Pioneer species

The "pioneer" species of plants are hardy and adaptable without special needs, they have the ungrateful task of colonizing an inhospitable physical environment.These plants practise a modifying action on the environment, making the soil more adaptable to other species that will settle subsequently. An ecosystem is neither static nor immutable, but in a continuous evolution, because of the bodies and plant species that live in it. The evolution of the ecosystem is called ecological succession and can be primary and secondary.
The first concerns the colonization of uncultivated land, the second is related to what happens in a neglected production environment.An example of primary succession is explained by what occurs in areas adjacent to active volcanoes after the eruption: after the lava has cooled, the soil is completely lacking of vegetation, then the first inhabitants appear, these are the lichens that begin the colonization of the lava layer.As they die, a substrate grows which will begin to develop first ferns and the simplest grasses that, in turn, will be a light and continuous layer of vegetation, which will produce the organic substance needed for the colonization of soil by shrubs and other plants with well developed roots.Then you get to the agricultural use of the land. The primary natural sequences, the pioneering organisms are always together with climatic factors what slowly changes the conditions of the soil to make it suitable for colonization by more demanding species.
