We provide a check list of angiosperm plant species with their bioresource potential as medicinal plants enumerated from a total of seventy-five tropical dry evergreen forest sites along the Coromandel coast of peninsular India. These are poorly known sites even within Indian sub-continent and form an under-studied forest type. Tropical dry evergreen forests harbour 312 species belonging to 251 genera and 80 families. The families with the greatest numbers of species were Euphorbiaceae (20 species), Apocynaceae (18 species), Rubiaceae (15), Fabaceae (12), Mimosaceae (11) and Capparaceae and Asteraceae (10 each). Physiognomically evergreen species dominated the forest. Plant specimens are identified and confirmed using regional floras. These forests are conserved by the local people on religious ground as sacred groves, although they are also subjected to various levels of anthropogenic impacts.

Pandian E, Parthasarathy N. 2017. Tree growth, mortality and recruitment in four inland tropical dry evergreen forest sites of Peninsular India. Biodiversitas 18: 1646-1656. Tree diversity was re-inventoried after a decade (2003-2013) for assessing growth, mortality and recruitment rates in four inland tropical dry evergreen forest sites on the Coromandel Cost of India. Four 1-ha square plots (100 m x 100 m) were established in 2003 in four tropical dry evergreen forest sites, i.e. Araiyapatti (AP), Karisakkadu (KR), Maramadakki (MM) and Shanmuganathapuram (SP). These four plots were re-inventoried in 2013 to determine decadal changes in tree diversity. All trees ≥10 cm girth at breast height (gbh) were measured at 1.3 m from the ground level. The initial inventories in 2003 recorded 57 tree species, whereas, in 2013, 56 species were recorded from 46 genera and 26 families. Tree basal area declined by 6.2 % and 3.4 % in sites KR and SP respectively, whereas in the other two sites it increased; AP (1.6 %) and MM (16.8 %). The mean growth rate of trees (≥ 10 cm gbh) in four tropical dry evergreen forest sites ranged from 0.68 to 1.52 cm yr-1. High recruitment rate was recorded in less disturbed sites KR (21.8 % yr-1) and MM (11.5 % yr-1), while the moderately disturbed sites showed 9.1% yr-1in site AP and 5.1 % yr-1 in site SP. Mortality rates were 23.5 and 45.7% yr-1 in highly disturbed sites AP and SP respectively.

Tropical Dry Evergreen Forest

Abstract During the last two decades of intensive botanical survey of the tropical dry evergreen forest, a total of 82 endemic taxa were found out of 1142 species enumerated from 85 sites in the three Coromandel Coastal districts of the state Tamil Nadu: Cuddalore, Kancheepurm and Villupuram, and in the Pondicherry district. Of 82 species, 17 are trees, 11 shrubs, 9 climbers and 45 herbs. Distribution of these endemic species was analyzed and categorised as endemic to the country, peninsular India, southern India, Eastern and Western Ghats, and at the state and district level. Interestingly, the study found that some endemic species were disjunctly distributed between districts, states, ghats, climatic regimes and bioregions. Anthropogenic disturbance and species threat status were also studied and discussed.

Coromandel Coast

The central area of the Coromandel Coast, southeastern India, has been subject to a very long history of human habitation and land use change, substantially reducing the coverage of native forest.  There are polarised views about definitive characteristics of native tropical dry evergreen forest (TDEF), albeit agreement that the habitat type is locally characteristic though now severely reduced, fragmented and degraded.  A literature review was undertaken to determine the evolutionary origins of TDEF as well as its characteristics.  A combination of both natural and human factors gives rise to TDEF, explaining the heterogeneity of existing stands even in close proximity to each other.  Religious shrines are often associated with ‘sacred groves’, which are influential in the survival of stands of TDEF.  These remaining stands are highly fragmented across the wider landscape and subject to species invasions from adjacent habitats as well as increasing human pressures.  On the basis of existing evidence, it is not possible to describe TDEF through a definitive community of tree species, though typical constituent species are listed.  TDEF may therefore be representative of a larger biome, as for example ‘tropical rainforest’, rather than a specific vegetation type.  Nevertheless, there is general consensus about the importance of restoring TDEF, including its many associated plant and animal species, many of which have medicinal, spiritual and other uses and meanings.  Regardless of biological definitions of TDEF, the functions it performs and the diversity of ecosystem services that it provides afford it substantial importance and reinforce the case for its protection and restoration.  Successful local restoration activities highlight the feasibility of regeneration of TDEF, even from severely degraded and eroded land, and the associated regeneration of ecological and socio-economic values.

We provide a checklist of Angiosperms along with the details of life form from a ~ 9.6 ha of non-concreted area of Pachaiyappa’s College (PC) campus, Chennai, Tamil Nadu state, India. This area harbors 256 species belonging to 212 genera in 71 families. Families with maximum number of species include Fabaceae (31 species) followed by Malvaceae (15), Euphorbiaceae (13), Apocynaceae (12), Acanthaceae and Poaceae (11 each), Bignoniaceae and Rubiaceae (eight each) and Arecaceae, Moraceae, Rutaceae and Verbenaceae (seven each). The surveyed area represents a remnant of tropical dry evergreen forest (TDEF), as a substantial number of species collected in the present study belong exclusively to the Coromandel Coast (CC) TDEFs. PC is still preserving the biodiversity by means of strict rules and regulations enforced for the maintenance of the college premises.
