Fig. 4. Correlograms of average Moran’s I coefficients on four diameter classes of S. lumutensis
within an 8-ha (400 200 m) plot: large trees (BIG >25 cm), pole trees (POL 4–25 cm),
saplings (SAP 2.0–2.5 cm) and seedlings (SEE 1.0–1.1 cm). Distance classes were defined at
five intervals, each of 20 m, from 0–20 m (class 1) to 80–100 m (class 5). Dotted lines represent
95% envelopes of average I distribution after 1000 permutations of individual multi-genotypes
within each diameter class.
The phenological observations using binocular showed five flowering trees (B004, B005, B026,
B325 and B385) during the flowering event in August 2002. However, paternity assignment
showed that an addition of seven trees (B003, B011, B012, B023, B030, B349 and B397)
within the 8-ha plot also contributed pollen for the reproduction of the four mother trees. In
other words, these trees might have flowered but at low density which could not be picked up
through binoculars. The dbh of the flowering trees ranged from 31–110 cm and this allowed us
to make the assumption that trees above 30 cm dbh can be considered as reproductively mature.
