What do we think is the future of the bald eagle?

The bald eagle was once in a time where everyone thought its numbers were going to be reduced to 0. But then, they decided to do something about it. So now, the future of the bald eagle is a bright one. And at least for the next fifty years, there is no chance our country will have an extinct bird as our national bird.

What do we think could help protect the bald eagle?

I think that if the government made a harsher punishment for eagle hunting, it wouldn't be done as often. They could also put cameras in the more populated bald eagle areas so if one is hunted and killed we would know who did it.

Has there been any effort to protect the bald eagle?

There has been a big effort to protect the bald eagle! For example, in 1940 the Bald Eagle Protection Act was passed. That made it illegal to possess (without a permit), kill, harass, or sell bald eagles. Another thing that was killing many eagles was the use of the pesticide DDT. Luckily, it was banned by EPA in 1972.

What would happen if bald eagles went extinct?

It would actually be very bad if they went extinct. The bald eagle is a fishing eagle, so it catches the fish then takes it out into the trees or wherever they eat it. Then the leftover bits of fish get fertilized directly into the soil, or decomposers break it down and release nutrients that fertilize the plants. So if bald eagles went extinct the plants would become less fertile which means that the consumers who eat the producers will have to eat more to get their fill, the plants will run out, and any animal that eats those animals will become extinct as well until the whole food chain is out of whack.

What do we think is the future of the mangroves?

The answer to that question depends. If people don't realize that the mangrove is going extinct like we did with the bald eagle, then my guess is that by 2030 there will be less than 1,000 acres of mangroves left. But if we continue to do things to help them and restore part of the everglades, then the mangroves have a bright future and will continue to live and thrive in the world.

How close is the bald eagle to extinction?

It was on the endangered list in the 1960's, but then people actually realized it and did many things to save it. So now, it is off the endangered list and not even close to extinction.

What do we think could help the ecosystem?

To help the ecosystem, the government could just protect all of the mangroves instead of just part o f it, or what they could do is get about one acre of mangroves that is the least contributive, evacuate it of mangroves, and let whoever wants to cut down mangroves use that.

Have the methods helped the mangroves?

Yes, approximately 280,000 acres of mangrove forests are in the hands of the federal and local government, and non-profit organizations. Although, most of those acres are in the Everglades.

What role does the bald eagle play in the environment?

The bald eagle does an important job that keeps the food chain intact. It protects overpopulation in ponds and river areas. If bald eagles die out, then the mice, rabbits, fish, and other things that the bald eagle eats will become overpopulated. Then they will eat the producers faster than they can grow, until there won't be any plants left. Once that happens, the mice and rabbits will die out because they have no food. Then anything that eats those will die out because they have no food, until the whole ecosystem is out of whack.

How are people trying to help mangroves?

Now that the mangroves are actually getting seriously depleted, people are trying to help them. One of the ways is encasing the mangrove saplings in PVC tubing to provide protection and support until they can get established. Another way is restoring mangroves not through planting, but through engineered site elevations and the removal of dredge spoils. The Florida Government is also protecting some mangrove areas.

Have Bald Eagles been affected by the mangrove depletion?

If the bald eagle lives in a mangrove and the mangrove is getting cut down, then probably yes! The eagle likes to make its nest up high, where it can perch and hunt. So imagine that you lived in a tree house and someone cut your tree down to build a house. Then you move to another tree but they cut that house down to build a table. And you keep moving from tree to tree as they keep on getting cut down. Eventually, there aren't going to be any trees left for you to live in. That's the situation with the bald eagle. And why would you want to ruin the home of such a majestic bird?

Has mangrove depletion caused problems?

If you cut down mangroves, then you will cause some problems. Like I said in one of my earlier  posts, mangroves are what protect the uplands from wind, storms, rains, and floods. They provide food for many tiny animals, and 75% of game fish and 90% of commercial species in South Florida rely on mangroves for shelter. They also absorb nutrients into their roots, so if you take out mangroves you are causing a lot more problems than you think.

What adaptations does the Bald Eagle have?

The Bald Eagle has several adaptations that help it survive in the wild. One is that it can see four to eight times better than any human, which helps it see prey from further away. Another is that it has an overhang above its eyes which helps shield it from the sun while hunting. It also has little bumps on its feet to help it grasp fish while flying. Along with that, the most obvious one is that its curved, sharp beak helps it dig into food and tear the meat. And finally, during the winter its feathers fluff up to keep the eagle warm, then in the spring and summer they become normal, and in the fall they start to fluff again.

Why have mangroves depleted?

The reasons mangroves have been disappearing so much may sound ridiculous, but they can be very convincing. It could be simply for urbanization, so that we could have more tourists and more people living here. It could be for agricultural purposes, so they can make the landscape the way we want it. Or maybe it could be because of aqua-cultural purposes because the people want a new pond by the new condo. Mangroves can also disappear because they are being used for timber, charcoal, or fuel, and also to prevent freshwater and tidal flow. Oil pollution, or just pollution in general, can also make mangroves die. And these are just some of the human causes. There are also invasive species and climate change that kill mangroves, which is why we need to double our efforts to save them, before they are all gone.

Bald Eagle Taxonomy

Hm... I wonder what the bald eagle taxonomy is?
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Falconiformes
Family: Accipitridae
Genus: Haliaeetus
Species: Haliaeetus leucocephalus

How have mangroves changed?

You may ask yourself: how have the mangroves changed? I mean, can they really change that much? The answer is, yes they can. Over the past 100 years, Tampa Bay has lost over 44% of their costal wetlands acreage, which includes mangroves and salt marshes. Lake Worth, near West Palm Beach, has had an 87% decrease in its mangrove acreage and has just 276 acres left. The Indian River has lost 86% of its mangrove areas to fisheries since the 1940's, and now laws have been enforced to make sure the mangroves are protected. But doesn't looking at these numbers make you think how much better the world would be if those mangroves were still here? We might lose a lot of buildings, but how can you compare a city to the open environment? Think of ideas you can use to make a change and use them.

Bald Eagle

Now, this is a bird that you have to know. If you don't know it, then you don't know the most well-known bird, the national bird, and probably the most majestic bird. It was actually considered endangered in almost all states until 1995. In July of that year, it was taken off the endangered list but it was still on the threatened list. Then in June 2007 it was actually taken off endangered and threatened. But, it is still illegal to take, sell, poach, etc. bald eagles.

The mangroves...

The mangroves. So misunderstood. Most people can hardly recognize them and just plow through without any second thought as to how they might be important. Even if they do think about it, this is probably going through their mind. "It's just a couple of trees... How important can they be?"  But when you are tearing down those "couple of trees", you are ruining an important part of our ecosystem. Mangroves protect uplands from winds, storms, rains, and floods. 75% of game fish and 90% of commercial species in South Florida rely on those. So when you ruin the mangrove forest you are ruining the thing that almost all of our fish are dependent on. They provide shelter for many birds, help prevent erosion, and provide food for multiple species. And after you tear down four square miles of mangroves to make room for a few condos, you can think back to all the animals you are destroying and all the shelter and protection you are getting rid of.http://www3.leegov.com/dcd/Environmental/Mangroves.htm
