Today we're going to be exploring various sampling strategies including the use of quadrats. It's usually not possible to look at every single individual of a species within a given area. It's also pretty rare that you'll be able to look at every single square metre within that area too. For that reason, field ecologists try and obtain something called a representative sample. This is when you look at a smaller area that represents patterns that are happening on a bigger scale.
