Cause and Effect

 As you read, look for what happens when the number of wolves in the U.S. changes.

Imagine you are a gray wolf in the Montana wilderness. You are one of the most feared predators on Earth. Your razor-sharp teeth can rip through skin and crush bone. You can sniff out a deer from a mile away. Animals many times your size flee in terror when they see you.

You aren’t just any wolf either. You are the alpha of your pack. That means you are the leader. You decide when the pack eats and when the pack travels. You also decide when the pack hunts.

Your kills are as dramatic as a scene in an action movie. You will stalk a group of elk for days and days before choosing one to eat. When you’re ready to strike, you and your pack move together in a deadly dance. You chase the elk until it’s alone and exhausted. And then—you pounce. You and your pack mates clamp on to the elk’s neck and legs with your powerful jaws, until at last the animal collapses.

You and your pack then begin to feast, your faces turning red with blood.

As a wolf, you are what is called an apex predator—an animal at the very top of the food chain. But there is one creature that fills your heart with fear.

Humans.

For hundreds of years, humans in America have hunted, poisoned, and trapped your kind. They have driven you almost to extinction.

And they aren’t finished with you yet.

And they aren’t done yet

It’s a bright, cold winter day, and you and your pack are trotting through the snow. Suddenly, you sense that a human is nearby. Fear washes over you. A member of your own pack was recently shot by a human. You tried to help him, licking his coat and bringing him food. But he did not survive. You are still heartbroken by his loss.

Is a human now coming to kill you too?

  • Wolves use smells to send messages to other wolves. They mark their land with urine and waste—a warning to wolves from other packs to stay away.
  • A wolf’s sense of smell is 100 times more powerful than a human’s.
  • Wolves howl to communicate with one another. They may join in a group howl before a hunt.
  • Two layers of fur keep the wolf dry and warm—even in below-freezing temperatures.

The Big Bad Wolf

The Big Bad Wolf

the 1800s, as many as 2 million wolves lived in America. They roamed the leafy forests of New England. They howled across the deserts of the Southwest. They waded through the icy rivers of the Rocky Mountains.

But to pioneers in America, these fierce and beautiful creatures seemed like cold-hearted killers—monsters even. In the stories the pioneers told their children, wolves were villains, like the one that devoured Little Red Riding Hood’s poor grandmother. Americans’ fear of wolves soon grew into hatred. And as more and more people spread out across the country, wolves began dying out.

Humans shot them with guns. Tricked them into eating poisoned meat. Caught them in sharp metal traps. Turned their fur into fashionable hats and coats.

Then wolves were gone. By the 1920s, in most of America, there were none left.

Flashback to hundreds of years ago. Before the 1800s, as many as 2 million wolves lived in America. They roamed the forests of New England. They howled across the deserts of the Southwest. They waded through the icy rivers of the Rocky Mountains.

Not a Monster

Not a Monster

Fifty years later, many people began to realize that wolves are not the monsters from fairy tales. It is not in their nature to attack humans. Wolves are afraid of humans andavoid them whenever possible.

People began to understand that, in fact, the Earth needs wolves.

As wolves began to disappear, the number of elk exploded in parts of the U.S. That’s because wolf packs weren’t there to hunt them. The elk gobbled up trees and grasses that other animals needed to survive. Birds couldn’t build their nests. Beavers couldn’t build their dams. Without beavers building dams in rivers, the rivers became more powerful and deep. This changed the types of plants that could grow nearby. And meat-eating animals like coyotes and ravens lost a food source: They could no longer pick at the scraps that wolves left behind after a hunt.

Scientists have a special name for animals like wolves: keystone species. Like sharks and lions, wolves are a necessary part of the habitats where they live. Without them, ecosystems change dramatically.

Many people began to say that killing off wolves had been a terrible mistake. The U.S. government passed a law that protected them from being hunted. And then, in the 1990s, wildlife experts hatched a bold plan.

Wolf Territory

A wolf pack’s territory is the area where it lives, hunts, and raises its pups. Packs protect their territory from other wolves. In Canada and Alaska, gray wolf territories can be more than 10 times as big as they are in the lower 48 states of the U.S. 

Once Again Howling

Once Again Howling

The wildlife experts caught 31 gray wolves up in Canada. These wolves were brought down and set free in and around Yellowstone National Park—2.2 million acres of wilderness in Montana, Wyoming, and Idaho. Scientists hoped that these wolves would have pups and form new packs.

To the joy of those scientists, that is exactly what happened. In less than two decades, there were 1,600 wolves in the Yellowstone area. Today, the government says wolves are no longer endangered there.

Many people are thrilled to hear wolves once again howling in America. Thousands of tourists flock to see them in Yellowstone National Park every year. The wolves have dazzled and inspired new generations of wolf lovers. And they are helping to fix the ecosystem in Yellowstone too: Elk populations are now much smaller and healthier.

And the ecosystem in Yellowstone is doing better too. Because of the wolves, elk populations are now much smaller and healthier.

Most experts agree that there are two species of wolf in North America: the red wolf and the gray wolf. In the lower 48 states, some wolf populations are considered threatened or endangered. But in Alaska, wolves have never been endangered. Today, as many as 11,200 wolves live there.

A Fierce Debate

A Fierce Debate

But not everyone is happy about the return of wolves. Some hunters complain that wolves catch and kill the same animals they do. Some farmers are angry because wolves also prey on their cows. (After all, farm animals are far easier for wolves to hunt than wild elk.) Some people say that there are too many wolves now—that they wander off parklands and into places where humans live. A few states have allowed people to once again hunt wolves outside of national parks.

Others argue that wolves should be protected, even in places where their numbers are high. They say that hunting these creatures shouldn’t be allowed.

Indeed, teams of experts are working hard to make sure that wolves do not disappear again. They are raising wolves in conservation centers, planning to release more of them back into the wild. These conservation centers also lead programs to teach people how special and necessary wolves are.

Radio Collars

Scientists put radio collars like this one on wolves so they can track and study them. When trying to put a collar on a wolf, scientists are careful not to chase it in a helicopter for too long. If they can’t catch the wolf within a few minutes, they leave and try another day. That way, the wolf won’t become too stressed or exhausted.

Which brings us back to you on that winter day when you sense a human nearby.

You do not know what is about to happen. But you have a feeling that you are in terrible danger.

Suddenly, a noise thunders from the sky. The noise comes from a helicopter, but you don’t know what a helicopter is.

You break into a full-speed run, zigzagging across the snow. But you aren’t fast enough to outrun the flying metal monster that is chasing you.

Minutes pass.

Your muscles ache. You grow tired. But you don’t stop running.

The helicopter swoops low. There is a man perched inside, and he has something aimed at you.

And then—

Click.

Your body collapses.

Everything goes dark.

You are not dead.

This human did not come to kill you. He came to help you. It was not a bullet that hit you. It was a dart full of a calming drug that has put you into a deep sleep.

The helicopter lands nearby. A man hops out and rushes to your side. He is a wildlife expert who has dedicated his life to studying and caring for your species. He and his highly trained team set up their equipment in the snow. They take your blood to study and test for diseases. They weigh you, check your teeth, and measure your paws. They record notes in their journals.

They work quickly; they must finish before you wake up.

Finally, they put a collar around your neck that has a special radio inside. This radio collar will help them track your movements and learn more about your habits and behavior. Everything they learn will help them better understand you and your kind.

Of course, you don’t know any of this. You are still fast asleep.

When you wake up, the human who had been chasing you seems to be gone. So too is that terrible noise.

You stand, snow covering your muzzle. You lift your head high and let out a long howl.

In the distance, your pack howls back to you.

They are waiting for you to come home.

More About the Story

Skills

Cause and effect, vocabulary, author’s craft, key details, delineating arguments, interpreting text, drawing conclusions, text features, narrative and explanatory writing

Complexity Factors

Purpose

This article traces the history of wolves in America from the early 1800s to present day, explaining how they nearly became extinct then made a comeback.

Structure

The text structure may be challenging for some readers. The first and last sections are told from a wolf's point of view in the present day, while the middle sections are chronological informational passages.

Language

The first and last sections use an unusual second-person point of view, addressing the reader as the wolf in the story. The article contains a good deal of domain-specific vocabulary about wolves and conservation.

Knowledge Demands 

Some knowledge of American geography will be helpful. The article includes references to the Rocky Mountains, Yellowstone National Park, and several states, as well as American pioneers, and Little Red Riding Hood. 

Step-by-Step Lesson Plan

1. Preparing to Read

Preview Text Features and Vocabulary; Watch a Video (40 minutes, activity sheets online)

  • Invite students to make a prediction: Is the number of wolves in the U.S. going up or down? Students should then look at the article’s headline, subhead, section headers, photos, and captions. Do they think the article confirms or refutes their predictions? 
  • Ask a student to read aloud the Up Close box on page 4. 
  • This article contains numerous domain-specific terms related to wildlife and ecosystems. Project the vocabulary slideshow to preview words. Follow up with the vocabulary activity. Highlighted terms: predators, pack, stalk, apex predator, extinction, keystone species, habitats, ecosystems, endangered, prey, conservation, species

2. Close Reading

Read and Unpack the Text (45 minutes, activity sheet online)

Read the article as a class or play the audio version at Storyworks Online. Have students read it a second time in small groups, answering the close-reading questions. Regroup to discuss the critical-thinking questions.

Close-Reading Questions

  • In the first section, author Kristin Lewis writes as if you are a gray wolf and she’s describing your life. Why do you think she does this? (author’s craft) Lewis probably wants readers to relate to wolves by imagining what it would be like to be one. By taking on the wolf’s point of view, readers can more easily understand the wolf’s power and fear.
  • What details do you learn about wolves in the first section? (key details) You learn how wolves hunt, using their powerful teeth, jaws, and sense of smell; that wolves live in packs and are at the top of the food chain; and that humans have hunted wolves almost to extinction.
  • According to “The Big, Bad Wolf,” how did pioneers in America feel about wolves? What happened as a result? (cause and effect) Pioneers were scared of wolves, thinking of them as killers. As a result, they killed as many wolves as they could, with guns, traps, and poison. Wolves disappeared in most of America.
  • Reread “Not a Monster.” In what way had people’s ideas about wolves been wrong? (key detail) Wolves do not aim to kill humans. In fact, they try to stay away from people.
  • How did the disappearance of wolves affect elk? How did that, in turn, affect other animals and plants? (cause and effect) The number of elk increased greatly without wolves hunting them. The elk then ate so much of the grass and trees that other animals, like birds and beavers, couldn’t get what they needed to survive. When beavers didn’t build dams, the types of plants that could grow near rivers changed.
  • In “Once Again Howling,” why did scientists set 31 wolves free in Yellowstone National Park? (cause and effect) The scientists realized that killing so many wolves had been a mistake and wanted to restore balance to the ecosystem. They were hoping the wolf population in Yellowstone would grow—and it did!
  • Reread “A Fierce Debate.” What are the two sides of the debate? (delineating arguments) Today, some people think there are too many wolves; the wolves kill farm animals and target the same prey as hunters. Others believe America’s wolves should be protected so they don’t start to disappear again.
  • The last section returns to the wolf’s point of view. How is the human in this section different from what the wolf expects? (interpreting text) The wolf thinks the human is chasing it to try to kill it. Instead, the human wants to help the wolf by putting a radio collar on it so scientists can learn more about wolves and how to help them.

Critical-Thinking Questions

  • Based on this article, what do you think people need to consider before taking action to change how or where a kind of animal lives—or even whether it lives? (drawing conclusions) Answers will vary, but students might suggest that people should consider how much they know about the animal and whether what they believe about it is true. Perhaps more research is necessary. Students will probably suggest that people should consider how a change to one kind of animal would affect the other animals and plants in its ecosystem. Making one change can lead to other, unexpected changes.
  • Why do you think the first and last sections of the article are in italics? (text features) They are in italics because they are told from a different point of view. They ask you to understand the wolf’s situation as though you were a wolf. Also, the last section picks up where the first section left off. Having them both in italics helps you understand that they are connected.

3. Skill Building

Featured Skill: Cause and Effect

  • Distribute the cause and effect activity, and have students complete it in groups. Then ask them to respond to the writing prompt at the bottom of page 9.

  • Make a Connection Go to the paired texts “The Amazing History of Dogs” from the September 2017 issue. The first article is “How the Wolf Became the Dog.” Project the article and read it together as a class. Invite students to discuss how dogs and wolves are similar and are different, using details from both articles. 

Differentiate and Customize
For Struggling Readers

In a small group, read aloud the first section of the article followed immediately by the last, to help students connect the two. Look at the article together and point out what you just read. Explain that the sections in between will discuss what happened to wolves in general, not just one wolf.

For Advanced Readers

Have students reread the section “A Fierce Debate.” Ask them to do research on each side, then hold a debate on whether wolves should be protected even where their numbers are high. You might assign roles such as farmer, scientist, etc.

For ELL Students

This article mentions many places in the United States that newcomers might not be familiar with, such as Montana, New England, the Rocky Mountains, Wyoming, and Idaho. Help students locate these places on a large map.

For Partner Reading

Pair stronger and weaker readers to take turns reading sections of the article aloud to each other. Encourage them to pause to discuss any words or sentences they don’t understand, as well as parts they find interesting.

Text-to-Speech
