1. Environmental conventions aim to protect ecosystem structures and
functions to provide goods and services for mankind. The degree of aquatic
ecosystem naturalness, or ecological status as it is defined in the Water
Framework Directive (WFD) of the European Union, is notionally linked to
supplies of ecosystem services. In practice these links have rarely been
documented or even investigated and, to justify conservation and
management objectives based on the status indicators, it is essential to
demonstrate their relationships to ecosystem functions and services. 2.
The WFD requires member states to classify their surface waters aiming to
achieve good ecological status of water bodies. However, an implicit
assumption of the WFD, that the ecosystem functions and services targeted
to be protected and maintained are related to the measured status, remains
uncertain. 3. Using a time-series dataset covering almost 50 years, we
examined the development of ecological status of eight sub-basins of a
large boreal lake in response to improved wastewater management and
decreasing pollution. We particularly evaluated whether the observed
descriptors of biodiversity, ecosystem functions and services were
associated with the judgements of ecological status, and hence if the
ecological status is a relevant proxy for ecosystem values to be
protected. 4. The ecological status of the polluted sub-basins responded
consistently to the decreased nutrient and organic loading. Temporal
trends in the biological quality elements and water quality were mostly
parallel and showed good status roughly simultaneously. Combined
ecological status also appeared to predict some features of taxon
diversity (profundal macroinvertebrate and phytoplankton richness),
ecosystem functions (primary and bacterial production) and ecosystem
services (fish catch and reproductive potential of coregonids). 5.
Synthesis and applications. We observed that some ecosystem service
supplies and taxon diversity increased with increasing ecological status
of the lake. Therefore, our results suggest that ecological status
estimates based on simple structural characters are relevant to the
ultimate management goals of maintaining biodiversity, ecosystem functions
and services, and hence might suffice for extensive assessment and
monitoring of lake ecosystems.
