Why Do Endangered Species Matter?

When we talk about endangered species, we mean an organism with population numbers so low that it is in danger of becoming extinct. While extinction is a natural process that has been happening throughout time (think dinosaurs, mammoths, sabre-toothed tigers), the rate of present day extinctions are alarming. WHY THE INCREASE IN ENDANGERED SPECIES?

Some scientists calculate present day extinction rate for plants and to be 1000 to 10000 higher than the natural “background rate” with dozens of species going extinct daily. What is causing this surge in extinctions?

Scientists believe that 99% of current endangered and threatened species are at risk of extinction because of human activities. These activities include habitat destruction, spread of disease, pollution, introduction of non-native species, hunting, and global warming. WHY LEARN ABOUT ENDANGERED SPECIES?

Each ecosystem on Earth is full of life that lives together symbiotically. This means that each one is needed for the survival and prosperity of the others. When an organism is removed, it is up to another to fill its role or the rest of the ecosystem will feel the effects. We need to understand that biodiversity is important. Endangered species in such large numbers are our environmental canaries in the coal mine. They are indicators of problems in the ecosystem. Learning about these organisms and their role in nature can help us not only bring back their populations, but help to end the factors that threatened them in the first place. 5 ENDANGERED SPECIES YOU SHOULD KNOW ABOUT

In this ebook, we are going to learn about five endangered species that are facing a variety to conditions that are causing their populations to decrease at an alarming rate. If action is not taken, these species will become extinct very soon.

Hopefully, after reading this book and studying these animals you will develop an appreciation of biodiversity, an understanding of why endangered species should cause us concern, and what you can do to help their recovery. REPORT PRINTABLE

There are over 4,000 bee species in North America alone. 50 of those species are considered bumble bees. Bumble bees are often what we picture when we think of bees: black and yellow, fat, and fuzzy. Rusty Patch Bumble Bees Facts

One North American bumble bee of recent interest is the Rusty Patch Bumble Bee. Rusty Patch Bumble Bees are naturally found in the tall grass prairie and grasslands of the upper midwest and northeast regions of the United States. Historically, their range reached from eastern North Dakota to Maine and Quebec, south to northern Georgia. They live in colonies in abandon rodent burrows and other ground cavities.

Rusty Patch Bumble Bees are relatively large bumble bees and can be identified by their black heads, yellow abdomens, and black rear sections. What sets these bees apart are the rust-colored patch on the back of their abdomens.

The Decline Of The Rusty Patch Bumble Bees

Up until the late 1990s, the Rusty Patch Bumble Bee was a fairly common bumble bee in its natural range that included 28 U.S. states and 2 Canadian provinces. Since 2000, they have only been found in 13 states and 1 province. A field study from 2007-2009 revealed that the historic range of the Rusty Patch Bumble Bee had decreased by 85% and the population had decreased by 95%.

Research has suggested that the decline in Rusty Patch Bumble Bee populations are due to introduced commercial bee species, habitat destruction, and pesticide use.

Because of the recent decline in numbers of pollinators in general, farmers have noticed a decrease in crop production. Buying and releasing commercially raised bees for pollination purposes seemed like a great idea. The only problem is that some of those bees spread a pathogenic fungus, Nosema bombi, throughout the North Americas bee population. The wild bees had little resistance to this pathogen and died.

Habitat destruction is a problem for many species. The Rusty Patch Bumble Bee thrives in open tall grass areas such as prairies where they can have access to many flowering plants and safe places to grow their colonies. Most of the grassy prairies of North America are now tilled for agriculture.

Along with agriculture comes pesticide use. Pesticides are sprayed on crops on the former prairies to protect them from pests that might eat the plants. These chemicals, also, kill the bees who live in and near these fields. Pesticides sprayed in gardens and flower beds are just as harmful.

This alarming decline has cause the Rusty Patch Bumble Bee to be places on the endangered species list in March 2017. It is the first bee in the U.S. to be added to the endangered species list, but unfortunately, probably not the last. Why We Should Care About Rusty Patch Bumble Bees

Like all bees, Rusty Patch Bumble Bees are important pollinators. They eat the nectar from a variety of flowering plants, and in the process, transfer pollen. According to a report published by the government of Canada, these bees pollinate up to 65 different species of plants, including key food crops, such as cranberries, plums, apples, onions, and alfalfa.

A report by the NRDC.org stated that bees in general pollinate $15 billion in U.S. crops. Bees are not just good for nature, they are good for our food supply and economy.

The Rusty Patch Bumble Bees are just one of 50 species of bumble bees and one of over 4,000 species of bees in North America. So what if one species disappears? The Rusty Patch Bumble Bees are one bee species of many that have seen a sharp decline. If we do not stop the conditions that are creating the demise of this species, similar species will follow suit. Our ecosystems needs a variety of bees and in adequate numbers for a good balance. Different bees pollinate different flowers. A healthy ecosystem has lots of flowering plants and needs a good number of pollinators. How To Help The Rusty Patch Bumble Bee

Many people across the country are waking up to the growing problem of rapidly declining bee populations. Of the over 4,000 species of bees in North America alone, half of them are seeing a sudden decrease in numbers.

Organizations, universities, and government agencies are conducting research and rolling out programs to protect and revive these species. These include working with farmers and land owners to reduce the amount of pesticide used or find alternative pest control practices, planting cover crops, planting native grasses, and improve the management of grazing lands.

These large groups of people aren't the only ones who can work to save the Rusty Patch Bumble Bee. You can do any or all of the following.

Build a pollinator garden by adding flowering plants to your yard that bloom spring to fall. Plant native grasses and plants. Do not use pesticides. Leave undisturbed grassy areas where bumble bees might live.

Can The Dusky Gopher Frog Be Saved?

The story of the Dusky Gopher Frog, or , is an interesting one. This once was found in abundance in the longleaf pine forests of southern Louisiana, southern Alabama, and southern Mississippi. Now, the Dusky Gopher Frog is only found in 3 ponds in Mississippi. In 2012, the IUCN (International Union for the Conservation of Nature) identified the Dusky Gopher Frog as one of the top 100 most endangered species in the world.

Dusky Gopher Frog Facts

Considered a mid sized frog with the adults being 3 inches long Dark colored ranging from black to gray to brown with dark spots and warts on their backs Feeds on insects, worms, spiders, and judging by the size of its large mouth, possibly other and toads Male calls sound like a snoring human Have been known to call underwater When threatened, the frog defends itself by inflating the body and secreting a pungent, bitter, milky liquid from the warts on its back When exposed to light it covers its eyes with its front feet Live in burrows created by the Gopher Tortoise, hense their name Mostly found in the longleaf pine forests Adults breed in fishless, shallow, temporary wetlands within the longleaf pine forests Why Is The Dusky Gopher Frog Endangered?

Longleaf pine forests historically covered 90 million acres in the South, from Virginia to Texas. Now, less than 5% of these forests remain due to deforestation by the paper industry, human development, urban sprawl, and fire suppression. The decline of any habitat creates a decline in the species that require the unique characteristics of that environment. The Dusky Gopher Frog needs the ground cover of the forest for protection and food, as well as the temporary wetlands of the forest for breeding.

Another species that, also, lives in the longleaf pine forests is the Gopher Tortoise. The Gopher Tortoise and the Dusky Gopher Frog have a special relationship. The frogs live in the burrows that the Gopher Tortoises create. The destruction of the forest has caused the numbers of Gopher Tortoises to decline. Lower numbers of tortoises mean less burrows for frogs. This lack of shelter is, also, responsible for the decrease in the Dusky Gopher Frog population.

These conditions have been devastating to the Dusky Gopher Frog. Biologists estimate the total Dusky Gopher Frog population to now be less than 250 in the wild. Dusky Gopher Frog Recovery Plan

Because of the endangered status of the Dusky Gopher Frog, the U.S. Fish and Wildlife Service was able to designate nearly 6,500 acres of land in Louisiana, Alabama, and Mississippi as critical habitats for the frogs. This is an important step in saving the remaining longleaf pine forests from further deforestation. There are, also, efforts to restore the longleaf pine forests across its historical range.

Herpetologists from several zoos across the U.S. are doing their part to save the Dusky Gopher Frog. They have collected tadpoles from their remaining breeding ponds and raised them in captivity. These frogs have not been released back into the wild yet. The U.S. Fish and Wildlife Service is still working to identify suitable places for the re-introduction of the frogs and are expected to do so in 2018. Learn More About Dusky Gopher Frogs

Frog Unit Study Pinterest Board Are Endangered Blue Whales Recovering?

Imagine a creature that can grow over 100 feet long, weigh up to 200 tons, and have a heart the size of a Volkswagen Beetle. Sounds like something of myths and legends, doesn't it? Or maybe something prehistoric?

This creature actually exists on Earth right now. The blue whale is the largest animal on Earth. Actually, blue whales are the largest animal to have ever lived. These huge creatures are distributed throughout the world's oceans. However, even with this large expanse of habitat, the blue whale population is very low and they are considered an endangered species.

Let's learn more about the blue whale and why their endangered status is a concern. Blue Whale Facts Where are blue whales found?

As stated before, blue whales are found throughout the world's oceans. In the summer months, they migrate toward the poles to feed and then migrate toward the equator to breed. Blue whales tend to stay in deeper water and avoid coastal areas.

What do blue whales eat?

You might think that the largest animal in the world would be a fierce predator feeding on whatever gets in its way. The truth is blue whales actually have a pretty basic diet of some of the smallest animals in the ocean.

Krill are mainstay of the blue whale diet. These small crustaceans are on average only about 2 inches long. Blue whales filter krill out of large gulps of water at the rate of 8000 tons per day of krill. That's about 40 million krill!

What is the blue whale's life cycle?

Since blue whales are mammals, they give birth to live young one at a time every 2 to 3 years. Newborn blue whales are huge in their own right. They can be up to 25 feet long and weigh up to 3 tons. During the first 8-12 months of life, a baby blue whale will eat nothing but mother's milk and gain 200 pounds a day.

When a baby blue whale can hunt krill on its own, it is weaned and can then make the migration with the adults usually traveling in groups of 2 or 3. Blue whales can live on average 80-90 years. Do blue whales make noise?

Blue whales are among the loudest animals on the planet. A jet engine reaches levels of 140 decibels. The blue whale crushes that with an impressive 188 decibels! Blue whale sounds can be heard up to 1000 miles away. Click HERE to listen to blue whale sounds.

Blue whales are considered endangered animals. Even though their habitat spans all the Earth's oceans, there are an estimated 5-10,000 blue whales in the Southern Hemisphere, and only around 3-4,000 in the Northern Hemisphere according to the American Cetacean Society.

In 1900, a demand for whale oil and whale baleen drove the whaling industry to hunt and kill blue whales by the thousands. Prior to 1900, there was estimated to be 350,000 blue whales. Up to 99% of all Blue Whales were killed by whaling before the International Whaling Commission banned commercial whaling for blue whales in 1966.

Since then, recovery for the blue whale has been slow. New threats to the blue whale have emerged, such as water pollution, habitat destruction, over fishing of krill, and collisions with boats.

Impact Of Blue Whales On The Environment

Nature is a delicate balance with each species in an ecosystem having a very special role. If one species is removed or its populations thrown out of balance (either an profound increase or decrease), all other organisms will be affected. Most of the time, these effects are not good.

Blue whales are at the top of the oceans' food chain. They eat huge amounts of krill each day. If the blue whales disappear, this could cause an increase in the number of krill in the ocean. This overpopulation would mean more competition for the same food supply. This could lead to a drop in the populations of other species.

Whale poop is even important to the oceans' food chain. Phytoplankton need the nutrients in whale poop to thrive. Phytoplankton are an important food source for lots of marine life, such as krill. Phytoplankton, also, plays an important role in removing carbon from our atmosphere - up to 400,000 tons per year. Learn More About Blue Whales

Why Are Tigers Endangered?

The tiger may be the most recognizable of the big cats. Bold, black stripes on an orange background easily set it apart from the lions and panthers. No trip to our local zoo is complete without checking out the tigers. Sadly, these beautiful creatures may only exist in zoos within the next decade.

Subspecies Of Tigers

Tigers are the largest of the big cat species. The scientific name for all tigers is Panthera tigris. However, there are 6 existing subspecies of tiger: Bengal, Siberian, Indochinese, Malayan, South China, and Sumatran tigers. Three other subspecies of tiger have gone extinct in the past hundred years: Balinese, Javan, and Caspian tigers.

All remaining species of tiger are considered endangered. The South China and the Malayan tigers are critcally endangered. There have been no sightings of the South China tigers in several years, so that subspecies may already be extinct. It has been predicted that all tigers may become extinct in the wild within the next decade Why Are Tigers Endangered?

Before the 1900s, tiger populations in the wild were probably over 100,000 animals with 9 subspecies. Now, only 6 subspecies remain and total only 3000 tigers.

Poaching is a large reason why tiger numbers have diminished. In fact, the extinction of the Caspian and the Javan tiger can be directly linked to hunting. Tigers are still being hunted for their fur and other parts of their bodies that are used in traditional medicine.

Tigers are large animals that require a lot of land to roam and hunt. They require tall grasses and vegetation to hide in. Tigers, like all animals, need a good water and food supply. When these are taken away, tigers cannot survive.

Human development and the logging industry have destroyed much of the tiger’s historical habitat. Some research indicates that over 93% of that habitat is now gone. Not only does this take away what tigers need to survive, it has forced tigers to come into more contact with humans. This has led to farmers killing many tigers to protect their livestock.

Tiger Conservation Efforts

Organizations, such as the World Wildlife Fund, is supporting projects to save the tigers from extinction. Efforts are being made to protect current tiger habitats and corridors that link them together. These corridors are important. They allow tigers from different DNA lines to mix and produce more viable offspring. Inbreeding in a small population creates weakened offspring that have a lower chance of survival.

The effort to end tiger poaching has taken on a two-fold approach. First, additional wildlife rangers, monitoring tools, and stricter laws help to stop poaching in the first place. Second, if there is no demand for tigers on the black market, there would be no need for poaching. Shutting down the black market tiger trade is another conservation strategy. Tiger Facts

The tiger is the largest cat in the world. Tigers live throughout Asia from cold, snowy mountain regions to hot rain forests. There are 6 subspecies of tiger thought to still be living. Tigers are carnivores. Tigers can swim and seem to like the water. Tigers can grow up to 11 feet long and over 650 pounds. No two tigers have the same stripe pattern. A group of tigers is called a “streak” or an “ambush”. Tigers hunt alone and at night. Tigers can breed with lions and produce what is called tigons or ligers. Learn More About Tigers

Growing up in a rural area of farms and forests, animals were everywhere – both wild and domestic. It was just part of everyday life to see cows, deer, rabbits, dogs, cats, turkeys, or many other types of animals, including bats. I have always had a love of animals, but the bats fascinate me most of all.

I think it’s the mystery that surrounds them. It’s easy to spot a large cow or deer in a field, or even a quick rabbit in the yard. Bats, on the other hand, are usually only spotted if you are looking for them. It’s hard to see a small, swift, flying creature at night. We used to spot bats flying around our security light in the evening catching the insects the light attracted. Sometimes at dusk, we would see bats flying above the water of the lake getting their fill of mosquitoes.

My dad always saw the need for bats as pest control. He made bat houses and attached them to the sides of our barns and out-buildings. I would watch for movement around the houses in the evening. Seeing them drop out of the house and then take off and fly was an amazing sight. Bat Facts

The mysteriousness of bats drew me to them, but it’s their many other unique characteristics that really set them apart from other animals. Take a look at these bat facts and I think you’ll be amazed by them, too.

Bats are the only mammals capable of actual flight. Bats are nocturnal. Bats are clean animals that regularly clean themselves. There are over 1200 bat species worldwide. Bats make up one fourth of the mammal species on Earth. Bats find food in the dark by echolocation. Bats species have varying diets. Some eat insects. Others eat fruit or nectar, while others eat small animals. Fruit and nectar eating bats are good pollinators. Little brown bats can eat 1000 mosquitoes per hour. There are only 3 species of vampire bats. Over 50% of the U.S. bat population in the US is endangered or in steep decline. Some bats migrate, and others hibernate. Bats can live over 20 years. The largest bat species in the world is the Giant Golden Crowned Flying Fox with weight of 2.5 lbs and a wingspan of over 5 feet! The smallest bat species in the world is Kitti’s Hog-nosed bat weighing 1/4 ounce and is 1 inch long.

Why Are Bat Populations Declining?

Bats are an important part of their ecosystem. They keep insect populations in check and are pollinators of plants. Sadly, in many areas of the U.S. and the rest of the world, bat numbers are in a steep decline. Fifty percent of the U.S. species of bats are endangered. Why?

White-Nose Syndrome

The major threat to bats in the U.S. right now is White-Nose Syndrome . This is a fungus that iskilling hibernating bat species in the United States in huge numbers. It is named for the white fungus that grows on the wings and noses of the bats. This fungus is suspected to be an introduced species and first discovered in cave bats in New York in 2006. By 2016, White-Nose Syndrome spread to more than half of the U.S. states. The fungus irritates the skin of the bats causing them to wake from their hibernation before it is time. This causes the bats to burn through their fat reserves too soon and they starve to death.

Wind Turbines

Another proposed threat to bats is wind turbines. The growing wind energy industry is building an increasing number of turbines across the country. Bats and birds are being injured and killed by the rotating blades. More studies need to be done to give an accurate assessment of the numbers.

Habitat Destruction

When humans destroy natural areas, animal and plant habitat is destroyed. Sometimes species will move into another area. Other times there is no other areas with the proper food and habitat for that species. This causes the decline in population numbers Learn More About Bats
