Understory light regimes have a major impact on seedling growth and patterns of forest regeneration. Many researchers have reported understory light regimes for relatively small areas, and then extrapolated their results to the landscape level with little knowledge of landscape-level heterogeneity. We used hemispherical photography to characterize understory light regimes at both the watershed and landscape scales within the Fushan Experimental Forest in northeastern Taiwan. We established 20 transects, 7 of which were located in Experimental Watershed #1 and the other 13 were scattered across an area of 150 ha at the Fushan Experimental Forest. Understory light was not normally distributed across the Fushan Experimental Forest, with some microsites having yew high light levels due to typhoon-induced canopy damage. Median understory light levels exceeded 15% of the incident sunlight at both the watershed and landscape scales. These light levels are much higher than those reported for many mature tropical and temperate forests in other parts of the world, where understory light levels of ＜5% of incident sunlight are common. Aspect, rather than spatial scale, had the largest impact on undercanopy light. In forests with rough topography, utilizing transects that run from the ridge to the valley is more likely to adequately characterize spatial heterogeneity than plots or a few longer transects.

In this paper, we attempt to establish bamboo charcoal quality evaluation indicators in Taiwan using the Delphi technique. After synthesizing expert opinions from 3 rounds of questionnaires, bamboo charcoal products were first divided into 8 major use categories: human diet, home healthcare, air purification, cosmetics and cleaning, crafts and ornaments, hi-tech material, agriculture (farming, forestry, fishing, and livestock), and fuel. Then under each use category, the essential evaluation indicators were selected from a total of 40 indicators and categorized into 4 evaluation criteria: material supply with 6 indicators, production technology with 8 indicators, product quality with 20 indicators, and marketing with 6 indicators. The results showed that human dietary use required the most at 29 important indicators, and while fuel use required the least at only 6 important indicators.

Scaevola hainanensis Hance is an endangered plant species in Taiwan. Distribution of this species in Taiwan is restricted to 6 connected ditches, which cover an area smaller than 1 ha at the estuary of Jiangjun Stream, Tainan County, southwestern Taiwan. We examined the genetic variation with inter-simple sequence repeat (ISSR) fingerprints. Fifty samples from 6 ditches were collected. In total, 27 primers were used, and 233 bands were obtained, of which only 6 bands (2.58%) were polymorphic, indicating low levels of genetic variation. The analysis of molecular variance (AMOVA) revealed that 93.85% of the variance component was attributable to the variation among individuals within ditches. Low levels of the genetic differentiation coefficient among ditches, G(subscript ST)=0.172 and Nm=2.4, indicated that the ditches barely hinder gene flow between Scaevola populations. UPGMA cluster analysis and principal coordinate analysis revealed no major groupings among ditches or among plants. If the present habitat is damaged, the species will inevitably be confronted with extirpation from Taiwan. Therefore, we suggest that ex situ conservation should be conducted in order to enlarge the population size.

The main purpose of the present study was to model the relationship between meteorological factors and fine dead fuel moisture in Taiwan red pine (Pinus taiwanensis) forests. The study was conducted in Shei Pa and Yushan National Parks of Taiwan. Fuel moisture data were collected hourly on the sampled day by direct measurement of Taiwan red pine lifter samples. The linear regression models were selected to construct fuel moisture content equations. The results showed that the best variables to predict fuel moisture at both sites were relative humidity and air temperature.

In this paper, an integrated model that combines bio-physical components related to fire hazards and human behavioral components related to fire risks is proposed. The model is shown to be as an improvement over the theoretical fire danger model. It predicts occurrence/potential based on ignition probability and fire use intentions of forest hikers. Testing of the model was conducted in SheiPa and Yushan National Parks located in central and southern Taiwan. The candidate variables provide acceptable results that support the structure of this conceptual model. Due to limited research time in this study, further tests of the conceptual model are needed to evaluate and improve the performance of the model.

Seeds of Prunus campanulata are known for their morphological and physiological dormancy which can be broken by a combination of warm and cold stratification. This treatment is usually applied after storage and before sowing. The goal of this study was to evaluate the effectiveness of dormancy-breaking treatment before storage of Prunus campanulata seeds. Two treatment procedures were proposed. The first one involved warm stratification of freshly collected seeds at 30/20℃ or 25/15℃ for 6 wk, followed by drying to 3 mo is ture contents (4.8-5.3%, 11.6-11.8% and 16.3-17.1%) and storage at -20℃ or 5℃ for 3-12 mo. Stored seeds were mixed with sphagnum and stratified at 5℃ for 8 wk before germination test. The second one involved warm stratification at 30/20℃ for 6 wk followed by cold stratification at 5℃ for 8 wk for dormancy breaking, and then drying to 2 seed moisture contents (5.2 and 16.3%) for storage at -20℃ or 5℃ for 3-12 mo. Stored seeds were tested directly for germination. Evaluation criteria used were the germination percentage and mean germination time (MGT). The result showed that seeds stored at -20℃ or 5℃ for 12 mo maintained 70% germination or above with the 2 treatment procedures. However, the first treatment procedure reduced MGT and enhanced the uniformity of germination. A possible cause for the reduced seed germination percent age during storage is discussed.

The gene encoding cinnamate 4-hydroxylase (C4H) from Populus tremuloides (quaking aspen) was transferred in a sense or antisense orientation into a superior clone of Eucalyptus camaldulensis via Agrobacterium tumefaciens. Transformed cells, calli, shoots, and plants were obtained, and transformation was verified by polymerase chain reaction (PCR). Transgenic shoots carrying the C4H gene proliferated and elongated at a much greater rate than both transgenic control shoots harboring the β-glucouronidase (GUS) gene and untransformed control shoots. Two independent lines of each of the transgenic plants carrying sense or antisense C4H were produced. Genomic DNA analyses confirmed that the aspen C4H gene was successfully transferred and integrated into the chromosomal genome of these E. camaldulensis transgenic plants. More than 100 rooted cuttings derived from these transgenic plants were generated and have been out-planted for further characterization.

Seeds of China-fir were obtained from 42 provenances in 13 provinces of China. Height and diameter were measured at the ages of 11, 16, and 18 years. Wood density samples were taken by increment core at breast height and were assessed by the water displacement method. Isozyme frequencies of PGI, SKDH, and 6PGD were observed from electrophoresis. Wood density ranged from a high of 0.310 in Jiangsu Province to a low of 0.273 in Guizhou Province in southwestern China. The China-fir in these 2 provinces differed from those of their neighboring Provinces. Correlation between density and isozyme frequency was not significant for SKDH and 6PGD; it was weak for PGI. Since there were no linear geographic or climatic trends detected, random variation due to local factors appears to be a suitable description for wood density in China-fir.

The present paper reviews several topics on fire danger research in the world. First, sources of fire danger that consist of research in fire hazard and fire risk are reviewed, Second, studies in the development of fire danger rating, including history of different countries, approaches of devising fire danger rating, and fire danger modeling are described. Third, fire danger rating systems that are currently used around the world are compared. Fourth, studies in evaluation of the fire danger rating systems are analyzed. From the literature, it is known that research in forest fire danger rating systems commenced in the 1930s in North America. It is a complex task that requires integrating knowledge from biological, climatic, physical, and behavioral fields. There are various approaches to developing fire danger rating, such as the statistical approach, biophysical approach, social survey and observation, and GIS. Through decades of efforts, laboratory experiments have led to the development of various fire danger rating models based on physical principles or other factors. Based on these theoretical models, various fire danger rating systems have been established to provide guide-lines for various fire management needs.
