in the category are considered as a mixture of both evergreen <strong>and</strong> deciduous<br />

type of tree growth. This forms a closed forest. Such type is met with around<br />

Mambazhathara <strong>and</strong> Kottakkayam in Achenkovil Reserve <strong>and</strong> in folds of hills<br />

<strong>and</strong> higher portions in Yeroor Reserve. The natural regeneration is<br />

comparatively less, because of more biotic interference. This type of forest is<br />

approximately 400 ha the floristic composition is as below. Top Canopy:<br />

Artocarpus hirsutus, Hopea parviflora, Terminalia paniculata, Terminalia<br />

tomentosa, Lagerstroemia lanceolata, Salmalia malabarica, Tetrameles nudiflora,<br />

Vitex altissima, Vateria indica, Terminalia bellerica etc. Lower canopy: Mallotus<br />

philippinensis, Albizia odoratissima, Macaranga petata, Cinnamomum<br />

zeylaniucm, Bridelia retusa etc., Under Growth: Glycosmis pentaphyla, Butea<br />

parviflira, Dioscorea Species, Strobilanthes etc., Climbers: Entada phaseoloides,<br />

Strychnos colubrine. The tropical evergreen forests that were subjected to heavy<br />

interference have changed to this type. It is now in a transitional stage from<br />

evergreen to deciduous owing to the change environment.<br />

(3). Southern Moist Mixed Deciduous Forest (3B/C2): Major portions of the<br />

forest in this Division are of this type. Deciduous species are dominant. In the<br />

lower canopy, evergreen species are also met with. Wherever the canopy is<br />

opened up, weeds <strong>and</strong> grasses have colonized. Annual fire is a recurring<br />

phenomenon. Agood percentage of this type of forests exists in Achenkovil <strong>and</strong><br />

Yeroor Reserves <strong>and</strong> in in the remaining uncleared areas of the Division. This<br />

type, extents over an area of approximately 6,758.17 ha. Regeneration is<br />

moderate. But the establishment of seedlings is affected badly by fire, grazing<br />

etc. The floristic composition is as below. Top Canopy: Terminalia paniculata,<br />

T. tomentosa, T. bellerica, Pterocarpus marsupium, Tectona gr<strong>and</strong>is, Dalbergia<br />

latifolia, Salmalia malabarica, Adina cordifolia, Grewia tilifolia <strong>and</strong> Albizia<br />

species. Lower Canopy: Mitragyna parvifolia, Dillenia pentagyna, Mallotus<br />

phillippinensis, Emblica officinalis, Careya arborea, Cassia fistula etc.<br />

Climbers: Lantana, Acacia pinnata, Butea parviflora, Acacia intsia, Bauhinia<br />

vahli etc Grasses: Imperata cylindrical, Andropogan Species. Shrubs:<br />

Eupatorium odoratum, Helecteris isora, R<strong>and</strong>ia dumetorum etc. (4). Grassl<strong>and</strong>s:<br />

Grassl<strong>and</strong>s occur bordering the semi evergreen <strong>and</strong> deciduous forests,<br />

wherever there are significant openings. As a matter of fact, these are created<br />

due to degradation of forests <strong>and</strong> are not true grassl<strong>and</strong>s. The extent of<br />

grassl<strong>and</strong> in the Division is included in the previous types stated above. These<br />

formations harbor tall coarse grass with sporadic tree growth. The trees<br />

present are Emblica officinalis, Careya arborea, Pterocarpus marsupium etc.<br />

Annual fire <strong>and</strong> grazing causes the extension of grassl<strong>and</strong>. Common species of<br />

grasses are thatching grass <strong>and</strong> lemon grass. 2A.2.5. Plantations Kerala<br />
