These are the savannas and grasslands that cover large swathes of the globe and have a grassy ground layer and variable tree cover.

These are the landscapes with lions, elephants and vast herds of wildebeest.<\/p>\n\n\n\n<p>Savannas and grasslands are home to nearly one billion people,\nmany of whom raise livestock and grow crops. Tropical grassy biomes were the\ncradle of humankind &#8211; where modern humans first evolved &#8211; and they are where\nimportant food crops such as millet and sorghum originated, which millions eat\ntoday. And, yet among the usual threats of climate change and wildlife habitat\nloss, these ecosystems face a new threat &#8211; tree planting.<\/p>\n\n\n\n<p>It might sound like a good idea, but planting trees here would be damaging. Unlike forests, ecosystems in the tropics that are dominated by grass can be degraded not only by losing trees but by gaining them too.<\/p>\n\n\n\n<p><strong>Where\nmore trees isn\u2019t the answer<\/strong><\/p>\n\n\n\n<p>Increasing\nthe tree cover in savanna and grassland can mean plant and animal species which\nprefer open, well-lit environments are pushed out.&nbsp;<a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/full\/10.1111\/j.1472-4642.2012.00882.x\" target=\"_blank\" rel=\"noreferrer noopener\">Studies from South Africa<\/a>,&nbsp;<a href=\"https:\/\/advances.sciencemag.org\/content\/3\/8\/e1701284\" target=\"_blank\" rel=\"noreferrer noopener\">Australia\nand Brazil<\/a>&nbsp;indicate that unique biodiversity is lost as tree cover\nincreases.<\/p>\n\n\n\n<p>This is because adding trees can alter how these grassy ecosystems function. More trees mean fires are less likely, but regular fire removes vegetation that shades ground-layer plants. Not only do herbivores like zebra and antelope that feed on grass have less to eat, but more trees may also increase their risk of being eaten <a rel=\"noreferrer noopener\" href=\"https:\/\/journals.plos.org\/plosone\/article?id=10.1371\/journal.pone.0149098\" target=\"_blank\">as predators have more cover<\/a>.<\/p>\n\n\n\n<p><a href=\"https:\/\/allafrica.com\/stories\/201907260717.html\">Read\nmore\u2026<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tree planting has been widely promoted as a solution to climate change because plants absorb the climate-warming gases from Earth&#8217;s atmosphere as they grow.
