Scientific Name: Ursus Americanus
Common Name: American Black Bear
The American black bear is native and indigenous to North America. It is found throughout the United States, Canada, and parts of Mexico.
Conservation Status: Common
The American black bear plays a big role in the ecosystem as an omnivore, meaning it eats both plants and animals. It fits in the middle of the food web as it is not exactly at the top, but definitely not at the bottom. These bears eat things like berries, nuts, insects, fish, small mammals, and even carrion, which makes them important scavengers. By eating dead animals, they help clean up the environment, and by spreading seeds through their poop, they actually help forests grow. In terms of trophic level, black bears are secondary or tertiary consumers, depending on what they’re eating at the time. When they are eating berries and plants, they are acting more like primary consumers, but when they hunt small animals or raid beehives, they shift up the chain.
As for threats, black bears aren’t in serious danger overall, but that doesn’t mean life is easy for them. Some of the biggest challenges they face come from habitat loss, vehicle collisions, and conflicts with humans (like getting into garbage, which can sometimes lead to them being relocated or killed). Hunting is also a factor in certain areas. With that said, they are super adaptable, which is why they are still thriving across North America.

BOBCAT
(Lynx Rufus)
Bobcats are the only native wild cat in Indiana, they are however common in
Southern and parts of central Indiana. However, they are increasing in Northern
Indiana. Bobcats are considered rare because of their ability to blend into
surroundings and move quietly.
Environment: They tend to be in areas like forests, grasslands, swamps,
deserts, and shrublands. (Their vocalizations are never heard by people)
Ecosystem: Bobcats are strictly carnivores, they are the secondary
consumers.They control the populations of other animals, and are essential
members of North American ecosystems. (Their diet consists largely of rabbits
and small to medium-sized rodents.They also eat birds and bird eggs, bats, deer,
insects, reptiles, fish, and carrion.)
Major Threats: The bobcat is a species of special concern in Indiana.
(Including:habitat loss and unregulated hunting and trapping.They were listed as
endangered in 1969, but were removed from the endangered list in 2005)
Life Span: Up to 15.5 years in the wild, 32 years in captivity (The oldest wild
bobcat on record was 16 years old, and the oldest captive bobcat lived to be 32.)
Reproduction: Bobcats are territorial and generally solitary animals. While
bobcats can breed year-round, the vast majority of mating generally occurs
in early spring during February and March with the young being born after a
62-day gestation period. (Litters of kittens range from 1-3)
Behavior: Bobcats are solitary and nocturnal but can be seen occasionally
during the day. They use hidden dens, typically hollow trees and rock piles,
but also thickets and brush piles. Bobcats often rest near fresh kills. Prey is
attacked by either stalking or ambush.(Bobcats communicate using
scent-marking and a variety of vocalizations including caterwauling, growls, and hisses.)
Appearance: Bobcats are the smallest wild cats in North America,
however they are about two to three times larger than typical house cats.
The fur is yellowish to reddish brown with black-tipped guard hairs along
the sides. The belly is white with numerous, irregular, black spots. The front
legs are tan and contain horizontal black bars on the inside. Bobcats have
tufts of hair on the cheeks.The ears are marked with large, white spots
and are erect. Each ear has a tuft of hair at the tip. The tail is
short with several dark bars. (Short tail typically less than 6 inches long that is
white on bottom and black-striped on top.)
FUN FACTS: Despite its striking resemblance to the household cat, the
bobcat is a fierce predator. (Estimated about 1,000 bobcats in Indiana

Common name: Raccoon
Scientific name: Procyon lotor
Raccoons are native to North America and can be found in the majority of the United States. They will also be found in Canada, Mexico, and parts of South America.
Cosmopolitan, Indigenous to North America
Conservation status: Least Concerned; not endangered
Raccoons are omnivores and are considered secondary consumers because they can be both predators and prey. Raccoons are considered scavengers and will feed on just about anything. They are notorious for rifling through trash cans at night in search of food. Scavengers are important to ecosystems because they clean up dead animals that have been discarded by other predators. They are predators to grubs wasp larvae, rodents, and small snakes. Raccoons are partly responsible for keeping those species populations in order. Another positive that raccoons bring to the environment is bee protection by preying on wasps. While raccoons are predators to these mentioned species, they are prey to other larger species. Coyotes, foxes, bobcats, great horned owls, and wolves are all among the species that prey on raccoons. There are not many major threats to the survival of raccoons, but one concern is human-caused issues. Raccoons are often victims of road kill and are frequently hunted. Raccoons can also be susceptible to diseases like rabies. However, neither of these threats actually threatens the species as a whole as raccoons are adaptable in their environments and have been able to maintain their population.
Raccoons are nocturnal animals who do most of their feeding and scavenging at night. Raccoons are considered to be highly intelligent animals. A study that was conducted in the mid-to-late-twentieth century found that they were able to remember solutions to tasks for up to 3 years. In the wild raccoons often live 1 to 3 years. However, when they live in captivity where they don’t need to worry about finding food themselves they can live up to 20 years. However, it is not recommended to keep raccoons as pets due to their unpredictability from being undomesticated.
• The red fox, known for its vibrant coat and cunning nature, is scientifically classified under the name Vulpes vulpes Linn.
• The red fox (Vulpes vulpes), a fascinating species renowned for its distinctive reddish fur and bushy tail, is believed to be a non-native inhabitant of Indiana, as historical records point towards their introduction to much of the United States from Europe. This introduction paved the way for their expansive presence across the country, with red foxes likely finding their way into the Indiana landscape alongside European settlers, a migration potentially taking place during the mid-1800s. The red fox's adaptability and resourcefulness enabled them to thrive in various environments, including the diverse habitats found in Indiana, where they have established themselves over the years.
• In the IUCN Red List, red foxes are generally categorized as a species of least concern due to their widespread distribution and healthy population levels across various regions. However, certain localized populations face different conservation statuses, highlighting the need for specific conservation efforts in these regions. For instance, in Mongolia, red foxes are categorized as near threatened, indicating factors such as habitat loss or human-wildlife conflict that threaten these particular populations. On the other hand, in Korea, red foxes are sadly considered extinct due to historical and contemporary factors that have led to the disappearance of these once-thriving animals from the local ecosystem.
• The red fox is a very important predator that actively hunts and consumes prey animals like rodents and rabbits, thus controlling their populations. It also aids in seed dispersal by consuming fruits and then spreading seeds. In areas where foxes have been eradicated, farmers import new ones to restore the population. Being an omnivore, the red fox preys on both plants and herbivorous animals hence this occupant holds an important slot in the food chain. Its diet includes small rodents, squirrels, woodchucks, rabbits, birds, eggs, amphibians, reptiles, vegetation, fruits, nuts, insects, carrion, and garbage.
• Red foxes are a significant predator and invader, affecting ecosystems, species, economies, and cultures across vast regions. Their impact includes livestock loss for farmers and species extirpation. Most red foxes are young pups, and they may be attacked by coyotes, wolves, or other predators, but rarely for food. Humans are the most important predators on red foxes, and they may also be attacked by these predators.

Common Name: Beaver
The beaver is indigenous to North America, meaning it naturally occurs in this region and has adapted to its environment over time. The North American beaver is neither endangered nor threatened. In fact, the population of beavers is considered stable and common across their native range in North America.
The beaver has a few roles in the ecosystem, including “ecosystem engineers” due to their dam-building activities which create wetlands, ponds, and marshes. These habitats support biodiversity. The dams which beavers build help regulate water flow, reducing the risk of floods and maintaining water levels. They also improve water quality by trapping pollution. By cutting down trees and shrubs for food and habitation, beavers promote new plant growth and create open areas in forests, which leads to greater plant diversity.
Beavers are primary consumers in the food web. They feed on plants such as bark, leaves, twigs, and aquatic vegetation, which are producers and are preyed upon by higher-trophic-level predators.
By creating wetland habitats, beavers support various species of fish, birds, amphibians, and insects. Beaver dams help to slow down the water flow and reduce soil erosion, which in return allows for the benefit of the landscape and downstream ecosystems. The ponds and wetlands created by beavers act as a natural filter.
Beaver dams can sometimes cause unintended flooding of agricultural lands, roads, and settlements, leading to conflicts with humans. Their feeding and building can damage forests and reduce the availability of certain tree species.
Human activities such as urban development and agriculture can lead to the destruction of beaver habitats. This reduces their ability to maintain their populations. Water pollution can also pose a threat to the survival of the beaver species. Natural predators such as wolves, bears, and large birds of prey can pose a threat to beaver populations. Additionally, human hunting and trapping can also impact their populations.

Common Name: Hedgehog
Scientific Name: Erinaceinae
The species Hedgehog is Native to certain regions. For example, the European Hedgehog is native to Europe and the African Pygmy Hedgehog is native to Africa. Areas where hedgehogs are non-native are around places like New Zealand. Hedgehogs are considered an ecological threat in New Zealand because the prey on native animal egg of ground-nesting birds. Some types of hedgehogs are considered Indigenous like the Southeast Asian hedgehog which is indigenous to certain parts of Asia. In all hedgehogs are typically native to Europe, Asia, and Africa.
In general hedgehogs are common in places like Africa and Asia. Although in Europe the European hedgehog is the biggest species of hedgehog is endangered and threatened because of the different environmental pressures. Here have been efforts in various places to protect them and finding safe places for them and reducing road mortality.
The role of the hedgehog in the food web are important. They are considered omnivores foragers who mostly feed off of insects, worms, small vertebrates and sometimes fungi. The trophic level of the hedgehog is considered a secondary consumers, they feed off of herbivores. Sometimes they eat plants which make them omnivores, but they mostly eat insects. The hedgehog special ecological role includes pest control which means they eat insects and help the number of insects and help balance the population. They also help control the spread of parasites which includes ticks. Hedgehogs are not considered to be decomposers but can help with the nocturnal and soil health. They burrow into the ground and search for food that way and disturb the soil which could be beneficial effects on the soil aeration and nutrient cycle.
The threats of the hedgehog happen when cities expand their living and the places where hedgehogs naturally live like grasslands and woodlands are destroyed and fragmented. Because of this it limits the places available for them to live and to nest and travel safely. The draining of wetlands reduce the amount of land for hedgehogs to live and also makes it difficult for the number of insect population which are the reliable source of food for hedgehogs. There is also a problem with climate change. Hedgehogs cannot live in sensitive weather conditions like heavy rain or cold winters, and it can cause them to attract hypothermia and dehydration. Climate change can make it difficult for them to hibernate and they cannot adapt.
An interesting fact about hedgehogs is that their spines are not bones like human spines but more like modified hairs that are made of keratin. Keratin is also what human hair and nails are made out of. This causes the hedgehog to have about 5,000 to 7,000 spines which protects them from predators.
White-tailed Deer by Morgan Fogle

Scientific Name: Odocoileus virginianus
Common Name: White-tailed Deer
Native to Indiana
Conservation status: Common
The white-tailed deer is known to be an herbivore that mainly feeds on different types of grasses, acorns and other fruits in the fall, mushrooms in late summer or fall, and farm crops that are planted in the agricultural regions of the United States. They can be responsible for cutting a ring around a tree’s trunk (girdling), which can result in the tree dying. White-tailed deer also have an impact on the composition of plant life in areas where they are abundant. The population of white-tailed deer is robust. There is no concern for their population, even though they are hunted by several predators. This may be due to the fact that the male deer may mate with several females.
There are numerous predators of the white-tailed deer. These include humans, grey wolves, mountain lions, coyotes, bears, and jaguars. They are hunted by humans for both sport and meat. However, if the population of the white-tailed deer becomes too high, it can lead to overgrazing. This can cause a depletion in forest vegetation. They are also an example of sexual dimorphism. This is the idea that males and females of the same species look different. Males have antlers (ornamentation) and are larger than the females. Females are smaller in size and do not have antlers. White-tailed deer will rely on smell to detect predators. They are agile, and they will run from the danger with their tail in the air. These animals are great swimmers and may be able to run at speeds close to thirty miles per hour.
