Graduation Ceremony

20. • To be able to define population density and
methods used to estimate it
• To be able to sketch each of the three major
dispersion patterns and identify the distribution of a
population based on their dispersion pattern.
• To understand the diversity of Indian National Parks.
• To construct a Red data Book.
• To be able to appreciate diversity in communities.

22. Density and Dispersion
• Density
Is the number of individuals per unit area or
volume
• Dispersion
Is the pattern of spacing among individuals
within the boundaries of the population

23. • Environmental and social factors influence the spacing of individuals
in a population
1. Clumped dispersion
In a clumped dispersion, individuals are clustered in groups
2. Uniform dispersion
In a uniform dispersion, individuals of a population are spaced more or
less evenly.
3. Random dispersion
In random dispersion, individuals are distributed randomly, without a
predictable pattern.

24. Clumped dispersion

25. Uniform dispersion

26. Randomly distributed ferns

27. National Parks of INDIA

28. National Park
An area of scenic beauty, historical importance, etc. owned and maintained by a national
government.
National parks in India are IUCN category II protected areas.
India's first national park was established in 1936 as Hailey National Park, now known as Jim
Corbett National Park. By 1970, India only had five national parks.
As of April 2012, there were 102 national parks. All national park lands then
encompassed a total 39,919 km2 (15,413 sq. mi) km², comprising 1.21% of India's
total surface area.
There are over 100 national parks and 500 wildlife sanctuaries in India, which reflect
the importance that the country places on nature and wildlife conservation

30. Corbett National Park
Established in 1936, Corbett National Park is India's first Eco Park , located in
the state of Uttarakhand.
Spanning across the span of 920.9 square km, Corbett National Park is India's
most popular national park.
It is the home to 50 mammal species, 110 tree species, 25 reptile species and 580
bird species.
It is also a Tiger Reserve Project of the country preserving the endangered Bengal
Tiger.
This oldest park in the country is considered as the perfect adventurous
destination.

31. Sunderbans
Located in the state of West Bengal, and Created in 1973, the core area
of Sunderban was declared a National Park in 1984.
It was declared a Biosphere Reserve and a UNESCO World Heritage
site.
Sunderbans has amazing river bodies as well as forest areas. Bengal
tigers, crocodiles and snakes are some creatures you can spot here.
It is one only one of its kind in the world. It is spread over more than 50
islands and extends into neighboring country of Bangladesh.

32. Kaziranga National Park
Located in the state of Assam, it is a famous wildlife park of India. It is also a
UNESCO World Heritage Natural Site.
Kaziranga covers an area of 378 km2 (146 sq mi), with approximately
51.14 km2 (20 sq mi) lost to erosion in recent years.
It cherishes its population of one horned rhinoceros, though its also a Tiger
Reserve. It can also be applauded for water buffaloes, elephants and other
animals.
Crisscrossed by four major rivers, including the Brahmaputra, and the park
includes numerous small bodies of water.

40. Populations rarely, if ever, live in isolation from populations
of other species. In most cases, numerous species share a
habitat. The interactions between these populations play a
major role in regulating population growth and abundance.
All populations occupying the same habitat form a
community: populations inhabiting a specific area at the
same time. The number of species occupying the same
habitat and their relative abundance is known as species
diversity.

46. Thank
You!!
