Habitat loss and deterioration are two major causes of the global biodiversity crisis. The European Commission is committed to halt biodiversity loss in Europe, and created the Natura 2000 network [1], an ecological network consisting of thousands of protected sites that hold rare or threatened habitats and species. Furthermore, member states are required(More)
Natura 2000 habitats are priority habitats for nature conservation in Europe and need to be monitored closely. In this study, angular hyperspectral CHRIS/Proba imagery was tested for mapping a Natura 2000 heathland site in the north of Belgium. Two ensemble classifiers, Random Forest (RF) and Adaboost, were used and their results compared with Support(More)
Uncontrolled, large fires are a major threat to the biodiversity of protected heath landscapes. The severity of the fire is an important factor influencing vegetation recovery. We used airborne imaging spectroscopy data from the Airborne Prism Experiment (APEX) sensor to: (1) investigate which spectral regions and spectral indices perform best in(More)
Habitat monitoring of designated areas under the EU Habitats Directive requires every 6 years spatially explicit information on area, range, structure and function for the protected (Annex I) habitat types. Hyperspectral remote sensing could be an important technique to assist in the evaluation of the habitat conservation status by providing continuous maps(More)
Due to urbanization, conversion to forest or agricultural land, but also atmospheric changes, heathland areas in Western Eu-rope started to decline from the beginning of the 20th century [1]. As a result, many heathland sites, among which Kalmthoutse Heide in Belgium, were included in the European Natura 2000 program, a network of protected areas all across(More)
Straightforward mapping of detailed heathland habitat patches and their quality using remote sensing is hampered by (1) the intrinsic property of a high heterogeneity in habitat species composition (i.e. high intra-variability), and (2) the occurrence of the same species in multiple habitat types (i.e. low inter-variability). Mapping accuracy of detailed(More)
Natura 2000, an EU-wide network of nature protection areas, has as main objective the achievement or maintenance of a favorable conservation status of habitats protected by the EU Habitats directives. Within this framework, this study examines a strategy to characterize the status of heathland vegetation from airborne hyperspectral AHS data in the(More)
Monitoring and reporting on the status of Natura 2000 habitats is an obligation under the 1992 Habitats Directive for each member state of the European Union (EU). Satellite imagery providing up-to-date information for a large areal coverage could be an interesting source to complement conventional, but laborious, field-driven surveying methods. Quality of(More)
a r t i c l e i n f o Heathlands are man-made habitats and their decline during the last century can be contributed to shifts in both agricultural and management practices as well as to hydrological and atmospheric changes. As a result, many heathland sites, including the Kalmthoutse Heide in Belgium, were included in the European Natura 2000 program, a(More)
