“…Though controversial, it has been argued that climate change increases tree growth and hence forest productivity (Kirilenko and Sedjo, 2007;Reyer et al, 2017;Torzhkov et al, 2019;Ruiz-Pérez and Vico, 2020). However, even if there would be a possible increase, the impact of extreme weather interacting with increased pathogen and pest outbreaks will cause major losses and may even offset any gain in productivity (Reyer et al, 2017;Woods and Watts, 2019).…”

The Threat of the Combined Effect of Biotic and Abiotic Stress Factors in Forestry Under a Changing Climate

Plants encounter several biotic and abiotic stresses, usually in combination. This results in major economic losses in agriculture and forestry every year. Climate change aggravates the adverse effects of combined stresses and increases such losses. Trees suffer even more from the recurrence of biotic and abiotic stress combinations owing to their long lifecycle. Despite the effort to study the damage from individual stress factors, less attention has been given to the effect of the complex interactions between multiple biotic and abiotic stresses. In this review, we assess the importance, impact, and mitigation strategies of climate change driven interactions between biotic and abiotic stresses in forestry. The ecological and economic importance of biotic and abiotic stresses under different combinations is highlighted by their contribution to the decline of the global forest area through their direct and indirect roles in forest loss and to the decline of biodiversity resulting from local extinction of endangered species of trees, emission of biogenic volatile organic compounds, and reduction in the productivity and quality of forest products and services. The abiotic stress factors such as high temperature and drought increase forest disease and insect pest outbreaks, decrease the growth of trees, and cause tree mortality. Reports of massive tree mortality events caused by “hotter droughts” are increasing all over the world, affecting several genera of trees including some of the most important genera in plantation forests, such as Pine, Poplar, and Eucalyptus. While the biotic stress factors such as insect pests, pathogens, and parasitic plants have been reported to be associated with many of these mortality events, a considerable number of the reports have not taken into account the contribution of such biotic factors. The available mitigation strategies also tend to undermine the interactive effect under combined stresses. Thus, this discussion centers on mitigation strategies based on research and innovation, which build on models previously used to curb individual stresses.

“…Manipulasi tegakan yang paling umum dilakukan adalah mengatur kerapatan tegakan. Hal ini dilakukan dalam rangka mengurangi kepadatan tegakan untuk memperoleh potensi hasil tegakan yang lebih berkualitas (Woods & Watts, 2019) Degradasi hutan akan menggeser pola kurva struktur dan komposisi tegakan. Upaya pengelolaan hutan adalah minimal mengembalikan kurva struktur tegakan dan komposisi jenis mendekati kondisi awal atau sebelum penebangan.…”

The assessment of dipterocarp secondary forest recovery has important parameters namely stand density and diversity of forest species composition. This study aims to determine trends in patterns of change in density and diversity of secondary dipterocarp stands in natural forests based on variations in logging aged as projections of natural recovery that occurs in production natural forests. The study was conducted at the Natural Forest IUPHHK of PT. Gunung Gajah Abadi, Wahau, East Kalimantan. Data collection period on 2016-2019 by building temporary sampling plots of 11 plots (11 hectares) on 7 variations of logging aged. Density parameters (i.e. number of trees and basal area per unit area) and diversity (number of species, heterogeneity index, species abundance and evenness index) of Dipterocarp secondary forest stands will vary over the logging aged. The form of the relationship of stand density, abundance index and species evenness index is logarithmic regression form, while for base field parameter, the number and index of species diversity are polynomial or quadratic regression. Aged stands after logging is a factor that influences quite a large number of species composition, but is not large enough for other stand density and diversity parameters.
