2. Biodiversity Register
Kaushal Bodh, Class 6 — observing and recording the living things around us
You will learn
  • What biodiversity is and why we must record it
  • Key terms used in a biodiversity register
  • Planning surveys and filling the register tables
  • Using experts and AI tools, presenting findings, and India's Biodiversity Heritage Sites

1Biodiversity and the register

Biodiversity is the variety of life forms on earth: plants, animals, birds, fish, insects and even microorganisms found everywhere, including soil. A biodiversity register documents the living things of an area: the habitat (landscape and soil), scientific and local names, what animals eat, living things that may harm others, and more.

Recording biodiversity is crucial. Habitats change through land clearance for construction or farming and shifts in climate, so many species face extinction or become endangered. Because living things are interconnected, the loss of any species affects ecosystems, including humans. Registers also preserve useful knowledge on crops, animals, medicinal plants, pests and planting times.

For an unfamiliar living thing, ask teachers, elders or experts, use library books, search the Internet, or use mobile apps.

2Terms used in the register

TermMeaning
Scientific nameSame across languages, so everyone refers to the same living thing
VarietyDifferences within a similar plant, e.g. mangoes Alphonso, Kesar, Totapuri, Dasheri, Langra
Cropping seasonSeason in which a crop is grown
Season of fruitingWhen fruit trees bear fruit
Source of seeds/plantsHow new plants grow: seeds, seedlings, bulbs, stem cuttings
Affected cropA crop damaged by pests, diseases or other reasons
HostA plant or animal on which others live, e.g. dogs for fleas
PestsInsects, birds or animals harmful to plants
PesticidePrevents harm by pests; liquid, solid or gas
WeedicidePrevents harm to plants by weeds
GI tagGeographical Indication: grown in a specific region, high-standard produce, e.g. Navara rice (Kerala), Basmati (Uttarakhand), Gobind Bhog (West Bengal), Jalgaon bananas
Remember
Alphonso mangoes have a GI tag for their origin in Ratnagiri and Sindhudurg, Maharashtra.

3Getting ready: materials, safety and experts

You need a notebook, pen, eraser, scale and sharpener; a magnifying glass for details; and a borrowed camera or smartphone for photos, videos, audio and identification. Even with photos, you must make sketches of everything in the register.

  • Wear shoes; cover arms and legs against mosquitoes.
  • Observe wild plants and animals carefully; do not disturb any animal, bird or insect.
  • Do not damage any plant or leave garbage behind.
  • Use the Internet only with the teacher's help and never share personal information.

In Activity 1, note familiar living things, their names in many languages and where they are found; each plant supports a tiny cosmos of insects, spiders, squirrels and birds. In Activity 2, invite experts such as a forest officer, farmer, conservationist or a Vaid/Vaidya (traditional medicine expert) with prepared questions.

The sequence of activities in the project

Choose places you can reach quickly: around school, water bodies, home, farms, parks, nurseries, religious places and markets. Work in groups of at most 5, consult local experts and schedule visits at different times of the year to see seasonal change. Carry binoculars, a magnifying lens, a camera, field guides and a notebook.

For each visit, note the date, location, habitat type and weather. Share observations, add new information on every visit, sketch or photograph unfamiliar living things, and speak to the teacher before leaving any part blank.

PestAphid on potatoAloo (Hindi) for potatoMyzus persicae, Aphis gossypii; potato Solanum tuberosumUnder leaves; winged or wingless; attacks after winter

5Identifying 'unknowns' with experts and AI

Missing information can come from experts, community members, the library or AI tools. Google Lens is an image recognition technology using machine learning and OCR (Optical Character Recognition). It identifies objects, reads text, translates languages and scans barcodes and QR codes. Open the app, tap the Lens icon in the search bar, point the camera and tap the shutter button.

The Season Watch website lets you register a tree near you and upload photographs every week.

Exam tip
Know the full form OCR = Optical Character Recognition and the three steps for using Google Lens.

6Presenting your register

The presentation is based only on your own observations and information, using charts, diagrams or models.

Part 1: Summary for a visitorPart 2: Going beyond
Which plants grow around you; which are seasonalWere there more living things in one place than another?
Are crops and fruits harvested in the same season? Do all plants flower together?How many varieties of plants and pests did you see?
Is fodder available all year?Did the same insects appear in several places?
Are plants affected by weeds and pests? Are some weeds useful?Which AI tools or other sources did you use?
What did the community share (medicinal, fodder, sacred plants)?Your conclusion or reflection

Also ask experts what measures can preserve local biodiversity, and ask community members how biodiversity has changed over the last 10 or 20 years.

7Biodiversity Heritage Sites and urban wildlife

Biodiversity Heritage Sites are areas recognised for unique biodiversity, protected to conserve it and respect traditional cultural practices linked to nature.

SiteWhat is special
Nallur Tamarind Grove, KarnatakaTamarind trees over 400 years old
Gogabeel, BiharOver 90 bird species, some from Central Asia
Tonglu, West BengalPlants found nowhere else
Ameenpur Lake, HyderabadOver 200 bird species in a busy city
Majuli, AssamBiggest river island; monasteries called Satras
Myristica swamps, KeralaAncient nutmeg (Jayafala) trees
Kali Tiger Reserve, KarnatakaBengal tigers and elephants
Chilkigarh Kanak Durga Sacred Grove, West BengalMedicinal plants, protected by local people
Ziro Valley, Arunachal PradeshRice and fish grown together
Mawphlang Sacred Grove, MeghalayaRare plants and medicinal herbs, protected by tribes

Birds like kites and animals like mongooses living in cities are called urban wildlife. Students can keep a nature journal or digital scrapbook, observe birds visiting home, and ask elders which birds and animals they saw when young. Related jobs: forest officer, scientist and conservationist.

Common mistake
Mixing up Majuli (biggest river island, Assam) with the Myristica swamps (nutmeg trees, Kerala), or Gogabeel (Bihar, 90+ birds) with Ameenpur Lake (Hyderabad, 200+ birds).

In short
  • Biodiversity is the variety of life on earth, from large animals to soil microorganisms.
  • A biodiversity register documents living things, habitats, names and interactions in an area.
  • Recording matters because habitat change can endanger species, and all life is interconnected.
  • Plan surveys in small groups at different seasons; note date, location, habitat and weather.
  • Fill tables for crops, fruits, fodder, weeds and pests; sketch everything and share observations.
  • Use experts, the library and AI tools like Google Lens to fill gaps, then present your findings.
  • India's Biodiversity Heritage Sites protect unique biodiversity and traditional practices.
