Opis:
The main aim of the study was to compare the radial growth of Persian walnut and Schrenk spruce trees growing under the same ecological conditions in the Sary-Chelek range of the Tien-Shan Mountains, as well as to analyse the response of these species to the selected climate factors in line with the altitude gradient. Four study plots were established at the altitude of 1350, 1400, 1450 and 1500 m a.s.l. Results indicated that (1) walnut and spruce in the Sary-Chelek Biosphere Reserve have different patterns of radial increment and reaction to climate factors, despite growing in the same habitat, (2) spruce radial growth responded to low precipitation and low temperature during the April to September period of the previous year; (3) walnut radial increment patterns varied significantly with changes in altitude, whereas spruce patterns did not; and (4) walnut radial increment patterns responded positively to high temperature during contemporary growing season and to precipitation during the prior growing season. In addition, it was noted that precipitation during the contemporary growing season could negatively influence growth.

Opis:
Ongoing climate change will likely expose trees and forests to new stresses and disturbances during this century. Trees naturally adapt to changes in climate, but their natural adaptive ability may be compromised by the rapid changes projected for this century. In the broad sense, adaptation to climate change also includes the purposeful adaptation of human systems, which includes forestry. In this article, we briefly review the expected impacts of projected climate change on trees and forest ecosystems in Poland. We further provide a framework for designing adaptive strategies to sustain or enhance forest growth, health, and ecosystem services in new climates. Within this framework, we distinguish two related objectives: (1) adaptation of decision−making process in forest management and (2) adaptation of forest ecosystems. Each of these objectives may be achieved through strategies and options whose applicability is discussed in relation to major forest functions – ecological and societal, commercial, and multiple−use. Knowledge gaps and research needs are also identified. We conclude that the recent emphasis on sustainable multifunctional forestry and the current ownership structure in Poland will facilitate adaptation of Polish forests to future climates. However, much remains to be learned about the impacts of climate change, especially at the ecosystem level. Cooperation between researchers and forest managers is critical for developing better management strategies for adapting forests to climate change.
