Permanent soil monitoring areas on forestry sites   (BDFSF)

It has long been known that soils alter more or less quickly with time. Some of these changes have natural causes, others are the result of soil contamination, caused either directly or indirectly by humans. They include load inputs from precipitation and particulates (acids, nutrients, heavy metals, radionuclides, organic pollutants, etc.), for example. However, as a result of cultivation and exploitation, agriculture and forestry have also altered soils since time immemorial. The vast majority of these processes are very slow and are barely perceptible to human senses.

In order to document any alterations, LBEG runs the Lower Saxony permanent soil monitoring programme. In cooperation with other state agencies, a network of what are referred to as permanent soil monitoring sites (Boden-Dauerbeobachtungsflächen - BDF), 90 in total, was established. Seventy are located on normal agricultural sites (BDF-L) and twenty on forestry sites (BDF-F).

Representative permanent soil monitoring sites (BDF) were selected using geoscientific criteria such as soil and rock relationships, climate and morphology. Moreover, LBEG took typical soil uses (agriculture and forestry, nature conservation areas) and stress factors (immissions, use-related stresses, etc.) into consideration.

The aim is to disclose any soil changes, based on these representatively selected monitoring sites, to evaluate causes and effects, and to predict future developments. If this can be achieved players in politics, administration and soil use will have a timely, reliable data basis to support their decision-making processes.

The BDF-F programme consists of a combination of feature and process documentation. Documentation of features includes the periodic identification of reserves and conditions using physical, chemical and biological soil investigations, surveys of biomass and its substance content, appraisal of forest conditions by crown inventories and needle/leaf analyses, as well as ground vegetation surveys. Processes are documented by measuring fluxes at and across the ecosystem boundaries.

In forest ecosystems deposition, release by weathering, take-up in biomass and removal by infiltrating water represent important fluxes for many elements. In addition, litter and physico-chemical environmental variables (immissions, meteorology) are also measured to appraise forest ecosystem stress situations (source: Nordwestdeutsche Forstliche Versuchsanstalt).

Similar programmes exist in other states; their scope is coordinated among the participating institutions. A corresponding European Union framework directive is in preparation.
