FOREST TYPES:
The sanctuary has a diversity of plant community.  The major forest type is “Southern Tropical Dry Deciduous Forests” – 5 A/c 3 as per Champion and Seth’s Classification.

Mixed Forests :

They are rarely semi-evergreen in hot season more or less without leaves. Thorny plants occur.  Bamboos are often present on slopes.  Grass is conspicuous, climbs are there. These forests occur over the large area in the sanctuary.  Generally good quality forests are found in pockets on deep moist soils in valleys and along nallas.  Erosion due to incidence of grazing is seen on the outskirts of the sanctuary near villages.  Average density of the crop in the stocked area is between 0.5 to 0.75.  The crop in general is young to middle age, with few matured trees in the over wood.  The major tree species are Terminalia tomentosa, Lagerstroemia parviflora, Anogeisus latifolia, Pterocarpus marsupium, Dispyrus melanoxylon, Tectona grandis, Bombax ceiba, Lannea grandis, BoswelIa serrata, Adina cordifolia, Xylia xylocarpa, along nallas Terinalia arjuna, Syzyguim cumini, Schleichera oleosa, Terinalia Chebula, Many Shrubs and Herbs like Holarrhena antidysentrica, Wrightia tinctoria.  Woodfordia fructicosa, Helicteres isora etc.  Climbers which are of common occurrence are Combretum decandrum, Zizyphus oenoplia, Calycopteris floribunda, Butea superba, Bauhinia vahlii, Smilax macrophylla, Mucuna pruriens, Acacia pinnata, Grass – Themeda quadrivalvia, Iseilema laxum. Apluda varia, Eragrostis tennella, Cynodon dactylon, Imperata cylindrica, near the lake – Vetiveria zizyniodes, Heteropogan contortus, Schima nervosum, etc. Bamboo on slope and along nallas. 

Teak Forests :

These forests occur on hill slopes though their extent is not much.  Besides this teak plantations, have been raised earlier.  These can be seen interspersed with natural forest.  The principal associates of the teak are Terminalia tomentosa, Anogeissus latifolica.  Pterocarpus marsupium, Lagerstroemia spp.. Madhuca indica and Bamboo- Dendrocalamus strictus.

GRASSLANDS:
Grassland can be seen near Nagzira but it is of small size and anthoropogenic in origin.  Earlier Nagzira Forest village was located here which was later on shifted to Thadezari in this grassland encroachment by woody plants is advancing and needs to be checked.  Around 125 Ha.  Of grasslands exists.  These are located in compt.  No. 95, 96, 97, 98, 121, 125, 126.

BAMBOO:
Bamboo occurs in abundance over the central portion of the sanctuary where deep soil combined with moisture is seen.   They grow as middle storey in teak as well as mixed forests.  There is no exploitation of Bamboo but illicit cutting is continuous threat and because of this Bamboo is either absent or of very poor quality in areas on the outer fringes of the sanctuary.

It is evident that there is diversity in plant community. The communities have some distribution pattern, which has resulted into distribution of edges, interspersion and juxtaposition of habitats.

SPECIES OF CONSERVATION IMPORTANCE:
This sanctuary serves as a living repository of various economical, medicinal, aromatic, ornamental plant species.  Nearly 200 species of medicinal and economical importance are seen in this sanctuary.  So far, there is no record of any endemic or rare species form this sanctuary.  It is necessary to study the flora of this sanctuary in great detail for this purpose.  The help of an expert in flora identification needs to be sought in this regard.

WEEDS :
The most common weeds seen in this sanctuary are Lantana camera (Ghaneri) which is an exotic shrub and Parthenium spp.  (Congress grass) which is an exotic herb.  Weed infestation though on small extent is seen in the compartment nos. 86, 96, 97, 101. 109, 112, 116, 125 and 128.  The further spread of such weeds within the sanctuary should be checked and effective weed control methods like uprooting before flowering and then baring should be periodically cleared and be planted with suitable local fruit/fodder species useful for the existing wildlife.  The species suggested are Mango, Bor, Sitaphal, Wad, Jambul, local varieties of palatable grasses etc.
