status |
|
exposed sea-cliff |
A feature of coastal situations where wind and salt blast on rocky coastal cliffs combine with shallow freely-draining soils to restrict establishment of plants along exposed cliff edges. |

exposed riverine sediments |
Exposed riverine sediments (ERS) are present in the shoals, bars and spits present in river channels which are periodically exposed during periods of normal or lower than average flow. The sediments range in size from cobbles and boulders to sand and fine silts. |

exposed clay |
Clay and clay covered by a thin layer of moss and / or lichen, but with the substrate being particularly obvious. |

exposed chalk |
Chalk and chalk covered by a thin layer of moss and / or lichen, but with the substrate being particularly obvious. |

epiphytes |
Plants and lichens that grow upon trees. |
resource |
|
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. |

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 |
|
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 |
|
dry wood mould |
Dry, fibrous wood mould. |
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 |
|
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 |
|
deep water |
Water within a lake of more than a few metres deep that is free of aquatic plant growth. |
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 |
|
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. |

dead trunks & branches |

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. |

Conservation status |
Any designated status, such as Red Data listing, or Species of Principal Importance under the NERC Act. |

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 |

Coarse woody debris fidelity score |
A measure of how strongly species are associated with coarse woody debris. |

|
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. |
