What is the ecological succession on a bare plot of land?

This would be primary succession. The exact details will depend on where this bare plot is.

Primary succession for land newly exposed due to glacial retreat will look different than primary succession for land newly created by volcanic activity.

Ecological succession on a bare plot of land typically follows a sequence starting with pioneer species colonizing the area, followed by intermediate species, and ultimately leading to a climax community. The process can be categorized into primary succession, which occurs on newly formed land devoid of soil, and secondary succession, which occurs on previously inhabited land that has been disturbed or cleared. In primary succession, pioneer species such as lichens and mosses establish on bare rock or sand, gradually breaking down the substrate and facilitating soil formation. Over time, grasses, shrubs, and eventually trees colonize the area, leading to a diverse and stable ecosystem. Secondary succession begins on preexisting soil and occurs more rapidly as the soil already contains seeds, roots, and nutrients. The process generally follows a similar trajectory as primary succession, albeit with a shorter timeline due to the presence of established soil.

Ecological succession on a bare plot of land typically begins with pioneer species, such as lichens and mosses, colonizing the area. These species can tolerate harsh conditions and begin the process of soil formation. Over time, more complex plants like grasses and shrubs establish themselves, leading to a transition to a grassland or shrubland ecosystem. Eventually, as the soil develops further and conditions continue to change, trees and other woody plants take over, leading to the establishment of a forest ecosystem. This process of ecological succession continues until a stable climax community is reached, which is determined by factors such as climate, soil type, and disturbance regimes.
