next several years, the project will address issues of more traffic, parking and circulation. The visitors’ center the first thing you look for on arrival. Now, people driving in get directed to this day-use parking area and have no idea where they are.

The MERCED RIVER in YOSEMITE VALLEY

SCOTT GEDIMAN  There are also 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 on it, we have this Wild and Scenic River that flows through a valley that’s about 1 mile wide and 7 miles long.

This is the Yosemite Valley that holds the iconic Half Dome, Yosemite Falls and Sentinel Rock, as well as all our campgrounds, lodging, and roads for Curry Village. We also had some rock fault issues, which Joe Meyer can talk about, so we removed many of the tent cabins that were very close to the wall’s edge. The Wild and Scenic Merced River basically guides our management plan since we need about a quarter mile buffer on either side. On either side of that are walls where rocks falls continue to happen, so we can’t develop close to that wall.

We’re moving facilities that were next to the river—the ice rink, locking units and such – away from the river, and basically you have very little land to work with, and then—I can’t emphasize this enough—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.

RELEASING TURTLES & BIGHORN SHEEP

SCOTT GEDIMAN  I went out to release the pond turtles. You talk about emotion — that was pretty cool! These turtles were given a head start at the San Francisco Zoo. We reared both red-legged frog tadpoles and about 6 pond turtles and then released the out here with radio transmitters on them. They looked like the Ninja Turtles. With groups from Nature Bridge and some students, we measured them all, and released them into the pond for the first time in over 50 years. They’re all doing well, and we now track them. It was wonderful to see that. 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 was a very long road, but now it’s done and we’re implementing it. It’s really a very exciting time.

We’ve also introduced the Sierra Nevada bighorn sheep up in the high country. No one’s going to deny that Yosemite Valley is a busy place. Yosemite Valley is less than 5% of Yosemite National Park, but we estimate between 85% and 90% of visitors come here, whether they end up here or not. There’s a huge demand of people wanting to come down here. Again, that’s wonderful; but, again, it involves managing vehicles, people, and resources…. But that management in the last 2 years has been exciting—especially this year.  I was out there for the Ahwahnee Meadow burn; and I remember 8 or 9 years ago when 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 was great to do that and now now to do these restoration projects. It’s an exciting time.

Grazing bighorn sheep have been introduced in the high country.

MARIPOSA GROVE RESTORATION

SCOTT GEDIMAN  We’re also doing a lot of these restoration projects elsewhere. Mariposa Grove is a wonderful project. It’s a huge restoration project down in the grove, being done in partnership with Yosemite Conservancy. I was just there a couple of weeks ago – the day before the centennial, with some folks from the 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’s been pavement right up to the giant Sequoia trees. I always like to tell people that Yosemite is the bellwether park – which is what B.J. Griffin, the superintendent when I arrived here over 20 years ago, used to say.

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. Yet it’s exciting, and a challenge. Mariposa Grove is a good example of that, A couple of years ago you’d drive to the Mariposa Grove, with its beautiful giant Sequoias. You would literally drive in amidst the giant Sequoias. The parking lot was right there. An open-air noisy tram would take people through the tree. There was a gift shop, and an outhouse toilet that wasn’t 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 then take a shuttlebus 7 miles back and forth to Mariposa Grove, which ate into visitors’ available time. On a hot summer day people would get cranky. I took a lot of guff. So, we said, okay, here’s our chance to restore the Mariposa Grove with the support of the Yosemite Conservancy. We have the incredible upper and the lower groves of gorgeous sequoias, so we decided to remove the tram, and put in a new concessionary. The gift shop is demolished, as is all the pavement in the lower grove. The giant Sequoias’ root system is very shallow, and they spread out a long way horizontally. Basically, we had paved over all the roots of these giant Sequoias. They are now uncovered! 

It is ecologically fascinating that by removing the tram road and other old infrastructure, the hydrology in the grove has been totally altered. We didn’t have much new growth of giant Sequoias. They need fire, of course and a lot of water. But putting in old dikes and rows of culverts in rows had disturbed the hydrology. So, we decided to restore the Mariposa Grove – get rid of the gift shop, stop using open-air trams, and remove the pavement in the lower grove!  

At the south entrance, we had a previously disturbed area used for logging. Now, that will be a parking area and one can take a shuttle bus for just 2 miles to the Mariposa Grove. Once there, it will be a new experience. Instead of having no place to park and hearing the tram and gift shop clatter, you’ll just shuttle up to a natural, quiet grove with no commercial services and new restrooms. Another improvement to the site’s hydrology is a new boardwalk access over meadows and water in the lower grove. It’s handicapped-accessible, so folks with wheelchairs or mobility-impaired people can enjoy the lower grove. 

That’s our biggest project, started 2 years ago with the sesquicentennial, the 150-year. We were hoping to get it done this year for the centennial, but heavy snows set us back. It will probably be ready about next Memorial Day. It’s a great restoration story, and interesting, because people ask, “Well, are the giant Sequoias at risk?” It’s not so much that they’re at risk, but we hope removing the pavement will provide more growing. We’ll hopefully get more giant Sequoias to grow back, and next weekend 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. With our new shuttlebuses, we can accommodate 1,000 to 2,000 people a day there. 

Next year, Yosemite’s going to be busy, People will say, “Okay, the centennial’s over and the economy is better.” That will be true, but 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. We had to get the Merced River Plan going, despite it taking a long time. And now it’s done, 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, will talk to you about impacts of climate change as we continue these projects and accommodating our large number of visitors. 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 PERMITS & GARBAGE

FEMALE JOURNALIST  Have you seen increases in wilderness permits?

SCOTT GEDIMAN  Wilderness use is about the same despite ongoing fills and unfinished projects. We see our day use increasing, so there are tons of folks on the hiking trails. Wilderness permits have gone very well, but over all we’re not seeing a huge increase.

MALE JOURNALIST  Quick one about visitation: is your visitation season starting earlier and/or persisting later into the year?

SCOTT GEDIMAN That’s a good question. Regarding California visitors, they’re quite tied to California schools, so June, July, and August are still our busiest time. But given our national visitation, and working with 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 somewhere else nearby, you don’t need to promote the summer. Their efforts are to promote the spring, fall and winter, but it’s interesting, that in January and February, European visitors are coming. We’re getting more American visitors in the off season, but we’re fooling ourselves if we don’t think that when school is out, there will be a surge of visiting families, especially with young kids. We have been lucky with 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 facelift –our annual cleanup project. Last year we had 15,000 pounds of garbage, which is a lot, but the year before that was 21,000 pounds. The fact that it’s gone down is an encouraging sign that people are littering less; 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.

THE VALUE of a YOSEMITE VISIT

FEMALE JOURNALIST  There are two brochures that people get when they arrive here.  But in your words, why should someone come here?  What can you see? hy is it interesting?  I have my own answers, but I’m interested in yours.

SCOTT GEDIMAN  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 from the White House advance team before the President’s visit. We took them around for a couple of days, including 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.

EVEN FURTHER EXPANSION…?

SCOTT GEDIMAN  Many visitors come in on private tour buses and organized tours. We have YARTS, so we’d like to see YARTS expand. 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, including: 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 5-7 years by asking visitors to use YARTS; avoid midday jams by either getting here in early morning or late afternoon; and avoiding weekends. If people do those kinds of things, that will really help.

But as far as the long term, again, we don’t know. 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.

However, 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. And 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 a difficult situation for our young men and women employees who are college students. People say I have a tough job. They’re out there every day and have a very difficult job.

MERCED & TUOLOMNE RIVER OVERSIGHT

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 River and Tuolomne River headwaters start in Yosemite NP on Mt Lyell (at over 8,000’). The Merced River then flows out of the park at El Portal into the San Joaquin River and then into the Sacramento-San Joaquin Delta. The oversight of the Merced River, as it leaves the park, is then under Forest Service and BLM, and we coordinate with them. 

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.

As 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 compacts the river’s riparian habitat and that impacts the humpback whales 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. Having a new concessioner coming in is good, because we could first determine if gas stations should be closed, and other restrictions.

PARK ATTENDENCE OUTREACH

SCOTT GEDIMAN  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.

YOSEMITE’S IMPACTS on YOUTH

SCOTT GEDIMAN  What I appreciate about our centennial celebration and mentioned to folks in Washington, is that it’s critically important not to just end it here. We must really reach out to the next generations I always like to say, my parents brought us here every year on a vacation. 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 these kids here.  I see kids are coming from Merced on their first time here. I hear them from where I work over in the administrative building… you know how kids are!

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.

WOMAN JOURNALIST  Thank you so much, Scott, for helping us get here.
