This test is also very easy to standardise.
- Leaf Litter sorting involves collecting leaf litter then sifting through the material to find the invertebrates. Protective clothing should be worn, sample sizes should be the same and equal lengths of time should be spent sifting the leaf litter samples.
- Beat sampling is probably the most widely used technique for collecting invertebrates from vegetation. This is a good technique for collecting beetles, ants, bugs and spiders. Use a sturdy stick is used to beat the vegetation, stunning the invertebrates. They can be collected in a light colour shallow bag or off a drop sheet.
