What succession is a man-made secondary succession that occurs when a farmer stops cultivating their field for a lengthy period
harkovskaia [24]

The Old field succession is a man-made secondary succession that occurs when a farmer stops cultivating their field for a lengthy period of time.

The definition of old fields, which has been a topic of discussion among modern ecologists for some time, is that they are an intermediate stage in the natural succession of an ecosystem moving towards its climax community. Many times, old field sites are marginal lands with poor soil quality that are unfit for pasture or farming.

The terms "grass and forbs stage," "shrub and sapling stage," "pole stage," and "mature forest" are frequently used by foresters to describe these stages. Forest succession is the process by which plant communities develop in a regular, predictable manner.

When a farmer gives up on a farm, the abandoned land quickly becomes overgrown with weeds and grass.
