Mangrove field data, Daintree National Park, Queensland

Field measurements were made on the 5th September 2000 along a 90 m long transect for a section of mangroves located between the beach and main road just north of Cape Tribulation (Queensland).
The transect was 90 m long and 10 m wide. The start and end points for the transect were measured using a hand-held GPS. Since tree cover reduced the GPS signal at the start and end points, GPS measurements were taken near the start and end points of the transect using the GPS (where the canopy was more open), then a distance and bearing made to the end points. For trees within the transect area having a circumference at breast height (CBH) greater than 15 cm, their location, CBH and an estimate of height were measured. Only the location was recorded for trees having a CBH below 15 cm (equivalent to a diameter at breast height (DBH) < 5cm). Tree height was measured ad libitum with a hand-held laser system. Mangrove species was also recorded when known.
