COMFOR SUDOE Project

---

funded by EU program.

---

This repository has been build to share and store the script prepared along COMFOR SUDOE Project in the framework of Work Pakage 1 (Análisis, caracterización y clasificación de los bosques complejos del SUDOE) to analyse National Forest Inventory data and distinguis complex forest from non clomplex stands, i.e. plots which holds pluriespecific composition or with plurimodal composition in terms of total tree heigth and diameter at breast height.

The repository have 3 different folders containing scripts:

1. Scripts for preparing and loading data from Spanish National Forest Inventories
2. Scripts for selecting and calculating which plots belongs to each class
3. Scripts to make graphs and maps with the outputs
4. Scripts to build growth model for complex forest

Prepare Spanish NFI data into RData format files and load into R environment

This folder include scripts used to prepare RData files of released editions of NFI, and to load them into an R environment. The link to download RData files is also available.

Calculus for discriminate complex forest plots

• NFICalcFinal.r

This file read tree data from Spanish NFI database and select plots with multispecific composition and plots with multiestratified composition at height and dbh levels

input files:

• if_pcmayores2.csv tree database file

• if_plot2.csv plot dadabase file

• if_plot.coord.if3.csv plot position information

output files:

• of_plotsMonoSP.csv list of plots with monospecific composition

• of_plotsPluriSP.csv, of_plotsPluriSP_sps.csv list of plots with monospecific composition, the second with tph and basal area by species

• of_plot.ht.normality.csv, of_plot.dbh.normality.csv result of normality test (Shapiro–Wilk) for diameter and height distributions

• of_resultHeightPlurimodal.csv result of multimodality test for non-normal distributions for height

• of_resultDiamPlurimodal.csv result of multimodality test for non-normal distributions for diameter

Maps and graphs of NFI plots by clases of complexity

This folder holds scripts aiming to make graphical representation of all calculus made previously, including maps at diferent levels and plots of evolution along different editions of NFI.

There are also scripts for revise species composition, mixed species combinations, selection of plots with especific combinations and graphs of this combinations

• NFIComplexForMap.r

Growth model build example for a complex forest

With this scripts, a model growth of mixed plots including Chestnut and Oak has been prepared as an example.
