Примена географског информационог система при бонитирању ловишта у ловном туризму / Primena geografskog informacionog sistema pri bonitiranju lovišta u lovnom turizmu / Application of geographic information system in hunting ground habitat factors evaluation in Hunting tourism

Kovačević Milutin 09 July 2018 (has links)
<p>Услови који владају у одређеном станишту дивљачи (ловишту) зависе од многих фактора. Ти фактори су храна, вода, тло, вегетација, мир у ловишту, клима и др. Основни предуслов одрживог газдовања ловиштем је и адекватна оцена свих фактора. То се ради у поступку бонитирања на основу чега се даље раде пројекције капацитета ловишта. У основи ове докторске дисертације је да у процес бонитирања укључи географске информационе системе. То подразумева приказ новог метода бонитирања који би користио ГИС. У оквиру дисертације је приказана методологија методе бонитирања применом ГИС-а, као и његова примена у истраживаном подручју - равничарском ловишту &bdquo;Капетански рит&ldquo; Кањижа. На крају су презентовани резултати о анализи и оцени сваког од фактора, као и о могућој примениприликом утврђивања капацитета ловишта.</p> / <p>Uslovi koji vladaju u određenom staništu divljači (lovištu) zavise od mnogih faktora.

Recent researches have determined that available food, land cover, human&nbsp; disturbance, topography and climatic factors are essential factors. Its analysis is necessary for sustainable management of natural areas, including hunting grounds as game habitat. Hunting is an activity that is closely associated with forestry, water management, agriculture, tourism, etc. GIS is widely applied in the above-mentioned&nbsp; activities and therefore in the field of hunting. Past practice has shown that the classical methods for evaluating habitat factors involve a lot of subjectivity and often leads to unrealistic determination of hunting ground capacity. The aim of this dissertation is to assess evaluation of the essential factors fordetermination the capacity of hunting ground. Instead of the classical analyses, project proposes assessment of this factor using Geographic Information System (GIS) which have never been used for this purpose in hunting ground before. Researched area was hunting ground &ldquo;Kapetanski rit&rdquo; &ndash; Kanjiža, Serbia. Comparing classical methods for evaluating habitat factors and use of GIS for this purposes, obtained results indicate to adventages of new imrpoved GIS methodology<br />&nbsp;</p>

Critique of a Wildlife Habitat Evaluation Method Applied to Residential Open Space

Rigard, Sarah 01 May 2010 (has links)
To this date, little research has been done evaluating the quality of wildlife habitat provided by open space in residential areas. Quality wildlife habitat for the purposes of this study is defined as those areas which contain the physical and biological characteristics necessary to support native wildlife species of the region. This thesis critiqued a wildlife habitat assessment method used in a nationwide study of residential open space for the purpose of better understanding the research conducted by the study and to inform similar, future habitat evaluations of landscapes altered by human activity to accommodate residential land use. The methodology critiqued was a low resolution, habitat based, rapid assessment. The methodology provided information on the ecological function of the open space in each development and related that information to individual wildlife species needs to provide an estimation of habitat quality. However, an increase in sampling frequency and additional data collection would have improved the assessment.
