The DigiBog model simulates how peatlands develop over time. It looks at how plant litter is produced, peat decomposes, and peat's ability to hold water changes. By applying the model to different scenarios, researchers found that peatlands can grow into large domes, even with faster decomposition rates. The model also shows how peatlands can switch between wet and dry states, and how internal dynamics, not just climate, affect peat properties. In one case, a small peatland persisted near the edge due to internal feedbacks. Overall, the model helps us understand how peatlands evolve and how different factors influence their development.
