Abstract Modern silviculture is based on simulating natural disturbance regimes on the one side and reducing their impact on the other side. Disturbances modify light regimes of forests along complex spatial patterns, and species participating in the ecosystem tend to have unique adaptations to the multitude of light conditions found in forests. We studied the height growth reaction of saplings from eight native North American tree species to different light availabilities in a Sierra Nevada mixed conifer forest. Large height growth differences occurred between species. Height growth increased for most species with increasing light availability. However, black oak but also incense cedar and tanoak reached an optimal value or saturation point of light availability at intermediate light levels, above which their growth stayed the same or slightly declined on average. A variety of stand conditions, representing the range from early to late successional stages, are beneficial to maintain tree species diversity across stands. Such a gradient of conditions can be achieved by diversifying silvicultural regimes and using regeneration approaches that mimic a range of disturbance intensities. The results add to knowledge on the species’ ecology by specifying their height growth in dependence of a quantified light environment. The quantification of the light environment can directly be linked to % canopy cover and a range of regeneration methods, respectively. With this, the results may help achieve a more precise and target-oriented management of Sierra Nevada mixed conifer forests.

Abstract: To give some scientific references for the multi-level configuration of plant community in urban green land, especially for how to choose undergrowth plants which have different light habits, this research investigated the canopy structure and determined understory light environment of 23 canopy tree species which are mostly applied in urban green land in Guangdong province using hemispherical photography. The results showed that understory light environment was influenced by canopy structure significantly and there were significant positive correlation (P < 0.001) between CO and TransDir, TransDif and TransTol, with the correlation coefficient (r) of 0.88, 0.95 and 0.91, respectively; and a extremely significant negative correlation between CO and LAI (r = -0.63; P < 0.001). Hemispherical photography has lots of advantages which are convenient, rapid, practical and accurate. It could not only monitor canopy structure but also determine single tree and canopy tree species which the canopy was broken. This method is supposed to contribute to quantitative research on understory light environment and is essential for scientific research and popularizing in the development of urban garden.
