Title: PiroPinus version 2.0 /
Language: English
Description: PiroPinus is a prescribed burning guide for maritime pine (Pinus pinaster) stands in the form of a spreadsheet, conceived for operational use in the planning and evaluation of hazard reduction burns in natural fuels, i.e. slash from pruning or thinning is not present. It can also be used as a research tool for fire modelling purposes. Potential users are urged to try the guide in other medium- to long-needled pines (P. pinea, P. canariensis, P. radiata, P. nigra, P. halepensis), especially when the understorey is composed of Mediterranean-type species. PiroPinus is a all-in-one user-friendly tool that integrates models based on observed, real-world, fire behaviour and effects. Unlike other available tools, PiroPinus has the ability to: 1. Reflect local stand and fuel conditions in the output; 2. Assess the likelihood of sustained fire spread and quantify marginal burning conditions. Fire modelling systems using properly developed custom fuel models can be used to obtain accurate estimates of fire behaviour. However, such systems perform poorly at the high-end of the moisture content range and are not able to produce site-specific estimates. PiroPinus is composed of several interrelated or stand-alone worksheets for distinct objectives: (1) FUEL. Data entry of basic fuel and stand descriptors to assess fuel load and fire behaviour and effects; (2) RX WIN. Prescription window (general burning conditions); (3) RX DEV. Prescription development, the definition of burning conditions to avoid undesired fire impacts on trees and the forest floor; (4) MOIST. Fuel moisture content, to estimate the moisture contents of surface fine dead fuels and decomposing litter; (5) FIRE. Ignition and fire behaviour, to assess the likelihood of fire spread and quantify fire characteristics; (6) IGN PLAN. Assessment and optimization of area treatment rate; (7) TREES. Fire impact on trees, to assess canopy damage and mortality; (8) FUEL DYN. Fuel dynamics, to estimate fuel consumption and post-burn accumulation; (9) POST-FIRE. Post-burn assessment of fire behaviour and effects; (10) WEATH. Wind speed estimation and Canadian Forest Fire Danger Rating System (for regional planning).
