It is crab grass.
Pioneer plants such as grasses, weeds, and fast-growing shrubs are usually the first to grow during secondary succession. These plants are able to quickly colonize disturbed areas and create the conditions for other plant species to establish themselves over time.
Soil nutrients remain in the area which enables plants to grow.
A tornado results in secondary succession. The plants on the surface are destroyed, but buried seeds generally stay in place and the soil remains mostly intact.
After a fire destroys a forest, secondary succession occurs where grasses and shrubs start to grow first, followed by small animals like rodents and insects. As these plants and animals establish, larger plants and animals such as trees and birds gradually return over time.
Secondary succession is faster than primary succession because soil is already there and the soil usually contains many seeds.
I takes longer for primary succession than secondary succession to go back to its original state
Secondary succesion is the succession that occurs after the initial succession has been disrupted, and some plants and animals still exist. It is usually faster than primary succession.
Pioneer plants are usually present in an area where primary succession begins.

Primary succession occurs on newly exposed surfaces with no soil, while secondary succession occurs in areas with existing soil that has been disturbed or altered. Primary succession starts with pioneer species that can survive harsh conditions, while secondary succession starts with species that can quickly colonize open areas.

A requirement for secondary succession to occur is the presence of existing soil and seeds or roots of plants that were present before the disturbance. This allows for the re-establishment of plant life in the area. Additionally, a lack of extreme environmental conditions, such as ongoing drought or severe pollution, is needed for secondary succession to take place effectively.
