COCONUT: Understanding effects of land use changes on ecosystems to halt loss of biodiversity – due to habitat destruction, fragmentation and degradation

Ingolf Steffan-Dewenter, Jochen Krauss

Funding: EU (FP 6)
Duration
: November 2006 – October 2008

Project
:
In the COCONUT project we studied time-delayed extinctions in vascular plants and butterflies on extensive grasslands in five European countries.  We showed that long-lived vascular plant species respond time delayed at a scale of 50 years after habitat loss, whereas short-lived butterflies did not show a time delay in extinctions (Krauss et al. 2010).

Study sites: Finland, Sweden, Estonia, Germany, Spain

Habitats: extensive grasslands

Species groups: Butterflies and vascular plants

Methods: Transect walks, quadrate sampling, GIS
