Recording Plant Cover Values
If tagging an area, way or node there may be reasons to record the cover=* value of different species within an area. Presented below is a method for recording plant cover within a given area e.g. a wood or marsh.
- Percentage cover
cover:Robinia sp=*=51%,cover:Fagus sylvatica=*=8%
Percentage cover is usually recorded by using a quadrat or measuring out a specific area and then estimating by eye the coverage of different species within that area. Note: Remember that percentage cover can add up to over 100% because there are multiple layers/canopies within a habitat.
Possible text values
| Value | Percent of coverage | Comment |
|---|---|---|
| sparse | 1 to (10-20) | The distance between two perimeters of a Life Form is more than twice the average perimeter diameter. |
| open | (10-20) to (60-70) | Trees and Shrubs: the crowns are usually not interlocking |
| closed | more than (60-70) | Trees or Shrubs has crowns interlocking or touching. |
| The values relate to the Land Cover Classification System (LCCS) by FAO | ||
