Climate change will affect all ecosystem services of green areas in the districts. In many cases, the tree species in parks and districts are suffering from the increasingly warmer and drier summers and newly immigrated pests and diseases. Tilia tomentosa Moench. is considered as an important tree species under climate change for dry and warm conditions in Central and Southeastern Europe countries. This tree species is often used as valued urban tree. In the present study we investigate the growth patterns of T. tomentosa Moench. in relation to their growing conditions in order to evaluate its interactions in urban contexts. All the studied characters varied significantly among the sampled districts. Within each of the regions, number of flowers showed a wide range 72-104 per m2 in Marmara region and 54-124 per m2 in Western Black Sea region. All studied characters, beyond number of flowers, positively correlated with each other. This study revealed that especially fruit length had a strong and positive correlation with altitude and a high negative correlation with temperature. Further researches are required to quantify more growth flower characters of the species from Turkey.
Juniperus L. for Restoration of Degraded Forest Lands in Turkey
(2021-01-01) Yücedağ C.; Ayan S.; Farhat P.; Özel H.B.
Degraded forests are among of the most important environmental and commercial problems around the world. Turkey has 22.74 million hectares of forest area, out of which 9.656 million ha (42%) are unproductive. To transform these unproductive forests into productive ones, forest restoration including rehabilitation is one of the best actions. In this sense, juniper species play an important role for degraded lands because they are drought-tolerant and withstand aridity and poor soils better than most timber species grown in Turkey. Therefore, this review presents the ecological considerations for the restoration of degraded forest lands in Turkey under the conditions of climate change. Within this framework, it focuses on the production of planting stock of juniper species, the significance of site-species matching, and post-planting site maintenance for successful rehabilitation.
