Special Issue Information

Dear Colleagues,

According to the Global Forest Resources Assessment (FRA) 2020, forest degradation has become a global environmental issue due to human activities, severe climatic events, fire, pests, diseases and other environmental disturbances. Forest degradation is defined as the long-term reduction in the levels of goods and services including carbon loss, greenhouse gas emissions, wood production, biodiversity conservation, ecosystem functions, human health and, even worse, the decline of forest resilience—the ability of a forest ecosystem to re-organize and recover following disturbance. Forest degradation is one of the more challenging types of disturbances to measure and monitor. With the development of observation technology, the processes of forest degradation and restoration can be monitored. However, how to assess these degraded forests in a timely and accurate manner is still a considerable question. Nonetheless, it is society's obligation both to protect forests from any degradation, restoring and transforming them to be healthier, with better structure and function. Tackling forest degradation can be achieved through the implementation of silvicultural measures to restore and transform degraded forests to high-level forests (e.g. mitigation of degradation process, forest stand tending, natural regeneration, reforestation, afforestation), control of forest fires, conservation of marginal farmland to forest lands, development of protective shelterbelts in the environmental fragile sites, implementation of policies and measures for biodiversity and natural reserves conservation. This Special Issue aims to provide observation technology, driving forces and restoration methods to address degraded forests in terms of improving forest sustainability.

Potential topics include, but are not limited to:

  • Observation technology of degraded forests;
  • Structural and functional degradation of forests;
  • Degradation mechanisms of natural forests or plantation forests;
  • Plant-soil feedback of degraded forests;
  • Driving forces of degradation forests at larger scale;
  • Restoration or transformation methods of degraded forests;
  • Environmental effects of forest degradation or restoration;
  • New technologies and methods for forest ecological restoration;
  • Climate adapted reforestation for ecological restoration of degraded forests.

This study proposes a novel approach to estimate canopy density in Picea Schrenkiana var. Tianschanica forest sub-compartments by integrating optical and radar satellite data. This effort is aimed at enhancing methodologies for forest resource surveys and monitoring, particularly vital for the sustainable development of semi-arid mountainous areas with fragile ecological environments. The study area is the West Tianshan Mountain Nature Reserve in Xinjiang, which is characterized by its unique dominant tree species, Picea Schrenkiana. A total of 411 characteristic factors were extracted from Gaofen-2 (GF-2) sub-meter optical satellite imagery, Gaofen-3 (GF-3) multi-polarization synthetic aperture radar satellite imagery, and digital elevation model (DEM) data. Consequently, 17 characteristic parameters were selected based on their correlation with canopy density data to construct an estimation model. Three distinct models were developed, including a multiple stepwise regression model (a linear approach), a Back Propagation (BP) neural network model (a neural network-based method), and a Cubist model (a decision tree-based technique). The results indicate that combining optical and radar image characteristics significantly enhances accuracy, with an Average Absolute Percentage Precision (AAPP) value improvement in estimation accuracy from 76.50% (with optical image) and 78.50% (with radar image) to 78.66% (with both). Of the three models, the BP neural network model achieved the highest overall accuracy (79.19%). At the sub-component scale, the BP neural network model demonstrated superior accuracy in low canopy density estimation (75.37%), whereas the Cubist model, leveraging radar image characteristics, excelled in medium density estimations (87.46%). Notably, the integrated Cubist model combining optical and radar data achieved the highest accuracy for high canopy density estimation (89.17%). This study highlights the effectiveness of integrating optical and radar data for precise canopy density assessment, contributing significantly to ecological resource monitoring methodologies and environmental assessments.
