Introduction: What conservation problem or question does your study address?
The reintroduction of Eastern Sarus Crane project of Thailand started since 2011 and successes in survival of the cranes now. this study, we focus on criteria and factors which support habitat selection of them after released back to nature for applied to the model of habitat suitability index (HSI). The result should be predicted the suitability wetlands which can be support to population of them and increased understanding of habitat relationships and livelihood.
Methods: What were the main research methods you used?
We used the coordinates (UTM) of Eastern Sarus Crane encountering during April, 2011 to June, 2013 of 522 positions and summarize data to 2 factors of 10 indicators that affect to habitat selection of the cranes from literature review and ground survey. All indicators converted into raster format and statistically analysis using the multivariate analysis, multiple regression analysis and Pearson’s correlation coefficient by SPSS+ program. Evaluate the habitat suitable with the Habitat Suitability Index (HSI) in combination with the Potential Surface Analysis (PSA) and had result inform of Ri and Si. The total value of Ri multiplying with Si in all indicators are determining HSI value and has value ranging from 0 (non-suitable) to 1(suitable) for classified to 3 classes of low, moderate and high. Data Presented inform of habitat suitability map of Eastern Sarus Crane and suggestions to wetland management for conservation.
Results: What are your most important results?
Eastern Sarus Crane selected habitat is a continuous and large area, lower elevation, nearest the water bodies that had water depth do not exceed to 35 cm, cover in natural and agricultural wetland, far away from the road, communities and low density of household. The suitability ranking shows most study area (54.51%) were classified in moderate level, high level (40.12%) and low level (5.37%), respectively at the 90% confidence level.
Discussion: What are your important discussion points and what is the relevance of your results to conservation (if any)?
Results demonstrate a suitability habitat of Eastern Sarus Crane in the nature decline when has human activities factor are involved. Lesson learn from of this study can improve the ecological factor effecting Eastern Sarus Crane habitat and improved decision-making for prediction and conservation management planning of natural wetlands for support survival and the population of Eastern Sarus Crane to release back in the future.[/et_pb_text][/et_pb_column][et_pb_column type=”1_3″ _builder_version=”3.12.2″ parallax=”off” parallax_method=”on”][/et_pb_column][/et_pb_row][/et_pb_section][et_pb_section fb_built=”1″ admin_label=”Subscribe” _builder_version=”3.12.2″ background_color=”#000000″ use_background_color_gradient=”on” background_color_gradient_start=”#D883F8″ background_color_gradient_end=”#352DBE” background_color_gradient_direction=”96deg” background_color_gradient_start_position=”29%” background_image=”http://188.8.131.52/~sccs/public_html/wp-content/uploads/2018/09/dots-2.png” custom_margin=”|||” custom_padding=”0||0||true|false” saved_tabs=”all” global_module=”309″][/et_pb_section]]]>
