It is broader than the term flora which refers exclusively to species composition. Perhaps the closest synonym is plant community, but vegetation can, and often does, refer to a wider range of spatial scales than that term does, including scales as large as the global. Slide 3: Primeval redwood forests, coastal mangrove stands, sphagnum bogs, desert soil crusts, roadside weed patches, wheat fields, cultivated gardens and lawns; all are encompassed by the term vegetation Importance : Importance Vegetation supports critical functions in the biosphere, at all possible spatial scales. First, vegetation regulates the flow of numerous biogeochemical cycles (see biogeochemistry), most critically those of water, carbon, and nitrogen; it is also of great importance in local and global energy balances. Such cycles are important not only for global patterns of vegetation but also for those of climate. Slide 5: Perhaps most importantly, and often overlooked, global vegetation (including algal communities) has been the primary source of oxygen in the atmosphere, enabling the aerobic metabolism systems to evolve and persist WILDLIFE : WILDLIFE Wildlife includes all non-domesticated plants, animals and other organisms. Domesticating wild plant and animal species for human benefit has occurred many times all over the planet, and has a major impact on the environment, both positive and negative. Slide 7: Wildlife can be found in all ecosystems. Deserts, rain forests, plains, and other areas including the most developed urban sites All have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that wildlife around the world is impacted by human activities. Slide 8: Humans have historically tended to separate civilization from wildlife in a number of ways including the legal, social, and moral sense. This has been a reason for debate throughout recorded history. Religions have often declared certain animals to be sacred, and in modern times concern for the natural environment has provoked activists to protest the exploitation of wildlife for human benefit or entertainment. Literature has also made use of the traditional human separation from wildlife Slide 9: Anthropologists believe that the Stone Age peoples and hunter-gatherers relied on wildlife, both plant and animal, for their food. In fact, some species may have been hunted to extinction by early human hunters. Today, hunting, fishing, or gathering wildlife is still a significant food source in some parts of the world. In other areas, hunting and non-commercial fishing are mainly seen as a sport or recreation, with the edible meat as mostly a side benefit. Food,pets ,traditional medicines Religion : Religion Many wildlife species have spiritual significance in different cultures around the world, and they and their products may be used as sacred objects in religious rituals. For example,eagles, hawks and their feathers have great cultural and spiritual value to Native Americans as religious objects Destruction : Destruction Exploitation of wild populations has been a characteristic of modern man since our exodus from Africa 130,000 – 70,000 years ago. The rate of extinctions of entire species of plants and animals across the planet has been so high in the last few hundred years it is widely considered that we are in the sixth great extinction event on this planet; the Holocene Mass Extinction. Overkill : Overkill Overkill occurs whenever hunting occurs at rates greater than the reproductive capacity of the population is being exploited. The effects of this are often noticed much more dramatically in slow growing populations such as many larger species of fish. Initially when a portion of a wild population is hunted, an increased availability of resources (food, etc) is experienced increasing growth and reproduction as Density dependent inhibition is lowered. Habitat destruction and fragmentation : Habitat destruction and fragmentation The habitat of any given species is considered its preferred area or territory. Many processes associated human habitation of an area cause loss of this area and the decrease the carrying capacity of the land for that species. In many cases these changes in land use cause a patchy break-up of the wild landscape. Agricultural land frequently displays this type of extremely fragmented, or relictual, habitat Slide 14: BY- HARDIK VASHISHT X-B You do not have the permission to view this presentation.
