SIIMADER: Inifap Computer System to Management Stands Density

Abstract

Density management diagrams (DMD) are tools for diagnose the level of stand competence and for prescribing thinning programs. However, they are perceived as complex, so their acceptance and use is limited. To overcome this idea, DMDs are required to be scaled to an intuitive and interactive level to facilitate their practical use by foresters. The objective was to design and develop an online computer application (CA) that reproduces DMDs based on the Reineke and Yoda functions to provide operational and interactive functionality to users in the diagnosis and prescription of thinning as intermediate silvicultural treatments to management regular forests. The engineering, architecture, components, modules, catalogs and programming language of the CA were designed and defined, for this a participatory process was applied that involved: (1) intellectual part, by expert researchers with specialized knowledge in thinning; (2) users, identified as forestry technicians who conduct operational management when applying forestry; and (3) developers, by expert programmers. The CA developed was called SIIMADER, an acronym for "Inifap Computer System to Management Stands Density", which through algorithms executes routines to enter, process, store and output information in tabular and graphical form to manage density. The main output are thinning programs. The CA was generated in the Visual Studio® 2019 development environment, to program the algorithms the C # language was used, the database management system was Microsoft® SQL Server® Standard version 12.0. AI is operating online with free access and prior registration in a hosting with its own domain on the internet. SIIMADER is a computer science and technological innovation tool that will help to apply quantitative forestry and improve the growth of stands.
