Abstract

Creep is a flow type of mass movement that may proceed as slowly as a few millimeters per year; it therefore requires measurements taken over many years to calculate its velocity. Although soil creep occurs very slowly, it is a major contributor to river silt, and may also enhance landslides. This...

Abstract

Observational and quantitative ring width characteristics of 4 pine species i.e., 1. Abies pindrow, 2. Cedrus deodara, 3. Pinus wallichiana, 4. Pinus roxburghii from highly disturbed sites of Murree Hills were studied. From each pine tree species wood (cores) samples were collected, prepared in the ...

Abstract

The study was carried out to describe the pine communities at Indus Kohistan valley in quantitative term. Thirty stands of relatively undisturbed vegetation were selected for sampling. Quantitative sampling was carried out by Point Centered Quarter (PCQ) method. Seven tree species were common in...

Abstract

The climate/growth relationships of four gymnosperm tree species growing in seven catchments in the Indus Basin of the Karakorum range, North Pakistan, were evaluated for using two versions of tree-ring chronologies: "standard" and "residual" chronology. The growth of the trees was compared to...

Abstract

Ring-width chronology of 211 years (AD 1730-2010) was developed using Himalayan Pine (Pinus wallichiana) collected from Ganji Skardu mono-specific Pinus wallichiana forest near the mix forest of Pinus wallichiana, Juniperus excelsa and Betula utilis on different aspect and slope angle. Chronology...

Abstract

Standardized ring-width chronologies of Pinus wallichiana A.B. Jackson and Pinus gerardiana Wall. ex Lamb., are presented, covering maximum period from AD 1300-2000 and 1400-2000 AD respectively. These chronologies are based on highly correlated (0.636) and crossmatchable wood samples. Response...
