Öğe Assessing the effects of long-term recreational activities on landscape changes in Abant Natural Park, Turkey(Northeast Forestry Univ, 2016) Çakır, Günay; Müderrisoğlu, Haldun; Kaya, Latif GürkanNatural, protected areas offer many possibilities for recreation in rural areas such as camping, one of the most popular activities. The system established for protected areas in Turkey aims to provide a foundation for conserving areas for recreation. One such area, Abant Natural Park, is convenient for visits from Turkey's two most populated metropolitan areas, Istanbul and Ankara. It also attracts tourists from other regions and countries. The aim of the present study was to evaluate the vegetation loss and land cover changes due to picnic/camping, transhumance, and construction over 40 years (1966-2004) in the park using data on visitor numbers, vegetation patches, corridors and connectivity. For evaluating landscape variables, remote sensing data and aerial photos were used. When aerial photos were imported into the ERDAS Imagine program, ground control points identified, and individual images orthorectified, land degradation was not found in the use of camping areas. Moreover, manmade areas (road, car park and hotel) observably increased, thus decreasing the forest lands. The findings show that the land use types that have had the greatest ecological impact are transhumance and construction of hotels, which also require infrastructure development. The intensity of the ecological effects mandates precautions to lessen the impacts and the need for continuing assessment to ensure sustainable use of the area.Öğe Attitudes and behaviors of undergraduate students toward environmental issues(Ctr Environment & Energy Research & Studies, 2011) Müderrisoğlu, Haldun; Altanlar, AslıThe studies carried out throughout the world have indicated that there are differences between environmental attitudes and environmentally responsible behaviors of undergraduate students. In what ways the environmental attitudes and behaviors of the students who will protect and manage the resources of the country in the future have changed is an important issue? This study was aimed at determining the environmental attitudes and environmentally responsible behaviors of the undergraduate students of Abant Yzzet Baysal University toward environmental issues. In addition, the effects of the faculty in which the students are enrolled, locality and gender on the determined environmental attitudes and environmentally responsible behaviors of the students were investigated. The data were gathered from 507 students in 2005. To explain the environmental attitudes and environmentally responsible behaviors of undergraduate students toward environmental issues, factor analysis was used with Varimax Rotation method. To determine the changes of the environmental attitudes and environmentally responsible behaviors of the students with regard to the faculty, locality and gender, one-way analysis of variance was used. According to the results, students highly support the environmental attitudes and highly participate only in consumerism behaviors. Finally, it was determined if faculty and gender had an effect on the environmental attitudes and behaviors of the students.Öğe Bolu Gölcük’teki doğal ve egzotik sucul bitki türleri için risk yönetimi planı(2023) Aksoy, Necmi; Güneş Özkan, Neval; Koçer, Nihan; Müderrisoğlu, Haldun; Eroğlu, EnginBu çalışma Bolu Gölcük Gölü Tabiat Parkı için göl içerisinde bulunan istilacı ve yabancı türlerle ilgili eylem planının hazırlanması kapsamında yapılmıştır.

However, data is scarce about management practices on user satisfaction. For the current study, a survey was conducted on 300 people to determine the user satisfaction related to management practices on the recreational areas. Study has been conducted in Mogan park, Ankara and coastal area of Mugada, Bartin. The results of questionary indicate that user's satisfaction has been affected by the management practices. However, data indicates that the users with experiences about the site are more satisfied with current management situation than the ones who do not have experiences about the site.Öğe THE EFFECT OF SEASONAL CHANGE OF PLANTS COMPOSITIONS ON VISUAL PERCEPTION(Vilnius Gediminas Tech Univ, 2012) Eroğlu, Engin; Müderrisoğlu, Haldun; Kesim, Güniz AkıncıPlants are important elements of open-green areas in the urban space and perception of an environment. Some plants have seasonal colour changes. The identification of these changes and clarification of the effects on people are quite important for landscape architecture. Seasonal changes of plants in some open-green areas in Duzce were examined in order to explain how it affects people regarding changes in perceptional preferences. Delphi Method was used on photographs as a mean of identification of the visual effects of the plant compositions. The plant composition photographs, which had been examined before, were used in the questionnaire to 370 student groups. As a result, the difference was evaluated between the perceiving of different plant compositions. Summer was the most affecting season having the design value and visual quality. Besides, evergreen plants had a positive effect on design power and visual quality of compositions. Furthermore, as another important result, it was found out that socio-economic levels of the people had some important effects on visual preferences. In this study, perceptional differences of the participants on seasonal changes of the plants were identified. Moreover, the form and the texture were evaluated for identifying perceptional effects.Öğe EFFECTS OF COLOURS AND FORMS OF TREES ON VISUAL PERCEPTIONS(Pakistan Botanical Soc, 2009) Müderrisoğlu, Haldun; Aydın, Şükran Özkan; Yerli, Özgür; Kutay, ElifThe objective of this study was to determine the effect of colour on the perception of tree forms and the effects of personal characteristics of the participants on their preferences. The students of science studies, medical science and social science of Duzce University, Turkey, participated in the study (n=159). The participants were asked to evaluate 5 different tree forms which were drawn by hand and coloured with 8 different colours by semantic differential method. According to the results obtained, pyramid-formed trees were preferred most and colour had a strong effect on the preferences of tree forms. Bright green trees were found to have the highest visual quality while blue-coloured trees the highest strength. Again, the results obtained in this study indicate that personal characteristics are effective on preferences of tree forms and colours.Öğe Effects of second housing and recreational use on Pancratium maritimum L. population in western Black Sea region of Turkey(Wfl Publ, 2010) Demir, Zeki; Müderrisoğlu, Haldun; Aksoy, Necmi; Aydın, Şükran Özkan; Uzun, Serir; Özkara, HüseyinAn experiment was conducted to investigate the effects of second housing development and heavy use recreational activities on sea daffodil (SD; Pancratium maritimum L.) distribution on western Black Sea coast line of Turkey. In 2005, to protect the SD populations 1 m height chicken wire-cages were placed on 20 m x 30 m areas in different parts of the shore. To compare the protected area (PA) with unprotected area (UA) 16 sampling areas were chosen along the coast line. Adjacent to each sampling plot a control plot from unprotected area was established. Additional data were collected from sampling plots established in four areas with different intensities of settlement. Data were utilized to relate the SD ground coverage, number of individuals and spikes per individual to the disturbance intensity. Three 1 m x 1 m quadrats were randomly placed on each plot. On each quadrat the ground coverage of SD and whole vegetation were determined with Braun-Blanquet. Then, the number of SD individuals and spikes of individuals were counted. Data indicated that there was no statistical difference between the PA and UA in vegetational ground coverage. However, the ratio of SD on these coverages was doubled in PA compared to the UA (P = 0.001). Analysis of the data collected from different locations in disturbed areas showed that intensity of disturbance has significant (P = 0.001) correlation with SD ground coverage (r(2)=0.45). The number of SD individuals (P = 0.001) and spikes per individual (P = 0.001) were significantly different between the PA and UA. SD individuals in UA were about 64% less than that of PA. Spike number per SD individual was also 66% lower in UA compared to PA. SD ground coverage was significantly (P = 0.001) related to number of individuals (r(2)=0.83). Settlement density made a significant effect on number of SD, number of spikes, SD ground coverage and whole plant ground coverage (P = 0.001). Analysis of data indicated that area usage type also made statistically significant differences on number of SD, number of spikes, SD ground coverage and whole plant ground coverage (P = 0.001). Results of the study indicate that SD populations are under threat because of intensive housing development and recreational usage in the coastal areas of Western Black Sea region of Turkey. Protection efforts revealed positive results in terms of SD survival and reproduction capacity in the coastal sand dunes.Öğe Effects of User Density Levels on Recreational Walking Experiences(Sage Publications Ltd, 2013) Müderrisoğlu, Haldun; Aydın, Şükran Özkan; Ak, Kıvanç; Eroğlu, EnginOver the past 25 years, attempts to increase the quality of visitor experiences have been a priority in outdoor recreational areas for planners and managers. Recreation planners should determine acceptable usage levels for an area before making planning decisions. Physical, economical, ecological and social carrying capacity of that area must be determined, in order to assess acceptable usage levels. In this study, the influence of the characteristics of the area on visitor perception of user density levels was evaluated. The activity of walking was chosen to determine the perception of the user density level. Walking was chosen because it is a recreational activity that can be performed easily and frequently by visitors of outdoor recreational areas without any need for experience. Factors affecting the perception and effects of the user density level on visitors were examined from urban recreational areas to rural recreational areas. According to our results, characteristics of the recreational area and changes in the perception of suitable user density levels varied according to the recreational activities performed in an area. Specifically, rural recreation users tolerated less user density. In contrast to the expected, female users preferred lower user density.Öğe An evaluation of green areas from the point of user satisfaction in Ankara, Turkey: Gap analyses method(Academic Journals, 2010) Müderrisoğlu, Haldun; Oğuz, Dicle; Şensoy, NihanGreen spaces contribute to the urban environment by producing positive ecological impacts and providing spaces for recreation and contact with nature. It is proven in various researches that urban green spaces and especially the parks increase the quality of life by presenting a variety of recreational experiences. Benefits and performances of green spaces are assessed by user satisfaction studies. This study aims to reveal the satisfaction level of users by using gap analyses method in significant green spaces of Ankara namely Altinpark, Genclik Parki, Goksu Parki, Harikalar Diyari and Mogan Park. In these daily used recreation areas, quality of service, important comments (importance) of the users prior to their visits and experiences after use (satisfaction) are evaluated by ranking. With this purpose a questionnaire survey is applied to 289 people in September and November 2009. The results show that in order to raise the satisfaction level of users, the number of entertainment areas should be increased and access to information services, park keepers and wards that can react immediately to the needs of the visitors should be provided.Öğe Kırsal rekreasyon alanlarında kullanıcı memnuniyeti: Bolu Gölcük Ormaiçi dinlenme yeri örneği(2010) Uzun, Serir; Müderrisoğlu, HaldunOrmaniçi dinlenme yerlerine son yıllarda artan bir ilgi ve talep bulunmaktadır.

Several research have demonstrated that environmental attitudes and behaviours of adults are formed according to their environmental experiences. Outdoor recreational activity preferences of a family could also have a substantial influence on landscape preferences of children. There has been little research that evaluate children's perception and about their playgrounds. Consideration of children's needs and their landscape preferences would be important for designing better play spaces. Photographs were used to determine naturalness degrees by specialists. These photographs were shown to 280 students attending elementary school, middle school and high school of different levels. Students were asked if the landscapes from the photographs were aesthetic pleasing and safe; and if they would accept them as playgrounds. The results indicated that the students would prefer the areas as playgrounds even though they may not find them safe. However, the majority of students regarded some of the landscapes were aesthetic and safe. The findings show that the students' ages, education levels and physical appearances could yield substantial differences on their landscape perception and preferences. The students would highly prefer the landscapes if they have been involved in rural recreational experiences which could have a substantial effect on their landscape perception and preferences.Öğe Visual impact assessment of the Istanbul Land-wall(SAGE Publications Ltd, 2019) Ögçe, Hüseyin; Müderrisoğlu, Haldun; Uzun, SerirVisual impact assessment studies are reasonably substantial to understand an environment which has different features. The aim of this study is to evaluate the visual impact of the Istanbul Land-wall and contribute to future design/planning stages. For this purpose, the study area was separated into four different spatial usages which are recreational, transportation, agricultural and neglected places. Twenty-four different photographs were taken and a survey was conducted upon an expert and a public sample group. The public survey included four parameters: well-kept, exciting, safety and beautiful scenery. The expert survey also involved four parameters which were coherence, imageability, stewardship and historicity. One-way ANOVA test was conducted to reveal sample groups’ effect on the preferences. The results showed that the average scores of photographs evaluated by public and experts were 11.07 and 9.80 scores respectively. In the public survey, the photograph, has the lowest scores for all parameters, was Photo-11 (P11). Experts’ result shows particularly that historicity is lower than the others although the area is a historical region. Specifically, neglected places obtained lower scores than the other spatial types. Consequently, the Istanbul Land-wall does not have adequate visual quality regarding the selected parameters. © The Author(s) 2019.Öğe Visual landscape quality in landscape planning: Examples of Kars and Ardahan cities in Turkey(Academic Journals, 2011) Uzun, Osman; Müderrisoğlu, HaldunTogether with European landscape convention, it is required that studies related to landscape planning should be integrated with the sectors such as department of urban and regional planning, industry, agriculture and forestry. Visual landscape analysis has an important position in landscape planning. In this study, it is aimed that a method for visual landscape quality which is one of the researches of landscape analysis is developed in a physical planning workout that is to be carried out in Kars and Ardahan. The data that is to represent the seven factors are: Landform, vegetation, water, color, influence of adjacent scenery, scarcity, cultural modifications, in practicing the visual source management method has been constructed in the environment of geographical information systems by making use of the databases of Ministry of Environment and Forestry and Corine land cover. The accuracy of visual landscape quality maps has been proved by practicing the method in site conditions and in twenty three different points. This situation proves that the method can safely be practiced in the studies such as sub-regional scales, planning and strategic environmental assessment.Öğe Yedigöller Milli Parkı, Kargalı Gölcük ve Göksu Tabiat Parklarındaki doğal sucul bitki türlerine yönelik tehditlerin belirlenmesi(2023) Aksoy, Necmi; Koçe, Nihan; Özkan, Neval Güneş; Müderrisoğlu, Haldun; Eroğlu, EnginBu çalışmanın amacı Bolu Yedigöller Milli Parkı ile Kargalı Gölcük ve Göksu Tabiat Parklarında bulunan sucul habitatlardaki bitki türlerinin izlenmesi ve tehditlerin belirlenmesidir. 2022 yılında yapılan arazi çalışmaları ile göller içerisinde ve kıyı alanlarında yayılış yapan doğal ve yabancı bitki taksonları belirlenmiştir.
