Chadron High's Wildlife Science students recently completed a unit on endangered species from around the world. They created a model of the animal and its habitat. Students researched and compiled data. Requirements for the project included: Identification by Genus and species, common name, geographical location-map, current population graph, causes of endangerment, patterns or trends relating to the population, physical description of animal, food sources, track comparison, migration patterns, breeding characteristics, gestation, life span, unique characteristics, symbiotic relationships, recovery efforts, future outlook, and organizations associated with species. All documented information was organized into a visual graphic poster design.
Students orally presented to their peers and then shared what they had learned with fourth grade at the Intermediate building. The high school students used IPADs to show the animal's behavior in addition to the physical models and verbal explanations. Animal topics included: Amur Leopard, Clouded Leopard, Whooping Crane, Bengal Tiger, Green Sea Turtle, Mountain Gorilla, Giant Panda, Black Rhino, Caspian Seal, Orangutan, Chimpanzee, and Zebra. Students from both buildings stated it was a positive learning experience and would like it to continue. It tied in nicely, as the fourth graders were conducting research on an endangered species as well!
A great time was had by all participants!

Man's desire to expand rapidly has destroyed the natural habitat of wild animals, making them homeless. of Nature (IUCN) includes the red list names of over 5,000 vertebrate animals, among a total of 15,589 species, as .
- The main reason for animals endangered is the uncontrolled human activity. To pursue mindless development, man has created irreparable damages. The gases emitted from greenhouses have brought global affecting everybody. Industrial wastes have polluted the river water and marine life.
- Overexploitation of animals to satisfy the needs of humans has led to considerable downfall in their number. Unrestricted hunting of Whales during the twentieth-century has made them endangered animals. Poaching of rhinoceros and tigers is another serious cause of their falling numbers. Rhino horns and are widely used in making traditional medicines.
- It is important to save the endangered animals to maintain the ecological balance. Nature has its own way of maintaining the balance. If we do not take steps to ensure it, we will ultimately have to face the consequences.

Several species have moved down the threat categories or been removed from the Red
List altogether. Examples include the Chinese Crested Ibis, Mauritius Kestrel, Hawaiian
Goose, White Rhino, and Short-tailed Albatross.
Following large recoveries in many European countries, the numbers of White-tailed
Eagles (Haliaeetus albicilla) doubled in the 1990s and the species has been downlisted
from Near Threatened to Least Concern. Enforcement of legislation to protect the species,
and measures to address threats from habitat changes and pollution contributed to the
Biological diversity - “biodiversity” means the diversity of life on Earth, including terrestrial,
marine and other aquatic ecosystems and the ecological complexes of which they are
part; this includes diversity within species, between species and of ecosystems.
Biome: major ecological community, a division of the world’s vegetation that corresponds
to a particular climate and is characterized by certain types of plants and animals, for
example, tropical rain forest or desert.
Ecosystem: a dynamic complex of plant, animal and micro-organism communities and
their non-living environment interacting as a functional unit.
Endemic: restricted to a particular area: used to describe a species or organism that is
confined to a particular geographical region, for example, an island or river basin.
Genus: set of closely related species: a category in the taxonomic
classification of related organisms, comprising one or more species. Similar genera
grouped in families.
Habitat: the place or type of site where an organism or population naturally occurs.
Invasive alien species: are those that occur outside their natural range and threaten the
existence of native plants and animals.
Taxon: category of organisms, any of the groups to which organisms are assigned
according to the principles of taxonomy, including species, genus, family, order, class, and
