The Oman Botanic Garden is a new world-class development of the Diwan of Royal Court in Oman, celebrating the unique plants, landscapes and cultural traditions of Oman. The garden is currently under construction and when it opens it will showcase all of the native plant species of Oman in a series of carefully created, naturalistic habitats from the dry deserts to the rich monsoon cloud forests. The garden will also showcase the traditionally cultivated crops and the many ways that people use plants in Oman. With this concept, the Oman Botanic Garden is unique in the world and of global significance – no other botanic garden is representing the entire flora of one country in habitat settings. It will present an unprecedented opportunity for visitors to experience the flora and vegetation of Oman while learning about the agricultural heritage, rich cultural traditions and legendary hospitality of the country. The design concept is based on four basic principles: * The native flora is represented in naturalistic habitats * The garden reflects and honours Oman’s rich botanical heritage * The garden demonstrates a sustainable approach * The displays are interactive and apply a modern and exciting way of education and interpretation Situated in Al Khoudh, about 20 kilometers from the capital Muscat, the Oman Botanic Garden is being developed on 423 hectares. This is an ambitious project and is the first of its kind in the Sultanate of Oman and in the whole region. The garden will be the largest botanic garden in the Arabian Peninsula and one of the largest in the world. The garden will consist of the following key components: nursery, visitor center, research center, field study center, outdoor habitat gardens, northern mountain biome, southern mountain biome, and nature reserve area. The Oman Botanic Garden project is built upon a foundation of environmental sensitivity and sustainability. All aspects of the project must support this approach. The project is being built within the limits of a large nature reserve, and as such a “tread lightly” approach must be followed, both in concept and in construction. As a part of its main objective, Oman Botanic Garden is helping to create a more sustainable world, throughout its design, construction and operation. The project is applying for certification for some of the buildings through the Leadership in Energy and Environmental Design (LEED), operated by the US Green Building Council. This places stringent criteria on energy efficiency, sourcing and use of materials, minimising the use of resources and communicating best practice. Vision and Mission of Oman Botanic Garden Vision To inspire people, to conserve and cherish the biodiversity and botanical heritage of Oman for a sustainable future. Mission Discover, cultivate, showcase and protect Oman’s unique plant diversity and ethnobotany through innovative research, exciting displays and engaging communication. The Flora and Vegetation of Oman The Sultanate of Oman in the southern Arabian Peninsula is mainly characterised by arid habitats, with much of the region occupied by sand dunes or rock and gravel desert. However, and often in stark contrast to the deserts, the country also contains a seasonal cloud forest, open juniper woodlands and other habitats supporting high species diversity with many endemic plants. Oman lies in the transition zone between the Holarctic and Palaeotropical kingdoms, as well as between subtropical and tropical climate zones. This position is reflected by the presence of plant species from several biogeographical regions as demonstrated by the comparatively high number of vascular plants in Oman. A period of intensified botanical research in Oman has taken place over the last two decades. There has been good progress extending our knowledge of the flora of Oman, resulting in the description of 103 new range-restricted species since 1980 and the documentation of new records for the country (Patzelt, 2014). However, detailed studies of the vegetation and plant communities are still scarce and current knowledge ranges from no documentation at all to brief descriptions of the vegetation types or to characterisation of the vegetation units by their complete floristic composition and arranged in a hierarchical system of floristic similarity. Data are also lacking regarding the population parameters and ecology of individual plant species. Oman has a total of 191 range-restricted species, representing 13.6 % of the total flora (Patzelt, 2014). This high proportion of range-restricted species (endemics, near endemics and regional endemics) in the Sultanate can be explained by a unique combination of ecological factors that restricted the range of species in the past. Endemics are found in all vegetation types throughout the country. However, some habitats are particularly rich in range-restricted species and are of special interest, encompassing sites of maximum biodiversity. Significant species-rich habitats include the monsoon-affected mountains in southern Oman, the northern Hajar mountains, and the coastal areas of the central desert; these areas represent local centres of plant endemism. History and Development of Oman Botanic Garden Following a Royal Decree in 2006 by His Majesty Sultan Qaboos Bin Said, the Oman Botanic Garden project was initiated. The scale and complexity of the project is such that the design and construction work has been divided into multiple phases. Construction of the Oman Botanic Garden started in 2007 with the construction of a native plants nursery on site. The on-site nursery was constructed in 2008 and has been fully functional since then. The nursery now houses one of the largest documented collections of Arabian plants in the world, with ca. 70,000 plants in cultivation. The garden also houses a seed bank with currently ca. 5 million seeds. Most seeds are collected from the wild, with verification levels close to 100%. Many of the architectural, landscape architectural and infrastructure components of Oman Botanic Garden are currently under design or construction, at varying levels of completion, while the plant collection is being grown. The Oman Botanic Garden is not only Oman’s leading institution of National Plant Collections, but is already regarded as one of the world’s most interesting botanic gardens. Oman Botanic Garden Staff The current staff structure consists of five departments: Botany and Conservation, Living Collections, Education and Communication, Operations, and Corporate Services. To date, the garden employs 80 staff, including four international experts and 76 Omani nationals. Several of the team are recruits from the local village, enabling the involvement of the local community with the project and helping to ensure that the benefits and information about the project are shared - an important aspect of the project’s sustainability focus. Plants Collections in Oman Botanic Garden The plant collections of the Oman Botanic Garden include living plants in the nursery, seeds in the seed bank and preserved plants in the herbarium. The plants currently grown in the nursery represent the largest scientific and documented collection of Arabian Plants on earth. Only very few of the plants of Oman have been propagated or cultivated before, so the work of the nursery is greatly increasing the knowledge and understanding of the country’s flora. The Oman Botanic Garden botanist and horticulture teams collect plants as seeds and cuttings through regular field trips; hundreds of expeditions have taken placeto all areas and habitats of the country to collect, monitor and record invaluable data about Oman’s plants and habitats. The majority of the native plants of Oman which will be planted in the Oman Botanic Garden are not available commercially. Therefore, the botany team has spent thousands of days on field expeditions to collect seed and other plant material to build up the collection. Seeds are collected and the plants are propagated for the first time ever at the Oman Botanic Garden nursery. The overall vision of the habitat gardens is to represent a specific habitat at its best. A habitat design is not a formal design, but rather provides a true representation of the plants in their natural environments. The native plants of Oman will also be used in the amenity areas of the garden, outside of the habitats, to showcase the design potential of using native Omani plants in the landscape. Research in Oman Botanic Garden Oman Botanic Garden conducts active research in the areas of flora and vegetation of Oman, propagation and cultivation of native plant species, ethnobotany, plant pests and diseases, and designing with native species. The garden helps to protect the plant diversity of Oman through botanical and horticultural research and conservation. The Oman Botanic Garden Herbarium currently 1800 holds plant vouchers, which are arranged systematically. The herbarium is open to visitors. The garden will also conduct plant genetics research once the research facilities are constructed and ready to use. The Oman Botanic Garden will form a key part of Oman’s response to the Global Strategy for Plant Conservation, part of the Convention on Biological Diversity. Education and Communication in Oman Botanic Garden Environmental education is at the heart of the garden and one of its key functions. Through the work of the Oman Botanic Gardens, visitors will be encouraged to respect and care for the country’s indigenous natural environment and learn more about the fascinating cultural connection that exists between plants and people and value all that Oman stands for. Oman Botanic Garden currently develops tests and runs school programmes, programmes for university students, and for other visitor groups. Course material is being developed and further refined. The garden works together with the relevant Ministries, to ensure that the programme of the garden ties in the country’s curricula. A temporary visitor centre is used for pre-booked visiting groups and school parties. The garden’s website can be accessed at www.omanbotanicgarden.com. Global Botanic Garden Context There are currently 2,200 Botanic Gardens known in the world in nearly 150 countries, but there are very few in the Middle East and South-West Asia, although the area is home to an estimated 60,000 plant species. The flora of the Arabian Peninsula has so far been poorly represented in any botanic garden on a global scale. Botanic Gardens worldwide do not adequately reflect the Arabian plant diversity and number of collections is the smallest of all botanic garden living plant material. Oman has a rich and unique botanical heritage and has taken regional leadership in environmental issues. The garden will be the first in the world to grow only the native species of a region, planted in scientifically accurate, natural habitat gardens. The respect and value for plant diversity conservation fostered by the Oman Botanic Garden represents a major global step forward in global plant conservation efforts.
