| FECs Group | Parameter | Attributes | Priority | Extreme Events | Scale | Complexity | Recurrance | Method | Notes |
|---|---|---|---|---|---|---|---|---|---|
| Prey for vertebrates | Diversity | Species richness (estimates) | Recommended | Local | Basic | Annually first; 3-5 years afterwards | Some taxonomy required. Spiders as top predators and as easily sampled taxa should be a priority | ||
| Prey for vertebrates | Abundance and productivity | Relative number per trap | Essential | Local |
| Annually if possible where bird studies are conducted; 3-5 years as minimum | Possible if standard protocols can be used. This is a key driver for insectivorous birds. | ||
| Prey for vertebrates | Spatial structure | Species presence/absence | Recommended |

| Annually first; 3-5 years afterwards | Possible if standard protocols can be used. This is a key driver for insectivorous birds. | ||
| Prey for vertebrates | Phenology | Seasonal activity patterns | Essential | Local | Basic | Annually if possible where bird studies are conducted; 3-5 years as minimum | Some taxonomy required. | ||
| Prey for vertebrates | Health and productivity (spiders only) | Body condition index, body size index, clutch size (wolf spiders) | Recommended | Local |
| Annually first; 3-5 years afterwards | Simple to conduct for some taxa, e.g., wolf spiders |
