„Cadastre des biotopes“ Evaluation of open-landscape biotopes and habitats in Luxembourg Control of Biotopes
Regular controls / checks of the mapped biotopes and habitats by the nature & forestry agents of the ANF • No botanical inventory
2 Re-evaluation of Biotopes
Aim of the project: • Re-evaluation of open-landscape biotopes and habitats mapped in 2007-2012 • Measure the evolution of conservation status of formerly mapped and evaluated biotopes and habitats • Assess the conservation status for the “Reporting” obligations for the “nature” directives.
Project duration foreseen over a period of 6 Years (2016-2022) and later… Representative random sample of 5042 biotopes to be re- evaluated
3 Methodology
Using the same mapping protocols & methodology
4 Methodology
5 Methodology
Assessing both quantitative and qualitative aspects of change of biotopes: • Improvement • Degradation • Extension • Reduction / Destruction • Modification Scanning for not yet mapped biotopes
6 Methodology
Qualitative change • Improvement • Degradation
Change can appear for entire biotope or for a part of the biotope
7 Methodology
Quantitative change • Extension due to favourable conditions • Loss/Destruction (can appear for entire biotope or for a part of the biotope)
8 Methodology
No change
Modification of biotope or habitat type is possible • Modification due to practice or environmental change
New biotopes can be assessed • either overlooked at first monitoring or appeared in the course of last years
