Mountain Birdwatch 2.0: 2010-2018

Mountain Birdwatch (MBW) 2.0 is a long-term citizen science monitoring program for 10 bird and 1 mammal species that breed in high-elevation spruce-fir forests of the northeastern United States and, formerly, southeastern Canada. Initiated in 2000 as Mountain Birdwatch 1.0, MBW provides the only region-wide source of population information on these high-elevation breeding birds. Each June, under the coordination of the Vermont Center for Ecostudies, volunteers perform repeated point counts at nearly 750 long-term fixed sampling sites along hiking routes in Vermont, New Hampshire, Maine, and eastern New York. Primary emphasis was placed on Bicknell’s Thrush, a montane-fir specialist that breeds only in the Northeastern U.S. and adjacent portions of Canada. In 2010, the program underwent many positive changes to reemerge as Mountain Birdwatch 2.0. All of the sampling locations prior to 2010 were permanently abandoned, and new sampling locations were chosen using a generalized random tessellation stratified (GRTS) procedure.

山地观鸟计划2.0（Mountain Birdwatch 2.0, MBW）是一项长期公民科学监测项目，聚焦栖息于美国东北部及原加拿大东南部高海拔云冷杉林的10种鸟类与1种哺乳类动物的繁殖种群。该项目于2000年以“山地观鸟计划1.0”之名启动，是该区域内唯一针对此类高海拔繁殖鸟类的全域种群信息数据源。每年6月，在佛蒙特生态研究中心（Vermont Center for Ecostudies）的协调下，志愿者在佛蒙特州、新罕布什尔州、缅因州及纽约州东部的徒步路线沿线近750个长期固定样点开展重复点计数调查。本项目的核心监测对象为比克内尔鸫（Bicknell’s Thrush）——一种仅分布于美国东北部及加拿大毗邻区域的山地冷杉林专性繁殖物种。2010年，该项目历经多项优化升级，以“山地观鸟计划2.0”全新面世。2010年之前的所有样点均被永久废弃，新样点通过广义随机镶嵌分层（generalized random tessellation stratified, GRTS）抽样法遴选产生。更多详情可访问：https://vtecostudies.org/projects/mountains/mountain-birdwatch/
