Economic costs of biological invasions in the United Kingdom (2021) Cuthbert et al., NeoBiota, https://doi.org/10.3897/neobiota.67.59743
I write near constantly about non-native species on Ecology for the Masses, but I mainly focus on the negative impacts that many of them have on native ecosystems. Yet often if we want to really kick off initiatives to manage invasive non-native species, we need to point out the financial burden that many of them bring.
Yet obtaining a simple monetary estimate for invasive species is not easy. A few particularly notorious invasives tend to take up a lot of research focus, which mean that there are many species out there for which our cost estimates could be unreliable. Likewise, we’re likely to have a better picture of the impact of non-native species which have been established longer than ones who have just arrived, and haven’t been sufficiently studied or haven’t spread far enough to have had a measurable impact.
But non-native species aren’t slowing down in their spread anytime soon, so it’s important to figure out what the costs of invasive non-native have been and will be, as well as where there are holes in our knowledge that need to be filled. That’s what today’s study set out to do, by looking at invasive species in the United Kingdom.

Fascination with nature drives a huge chunk of tourism worldwide. The plains of Africa, the Amazon Rainforest, the Swiss Alps and their associated species are huge economic drivers for their respective countries, and they (ideally) increase people’s appreciation of nature. There are plenty of great examples of ecotourism as a pathway for both education and conservation.
Yet when an industry is driven by money first, nature second, of course there are going to be manifold examples of businesses deprioritising the natural phenomena they are associated with, often to the direct detriment of that phenomena. Think the masses of pollution now found around Mt Everest, or the damage caused by avid snorkellers on the Great Barrier Reef. I’ve had my own experience with tourist companies deliberately spreading misinformation about the reef – more on that at this link.

The farming industry has had a strange relationship with ecology over the years. They have been maligned by claims they shoot native species, suck up water greedily from nature and the people, and pollute our countryside with pesticides, all whilst producing the food many of us subsist on. So why haven’t ecologists worked with them more closely?
At the recent NØF 2019 Conference, Tanja Petersen and I sat down with Canadian ecologist Professor Andrew MacDougall, who has been working with the farming industry for the past six years to quantify their contribution to ecosystem services. We talked about the often damaging public perception of farmers, how his stereotypes were challenged by working with them, and the biggest problems the industry will face heading into the next fifty years.

I’ve been on a bit of a policy trip lately. The latest Norwegian Ecological Society conference was heavily policy based, so much so that it inspired me to get in touch and set up a meeting with local freshwater managers in a country in which I do not speak the local language. So when the CBD hosted a one-day seminar on the Intergovernmental Science-Policy Platform for Biodiversity and Ecosystem Services (mercifully usually referred to only as IPBES) rolled into town, I was right on board.

With the environmental movement having expanded so quickly over recent decades, it makes sense that many large corporations have started to incorporate sustainability and the environment into their business plans. But what are these business actions actually achieving? And who bridges the gap between the corporate world and the field of ecology?
At the recent Norwegian Ecological Society Conference, Tanja Petersen and I sat down with Doctor Prue Addison from the University of Oxford. Prue works with multinational corporations to aid them in integrating biodiversity considerations into their business operations. We asked her about the difference between business and academia, how she’s managed to transition between the two, and advice for others looking to make the same leap.

Two weeks ago, Norwegian Science Institute Artsdatabanken (ADB) announced that they would be changing the name of their invasive and alien species index. Formerly known as the Black List, the institute decided to use a name with less negative connotations, “Fremmedartslista“, loosely translated, the Alien Species list. Given this series’ focus on species from that list, it seems like an appropriate time to look at how we define the terms ‘alien’ or ‘invasive’ species.
