Tree Parameters:
- For trees below 25cm, just measure the height, the rest we default to 0 branches, 4cm for canopy 1, 4cm for canopy 2
- If a tree has more than 20 or more branches, just write 20 (maximum cap)
- A tree is natural if:
(i) It is outside the pattern of planted mangroves
(ii) It is a different height to the planted mangroves
(iii) It is not planted in pairs
