National park is a recreation center being used for preservation purposes, made and secured by national governments. Regularly it is a hold of common, semi-normal, or created land that a sovereign state announces or claims. Albeit singular countries assign their own national stops in an unexpected way, there is a typical thought: the preservation of 'wild nature' for successors and as an image of national pride. A global association, the International Union for Conservation of Nature (IUCN), and its World Commission on Protected Areas (WCPA), has characterized "National Park" as its Category II kind of secured areas. According to the IUCN, 6,555 national parks overall met its measures in 2006. IUCN is as yet talking about the boundaries of characterizing a national park. National parks are having a lot of importance in these days, as they are protecting the animals to be hunted down by people. In national park, the animals and birds are kept like as they are in the forest but with protection. High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
