Why are Botanical Gardens So Important to The World? – Top 5

Translated by Nick R

As you may already know, plants provide numerous medicinal, nutritional, ornamental, industrial, and environmental benefits. If you didn’t know it, you should check out our blog to learn about this and much more. However, a current problem has become evident: namely, the destruction of natural vegetation.

The reasons go from deforestation to fires that wipe out all kinds of life in their path. Botanical gardens have been created to reduce this damage, thus preserving the flora, which is a valuable natural resource.

For this reason, in this blog,  I want to explain the importance of botanical gardens, their functions, the benefits they offer, and finally: 5 amazing gardens that can be found in around the globe.

What are botanical gardens? 

A botanical garden is where a great variety of living plant species are found. Unlike other plant environments, in these centers, is held an order, control, identification, and documentation of plants. This facilitates their study and preservation.

In many of these gardens, threatened or endangered plants are protected, and species of high endemic value are reproduced. That is to say, species that only exist in the region where the garden is located and, therefore, are invaluable.

You should know that there are 2 methods used to preserve plant biodiversity.

The first method is in situ, or on-site and consists of looking after and protecting plants in their place of origin or natural habitat. These protected areas are developed, maintained, and researched.

The second one is called ex-situ, or off-site. And it consists of taking care of plants outside their natural habitat, known as captivity. This is where botanical gardens and even seed banks operate.

Importance of botanical gardens 

It’s also sought that all botanical gardens worldwide cooperate in order to exchange relevant information about the plants they house in their facilities. As I mentioned before, such places, besides preserving the plant resource, investigate every aspect of it in depth.

This is crucial since one of the gardens’ functions is to educate the population about plants. Specifically, about the importance of plants in the world, their characteristics, varieties, functions, uses, and others.

Thus, it promotes vegetative conservation by people and encourages crop cultivation, particularly in cities. Without plants, the air quality could be affected, the temperature could increase, and people’s quality of life could deteriorate, among many other negative aspects.

Although the objective is to preserve the plant heritage, not all botanical gardens have the same approach. For example, some botanical gardens focus on research, teaching, field expeditions, and conservation.

Others dedicate to study local flora only, such as the Kirstenbosch National Botanical Garden in South Africa. Also, some carry out relevant studies in various areas for reforestation and conservation.

Then there are those that offer courses in environmental education, gardening, and horticulture, such as the Tuluá Botanical Garden in Colombia. And finally, we find those responsible for caring for biological reserves and those dedicated to the preservation of species with potential economic significance.

Benefits of botanic gardens 

In addition to the importance that botanical gardens have on the planet, they also have a series of benefits that I’ll mention below.

  • Vegetation, particularly in cities, provides people with physical and psychological wellness.
  • Botanical gardens and green areas in the city maintain ecological balance.
  • They serve as an oasis or refuge for those pollinating animals such as bees, which are in danger of extinction.
  • They help raise people’s awareness of the importance of vegetation and its role in the ecosystem.
  • They contribute to tourism in cities with botanical gardens.
  • They house a large number of plant species from all over the world, which contributes to the preservation of these species.         

Functions of botanic gardens 

The functions of botanic gardens should have the following approaches:

  • Biodiversity, conservation and sustainability
  • Knowledge and innovation
  • Culture and heritage
  • Education, coexistence and life quality
  • Economic and social development
  • Integration, openness and connectivity

As there are several approaches to be covered by these centers, the work was synthesized into 3 main lines. These are conservation, environmental education and research.

Conservation is focused on maintaining living species collected in the gardens, either in the form of mature plants or seed banks. This last form has acquired great importance as it guarantees the preservation of the genetic diversity of the plants.

Seeds are stored in locations with ideal conditions, which works to prevent the total extinction of plant species. Unfortunately, however, not all seeds of all plants can be protected by this mechanism. Therefore, saving the grown plant is preferred.

Obviously, gardens must provide the right conditions for these plants to grow properly. If necessary, they would build shelters or greenhouses suited to each species.

As for environmental education, the aim is to create spaces in which garden visitors can acquire knowledge about plants, their natural habitat and their care.

Environmental education is addressed to the general population; however, it focuses on schools. It should be seen as a contribution to facing future environmental challenges.

In addition, this approach encourages people to love nature and take interest in its care. Each garden offers various recreational programs; such as tours of the facilities or courses to achieve this goal.

Finally, research is responsible for increasing scientific knowledge about the various plant species, mostly local. This way, there will be an abundant exchange of information with other gardens. Thus, there is the certainty of providing truthful information to the public.

It’s necessary to know in detail every biological, systematic, evolutionary, and origin aspect of the plants. This way, you can guarantee their preservation and the increment of more botanical research.
