Habitat plots are typically carried out at a minimum of 60 random locations on the two most dominant habitats of a site. The idea is to get a snapshot of the grazing pressure on the site, and to discover any trends that may indicate and increase or decrease in habitat quality. Each plot requires surveyors to examine a 2 m x 2 m quadrat which is then split into 50 cm2 subsections. The result is something like this:
The question is, how do you cart around 20+ metres of string without getting in a tangled mess?
