Today about a third of world plant species face a threat of extinction due to devastating human activities that are contributing to the loss of plant diversity at a distressing rate contributing to the reduced ecosystem. The reduced plant cover we are facing in the world to is hugely contributed by our ferocious activities such as over-harvesting and over-exploitation, use of exotic plant specious, land-use change, urbanization, environmental pollution and other activities that are not environmentally conscious. Plant plays an integral role in humans, they are the source of oxygen, food, medicine and home to millions of animal species, therefore, we need to develop reliable methods of conserving them particularly the endangered plant species . Given the importance of plants to humans and high risks of some species becoming extinct both public and private institutions have stepped up their conservation measures which have contributed to the emergence of many botanic conservation gardens, these gardens play a key role in the protection of endangered plant species, provide data for scientific research, promote awareness and also of human purposes. There are a variety of reasons why plant botanic gardens have become popular today to learn more continue reading the article.
The primary importance of plant botanical gardens is to protect, conserve and diversify plant species particularly the endangered plant species, today there are an estimated 2500 plant botanical gardens worldwide with over 6 million accessions of living plants, this is a significant number of species and it is said to represent about a quarter of the world vascular plant species, this is important because it helps in conserving the endangered plant species and diversification of global plant biodiversity which counters plant lose contributed by human activities and climate changes.
The other role of botanical gardens is in scientific research, botanical gardens serve as a taxonomic research center, researchers also find plant botanical gardens important in providing valuable plant ecology data such as a phenological indication of climate change, collection of data that can help them assess plant-animal interactions, data relating to plant physiology among other important data. Because of the variety of species plant botanic conservation have it make them a good location for many researchers to study plant functional characteristics such as trade-offs between species traits and plant performance.
The vital role of plant botanic conservation is in the understanding of the threatened plant species, this is made possible by the huge presence of plant species in the botanic garden, botanic garden conservation contribute to the protection, maintenance, and support of threatened plant species mainly through ex-situ conservation which is mainly conservation of biological diversity from their natural habitat. Those are some main roles of botanic garden conservation but also important roles of these botanic gardens include spreading awareness to the public about threatened plant species and the need to protect the earth’s plant cover.
