Tornadoes cause secondary succession. They destroy vegetation but leave most of the soil and some seeds in place.
Generally secondary succession will take place. Since even though much of the vegetation may be destroyed the soil and some buried seeds mostly remain in place.

by formation of soil such as mushrooms and lichens

Primary Succession- The process of succession that begins in a place previously with out plants or soil . Secondary Succession- Succession that begins in a place that already once was home of living organisms.

Primary succession occurs in an area with no soil or organic matter, like an area after a volcanic eruption. Secondary succession occurs where there is already soil.
Primary succession happens in a place where there is no soil and as a gradual growth of an ecosystem over a long period of time. Secondary succession occurs where there is already vegetation but has been destroyed by a natural disaster.
Secondary succession is faster than primary succession because soil is already there and the soil usually contains many seeds.

secondary succession
Things in nature are not black and white, and there are intermediate stages so this makes this question somewhat difficult.Succession that begins in new habitats, uninfluenced by preexisting communities is called primary succession, whereas succession that follows disruption of a preexisting community is called secondary succession.Primary succession: the development of plant and animal life in an area without topsoil; the development of biotic communities in a previously uninhabited and barren habitat with little or no soil.Pioneer succession doesn't exist as a succession term, but pioneer species do.The definition of primary succession fits as the answer to your question.

Primary plant succession is the first stage of succession. Primary succession takes place on land and soil that has undergone a disturbance, eg after a mud slide, fires etc. Primary succession usually involves basic plant life and fungi colonising the disturbed area. These plants tend to be first of all mosses and lichens followed by grasses and small flowering plants. Primary succession over time will provide the soil with more nutrients and will increase the organic horizon layer of soil allowing secondary succession (bushes and larger plants dependant on more nutrients and soil) to commence.
