Remote Sensing of Relative Moisture Status in Old Growth Douglas-fir
نویسنده
چکیده
Comparison of the historical and spatial precipitation and tree growth patterns confirm that one of the limiting conditions to growth on southern Vancouver Island is moisture, both as it relates to precipitation as well as the position of the tree within the slope catena. Comparison of tree growth patterns with AVIRIS reflectance indicates that there is correlation between the growth increment and the reflected. Detailed analyses also indicates a wavelength dependent relationship existing between tree growth and reflectance. These trends are supported by the multitemporal AVIRIS data where variations in mean annual precipitation yield significant variations in reflectance.

Soil Moisture Estimation in Rangelands Using Remote Sensing (Case Study: Malayer, West of Iran)
Soil moisture is generally regarded as the limiting factors in rangeland production. Although many studies have been conducted to estimate soil moisture in semiarid areas, there is little information on mountainous rangelands in west of Iran. The present study aims to investigate the soil moisture estimation in rangelands as compared to the other land uses over a mountainous area in central Zag...

متن کاملMoisture Stress and Root Volume Influence Transplant Shock: Preliminary Results
-Despite evidence of its economic impact, very little is known about transplant shock. This study was designed to evaluate transplant shock in relation to root volume and soil water content for two year-old Douglas-fir seedlings. Preliminary results found that new growth decreased and days to budbreak increased with higher moisture stress. This effect was most pronounced for high root volume se...
