5. Species diversity- Quadrats & Transects
A transect line is any line, marked at regular intervals,
that is easy to use in the field.
Transect lines can be purchased commercially, made
from measuring tape or rope marked off at regular
intervals.
A quadrat is a framed area.
6. Level of Endemism:
Endemism is the ecological state of a species being
unique to a defined geographic location, such as an
island, nation, country or other defined zone, or
habitat type; organisms that are indigenous to a place
are not
For example: Endemic species, such as the lemurs of
Madagascar .
7. Simpsons Intex
Simpson's Diversity Index is a measure of diversity
which takes into account the number of species
present, as well as the relative abundance of each
species. As species richness and evenness increase, so
diversity increases.
n = the total number of organisms of a particular
species
N = the total number of organisms of all species
8. Shannon-Wiener index:
Shannon–Wiener index of diversity (information
index) A measure used by ecologists when a system
contains too many individuals for each to be identified
and examined
9. GIS:
A geographic information system (GIS) is a system
designed to capture, store, manipulate, analyze,
manage, and present spatial or geographic data.
10. GIS Application:
Crop mapping yield estimation
Crop assessment and Crop health
Irrigated landscape mapping
Application development for GIS agriculture
Soil and irrigation amendment analysis
Suitability assessment studies
Erosion identification and remediation
Agricultural mapping for detailed vegetation cover and
monitoring
Change detection studies and developing crop models
Damage and land degradation assessment studies
Elevation models for efficient drainage
