Glebe Lane Pastures is a Local Nature Reserve, Borough Grade I, in Arkley in the London Borough of Barnet. It consists of five fields off Glebe Lane, some managed for hay while others are grazed by horses. It contains flower-rich unimproved grassland which is dominated by Yorkshire Fog, with a good variety of other grasses. Tufted hair-grass is dominant in damper areas, and ditches contain a rich wetland vegetation. The fields are separated by hedges of hawthorn, blackthorn and crab apple. The site is private, and can only be viewed from Barnet Road east of Glebe Lane.
