CHAPTER - IV
RESULTS . .
The present study on biodiversity of Pachamalai was carried out around
117.5 km2 against the total area of Pachamalai 14,122 km2. The study area included
three important hill ranges which are predominant form of mid-elevation forest
representative of Pachamalai. The study area included Gangavalli, Uthambium and
Manmalai, hills range and the major portion of forests is recognized by Forest
Department under the reserve forest (Topographical map of Tamil Nadu (№ 581/11)
Survey of India, Chennai). All these ranges lies between the latitude 78 29′ 20″
East and 78 42′ 40″ East and longitude 11 17′ 44″ N and 11 28′ 40″ North. Even
though they were very close and adjutant to one another, they distinctly differed in
their structure of forest vegetation (Plate-1). The types of vegetation were identified
and categorized by indicator landscape elements and considered with key parameter
in the studies of biodiversity.
The seasonal rainfall is the main water source in Pachamalai which provide
and support the existing and expanding vegetation in the study area. It received the
maximum rainfall in the months of September, October and November. During the
present study maximum rainfall was recorded by the month of October in the last
four years. However, the water with holding capacity and long-term availability to
the vegetation showed variation. The three hill ranges showed variation in the type
of forest mainly based on the water availability and soil type. After the raining
season, the water from the top hill portion flows continuously up to April and

March in Gangavalli and Uthambium respectively. Whereas in the case of
Manmalai, the available water source after raining season became withdrawn and
highly reduced within a month,
The plants in the study areas were predominantly found in the two
ecosystems i.e., terrestrial and aquatic ecosystems. Most of the vegetations were
exclusively present in the terrestrial ecosystem. The aquatic forms were represented
by small streams found around the riparian plant communities found along with
the stream and extended up to rangeland. All the stream lines aggregated in
the range land to produce a vast water reservoir in the form of small lake (Plate-7;
Fig. 21-24).
Inventory Studies
The field survey found a total of 1045 angiospermic and pteridophytic plants
which were classified into four forms based on their habit i.e., Trees, shrubs, herbs
and other forms. The fourth other forms include straggler, liane, vine, climber and
twiner. Within the angiospermic, 856 species were dicots which come under a total
of 110 families (82%), monocots have 185 species under 20 families (15%) and
pteridophytes have 4 species under 4 families (3%).
The families Fabaceae (132 species), Gramineae (69 species), Euphorbiaceae
(51 species), Compositae (48 species), Acanthaceae (47 species), Rubiaceae
(35 species), Asclepiadaceae (27 species), Malvaceae (27 species) and
Convolvulaceae (26 species) were the dominant families. In the case of monocots’
families such as Cyperaceae (51 species) and were prominently found in and around
the stream and other aquatic conditions.

Occurrence of nine threatened species of angiosperms found the threatened
species were Decalepsis hamiltonii (Fig. 81) (endangered), Santalum album
(endangered), Smilax zeylanica (Fig. 111) (vulnerable), Moringa concanensis
(vulnerable), Gloriosa suberpa (Fig. 110) (low risk), Aristolochia bracteolata (low
risk), Pseudarthria viscid (Fig. 60) (Papilionoideae), Rubia cordifolia (Fig. 74)
(Rubiaceae) and Iphigenia indica (Fig. 112). Of these, Decalepsis hamiltonii,
Smilax zeylanica, Santalum album, Smilax zeylanica, Pseudarthria viscida and
Iphigenia indica were found only in Gangavalli hills. Gloriosa suberpa was found
both in the Gangavalli and Uthambium hills. Uthambium contributes 17% of RET
plants. Moringa concanensis was found both in the Uthambium and Manmalai hills.
Aristolochia bracteolata and Rubia cordifolia were found only in Manmalai and
were recorded as a single population.
Many wild relatives of cultivated vegetable crops were identified in the study
area, they were: Canavalia mollis (Kattu avarai), Atalantia monophylla (Kattu
elumpichai), Citrus medica (Kattu naarthai), Ampelocissus tementosa (Fig. 51)
(Wild grapes), Curcuma neilgherrensis (Fig. 104) (Wild turmeric), Jasminum
angustifolium (Wild jasmine), Moringa concanensis (Wild drum stick),
Lycopersicon sp. (Wild tomato) and Solanum sp. (Wild brinjal) (Table-1).
Study of Landscape Elements
The formation and the composition of landscape elements differed in all
three hill ranges. The Gangavalli vegetation was remarkably made by dry evergreen
mixed deciduous and scrub jungle, and manmade disturbed vegetations. The
Uthambium vegetation included all the patches of dry evergreen forest. The

Manmalai predominantly possess dry evergreen, mixed deciduous, scrub jungle,
grassland and grazing land. However, the scrub jungle vegetation was found in
different altitudes in all three study areas (Gangavalli 300 m to 500; Uthambium
400m to 600 m and Manmalai 300 m to 600 m). The grassland vegetation was
exclusively present in Manmalai between the altitudes 800 m to 900 m along with
some tree species. The patches of mixed dry deciduous and dry evergreen
vegetations were found in the valley regions of almost all the three hills but differed
significantly in their range of altitude (Gangavalli 550 to 650 m; Uthambium 600 to
650 m and Manmalai 600 to 900 m).
The landscape elements were the plant representatives to that very useful
identity the vast area of land which has some unique physical and biological
environmental. In other words, landscape elements were the indicators of specific
landscape identify and demarked the forest formation. In Gangavalli, the mixed
deciduous vegetation the representative were Polyalthia cerasoides, Chloroxylon
swietenia, Citrus medica, Spondias pinnata, Cassia fistula, Ixora pavetta, Wrightia
tinctoria, Cleistanthus collinus and etc. the dry evergreen vegetation was found in
and around the altitude range from 550 m to 650 m MSL along with mixed
deciduous and some patches of scrub jungle vegetation. The dry evergreen

makes it of great ecological importance.
Study of Ecosystem Functioning
In the present study analysis of the ecosystem functioning through soil
formation and mineral enrichment studies was carried out. Ecological interactions
which included the Plant-Plant (parasitic angiosperms, hemi parasitic angiosperms
and epiphytic angiosperms) and Plant-Animal interactions (butterfly, insects, small
animals and galls), anthropogenic interactions (Cultivation, Ethnobotanical and
Ethnomedicine) was also analysed.

Soil Formation
The soil formation from barren rock was found in Gangavalli (600-640 m
above Mean Sea Level). It was observed that the rocky region along with stream
contained many patches of lichens that deterioted the rock and succeeded by
bryophytic plants such as Riccia and Richardia successfully. Further the same
places were continuously occupied by the bryophytic population. Furthermore small
herbaceous taxa and some pteridophytic plants established in these newly formed
soil. The sequential process clearly demonstrate the lithozeric (a type of xerozeric
forest formation) soil formation and initial pioneer communities of vegetation. It
was also observed that these specific region were comparatively undisturbed from
the local population (Plate 24, Fig. 148-154).
Soil Fungal Culture
The newly formed soil samples were cultured in the PDA medium
(Laboratory conditions) in order to identify the soil fungus. Interestingly it was
found that the Fusarium sp. (Fig. 155) was predominant (83.3%) the other fungus
like Rhyzopus sp and Aspergillus sp were found with each 8.3% and totally 16.6 %
formed soil of Gangavalli.
Soil Mineral Analysis
The important minerals available in the forest soil were studied both in
undisturbed forest and compared with deforested cultivated land. Along with
mineral enrichment studies, soil pH, electrical conductivity and organic matter have
also been analyzed for almost all samples (Table 5).

Population Interaction
As like mineral enrichment, population interactions with in the vegetation
have also been considered as an important factor for species richness and
establishment in the forest. The present study identified two types of major
interactions i.e., Plant-Plant interaction and Plant-Animal interactions. The first
category included the parasitic hemi-parasitic and epiphytic plant population in the
study area.
Plant-Animal Interactions
In the plant-plant interaction studies, it was observed that, most of the
Parasitic and Lemiparasitic plants depended on the branches (58%) for their
survival. Arial parts like shoots twigs supports 27% of parasitic plants such as
Stroiga (Fig. 162) and Balanophora (Fig. 96). On the main trunk only 4% of the
parasitic plant were observed in our study area (Table 7).
The second category included the plant - animal interactions. Majority of the
butterfly, bee species interacted with the plant species for nectar with the percentage
48%. 17 % of the animal species used the plants as the platform for trapping their
prey. The plant species provide the breeding centre for the 12% of the animal
species which includes insects and birds. 9 % of the animal species uses the plants
as shelter. Animal species using the plants aerial vegetative parts for feeding was
5% in our study area. 3% of the animal species were dependent on the plants for the
fruits. The animal species depending on the seeds, tuber and latex respectively each
were 2% and totally 6 %. It was found that 7% of plant populations were either

directly or indirectly associated with animal population in the study area
(Diagram-2).
For instantce, some plants acted as the breeding centre for butterflies, mints,
bugs and wasps. According to our studies the plant species such as Hugonia mystax
(Fig. 41), Plumbaga zeylanica, Lantana camara, Citrus medica and Calotropis
gigantean are being used as a place for breeding. The plant parts such as leaves,
flowers and young shoot supplies food material and the leaves itself or the branches
are the place of halting for various caterpillars of butterflies, bugs and grasshoppers.
Various leaves and shoots in young stage of various plants species are the fodder
for grassing domestic animals such as cows, goats and sheep. The goats were eating
almost all the plants available in the study area which are at the reaching height. It
was observed that the goats eat even the poisonous leaves of Cleistanthus collinus
(Fig. 98) but in minimum quantity. Almost all the cyperaceae and graminae
members are being the fodder for the domesticated cow herds found the study area.
Ants are making their shelter with the help of the Syzygium cumini leaves.
And they derive their food from the Tamarindus indica, Morinda coreia, Calotropis
gigantean and Canavalis virosa. The plants such as Tridax prochumbens, Cadaba
fruticosa, Stachytarpheta indica, Leucas aspera, Tarenna asiatica, Parthenium
hysterophorus, Notonia grandiflora, Sarcostemma intermedium, and Pavetta indica
are providing nectar for various butterflies like Acraea violae, Appias albino, Borbo
cinnara, Junonia almanac, Danaus chrysippus, Pachliopta hector, Hypolimnas
misippus, Neptis hylas, Papilio demoleus and Euploea core. Among the plant

supplying nectar to butterflies Leucas aspera supports the maximum number of
species.
The honey bees get their nectar from the following plant species, Craea
violae, Appias albino, Borbo cinnara, Junonia almanac, Danaus chrysippus and
Euploea cor. The trees like Terminalia arjuna, Syzygium cumini and etc., provides
the place for making hives of honey bees. Croton bonplandianus, Cissus
quadrangularis, Malvastrum coromandelianum, Lantana camara, Leonotis
nepetiifolia, Justicia tranquesbariensis and Canavalis virosa are the plants which
support the insects and beetles. Calotropis gigantea, Argemone Mexicana and
Ageratina adensophora are the plants supporting the grasshoppers. Dragon flies use
the plants like Leucas aspera as the platform for trapping insects.
Leucas aspera, Caralluma umbellate, Anisomeles malabarica, Euphorbia
antiquorum, Caralluma attenuate, Sarcostemma intermedium, Passiflora foetida
and Justicia tranquesbariensis provides places for web making and ideal place for
trapping insects which visit their flowers in seek of nectar.
The plants such as Leucas aspera, Caralluma umbellata, Anisomeles
malabarica, Euphorbia antiquorum, Caralluma attenuate, Sarcostemma
intermedium, Passiflora foetida, Justicia tranquesbariensis and Cuscuta chinensis
were foraged by flies and they provide nectar for them. It was also observed that the
plants which support flies are also being the place of spider shelter. Anisomeles
indicus, Justicia tranquesbariensis and Citrus medica are the plants which provided
nectar and shelter for wasps. The plants such as Coccinia grandis, Borassue
flabellifer and Cocos nucifera provide the fruits and sheltering place for various

birds. The deciduous tree Moringa concanensis is being the wonderful place for the
lizard to stay as the tree bark and skin of the animal are almost same in appearance
and simplify the hunting process of lizard (Plates 20-23).
In Pachamalai, barking deer and wild boar were depend on some selected
taxa for their food source such as the tree species Sapindus emarginata and
Dioscorea pentaphylla (Fig. 108)respectively and their population number is being
steadily reduced in the past four year’s survey. Therefore the depended animals
have also been limited to food source and they go for alternative available plants in
the study area (Table 6).
Anthropogenic Interaction Studies
It had been identified in three ways namely agricultural practices,
ethnobotanical and ethnomedicines. The agricultural practices have been
extensively done in both, range land and hills tops. The hills tops were chiefly
occupied by the tribal people and it was found that 10-15 families inhabited in
Gangavalli and Uthambium permanently practiced agriculture. Whereas the top
hills of Manmalai soil is completely eroded and unfavoured for the cultivation.
It was found that the shifting and expansion of agricultural land on top floor
can cause the disturbance to the natural vegetation. The low level of rainfall in all
three hills also created problems in the settled agriculture of tribal people.
Agro-biodiversity Studies
Mostly the hills top land was used the cultivation of 11 agricultural crops.
Among them, Eleusine coracana gave 8 % of the total productivity, Panicum
miliare gave 12 % of the productivity, Oryza sativa (verity I) (Mara Nellu) 9 %
![Page 21: Anburaj Thesis - Final](https://reader035.fdocuments.us/reader035/viewer/2022071601/613d47c1736caf36b75b755f/html5/thumbnails/21.jpg)

gave productivity and Oryza sativa (verity II) gave 11% of the production totally
20%, the productivity of Manihot esculenta was 16 %, Macrotyloma uniflorum gave
2 % of productivity, Vigna mungo supports the tribals with the productivity of 3 %
of the total productivity of the uphill crops. Sesamum orientale supplies the edible
oil need with the 11% of total productivity, Paspalum ps give maximum yield with
17% of the total productivity i.e., 655 kg/acre. Pennisetum americanum and Setaria
italica gave the productivity of 6% and 5% of the productivity respectively (Table-9
and Diagram-3). Whereas in the case of range land occupied by the tribal and non-
tribal people. Almost 13 crop varieties were cultivated in the range land by tribal
and non-tribal community; they are as follows, Zea mays, Allium cepa, Manihot
esculenta, Arachis hypogaea, Musa paradisiacal, Saccarum officinarum, Curcuma
domestica, Oryza sativa, Vigna mung, Sesamum orientale and Helianthus annuus.
Among all the corps studied Saccarum officinarum gives maximum production with
18140 kg/acre (Table-10).
During the agricultural process, the native flora of forest was disturbed and
devasted from parental lands. The present study have also observed the low rainfall
concomitantly with increasing temperature on hills tops has caused the shifting of
agricultural land have lead to the damaged species distribution pattern in natural
ecosystem which indirectly has affected the ecosystem functioning.
Ethnobotany and Ethnomedicine
The percentage of plant parts used for ethnobotanical and ethno medicine is
given in the Table-11 and Diagram-4. Totally 39% of the tribal’s ethnobotanical
activities were dependent on the leaves of the plant species found in the study area.
![Page 22: Anburaj Thesis - Final](https://reader035.fdocuments.us/reader035/viewer/2022071601/613d47c1736caf36b75b755f/html5/thumbnails/22.jpg)

Root supports 15 % of the ethnobotanical and ethnomedicinal need. Next to this
fruits support 11 %. Remaining needs were supported by fiber, branch, nuts, prop
roots, rhizome, seeds, stem, trunk, tuber, wood, young shoots, bark, flowers,
inflorescence, latex and in some cases the whole plants.
The tribal community has utilized wild plants having ethnomedicine and
ethnobotanical values for regular uses. The plants which are having ethnomedicinal
value is used for various ailments such as stomachache, vomiting, skin disease,
fever, headache, body pain, boils, swellings, scorpion sting, snake bite and venereal
diseases and others such as ethno-veterinary uses. Some of them are Cleistanthus
collinus, Helicteres isora, Cissus vitiginea, Cardiospermum canescens,
Pseudarthria viscid, Acacia torta, Passiflora ediulis, Randia malabarica, Tarenna
asiatica, Decalepis hamiltonii, Mallotus philippinensis, Dioscorea oppositifolia,
Toddalia asiatica and Actiniopteris radiata which are exclusively found in the hills
area of Pachamalai and not in foothills and surroundings. The ethnobotanically
valued plants were used for hut making, designing agricultural implements,
furniture, rope making and other purposes, few of them are Acacia caesia,
Canthium dicoccum, Pavetta tomentosa, Tarenna asiatica, Sansevieria
roxburghiana, Cymbopogon martini, Commiphora caudata and Hugonia mystax.
The following plants are known to be used as edibles for their fruits and
seeds Passiflora ediulis, Passiflora foetida, Coccinia grandis, Opuntia stricta,
Randia malabarica, Salvadora persica, Caralluma attenuata and especially
Dioscorea pentaphylla is a well known edible tuber among the tribal people.

Antibacterial activity studies
Some important medicinal plants as referred by the tribal people were
selected for antibacterial studies in order to find out the efficiency of plants against
the bacterial pathogens. The leaves of the plants such as Helicteres isora, Claucena
dentata, Ampelocissus tomentosa, Acacia sinuata, Pavetta indica, Blepharis
maderaspatensis, Stenosiphonium parriflorum, Dioscoria oppositifolia, Hemionitis
arifolia and Cleistanthus collinus were tested for antibacterial and antifungal
activities in various concentrations such as 25, 50, 75 and 100 µl. Out of them
Cleistanthus collinus showed maximum inhibition against the bacteria such as
Escherichia coli (2.5 mm), Steptococcus (2.4 mm), Salmonella (2.5 mm) diameter
of inhibition zone. All the ethnomedicinal plants showed significant antimicrobial
activity in all the concentrations expect few plants in 25 µl concentrations
(Table-12).
The study area is dominated with agriculture fields interspersed with forest
patches and many villages such as Edapadi, Meelpaalthankarai, Keezh
paalthankarai, Valasakalppatti, Chinna Karattoor, Periya Karattoor, Naripaadi,
Uthambium and Manmalai. Intense pressure for fuel wood and livestock grazing
and the movements of livestock were persistent and significant sources of intense
biotic pressures. This is not an uncommon situation in Indian forests by any means.
