Title
Silvicultural characteristics and management of miombo woodlands
E.N. Chidumayo 1993
Other claims from this paper (14)
- Observation Most miombo woodland species are deciduous during the dry season but flush before it ends.
- Observation Flowering occurs throughout the year with a peak during August-November.
- Observation In many species fruit production is irregular.
- Observation In many species seed dormancy is rare.
- Observation Seed germination generally occurs during the rainy season immediately after dispersal.
- Observation Germination rates of miombo species are good.
- Mechanism Seedlings grow very slowly because they initially allocate more biomass to root growth.
- Association Shoot growth is hampered by recurrent dieback caused by drought and fire.
- Observation Post-felling regeneration of miombo is from coppice of stump and root origin and from stunted seedlings in the herb layer.
- Observation Recruitment from seedlings in the first regrowth makes up over 50% of tree density.
- Observation Most species require high light intensities for sapling development.
- Association Competition and fire reduce tree density during regrowth maturation.
- Mechanism Many silvicultural characteristics of miombo woodland are adaptations to fire, drought and felling.
- Recommendation Future management of miombo woodland should take into account silvicultural characteristics of the constituent species.
