CONTENTS:
1. Why Capture Invertebrates?
- An Introduction to Invertebrates
- Different Orders - Structural Differences
- Use of Binomial Nomenclature versus English Names
- Conservation position - large numbers, greater chance of local,
notable or RDB species
- Position in food-chains for vertebrates
- Manage for botanical and inverts assures food chains for higher
species
- If you don't know what is there how can you manage for it?
- More complete species lists enable better decisions and provide
improved base-line for
monitoring changes in management regimes
- Greater profile for sites
- More chance of obtaining LNR, and/or SSSI status and fighting
off development claims
2. Where are Invertebrates To Be Found?
