The Determination of biological independence reazhing ages in natural mixed brutian pine(Pinus brutia Ten.)and Aanatolian Black Pine [Pinus nigra Arnold. subsp. pallasiana (Lamb.) holmboe] stands of Isparta Regional Forestry Directorate

The aim of this study at the same time with a master's thesis investigated growth characteristics creating a base to regeneration of natural mixed stands of brutian pine and Anatolian black pine stand should be passed on to future generations. This mixed stands of two different species that growth characteristic and the light requirements be considered as pure stands in the same year are brought into the area of youth and these species which are different growth performance and light requirements are often unable to compete in their habitat and mixed stands are transformed pure stands. If you type enough of the youth until the slow growth is possible given the age and size advantage, it will return the stands mixed stands of pure, forestry practices wherever possible, be maintained at the desired mixed stands. Other purpose, in mixed stands of the red pine that fast growing in the youth and light-tree with Anatolian black pine that half the light tree and slowgrowing in youth from brutian pine are exhibited of size field (cluster, group, large group or multiple large group) that species can be brought in regeneration methods that possible clusters, groups or large groups. By the second objective is to performance-oriented in the mixed stands of brutian pine-Anatolian black pine stands, to be created methods and information for small regeneration which orientation of world forestry for regeneration work methods.Isparta Regional Forestry Directorate where in the Lakes Region is cover all of Burdur, Isparta and a piece of Afyon. Study area is quite extensive and shows the variability from altitude, aspect, slope and site index class, so we can investigation that mixed stands the different conditions have occurred. Indeed, within the boundaries of the Isparta Regional Forestry Directorate in different mixing ratio, diameter class, stand closure, age, stage and site of the class of natural mixed stands of brutian pine and Anatolian black pine covers 15 466 ha area. Samplings for the aims of project can be carrying out will be this mixed stands. The basic approach in the project is to ensure adequate distribution of samples trees that different site indexes, aspects (light and shadow) and slope groups in brutian pine and Anatolian viblack pine mixed stands. In this context, age of biological independence (length=50, 75 and 100 cm) reach at least 600 trees will be determined to per 15 from different characteristics stands of each species. In additional leader of exploited and not being able to exploit the qualities advance reproductions at brutian pine and Anatolian black pine will be primarily determined, then, can be useful in leading the advance reproduction groups and advance reproduction rates change according to group size, this ratio will be reviewed. For this purpose, to 5 for each type of grain to various site index, aspect and slope in group a total 30 advance reproductiongroups leader and size of groups could be exploited if the youth will be revealed.Professionals who worked in The General Directorate of Turkish Forestry (OGM) will benefit from information that ?period of reaching biological independence on species? to be obtained at the species, site index and age classes and will be used regeneration method of should be application brutian pine and Anatolian black pine natural mixed stands. Additionally, the lead will be for studies of the other mixed stands by natural regeneration methods applied in the natural regeneration of mixed stands is revealed awareness of error.When the project is carried, the solutions are produced for the natural regeneration which big problem of brutian pine Anatolian black pine mixed natural stands in our country and multiple losses encountered for mixed stands regeneration will be avoided.
