General Site Description: 

This LTER-site corresponds with a 0.25 ha intensive forest monitoring plot (ICP Forests Level II) including a 0.25 ha buffer zone. The site is located in a homogeneous stand of Corsican pine (Pinus nigra ssp. laricio var. Corsicana Loud.) planted in 1930 on former heathland and is part of Gewestbos Ravels, a landscape (about 1000 ha) with deciduous and coniferous forests, heathland, bogs and pastures in the northern part of the Campine ecoregion of Flanders. The terrain is gently sloping (1-2 %) and the soil is a well-drained sandy soil (Endogleyic Folic Brunic Albic Arenosol (Dystric)). Ground vegetation is dominated by ferns (Dryopteris dilatata and D. carthusiana) and Vaccinium myrtillus. After a storm in February 2007 felled several trees an understorey of Betula pubescens started to develop. Intensive monitoring was started in 1987 with the main objective to study the effects of air pollution on biogeochemical cycling and forest performance (growth, vitality). This yielded a number of long-term data series including on atmospheric deposition, air quality, soil and soil solution chemistry, tree mineral nutrition, ground vegetation and growth. Monitoring will be continued in the future as a statutory task of INBO.

Purpose of Site : 

This site belongs to the network of the international cooperative programme (ICP Forests) operating under the UNECE Convention on Long-Range Transboundary Air Pollution (CLRTAP). The main objective is to study the effects of air pollution on forest condition with specific attention for ecosystem processes. More specific research objectives at the site are to evaluate trends in acidifying and eutrophicating deposition in relation to target loads and critical loads and to evaluate ecosystem response and ecosystem status based on trends in soil solution chemistry in relation to critical limits.
