| FECs Group | Parameter | Attributes | Priority | Extreme Events | Scale | Complexity | Recurrance | Method | Notes |
|---|---|---|---|---|---|---|---|---|---|
| Herbivores (Terrestrial arthropods) | Diversity | Species richness (estimates) | Essential | Local | Basic | Annually first; 3-5 years afterwards | Opportunistic collection of adults and/or standardized sweep samples/ systematic surveys of plants for larvae | Some taxonomy required. | |
| Herbivores (Terrestrial arthropods) | Abundance | Relative number per sweep transect; visual surveys, number per beat-sheets (density) | Recommended | Local | Advanced | Annually | Opportunistic collection of adults; standardized sweep samples; standardized beat-sheet sample / systematic surveys of plants for larvae | Difficult to achieve by non-specialist | |
| Herbivores (Terrestrial arthropods) | Spatial structure | Species presence/absence | Essential |
|
| Annually first; 3-5 years afterwards | Opportunistic collection of adults; standardized sweep samples; standardized beat-sheet sample / systematic surveys of plants for larvae. Also using expert knowledge, e-databases (e.g., e-butterfly), community/ local knowledge | Feasible and important (e.g., range expansions) | |
| Herbivores (Terrestrial arthropods) | Phenology | Seasonal activity patterns | Recommended | Local | Basic | Annually | Timing of first appearance, local/ Indigenous Knowledge, season-long sampling | Requires season-long monitoring, which is time consuming and difficult, but potentially of high priority to monitor outbreaks | |
| Herbivores (Terrestrial arthropods) | Ecosystem functions and processes: herbivory | Plant damage | Essential | Local | Basic | Annually | % leaf area lost, index of leaf damage, leaf miner damage | This is an indirect measure of insect feeding, Time consuming; may be difficult to achieve. | |
| Herbivores (Terrestrial arthropods) | Health | Body size, pupal mass | Recommended | Local | Basic | Annually first; 3-5 years afterwards | Weight of caterpillars, pupal cases | ||
| Herbivores (Terrestrial arthropods) | Demographics and temporal cycles | Population estimates (cycles), larvae/adult dynamics | Recommended | Local | Basic | Annually | Opportunistic collection of adults; standardized sweep samples; standardized beat-sheet sample / systematic surveys of plants for larvae | May be high priority if damage is significant |
