A book that is both a rhapsody and a threnody: Dave Goulson celebrates nature and laments what we’re losing of it. This is what he says in the preface:

In 2003 I bought a derelict farm deep in the heart of rural France, together with thirteen hectares of surrounding meadow. My aim was to create a wildlife sanctuary, a place where butterflies, dragonflies, voles and newts could thrive, free from the pressures of modern agriculture. In particular I was keen to create a space for my beloved bumblebees, creatures I have spent the last twenty years studying and attempting to conserve. (pg. ix)

Bumblebees were the subject of his previous book, A Sting in the Tale (2013). I haven’t read that, but if it’s half as good as this I will certainly enjoy it. Perhaps it’s better: Goulson is a biologist who can both educate and entertain. Expect the unexpected here: he writes about bumblebees and wild-flowers with the same enthusiasm as he writes about cheese and wine.

He’s also good at using the particular to illustrate the general. You’ll learn a lot about science and the scientific method here, from the “robotic beetle drum” he used to study death-watch beetles to the creation of “mathematical models” for predicting outbreaks of flies at a landfill site. Biology is full of puzzles and solving one often creates another. Not that they are always easy to solve: failure and frustration are part of science too and Goulson is happy to admit his own.

But he isn’t happy about the loss of wild habitats and the quickening pace of extinctions. Homo sapiens could also be called Homo exterminans:

New Zealand was colonised much more recently, about 1,000 years ago. As there were no mammals apart from bats, giant birds evolved there, including at least eleven species of moa, the largest of which stood 3.6 metres high, the tallest bird ever to live. They must have been terribly easy to track and kill, for carbon-dating of Maori middens suggests that all eleven species were driven to extinction within just 100 years of man’s arrival. (ch. 15, pg. 242; his emphasis)

It’s a long way from French meadows to Maori middens, as the crow flies, but similar themes apply: humans have exercised power over nature without proper thought for the consequences. Science is giving us more power all the time, but will it kill us or cure us? Dave Goulson is a scientist who increases my hope of the latter.

He also links apparently disparate parts of biology: parasites are part of both botany and entomology. Yellow rattle is a hemi-parasitic plant that exploits grasses and the bumblebees that visit it are parasitized by mites. The world is a web in more ways than one and many aspects of the web are described in this happy, hopeful and highly enjoyable book.
