Bio-geographic zonation
As per the Biogeography classification adopted by Wildlife Institute of India, Dehradun, this sanctuary is classified as follows. 
i) Bio-geographic Kingdom - Paleotropical
ii) Sub Kingdom - Indomalaysian
iii) Bio-geographic Zone - 6 – Deccan Peninsula
iv) Biotic Province - 6 B – Central Deccan.
This Bio-geographic zone is one of the least protected bio-geographic zones in India, rich in floral and faunal diversities. Hence it needs high degree of protection.  Nagzira Wildlife Sanctuary is within the Central Deccan Plateau dry deciduous forests ecoregion.

The total length of the external boundary is 104.53 km out of which 74.93 km is an artificial boundary and 29.60 km 
length is natural boundary.  As per the notification the external boundaries are as follows.

On the South - Pitezati fazal forests and Sakoli Range, village boundaries of Jamdi, Kosamtondi and Reserve Forest boundary.
On the West - Village boundary of Bhajepar, Chorkhamara, Chorkhamara-Pangdi Cart track and Reserve Forest boundary.

Village boundary
Thadezari is the only village geographically situated inside the sanctuary. This village boundary coincides with the Compt. Boundary. 
At present the sanctuary area is not classified into various zonation. So the zonation boundaries do not exist. All these types of boundaries need to be demarcated and mapped permanently. The boundary demarcation within the sanctuary should be distinct from the normal forest boundary.

Ecological boundaries
The forest area surround the sanctuary is a self-sufficient ecosystem with its living fauna and flora.  There is no marked difference between the vegetation and the topography of the surrounding areas with that of the sanctuary.  As the present sanctuary area is small, it is not viable in itself.  It is with these considerations the extension of this sanctuary is proposed and the same has been recommended by the Wildlife Institute of India’s study in the "Protected Area (PA) Network" for the State.

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 and 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 anthropogenic 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.

Museum

Museum and Interpretation Center
Presently a small museum at Nagzira tourist complex is being used for conservation education of tourists.  Here varieties of stuffed birds are kept in showcases. Some animal models, butterflies are also displayed at museum.  Also some photographs on wildlife, pugmarks, hoot-prints, plaster casts etc.  are also exhibited to educate the tourists.  This Museum is at its infancy and needs lot of further improvements.  Very few tourists visit the museum/ Interpretation Center.

Auditorium and audio-visual materials
Presently museum/ interpretation center is use as an auditorium to screen informative films and slides on wildlife, forests and nature. At present there are 8 films are lent out occasionally to other institutions like schools, colleges and other forest divisions.  At present only one 16 mm film projector, one 35 mm slide projector, one overhead projector as well as two tape recorders are available with the sanctuary. As there is no electricity within the sanctuary, the generator is used to operate these facilities.  Hence there is no need to develop facilities within the sanctuary.

Hides and machans
At present there are 5 watch cabins and 5 watchtowers located within the sanctuary.  This facilitates wildlife observation. The existing number of watch cabins/watch tower is quite inadequate and hence there is need to erect more watch cabins/ tower within the sanctuary during the plan period.
