Book Review: 'QGIS for Ecologists - An Introduction to Mapping for Ecological Surveys'

'QGIS for Ecologists An Introduction to Mapping for Ecological Surveys'

By Stephanie Kim Miles     

How does one review a guidebook to mapping software? Well, the short answer is it’s not easy.

This, coming from someone who studied similar books on software, computer networking, etc., for close to 15 years (in the past).


To begin with, I focused my attention on how concise, easily readable, useful, and how easy it was to retain the information. As well as how easy it was to put into practical practice, when actually working with the software.

Let’s start with a General Description of the book:

If you're an ecologist, wildlife researcher, or environmental consultant looking to master the art of mapping for your ecological projects, this book is your essential guide. Aimed specifically at beginners, it offers a hands-on approach to using QGIS—an accessible, open-source GIS platform—for creating the maps you need for effective reporting.

It covers the fundamental stages of map-making, providing clear, jargon-free instructions that will help you confidently create a variety of maps commonly used in ecological work. Whether you're navigating the world of ecological consultancy or conducting field surveys, this guide ensures that you have all the tools necessary to produce professional-grade maps without the steep learning curve often associated with GIS software.

Throughout, you'll gain practical skills in creating key maps such as:

  • Basic survey maps
  • Aerial imagery survey maps
  • Designated sites maps
  • Desk-study maps
  • Protected species maps
  • Habitats maps

In addition to map creation, the book walks you through essential QGIS functions, including downloading third-party datasets, creating your own data, geo-referencing images, and importing GPX files. Links to downloadable data and resources are provided, making it easy to access everything you need to replicate the processes outlined in the book. The included workflows offer step-by-step guidance that you can adapt for your own projects, ensuring that the book remains a valuable resource long after you've completed the exercises.

Whether you're a student new to QGIS or a seasoned professional looking to refresh your GIS skills, this book is the perfect companion for anyone working in ecological consultancy, conservation, or related fields. Its straightforward approach and practical applications make it an indispensable tool for anyone looking to integrate GIS mapping into their ecological work.

A volume covering everything you need to know to get started working with QGIS.

 


There are several books on QGIS currently available, as well as guidebooks to using and mastering the QGIS software.

I’ve looked into the other currently available books on QGIS. So that I can effectively inform the reader, as to how this one compares.

The other books, currently available on Amazon (for example) amount to exactly 12 separate titles, when you search for “QGIS book” on Amazon.

I’ve looked into each of them. Out of those 12, QGIS by Stephanie Kim Miles ranks right at the top of the list.



“QGIS for Ecologists” provides a hands-on guide for leveraging QGIS in ecological research and site mapping, blending clarity with technical rigor in its instructional design. The book stands out for its methodical walkthroughs, as evidenced by the included screenshots, which effectively demystify GIS workflows for both new and experienced users.

Practical Step-by-Step Instructions

Instructions are presented in actionable steps, such as grid creation, exporting data, and working with designated sites maps. Each segment carefully outlines not only what you need to do, but also why it’s important, fostering greater understanding for users unfamiliar with GIS terminology. The designated sites map section provides multiple methods—downloading basemaps, connecting to online basemaps, and adding boundary data through Web Map Services—ensuring flexibility no matter the available data or user expertise.

Focused Exercises and Guided Questions

In addition to practical tutorials, the book incorporates guided exercises reflective of an educational text. For example, users are prompted to list steps for exporting a basic map or downloading basemaps, reinforcing learning through application and repetition. These questions encourage active engagement rather than passive reading, ideal for both classroom and self-guided study.

A particular strength is the explanation of categorized symbology, a common challenge for ecologists who need to visualize complex survey data. Through the provided screenshots, the reader is taught how to add new fields, simplify attribute tables, and assign survey categories with customizable colors and symbols. The instructions are precise and result-oriented, making the process approachable for users who may not have strong technical backgrounds.

Throughout the examples, the language remains clear and professional, showing sensitivity to the likely mixed audience of scientists, students, and conservation workers. Options for data sources, connection protocols, and map coordinate systems are thoughtfully explained, covering both UK and regional needs.

“QGIS for Ecologists” is a well-organized manual that succeeds in making GIS tools accessible and relevant to ecological practitioners. The balanced use of screenshots, stepwise detail, and reflective questions helps bridge the gap between theory and practice, leaving readers empowered to create professional ecological maps and conduct spatial analysis independently.

Until next time,
Happy bat detecting! map making!

A Brand-New Bat Detector Is Coming Soon

A new and highly capable bat recorder is on the way, and it represents an exciting development for bat researchers and ecologists alike.

Details are still under wraps, but I can share that the device is a professional-grade system engineered to deliver exceptional audio quality right out of the box. It is a fully standalone, static recording unit designed for extended, unattended operation in the field—ideal for long-term ecological monitoring projects.

From what I’ve seen so far, the build quality and capabilities are impressive. I expect this new recorder will be very well received by ecologists around the world once it’s officially unveiled.

While I can’t share more just yet, I’m looking forward to providing updates as soon as information becomes available.

In the meantime, I’ll also be posting the long-delayed book reviews over the next few weeks—thank you for your patience.

Wishing everyone a successful bat call and data analysis season.

Happy bat detecting!
