Figure 23.1 Size distributions of (a) a shade-intolerant pioneer (Goethalsia meiantha) and (b) a shade-tolerant
pioneer (Inga thibaudiana) in three secondary forests of different age since abandonment in northeastern Costa Rica.
Forest sites are abbreviated as follows: CR=Cuatro Rios, LEP=Lindero el Peje; LS=Lindero Sur; TIR=Tirimbina.
Site ages are in parentheses. Size classes are defined as follows: 20 cm ht>class 1<1 cm dbh≤class 2<2.5 cm
dbh≤class 3<5 cm dbh≤class 4<10 cm dbh≤class 5<25 cm dbh≤class 6.
