台湾森林资源保护与经营研究

台湾森林资源十分丰富。但是,在日本统治时期的台湾森林资源受到了战争时期的滥垦滥伐,损失惨重。抗战胜利后,台湾的森林保护与经营经历了"以林养林"、"植伐平衡"、"伐生平衡""保林造林"、"造重于伐"、"保林造林"、"生态维护"的森林资源恢复过程。到了上个世纪70年代,随着台湾的经济起飞,森林的生态效益日益凸显,森林资源采伐逐渐减少。到了上世纪80年代,国有林采伐全部停止,台湾的森林资源保护与经营开始朝着生态保育、森林游憩、城市森林、社区林业等方向发展。

Evaluating the impacts of a carbon tax on imported forest products—evidence from Taiwan

Levying a carbon tax is one of the approaches used to reduce greenhouse gas emissions (GHGEs) and has been adopted in a number of countries since the Kyoto Protocol. Applying such an approach in the forest sector may have important policy implications. The main purpose of this paper is to investigate the effects of a carbon tax on imported forest products using Taiwan as an example. Taiwan relies on foreign imported timber and such consumption of harvested wood products (HWPs) lengthens the storage of carbon beyond the life of the tree. This study investigates the impacts of implementing a carbon tax on seven types of HWPs by applying the ARDL approach to imported timber demand functions in Taiwan. The empirical results show that the volumes of imported HWPs as well as carbon dioxide are significantly reduced once a carbon tax is implemented. These empirical outcomes provide some important forest policy implications for countries importing wood products.     

Ecophysiological characteristics of Taiwan alder (Alnus formosana) seedlings adapted to the subtropical region

We investigated several ecophysiological characteristics of seedlings of a low-elevation (100-200 m) and a high-elevation (2000-2400 m) population of Taiwan alder (Alnus formosana Makino) from subtropical Taiwan. Both populations had a wide optimal temperature range for photosynthesis, and there was little difference in the optimal temperature range for photosynthesis between populations. Photosynthetic rate (P(N)) was near maximal from 20 to 35 degrees C when seedlings of both the low-elevation and the high-elevation populations were acclimated at a day/night temperature of 30/23 degrees C. When seedlings were acclimated at a day/night temperature of 20/10 degrees C, P(N) was near maximal over the range 15-35 degrees C in the low-elevation population and 15-30 degrees C in the high-elevation population. Compared with nine other tree species native to Taiwan, Taiwan alder had a high P(N) and stomatal conductance (g(s)) under well-watered conditions. Reflecting its higher transpiration rate, Taiwan alder had a significantly greater leaf-air temperature difference than camphor (Cinnamomum camphora (L.) J. Presl), a co-occurring lowland tree species with leaves similar in shape and size to those of Taiwan alder. Despite higher g(s), high root and shoot hydraulic conductances enabled Taiwan alder to maintain higher leaf water potentials than camphor under well-watered conditions. We conclude that both photosynthetic characteristics and water relations are important factors enabling Taiwan alder to adapt to a wide temperature range, thereby ensuring its success at both high and low elevations in subtropical Taiwan.     

Breeding bird community composition in different successional vegetation in the montane coniferous forests zone of Taiwan

To examine the relationship between forest succession following fire and the composition of bird communities, we investigated the vegetation structure, bird population density, foraging behavior and guild structure in bamboo grasslands (11 years since the last fire), pine savanna (41 years), pine woodland (58 years), old-growth hemlock forest (never burned), and old-growth spruce forest (never burned) in the Tatachia area of central Taiwan. Canopy height, total foliage cover, tree density, total basal area of tree, total basal area of snags, foliage height diversity, and tree species richness all increased with successional age. However, shrub cover peaked in intermediate successional stages. The vertical profile of foliage cover was more diverse in later successional forests, which had more breeding bird species and ecological guilds. All the breeding bird species recorded in early and intermediate stages were also found distributed in the late successional forests. Because Taiwan has high precipitation and humidity, and most forest fires in Taiwan are caused by human activities, forest fires and large areas of early successional vegetation were probably rare in the mountain areas of Taiwan prior to the arrival of humans. Therefore, bird species have not had enough time to adapt to areas with early or intermediate successional vegetation. Moreover, late successional forests host all the major plant species found in the early and intermediate stages and have higher foliage height diversity index, which was positively correlated with the bird species richness and bird species diversity index in this study. As a result, all breeding bird species and guilds in the area can be found in late successional forests. Efforts for conserving avian diversity in Taiwan should focus on protecting the remaining native old-growth forests.
