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

Pinus wallichiana dominated forest communities, located in the Hindukush ranges of Swat, Pakistan were analysed for variability in the cone and seed traits. The results disclosed significant variability in mean values, critical difference, co-efficient of variation, broad sense heritability,...

Abstract

Dendrochronological studies were conducted in 40 different sites in conifer dominated forests from Shangla District, Khyber Pakhtunkhwa Province, Pakistan. Wood samples in the form of cores were obtained by using Swedish increment borers including Pinus wallichiana A.B Jackson, Abies pindrow Royle, ...

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

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

We investigated the phytosociology, structure and dynamics of Pinus roxburghii in 40 stands in northern areas of Pakistan by using cluster analysis (Ward's agglomerative clustering) and ordination (Nonmetric Multidimensional Scaling). Cluster analysis revealed three major groups associated with...

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

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

A collection of 28 tree-ring chronologies from six different species located in northern Pakistan were evaluated in terms of their potential for dendroclimatic reconstructions. 15 of the sites are new while the remaining 13 (all Juniperus excelsa M. Bieb.) have been reported earlier. Several...
