Every forest patch contains information on its perimeter, size, shape, and core area. By looking at all forest patches together, an impression can be gained of the fragmentation of the forest in the Paraguayan Chaco. Proximity is a measure of fragmentation. Areas of large and close by forest patches show high proximity values while isolated patches or patchest hat are only surrounded by small forest patches, have a small proximity. The Core area index quantifies the share of core area in the entire forest patch area. Thereby, corea area is the area of a forest patch with at least 500m distance to the edge of the forest. The Shape index is calculated from perimeter and area of a patch. The fragementation of a forest often has the effect that the ratio between area and perimeter is affected. The edge lengths become longer while the surface area becomes smaller. This data set shows how the fragmentation of the forest in the Paraguayan Chaco proceeded over the last two decades (2000 – 2020).

Fragmentation of forest cover in the Paraguayan Chaco 2000, 2010, 2020 - Processing Data: The forest cover shape file for the years 2000, 2010, and 2020 was derived from the forest masks of the respective years, which are a product of the Geo-ForPy project. More information on this data set can be found under the following link. Processing: The forest masks were transformed from a raster to a vector format using a 4 neighborhood and all forest patches less than 10 hectars were deleted. Next, patch level metrics (area, perimeter, perimeter-area-ratio, shape index, fractal dimension, proximity, core area, core area index) were calculated. Quality Assurance: The underlying forest masks have overall accuracies between 85% and 97%. Missclassifications directly affect the calculated forest area.
