The aspiration of EMR is to help bridge the gap between science and practice; and the feature articles that are (uniquely for any journal) published in each issue of EMR play an important role in that aspiration. It is no surprise then, that the mechanisms we decided to use to celebrate the journal’s 20 years of publication was to compile a virtual issue that republishes over 20 feature articles representing some of the most outstanding ecological management and restoration case studies carried out in the Australasian region over the last two decades.

The features republished in the virtual issue (launched in November 2019) cover a very diverse range of subjects and geographic areas and are contributed by authors including researchers, practitioners and landholders. But what makes this virtual issue particularly special is that, for the first time in EMR’s history, we have commissioned updates from the authors of each feature. These updates are now all published on the EMR project summaries website and accessible through the virtual issue link or directly through http://www.emrprojectsummaries.org. The significance of this is quite profound as it allows all of us to see what has transpired at the sites since the ‘snapshot’ provided in the original publication, which is anywhere between 5 and 20 years depending on the original date of publication of the feature. In effect, the publications themselves provide a ‘then’ and ‘now’ perspective that mimics other such ‘before and after’ mechanisms that are commonly used by us in monitoring changes over time.

The theme of monitoring over time has been much‐visited by EMR over the decades, and the current issue is no exception. Most pertinent to the theme is this issue’s interview with David Lindenmayer, leader of multiple long‐term, large‐scale monitoring projects. David describes how well‐framed monitoring design and well‐targeted subject matter can lead to rich sources of long‐term data to inform improved management of biodiversity. Checking long‐term historical information is also very important to sharpen our plans for restoring degraded sites. This is illustrated in this issue’s feature by wetland restoration practitioner, Mark Bachmann, who demonstrates how using historical materials can help us correctly identify targets for management and restoration.

A long‐term view is also apparent behind this issue's comment piece by Carla Catterall. Carla points out the importance of retaining weeds in the landscape during the long‐term transition from cleared agricultural land to the commencement of recovery of rainforest at a landscape scale. Not only do weeds in some areas provide resources and habitat for fauna (also see Cross and colleagues’ comment piece this issue) but also the fauna, particularly frugivorous birds, play an invaluable role in driving the distribution of many rainforest species. Through this approach, many grazed landscapes of 50 years ago are now well on the way to recovery to secondary rainforest.

A long‐term view is also important when considering the success of investments in revegetation in Australia, a topic reviewed in this issue by Stuart Collard and colleagues. The review highlights the potential mismatch between funding and the true costs of revegetation and shows that lessons from examination of past failures and successes need to be learned as quickly as possible to improve current and future programmes. This process of learning from long‐term efforts is also emphasized in this issue’s assessment of revegetation techniques by Joe Greet and colleagues, and the report on long‐term results in bauxite mine restoration in south west Australia by Tai White‐Toney and colleagues.

As EMR enters a new decade, EMR looks forward to a continued stream of submissions of outstanding management‐relevant research reports and case studies. To this end, we ask readers to consider EMR as a publication outlet for your project report, whether research reports or practitioner case studies. In particular, however, we can now ask readers to spread the word about the EMR project summaries web page. This platform is proving invaluable not only as a streamlined publication outlet for practitioner case studies and research project abstracts but also as a highly valued mechanism for any EMR authors to communicate updates of their work published in EMR over its now 20‐year history.

EMR的愿望是帮助弥合科学与实践之间的鸿沟；在每一期《电子病历》中发表的专题文章（对于任何期刊而言都是唯一的）在这一愿望中起着重要作用。因此，我们决定用来庆祝该杂志成立20周年的机制不足为奇，这是一个虚拟的问题，它重新出版了20篇专题文章，这些文章代表了澳大利亚进行的一些最杰出的生态管理和恢复案例研究在过去的二十年间

虚拟版（于2019年11月发布）中重新发布的功能涵盖了非常广泛的主题和地理区域，并且由包括研究人员，从业人员和土地所有者在内的作者提供。但是使这个虚拟问题特别特别的是，这是EMR历史上的第一次，我们委托了每个功能的作者进行更新。这些更新现在都发布在EMR项目摘要网站上，可以通过虚拟问题链接或直接通过http://www.emrprojectsummaries.org进行访问。这样做的意义非常深远，因为它使我们所有人都可以看到自原始出版物中提供的“快照”以来现场发生了什么，视快照的发行日期而定，该快照可能需要5到20年的时间。有效，

几十年来，EMR一直关注随时间进行监视的主题，当前问题也不例外。与主题最相关的是本期对多个长期，大型监控项目负责人David Lindenmayer的采访。David描述了精心设计的监测设计和目标明确的主题如何导致丰富的长期数据来源，从而为改进的生物多样性管理提供信息。检查长期历史信息对于提高我们的恢复退化站点的计划也非常重要。湿地恢复从业者马克·巴赫曼（Mark Ba​​chmann）在本期专刊中对此作了说明，他演示了如何使用历史资料来帮助我们正确地确定管理和恢复的目标。

卡拉·卡特尔（Carla Catterall）在本期发表的评论文章背后也有着长期的看法。Carla指出了在从开垦的农业用地到景观规模的雨林恢复的长期过渡中，将杂草保留在景观中的重要性。杂草不仅在某些地区为动物群提供了资源和栖息地（另见Cross和同事的评论，本期），而且动物群（尤其是食肉类鸟类）在推动许多雨林物种的分布方面也发挥着不可估量的作用。通过这种方法，许多50年前的放牧景观现在都可以恢复到二级雨林。

在考虑在澳大利亚的植被恢复投资是否成功时，长远观点也很重要，这是Stuart Collard及其同事在本期中讨论的主题。审查强调了资金与植被再造的实际成本之间潜在的不匹配，并表明需要尽快学习过去失败和成功的经验教训，以改进当前和未来的计划。乔·格里特（Joe Greet）及其同事在本期对植被恢复技术的评估中以及泰·怀特·托尼（Tai White-Toney）及其同事关于澳大利亚西南部铝土矿恢复的长期结果的报告中也强调了从长期努力中学习的过程。

随着EMR进入新的十年，EMR期待继续提交优秀的与管理相关的研究报告和案例研究。为此，我们要求读者将EMR视为您的项目报告（无论是研究报告还是从业人员案例研究）的出版物。但是，尤其是，我们现在可以要求读者宣传有关EMR项目摘要网页的信息。事实证明，该平台不仅可作为从业人员案例研究和研究项目摘要的精简出版物，而且对于任何EMR作者而言，都具有很高的价值，可以交流其在EMR已有20年历史中发表的最新作品的宝贵机制。
