The relative importance of different regeneration mechanisms in a selectively cut savanna-woodland in Burkina Faso, West Africa

Coppicing ability of dry miombo woodland species harvested for traditional charcoal production in Zambia: a win–win strategy for sustaining rural livelihoods and recovering a woodland ecosystem

“…Resprouting is a key attribute of resilience and productivity of the woodland savannas (Shackleton 2001). The ability of most of the tropical dry forest species to coppice has been observed in studies of (Shackleton 2000;Kaschula et al 2005) and the miombo ecoregion (Luoga et al 2004;Syampungani and Chirwa 2011;Chirwa et al 2014) and Sudanian savannawoodlands of West Africa (Ky-Dembele et al 2007;Dayamba et al 2011) because most tropical dry forest species generally have extensive vertical and horizontal root systems that facilitate recuperation after cutting (Mistry 2000). However, the observed inter-specific difference in the number of coppice stumps in the present study could be related to their initial stocking density in the stand and the preference of the local people.…”

“…Regulatory policies are not based on strong evidence about the recovery potential of the woodlands although silvicultural systems based on disturbance-recovery knowledge (Geldenhuys 2010) could be developed to maintain trade-offs between woodland recovery and sustainable forest-based livelihoods. For example, coppice management for fuel wood and charcoal could be a possible option because most tropical dry forest and woodland species have the ability to coppice vigorously following cutting (Luoga et al 2004;Kaschula et al 2005;Ky-Dembele et al 2007;Mostacedo et al 2009;Dayamba et al 2011;Lèvesque et al 2011). Furthermore, the coppices, with an already well-established root system, grow rapidly compared with newly established seedlings (Grundy 1995), greatly contributing to the rapid recovery of disturbed woodland ecosystems.…”

Relative importance of various regeneration mechanisms in different restoration stages of Quercus variabilis forest after selective logging

“…The relative importance of these two regeneration mechanisms during forest recovery was determined by species composition and biology of disturbed forest, and the origin and intensity of disturbance (Kennard et al, 2002;Ky-Dembele et al, 2007). The regeneration of some forests after disturbance, such as burning, is dominated by asexual recruits (e.g., sprouts) rather than shoots established from seeds Yaoqin- Xue et al / Forest Systems (2014) 23(2): 199-208 (Hoffmann, 1998;Kennard et al, 2002).…”

In other forests, such as the Nazinon forest, sexual reproduction is the predominant mechanism after selective cutting (Ky-Dembele et al, 2007). Less intense disturbances, such as canopy opening, may stimulate more seeds to germinate (Vázquez-Yanes and Orozco-Segovia, 1993).…”

“…Asexual reproduction in Chinese cork oak primarily involves sprouts arising from the stem base, stump, and root, similar to Quercus nigra L., Quercus pagoda Raf., Detarium microcarpum Guill. & Perr., Acacia dudgeoni Craib ex Holland, Fagus grandifolia Ehrh., and Quercus liaotungensis Koidz (Gardiner and Helmig, 1997;Lockhart and Chambers, 2007;Ky-Dembele et al, 2007;Beaudet and Messier et al, 2008;Rong et al, 2013). To develop a management plan for Chinese cork oak forest recovery, understanding which reproduction is predominant in different forest recovery stages is necessary.…”
