A botanical garden is a landscaped place intended for the presentation of species and plant varieties.
Botanical gardens have three main objectives:
• The first and best known is a recreational goal . Exhibitions, plant sales, picnicking under the trees, bird watching and relaxation in a natural environment are all possibilities that gardens offer to city dwellers and tourists alike.
• The second, and very important goal of botanical gardens, is educational . It includes summer camps for young people, school visits, interpretation trails, classes and seminars, as well as publications and all the means for sharing information between botanic gardens and health professionals. horticulture and botany.
• Finally, gardens have a scientific purpose . Gardens have always been involved in the study of botany, taxonomy and systematics. Today, the fields of study are becoming larger, ranging from molecular laboratory research to field work in ecology. Emphasis should also be placed on the conservation and study of local vegetation.
All the species presented are cultivated and studied to satisfy several objectives:
a)to preserve in artificial conditions collections of living plants (especially rare and endangered species) and other botanical objects of great scientific, educational, economic and cultural importance;
b) carrying out scientific research work corresponding to the objectives of the botanical garden or dendrological park;
c) conducting educational and pedagogical and scientific-educational work in the field of botany and nature protection, plant breeding and selection, decorative gardening and landscape architecture.
Scientific research in state botanical gardens and dendrological parks is conducted in the following areas:
a) organization of special expositions, collection and experimental sites, nurseries, herbaria, auxiliary laboratories;
b) organization of expeditions and participation in expeditions of other institutions for the purpose of studying and mobilizing plant resources and replenishing collection funds;
c) the creation of seed funds, the exchange of seeds and living plants with various institutions and organizations;
d) primary cultivation, selection and reproduction of new economically valuable plants of natural flora and introduced cultural plants for their introduction into the national economy;
e) development of scientific bases and methods for protecting introduced plants from pests and diseases;
f) development of scientific bases of decorative gardening and landscape architecture;
g) holding scientific conferences and meetings;
h) publication in the established order of scientific works, popular scientific literature, catalogs of plant seeds, guidebooks and other works related to scientific research and popularization of the activities of state botanical gardens and dendrology parks.
The obvious role of botanic gardens for the conservation of biodiversity is ex situ conservation. Ex situ conservation, that is, the cultivation of wild plants out of their environment, has several advantages, Botanical gardens are the ideal place to practice ex situ conservation because of their proper facilities and competent staff in botany and horticulture. Ex situ conservation includes, of course, greenhouse or garden plant cultivation, but it also includes the maintenance of seed, pollen samples and cell and tissue cultures in vitro
One of the main objectives of a botanical garden for conservation may be to work on the conservation of its local flora . Actions in this direction range from scientific research to collaboration with municipalities and local organizations for the conservation or restoration of habitats. This collaboration of gardens with other organizations plays an important role in the implementation of national or regional conservation plans.
Achieving these goals requires first and foremost knowledge of biodiversity. Botanical gardens have since their inception been involved in documentation of wild and horticultural plants from around the world. Today, this role is increasingly broadened to include research into not only the plant species but also the ecosystems in which they live.
