Key messages

One replicated trial in Maryland, USA found more bee species under power lines managed as scrub than in equivalent areas of annually mown grassland.

 

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. Power line rights-of-way are unfarmed and provide potentially valuable linear strips of habitat for bees and other wildlife. In the USA, they are periodically cleared of vegetation by mowing and/or herbicide treatment. A more cost-effective management method involves removing trees and other tall vegetation, mechanically and with selective herbicides, but retaining a dense scrub. One replicated trial under eight power line strips on a Wildlife Refuge in Maryland, USA (Russell et al. 2005) found significantly more bee species under power lines managed this way (32.5 bee species/site on average) than in equivalent areas of annually mown grassland on the Refuge, representing conventional power line management (23.2 species/site). There was no significant difference between power line scrub and mown grassland in the abundance of bees.
