Dataset Attributes
| Attribute | Description |
|---|---|
| Abundance | Measure of abundance of the organism recorded |
| County | The name of the county within which the record was made |
| Lake code | Unique Water Framework Directive code to identify each lake |
| Position | Record position on the 100m transect used as part of the lake survey. The 100m transect is usually perpendicular to the shore. Position 0 is the shore, Position 1 = 2.5m from shore, Position 2 = 5m from shore, Position 3 = 7.5m from shore, Position 4 = 10m from shore, Position 5 = 25m from shore, Po |
| Position Depth | Water depth at which a sample was taken. As the majority of macrophytes found are rooted to the substrate it is the depth of water under which the macrophytes are growing. |
| Position distance(m) | This is the distance in meters from the lake shore (usually along the transect) |
