Goal: Thematic Botanic Gardens are unique as besides playing a crucial role in conservation and research on various genotypes they provide an opportunity to people to see a range of plants belonging to the same category at one place which is otherwise not possible in classical Botanical Gardens. The main Goal of the project is to establish a unique Thematic Garden in SNU with the following themes:
Theme 1: Endemic and RET Species Garden
Theme 2: Orchidarium (Green House)
Theme 3: Fruit Plants Garden
Theme 4: Bamboo Garden (Bambusetum)
Theme 5: Palm Garden (Palmetum)
Theme 6: Ficus Garden
Theme 7: Medicinal Plants Garden
Theme 8: Gymnosperms Garden
Theme 9: Aromatic and Essential Oil Plant Garden
Theme 10: Anticancer Plants Garden
Theme 11: Antimalarial and mosquito repellant plants Garden
Theme 12: Anti-Oxidant Plants Garden
Theme 13: Aquatic Plants Garden and Conservation Area
Theme 14: Xerophytes Garden (Arid & Semi-Arid Zone Plants)
Theme 15: Cacti and Succulents Garden (Green House)
Theme 16: Thallophyte & Bryophyte Garden (Cryptogams Garden)
Theme 17: Fern and Allies House (Green House)
Theme 18: Butterfly Garden
The Thematic Botanical Garden is being established in an area of 4.33 ha (10. 63 acres) adjacent to the wetland area of the Campus, including 3.28 acres (1.33 ha) of low lying wetland area; the land area of the Garden is 7.45 acres (3.00 ha) in the Campus of Shiv Nadar University. The wetland part, which provides habitat for aquatic life – flora and fauna, especially the migratory and other aquatic birds, amphibians, fishes, reptiles such as tortoise and snakes are common. The wetland side of the Garden having a number of aquatic species (Sagittaria sp., two species of Potamogeton sp., Hydrilla sp., Nitella sp.(Algae), Chara sp.(Algae)., Marsiliea sp.(Pteridophyte) also provides conservatory for natural populations of two species of Equisetum i.e., Equisetum ramossisimum ssp.and Equisetum ramossisimum ssp.debile .
Plant diversity introduced
After preparing the area by grass and debris removal and soil filling and leveling planting initiated as per the layout plan. The Garden was provided with a bio-fencing of Carrisa carandus (Karonda) plantation on all the four sides. Till date more than 435 plant species have been introduced in the Botanical garden.
The Garden has been provided with a bio-fencing of Carrisa carandus (Karonda) on all the four sides. There is a boundary plantation around the Botanical Garden consisting of a mix of perennial shrubs, small and large trees. Except a few, all species are indigenous or endemics. The boundary plantation consists of a total of 84 plant species belonging to 37 plant families. Out of 84 plant species; 46 belong to large trees, 21 small trees and 17 shrub species. T A total of 469 plant species (including varieties) have been introduced in Thematic Botanic Garden. All these species belong to 110 plant families and 320 genera. The main thrust is to introduce as many as rare, endangered and threatened plant species in the Garden such as Commiphora weightii (Guggul), Saraca asoka, etc. from the conservation point of view.
Tree species: There are a total of 70 tree species in the Garden of which 47 species are part of the boundary plantation.
Small Trees and Shrubs:The Garden has 18 small or large shrub species planted in the boundary.
Layout plan of planting the boundary plants
In planting scheme a combination of large trees, small trees and shrubs was adopted for planting small trees and shrubs in between large trees of boundary plantation. The details are given in Annexure 1. The distance between larger trees is 7 m and in between there is a smaller tree. In between larger tree and smaller tree shrubs have been planted. It has been ensured that different trees flowering at different times of the year and of different colours are scattered all over the boundary .On wetland side boundary Salix tetrasperma and Salix babylonica plants have been planted at an espacement of 5 m.
Proposed Themes to be established in the Thematic Botanical Garden
The following eleven themes are proposed to be established in the Garden. Taxonomically identified plants of each theme will be collected from various research institutions and purchased from standard nurseries, wherever available and planted systematically in the four thematic genepool gardens. Emphasis will be to include as many as possible RET species in each theme.
Theme 1: Endemic and RET Species Garden
Theme 2: Fruit Plants Garden
Theme 3: Palm Garden (Palmetum)
Theme 4: Bambusetum (Bamboo Garden)
Theme 5: Medicinal Plants Garden (including, Anticancer , Antimalarial and Anti-Oxidant Plants)
Theme 6: Aquatic Plants Garden and Conservation Area
Theme 7: Arid and Semi-arid zone plants (Xerophytes) Garden
Theme 8: Cacti and Succulents Garden (Green House)
Theme 9: Cryptogams (Bryophytes and Fern & Allies) Garden
Theme 10: Gymnosperms Garden
Theme 11: Butterfly Garden
Theme Gardens being established
Of the 18 themes proposed the following eight Theme Gardens have been established in the Botanical Garden which include a total of 323 plant species (Fig. 27). Plants of various species under eight different themes such as Fruit Plants Garden (60 variety of plant species), Palm Garden (32 species), Gymnosperms Garden (29 species), Bamboos Garden (10 species), Medicinal Plants Garden (132 plant species), Xerophytes Garden (36 species), Hydrophytes Garden (16 species), Ficus Garden (14 species) were planted. Since, Gymnosperms and desert plants will be planted on a soil mound to give a feeling of a hill or sand dunes all the plants are maintained in large pots at respective places.
