Cast your vote. Rewild Britain! is the country’s latest reality TV show – and we need you to take part. Each contestant is extinct in Britain and all are competing for your vote to get reintroduced back into our forests. Their aim? To help restore ecosystems back to their former glory. You’ll hear pleas from the animals themselves and read each one’s bio before making your final decision. The contestants

28. Bison Interdependence: Act SS2 © Mastery Science, 2022 Last seen in the UK: 6 000 years ago Reason for extinction: Hunting and changes to habitat. How they affect their surroundings: Bison kill trees by rubbing their bodies on them and eating their bark. Removing trees allows other plants to grow, which forms pockets of grassland within large forests. Grasslands can support organisms that forests can’t. Also, the dead parts of the trees that drop to the floor are food for insects and fungi. Feeding: They are herbivores. They mainly eat grass but also feed on tree leaves, bark and acorns. Because of their large size they have to eat a lot! Bison move around in large herds so they spread their waste over a large area. It contains nutrients that helps plants to grow. However, this means they need a very large area to roam, and they can cause problems if they wonder onto roads. Watch bison being reintroduced to Romania bit.ly/3pvO5ed My ancestors roamed ancient Britain a long time ago. I almost became extinct in Europe but have been successfully reintroduced in countries such as Poland and Germany. They’re nice but I would love to live in Britain – I’ve heard the weather is amazing. I’m proud to be Europe’s heaviest living animal – I can weigh a massive 1000 kg but, despite my size, I’m calm and friendly. I wouldn’t hurt a fly – literally – I’m a herbivore so you have nothing to fear from me. I can’t say the some for the other contestants though... What will I do for you? Well, for one I can help you keep the numbers of trees down. This might not sound like a good thing but it will help restore areas of natural grassland. This habitat is home to loads of different plants and animals. So, vote for me to return to Britain and you will be helping other wildlife as well. Vote for Bison!

29. Wolf Interdependence: Act SS3 © Mastery Science, 2022 Vote for Wolf! Last seen in the UK: 1743 Reason for extinction: Habitat destruction and hunting. How they affect their surroundings: Because they eat deer, wolves help to prevent the population of deer in an area from growing too high. Deer are herbivores – they eat plants. If their population grows too high, then there will not be enough plants for other animals to eat. Feeding: They are carnivores. They mainly eat deer but will also eat animals from farms – sheep, goats and pigs. At the moment we have to kill deer every year to keep their numbers down. This is called a cull and they cost money. Wolves will do this for free. Find out about wolves in Germany bit.ly/39zOIxo Are you afraid of the ‘big bad wolf’? Fairy tales teach us that wolves are a danger to humans but this is rarely true. Also, deer destroy forests by eating young trees before they have a chance to grow and replace older trees that have died. I know wolves have a bad reputation as bad guys in your stories. But that's unfair. I've never eaten a grandmother or a small child. I'm ready to forgive and forget if you let us wild again in the forests of Britain. What's in it for you? Well, my favourite meal - deer - are running amok in many forests. They eat all the plants they can find and leave nothing for other poor animals. They're bullies and deserve to be put in their place. I'm the perfect animal to do this. Don't listen to Lynx – by hunting in my pack I can kill many more deer than her working alone. So, if you want Britain's forests to return to their former glory, vote for me! And you like our close relatives - dogs - enough to keep them as pets. Sadly, you hunted my kind to extinction in Britain 200 years ago. Other countries have been more tolerant. Wolf packs still happily roam some of Europe’s forests.

30. Lynx Interdependence: Act SS4 © Mastery Science, 2022 Vote for Lynx! Last seen in the UK: 1300 years ago Reason for extinction: Fur hunting and forest removal Feeding: Lynx are carnivores. They mainly eat small deer but will also prey on foxes, rabbits and birds. Find out about rewilding Lynx in Britain bit.ly/3jdNGdK Some people don’t want lynx reintroduced. Farmers are worried that lynx might kill their sheep and others are worried about possible attacks on humans. How they affect their surroundings: Lynx will help to keep deer numbers low. Currently, deer are overgrazing our forests. Upon the introduction of lynx into forests we can expect to see overgrazing reduced and more trees start to grow. This expands the habitat for our other native wildlife. Also, lynx feed on their prey and then leave the body. This provides food scavengers such as ravens, eagles and pine marten. You may not have heard of me. I'm not a showoff like some others. I'm shy and prefer to keep myself to myself. Many people now want to see me return. There have even been campaigns to help me. You needn't be scared of me. No lynx has ever harmed a person. I never stray from the forest and I only eat wild animals like deer. They're the problem. They eat young trees which can't grow to replace the old ones. Sure, you could hunt the deer, but I could keep their numbers down naturally. I know the wolf will tell you that too. But you can't trust him - he eats sheep, and your farmers won't like that. So, vote for Lynx - it's the only sensible choice. Do you know how my ancestors were wiped out in Britain more than 1000 years ago? Your people cut down the forests and hunted us for our beautiful fur so they could wear it.

31. Bear Interdependence: Act SS5 © Mastery Science, 2022 Vote for Bear! Last seen in the UK: 1500 years ago Reason for extinction: Habitat destruction and hunting. Feeding: Brown bears are omnivorous. They eat a mixed diet of plants, berries, fish, and small mammals. Find out about bears in Italy bit.ly/3tkErND Bears do not hunt people. But, every year in the USA several people are attacked, and sometimes killed by wild bears. Bears also help to clean up the dead bodies (carcasses) of animals and, as predators, they help keep populations such as deer in balance. There haven't been any of us in Britain for a long time- thousands of years. But I think that needs to change. I'm not a fussy eater - I'll eat almost anything. And I can help keep the numbers of many different species under control when there’s too many of them. I'll even eat the carcasses of dead animals and clear all that mess up. I can help plants too - by eating their fruit and nuts and spread their seeds by ...ahem...pooping them out everywhere. OK, I can be a bit scary if you bother me when I'm in a bad mood. Just keep out of my forest and you’ll be fine. So, it makes perfect sense to vote for Bear to return to Britain. How they affect their surroundings: In eating fruit and nuts, bears help disperse seeds, which helps plants to reproduce. It's obvious you're fond of us. I mean you love to cuddle toy bears at night. How marvellous would it be to have the real thing in your forests?

32. Effects on the food web Interdependence: Act SS6 © Mastery Science, 2022 Bison Eats grasses and acorns ( seeds) Lynx Eats foxes and young deer Wolves Eats young and adult deer deer insects bats woodpeckers squirrels finches foxes owls nuts, seeds & fruit leaves grasses What would the effect of rewilding each one be on other organisms in the food web? Explain which animal would have the most positive effects. What to do: Put each animal into the forest food web. Aim: To work out the positive and negative effects of rewilding each animal into Britain’s forests.

33. Aim: Persuade an audience that it should be your animal that gets rewilded. To do that, you're going to create a short, persuasive presentation. You will: make claims for why your animal should be chosen give evidence and reasons to back up your claims A . Collect evidence for the claims There are four claims: 1: Your animal can survive in Britain. Where to collect the information: Evidence sheet 2: People want it to be rewilded. Where to collect the information: Evidence sheet 3: It has a positive effect on the food web. Where to collect the information: The food webs task you just did.

Plan your presentation Like a story, a presentation should have a beginning, a middle and an end. Here's what to include. Beginning Give an overview of what you will talk about Give some information about rewilding to interest the audience. Middle Strongest claim Choose the strongest claim for rewilding your animal  State the claim Give evidence, with reasons to support your claim. Other claims Briefly describe at least two other claims Give evidence and reasoning for each. End Repeat your strongest claim and the best evidence for it Tell your audience what to do - vote for your animal! 4: It has other benefits Use the link for your animal.

34. Bison evidence sheet Interdependence: Act SS8 © Mastery Science, 2022 The bison’s natural habitat is a large forest. But they can survive in any habitat where there is a mix of forest and grassland. Britain has many areas like this. Bison once lived in forests in Britain. By the 1950s they had all gone. The cause was hunting and destruction of their habitat.  In 2007, the Netherlands introduced three bison into a coastal area which was a mix of forest, grassland and sand dunes. The graph shows what happened. Estimated numbers of bison in each country in 2020 European countries have now reintroduced bison into the wild. Their numbers have grown to thousands. 1400 250 100 150 10 20 1900 1400 200 10 40 20 50 100 100 30 The result was surprising. Despite only being given a small area to roam ( 3 km 2 ), the bison managed to survive. Their numbers increased most years. Thousands of people in Britain were asked if they would like bison to be rewilded. The chart shows the % who would, for each age group. Why did bison go extinct in Britain? What have scientists found out about rewilding bison? Does Britain have any suitable habitat? What does the public think?

35. Wolf evidence sheet Interdependence: Act SS9 © Mastery Science, 2022 Why did wolves go extinct in Britain? What have scientists found out about rewilding wolves? Does Britain have any suitable habitat? What does the public think? Many people think that the Scottish Highlands is a good place to rewild wolves. Wolves used to live in forests across Britain. Scientists created a computer simulation to predict what would happen if 12 wolves were rewilded into the Scottish Highlands. The graph shows the predicted numbers of wolf and deer populations for the next 100 years. No European countries have yet reintroduced wolves. But many are considering it. The scientists also questioned people in the Highlands to see how positive they were about the idea. The chart shows their opinions. It’s home to a lot of deer, which are the wolves’ prey. In fact, there are too many deer, which are destroying the plant life. Because of hunting, their numbers gradually decreased. We think the last remaining wolf was killed in 184 3, in the Scottish highlands.

36. Lynx evidence sheet Interdependence: Act SS10 © Mastery Science, 2022 Why did lynx go extinct in Britain? What have scientists found out about rewilding lynx? Does Britain have any suitable habitat? What does the public think? Lynx need woodland where there is plenty of prey - mostly deer. Two factors drove the lynx to extinction in Britain around 1300 years ago. They were hunting and the destruction of woodland. Lynx have been successfully rewilded in several places in Europe including Spain, Portugal, Germany and Croatia. Scientists have been researching suitable places in Britain. They found that Scotland has enough suitable woodland to support a population of 400 lynx. There are also suitable areas of woodland in England where they could live.  These areas are shown on the map. Scientists asked 1000 people from around Britain if they agree that lynx should be rewilded in Britain.  The pie chart shows the results.
