Plant diversity is essential for human survival and economic well-being and also for the ecosystem function and stability. The total number of accessible seedlings and saplings in a forest community indicates the regeneration status/potential of a species or a forest. In this study, composition, diversity and population structure of three different forests (Banj oak, Chir-pine and Mixed oak-pine) was assessed around Nainital town of Uttarakhand state. Species richness and diversity were maximum in Banj-oak forest (9 species and 1.970, respectively) and minimum in Chir-pine forest (4 species an

In Ukraine, carbon stocks in forests are assessed by the gain-loss method since the national forest inventory is under development now. For the evaluation of main pools of oak and pine forest stands, typical for the Forest-steppe of Ukraine, the stock-difference method was used for the data of repeated observations on 18 intensive forest monitoring plots. The average carbon stock in the phytomass was 94.1 ± 19.8 tC·ha−1 and 93.4 ± 12.8 tC·ha−1, while in the deadwood, it was 8.8 ± 7.3 tC·ha−1 and 5.3 ± 4.3 tC·ha−1 for oak and pine forest stands, respectively.

Disturbance–succession models describe the relationship between the disturbance regime and the dominant tree species of a forest type. Such models are useful tools in ecosystem management and restoration, provided they are accurate. We tested a disturbance–succession model for the oak–pine ( Quercus spp. – Pinus spp.) forests of the Appalachian Mountains region using dendrochronological techniques. In this model, fire promotes pines, while fire suppression, bark beetle outbreaks, and ice storms encourage oaks. We analyzed nine Appalachian oak–pine stands for species establishment dates and the

The study of natural regeneration in pine stands, widespread in the Forest-Steppe of Ukraine, is crucial for transforming forest management towards sustainable, close-to-nature practices. This study aims to reveal the features of the natural regeneration of pine stands in the Left-bank Forest-Steppe of Ukraine, based on data from sample plots in Kharkiv and Sumy regions. Natural regeneration in pine-dominated stands is characterized by an age of 4–8 years and a low number of plants per hectare (1,000 [500–2,000]), with few plots containing enough regeneration (over 3,000 plants per hectare) to

Increasingly, conserved forests have become disturbed areas due to activities such as agriculture and livestock grazing. Landscape transformation leads to changes in biodiversity. Therefore, in this study, we compared the diversity of amphibians and reptiles in conserved areas (pine forest, oak-pine forest, and pine-oak forest) and disturbed areas in the Mixteca Oaxaqueña, southern Mexico. Fieldwork was conducted between July 2016 and June 2017, covering both the rainy and dry seasons. A total of eight amphibian species included in 5 families and 6 genera and 28 reptile species were recorded,

Forests play an important role in absorbing atmospheric carbon dioxide. Broadleaf Forests absorb more carbon as compared to the Pine Forests. Quantification of carbon in any vegetation and soil type is a basic step for evaluating the carbon sequestration potential of an ecosystem. To quantify the vegetation and soil carbon stocks in Oak and Pine Forests, above and below-ground biomass of both forests were estimated using stratified random sampling. Individual trees in the sample plots of both forest types were measured. Above-ground biomass of trees and saplings were estimated by using differe

The forests studied differ greatly in soil chemical characteristics, microbial biomass, and nutrient turnover rates.

ABSTRACT Palynological evidence from a sediment sequence in Owl Pond, Cape Cod, Massachusetts, documents the persistence of an area of oak-white pine dominated vegetation through most of the Holocene. The small size of the basin (1.6 ha) and its small catchment area suggest that it receives most pollen from nearby vegetation and consequently its pollen record can be used to study the history of the surrounding forests. The 10,500-year pollen record showed three main phases of relative vegetational stability. A late-glacial spruce-jack pine forest phase, followed by an early Holocene phase when

They are confined to the dry slopes with southern exposures, which are subject to more frequent forest fires than other ecotopes. This creates a real threat of complete extinction of the relict pine forests. The problem of preserving the formation is consistent with the need to study the spatial (parc
