# Workflow: forest fragmentation
The forest fragmentation analysis, currently being conducted as a pilot project, holds the promise of setting a precedent
for future applications not only within individual member states but also on a larger European Union scale.
This initiative explores the feasibility and benefits of addressing forest fragmentation challenges, laying
the foundation for potential broader, EU-wide efforts to enhance forest conservation and connectivity.
# Forest Fragmentation Analysis Workflow
## Introduction
This document outlines the comprehensive workflow for forest fragmentation analysis, incorporating various scripts and methodologies to process spatial data effectively.
### Rationale:
Forests are crucial ecosystems that provide a wide range of environmental, ecological, and economic benefits.
However, they are increasingly threatened by fragmentation, which occurs when large forested areas are divided
into smaller, isolated patches. Fragmentation can lead to habitat loss, biodiversity decline, and reduced
ecosystem services. Recognizing the importance of preserving and restoring forest connectivity, this analysis aims to:
## Rationale
The analysis is crucial to understand the impact of environmental changes on forest ecosystems, providing insights into the areas of fragmentation and potential conservation strategies.
- Assess the extent and severity of forest fragmentation within specific regions or countries.
- Identify key drivers and factors contributing to forest fragmentation.
- Evaluate the impact of fragmentation on biodiversity, ecosystem health, and socio-economic aspects.
- Provide valuable insights for policymakers, conservationists, and land managers to make informed decisions regarding forest management and conservation.
## Goal
To assess forest fragmentation by transforming spatial data into actionable insights through advanced geospatial analysis.
## Workflow Steps
1. **Convert Shapefile to Raster Tiles (Resolution 5m per Pixel)**
- Load shapefile to PostgreSQL.
- Create raster tiles, mask, and fragmentation:
- [Rasterize Fragmentation 5m Script](https://github.com/E-O-Conchas/fragmentation/blob/main/1.rasterize_mask_and_fragmentation_5m.py)
- Combine mask and fragmentation:
- [Combine Frag Mask Tiles Script](https://github.com/E-O-Conchas/fragmentation/blob/main/2.combine_mask_and_fragmentation_tiles_gdal.py)
- Generate list of valid tiles:
- [Get Valid Tiles Script](https://github.com/E-O-Conchas/fragmentation/blob/main/3.generate_list_valid_tiles.py)
- Create VRT from valid tiles:
- [Create VRT Script](https://github.com/E-O-Conchas/fragmentation/blob/main/4.create_vrt_from_valid_tiles.py)
### Goal:
The primary goal of the forest fragmentation analysis is to inform evidence-based decision-making and policy
formulation in the context of forest conservation and connectivity. Specifically, the goals include:
2. **Tile Raster Inside GRASS GIS, run Clumps analysis and Export**
- Load VRT to GRASS GIS
- [Import tiles to GRASS GIS](https://github.com/E-O-Conchas/fragmentation/blob/main/5.load_vrt_to_grass.py)
- To develop a comprehensive understanding of the current state of forest fragmentation in the selected regions or countries.
- To create a foundation for future research and conservation efforts aimed at mitigating the effects of forest fragmentation.
- To raise awareness among stakeholders about the importance of maintaining and enhancing forest connectivity.
- To contribute valuable data and insights that can guide sustainable land-use planning and forest management practices.
- Run Clump Function on Full Raster
- [Clumps Full Raster and Report in GRASS Script](https://github.com/E-O-Conchas/fragmentation/blob/main/6.clumps_full_raster_and_report_GRASS.py)
- Tile Raster and Export Files in GRASS GIS
- Before Export Tiles, create a Mask to export only forest polygons
- [Create Tiles and Export Files in GRASS Script](https://github.com/E-O-Conchas/fragmentation/blob/main/7.create_tiles_and_export_files_GRASS.py)
3. **Delete Empty Tiles**
- [Delete Empty Tiles Script](https://github.com/E-O-Conchas/fragmentation/blob/main/8.delete_empty_tiles.py)
### Steps:
1. convert shape file to raster tiles (resolution 5m per pixel)
1. load shape file to postgreSQL
2. create raster tiles, mask and fragmentation using:
3. combining mask and fragmentation with:
4. **Aggregate Rasters to 1km Resolution**
- [Aggregate Tiles 5m to 1k Script](https://github.com/E-O-Conchas/fragmentation/blob/main/9.tiles_to_1km_optimized.py)
### Notes:
5. **Calculate Fragmentation Per Pixel with a Moving Window**
- [Calculate Fragmentation Index Script](https://github.com/E-O-Conchas/fragmentation/blob/main/10.fragmentation_indicatior_cal.py)
6. **Create VRT from the results **
- [Generate VRT file with the fragmentation results](https://github.com/E-O-Conchas/fragmentation/blob/main/11.convert_result_to_vrt.py)
