Protect greenfield sites or undeveloped land in urban areas
A replicated, site comparison study in 2002–2003 in 39 tropical rainforest reserves, forest fragments and urban parks in Singapore (Koh & Sodhi 2004) found that protected primary or secondary forest reserves had a higher species richness of butterflies than forest fragments or urban parks. In protected forest reserves, the species richness of butterflies (8–27 species) was higher than in forest fragments (1–12 species) or urban parks (3–16 species). Forest reserves also had more unique, forest dependent, or specialist species than urban parks (data presented as model results). Four forest reserves (54–1,147 ha) consisted of old secondary and primary lowland tropical rainforest and freshwater swamp forest. Fourteen forest fragments (2–73 ha) contained patches of abandoned plantation and degraded secondary forest. Twenty-one urban parks (1–53 ha) were land that had been cleared, revegetated and maintained with a mix of native and non-native plants. From June 2002–June 2003, butterflies (excluding blues (Lycaenidae) and skippers (Hesperiidae)) were surveyed three times along one to fourteen 100-m transects/site.

Legally protect habitat
A replicated, site comparison study in 2002–2003 in four tropical rainforest reserves and 14 unprotected forest fragments in Singapore (Koh & Sodhi 2004) found that protected primary or secondary forest reserves had a higher species richness of butterflies than unprotected forest fragments. In protected forest reserves, the species richness of butterflies (8–27 species) was higher than in unprotected forest fragments (1–12 species). Protected forest reserves also had more unique species than unprotected forest fragments (data presented as model results). Four protected forest reserves (54–1,147 ha) consisted of old secondary and primary lowland tropical rainforest and freshwater swamp forest. Fourteen unprotected forest fragments (2–73 ha) contained patches of abandoned plantation and degraded secondary forest. From June 2002–June 2003, butterflies (excluding blues (Lycaenidae) and skippers (Hesperiidae)) were surveyed three times along one to fourteen 100-m transects/site.
