Provide nest boxes for stingless bees
Antonini & Martins (2003) erected 40 nest boxes (25 x 25 x 40 cm) for stingless bees on tree branches 3-5 m above ground, in pristine and degraded cerrado (grass/shrubland) in Minas Gerais, Brazil, in March 1999. None were occupied by any stingless bee colonies, although 48 natural nests were found in the 18 km2 study area. The lack of nest box uptake was thought to be due to an abundance of natural nest sites.
Legally protect large native trees
The cerrado tree Caryocar brasiliense is the only tree species protected by federal regulations in Brazil. A detailed study of nest sites used by the stingless bee species Melipona quadrifasciata in 18 km2 of degraded cerrado (72 plots, each 500 m2) in Minas Gerais, Brazil, found that they almost exclusively nested in C. brasiliense (Antonini & Martins 2003). Forty-six out of 48 nests were found in that species, although there were 55 tree species at the site. The authors argue that M. quadrifasciata is only found in the area because of the protection of C. brasiliense.
