TL;DR: In this article, the authors considered that many Central European managed beech and oak forests should also be considered plantations if they developed from planted saplings, since the tree species composition of these stands resembles that of the natural forest vegetation.
Abstract: Largely artificial conifer plantations now cover much larger areas of Central Europe than the semi-natural broadleaved forests. In the North German Plain, the Harz and Ore Mountains and most other non-carbonate low mountains, the Upper Rhine Plain, the region of Nuremberg, the northern Prealps and the southwest Vienna Basin, forestry monocultures dominate the landscape. However, these stands are only homogenous in terms of their tree layer, and their undergrowth can be rich in shrubs or dwarf shrubs, herbs, mosses and fungi (see Fig. 8.1). In a strict sense, many Central European managed beech and oak forests should also be considered plantations if they developed from planted saplings. However, since the tree species composition of these stands resembles that of the natural forest vegetation, these managed forests are discussed in the chapters on natural forest vegetation (Chaps. 5, 6 and 7).

TL;DR: In this article, the relationship between the structure of phytocenoses representing different stages of the process of forest formation in the Polar Urals and moistening of ecotopes, as well as between the lower layers and forest tree stand are considered.
Abstract: Correlations between the structure of phytocenoses representing different stages of the process of forest formation in the Polar Urals and moistening of ecotopes, as well as between the lower layers and forest tree stand are considered. Current density of trees and undergrowth is not exhaustive of the ecotope capacity, and therefore open woodland can be transformed into closed forest. Perspectives of such a transformation within a certain plot may be assessed by percentage of mesophilic and relatively thermophilic (hypoarctic + boreal) species in the herb-dwarf shrub layer.

TL;DR: In this article, the authors used quadrat line transects to analyze the riparian vegetation of Suhuyon River, North Sulawesi, Indonesia, from upstream to downstream in February to July 2015.
Abstract: Riparian vegetation has important ecological roles in maintaining river quality. The declining of riparian vegetation will cause to decreasing of water quality and aquatic and terrestrial biodiversities. This study aimed to analyze riparian vegetation of Suhuyon River, North Sulawesi. Vegetation analysis method used in this study from upstream to downstream in February to July 2015. The method applied in vegetation analyzing was quadrat line transect. The plot size was 2 m x 2 m for undergrowth up to 1.5 m height. Riparian vegetation will be analyzed descriptevely with several indeces i.e. Shannon-Wiener diversity index (H’), Evenness Index, and Sorensen Similarity Index.Riparia zone has been used as agricultural land and settlements. Riparian plants are coconuts, bananas, manggoes, langsat, durio and arenga palm. Vegetation habitus are shurbs, epiphytes, lianas, and small trees. Riparian vegetation are classified into Acanthaceae, Amaranthaceae Araceae Aspleniaceae Asteraceae, Athyroaceae Caesalpiniaceae, Caryophyllaceae, Costaceae, Fabaceae, Magnoliaceae, Malvaceae, Marattiaceae, Melastomaceae, Mimosaceae Moraceae Myrtaceae Lamiaceae, Piperaceae, Poaceae, Rubiaceae, Selaginellaceae Thelypterdidacea, dan Verbenaceae. Riparian vegetasi were found 36 species and 24 families. Diversity index of undergrowth riparian vegetation of Suhuyon River are moderate fom upstream to downstream, i.e. 2.70; 2.73 and 2.25. Evenness values of third station showed the dominance of certain species. Evenness values are respectively from upstream to downstream i.e. 0.89; 0.91 and 0.83. Similarity index of riparian vegetation showed that undergrowth riparian vegetation is different i.e. 44% and 56% .

TL;DR: Since soil pH, N, P, K and organic carbon are the five main contributing factors for plant growth and diversity in the study area, natural resources managers must consider the budget and balance of these resources for protection and to ameliorate soil, vegetation degradation and nutrient limitation.
Abstract: An investigation on the forest and savanna vegetation types in NnamdiAzikiwe University, Awka campus, in Anambra state was carried out. This study was conducted on two communities (Science village forest vegetation type and Bank site savanna vegetation type) both located within the University Awka campus. The plot size of 5000 m-2 (50 m × 100 m) for the forest and 650 m-2 (25 m × 26 m) for savanna being their respective minimal areas were used. An analysis of the abundance of plant species above 1m in height in the forest vegetation type revealed that Elaeis Guineensis had the highest basal area (2268.59 M2ha-1) and the Gambeya Albida had the lowest basal area (0.72 M2ha-1). It also revealed that Elaeis Guineensis had the highest important value index (35.7778 %) and Gambeya Albida had the least significant important value index (0.7589 %). The results further revealed that there were 38 families identified in the community. An analysis of the abundance of plant species above 1 metre in height in the savanna vegetation type revealed that 15 families of plant species were identified in the community. It also revealed that Rothmannia Hispida(61.53M2ha-1), had the highest basal area while Napoleana Vogelii had the lowest basal area (1.03M2ha-1). It also showed that Terminalia Ivorensis (51.63%) had the highest important value index while Cnestis Ferruginia(1.03%) had the lowest important value index. A critical look at the abundance of undergrowth plant species in the forest vegetation type revealed that 12 families of plant species were identified in the community. It further showed that Setaria Longista had the higher significant relative density (31.38%) and Combretum Racemosum (0.42%), Cola hispid a(0.42%), Andropogangayanus(0.42%), Glyphaea Brevis(0.42%), and Holarrhaeno Flouribunda(0.42%) had the least relative density. The abundance of undergrowth plant species in the savanna vegetation type showed that 9 families of plant species were identified. The result also showed that the community had the plant species diversity value of 0.88. Since soil pH, N, P, K and organic carbon are the five main contributing factors for plant growth and diversity in the study area, natural resources managers must consider the budget and balance of these resources for protection and to ameliorate soil, vegetation degradation and nutrient limitation.

TL;DR: In this paper, a linear analysis of the factors affecting the undergrowth economic growth is proposed, and the basic principles involved in the linear analysis are analyzed, and a multiple linear regression model is established to analyze the influencing factors of under growth economic growth.
Abstract: In order to build a comprehensive and systematic management mechanism of forest management, make full use of limited forest land resources, and achieve the goal of sustainable development, this paper summarizes the influencing factors of current undergrowth economic development. Therefore, this paper proposes a linear analysis of the factors affecting the undergrowth economic growth. According to the current situation of economic development under forest, the model structure is designed in the view of linear analysis. In addition, the basic principles involved in the linear analysis are analyzed, and the multiple linear regression model is established to analyze the influencing factors of undergrowth economic growth. The results show that the method is effective and provides technical support for the rapid development of undergrowth economy.
