Structural characteristics of mangrove forests: compilation of LAI and other variables for experimental and survey sites

Brief description

These data describe structural characteristics of mangrove forests at known locations. Some of the data is from sites where trees have been fertilized with nitrogen or phosphorus, while other data are from point centre quarter transects which were used to characterize the site.

Lineage

Maintenance and Update Frequency: notPlanned

Statement: Variable - Method\
\
Position (Lat/Long) - Estimated with hand held GPS (Garmin)\
Location - Name of the location of the site (closed town, landmark or coastal feature)\
Vegetation - Categorized as either mangrove, tidal marsh, cyanobacterial mat or no-veg\
Species - Ususally dominant species, but noted where there is a mix of species\
Mean tree height - Measured with telescoping tree pole. Mean of 4 individuals closest to the point.\
\
Salinity - Extracted from 30 cm depth using a suction device (McKee 1993) and measured with a hand held refractometer.\
\
Leaf area index (LAI) - Measured with hemispherical photography (Nikon) and processed with software Hemiview (Delta T, UK).\
\
Basal area - Estimated as the mean of basal area of four individuals muliplied by stem density. Basal area is derived from measurements of circumference (mean dbh). \
\
Stem density - Estimated by the Point Centre Quarter method. Density is the inverse of the mean distance of 4 nearest trees to the GPS point.\
\
\
Sites have been maintained since as early as 2000 from funding from a range of sources including the Smithsonian Institution and the Australian Research Council. Please contact Catherine Lovelock for details. GPS locations for many sites were provided by Ray Feller. \
