So what's up? 00:00:00
Will the treehouse detectives find any endangered animals 00:00:01
in Jacob's backyard? 00:00:04
Will Kaylee get her Girl Scout badge? 00:00:06
What else should the detectives do 00:00:08
to help Jacob get a certified habitat? 00:00:10
Find out in the exciting conclusion 00:00:12
of The Case of the Zany Animal Antics. 00:00:14
Be sure to look for answers to the following questions. 00:00:20
What criteria are used to classify an animal 00:00:23
as endangered? 00:00:26
What is exploitation? 00:00:28
What are the three levels of endangerment? 00:00:30
How many breeding pairs of bald eagles 00:00:33
are currently in the US? 00:00:35
That's awesome. 00:00:37
I know. 00:00:38
I never thought it could happen, 00:00:41
but I may have actually discovered a species 00:00:42
that we could help. 00:00:44
Are you sure it's an endangered species and that we can help? 00:00:45
I think it's endangered. 00:00:49
I'm not sure exactly. 00:00:50
Did you get any information from NASA 00:00:52
about how to determine if a species is endangered? 00:00:53
No, but I did get a lead. 00:00:56
Dr. Bruninger works with lots of NASA researchers 00:00:58
who work with endangered species. 00:01:00
I'll try to contact him. 00:01:02
Good idea. 00:01:04
You know, it's strange, but I never 00:01:05
thought I could actually help out an animal, possibly 00:01:07
even an endangered one, in my own backyard. 00:01:10
It's kind of cool. 00:01:13
Yes, but you're getting ahead of yourself. 00:01:14
First, we need some more answers. 00:01:17
Here's Mr. Scheidt. 00:01:19
He works with endangered species at NASA Kennedy. 00:01:21
Hi, Mr. Scheidt. 00:01:24
I understand you want to learn about endangered animals. 00:01:26
Yes, but we're not even sure how we 00:01:29
know a species is endangered. 00:01:30
The Endangered Species Act says that any species that 00:01:32
is in danger of becoming extinct throughout all 00:01:35
or a significant portion of its range 00:01:37
can be classified as endangered. 00:01:39
What kind of things cause animals to become endangered? 00:01:41
Loss of habitat is one way. 00:01:44
We learned that an animal's habitat 00:01:46
is very important to providing its basic needs. 00:01:48
That's right. 00:01:50
If an animal's habitat is greatly altered, reduced, 00:01:51
or destroyed, it can have a significant impact 00:01:54
on the species. 00:01:56
We also learned that in addition to fire and storms, 00:01:57
people have a big effect on an animal's habitat. 00:02:00
Yes, human impacts can have serious effects on habitat. 00:02:03
For example, water and or air pollution 00:02:06
can restrict plant growth or harm a habitat. 00:02:08
Exploitation is another way it can endanger a species. 00:02:11
What do you mean by exploitation? 00:02:15
Exploitation is where a species population is reduced to a point 00:02:17
that it cannot reproduce fast enough to sustain itself. 00:02:21
How are animals exploited? 00:02:24
Take the Manti, for example. 00:02:26
In the 18th and 19th century, they 00:02:28
were hunted extensively for their meat, fat, 00:02:30
and tough hides, which greatly reduced their population. 00:02:32
Currently, residential and commercial development 00:02:36
along the coast has also degraded their habitat, 00:02:38
thus decreasing their population. 00:02:41
Sort of like what happened to the buffalo in the plains. 00:02:42
They were hunted until there were hardly any left. 00:02:45
But I think they're making a comeback. 00:02:48
Are there levels of endangerment? 00:02:50
Yes, the US Fish and Wildlife Service has three levels. 00:02:52
Endangered is the most severe. 00:02:56
Threatened is when a species is likely 00:02:57
to become endangered within the foreseeable future 00:02:59
throughout all or most of its range. 00:03:01
And last are species of special concern. 00:03:03
What's that? 00:03:06
It's when a species may need a conservation action. 00:03:07
This usually means periodic monitoring 00:03:10
of the species population or its habitat. 00:03:12
Do most become threatened or endangered? 00:03:15
No, not always. 00:03:17
Sometimes, if we become aware of the problem early enough, 00:03:19
we can remedy it before the species gets to that point. 00:03:22
How many animals are on the endangered species list? 00:03:24
There are over 900 species of plants and animals on the list. 00:03:27
How many are there in NASA Kennedy? 00:03:31
Kennedy Space Center is actually home to 10 endangered species. 00:03:33
Of course, these species aren't endangered due to the Space 00:03:36
Center, but are actually protected by Kennedy Space 00:03:39
Center, since it is so large and covers so many different types 00:03:41
of habitats. 00:03:44
Did you know that only 6% of the Space Center 00:03:45
is used for space launch operations? 00:03:48
And the rest is Merritt Island National Wildlife Refuge. 00:03:50
That's right. 00:03:53
We not only have programs to protect these species, 00:03:54
but we also conduct research to aid in their recovery. 00:03:56
Do you ever have to rescue animals? 00:03:59
Yes. 00:04:01
Sometimes, when we encounter an injured or distressed animal, 00:04:02
we do our best to stabilize the animal 00:04:05
until a rescue team arrives. 00:04:07
Who helps you rescue the animals? 00:04:09
We work closely with state and federal agencies, 00:04:11
along with private organizations such as SeaWorld. 00:04:14
You may want to go to SeaWorld and talk to Dr. Beth Chittick, 00:04:17
a veterinarian that works with the SeaWorld Rescue Program. 00:04:20
Thanks, Mr. Scheidt. 00:04:23
This has been fascinating information. 00:04:24
You're welcome. 00:04:26
SeaWorld Rescue Program? 00:04:27
Sounds awesome. 00:04:29
Yes, it does. 00:04:30
And it sounds like it's right up RJ's alley, 00:04:31
since he's still down in Florida. 00:04:33
You send him an email, while I go 00:04:35
check on our endangered species. 00:04:37
I hope you know what you're doing, Jacob. 00:04:38
Remember, this is me we're talking about. 00:04:40
I'm here in Florida with Dr. Beth Chittick, 00:04:43
a veterinarian who works at SeaWorld. 00:04:45
She has a real inside scoop on why SeaWorld 00:04:48
rescues and rehabilitates animals. 00:04:50
SeaWorld is committed to wildlife conservation. 00:04:53
Our rescue programs allow us to help animals 00:04:56
and also learn more about them at the same time. 00:04:59
What kind of animals do you rescue? 00:05:01
The four main animal groups we rescue 00:05:03
are sea turtles, aquatic birds, manatees, and dolphins. 00:05:04
What about an animal injured by natural causes? 00:05:08
We rescue those animals that are sick or injured 00:05:11
or who need medical attention in order to survive, 00:05:14
regardless of the cause. 00:05:16
For example, sometimes manatees become cold stressed 00:05:18
in the winter, which is natural. 00:05:21
But we would still attempt to rescue them, 00:05:23
especially since they are in danger. 00:05:24
So if a manatee or dolphin is sick enough to be rescued, 00:05:26
what do you do? 00:05:29
We mobilize our crew and equipment 00:05:30
and head to the site where the animal is located. 00:05:32
We approach it slowly and encircle it with a net. 00:05:34
We then pull that net out of the water 00:05:38
and transport the animal to our rescue vehicle. 00:05:40
Do you treat an animal right away 00:05:43
or do you wait until they get back to SeaWorld? 00:05:45
If the injury is minor, the animal 00:05:47
can be treated and released. 00:05:49
If the animal is more seriously sick or injured, 00:05:51
it receives a full exam during transport, 00:05:54
and if any initial treatment is needed, 00:05:56
we give it right away. 00:05:58
What happens to the animal once it arrives here? 00:05:59
We're a lot like a hospital. 00:06:02
Once an animal arrives, we do tests 00:06:04
such as take blood samples and x-rays 00:06:06
to help us determine what's wrong with the animal. 00:06:09
Once we know what the problem is, 00:06:11
then we can devise a plan to treat it. 00:06:13
So when the animal gets well, it gets to go home? 00:06:15
Yes. 00:06:17
Once it is rehabilitated and ready for release, 00:06:18
SeaWorld works with the appropriate government agency 00:06:20
to determine when and where to release the animal, 00:06:23
usually as close as possible to where we rescued it. 00:06:26
What about the animals that can't be rehabilitated? 00:06:28
It is our goal to release all rescued animals if possible. 00:06:31
However, if an animal's injuries 00:06:34
keep them from being able to survive on their own in the wild, 00:06:36
we would either keep them here or find them another home. 00:06:39
I know you can't save every manatee that's sick or injured, 00:06:42
but you do save a lot of them, right? 00:06:45
Yes. 00:06:47
We have rescued 324 manatees 00:06:48
and released 121 back into the wild. 00:06:50
Mr. Scheidt at NASA Kennedy 00:06:53
says that sometimes NASA works with SeaWorld to rescue animals. 00:06:55
Do you work with any other organizations? 00:06:58
Yes. 00:07:00
And you should meet Miss Jenny Bush. 00:07:01
She is president of our SeaWorld Bush Gardens Conservation Fund 00:07:03
and can answer that question for you. 00:07:07
I think she's working with one of the eagles today in the park. 00:07:09
Hi, Miss Bush. 00:07:13
Hi, RJ. This is Maddie. 00:07:14
She's from the Audubon Bird of Prey Center. 00:07:16
She fell out of her tree when she was 5 weeks old. 00:07:18
Is she okay now? 00:07:20
Maddie is okay now, but after 8 months of rehabilitation, 00:07:22
she was deemed non-releasable, 00:07:25
so she trains here at SeaWorld to become an animal ambassador. 00:07:27
Aren't bald eagles endangered? 00:07:30
Bald eagles are a great success story. 00:07:32
Just 50 years ago, they were very endangered, 00:07:34
but now through conservation efforts and awareness, 00:07:36
there are over 7,000 pairs, and they're protected. 00:07:38
Wow. That's a lot of eagle families. 00:07:41
It's a great story to tell, and we hope in the future 00:07:43
that we can help many more animals just like the bald eagle. 00:07:46
How will you do that? 00:07:48
Through the efforts of the SeaWorld Bush Gardens Conservation Fund. 00:07:50
What exactly is the conservation fund? 00:07:52
Well, the fund is a non-profit organization 00:07:54
that helps to grant monies to other organizations 00:07:57
like World Wildlife Fund, National Wildlife Federation, 00:08:00
to go towards projects like conservation education, 00:08:02
habitat protection, species research, 00:08:05
both marine and terrestrial, and rescue and rehabilitation. 00:08:07
What kind of research do you do? 00:08:11
Well, the SeaWorld Bush Gardens Conservation Fund 00:08:13
grants monies to many different projects in the field, 00:08:15
from protecting black rhinos in Africa 00:08:17
to protecting coral reefs in South America. 00:08:19
Our five zoological parks participate in research as well, 00:08:21
from creating a better flotation device for ill manatees 00:08:24
to also learning how killer whales communicate. 00:08:27
I learned a thing or two about taking care of animals 00:08:29
this week at adventure camp. 00:08:31
Well, I imagine it hasn't been as easy as you thought it would be. 00:08:33
That's for sure. 00:08:35
It's definitely a career I'm interested in learning more about. 00:08:37
Yes, working with animals is very rewarding. 00:08:39
You should try the marine mammal keeper experience here at SeaWorld. 00:08:41
That's great. 00:08:44
It sure sounds like you're committed to helping the animals and the environment. 00:08:46
Yes, SeaWorld and Bush Gardens have been environmental stewards 00:08:49
for over 40 years. 00:08:51
Thanks, Ms. Bush. This has been great. 00:08:53
You're welcome, RJ. Enjoy the rest of your time at camp. 00:08:55
Thank you. 00:08:58
Bianca, did you get RJ's report? 00:09:05
Yes, it has all kinds of information 00:09:07
on how injured and endangered animals are taken care of. 00:09:09
He's getting really good work done. 00:09:12
Yes, it is all coming together. 00:09:14
What's coming together? 00:09:17
Well, you know how Catherine wanted to protect animals. 00:09:19
Yes. 00:09:21
And Kaylee needed to protect an endangered species to get a wildlife badge. 00:09:23
And it was your idea to turn my backyard into a habitat. 00:09:26
Thank you. Yes. 00:09:28
Well, it all just might work. 00:09:31
I've got to go to my house and get Tony and Catherine, 00:09:33
and then we're going to Mr. Kutchin's to meet Kaylee. 00:09:35
Who is Mr. Kutchin? 00:09:38
He has an official backyard habitat. 00:09:40
Dr. D is going to meet us there 00:09:42
to give us an idea of what goes into an actual habitat. 00:09:44
That's great, but how does all that relate to endangered species? 00:09:47
Kaylee built a bat house for eastern big-eared bats, 00:09:51
but she has no place to put it. 00:09:53
Well, they're endangered, 00:09:55
and it turns out my backyard is in their range. 00:09:57
Jacob, that's great. 00:10:00
You've helped Catherine and Kaylee. 00:10:02
Yes, but I have one obstacle left. 00:10:04
Can you check my e-mail? 00:10:07
Are you expecting official notification for your yard? 00:10:09
Sort of. 00:10:11
All you have is a letter from your mom. 00:10:13
What's it say? 00:10:15
One word, okay. 00:10:17
Yes! I've got to go. 00:10:19
I'll never understand him. 00:10:21
Wow, Mr. Kutchin has a great backyard habitat. 00:10:26
Look, he even has a cool plaque 00:10:30
indicating he's certified by the National Wildlife Federation. 00:10:32
You have to provide food, water, shelter, 00:10:35
and a place for animals to raise their young 00:10:38
if you want to be certified. 00:10:40
That makes sense. 00:10:42
That's the list of animals' basic needs. 00:10:44
The habitat also has to be managed 00:10:46
to conserve soil and water. 00:10:48
You have a lot of work to do 00:10:50
to get your backyard up to this level. 00:10:52
But it'll be worth it. 00:10:54
Did you get your wildlife badge? 00:10:56
Well, I've done all my research, 00:10:58
and I finished my bat house, 00:11:00
but I haven't found a suitable habitat for it. 00:11:02
Is that your bat house over there? 00:11:05
Yeah, I brought it today so you could see it. 00:11:07
Cool. 00:11:09
But it's hard to believe bats could fit in there. 00:11:11
Actually, that can hold up to 50 bats. 00:11:14
Hi, guys, we're Tony and Catherine. 00:11:17
Aren't they supposed to meet us here? 00:11:19
They're in my house working on an observation area 00:11:21
and fee structure for our habitat. 00:11:23
Catherine should keep them under control. 00:11:25
I'm sure she will. 00:11:27
Okay, you've learned a lot about vertebrates and invertebrates. 00:11:29
Look around and tell me which animals 00:11:31
you think this backyard habitat will support. 00:11:33
That's easy. 00:11:35
We know there are 5 types of vertebrates, 00:11:37
and I bet we can find one of each in this backyard. 00:11:39
Right. I bet there are lots of birds. 00:11:41
Mr. Cutchin told us these flowers attract hummingbirds. 00:11:43
And that bird feeder and bird bath 00:11:46
should help attract migrating birds. 00:11:48
And those nesting boxes provide a place to raise young birds. 00:11:50
That looks like a squirrel house. 00:11:53
And these logs and bushes would provide good shelter for rabbits. 00:11:55
Those are both mammals. 00:11:58
Frogs and amphibians. I'm sure we'll find them here. 00:12:00
And don't forget reptiles. 00:12:02
We might see a snake, lizard, or turtle. 00:12:04
There aren't any fish, 00:12:06
but that might happen in a later addition to the habitat. 00:12:08
Don't forget the invertebrates. 00:12:10
I'm sure the annelidophyllum will help the garden. 00:12:12
Oh, you mean earthworms. 00:12:15
And I know we'll see lots of insects, which are arthropoda, 00:12:18
like beetles, ladybugs, flies, and mosquitoes. 00:12:21
You've learned your lessons well. 00:12:24
So why are backyard habitats so important? 00:12:26
Loss of habitat is the number one threat to wildlife. 00:12:29
And increasing the habitat increases the populations of animals. 00:12:32
You know, the carrying capacity will go up. 00:12:36
And they are beautiful. 00:12:38
I mean, they are great for thoughtful reflection. 00:12:42
Creating backyard habitats helps restore the balance of nature. 00:12:47
As you can see here, you don't need a big space to make a difference. 00:12:50
This is an excellent example of a habitat, 00:12:54
but it does seem to be missing something. 00:12:57
Like what? 00:12:59
I don't see any special accommodations for an endangered species. 00:13:01
Well, neither does our habitat. 00:13:04
That, young Kaylee, is where you are wrong. 00:13:06
In fact, you are the exact reason why my backyard habitat is going to be a success. 00:13:08
What are you talking about? 00:13:12
I had a serious discussion with my mom, 00:13:14
and after a little extra yard work, 00:13:16
I was able to convince her to let me put your bat house in my backyard. 00:13:19
Do you have bats in your backyard? 00:13:22
Not yet, but research indicates that over 50% of all bat houses are occupied, 00:13:25
and I'm feeling lucky. 00:13:30
I also spoke with your scout leader. 00:13:32
Let me be the first to congratulate you on earning your wildlife badge. 00:13:34
What do you mean? 00:13:37
Well, I knew you had built the bat house, 00:13:38
but you hadn't found a good place to put it yet. 00:13:40
It turns out that my house is in the area where eastern big-eared bats live. 00:13:42
So by placing your bat house there, 00:13:45
you are providing top-notch accommodations for an endangered species. 00:13:47
Jacob, you're the best. 00:13:50
Yes, like I've always said, 00:13:52
underneath this harsh exterior lies a peaceful, nature-loving man. 00:13:55
Good work, kids. I look forward to seeing your habitat. 00:14:00
There's only one small problem. 00:14:03
What is it? 00:14:05
How can we help? 00:14:06
Well, I'm actually terrified of bats. 00:14:07
Maybe I can move into the treehouse permanently. 00:14:11
Jacob, I don't think the treehouse is ready to support your species long-term. 00:14:13
We'd like to thank you for your support. 00:14:41
We're looking forward to seeing you again. 00:14:43
Thank you. 00:14:45
