Sagalee Forest Division

General: The uncloassified forest areas of Sangalee Forest Division are rich in wildlife and therefore this working circle is constituted to ensure effective protection and conservation of wildlife. This is an overlapping working circle, which is spread over the entire area under this working scheme. The important wild animals found in the forests have been given in the following paras. The division is rich in biodiversity. In the past wild animals were in abundance in the region. But of late with the increase in human population, forests have been put dwindled due to the poaching and customary hunting by local tribals. The important wildlife spp. Found in the forests of the Division are given below:

The objectives of this working circle are -
1. To conserve and preserve natural ecosystem and rich biodiversity of the region.
2. To protect the wildlife and their habitat and create favorable condition conducive. The growth and development of wild flora and fauna.
3. To preserve and protect the rare and endangered wildlife found in these areas and to increase their population through scientific measures.
4. To maintain natural corridors for migration of wild animals.
5. To ensure collection of scientific data in the interest of better and effective management and development of wildlife.
6. To reduce to the maximum possible extent, the incidence of poaching and hunting by local people as customary practices and by organised miscreants for unlawful trading activities.

Forest Types:The forest under this working scheme are Semi-Evergreen on nature and comprise of large number of tree species, which occur in varying proportions at various localities. The area is located in a zone of high rainfall, the dry season being short and the average humidity is relatively high. The main feature of this forest is the heterogeneous mixture of species a clear description of which is difficult. Structurally this forest can not be clearly differentiated into distinct stories. However at places specially on hills two stories can be identified depending upon species composition. In general the top story is rather open and composed of a mixture of evergreen, semi-evergreen and deciduous species. Pure patches of bamboo are also common and are scattered all over the forest area. This forest can be grouped in the sub-ground 2B' Northern Tropical Semi Evergreen Forest of Champion and Seth's revised classification of forest types of India and can further be grouped in following forest sub-types.
I. 2B/CI (A): Eastern Sub-Montane Semi Evergreen Forest.
II. 2B/CI/ISR: Sub-Himalayan High Alluvial Semi Evergreen Forest.
III. 2B/2SI : Secondary Moist Bamboo Brakes.

General description of the forest types: As mentioned in above para the Forests found in the working plan area are diverse and consists of a mixture of large number of tree species. However the forests are aptly grouped in following sub-type depending upon species composition and similarity of important characteristics and each sub-grouped is discussed in detail one by one.

Evergreen species are dominant though deciduous species are also present in significant proportion and the forest is a mixture of both species. Middle storey is prominent and consists of mixture of evergreen and deciduous species with abundant shrubby undergrowth. Floristic composition of this forest is almost same as that of 2B/C1 (a) the important variation being prominence of Jutuli (Altingia excelsa) and Hollock (Terminalia myriocarpa).

III. Secondary Moist Bamboo Brakes 2 B/2S1: Secondary Moist Bamboo Brakes occur in scattered patches throughout all the tropical Evergreen forests in the various Reserve Forests of the Division. When bamboo brakes overhead trees, they form thinner clump. Where bamboo patches are pure, the clumps are and there is no possibility of regeneration of any other tree species in these bamboo . At places, shrubby and grassy under growth is found. The bamboo species found in forest are given below :-
A) Kako Bans: Dendrocalamus hamiltonii, B) Bijuli Bans: Bambusa pallida, C) Bojal Bans: Pseudostrachyumpolvmorphum
