The objective of this study was to determine the maximum depth, structure, diameter and
biomass of the roots of common woody species in two savanna physiognomies (savanna
woodland and open woody savanna) in Brazil?s Pantanal wetland. The root systems of 37
trees and 34 shrubs of 15 savanna species were excavated to measure their length and
depth and estimate the total root biomass through allometric relationships with stem
diameter at ground level. In general, statistical regression models between root weight and
stem diameter at ground level showed a significance of P < 0.05 and R2 values close to or
above 0.8. The average depths of the root system in wetland savanna woodland and open
woody savanna are 0.8 ± 0.3 m and 0.7 ± 0.2 m, respectively, and differ from the root
systems of savanna woody species in non-flooding areas, whose depth usually ranges from
3 to 19 m.Weattribute this difference to the adaptation of woody plant to the shallow water
table, particularly during the wet season. This singularity of woody species in wetland
savannas is important when considering biomass and carbon stocks for national and global
carbon inventories. |
