Measurements of 20 QUDO & 20 PISA crown diameters (in 2 directions, not necessarily perpendicular) and DBHs were conducted. The purpose of data collection was to get a general idea of DBH~crown diameter allometry, but note that these trees were chosen in an ad-hoc manner and were not a random sample. DBH measured with a tape; crown width measured by two people with a tape, looking up to position the ends of the tape appropriately. GPS points from Ana's phone, IDOL alcatel, with the 'GPS coordinates' app.
