In the Arctic plants are often associated with other plants in specific and recognizable units called "communities". These communities are often a function of slope, aspect, soil type and numerous other factors and are important in the study of plants, animals, and people of the Arctic. We will spend the first portion of the seminar defining plant communities, reasons for studying them and present several techniques used to sample vegetation. The techniques we will present are the Buchner sampler, point frame, line transect and releve. Additionally we discuss the biases introduced by the different techniques.
