“…Christian et al , 1994; Sage et al , 2006; Fletcher et al , 2010; Rowe et al , 2009), comparing diversity of SRWC to other types of forests is important for several reasons. First, SWRCs are sometimes planted on forested lands (e.g., Auclair and Bouvarel, 1992; Weih, 2004) and SRWC plantations may become a more prominent component of forested landscapes. Second, much of the agricultural land potentially used for SRWC may have been forested in the past, especially marginal cropland on which SRWC may be most profitable.…”

A meta-analysis of bird and mammal response to short-rotation woody crops

Short-rotation woody cropping (SRWC) refers to silvicultural systems designed to produce woody biomass using short harvest cycles (1-15 years), intensive silvicultural techniques, high-yielding varieties, and often coppice regeneration. Recent emphasis on alternatives to fossil fuels has spurred interest in producing SRWC on privately owned and intensively managed forests of North America. We examined potential bird and small mammal response at the stand level to conversion of existing, intensively managed forests to SRWCs using meta-analysis of existing studies. We found 257 effect sizes for birds (243 effect sizes) and mammals (14 effect sizes) from 8 studies involving Populus spp. plantations. Diversity and abundance of bird guilds were lower on short-rotation plantations compared with reference woodlands, while abundance of individual bird species was more variable and not consistently higher or lower on SRWC plantations. Shrub-associated birds were more abundant on SRWC plantations, but forest-associated and cavity-nesting birds were less abundant. Effects on birds appeared to decrease with age of the SRWC plantation, but plantation age was also confounded with variation in the type of reference forest used for comparison. Both guilds and species of mammals were less abundant on SRWC plantations. These conclusions are tentative because none of these studies directly compared SRWC plantations to intensively managed forests. Plantations of SRWCs could contribute to overall landscape diversity in forest-dominated landscapes by providing shrubby habitat structure for nonforest species. However, extensive conversion of mature or intensively managed forests to SRWC would likely decrease overall diversity, especially if they replace habitat types of high conservation value.

“…As shown in Table 8, previous studies on young poplar stumps have produced results consistent with those observed in this work. It has previously been shown that extensive coppice management (planting seedlings directly on the bare soil without herbicides or fertilizers) yielded lower stump survival rates than intensive management involving adding fertilizers and other beneficial chemicals [37]. In a study by Laureysens et al [29], the number of sprouts per living stump varied depending on the clone used, with Populus tricoharpa and P. trichocarpa × P. deltoides clones giving the greatest number of sprouts.…”

We investigated the sprouting capacity of poplar stumps in ten 8–21-year old stands growing on former farmland in Sweden situated between 55°N and 60°N. Seven of the stands were planted with the clone OP-42 (Populus maximowiczii Henry × Populus trichocarpa Torr. and Gray), one with black cottonwood (Populus trichocarpa Torr. and Gray) and two with unidentified clones. The poplars’ mean age was 17 years (range 8–21); six of the stands were growing on clay soils, two on tills and two on loam. The studied sprouts were 1–7 years old. Stump sprouting was observed in all studied stands. The number of sprouts per living stump decreased as sprout age increased. The mean dry mass of all sprouts stump−1 was 16.1 ± 14.0 (range 3.3–37.2) kg. A biomass equation was constructed for estimating sprout biomass from the sprouts’ diameter at 10 cm above the ground (D10). The mean total sprout weight per hectare for sprouts amounted to 16.9 ± 14.6 (range 1.2–41.3) tons ha−1 when calculated for the actual living stumps in the studied areas.

“…The main species under this cultivation regime in temperate climates are poplar (Populus spp) [12], willow (Salix spp) [13] and eucalyptus (Eucalyptus spp.) [14], and to a lesser extent, black locust (Robinia pseudoacacia L.) [15] and alder (Alnus spp.)…”
