CBS06 Line transects surveys of breeding birds throughout Konza Prairie

Like CPB01 and PBG051, this dataset includes records of bird species based on line transect sampling. These surveys re-initiate most of the original KNZ transects surveyed from 1981-2009 (initiated by Zimmerma), continue the two focal 300-m transects conducted from 2011-2016 by Sandercock on watersheds C3A, C3B, C3C, C1A, and 1D, (but not the peripheral segments which have been dropped), and adds two new 300-m transects to additional watersheds with the goals of (i) replicating all surveyed treatments at the watershed level, (ii) adequately sampling the grassland habitats present on Konza as of 2017, (iii) capturing transitions in bird community in response to woody encroachment and fire reversal treatments. The goals are to document and quantify long-term changes in the population sizes of breeding birds at Konza prairie by obtaining a standardized measure of annual breeding bird abundance at the site level and individual watershed or treatment level.

本数据集与CPB01、PBG051类似，均基于样线法（line transect sampling）记录鸟类物种数据。本次调查重启了1981-2009年间由Zimmerma发起的绝大多数原始KNZ样线，延续了Sandercock于2011-2016年间在C3A、C3B、C3C、C1A及1D流域开展的两条核心300米样线（但剔除了外围区段），并新增了两条适用于其他流域的300米样线，旨在达成以下目标：（1）在流域尺度上重复所有已开展的处理组调查；（2）充分采样2017年时康扎草原（Konza Prairie）现存的草原生境；（3）记录鸟类群落对木本植物入侵（woody encroachment）及火烧逆转处理的响应变化。本数据集的核心目标为：通过在样点尺度及单个流域或处理组尺度上获取标准化的年度繁殖鸟类丰度数据，记录并量化康扎草原繁殖鸟类种群规模的长期变化趋势。
