A framework to estimate the contribution of weeds to the delivery of ecosystem (dis)services in agricultural landscapes

There is a pressing need for indicators and methods to quantify the provision of ecosystem services as a prerequisite to identify management options that optimize trade-offs between services. Arable weeds provide multiple services and are thus a good model to evaluate such trade–offs. This flora pro...
