Identifying Insect-Induced Damage in Forests Through Remote Sensing
Neftaly’s High-Tech Solutions for Tracking Forest Health and Managing Insect Outbreaks

Introduction
Insect outbreaks—such as bark beetles, caterpillars, borers, and defoliators—pose a serious and growing threat to forests worldwide. These pests can cause widespread defoliation, tree mortality, and long-term degradation of ecosystem services.
Neftaly leverages advanced remote sensing technologies to detect and assess insect-induced damage in forests quickly and accurately. Our solutions help forest managers, environmental agencies, and communities monitor outbreaks and respond before damage becomes irreversible.

Why Use Remote Sensing to Detect Insect Damage?
???? Early identification of outbreaks before full-scale tree death
???? Differentiate insect damage from other disturbances (e.g., drought or fire)
????️ Monitor inaccessible and large forested areas cost-effectively
???? Track the progression and impact of pest infestations over time
✅ Support decision-making for targeted control and forest recovery

How Neftaly Detects Insect-Induced Forest Damage
✅ 1. Spectral Change Detection
Use satellite and drone imagery (Sentinel-2, Landsat, PlanetScope, drones)
Apply vegetation indices sensitive to stress, including:
NDVI (Normalized Difference Vegetation Index)
RENDVI (Red Edge NDVI)
MSI (Moisture Stress Index)
Detect leaf discoloration, defoliation, and reduced photosynthetic activity
✅ 2. Time-Series Monitoring
Compare pre- and post-infestation imagery over weeks, months, or years
Identify outbreak progression and forest canopy loss trends
Analyze seasonal insect activity patterns
✅ 3. Mapping Damage Intensity and Distribution
Classify affected zones into severity levels (low, moderate, high)
Generate geospatial maps showing hotspots and outbreak edges
Monitor regeneration or secondary damage (e.g., fungal infections after pest attack)
✅ 4. Integrating Field Data and Drone Surveys
Validate satellite results with field surveys and high-resolution drone imagery
Calibrate models to distinguish insect damage from storm or fire-related stress
Build a localized early warning and reporting system

Case Study: Monitoring Insect Damage in Sub-Saharan Woodland Forests
Neftaly supported a national forest agency to:
Detect early signs of caterpillar-induced defoliation in over 15,000 hectares
Identify NDVI drops of over 20% in severely affected zones within two months
Guide pest response teams to targeted areas using outbreak heatmaps
Monitor post-outbreak recovery and advise on replanting where needed
