A Shelterwood Method for Regenerating Red Oak in the Southern Appalachians

1990-12-01

David L. Loftis

Abstract A shelterwood method is described that provides stand conditions that enhance the growth of established red oak advance reproduction, thereby improving the chances of maintaining an oak component in … Abstract A shelterwood method is described that provides stand conditions that enhance the growth of established red oak advance reproduction, thereby improving the chances of maintaining an oak component in the next stand. Stocking of a mature, fully stocked stand is reduced to 60%, 65%, and 70% of initial stand basal area where oak site index is 70, 80, and 90 ft, respectively. The basal area reduction is accomplished from below using herbicides, leaving the main canopy essentially intact. This level and method of treatment prevents yellow-poplar, a primary competitor of red oak, from becoming established and growing prior to the final removal cut, and it eliminates most sprout competition from shade-tolerant subcanopy species after the final removal cut. The final removal cut can be made approximately 10 years after the initial treatment. For. Sci. 36(4):917-929.

Carl D. Monk

Percentage of evergreenness in 158 forest stands from seven community types in north—central Florida ranged from 0 to 100. In general, the evergreen species are more important on dry sterile … Percentage of evergreenness in 158 forest stands from seven community types in north—central Florida ranged from 0 to 100. In general, the evergreen species are more important on dry sterile sites and the deciduous species on mesic fertile sites. Nine environmental variables or combinations of variables accounted for approximately 51% of the variation in stand evergreenness. The segregation of evergreen species to dry sterile sites may be related to the gradual return of nutrients to the soil or the establishment of a more closed mineral cycle through (1) the leaching of nutrients from leaves and (2) year—round leaf fall.

A simple and commonly used … In the context of a random effects model for meta-analysis, a number of methods are available to estimate confidence limits for the overall mean effect. A simple and commonly used method is the DerSimonian and Laird approach. This paper discusses an alternative simple approach for constructing the confidence interval, based on the t-distribution. This approach has improved coverage probability compared to the DerSimonian and Laird method. Moreover, it is easy to calculate, and unlike some methods suggested in the statistical literature, no iterative computation is required.

Both withinand between-species comparisons of seed-size effects were made as … (1) Effects of seed size and seedling morphology on the establishment of six monocarpic perennials were examined in glasshouse experiments. Both withinand between-species comparisons of seed-size effects were made as seed weight varied by more than two orders of magnitude among species and by 3 to 20-fold within a species. Experiments were conducted in four ground-cover types: bare soil, litter cover, vegetated, and vegetated plus litter. (2) In vegetated cover, emergence of the two small-seeded species, Verbascum thapsus and Oenothera biennis, was significantly lower than in litter and bare soil. In contrast, emergence of the medium (Dacus carota and Dipsacus sylvestris) and large-seeded species (Tragopogon dubius and Arctium minus), was not significantly reduced in the presence of vegetation. Although the rate of emergence of all six species was significantly reduced in vegetated cover, there were no between species differences in seedling emergence rates in any cover type. (3) Relative growth rates of all six species were significantly lower in vegetated cover compared with litter and bare soil and the effect was greatest on the small-seeded species. At the end of the experiment, seedling weight in vegetated cover was positively correlated with seed weight. In non-competitive cover types (litter and bare soil), seedling weight was independent of initial seed weight. (4) Relative growth rates of seedlings in non-competitive cover types were inversely related to seed size. In bare soil and litter, the small-seeded species had relative growth rates twice those of the large-seeded species. In vegetated cover this pattern was reversed; the species with large seeds had the highest relative growth rates. (5) The growth form of a seedling did not have any effect on its probability of establishment in any cover type. Species with different growth forms and similar seed sizes had equal emergence, survival, and relative growth rates in all four cover types. (6) Within species differences in seed size had a significant effect on seedling growth in non-competitive cover, but had no effect on seedling growth in competitive cover. Thus, both withinand between-species differences in seed size had similar effects on seedling establishment success in different types of ground cover.

(i) The small watershed is a natural unit of suitable size for intensive study of nutrient cycling at the ecosystem level. (ii) It provides a means of reducing to a minimum, or virtually eliminating, the effect of the difficult-to-measure variables of geologic input and nutrient losses in deep seepage. Control of these variables makes possible accurate measurement of nutrient input and output (erosion) and therefore establishes the relationship of the smaller ecosystem to the larger biospheric cycles. (iii) The small-watershed approach provides a method whereby such important parameters as nutrient release from minerals (weathering) and annual nutrient budgets may be calculated. (iv) It provides a means of studying the interrelationships between the biota and the hydrologic cycle, various nutrient cycles, and energy flow in a single system. (v) Finally, with the small-watershed system we can test the effect of various land-management practices or environmental pollutants on nutrient cycling in natural systems.

Historical collections from North Korea deposited at foreign herbaria play … Background The digitization of historical collections aims to increase global access to scientific artifacts, especially those from currently inaccessible areas. Historical collections from North Korea deposited at foreign herbaria play a fundamental role in biodiversity transformation patterns. However, the biodiversity pattern distribution in this region remains poorly understood given the severe gaps in available geographic species distribution records. Access to a dominant proportion of primary biodiversity data remains difficult for the broader scientific and environmental community. The digitization of foreign collectors’ botanical collections of around 60,000 specimens from the Korean Peninsula before World War II is ongoing. In this paper, we aim to fill this gap by developing the first comprehensive, open-access database of biodiversity records for the Korean Peninsula. This paper provides a quantitative and general description of the specimens that Urbain Jean Faurie, Emile Joseph Taquet, and Ernest Henry Wilson kept in several herbaria. New information An open-access database of biodiversity records provides a simple guide to georeferencing historical collections. The first dataset described E. H. Wilson’s collection of woody plants in the Korean Peninsula preserved at the Harvard University Herbaria (A). This includes 1,087 records collected from 1917 to 1918. The other collections contained specimens by E. J. Taquet (4,727 specimens from Quelpaert, 1907–1914) and U. J. Faurie (3,659 specimens from North Korea and Quelpaert, 1901, 1906, and 1907). For each specimen, we recorded the species name, locality indication, collection date, collector, ecology, and revision label. This dataset contained more than 9,400 specimens, with 22 % of vascular plants from North Korea and 66% from Quelpaert (Jeju) island. In these collections, we included some images that correspond to the specimens in this dataset.

Background and Objectives: The fruiting phenology of tree species is closely linked to seasonal patterns and climatic factors, both of which play a crucial role in determining the availability of … Background and Objectives: The fruiting phenology of tree species is closely linked to seasonal patterns and climatic factors, both of which play a crucial role in determining the availability of food resources for a wide range of frugivores. These plant-animal interactions are fundamental to maintaining the stability of ecosystem and biodiversity. Amidst on going global climate change, understanding the mechanisms determining fruiting phenology is essential for predicting ecological dynamics and informing effective conservation planning. This is particularly crucial in the lower montane forest, which exhibits unique environmental conditions and is sensitive to climate change impacts, including rising temperatures and erratic rainfall. Nevertheless, understanding of climate change effects on fruiting phenology in Thailand’s montane forests remains insufficient. This research aimed to investigate the timing and magnitude of fruit production in tree species within a permanent lower montane forest plot at Huai Kog Ma, Doi Suthep-Pui National Park, Chiang Mai Province. It also examines the relationship between fruiting phenology and climatic factors, aiming to establish a comprehensive understanding of the environmental drivers shaping fruiting phenology in this lower montane forest ecosystem. Methodology: A comprehensive review of tree species in the lower montane forest permanent plot was conducted, drawing from databases and literature sources such as the Concise Encyclopedia of Plants in Thailand, the BGO Plant Database, the Useful Tropical Plants Database, and A Field Guide to Forest Trees of Northern Thailand, including a preliminary permanent plot survey to identify species bearing fleshy fruits consumed by wildlife. A diverse set of 32 species from 21 families was selected to ensure broad taxonomic representation. Fruiting phenology was monitored for at least five mature individuals per species using binoculars from October 2016 to December 2018. The average monthly fruiting percentage for each species was then calculated. The relationships between fruiting phenology and climatic factors were analyzed using multiple linear regression in R software. Main Results: Based on 32 tree species for fruit production monitoring, 18 species were found to bear fruits during the observation period. These species were categorized into three phenological groups. Group 1 comprised species fruiting in the dry season (November–April), including Eurya acuminata, Litsea cambodiana, and Prunus arborea. Group 2 consisted of species fruiting in the rainy season (May–October), including Baccaurea ramiflora, Protium serratum, Saurauia roxburghii, and Syzygium tetragonum. Group 3 comprised species that fruited continuously throughout the year without a specific season, including Acronychia pedunculata, Apodytes dimidiata, Canthiumera glabra, Choerospondias axillaris, Ficus curtipes, Ficus simplicissima, Ficus elmeri, Garcinia celebica, Madhuca floribunda, Melia azedarach, and Heptapleurum heptaphyllum. The timing and quantity of fruit production for each species were influenced by various factors, including tree size, soil nutrient availability, tree density in the area, and climatic conditions. Upon analyzing the relationship between fruiting phenology and climatic factors, it was observed that 8 out of 18 species exhibited a significant correlation with rainfall and temperature. These species can be classified into two distinct groups. The first group comprises four species whose fruiting patterns were significantly correlated with rainfall. Among these, two species—P. serratum and A. dimidiata—demonstrated a positive correlation with rainfall, while two species—F. simplicissima and M. floribunda—exhibited a negative correlation. The second group includes four species whose fruiting was significantly correlated with temperature. Among these, two species—B. ramiflora and F. curtipes—displayed a positive correlation with temperature, while the other two—A. pedunculata and E. acuminata— exhibited a negative correlation. In analyzing the study results in conjunction with climatic data spanning from 2019 to 2022, it was observed that monthly rainfall exhibited significant variability, particularly in the year 2022, during which precipitation experienced a notable increase during the rainy season. Conversely, temperature fluctuations were relatively minor. This observation suggests that the fruiting phenology of species associated with rainfall may also exhibit substantial variability. These findings suggest that species whose fruiting is sensitive to rainfall, particularly F. simplicissima and M. floribunda, may exhibit reduced fruit production under increased precipitation. As both are key food sources for various frugivores, alterations in their fruiting patterns could result in food scarcity, triggering intensified interspecific competition or dietary shifts among wildlife. Such behavioral changes may reduce seed dispersal opportunities for these species, potentially limiting their reproductive success and risking local extinction. If similar effects are experienced by other species. resulting disruption could compromise forest regeneration processes and destabilize the ecological balance of the lower montane forest system. Conclusion: On going climate change undeniably influences the alterations in the fruiting phenology of those species closely associated with climatic factors. Consequently, it affects frugivores that function as key seed dispersers and disrupts natural ecosystem regeneration processes. The study offers valuable insights into tree species, highly vulnerable to climate change, highlighting the urgent need for conservation strategies aimed at mitigating extinction risks. Such efforts are essential for sustaining ecological balance and promoting the long-term resilience of forest ecosystems under changing environmental conditions.

This … Endemic plant species, with their restricted distribution, are vulnerable to extinction due to human activities and environmental change. Monitoring their ecological characteristics and habitat relationships is crucial for conservation. This study examined plant communities to prioritize populations for conserving the Korean endemic species, Taihyun’s abelia (Zabelia tyaihyonii (Nakai) Hisauti & H.Hara), and to identify threats and strategies for its protection. Vegetation surveys were conducted, classifying communities and analyzing species composition differences. Habitat quality and zeta diversity, assessed using the InVEST model, identified three community types: Quercus dentata–Thuja orientalis (Com. 1), Fraxinus rhynchophylla–Buxus koreana (Com. 2), and Quercus dentata–Carex humilis var. nana (Com. 3). Community classification was supported by a multi-response permutation procedure (p < 0.001) and non-metric multidimensional scaling (R2 = 0.643). Species richness and soil calcium influenced species composition, and habitat quality was moderate (0.5562 ± 0.0294). Com. 1 and Com. 3 showed minimal zeta diversity decline, indicating strong habitat connectivity. However, fluctuations at zeta orders 8–12 suggested localized disturbances. Species turnover instability was linked to urbanization and disturbance. This study, using a diverse set of analytical tools, was able to pinpoint key features of habitat quality and composition associated with Z. tyaihyonii and the anthropogenic factors that will lead to its decline. Our work provides a road map for the conservation of other rare and endemic Korean plant species with similar conservation issues.

The precise extraction of ground elevation and vegetation canopy height is essential for advancing topographic and ecological research. The Terrestrial Ecosystem Carbon Inventory Satellite (referred to as TECIS hereafter) offers unprecedented capabilities for the large-scale, high-precision extraction of ground elevation and vegetation canopy height. Using the Northeast China Tiger and Leopard National Park as our study area, we first processed TECIS data to derive topographic and canopy height profiles. Subsequently, the accuracy of TECIS-derived ground and canopy height estimates was validated using onboard light detection and ranging (LiDAR) measurements. Finally, we systematically evaluated the influence of multiple factors on estimation accuracy. Our analysis revealed that TECIS-derived ground and canopy height estimates exhibited mean errors of 0.7 m and −0.35 m, respectively, with corresponding root mean square error (RMSE) values of 3.83 m and 2.70 m. Furthermore, slope gradient, vegetation coverage, and forest composition emerged as the dominant factors influencing canopy height estimation accuracy. These findings provide a scientific basis for optimizing the screening and application of TECIS data in global forest carbon monitoring.

Miq., an endangered species native to western Kyushu, Japan, forms locally isolated populations. In our previous studies, we conducted a distribution survey of 109 populations across four regions and performed phylogenetic analyses using chloroplast DNA to clarify their genetic structure and diversity. The primary objective of this study was to clearly compare and evaluate phenotypic differences that are considered to be genetically fixed among adaptive traits evolved in response to the native environments of each region. We evaluated morphological characteristics—such as floral parts, leaves, and plant form—under uniform cultivation conditions using seeds collected from native populations. As a result, region-specific phenotypes were identified, and diverse variations were observed both among and within regions. Furthermore, the presence of phenotypes with high coefficients of variation even within the same region suggests the existence of diverse gene pools suitable for various applications. This study not only contributes to understanding the regional adaptive strategies of C. incana, but also provides fundamental data for developing conservation plans for this endangered species. Additionally, the phenotypic information obtained is expected to be useful for breeding horticultural varieties and for setting future conservation priorities.

To … The wetland in the Yarlung Zangbo River Basin is an important part of the ecological barrier zone of the Qinghai–Tibet Plateau and exerts a significant influence on the climate. To elucidate the evolutionary characteristics and potential causes of wetlands in the Yarlung Zangbo River Basin against the background of “warming-humidification” of the plateau, this study focused on the spatial–temporal changes of wetlands in the Yarlung Zangbo River from 1990 to 2020 and simultaneously discussed the contribution of natural factors to these wetland changes. The data used in this study encompassed meteorological observation, the Digital Elevation Model (DEM), land use remote sensing monitoring, the vegetation index and other relevant data, and the methods used were mainly hydrological analysis, landscape change dynamic analysis and GeoDetector. The research findings indicated the following: (1) The wetland area in the Yarlung Zangbo River Basin exhibits significant fluctuations. The wetland area increased steadily from 1990 to 2005, followed by a slight decline after 2005, reflecting the changing process of “humidification–drought–humidification–drought”. Nevertheless, the overall trend over the 30 years has been an increase in wetland area (a total increase of 14.92%), primarily driven by the conversion of forest and grassland. (2) The wetlands in the Yarlung Zangbo River Basin are mainly distributed in the lower river basin, especially in the Niyang River basin and the Yigong–Parlung Zangbo basin. The spatial distribution of these wetlands remained relatively stable over the 30 years studied. (3) The driving factor analysis results showed that the three main natural factors leading to the increase and reduction in wetland area include vegetation cover change, precipitation and evapotranspiration. Vegetation cover change contributed the most to the increase in wetlands in the Yarlung Zangbo River basin, and evapotranspiration played a decisive role in the reduction in wetland area. This study provided valuable perspectives for wetlands, water resources and ecosystem assessments in the Yarlung Zangbo River Basin and the broader Qinghai–Tibet Plateau region.

Methods We conducted a retrospective analysis of 115 adult patients with oligodendroglioma at our institution from January 2010 to December 2020. Inclusion criteria encompassed histologically and molecularly confirmed grade 2 and 3 oligodendroglioma, age above 18 years, availability of pre-and post-operative imaging and complete follow-up data. Surgical outcomes were categorized by EOR and volumetric assessments were performed using neuroimaging. Mean OS and PFS were calculated using the Kaplan-Meier method (As mortality was &lt; 50%) and univariate/multivariate analyses were conducted to identify prognostic factors. Results The cohort had a median age of 42 years (range 18-77), with GTR achieved in 47% of primary operations. Median follow-up was 6.3 years. OS was significantly influenced by age (p &lt; 0.0001) and EOR, with a mean OS of 134 months and mean PFS of 117 months. Volumetric reduction of tumor volume greater than 80% correlated positively with both OS and PFS. The analysis also highlighted the importance of adjuvant therapy in improving PFS. Conclusion This study confirms that younger age, extensive volumetric reduction, and intraoperative adjuncts are associated with improved OS and PFS in patients with oligodendroglioma. While the EOR impacts OS significantly in grade 3 tumors, further research is necessary to determine optimal surgical strategies for grade 2 oligodendrogliomas.

A total of 515 vascular plant species were recorded, including rare species, alien species, and Korean endemic plants. To assess ecological patterns, the Naturalization Index (NI), Urbanization Index (UI), and Sørensen similarity index were applied. The results showed that Mt. Seoraksan, Mt. Deogyusan, and Mt. Taebaeksan had relatively high NI and UI values, while Mt. Jirisan showed a comparatively low UI value. Among disturbance types, the hiking trail (HT) type, located in a high-altitude area with limited accessibility, also recorded lower values. Floristic similarity with reference ecosystems was higher in Mt. Jirisan, Mt. Deogyusan, and Mt. Taebaeksan, whereas Mt. Seoraksan exhibited the lowest similarity. The overall similarity between disturbance types was low, and the composition of plant species varied across disturbance types. These results suggest that differences in disturbance intensity, driven by the disturbance type and topographic conditions, influences the floristic composition. The findings of this study can serve as baseline data for developing site-specific restoration strategies for disturbed sites in the future.

Its populations are limited to high-altitude habitats, with recent surveys confirming survival only in Gayasan. This study aimed to assess the population size and ecological traits of P. hallaisanensis to inform conservation strategies. We established 23 quadrats at 1400–1410 m above sea level and collected microhabitat data (air temperature, soil moisture, electroconductivity, vegetation cover, and species richness) from 2022 to 2024. Flora composition and pollinator species were surveyed, with bumblebees (Bombus ignitus, B. hypocrita sapporoensis) identified as the most frequent pollinators. General linear mixed models and Pearson’s correlation analysis showed a strong positive relationship between species richness and population size and between vegetation cover and stem height. The study area’s average temperature was 6.3 °C below Republic of Korea’s national average, suggesting that climate change could disrupt the microclimatic conditions necessary for this species’ survival. The findings highlight the importance of maintaining plant diversity and controlling invasive woody species to sustain P. hallaisanensis populations. Targeted conservation measures, including habitat management and ex situ propagation, are recommended to safeguard this vulnerable species.
