Abstract

Bu çalışma, Nijer Eyaleti, New Bussa, Federal Yaban Hayatı Yönetimi Koleji'ndeki ağaç türlerinin çeşitliliğini ve bolluğunu değerlendirmek için yapılmıştır. Ormanlık alanda 50x50m (3 hektar) boyutunda on iki dikdörtgen örnek parselin envanteri çıkarılmıştır. Hektar başına, 18 familya ait 41 türe ilişkin 273 ağaç kaydedilmiştir. Anogeissus leiocarpus, çalışma alanında en bol bulunan ağaç türüdür. Toplam taban alanı hektar başına 11.42m2 olarak hesaplanmıştır. Sterculia setigera; 51.29 cm ile en yüksek ortalama göğüs çapına sahip iken, en yüksek ortalama boy 14.87 m ile Daniellia oliveri için kaydedilmiştir. Shannon-Weiner çeşitlilik indeksi (H) değeri 3.14 olarak hesaplandı. Maksimum çeşitlilik indeksi (Hmax) 5.61, Pielou tür düzgünlük indeksi (EH) 0.56 ve Margalef tür zenginliği indeksi (M) 7.13 olarak hesaplanmıştır. Etkili koruma programları ile çalışma alanındaki ağaçların sürekli mevcudiyetinin sağlanmasına ihtiyaç vardır.

Diversity and abundance of tree species of a protected woodland: Southern Guinea savanna zone (Nigeria)

Abstract

The study was carried out to assess the diversity and abundance of tree species in Federal College of Wildlife Management, New Bussa, Niger State. Twelve rectangular sample plots of 50x50m (3 hectares) were inventoried in the woodland. 273 trees per hectare were recorded, which belonged to 41 species and 18 families. Anogeissus leiocarpus was the most abundant tree species in the study area. The total basal area was 11.42m2 per hectare. Sterculia setigera had the highest mean diameter at breast height at 51.29 cm while the highest mean height of 14.87 m was recorded for Daniellia oliveri. Shannon-Weiner diversity index (H) value was 3.14. Maximum diversity index (Hmax) was estimated to be 5.61, Pielou’s species evenness index (EH) was 0.56 and Margalef’s index of species richness (M) was calculated to be 7.13. There is need to ensure continuous availability of trees in the study area through effective conservation programme.
