„Cadastre Des Biotopes“ Evaluation of Open-Landscape Biotopes and Habitats in Luxembourg Control of Biotopes

„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 9 Evaluation 2016 927 Biotopes in 13 communes were evaluated respecting geographical representativity: • North: Troisvierges (301) • West: Ell (60), Beckerich (27) , Saeul (16), Hobscheid (73), Septfontaines (66) • Center: Mersch (126), Lintgen (30), Lorentzweiler (46) • East: Consdorf (21) • South: Pétange (38), Differdange (41), Dudelange (76) 10 Evaluation 2017 494 Biotopes in 12 Communes were evaluated respecting geographical representativity: • North: Rambrouch, Wiltz, « Eschweiler » • West: Kehlen, « Koerich » • Center: Walferdange, Steinsel, Kopstal • East: Rosport, Mompach • South: Esch/Alzette, Schifflange 11 Evaluation 2016 12 Evaluation 2016 13 Evaluation 2016 14 Evaluation 2016 15 Evaluation 2016 16 Quantitative balance Quantitative balance Nassbrachen, Quellsümpfe, Niedermoore… Sumpfdotterblumenwiesen Streuobstbestände Quellen/flächig Großseggenriede Glatthaferwiesen Hochstaudensäume Pfeifengraswiesen (Molinion-Bestände) Borstgrasrasen Kalk-Halbtrockenrasen Calluna-Heiden Eutrophe Stillgewässer mit Vegetation… -80% -60% -40% -20% 0% 20% 40% Zuwachs Verlust 17 Quantitative balance Balance (plus new Biotopes) Nassbrachen, Quellsümpfe, Niedermoore… Sumpfdotterblumenwiesen Streuobstbestände Quellen/flächig Großseggenriede Glatthaferwiesen Hochstaudensäume Pfeifengraswiesen (Molinion-Bestände) Borstgrasrasen Kalk-Halbtrockenrasen Calluna-Heiden Eutrophe Stillgewässer mit Vegetation… -80% -60% -40% -20% 0% 20% 40% Zuwachs Verlust 18 Qualitative evaluation Qualitative change (ha) 35,00 30,00 25,00 20,00 15,00 10,00 5,00 0,00 Unverändert Verbessert Verschlechtert 19 Dry Heaths (4030) 2.52ha evaluated QUANTITATIVE AND QUALITATIVE CHANGE FOR DRY HEATHS (= 13% of total national area) Verbesserter Zustand Unveränderter Zustand verschlechteter Zustand Fläche gewonnen Fläche Zerstört Modifikation Loss: 1.17ha (46%) 44% Main reason: scrub encroachment Modification: 1.11ha(44%) 9% 0% 0% Main reason: lack of mowing/grazing 0% CALLUNA - HEIDEN 46% - 20 Orchards (BK09) 7.83ha evaluated QUANTITATIVE AND QUALITATIVE CHANGE FOR ORCHARDS Verbesserter Zustand Unveränderter Zustand Loss: 1.3ha (17%) verschlechteter Zustand Fläche gewonnen Fläche Zerstört Modifikation 16% Degradation: 4.7ha (58%) 9% 2% Main reasons: lack of maintenance / 0% lack of replanting STREUOBSTBESTÄNDE 16% Amelioration: 0.7ha (9%) - 57% - 21 Semi-natural dry grasslands (6210) 23.68ha evaluated QUANTITATIVE AND QUALITATIVE CHANGE FOR DRY GRASSLANDS (11% of total national area) Verbesserter Zustand Unveränderter Zustand verschlechteter Zustand Fläche gewonnen Fläche Zerstört Modifikation Loss: 1.07ha (5%) 80% Degradation: 2.41ha (10%) Main reason: fertilisation...
