Like human beings, plants are living beings that carry out their life processes on our planet: they are born, grow, reproduce and die. Like any living being, they have their right to inhabit our planet, Earth. In addition, plants play a very important role on Earth, without which, most likely, other living beings would not live, since they are essential to maintain natural balance. Among these functions is being a filter for pollution, controlling and moderating the earth’s temperature, producing part of the oxygen we breathe, controlling biogeochemical cycles, being a very important part of the food chain, or serving as a support and natural fertilizers for the soil. Plants are an important biological resource and of potential use for human societies,
However, current social development imposes activities that lead many plants to extinction. In this AgroCorrn article, we will talk about which plants are in danger of extinction and their causes .

Causes of the danger of extinction of plants and their extinctions
We can divide the causes of the danger of extinction and the extinctions of plants into two types: human and natural.
Endangered plants: human causes
Among human threats, we can highlight the destruction of habitats as the main cause. Within this, we include the expansion of urban areas, land in use for crops, deforestation of large areas (linked to agriculture, livestock, mining, construction …) or intentional forest fires.
Another major problem affecting plant species is the illegal or legal commercialization of species, in many cases linked to collectors who introduce them from other areas or linked to ornamental purposes. Phenomenon that often leads to the introduction of invasive plant species, something that also happens with invasive animal species , which frequently cause the elimination of native flora and other plant species, being a great ecological threat to vegetation.
Among the natural threats, one of the most important is the appearance of pests , whether they are plant diseases or insects that have a great and rapid expansion throughout the territory and that can destroy large plant populations in a short time. This can sometimes lead to the extinction of a plant species.
Another important threat is natural (unintentional) fires, such as a lightning strike, which can devastate large territories together with the populations that inhabit it. An important factor of fires is that they also deteriorate the substrate on which the plants grow, for a long time.
We can also cite other meteorological phenomena such as floods, earthquakes, tornadoes or climate warming, which can lead to the extinction of many plants by modifying their ecosystem. These meteorological phenomena arise many times by a combination of natural and human processes.
Examples of the causes of the danger of extinction of plants
An example of these causes of extinction is the plant trade can be observed in the desert of Chihuahua, Mexico. One of the richest areas in the world in cactus biodiversity, home to about 1,500 species. In recent years, this great wealth of cactus has been under threat of extinction due to its commercialization as an ornamental species or for other purposes.
The introduction of animal species also leads to the extinction of plants , an example of this occurs in the islands of Hawaii, where the introduction of herbivorous animals (natural predators of plants) has led to an extinction of almost 10% of the species of plants typical of the islands and endangered almost half.
An example of the threat of meteorological phenomena has taken place between 1999 and 2002 with a shrub that is only found in a very small space on the islands of Corsica and Sardinia, called Anchusa crispa. Many specimens of this shrub have died due to the fragmentation of their habitats and the storms that have displaced huge amounts of sand on their specimens.
Examples of plants in danger of extinction in Spain
Many people wonder what are the plant species that are in danger of extinction in Spain, since the mountains, mountains and even the coasts are increasingly affected by our activity and by some natural disasters.
Thus, these are some cases of plant species in danger of extinction in Spain :
- Sierra Nevada chamomile or royal chamomile ( Artemisia granatensis ): plant that grows 2,000 meters high in Sierra Nevada. Currently it is estimated that there are less than 2,000 specimens left, which is why it is classified as threatened.
- Silene del Peñón de Ifach ( Silene hifacensis ): a species with a very small population that lives in areas of Alicante and Ibiza.
- Pineapple de Mar ( Attraylis preauxiana ): species from certain areas of the Canary Islands with a habitat highly threatened by urban construction.
- Four-leaf clover ( Marsilea quadrifolia ): currently extinct in Spain, it still survives in different areas of Europe. It is an aquatic plant that lived in calm and clean waters, it became extinct due to the use of different agricultural products and eutrophication.
More names of endangered plants
Apart from the previously mentioned ones that are at risk in the area of Spain, here we mention many more names of plants in danger of extinction and of families or genera that are also at risk.
- Western Underground Orchid ( Rhizanthella gardneri )
- Venus flytrap ( Dionea flytrap )
- Attenborough pitcher plant (Nepenthes attenboroughii)
- Green jade flower (Strongylodon macrobotrys )
- Corpse flower ( Amorphophallus titanum )
- Baobab tree ( Adansonia digitata )
- Gran Canaria Dragon Tree ( Dracaena draco )
- Coral tree ( Erythrina )
- Clog orchid or lady’s shoe ( Cypripedium calceolus)
- Araucariceas Maple
- Welwitschia Mirabilis
- Apocynaceae or Aristoloquiceas Asclepiadceas
- Anacardiceas Apocinceas
- Sonowdonia Hawkweed
