Since the beginning of the study, 36 million trees have been lost, which is equivalent to 175,000 acres of tree cover. The loss is being attributed to development for the accommodation of larger urban populations, dam - age from insects such as the emerald ash borer, and natural aging. The biggest losses were in Rhode Island, Georgia, Alabama, Nebraska and Washington D.C. Only three states had small gains, Mississippi, Montana and New Mexico, but the amounts were considered "non significant." One solution, tree plant - ing programs, have seen mixed results as many of them have reportedly failed to reach their stated goals. The Bee Informed Partnership, a collaboration group consisting of experts from around the country, in conjunction with a variety of research institutes, recently completed its 12th annual survey of managed bee colony loss experienced in the United States and its territories. The results found that during the winter months (1 October, 2017 – 1 April, 2018) approximately 30.7% of managed colonies in the U.S. were lost: an increase of 9.5% over the previous year. But respondents reported a lower colony loss during the summer than in the 2016/2017 sur - vey - 17.1% as opposed to18.2%. One notable trend highlighted by the survey is that the self-reported "level of acceptable winter colony loss" has increased to almost 21%, the highest it has ever been, indicating that beekeepers now expect higher rates of colony termination.
