Yol ağları, orman ekosistemleri üzerinde
habitatların bozulması ve parçalanması gibi önemli etkilere sahiptir. Öte
yandan, yol kenarı boyunca ışık mevcudiyetinde görülen artış, bitki türlerinin
çeşitliliğine ve miktarını da yansımaktadır. Bu çalışmada, yol kenar etkisinin
ağaçların büyümesi üzerindeki etkisini araştırmak amacıyla Ihlamur meşceresinde
bulunan örnek bir yol ağı boyunca ağaç çaplarındaki değişim ölçülmüştür.
Çalışma, Ihlamurun Türkiye’de en geniş yayılış gösterdiği Bursa’nın Karacabey
ilçesinde gerçekleştirilmiştir. Arazi verileri yol kenarındaki 5 metre
genişliğindeki şeritlerden seçilen ve yol kenarından uzakta kontrol bölgesinden
seçilen örnek ağaçlardan toplanmıştır. Verilerin toplanması sırasında belirlenen
bölgelerdeki tüm örnek ağaçların göğüs yüksekliği çapı ölçülmüş ve artım
burgusu ile artım kalemleri alınmıştır. Daha sonra, yol kenarındaki ağaçlar ile
kontrol bölgesinde yer alan ağaçlar arasında çap ve çap artımı değerlerinde bir
farklılık olup olmadığını belirlemek için istatistiksel analiz yapılmıştır.
Sonuçlara göre, yol kenarından olan mesafenin arttırılmasıyla, ortalama ağaç
çaplarında ve çap artımı değerlerinde azalma görülmüştür. Yol kenarındaki
ağaçlar ve kontrol bölgesinde yer alan ağaçlar arasında çap değerleri açısından
istatistiksel olarak anlamlı bir fark bulunmuştur. Öte yandan, çap artım
değerleri arasında anlamlı bir fark tespit edilmemiştir.

Abstract
DOI: 10.26650/forestist.2019.18014
Roads have important effects on forest
ecosystems including degradation and fragmentation of habitats. However, light
availability along the road edge increases which reflects the diversity and
amount of plant species. This study is aimed to investigate the road edge
effect on tree growing by measuring the differentiation of tree diameters along
a sample road located within Linden stands. The study was conducted in
Karacabey province of Bursa where Linden has the largest distribution in
Turkey. Field data were collected from sample trees selected from 5-meter-wide
stripes at road edge and from control zone away from road edge. The tree
diameters at breast height (DBH) and trunk core samples were collected from
sample trees located in the specified zones. Statistical analysis was conducted
to indicate whether there is a differences in DBH and DBH growth values between
trees at road edge and ones at control zone. The results indicated that
increasing distance from road edge resulted in reduction in the average tree
diameters as well as DBH growth values. There was a statistically significant
difference between DBH values for trees at road edge and ones at control zone.
On the other hand, there was no significant difference between DBH growth
values.
