ABSTRACT

The wealth of vegetation that adorns the earth shows a vast array of floristic diversity ranging from microscopic algae to gigantic Eucalyptus. Among these, gymnosperms, particularly conifers, constitute an important floristic component of evergreen forests by virtue of their multidimensional ecological and socio-economic values. In view of their immense importance, a thorough study has been undertaken to explore the conifers of Kashmir. During the present investigation, a total of 16 species, spread over 9 genera in 3 families, were recorded. Among these, the family Pinaceae with 7 species in 4 genera is the most dominant, while Taxodiaceae with 2 species in 2 genera is the least represented. Out of the total taxa 7 species, belonging to 5 genera, are exotic and exist in cultivation only.

INTRODUCTION

Living gymnosperms are one of the great antiquity and include about 700-800 species in 70-75 genera. Among gymnosperms, conifers with about 550-600 species in 50 genera, form the most dominant group. Conifer forests are typical of Himalaya and provide a cool and soothing environment for recreation and health. Forests, verily the green gold of the State of Jammu and Kashmir, are dominated by conifers. These cover considerable proportion of the area of our State and contribute to its most important industries, hence the mainstay of economy. Most of the timber used in buildings is derived from conifers because of their straight-grain and ease of manipulation. Deodar is the strongest of the Himalayan coniferous woods; the blue-pine is much used in house construction and lighter furniture.

Notable as a source of pulpwood for paper manufacture are pines, firs and spruces. Conifers are effective for erosion control, protection of watersheds and wind control. Some conifers are source of foods (for wild life and birds), medicines, oils, dry fruits, ornamentals, bonsai, etc. Despite their immense ecological and socio-economic importance, taxonomy of conifers has met negligence in India, especially Kashmir Himalayan region. Even though Hooker (1888) gave the first treatment of gymnosperms in India, but he has cited very little material from this region. Since then, some local workers (for example, Lambert, 1933; Dhar, 1966, 1975, 1978; Stewart, 1972; Javeid, 1970, 1979; Singh and Kachroo, 1976; Sahni, 1990; Dar et al., 2002; Dar and Christensen, 2003; Dar, 2004) have also made attempts in this direction, but the overall picture is not complete. It is in this backdrop that the present study of conifers in Kashmir is attempted.

MATERIALS AND METHODS

During the present study various forests in the Kashmir Valley were explored every fortnightly from April 2002 to April 2003. For collection purposes, polythene bags, shears, tags, specimen bottles, field-note book were used. Four or five specimens of each species in a locality were collected in the form of twigs, usually cone-bearing ones. The specimens were assigned a specific field number and on spot diagnostic field characters were noted in the field-note book. The specimens were arranged in paper folds and pressed. The paper was changed after every 24 h until the specimens dried fully. In case of Abies, Picea and Cedrus, where all the leaves fall down the twigs a few days after direct pressing, the specimens were put in boiling water for one to two minutes prior to pressing, even then the needles fell. The method proposed by Page (1979) proved effective in these cases. The specimens were kept in 70% alcohol for 10 min and then transferred to 50% aqueous glycerol solution for 4 days. After this, the specimens were air-dried for sometime and placed in paper folds to be pressed as usual. The female cones of Cedrus and Abies, where cone scales fall while still on the tree, were collected just prior to dismembering stage and kept air-tight in small polythene bags, so as to keep them intact. The male cones were preserved in 70% alcohol for further study. The specimens were identified using the available literature on floristics of this region. The identifications were confirmed by matching our specimens with those deposited in the Kashmir University Herbarium at the Centre of Plant Taxonomy. For specimen description, specimens from different localities were examined minutely, using magnifying lens and dissection microscope. Numerical characters, wherever possible, were also taken into account.

Study area: The Valley of Kashmir is acknowledged as ‘paradise on earth’ for its diverse rationale. It lies between 33° 20' and 34° 54' N latitudes and 73° 55' and 75° 35' E longitudes. It extends roughly 107 km in length and about 116 km in breath along the latitude of Srinagar and covers an area of 15,948 sq km. It is believed that the Valley of Kashmir was once a lake called Satisar. The entire territories of Valley form two distinct topographic divisions, the mountain ranges and the Valley proper. Mountains vary in height and surround the Valley on all sides. The Valley is an oval plain with a girdle of mountains. There is sufficient organic matter and nitrogen content in the alluvium of the Valley as a result of plant residues, crop stubbles, natural vegetation and animal excretion. Himalayan ranges play the major and determinant role in determining the climate of the Valley. In general, the climate of Valley is sub-mediterranean with bixeric regimes. A unique feature of the climate is the four clear-cut seasons. Annual rainfall is about 75 cm, with sufficient rains during March and April and also July and August; precipitation in winter is in the form of snow. August is the warmest month, when temperature rises to 29.5°C; January is the coldest month. The maximum relative humidity (80%) occurs during November-December and lowest (71%) during May.

RESULTS AND DISCUSSION

Coniferales: Monoecious or dioecious trees, rarely shrubs. Photosynthetic leaves evergreen, rarely deciduous (Larix, Taxodium), spiral, distichous or whorled, solitary or in fascicles, entire, often needle-like, awl-shaped or scale-like, sometimes broad, ovate and parallel-veined (some Podocarpus spp.). Male cones terminal or lateral, microsporophylls with 2 (-20) pollen sacs. Female cones with a central axis having spirally arranged seed-scale complexes all around, ripening in 1-3 years.

About 50 genera with approximately 550 species; of these 30 genera are confined to the Northern hemisphere, 14 to the Southern hemisphere, whereas 6 genera are represented in both the hemispheres. Conifers are well represented in India, especially in the northern and eastern Himalayas.

Wild and cultivated conifers: The conifers of Kashmir Himalaya can be categorized into wild and cultivated, as detailed in Table 1 and 2.

DISCUSSION

From the present investigation it appears that conifers of Kashmir comprising of 16 species in 9 genera and in 3 families, represent a handsome proportion of species of conifers found in India. Although conifers of Kashmir represent only a meager proportion of total species count of plants (angiosperms, gymnosperms and others) of Kashmir, still they exclusively dominate the forest vegetation of this area. Some species namely, Pinus wallichiana, Cedrus deodara, Abies pindrow and Abies spectabilis etc. form the most important sources of the timber for construction purposes and hence forming the backbone of the timber industry-the mainstay of the States economy. The other aspects of the gymnosperm species such as medicinal, ethno botanical and economical have great potential and market demand. The medicinal properties of the berries of Juniperus communis and other species can be of great potential, especially when our sub alpine and alpine landscapes are exclusively dominated by the shrubs of these species.

In the present study, it has been found that there is complexity in genus Abies, as besides the two species, i.e., A. pindrow and A. spectabilis there exists many hybrids between them in Kashmir Himalaya, and has a great promise for further research. These hybrids show various degrees of intermediacy in characters, such as bark, leaves (arrangement, apex notching, margin recurving, groove prominence), cone characteristic (axis length, thickness, swollen or pointed tips).

In case of genus Juniperus, it has been found that J. recurva reported by previous workers from our area (Hooker, 1888; Gamble, 1902; Gaussen, 1968; Singh and Kachroo, 1976; Sahni, 1990), is actually Juniperus squamata. Furthermore J. macropoda reported from northern Himalaya under various names ( e.g., J. excelsa, J. polycarpos ) by various workers (Lambert, 1933; Raizada and Sahni, 1960; Sahni, 1990) has been found to be actually J. semiglobosa, an entirely distinct species (Dar et al., 2003). J. pseudosabina has been reported from Kashmir by many previous workers (Lambert, 1933; Gaussen, 1968; Mehra, 1988; Hooker, 1888; Gamble 1902), but we have not found it in the Valley. The present communication is an attempt to provide exact documentation of the conifer flora of Kashmir Himalaya. Out of total, 9 species in 5 genera and 2 families occur as wild (Table 1) and 7 species belonging to 5 genera in 3 families (Table 2) exist in cultivation and are cultivated in garden, parks, open rocky slopes where other trees hardly flourish. Over the years it has been found that these cultivated conifers have established themselves with ease and flourish well. Certain cultivars (Pinus halepensis, Cupressus torulosa, C. semperverens, Thuja orientalis) have grown into small forests at some places, depicting that these have got bright prospectus in this region.
