Development of diameter- height models for stone pine (Pinus pinea L.) stands in Tarsus region
In this study, diameter- height (d-h) models for afforestation stone pine (Pinus pinea L.) stands in Tarsus region were developed using the breast height diameter and tree height. The stonepine stand is about 932 ha and was planted in 1980. This study, a total of 20 models, the data used were obtain...

| description | In this study, diameter- height (d-h) models for afforestation stone pine (Pinus pinea L.) stands in Tarsus region were developed using the breast height diameter and tree height. The stonepine stand is about 932 ha and was planted in 1980. This study, a total of 20 models, the data used were obtained from 259 sample plots (n=5885) were tested. The available data for the species were split into two sets: the majority (%80) was used to estimate model parameters, and the remaining data (%20) were reserved to validate the models. The performance of the two (n=7), three (n=10) or four parameter models (n=3) was compared and evaluated with six model performance criteria. According to the model performance criteria, the best results were obtained with Prodan, Sibbesen and Ratkowsky models, respectively. The similar results were obtained using independent dataset. As a result, regional diameter- height models were created for stone pine. |
