rich medicinal plant heritage.
A variety of medicinal plants are found primarily in forests, while some are also cultivated.
Conservation is the process of managing the biosphere in order to increase its benefit to the current generation while preserving the potential for future generations.
Conservation of Plant resource is a global concern since we are unaware of what we're losing or what we'll need in the future.
Many medicinal plants are threatened by various primary and secondary factors. Habitat loss due to increasing human activity, forest decline, spread of alien species, destructive collection of plant species, industrialization, over exploitation, changes in agricultural practices, excessive use of agrochemicals, natural and manmade calamities, genetic erosion etc., are threats to medicinal plants.
In India, an extensive amount of medicinal plants are extracted out of the wild to fulfil the rising demand of raw materials for both domestic and international trade. The effect is that the natural resources are quickly running out.
Medicinal plants promote livelihood security, farming, cultural identity, and health. Therefore, the germplasm needs to be conserved, grown and maintained for future use.

Biodiversity and its Conservation methodsNishat Fatima
Biodiversity describes the richness and variety of life on earth. It is the most complex and important feature of our planet. Without biodiversity, life would not sustain.
Biodiversity holds ecological and economic significance. It provides us with nourishment, housing, fuel, clothing and several other resources. It also extracts monetary benefits through tourism. Therefore, it is very important to have a good knowledge of biodiversity for a sustainable livelihood.
Demand and Supply Situation for Medicinal PlantsAI Publications
From 2020 to 2015, it was predicted that the demand for medicinal plants in India will increase at an annual pace of between 17 and 23 percent to meet the needs of both domestic and international consumers. Small-scale farmers stand to gain financially and economically from a well-organized medicinal plant production and administration system. Ayurveda, Unani, and Siddha are the three main Indian medical traditions, and together they are expected to bring in more than $500 million annually. In 2015, the gap between demand and supply of MAPs was predicted to be between 50,000 and 250,000 tons. In 2020, this hole was predicted to grow from 250,000 to 500,000 metric tons. Modified accelerated production (MAP) industries provide labor opportunities in economically depressed states, raising the standard of living and tax base of the area.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

• Medicinal plants play an important role in the health care system of
most developing countries.
• They are the most important source of life saving drugs and are best
resources of novel drugs.
• Approximately one quarter of prescribed drugs contain plant
extracts or active ingredients obtained from plant substances.
• Many of the modern medicines are also produced indirectly from
medicinal plants.
• The traditional health care practice is mainly dependent on
medicinal plants collected from the wild.

11. Conservation Status of Medicinal Plants in India
• 350 medicinal plant species have already been assessed (in 18 States) as
„Red-Listed‟ in India
• In South India alone, it is estimated that about 70-80 out of the estimated
300 medicinal plants are either endangered or threatened.
• 100 of these „Red-Listed‟ species are in active trade (36 „CR‟ species and 67
„EN‟ species)
• Wild populations of many of these species are fast reaching a level of „No
Return‟
• Industry forced to use „substitutes‟ (?) that may be less efficacious
• Rural people losing all-important „Cash Income‟
Hence, there is a necessity to strike a balance between conservation and
utilization of these medicinal plants.

13. CONSERVATION: Meaning
• „CONSERVATION‟ term in general means protection of species and
natural resources, globally.
• Conservation is the process of management of biosphere in order to obtain
the greatest benefit for the present generation and maintaining the potential
for future.
• It is the wise use of natural resources,withoutwastingthem.
• India has one of the richest plant medical cultures in the world. Medicinal
plants that have been used by Ayurveda, Sidda, Unani &Tibetan system of
health care face an uncertain future due to over exploitation. Conservation
is about preventing damage and loss to our cultural heritage.

14. Need for Conservation of Medicinal Plants
Preparedforacademic purpose only 14
“Conservation of plant resources is of global concern because we don't
know what we are losingand what we will need in future.”
To meet the requirements of expanding regional and international
markets, healthcare products and needs of growing populations, large
quantitiesof medicinal plants are harvested fromforests.
In India large number of medicinal plants are extracted from the wild to
meet the increasing demand for raw material needed for domestic
consumption and for export. As a result, the natural sources are rapidly
depleting.
Hence, there is a need for conservation, cultivation, maintenance and
assessmentof germplasmfor futureuse.
15. Goal of Conservation of Medicinal Plants
Preparedforacademic purpose only 15
To support sustainable development of medicinal plants by protecting and
using them in ways that do not diminish the world’s variety of genes and
species or destroy important habitats and ecosystems.
To safeguard species that are threatened or endangered of their existence.
Conservation of biological diversity involves protecting, restoration and
enhancing the variety of life in an area so that the abundance and
distribution of species and communities contributes to sustainable
development.
To maintain the evolutionary potential of species by maintaining natural
levels of diversity which is essential for the maintenance of genetic
variation is essential for long-term protection of a taxon.

19. IN SITU CONSERVATION
Preparedforacademic purpose only 19
In-situ conservation deals with the ‘on-site conservation’ of the wild
genetic resources/genetic diversity in their natural habitats i.e.,
within the ecosystem to which it is adapted.
Thus in situ conservation refers protecting the medicinally
endangered plant species in protection zones and areas of high
biologicaldiversity, e.g. Forests, etc.
20. IN SITU CONSERVATION
Preparedforacademic purpose only 20
The key operational steps for establishing in situ methods for conservation of
prioritized medicinal plants include:
Threat assessment, establishment of a network of medicinal plant forest reserves,
involving local stakeholders, botanical, ecological, trade and ethno-medical surveys,
assessing intra-specific variability of prioritized species, designing species recovery
programmes, etc.
Conclusively, no in situ conservation project can succeed without the complete
cooperation and involvement of local people.

Medicinal Plants Conservation Areas (MPCAs)
Preparedforacademic purpose only 39
• Conservation of medicinal plants in their natural habitats is important as
it is the most cost-effective way of maintaining their gene pools while
retainingtheir full natural evolutionary potential.
• Most of the medicinal plants are confined to certain habitats with a
restricted geographic range.
• Their rarity coupled with large scale destructive collection from the wild
has resulted in conservation efforts being initiated by governmental
(National Medicinal Plant Board, NMPB; State Medicinal Plant Board,
SMPB) and nongovernmental agencies (NGO’s) focused on their
conservation and sustainable use.
45. EX SITU CONSERVATION
Preparedforacademic purpose only 45
EX SITU CONSERVATION is defined as protecting the endangered species
outside their natural habitat, in the form of whole plants, seed, pollen,
vegetativepropagules,genesor DNA, tissues or cell cultures,etc.
It is an "off-site conservation” involving the process of protecting an
endangered species of plant by removing part of the population from a
threatened habitat and placing it in a new location, which may be a
wildarea or withinthe care of humans.
While ex-situ conservation comprises some of the oldest, natural and
best known conservation methods, it also involves newer laboratory
methods.
46. Preparedforacademic purpose only

When to do Ex situ conservation?
This measure is to be adopted when the numbers of a species have
declined so massively that individuals need to be rescued and given
refuge elsewhere.
Purpose:
Rescue threatened species of plants and animals.
Produce material for reintroduction, reinforcement, habitat
restoration and management.
Supply material for various purpose including research
Remove or reduce pressure from wild collecting
Make available material for conservation education and display.
48. Preparedforacademic purpose only 48
Botanical gardens are the most conventional methods of ex-situ
conservation, which house whole plants, protected specimens for
breeding and reintroduction into the wild when necessary and
possible.
These facilities provide not only housing and care for specimens of
endangered species,but also have an educationalvalue.
They inform the public of the threatened status of endangered
species and of those factors which cause the threat, with the hope of
creating public interest in stopping and reversing those factors which
jeopardize a species’ survival in the first place.

On farm conservation involves the maintenance of traditional crop
cultivars (land races) by farmers within traditional agricultural
system.
It is based on the recognition that farmers have improved and
grown genetic diversity.
Farmers should be encouraged to continue their land races by
agricultural development policies that enhance incentives to
continueto maintain land races.
62. EX SITU CONSERVATION:On Farm Conservation
Preparedforacademic purpose only 62
Given the role of farmers on farm conservation, meeting
development goals such as increased farm income is critical.
In a recent conclusion study by NBPGR with IRRI, Philippines and
GKV, Raipur in Baster area of MP suggested that on farm
conservation of rice genetic resources is a compliment to ex-situ
conservation in tribal area of Baster Plateau which can be
motivated for maintaining crop diversity provided it is a viable
option.

techniques.
66. EX SITU CONSERVATION: Field Gene Banks
Preparedforacademic purpose only 66
The conservation of germplasm in field gene banks involve: collecting the
materialsandplantinginthe orchardor field in anotherlocation.
Field gene banks or living collections are the main conservation strategy
used for perennialplants,including:
• Speciesproducingrecalcitrant seeds,little or no seeds
• Vegetativepropagatedspecies
• Species that have a long life cycle to generate breeding and/or planting
material. (long-livedperennials).
• Speciesthat are preferably stored asclonal material
67. EX SITU CONSERVATION: Field Gene Banks
Preparedforacademic purpose only 67
Advantages:
Provide a safe place for plants that are unsuitable for a seed bank.
Provide opportunity for continuous evaluation for various
economic characters.
It can be directly utilized for the breeding programs
When displayed, the plants have an important educational value and
can easily be accessed for researchpurposes.
• Field gene banks are commonly used for such species as cocoa, rubber, coconut,
coffee, tuber crops, tropical and temperate fruits, vegetatively propagated
crops, such as wild onion and garlic.
68. EX SITU CONSERVATION: Field Gene Banks
Preparedforacademic purpose only 68
Limitations:
Takea great deal of space
Less genetic diversity than normal seed banks.
Field gene banks cannot cover the entire genetic diversity of
species. It can only cover a fraction of the full range of diversity of
species.
Difficult to maintain and protect from natural disasters (flood, cyclone,
fire,etc.)
Susceptibletothe spread of diseases
Costly method
Out-breeders require controlled pollinationfor regeneration fromseed.
70. DNA GENE BANKS
Preparedforacademic purpose only
70
Storage of DNA is in principle, simple to carry out
and widely applicable in the lab.
Genetic engineering has broken down the
crossabilitybarriers.
Transgenic plants incorporating genes from virus,
bacteria, fungi and even mice are reality now. E.g.
BT-Brinjal
Such efforts have lead to storage of total genomic
information of germplasm in the form of DNA
libraries.
Limitation: Strategies and procedures have to be
developed on how to use the material stored in the
formof DNA.
Genes/DNA are cryogenically frozen to protect the
genetic variation of a species.
72. Preparedforacademic purpose only 72
Orthodox seeds include for example, Citrus aurantifolia, Capsicum annum, Hamelia patens,
and most grainsand legume types

Preserving the seeds for use later is a long process,
it involves;
Cleaning
X-ray analysis
Drying, packaging and storage
Germination monitoring
Seed Banks: Process
76. Preparedforacademic purpose only 76
Occasionally clean seed is collected in the field
More often seed is collected still in its fruit
Seed must be taken from the fruit undamaged
This reduces bulk and disease risk
Seeds are often liberated by hand
Seed Banks – Cleaning
77. Preparedforacademic purpose only 77
A few seeds are taken and X-rayed
This is done to see how many of the sample are
empty seeds and find any insect larvae hiding in
the seeds
The X-rayed seeds are often thrown away
afterwards as they may be genetically damaged
Seed Banks – X-ray analysis
78. Preparedforacademic purpose only 78
Drying and freezing the seed increases the time
that the seed will last
Seeds are dried in cool conditions (15-18°C) with
the relative humidity at 11-15%
This takes about a month
The seed is then put into an airtight container and
kept at -20 °C or specified temperature.

Pollen storage was mainly developed as a tool for controlled
pollination of asynchronous flowering plants especially fruit-free
species.
EX SITU CONSERVATION: Pollen banks
80. Preparedforacademic purpose only 80
EX SITU CONSERVATION: Pollen banks
Advantage
The relatively small quantity of the specimen required for a single
accession.
Simple: Exchange of germplasm through pollen possesses fewer
quarantine problems compared with seed or other propagules.
Disadvantage
Pollen storage alone cannot conserve the cytoplasmic genetic diversity of
a species.
There is need to assess the potential drawbacks of excluding maternal
genes and feasibility of ovule storage and in-vitro fertilization
techniques.
Effective sample techniques to cover a population or gene pool are
needed.
81. Preparedforacademic purpose only 81
For conservation of tissue/meristem
cultures,tissueslike (heremeristemor
shoot tip)banksare established.
Advantages:
Germplasm of asexuallypropagated
speciescan be conserved in the form of
meristem.
Widely used for conservation and
propagation of horticulturalspecies.
EX SITU CONSERVATION: Tissue banks
e.g. MERISTEM GENE BANKS
85. EX SITU CONSERVATION: CRYOPRESERVATION
Preparedforacademic purpose only 85
Cryopreservation involves storage of plant material at low temp. (-196 °C), in
liquidnitrogenor nitrogen vapor (-154 to -196 °C).
o At this temperature the cell divisionand metabolic processesstop.
Thusplant material can be stored for longer period withoutalteration.
o Cryopreservation of those species that can easily be regenerated into
whole plants is a promising option for the safe, long-term storage of
germplasm.
o Cryopreservation requires limited space, involves very little maintenance
and is considered to be a cost-effectiveoption.

• Preservation by under-cooling has recently
been applied to plant tissue cultures.
• The objective of this approach is to maintain
tissues at low temperatures (-10 to -20 °C), but
in the absence of ice crystallization. The plant
tissues are immersed in immiscible oil and the
emulsion thus formed can be under cooled to
relatively low temperatures thereby
circumventing ice formation.
• Although good recovery has been reported in
certain species, this has only been achieved
using a temperature of -10° C and for relatively
short storage periods (6-48 hours).
89. EX SITU CONSERVATION: IN VITRO PROPAGATION
& REGENERATION

89IN VITRO REGENERATION meansre- introductionof plants to theirnatural habitats.
The propagation of a plant by using a plant part or single cell or group cell in a test tube
under very controlledand hygienic conditions is called"TissueCulture".
It plays an important role in conservation of medicinalplants in differentways like:-
• By quickly producingmature plants.
• By producing multiples of plants in the absence of seeds or necessary pollinator to
produce seeds.
• By regenerating wholeplantsfrom plant cellsthat have beengenetically modified.
• By producing plants from seeds that otherwise have very low chances of germinating
and growing etc.
