Methods

Sampling methods: line transect, butterfly nets, baited, other traps, visual
Sample size: 457
Years: 2009 - 2011
Sampling comments: combination of trapping and Pollard walks: "eight randomly selected permanent line transects... were established 1.5 to 2.0 km apart from each other. The line transects were situated 500 m inside the forest from the edge to reduce β diversity and edge effects respectively. Four line transects were in logged or degraded forest (DF) and four were in unlogged or primary closed forests (CF)... 20 bait traps were hung at 200-m intervals along 4 km of transects at closed forest and degraded forest and sampled butterflies for 7 consecutive days on two occasions covering both winter and summer seasons... 280 trap days in total... In line transacts, the survey walked was performed along each transect at the speed of approximately 10 m per 10 min and recorded or collected all butterflies that were seen using butterfly swiping net in a belt of 10 m width in each side of the transect. All butterflies and habitats data were collected in point transects within 30 m radius"
