Summary/Abstract: The transport infrastructure is the significant factor affecting not only its immediate surroundings but also the landscape in the macroscopic scale due to the fragmentation and barrier effect. The original 'Impact of the road traffic on biodiversity atlas' was issued back in 2008 introducing maps of conflicts between green and transport infrastructure and evaluating the degree of landscape fragmentation. But a lot has changed since then. New motorways and expressways intersecting the landscape created new barriers, and the overall intensity of traffic increased. Therefore conditions for wildlife migration became worse. The opportunity to update this set of maps came with the publication of results from the National traffic census 2016. These maps are designed for the use of the strategic planning of transport sector due to the scale and the level of detail. The main purpose is to support the screening phase of the EIA process – to determine whether an area may be affected by traffic and which level of risk should be expected. Another usage is to compare the change over the past ten years by comparison of original and updated maps.
