Hi! I'm calculate the tree crown cover in plots of 15 m of diameter (176.7 m2) and the percentage (CC%) of each one through the equation CC%= CC*100/176.7), but when I sum CC5 of the trees by plot some of them have more than 100%, did any could tell me how can work this?
This is to discriminate vegetation cover of each stand, I'm working on estimate fire severity by remote sensing.
Hope you can help me
Your assumption is; the total crown cover lays within the plot area. But it is not. Especially, you are working with Tropical or subtropical trees or aged trees the crown cover is wide. As well as dense vegetation is also giving a similar result. If there are several trees within the plot, the crown is over the plot area. Such an incident is pointing out the density of vegetation. You might use the % values as it is; because it is the indicator to identify the spread of crown area.
