FEN Technology LLC has developed a digital predictive tool for forestry management that helps forecast the evolution of forests under a series of key environmental parameter changes. The Forest Inventory Management System (FIMS) uses Lidendenmayer computational algorithms to model changes in the parameters of trees. Aerial imagery and field data source the algorithm to model branches development and species spatial distribution changes, which in turn help plan urban tree plantation, reforestation, pruning and wildfire prevention strategies. FIMS is coupled with a novel agent-based approach to include the effects of external factors such as topography, sunlight intensity, wind trends, climate change, pests and disease, wildlife and infrastructures. The FIMS is designed to help managing forests by city councils, government and the wood industry.
