As carbon emissions rise globally, finding ways to reduce emissions and store carbon are coming to the forefront of modern science. Forests are huge carbon stores thanks to the copious amount of photosynthesis they conduct. As climate change increases temperatures, trees become a very important tool in the fight against rising emissions. One study even described forest restoration overwhelmingly more powerful than all other proposed climate change solutions. You might think: “So let’s go and plant trees!” Unfortunately, it’s not so easy.
Mapping co-benefits for carbon storage and biodiversity to inform conservation policy and action (2019) Soto-Navarro et al., Philosophical Transactions of the Royal Society B, https://doi.org/10.1098/rstb.2019.0128
With the world under so many anthropogenic pressures simultaneously, trying to come up with management solutions for different issues can be a problem. Climate change and biodiversity are a great example. Storing carbon is a great way to reduce the effects of climate change, and increasing the range of forests worldwide is a great way to increase carbon storage. Yet the sort of forests that store carbon most efficiently are often poor at promoting biodiversity. They are largely made up of very similar trees, while forests that include brush, scrubs, and other layers often store less carbon, but house more biodiverse communities.
As such, finding areas that are prime specimens for a) storing carbon and b) biodiversity conservation are incredibly important, so that managers at every level (from park rangers right up to the Intergovernmental Panel on Climate Change) can know where interests overlap, and adjust plans accordingly.

This weekend, Australia will have a federal election. My country will vote, not on an individual leader, but on the party that will form government for the next 3-4 years. We’ve been led by the conservative Liberals (yes, the right-wing party are called the Liberals, it’s stupid) since 2013, and that time in Australia has not been kind to the environment. A tax on carbon was repealed almost as soon as it was implemented, prioritising large businesses has caused potentially irreversible damage to iconic ecosystems around the country, and a disregard for the potential impacts of climate change have been a trademark of the present government.
Bushfires like the ones that have ravaged Australia and California this year, could become the new norm for the generation that has been born in the last decade, an example of how our perception of ecological change is defined by what has happened in our lifetime (Image Credit: dm4244, CC BY-SA 4.0, Image Cropped)
It’s no secret that our world has undergone rapid changes in the last few decades. Extreme weather events are becoming almost the norm and species seem to be going extinct every minute. But as depressing as this may seem, the general doom and gloom we hear about the world on a daily basis still only represents a small percentage of the ills we’ve inflicted on our planet since we’ve been here.
