DENDROLOGY

Detailed explanation-1: -Abandoned cropland means that it was an inhabitant to some earlier species, but due to some reasons, the species vanished. Thus, it is an example of secondary succession.

Detailed explanation-2: -Secondary succession-Succession where natural communities develop in an area that was earlier occupied by living organisms that were somehow lost. It begins in areas where natural biotic communities have been destroyed such as in abandoned farm lands, deforested lands, flooded lands, burned forests, etc.

Detailed explanation-3: -When an abandoned field remains unused by humans for an extended period of time, it starts to undergo natural succession. Natural succession is the change in the species structure, both flora and fauna, of an ecological community over time.
