Stop 6 on the NUI Galway Biodiversity Trail is the lawn outside the Alice Perry Engineering Building where birds and pollinating insects can be found making use of flowers. Dr Gavin Collins (Microbiology) discusses the importance of microbes to the growth of clover plants. A map of the trail (although not necessary to complete the audio trail) can be found at http://www.nuigalway.ie/biodiversitytrail/
