Thin trees within forests
A replicated, paired sites, controlled study in 2011–2012 in six oak/hornbeam forests in South Moravia, Czech Republic (Sebek et al 2015) found that partially-cleared plots had higher butterfly but lower moth species richness than plots of closed-canopy forest. Butterfly species richness was higher in partially-cleared forest plots connected to the forest edge (16) and naturally open forest plots (14) than partially-cleared plots >20 m from the edge (10), which in turn had higher richness than closed-canopy forest plots (2). However, whilst moth species richness was higher in partially-cleared forest plots connected to the edge (97) and naturally open forest plots (111) than partially-cleared plots >20 m from the edge (81), all three had lower richness than plots of closed-canopy forest (130). In February 2011 and 2012, four 40-m2 plots were established at six forest sites: a partial clearing at a forest edge connected to a meadow, a partial clearing >20 m from forest edges, closed-canopy forest, naturally open forest. A few trees were left in the two clearings to replicate open forest. In the May–September after plot establishment, adult butterflies were surveyed five times for seven minutes/plot, and moths were captured once/month using one light trap/plot.

Clear or open patches in forests
A replicated, paired sites, controlled study in 2011–2012 in six oak/hornbeam forests in South Moravia, Czech Republic (Sebek et al. 2015) found that partially-cleared plots had higher butterfly but lower moth species richness than plots of closed-canopy forest, and species richness of butterflies and moths was affected by distance of the plot to the woodland edge. Butterfly species richness was higher in partially-cleared forest plots connected to the forest edge (16) and naturally open forest plots (14) than partially-cleared plots >20 m from the edge (10), which in turn had higher richness than closed-canopy forest plots (2).
