From landscape infrastructures to conservation biological control. Why the concept of functional diversity may be useful?

Landscape infrastructures are numerous. They can be hedgerows, woodlands or wildflower strips. They are known to provide ecosystem services such as reducing soil erosion and nutrient leaching or support biodiversity conservation. They may also help to biologically control pests. But conclusions of research papers are not unanimous about the positive effect of wildflower strips to control pests in fields. The cause may be the type of flower mixes sown in fields. In this context, the concept of functional diversity may be useful to constitute flower mixes that better enhance biological control.
