Connectivity is Vitally Important in a Fragmented Forest Ecosystem to Sustain Biodiversity: An Analysis for Rize

Öz:
Forests are the leading ecosystems that are under threat due to the pressure of global change. Being under pressure for a forest ecosystem means fragmented and isolated habitats, decrease in biodiversity and change in the landscape. In recent years, restoring landscape connectivity by minimising landscape fragmentation has been recognised as a key strategy to conserve biodiversity. Well-connected habitat networks are thought to both protect existing populations and help adaptation under climate change. It is therefore priority to understand how best to maintain and develop connectivity in fragmented landscapes at multiple spatial scales for effective conservation of forest biodiversity. In this study, fragmentation analysis was performed using area, edge, and isolation metrics in the forest matrix in the Rize landscape and connectivity corridors were interpreted to manage the impact of this fragmentation on species and habitats. The fragmentation analysis was carried out on 3 classes as broad-leaved, coniferous, and mixed using land cover/land use data with the years 1990-2018. The connectivity corridors between these classes were analysed using core area data and resistance maps. According to the results; it was observed that fragmentation in broad-leaved and coniferous classes and an increase in mixed forest class. In the connectivity analysis it was observed that the limiting effects arising from human activities increased more in 2018 compared to 1990. The results of this study showed that in a fragmented forest matrix, connectivity corridors can be identified and reconstructed the conditions necessary for the survival of biodiversity.

Parçalanmış Bir Orman Ekosisteminde Biyoçeşitliliği Desteklemek İçin Bağlantılılık Yaşamsal Bir Öneme Sahiptir: Rize İçin Bir Analiz

Öz:
Küresel değişim baskısı nedeniyle tehdit altında olan ekosistemlerin başında ormanlar yer almaktadır. Orman ekosisteminin baskı altında olması, parçalanmış ve izole olmuş habitatların oluşması, biyoçeşitliliğin azalması ve peyzajın değişmesi anlamına gelmektedir. Son yıllarda, peyzaj parçalanmasının en aza indirilerek peyzaj bağlantısının yeniden sağlanması, biyolojik çeşitliliği korumaya yönelik anahtar bir strateji olarak kabul görmüştür. Aralarında iyi bağlantı kuran habitat ağlarının hem mevcut popülasyonları koruduğu hem de iklim değişikliği altında adaptasyona yardımcı olduğu düşünülmektedir. Bu nedenle orman biyoçeşitliliğinin etkili bir şekilde korunması için birden çok mekȃnsal ölçekte parçalanmış peyzajlarda bağlantının en iyi nasıl korunacağını ve geliştirileceğini anlamak önceliklidir. Bu çalışmada, Rize peyzajındaki orman matrisinde alan, kenar ve izolasyon metrikleri kullanılarak parçalanma analizi yapılmış ve bu parçalanmanın türler ve habitatlar üzerindeki etkisini yönetmek amacıyla bağlantı koridorları yorumlanmıştır. Parçalanma analizi, 1990-2018 yıllarını kapsayan arazi örtüsü/arazi kullanımı verisi kullanılarak geniş yapraklı, iğne yapraklı ve karışık olmak üzere 3 sınıf üzerinde yapılmıştır. Bu sınıfların birbirleri arasındaki bağlantı koridorları ise çekirdek alan ve direnç haritaları kullanılarak analiz edilmiştir. Sonuçlara göre; geniş yapraklı ve iğne yapraklı orman sınıflarında parçalanma olduğu, karışık orman sınıfında ise artış olduğu gözlenmiştir. Bağlantılılık analizinde ise, insan faaliyetlerinden kaynaklanan sınırlayıcı etkilerin 1990 yılına göre 2018 yılında daha da arttığı gözlenmiştir. Bu çalışmanın sonuçları, parçalanmış bir orman matrisinin, bağlantı koridorları tespit edilerek biyolojik çeşitliliğin ve türlerin devamı için gerekli olan şartların yeniden yapılandırılabileceğini göstermiştir.
