The influence of thinning on the leaf area index of pure oriental beech stands

Year 2018, Volume: 20 Issue: 3, 590 - 598, 15.12.2018

Abstract

Thinning is one of the most important
silvicultural interventions used in forestry operations. The general purpose of
thinning is to produce high-quality individuals with thick trunks without
permanently disrupting the density and closure of the stands. Thinning that
influences the frequency pattern of the trees and stand density can therefore
affect the leaf area index (LAI) of the stand. The LAI plays a key role in the
understanding of the ecosystem processes of many forests, e.g., in the areas of
health, productivity, interception, transpiration, respiration and net
production. The aim of this study is to investigate the effects of different
thinning intensities on the LAI in two pure oriental beech (Fagus orientalis Lipsky) stands in Düzce.
Before the thinning, the number of trees in the stands was 1371–3072 ha-1, the
average diameter at breast height was 10–14 cm and the basal area was 25.2–29.6
m2 ha-1. With the thinning, 0% (control), 27% (moderate)
and 40% (heavy) of the basal area were removed. Hemispherical digital
photographs were taken at five different locations in each parcel before and
after the thinning. In order to obtain the LAI values, the digital images were
analyzed via the HemiView V2.1 (Delta-T Device, UK) package program. It was
determined that the pre-thinning LAI had changed by between 3.37 and 5.14 m2
m-2. The LAI, having declined considerably with the heavy thinning
intensity, attained its initial value uninterrupted 3-4 years later. As a
result, according to the intensity of the thinning, the beech stands were able
to regain their initial LAI values in a short period of time, depending on the
precipitation. This can be explained by the fact that the remaining tree crowns
expanded and produced more leaves.

Doğu Kayını Meşcerelerinde Aralamanın Yaprak Alan İndeksine Etkisi

Year 2018, Volume: 20 Issue: 3, 590 - 598, 15.12.2018

Abstract

Aralama, ormanların işletilmesinde kullanılan en önemli silvikültürel
müdahalelerden biridir. Aralamalardaki genel amaç meşcere sıklığı ve
kapalılığını kalıcı şekilde kırmadan kaliteli ve kalın çaplı gövdeye sahip
bireylerin üretilmesidir. Meşcere kapalılığı ve sıklığı üzerinde etkili olan
aralamalar meşcerenin yaprak alan indeksi (YAİ)’nide etkileyebilmektedir. YAİ
meşcere sağlığı, verimlilik, intersepsiyon, transpirasyon, solunum ve net
üretim gibi birçok orman ekosistem sürecinin anlaşılmasında anahtar rol oynamaktadır.
Bu çalışmanın amacı Düzce yöresindeki iki ayrı saf doğu kayını (Fagus orientalis Lipsky) meşcerelerinde
uygulanan üç farklı aralama şiddetinin YAİ’ne etkisini araştırmaktır. Aralama
öncesi meşceredeki birey sayısı 1371-3072 adet ha-1, ortalama göğüs yüksekliği
çapı 10-14 cm ve meşcere göğüs yüzeyi (GY) 25.2-29.6 m2 ha-1 dır. Aralama ile
GY’nin %0’ı (kontrol), %27’si (mutedil) ve %40’ı (kuvvetli) meşcereden
çıkartılmıştır. Aralama öncesinde ve aralama sonrası denemelerin her parselinde
beş farklı noktada yerden ağaçların tepesine doğru yarı küresel dijital
fotoğraflar çekildi. Dijital fotoğraflar HemiView V2.1 (Delta-T Device,
İngiltere) paket programında analiz edilerek YAİ değerleri elde edildi. Aralama
öncesi YAİ 3.37-5.14 m2 m-2 arasında değişmektedir. Kuvvetli işlemde aralamayla
önemli ölçüde azalan YAİ, aralamadan 3-4 yıl sonra başlangıç değerine ulaştı.
Sonuç olarak, aralama şiddetine göre azalan YAİ, yağışa da bağlı olarak, kısa
süre içerisinde eski değerine ulaşabilmektedir. Bu kalan ağaçların daha fazla
tepe tacı yayması ve yaprak üretmesiyle açıklanabilir.
