Power line threatens bighorn sheep

Report cites possible lost habitat in Anza-Borrego | Saturday, January 12, 2008 8:31 PM PST

A Peninsular bighorn sheep ram in Borrego Palm Canyon, Anza-Borrego Desert State Park, in October. A recent report said the proposed Sunrise Powerlink would threaten the endangered species' survival in the park and throughout the West, because the wary animals would abandon critical habitat and watering holes.

If San Diego Gas & Electric Co.'s proposed Sunrise Powerlink transmission line winds up going through Anza-Borrego Desert State Park, a recent report says, it may scare away the animal that graces the park's logo: The Peninsular bighorn sheep.

And there may be no way around that.

An environmental-impact report prepared by state and federal agencies concluded that the project would disturb 88 acres of bighorn habitat, and suitable replacement habitat may not be available nearby to make up for it.

Even if suitable lands can be found, the report said, the noisy helicopters used in the construction of transmission towers, the presence of new access roads to the towers and the constant crackling and buzzing of 500-kilovolt wires could persuade the bighorn to permanently leave the area where the power line would come through.

"If you ask me ... it is not worth the risk," said Mark Jorgensen, Anza-Borrego park superintendent.

The report released Jan. 3 was prepared by the California Public Utilities Commission and the U.S. Bureau of Land Management, agencies that must give permission before SDG&E can build the $1.3 billion project.

A decision is expected by late summer.

SDG&E provides electricity to virtually all of San Diego County and the southern one-third of Orange County.

The utility's new line would deliver 1,000 megawatts, boosting the region's electricity supply by about 20 percent. During cool times of the year, that is enough electricity to keep the lights on in about 750,000 homes, but much more is required to power air conditioners during summer heat waves.

SDG&E essentially wants to build a 150-mile superhighway of electricity between El Centro and Carmel Valley.

The project would have 91 miles of 500-kilovolt wires and 59 miles of 230-kilovolt wires. A kilovolt is 1,000 volts.

The utility's preferred route would wind through Ranchita, Santa Ysabel, Ramona and Rancho Penasquitos, and nearly 25 miles of Anza-Borrego park.

At 600,000 acres, Anza-Borrego is the largest state park in the United States outside Alaska. It is famous for its clear, unobstructed, panoramic views, as well as several oases of native fan palms.

The park also is known for being a refuge for the endangered desert population of the bighorn sheep, which lives in the so-called Peninsular mountain ranges that extend from Palm Springs to the U.S.-Mexico border. Indeed, the park is even partly named after the bighorn sheep: Borrego is the Spanish word for the animal.

Still, a visitor is more likely to see the bighorn's mug on a photo or park sign than to see one of the animals roaming the rugged Anza-Borrego backcountry.

"They're incredibly elusive," said Ernie Cowan, outdoor editor for the North County Times, who has extensively photographed the animal. "They are masters of blending in with their environment. But when you do see them they are majestic ... they are magnificent animals."

Cowan, who is set to publish this week a book on Anza-Borrego, said the wild sheep are skilled at living in a beautiful but hostile hot and dry environment.

"Their ability to scramble up a practically vertical mountainside in moments is astounding," he said. "They move with seemingly effortless speed up the side of a mountain."

As skilled as they are at living in their natural environment, however, they aren't very good at living around humans and the things they build.

As the 7,000-page environmental report put it, the bighorn is a true wilderness animal.

And, so, rather than adapt to towering metal poles up to 160 feet high, the 40 to 50 bighorns that live in the Grapevine Canyon area of the park might well move on - and put pressure on bighorn groups elsewhere - if high-voltage wires are strung through it, the report says.

There also is a chance the animal could view the power line as an obstacle to avoid at all costs and refuse to travel back and forth under it, the report states.

"If that line goes through, it will divide the northern and southern herd, which could be very detrimental for their breeding," said Diana Lindsay, vice president of environmental affairs for the Anza-Borrego Foundation and Institute. The line "would intrude into an area where they can freely roam."

But, the report says, it is difficult to state with any certainty how the bighorn would react.

So much is unknown, said Jorgensen, the park superintendent. "Nobody knows what a bighorn sees or what it hears," he said.

What the region's leaders do know, however, is that the high-voltage line would be a huge presence. Its steel poles would be three times higher than the wooden ones there now, he said.

And they would carry wires much bigger - and much louder - than the quiet 69-kilovolt line that has crossed the park for decades.

"The 500-kilovolt line has so much juice going through it that it actually makes noise and sparks," Jorgensen said. "There is a sparkling and crackling going on on this thing all the time."

Jorgensen said it is also known that the bighorn is on a precarious perch in its bid for survival, at a time when its home is increasingly being encroached upon by human activity.

"You're talking about a remnant population. You're talking about greatly reduced habitat, not only in California but all over the West," he said. "And you're talking about throwing more threats at that population."

Before the Gold Rush, there were as many as 2 million bighorn sheep spread throughout the Western states, and today there are only about 40,000, Jorgensen said.

The Peninsular bighorn represents a tiny fraction of that total. According to the environmental report, the population has rebounded to about 700 in the Southern California desert, and as many as 450 of them live in Anza-Borrego park.

The 700 figure represents a significant rebound from the total of 280 that were counted in 1995, Jorgensen said. But it is still well below the 1,200 total from three decades ago, he said.

"We're on a good upward trend," Jorgensen said. "But their future is not secured yet and there is no shortage of proposals on how to encroach on their habitat."

Senior wrote on Jan 12, 2008 10:05 PM:This is a sad time in our country. Objection is made to building a needed power line that can light up 750,000 homes because 40 or 50 bighorn sheep live on 88 acres where the line would come through in the 600,000-acre Anza-Borrego State Park. But wait, there is more in the article. These sheep live in the mountain range that extends from Palm Springs to the Mexican Border. The article says there are 450 of them in the park, and 300 more nearby outside the park. Nobody knows whether the sheep will care if the power line is built there. Maybe they will want to move on. If those 88 acres is so special to them, maybe the power line could be routed around it. The article says maybe they won’t want to move under the power line to go breed with the northern or the southern herds like they do now. Fat chance of that! I have seen when cows on farms want to breed the bulls will crash through farm fences to get to them. It’s unlikely the sheep would stop for wires 150 feet above them when it is time to breed.

This is just another typical liberal enviro-pagan attempt to distort facts and nature. The Animals don't care. The end result, as usual, is higher costs for humans.

This is all nonsense wrote on Jan 13, 2008 7:12 AM:In all my trips to Borrego I have seen the sheep twice. It is rare to see them as they hide in the hills. These sheep are tough, a lot tougher than the weak human Chicken Little types that want to impede progress.

Don't harm the Bighorn wrote on Jan 13, 2008 7:43 AM:The sheep are not that elusive. I was camping in the main campground a few years back and when I awoke in the morning there were several bighorns near the base of the hill in back of me. It was really cool. We should protect these incredible animals.

Jacque wrote on Jan 13, 2008 7:56 AM: If you ask me, it is worth the risk. We don't live in a perfect world, we just need to weigh the pros and cons. In this case, we are taking about a transmisson line that would boost our regions electricity supply by 20%. This comes at a time when our state government was recently contemplating requiring a receiver in all new homes that wold allow the state to regulate the temperature setting and the electricity usage in our homes! Come on people, lets look at the big picture here! We need this transmission line!!

can't wait for this summer wrote on Jan 13, 2008 8:17 AM:I want to see what BLM decides. If they allow this to happen then they will have to also open up all the closed areas in Glamis. At least we have actual reports showing we are not hurting the anything. There has been proven facts that power lines do indeed hurt humans and cause birth defects and cause a type of cancer (I don't remember what type though). I know when I am 4 x 4ing out in burrego I don't want to hear the buzzing of high power lines! Too bad things are coming down to this. and too bad that california has such strict construction laws that it is almost impossible to build any power plants here! God help us all.

Debrah wrote on Jan 13, 2008 8:29 AM:Right on !, BOB
We need to stop this mindset that we are entitled to every square inch of land, just to fulfill our human "needs". There has to be genuine attempts by these utility companies to utilize our renewable natural resources,ie. wind, solar, hydro. I want to find out more on how we can lobby our politicians (State, Local) to step up and start demanding and not caving into these bloated utilities.
As far as I recall the Pennisular Bighorn are an extremely endangered species. We all need to become stewards of our planet Earth. I so much want to see one of these beautiful creatures in its own element and hope I can one day and hope they are there for my young daughter to see when she becomes able to enjoy the beauty of our Earth.

Unbelievable wrote on Jan 13, 2008 8:41 AM:It's sad how much ignorance there is out there. People making comparisons between cows and Bighorn Sheep to justify this idiotic plan to provide power to an overpopulated SD County. I am no tree hugger but how about some common sense people. Would you also string power lines through Yosemite Valley or over the Grand Canyon in the name of progress? How about we build a power plant or two locally and not be at the mercy of energy brokers as we were a few years ago (REMEMBER ENRON?) The money that was stolen from the coffers of this state could have built a number of locally controlled power plants. But that is all history with obviously no lessons learned. Hey, how about this idea, why don't they string the power lines along Interstate 8 into SD? I'm sure the presence of power lines won't keep gamblers away from East County casinos! Let's see if NCT posts this one, they didn't last time....out

Shareholders Threaten Big Horn Sheep wrote on Jan 13, 2008 8:42 AM:It is all about money. You "sheep" who buy the corporate line about the dire need of this power line are just big suckers. Same as the people who bought into the airport emergency. It is all about empire building. The powers that be would make millions off a multi billion dollar new airport. THe public be damned. Put a stop to these grandiose projects now.

Give me a break wrote on Jan 13, 2008 8:43 AM:What a bunch of BS! I suppose the campers, bikers and shooters help the species. If you want to keep buying middle east oil oppose this your helping them fund your end. There will be more room for sheep if a good Nuke goes off. This is where we will get new solar power from. Get a clue!!!! The sheep don't care!

Warner: wrote on Jan 13, 2008 10:18 AM: I read a lot of maybes in the above article. who is trying to stir something up? Are the goats an endangered species? Perhaps the crackling and buzzing would make them want to breed? I do know that goats are very adaptive; i.e., they can adapt to just about any change in environment. The goats of San Clemente island even adapt to living in a USN bombing zone. Are the goats indigenous to the area? Are there other endangered species in the park that the goats are harming; or is it that they just look good there? I suggest you get all your for certain data together and come back with a report. Meanwhile continue with building the power line. Your current data is about as good as a hill of beans.

Bo wrote on Jan 13, 2008 11:23 AM:Why can't they follow exisisting roadways for the power line? That certaintly makes more sense than ruining the beauty of Anza Borrego State Park!

Hates SDG&E wrote on Jan 13, 2008 3:55 PM:Bo

The answer to your question is because SDG&E and SEMPRA energy have other motives than just putting in a line. Like PROFITS, oh and yes they have NO common sense !!

JSten wrote on Jan 13, 2008 4:09 PM:AWWWWW! Dont kid a kidder! People have been buzzing the sheep for years whether in planes, choppers, or on bikes. The sheep will do what they do, move and stop and look, move and stop and look. Once they realize that the noise isn't about them they will tune it out.

... You would think that our sheep and goats are somewhat more fragile than their cousins all over the west.Do the[y] actually think that the sheep are that fragile?

3rd Generation San Diegan wrote on Jan 13, 2008 4:13 PM:I've lived in this area more than 50 years. So much open space has been paved over, electrified or occupied by suburbia during that time. My brothers and I used to be able to ride our bikes to streams (to collect frogs and crayfish) and open fields. It's all gone, covered by homes or in a drainage pipe.

I don't argue the need for more power here in San Diego. Even if the population were kept static, we'd need more power because of our increased dependence on electronic entertainment and computerization. Build a linkage between San Diego and the suppliers to the East, but don't do it at the expense of one of the few last open spaces in San Diego County. I've had colleagues come from Sweden, the UK and China for technical meetings who've asked me to take them out to Borrego. Our desert is known around the world, yet we (and SDGE) don't seem to appreciate it here. Underground the wires, build the power lines along existing roads or use existing pathways for electrical power. Who knows about the sheep (I've only been lucky enough to see them twice); what about our own kids?

Citizen wrote on Jan 13, 2008 4:24 PM:The Borrego Goats are fairly hardy. I once saw one fall off the side of a cliff and onto the road in front of me. It was a little stunned, like it was thinking - "How could I be so stupid?" But got up and climbed back up the cliff.

SDG&E should help folks in the sunniest areas of the county install solar panels and pay homeowners for the electric they produce instead of paying for the electric from their dirty, polluting plant in Mexico. (all that pollution just blows back across the border into the US.)

If they need more power than solar on American rooftops can provide, build or vastly expand nuclear plants in and around San Diego.

For alarmist, More people die from the pollution of coal and gas power plants Every year, than all 60 years of nuclear power plants.

Jason L wrote on Jan 13, 2008 5:50 PM:Simple fix: Power lines should parallel the roads.

Let's confine our avenues of ugliness, excess, and waste to these existing corridors.

Daren wrote on Jan 13, 2008 8:34 PM:The extra power is necessary. There's no getting around that concept. However, is there a reason why the power lines could not be built underground. That would preserve the aesthetic value of the region, eliminate the fire risk and provide the power we need. I have not read the EIR or SDG&E's proposed plan, since I live so far from the affected area.

Roberto1 wrote on Jan 13, 2008 9:09 PM:Theses right-of-ways are worth millions...What is amazining to is this belief that we must allow this desicration and blight of our national forest. Build a power plant in San Diego...it only makes sense to stop importing power from Mexico, Canada, Texas when we can do it ourselves..the redundant infrastructure of back is already in place and only need to be enhanced through existing corridors.

Give me a break wrote on Jan 13, 2008 9:36 PM:I'm for prtectig the environment, but these environmentalist are really using these sheep as a lame excuse much like those who opposedthe Alaskan pipeline and the caribou.

All you have to do is see the towers as wonderful, bringing the wonders of modern heat, light, air conditioning, and employment opportunities for hundreds of thousands of persons in industry, warehousing, retail and other business.

Senior wrote on Jan 14, 2008 4:10 PM:TOall posters above who suggested along highway 8, consider this.
At some furture time there will likely be earthquakes, terrorist attacks on power lines, plane crashes, etc. You should not carry all your eggs in one basket, nor put all your powerlines in one corridor. It is simply not wise.

Austin wrote on Jan 17, 2008 9:47 AM:We have no proof the sheep will avoid going under power lines; also no proof that they will. It is folly to put a herd at risk "because they can just go elsewhere" -- A few more projects like this and there will be no more "elsewheres" The sister project-- "Green Path North" carves a line right through the habitat of 1/3 of Joshua Tree National Park's herds and cuts them off fromthe only guaranteed water. We need the power? Generate it locally. Less destrruction, LESS vulnerable to attack, easier to access if downed (= less big fires)...

He, and people like him... need to lighten up. Oh by the way, the only way the public can get into their clique, is to either volunteer into their indoctrination, or buy a book.
