Abstract

The purpose of this study was to determine the relationships between soil moisture and backscattering coefficient values calculated for each sampling plot and compare with soil moisture in different forest sites and crown closure classes using Radarsat satellite images in Artvin-Merkez and Gumushane-Karanlikdere forest planning units. Results indicate that in low coverage and degraded forest areas in dry and fresh-moderate fresh forest sites in Artvin forest planning unit, the relations between soil moisture and backscatter coefficient values were negatively correlated with r=-0.85 and r=-0.73, respectively. However, there was no relationship between backscatter coefficient values and soil moisture in medium crown coverage and full coverage stands. Similarly, at low coverage and degraded forest areas in very dry-dry and fresh-moderate fresh forest sites in Gumushane-Karanlikdere forest planning unit were positively correlated high and significant r=0.78 and r=0.83, respectively.
