Protected areas’ chief conservation objectives are to include species within their boundaries and protect them from negative external pressures. Many protected areas are not achieving these goals, perhaps in part due to land development inside and outside protected areas. We conducted spatial analyses to evaluate the ability of Canadian protected areas to mitigate the effects of nearby land development. We investigated correlations of national patterns of land development in and around protected areas and then examined national patterns of roads, urban area, and croplands in protected areas. We calculated the amount of developed land in protected areas and within 25–100 km of protected‐area borders, the density of roads, and extent of urban and cropland area in protected areas. We constructed logistic‐regression models to test whether development in a protected area was associated with landscape and protected‐area characteristics. Land development was far less extensive inside than outside protected areas. However, several protected areas, particularly small southern areas near small urban centers had substantial development inside their boundaries, and nearly half of protected areas had roads. The cumulative extent of development within 50 km of protected areas was the best predictor of the probability of land development in protected areas. Canadian First Nations, industries, government, and nongovernmental organizations are currently planning an unprecedented number of new protected areas. Careful management of areas beyond protected‐area boundaries may prove critical to meeting their long‐term conservation objectives.

The study was carried out in the Altindere Valley, which is an area appropriate for tourism activities with natural, historical and cultural values through all four seasons, with Yazlik Village in the centre and including the surrounding sites Cosandere village, Altindere village, hamlets (The Hamlets) and plateau areas. In this study, the goal is to set forth the ecological-based tourism potential in line with the concepts of intactness; conservation-use balance; and sustainability at natural, historical and cultural sites through a determined planning approach. In this respect, assessments have been made on the study area on the basis of the ‘Ecological Evaluation Method’, which has been developed for urban areas. Through the determination of quotients, classification and quantitative assessment of unweighted values were found for natural and cultural elements that show percentage (%) dispersion at the area (slope, exposition, soil, forest, vegetation, existing areas use, historical and cultural structure). ‘Weighted values’ were calculated by multiplying the determined factor weights and the unweighted inside grid values of the factors. With the results of grid values obtained, 10.58% Very Good, 48.82% Good, 19.7% Average, 8.82% Weak, and 12.05% Very Weak, ‘Ecological Based Tourism Potential Areas According to Natural, Historical and Cultural Factors’ have been identified.  相似文献
