Special Issue Information

Dear Colleagues,

Forests play a crucial role in maintaining global ecological balance, biodiversity, and carbon sequestration. However, under the context of climate change and intense human activities, sustainable forest resource management faces unprecedented challenges. Traditional forest monitoring methods are often time-consuming and labor-intensive. In recent years, the rapid advancement of remote sensing technologies (such as LiDAR, multispectral/hyperspectral imaging, and radar) from various platforms (satellite, UAV, and terrestrial) has provided unprecedented opportunities for monitoring forest ecosystems with high precision and spatiotemporal resolution.

This Special Issue, "Remote Sensing-Driven Insights into Forest Growth and Sustainable Resource Management," aims to gather the latest research applying advanced remote sensing techniques to forest sciences. We welcome original research articles and reviews that explore innovative methodologies for estimating forest parameters, monitoring forest health and growth dynamics, and supporting sustainable management practices.

Potential topics include, but are not limited to:

  • Forest biomass and carbon stock estimation;
  • Monitoring of forest health, disturbances, and resilience;
  • UAV and LiDAR applications in forest inventory;
  • Integration of multi-source remote sensing data for silviculture;
  • Remote sensing-informed sustainable forest management and policy-making.

Populus pruinosa Schrenk is a keystone species in arid riparian ecosystems, where its physiological status is critical for biodiversity and soil stabilization. In this study, spectral reflectance, leaf chlorophyll density (CHD), and leaf water content (LWC) were measured for Populus pruinosa in the Tarim River headwater region and Awati County, Xinjiang, from July to October 2023. The aim was to estimate CHD using hyperspectral data combined with machine learning and to evaluate the effect of LWC on model accuracy. Raw spectra were preprocessed using Savitzky–Golay (SG) smoothing and continuous wavelet transform (CWT). A two-step feature selection strategy comprising Random Frog and iterative retaining informative variables (IRIV) was applied to extract characteristic bands. Three machine learning models—support vector machine (SVM), random forest (RF), and extreme gradient boosting (XGBoost)—were developed for CHD estimation with and without LWC as an additional input. Incorporating LWC consistently improved the predictive performance of all models. Without LWC, the RF model achieved the best accuracy (training R2 = 0.842, test R2 = 0.830), whereas after LWC integration, XGBoost reached the optimal performance (training R2 = 0.871, test R2 = 0.865). SHAP analysis identified the 687 nm wavelength and its interaction with LWC as the most important predictors. These results indicate that combining spectral information with LWC effectively improves the accuracy and stability of CHD estimation for Populus pruinosa, providing a reliable non-destructive approach for assessing forest ecosystem physiological status—a key contribution to the sustainable management of arid riparian forests.

Accurate prediction of forest fires is crucial for enhancing regional fire prevention and control. Existing models frequently rely on static factors such as weather and terrain, while insufficiently taking into account the Fuel Moisture Content (FMC), a critical internal factor that directly determines fire behavior. Instead, proxies like the Normalized Difference Vegetation Index (NDVI) are commonly employed, which weakens the physical foundation of predictions. This study assesses the marginal contribution of integrating dynamic FMC into fire prediction models. Concentrating on California, we developed a random-forest-based model that incorporates high-resolution FMC products retrieved by our team, along with meteorological, topographic, vegetation, and anthropogenic data. Through comparative experiments and SHapley Additive exPlanations (SHAP) analysis, we evaluated model improvements and the contribution mechanisms of key drivers. The results indicated that: (1) Incorporating FMC significantly enhanced model performance, with precision and specificity increasing by 3.93% and 3.60%, respectively, and the Area Under the Curve (AUC) showing improvements, suggesting heightened sensitivity in detecting actual fire occurrences. (2) SHAP analysis disclosed nonlinear effects and threshold dynamics: temperature was the dominant positive driver (the fire risk soared above 20 °C); FMC demonstrated a negative correlation with fire risk, with 100% serving as a potential threshold; elevation presented an inverted U-shaped pattern (the peak risk occurred at 1000–1500 m); and population density exhibited a shifting influence from positive to negative. (3) The monthly risk maps for California in 2023 captured the seasonal progression of fire risk and spatial patterns consistent with historical fire points. The fire risk map for 9 September 2020 also demonstrated consistency with the spatial distribution of the actual fire points on that day. This study validates that the integration of dynamic FMC strengthens the mechanistic foundation and early-warning capacity of fire prediction models, providing scientific backing for targeted fire management.
