forest types mapping, is one of the most necessary elements in the forest management and silviculture treatments. traditional methods such as field surveys are almost time-consuming and cost-intensive. improvements in remote sensing data sources and classification –estimation methods are preparing new opportunities for obtaining more accurate forest biophysical attributes maps. this research co...

Ecological phenomena are evident over a broad spectrum of space and time scales. Ecotones, being defined as zones of transition between adjacent ecological systems, also must occur over an equally broad spectrum of space and time scales. Scale-dependent constraints influence ecological phenomena and resulting zones of transition; however, in traditional ecotone studies little treatment has been...

This paper presents results of analyzing the second half 20th–early 21st century changes in lateral spatial structure Larix sibirica Ledeb. population upper treeline ecotone located on Rai-Iz massif (Polar Urals, Russia). The GIS layers characterizing distribution Siberian larch trees and undergrowth together with their crowns was produced for a 7.32 square kilometer area based aerial images re...

Height-diameter relationship is one of the most important stature characteristics of trees. It will change with climatic conditions because height and diameter growth displays different sensitivities to climatic factors such as temperature. Detecting and understanding changes in the stature of trees growing along altitudinal gradients up to their upper limits can help us to better understand th...

Changes in vegetation height the boreal-alpine ecotone are expected over coming decades due to climate change. Previous studies have shown that subtle changes (<0.2 m) can be estimated with great precision short time periods (~5 yrs) for small spatial units (~1 ha) utilizing bi-temporal airborne laser scanning (ALS) data, which is promising operation monitoring. However, ALS data may not alw...
