Yes, trees are a big help, according to many organizations, including Food and trees for Africa, we need more trees to fight climate change.
There are many studies showing through the process of photosynthesis, trees pull the gas out of the air to help grow tree leaves, branches and roots.
But according to the Mt climate portal, trees can’t absorb enough CO2 to stop climate change on their own, no matter how many we plant.
Moreover, a drying climate in the Savanna biome, for example, could change to undesirable exotic forests in the coming years, if we do not watch what trees are planted, where, and when.
Fire and herbivores are useful tools to manage the biome, to stimulate fresh growth.
But as the climate gets drier, burning will be suppressed, leading to a transforming from grasses to forests.
“The tipping point is where there is insufficient grassy fuel to support the fire, leading to a regime shift from savannah to forest” according to South African ecologist, Professor William Bond.
African savanna has vegetation rich enough to support mammals such as elephants, zebras, giraffes, lions and cheetahs.
Endemic plants include Rhodes grass, red oats grass, star grass, lemon grass, and some shrubs.
