Investigation of fallow deer (Cervus dama L.) population densities by camera trap method in Antalya Düzlerçamı Eşenadası Breeding Station

Abstract

In Turkey, it has been aimed to take a number of measures to protect and breed fallow deer, which is under danger of reduction of population, even extinction. One of these measures is Antalya Düzlerçamı Eşenadası Fallow Deer Breeding Station (EFDBS). Fallow deer is protected in this area, where measures and improvements are taken to the maximum for breeding fallow deer in its natural environment. 55 out of 170 mammal species are critically endangered in Turkey, and one of these is fallow deer (Cervus dama L.). This study aims to investigate the population densities of individuals spread in the EFDBS at Antalya Düzlerçamı Wildlife Development Area with 521 ha of land using the method of camera traps. Density calculations were made using the method of individual identification based on spot distribution and antler structure of individuals. The information provided by the Jackknife Model was used to determine population densities. “CAPTURE” software was used for the analysis of the data. Based on the obtained results, maximum of 120, minimum of 96 and average of 105 fallow deer individuals were found. According to these results, fallow deer population density was 20.1/km2 in the study area.

Antalya Düzlerçamı Eşenadası Alageyik Üretim İstasyonu’nda fotokapan yöntemiyle alageyik (Cervus dama L.) popülasyon yoğunluklarının araştırılması

Abstract

Ülkemizde, nesli bu denli azalma hatta yok olma seviyesine gerileyen alageyik için bir takım koruma ve üretme tedbirleri alınmak istenmiştir. Bunlardan bir tanesi, Antalya Düzlerçamı Yaban Hayatı Geliştirme Sahasında kurulan Eşenadası Alageyik Üretme İstasyonu’dur. Alageyikler bu alanda koruma altında olup, doğal ortamında üremesine yönelik maksimum önlemlerin ve iyileştirmelerin yapıldığı bir alandır. Ülkemizde yaşadığı saptanan 170 memeli türden 55’inin nesli önemli ölçüde tükenme tehdidi altında olup, bunların en önemlilerinden bir tanesi alageyik (Cervus dama L.)’dir. Bu araştırmada, fotokapan yöntemi ile 521 ha alana sahip Antalya Düzlerçamı Yaban Hayatı Geliştirme Sahasında bulunan Eşenadası Alageyik Üretme İstasyonu içerisinde yayılış gösteren bireylerin popülasyon yoğunluklarının araştırılması hedeflenmiştir. Yoğunluk hesaplamaları, bireylerin benek dizilişinden ve boynuz yapısından birey tespiti yöntemi kullanılarak yapılmıştır. Verilerin analizi için “Capture” bilgisayar programından faydalanılmıştır. Populasyon yoğunluğunun belirlenmesi için Jackknife Model verileri dikkate alınmıştır. Elde edilen sonuçlara göre maksimum 120 birey, minimum 96 ve ortalama 105 Alageyik tespit edilmiştir. Elde edilen bu sonuçlara göre çalışma alanında alageyik populasyon yoğunluğu 20,1/km2 dir.
