Answer
Human activity often interrupts the natural processes of succession. For instance, in heather moorland, human-induced factors prevent the ecosystem from reaching a true climatic climax.

Answer
Historically, the natural vegetation in heather moorland has been removed for agricultural purposes, particularly by early settlers. This deforestation has significantly altered the landscape, restricting the natural growth of vegetation.

Answer
The high rainfall and strong winds in the area have exacerbated soil erosion, resulting in a loss of nutrients essential for supporting further plant communities. This disrupts the trajectory of ecological succession.

Answer
Additionally, controlled burning, which usually occurs on a 10–15 year rotation, is practiced to prevent succession. While it does contribute to habitat management, it ultimately limits the environment from progressing towards a climactic community.
