Calcareous grassland fidelity score |
A measure of how strongly species are associated with calcareous (chalk and limestone) grassland habitats.
|
quality index |
calcareous substrates |
Soils that are mostly or partly composed of calcium carbonate. They can be split into chalk and limestone. |
resource |
cambial layer |
The layer directly beneath bark that transfers food within the trees. |
resource |
cambial layer submerged |
Species associated with submerged trunks and branches, also classed as coarse woody debris in the wetland classification |
resource |
canopy |
Species that live within the leaf canopy of a tree or shrub. |
resource |
carrion |
Species that are associated only with carrion (as opposed to both dung and carrion). |

status |
chalk |
A fine white limestone rock. Soils are soft, often mixed with sand. |
resource |
clay |
A fine-grained soil that tends to retain water. |
resource |
coarse woody debris |
Coarse woody debris (CWD) is a term for fallen dead trees and large branches lodged in water courses and saturated with water. They can be fully or partially submerged and can be highly mobile, but can also form significant log jams. |

Coarse woody debris fidelity score |
A measure of how strongly species are associated with coarse woody debris. |
quality index |
coastal |
A biotope that includes all habitats affected by the tides next to the shorelines, namely beaches, rocky shores and saltmarsh. It also includes coastal habitats that are not wetlands, i.e. not directly affected by the tide (e.g. dunes, cliff tops). |

quality index |
compost/manure heaps |
Associated with compost or manure heaps, e.g. in gardens, stables and farms. Includes species feeding on decaying organic matter and their predators. |
