 There are three main techniques for measuring cover: Ocular or Visual Estimates, Line-Point Intercept, or Line Intercept. ​ There are three main techniques for measuring cover: Ocular or Visual Estimates, Line-Point Intercept, or Line Intercept. ​
  
-[[Line-Point Intercept]] is considered to be the least biased of all three. It is a rapid and accurate method for quantifying soil cover, which in addition to vegetation, includes cover by litter, rocks and biological soil crusts. Another similar method to line-point intercept is [[Step Point]], which is more rapid because no tape is required, but also more subjective.  ​+[[:​field_methods:​line_point_intercept|Line-Point Intercept]] is considered to be the least biased of all three.

 Line Intercept is separated into two main methods: [[Canopy Gap Intercept]],​ which measures the proportion of a line covered by large gaps between plant canopies and is an important indicator of the potential for wind erosion and weed invasion and [[Basal Gap Intercept]],​ which measures the proportion of the line covered by large gaps between plant bases and is important as an indicator of runoff and water erosion. ​   Line Intercept is separated into two main methods: [[Canopy Gap Intercept]],​ which measures the proportion of a line covered by large gaps between plant canopies and is an important indicator of the potential for wind erosion and weed invasion and [[Basal Gap Intercept]],​ which measures the proportion of the line covered by large gaps between plant bases and is important as an indicator of runoff and water erosion. ​
