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). resource
CE Critically endangered in Great Britain status

CE (Global) Critically endangered globally 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. resource
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). broad biotope
Coastal soft cliff fidelity score Coastal soft cliff fidelity score 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. label
conifer only Type of resource used by tree-associated species resource
conifer or broadleaved Type of resource used by tree-associated species - may be further divided into one of the two subcategories as appropriate subheading
Conservation status Any designated status, such as Red Data listing, or Species of Principal Importance under the NERC Act. general glossary
damp The soil water level is higher than in dry soils and will express around the soil surface for much of the time but never rises higher. Soil composition will greatly influence this, as will spring lines, position on slopes, aspect, and degrees of shading. resource
DD Data deficient in Great Britain status
DD (European) Data deficient in Europe status
DD (Global) Data deficient globally status
dead trunks & branches Species associated with dead trunks & branches within the bark and sapwood decay resource resource
decaying wood Wood-decay (saproxylic) species are associated with the decomposition of woody tissues and their agents, notably fungi, or are predators of other saproxylic species. habitat
decaying wood Decay specifically within a tree's heartwood, which may be subdivided into red-rot or white-rot fungi, having a strong impact on the species composition of the associated invertebrates. resource
deep litter Large accumulations of plant litter, such as sedge and grass litter, that are built up into mats and layers, often tens of centimetres deep. This tends to accumulate into dense mats, the lower sections being very damp. resource
deep water Water within a lake of more than a few metres deep that is free of aquatic plant growth. resource
drawdown zone: mud/shallow litter A resource for invertebrate species associated with exposed silt in areas of land inundated by water in the winter and early spring which dry in the summer. resource
dry The soil water level is well below the surface layer. The soil composition influences this as well, so the matrix may be particularly free-draining. resource
dry wood mould Dry, fibrous wood mould. resource
dung Species that are associated only with dung (as opposed to both dung and carrion). They may be directly feeding on the dung or be dung predators. resource
dung & carrion Vertebrate waste products and dead bodies within the landscape, ranging in size from small mammals/frogs/song birds up to large grazing animals. habitat

epiphyte fauna This assemblage type is found on the surface of trunks and branches of trees and shrubs. It includes grazers of epiphytes such as algae, lichens and mosses, as well as their predators and parasites. Some epiphyte feeders are also found on epiphytes growing on rocks and boulders. SAT
