The Sonoran Desert National Monument, a biodiverse haven for endangered species, is severely damaged by target shooting. Despite the Bureau of Land Management's own findings of harm to wildlife, Indigenous sites, and human health, 90% of this precious area is now littered with toxic lead ammo and makeshift targets, destroying ancient saguaros and petroglyphs. The Center for Biological Diversity works to protect such vital lands and species from extinction.

Jeff Corwin joins conservationists in California to protect pinnipeds, including elephant seals and sea lions. Organizations like the Marine Mammal Care Center and Defenders of Wildlife are crucial in rescuing and rehabilitating these animals, which face severe threats from climate change, overfishing, habitat loss, and plastic pollution.

Corwin assists Dr. Lauren Palmer and Andy Johnson in rehabilitating four malnourished California sea lion pups, one of whom ingested plastic. After critical care, tagging, and weighing, the pups are successfully released back into the wild. This effort underscores the vital role of conservation in giving endangered animals a second chance and addressing environmental challenges for ecosystem health.

Join host Jeff Corwin as he connects with a collection of amazing mammals that face difficult conservation challenges. First, Jeff travels into the remote forests of New England to help care for a rowdy group of orphaned baby black bears. Jeff learns about bear conservation and discovers the unique and friendly behaviors bear cubs have towards each other. Later, Jeff travels to Florida to meet orphaned baby manatees. Jeff learns about the threats to manatee habitat and what biologists are doing to save them. Finally, Jeff assists veterinarians to help two adorable opossums heal from their wounds and return to the forest. Video Transcript: Jeff Corwin: Mammals come in splendid variety, from the massive blue whale to the tiny deer mouse. Nearly all mammal mothers have live birth and all produce milk for feeding their young. At least some part of their bodies are typically covered with hair or fur at some point in their lives, and all mammals are endotherms, which means they can generate heat to maintain their warm-blooded body temperatures. Jeff Corwin: But tragically, today, nearly one quarter of all mammals are threatened with extinction, including at least 65 species in the United States alone. Scientists have estimated the total mass of all mammals on earth. They discovered that human beings make up 34% of this biomass, domesticated mammals account for 62%, which means only the remaining 4% are wild species. In the forests of New England, wild American black bears live in close proximity to humans. These bears are constantly threatened by pollution, vehicles and habitat loss, and black bear cubs are increasingly becoming orphaned. Jeff Corwin: Today, I'm visiting the Kilham Bear Center, where some of these bear cubs are given a second chance of survival.   Jeff Corwin: So this very precocious, absolutely adorable black bear cub is Marlow. This is Ethan Kilham and essentially Ethan, you are Marlow's stepmom, aren't you? Ethan Kilham: Yes. I'm the primary caregiver for the cubs, so basically I'm trying to be the best facsimile to a mother bear that I can be, so I'm feeding them, I'm introducing them to wild foods, wild things from the environment, stuff that they can play with. Jeff Corwin: Hi Marlow, no nibble. No, that's not... No, please. No, Marlow, no. So your instinct is to interact, but we don't want to interact. We want this bear to discover that human beings aren't a  part of his future success in life, right, Ethan? Ethan Kilham: Right. Jeff Corwin: We want him to be wild. Ethan Kilham: He'll be released at about 18 months of age and then he'll have all the tools to be a perfectly wild bear. Jeff Corwin: Marlow, what are you doing? Marlow, please get off the cameraman. Jeff Corwin: Marlow is still too young to be released, but today is a special day for two cubs named Flower and Dover. Today, they're going back in the wild and that's what we are about to do right now. For both our safety and the safety of these cubs, Flower and Dover will need to be sedated. To do this, Ryan will use a long pole fitted at the end with a small syringe of fast-acting sedative. Jeff Corwin: So what Ryan needs to do is get close to these bears, give them a quick poke, they'll go to sleep and all will be good. Jeff Corwin: No one likes getting a shot, especially a bear cub. Jeff Corwin: Success, Ryan? Ryan Smith: I think so. Jeff Corwin: Going to wait until he starts to get a little tipsy, which he is right now. We want to be there so when the bear goes to sleep, he doesn't fall and hurt itself.  Jeff Corwin: The sedative works very fast and makes Flower a little dizzy, but don't worry. We won't let him get hurt.  Jeff Corwin: There we go. There we go.  Jeff Corwin: We take Flower outside where the wildlife team will give him his final checkup. Jeff Corwin: So our first bear is nicely situated. Now let's go get the next bear. Jeff Corwin: All right. Okay. Now it's time for bear number two. Ryan's going to get in position. Thankfully, Dover's found a little corner to curl up in, so getting him outside will be much easier. Jeff Corwin: All right, if you just lower it down. Okay. I got him. All right. They are just such beautiful, beautiful creatures, so precious, such an important part of our wild legacy and to be a part of this program, it's amazing. Jeff Corwin: So what we have to remember is that these bears are no longer in control in the way their head is angled, their airway has opened or closed, and we have to constantly be vigilant to make sure these creatures aren't overheating, aren't stressed and are sleeping safe and sound. The team carefully records the cubs' temperatures, heart rate and size, what we call biometrics. Finally, it's time to give these cubs a small tag on each ear so they can be identified in the future... We've hit our character limit. Please leave us a comment for the rest of the transcript.

Join host Jeff Corwin for a celebration of the Endangered Species Act by connecting with a few of the amazing species that have benefitted from the landmark legislation. To learn more about the wildlife featured in the episode, visit www.defenders.org/wildlifenation Video Transcript: Jeff Corwin: The United States is home to some of the most spectacular landscapes and diverse wildlife on earth, and there's no better example than an iconic bird that's loved and admired from sea to shining sea.   Now that my friends is a powerful stare. For me, the bald eagle is not only a powerful symbol of the United States, but it is an incredible example of environmental stewardship, conservation, and the importance of the Endangered Species Act. Amazingly, not so long ago, this mighty bird species was pushed to the brink of extinction. But today, it is recovered and it is thriving because we all came together and we protected this amazing symbol of the United States. Jeff Corwin: The modern American environmental movement began in 1973 with the passage of landmark legislation called the Endangered Species Act. This crucial bipartisan law empowered our government to protect and manage vulnerable plants and animals, as well as the ecosystems upon which they depend. The Endangered Species Act has saved dozens of other threatened species from the brink of extinction, including one of my favorites, sea turtles. Today, we're exploring the beautiful beaches of Boca Raton, Florida, where several different sea turtle species make their nests. Jeff Corwin: This is Elizabeth Fleming, she works with Defenders of Wildlife. Her backyard is Florida. Her mission is Florida. This is David Anderson, and you're the sea turtle coordinator for Gumbo Limbo. David Anderson: Yes, I am the conservation coordinator for our five miles of beach in Boca Raton. Jeff Corwin: Awesome. Elizabeth, why are beaches like this critical to the survival of sea turtles? Elizabeth Fleming: Well, Florida is globally important for sea turtles. We have the largest nesting aggregations for loggerhead turtles in the entire world. Jeff Corwin: That's kind of amazing. Elizabeth Fleming: It's kind of amazing. Jeff Corwin: David, I think what's so special about Boca Raton is that a few decades ago, people had a sense of foresight. David Anderson: They had foresight to establish parks - beachfront parks in about half of all of Boca Raton's shoreline. Jeff Corwin: We've got a sea turtle nest right here. What species do you think? David Anderson: This is a loggerhead nest. This nest hatched three days ago, so now we are ready to excavate it and inventory its contents. Jeff Corwin: Awesome. Shall we start? David Anderson: Yes, we can start. Basically just start digging straight down, separate all the hatched shells. Elizabeth, can you help me sort. Elizabeth Fleming: I can. Jeff Corwin: Typically, how many stragglers would you find? David Anderson: I would say about half of the time we excavate nests, we find a live hatchling or two or sometimes three or four. Elizabeth Fleming: So they lay a lot of eggs and numbers are on their side to help them survive. Jeff Corwin: What's really promising is we're seeing a lot of empty shells. David Anderson: Right. Jeff Corwin: Which means, a lot of them got out alive. David Anderson: That's right. Elizabeth Fleming: One in 10,000 actually survive to become an adult and breed. The thing is if we just protect their habitat, they will do the rest. Jeff Corwin: They're indicator species. Elizabeth Fleming: Absolutely. Jeff Corwin: They're keystone species. Elizabeth Fleming: They are. Jeff Corwin: They're critical to the environment. They're a part of human culture. Elizabeth Fleming: They are. Jeff Corwin: It would be a sad world without them. Elizabeth Fleming: It sure would. Jeff Corwin: Oh, and it would be a sad world- Elizabeth Fleming: Did you find one? David Anderson: Look at there. Jeff Corwin: Look at that. Elizabeth Fleming: Look at that. Jeff Corwin: And it would be a sad world without this, and this is why this is so important. Because every sea turtle matters. This little straggler, buried deep in the nest, it's been liberated. In a little bit. David Anderson: Yep. Jeff Corwin: It's going home. Jeff Corwin: Of the seven sea turtle species roaming the oceans of our world, six of them make their nests on the beaches of America and all of them are listed as protected animals, under the Endangered Species Act.

Join host Jeff Corwin on an adventure through central Florida as he helps save threatened gopher tortoises from a new real estate development. Later, Jeff uncovers how gopher tortoises contribute to Florida’s entire ecosystem by providing important habitat for many other species. To learn more about the wildlife featured in the episode, visit www.defenders.org/wildlifenation Video Transcript: Jeff Corwin: Our adventure begins in Central Florida, where an amazing species of reptile has lived for  millions of years. Jeff Corwin: So friends, right now, we're working with an incredible project, and it's all about rescuing these amazing creatures. This is the incredible, the iconic, gopher tortoise. Kent, I can't think of a more amazing symbol of old wild Florida than this, but today they're in serious trouble. Why are these tortoises disappearing? Kent Wimmer: Because of development pressures and land uses that don't protect their habitat. Jeff Corwin: In Florida, neighborhoods are popping up left and right. How many people move here every day? Kent Wimmer: 1,000 people a day. Jeff Corwin: To make room for people, means we lose habitat, and a species like this depends on a very specific type of habitat. Jeff Corwin: Gopher tortoises are expert diggers. Every year, they dig out several long tunnels deep underground, where they are protected from weather, fires, and predators.  And these master excavators play a critical role in Florida's entire ecosystem. Kent Wimmer: Gopher tortoises are one of nature's engineers. Over 360 species live in gopher tortoise burrows. They're one of the most important species we have in Florida. Jeff Corwin: We've got Kent from Defenders, and we have Carissa who is from Saving Florida's Gopher Tortoises. Carissa, these tunnels can go how many feet? Carissa Kent: In the center of the State, they'll go down to 25, 35 feet. They dig to the water table. Jeff Corwin: You're talking about 25 feet down. Carissa Kent: Correct. Jeff Corwin: I'm not talking length- Carissa Kent: Length. Jeff Corwin: ... just down. Carissa Kent: Just down. Jeff Corwin: This sandy type soil you find in Florida is ideal for tortoises. But, it's also ideal for homesteading,  real estate, and construction, isn't it? Carissa Kent: Correct. So the same places that tortoises want to live, humans want to live. So, there has to be a balance there somewhere. So we work on projects, unfortunately, that had an old permit system, where the developers are able to purchase a permit to bury them alive. Jeff Corwin: Under Florida regulations, many older gopher tortoise permits still allow developers to destroy their burrows and seal them underground beneath layers of concrete. And many other species that live in their burrows, can be routinely killed.   Jeff Corwin: This lot, which is home to gopher tortoises, is now going to be ripped up, torn down, and made room for a development, a neighborhood. That's where Carissa's group with partners like Defenders come in. We've come to this place, to get whatever tortoises are living here out of harm's way. Because if we don't, they'll be forever buried under a neighborhood of concrete. Carissa Kent: Correct. Jeff Corwin: All right. Shall we go save some tortoises? Carissa Kent: I'm ready. Kent Wimmer: Let's go. Jeff Corwin: Let's do it. Carissa Kent: Let's go. Carissa Kent: All right, found one guys. Kent Wimmer: Hey. Carissa Kent: All right. It's right here. Jeff Corwin: All right. Yep, I can see that. Kent Wimmer: Good job. Carissa Kent: Yeah, I see tracks and some nice little trails right there. So, we're hoping this is definitely  a gopher tortoise that's physically in here. Jeff Corwin: There could be dozen of critters down there, but there's only one way to find out, and we've  got some technology to do that, don't we Carissa? Carissa Kent: We sure do. Jeff Corwin: Carissa carefully feeds a small camera deep into the hole, to see if anyone is at home. Carissa: All right. It's curving to the left a little bit. And- Jeff Corwin: Look at that. A tortoise. Carissa Kent: There is our tortoise. Kent Wimmer: All right. Jeff Corwin: So, we've confirmed tortoise, what do we do? Carissa Kent: It's time to excavate. Jeff Corwin: All right, let's do it. Carissa Kent: All right, let's go. Kent Wimmer: All right. Jeff Corwin: In order to safely excavate the gopher tortoise, we rely on some heavy-duty industrial earth moving equipment to help clear away the top soil. Jeff Corwin: This is about being very, very gentle and approaching this hole as gingerly as possible, isn't it? Carissa Kent: Absolutely. Obviously, we're digging with very, very large machinery here, so our number one goal is not to hurt this tortoise. But we need this machine to get this tortoise out of the ground. So how we do that, is delicately. We've hit our character limit. Leave us a comment for the rest of the transcript.

Jeff Corwin begins in the historic city of Boston to help aid the recovery of peregrine falcons with Defenders of Wildlife staff. To learn more about the wildlife featured in the episode, visit www.defenders.org/wildlifenation Video Transcript: Jeff Corwin: For today's adventure, we're heading to my home state of Massachusetts and a place called Deer Island in the middle of Boston Harbor.  This island is the location of a state of the art  massive wastewater treatment plant that cleans over 1200 million gallons of wastewater every day. It's also home for a family of peregrine falcons, the fastest animals on earth, capable of  reaching speeds of more than 200 miles an hour.   Jeff Corwin: I'm with Jacob Malcolm. He's the director of Defenders of Wildlife's Center for Conservation Innovation. So basically, you guys are trying to figure out how you integrate technology with policy and environmental stewardship to make it work. Dr. Jacob Malcolm: Yep. It's one of the most exciting parts about my work, is the fact that we get to work on solutions. It's really overlooked often that we do have lots of opportunities to do more for wildlife. Jeff Corwin: The peregrine falcons that live here are a perfect example of this. In the wild, falcons typically build their nests on high cliffs. So to give this species a helping hand in a dense urban environment, the Massachusetts Department of Fisheries and Wildlife have teamed up with the Massachusetts Water Resource Authority to put a special nesting box at the top of this 130 foot tall filtration tank. For a family of peregrine falcons, this is the perfect penthouse. Jeff Corwin: I mean, that's kind of amazing, right? With a little bit of ingenuity and a little bit of environmental  stewardship, you can find that balance where creatures like the ultimate bird of prey can share a habitat that also belongs to human beings. Dr. Jacob Malcolm: The fact that we're here to band some peregrine falcons at a wastewater treatment facility with Boston right there just goes to prove it. Jeff Corwin: Jacob is a wildlife biologist, but you've never banded a peregrine falcon. Dr. Jacob Malcolm: I have not. Jeff Corwin: You ready? Dr. Jacob Malcolm: I'm ready. Jeff Corwin: All right, let's do it. Dr. Jacob Malcolm: Let's do it. Jeff Corwin:  In one of the most successful conservation stories in the history of our country, peregrine falcons were brought back from the brink of extinction, thanks to decades of hard work by dedicated people and organizations. To keep track of this species' recovery, biologists place small identification bands around the legs of every falcon chick they find. Today, we're helping wildlife biologist, Dave Paulson, and his team from the Massachusetts Division of Fisheries and Wildlife to band the falcon chicks that live at the top of this tower. Jeff Corwin: But first, we'll need to face some strong winds and some very devoted and determined parents. Dave Paulson: Now, Jeff, be real careful with this. Jeff Corwin: Be real careful. Wow. Jeff Corwin: As soon as we open the door, we see her, a mother peregrine falcon, ready to protect her nest and her offspring at any cost.  As soon as we remove the guardrails and step onto the catwalk... Dave Paulson: She's coming right in for you. Jeff Corwin: She begins to dive bomb our team with incredible speed. Dave Paulson: Coming in hot. She's coming in from below. Come on go right to the box. Jeff Corwin:  This right here is a nesting box for a peregrine falcon. Dave Paulson: She's getting close, getting close, getting close. Jeff Corwin: Above us we have two very, very devoted, I would say slightly aggressive. Dave Paulson: Yep. Jeff Corwin: Peregrine falcons. They're a bonded pair. And this female, she wants us to have nothing to do with her next generation, what for her is the most precious thing in the world. Dave Paulson: I know everyone's focused on her, but if someone wants to keep a peripheral open for or the other one. Dave Paulson: Right up there. Jeff Corwin: We got to be very careful. We're being dive bombed by these parents. And it's a long way down. Dr. Jacob Malcolm: It is. Jeff Corwin: So inside we have... Ah, look at that. We have these. Oh my gosh. Look at this. Look at that. Dr. Jacob Malcolm: It's fantastic. Gigantic eye, sharp beak, great talons. Built for speed and flight. Jeff Corwin: Just take a moment to reflect at what we're doing. We're holding a species that in this part of  the world was extinct for almost 30 years. Today we have 50 pairs successfully surviving and breeding. Dave Paulson: Correct, 50 known pairs here in Massachusetts. And the big thing here is most of these aren't  on natural cliff sites. You're talking buildings, bridges, quarries. They've really take  to the developed landscape really well. We've hit our character limit. Leave us a comment for the rest of the transcript.
