Their incredible resistance to environmental stress <a href=\"https:\/\/doi.org\/10.1016\/j.cub.2011.04.032\" target=\"_blank\" rel=\"noopener\">such as drought<\/a> and <a href=\"https:\/\/doi.org\/10.1016\/S1011-1344(01)00269-X\" target=\"_blank\" rel=\"noopener\">UV radiation<\/a> was also crucial to their ability to evolve on land. <\/p>\n\n<p>One of the most critical features of land mosses is their <a href=\"https:\/\/doi.org\/10.1023\/A:1026598724487\" target=\"_blank\" rel=\"noopener\">desiccation tolerance<\/a>, which is the ability to survive near-complete drying out. When water is scarce, mosses can enter a state of suspended animation where they greatly reduce their metabolic activity, allowing them to survive until conditions improve. Some species, such the desert moss <em>Syntrichia caninervis<\/em>, can survive a hundred years in this dormant state and revive within hours of rewetting. <\/p>\n\n<figure class=\"align-right zoomable\">\n            <a href=\"https:\/\/images.theconversation.com\/files\/528030\/original\/file-20230524-17-q4xy6y.JPG?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip\" target=\"_blank\" rel=\"noopener\"><img  decoding=\"async\"  alt=\"\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAAlwSFlzAAAOxAAADsQBlSsOGwAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  class=\" pk-lazyload\"  data-pk-sizes=\"auto\"  data-ls-sizes=\"(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px\"  data-pk-src=\"https:\/\/images.theconversation.com\/files\/528030\/original\/file-20230524-17-q4xy6y.JPG?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip\"  data-pk-srcset=\"https:\/\/images.theconversation.com\/files\/528030\/original\/file-20230524-17-q4xy6y.JPG?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=337&amp;fit=crop&amp;dpr=1 600w, https:\/\/images.theconversation.com\/files\/528030\/original\/file-20230524-17-q4xy6y.JPG?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=337&amp;fit=crop&amp;dpr=2 1200w, https:\/\/images.theconversation.com\/files\/528030\/original\/file-20230524-17-q4xy6y.JPG?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=337&amp;fit=crop&amp;dpr=3 1800w, https:\/\/images.theconversation.com\/files\/528030\/original\/file-20230524-17-q4xy6y.JPG?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=423&amp;fit=crop&amp;dpr=1 754w, https:\/\/images.theconversation.com\/files\/528030\/original\/file-20230524-17-q4xy6y.JPG?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=423&amp;fit=crop&amp;dpr=2 1508w, https:\/\/images.theconversation.com\/files\/528030\/original\/file-20230524-17-q4xy6y.JPG?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=423&amp;fit=crop&amp;dpr=3 2262w\" ><\/a>\n            <figcaption>\n              <span class=\"caption\">Canary thread moss is widespread in Britain.<\/span>\n              <span class=\"attribution\"><span class=\"source\">Silvia Pressel<\/span>, <span class=\"license\">Author provided<\/span><\/span>\n            <\/figcaption>\n          <\/figure>\n\n<p>Studying the mechanisms of this ability in modern plants helps scientists understand how <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S1369526617301887\" target=\"_blank\" rel=\"noopener\">ancient plants might have adapted to land<\/a>. It is possible that studying desiccation tolerance in mosses could help scientists  discover new ways to protect crops from extreme drought in the future.<\/p>\n\n<p>These little plants are also entwined with human history. From exploiting the antiseptic properties of <a href=\"https:\/\/doi.org\/10.1016\/j.jep.2017.07.025\" target=\"_blank\" rel=\"noopener\">moss for wound healing<\/a> to using broom moss (<em>Dicranium scoparium<\/em>) for <a href=\"https:\/\/doi.org\/10.1007\/978-3-030-97415-2_2-1\" target=\"_blank\" rel=\"noopener\">relief of constipation<\/a>, mosses have played a substantial role in relieving human suffering.<\/p>\n\n<p>So, perhaps we should think twice before raking out mosses from the lawn.
