Diversity of bees in burned and unburned praries in NW Minnesota

We collected data on bee diversity and abundance found in two recently burned restored prairies. The Long Lake site had four, one-hectare plots, two had been burned in 2013, and the other two in 2014. The Longspur-Ulen site was burned in 2013 and had two, one-hectare plots. Sampling was done by placing bee bowls 10 meters apart in two transects shaped in an X pattern within each one-hectare plot, and by morning and afternoon net sampling. A remnant prairie burned in 2010 was also sampled using the same techniques for comparison. Results of bee collections for the different burn age plots will be presented.
