Description

Clean water and air, lumber for wood products, habitats for species, stable soil, recreational activities, and environmental beauty are all provided by forests. They also contribute significantly to the economy by generating marketable timber. Forests also offer many additional plant items that may be harvested, including fruits, nuts, mushrooms, and latex for making rubber. Many animal species are also hunted in woods for entertainment or food. Other benefits and services provided by forests include the regulation of river flows and erosion, the removal of pollutants from the air and water, and other benefits and services critical to both human wellbeing and ecological integrity. All of these forest values are significant, albeit their significance is not often measured in monetary terms. Furthermore, many of these benefits are particularly well given by old-growth forests, which are typically incompatible with industrial forestry techniques. This is one of the factors making old-growth forest protection such a hot button issue in many parts of North America and beyond. In any event, it is obvious that when forests are destroyed or damaged, these crucial commodities and services they may offer are also gone [1].

The stress of timber harvesting and carbon emissions on natural forests is significantly reduced by planted forests. To balance the links between ecological advantages from biomass energy generation and environmental balance from lumber production, accurate measurement of the forest volumetric resources in forest plantations is essential. In this analysis, researchers analyzed the use of three multivariate regression approaches for predicting volumetric resources in subtropical forests using Spectrum Indices (SIs), Wavelet Features (WFs), and metrics from Light Detection and Ranging (LiDAR) obtained using Hyperspectral Imaging (HSI) data [2].

The stability of the biosphere and the carbon balance are maintained by natural forests, which among terrestrial ecosystems possess the most complex structure and richness. One important metric for assessing forests is Aboveground Biomass (AGB), which may estimate both the quantity and quality in natural forests. The effectiveness of forest management may be greatly increased by quick and accurate AGB calculations, which can also help us understand the forest cycle better. One of the newest spaceborne Light Detection and Ranging (LiDAR) sensors, the Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2), can penetrate forest canopies and provide precise, extensive data of forest vertical parameters [3].

ICESat-2's distinct footprints, however, are unable to deliver complete spatial AGB dispersion data. An improved Extreme Learning Machine (ELM) approach was put forth in this work to calculate the AGB of natural forests in China's eastern Qinghai- Xizang Plateau. To achieve continuous AGB mapping, ICESat-2 and synthetic Sentinel-2 photos from the Google Earth Engine (GEE) were combined. Support Vector Machine (SVM), KNearest Neighbour (kNN), and Back Poropagation (BP) models of neural networks were also built for comparison in order to confirm the efficacy of the improved strategy [4].

For the purpose of evaluating the model's accuracy, measured AGB values that were collected from the Forest Management Inventory (FMI) were employed. The findings indicate that the optimized ELM, which had an R2 value of 0.68 and a Root Mean Square Error (RMSE) score of 25.14 mg/ha, had the best estimating impact of all the models examined. The AGB forecast efficiency was significantly increased by the optimized ELM, which also yielded the lowest RMSE. These results demonstrate ICESat-2's capability to estimate the AGB of forest areas, opening up new opportunities for huge forest resource exploration in hostile environments at high altitudes [5].

Conclusion

Primary forest is indeed the outcome of a long-term natural dynamic in which people have no influence. In truth, archaeological evidence shows that people have existed for a very long time, even in the vast jungles of the Amazon and Congo Basins. The timber may be used by these forest residents, or they could practice shifting agriculture by thinning the forest. When these plots are removed, the dynamics of natural forestry are once again present. These brand-new woods, sometimes referred to as secondary forests, are composed of pioneer fast-growing species.

After several millennia, the flora's composition and structure begin to resemble the original forest once more. Humans plant trees in order to speed up the regrowth of the forest, boost production production, or create a forest habitat. These forest plantations often include a smaller variety of species, many of which have been bred to be more productive and manageable.
