Measuring Tape Interrupted Belt Quadrat Species Outline Sample

This card outlines the steps for sampling an area using an interrupted belt transect method. It involves taking samples at regular intervals along a measuring tape.

Bu kart, ekolojik bir alanda örneklem yapmak için kesintili bir kuşak transek yöntemi kullanma adımlarını açıklamaktadır. Bu, bir ölçüm bandı boyunca düzenli aralıklarla örnekler almayı içerir.

Front Outline how to sample an area using interrupted belt transect.
Back Interrupted belt transect:
  1. Extend a measuring tape from one side of the habitat to another. 
  2. Place a quadrat at 0m on the tape.
  3. Count the numbers/estimate percentage cover of each species. 
  4. Use a key to identify each species.
  5. Record results in a table.
  6. Move the quadrat along the measuring tape.
  7. Repeat step 3-5 at regular intervals along the measuring tape.
  8. Continue until the full length of the measuring tape has been sampled.
  9. Calculate the average of each species.
  10. A bar chart can be drawn to show the data obtained.
