Course: Broadleaf and Conifer Trees: Winter Identification and Ecology - HAU

This 2.5 day intermediate course explores conifers and broadleaved trees in winter in the UK.

As autumn turns to winter, the broad-leaved trees lose their colour and the conifers stand out in contrast. This course will focus on teaching the practical skills of identification for conifers and broad-leaved trees in winter. We will also look at the differences in ecology and biology of the different types of trees.

This course includes:

• Comparison of broadleaf and conifer ecology and biology
• Diagnostic features for field identification of broadleaf trees in winter
• Diagnostic features for field identification of conifers
• Experience of identification in the field with an expert tutor

From the start of 2027, when you purchase this course, a free copy of our Tree in Winter AIDGAP will be posted to you. If you already have a copy, why not share it with family, friends, or colleagues.

For broad-leaved trees in winter, you can no longer rely on the leaf shape and fruits for identification – bare twigs and winter buds help identify different species. However, in contrast, conifers are easier to identify because the majority of them retain their foliage throughout the winter and all their cones are fully formed.

In this course, you will learn about the biology and ecology of trees. You will use different keys for identification, look at the key features of the different families and genera of conifers and broadleaf trees. You will study specimens of different cones, foliage, twigs and bark and practise looking for appropriate characteristics to confirm species identification.

Additionally, it will cover the techniques for collecting and preserving voucher specimens, alongside ethical and legal considerations for scarce species and specimens (such as veteran trees). The course will also introduce tree pests and diseases.

By the end of the course, you will be able to:

• Critically examine and synthesise the structural, physiological, and ecological complexities of broadleaf and conifer trees, highlighting their evolutionary significance, adaptation strategies, and contributions to ecosystem services.
• Demonstrate skills in identifying common UK broadleaf and conifer trees during winter, using diagnostic features such as bark, twigs, buds, and cones.
• Apply skills in the collection, preservation, and validation of voucher specimens.
