Machair in Bloom - a botanical tour of the Outer Hebrides

21st - 26th July 2025

BuglossRest Harrow

This new tour is a relaxed look at the great variety of plant life that can be found in the Outer Hebrides. We concentrate each day on identifying as many of the flowering planst as we can whilst also delving into other groups such as grasses and sedges and aquatic plants. We explore the machair and moorland areas where we can compare the different plant communities. In the acidic and anaerobic peatlands the variety is limited although it does hold some specially adapted species such as sundews and butterworts amongst others. The machair by contrast holds a greater variety of species that are connected with agriculture that are abundant in the islands as herbicides are not used to control them as in many other intense systems elsewhere. July is peak flowering time for many of the machair species and swathes of clovers, Corn Marigold and Wild Carrot dominate the landscape in certain areas. We'll take a look at the widespread species as well as seaking out the more restricted ones which includes the chance of picking up Thyme Broomrape, the diminutive Bog Orchid and the rare Irish Lady's Tresses, if we're lucky.

Irish Lady's Tresses Long-headed Poppy

The machair is also home to probably the largest colony of Great Yellow Bumblebees in the UK which is linked to the extensive flower rich areas found here. The islands also support an abundance of insects and we'll take a look at some of them whilst we're in the field including the stunning Six-spot Burnet moth and the Large Heath butterfly amongst others.

We are based in Benbecula from where we'll explore North and South Uist as well as taking day trips to Harris and Barra. Although we'll spend the majority of our time looking at the plantlife we're bound to come across various birds and the odd otter whilst out and about. The ferry crossings between Uist and Barra / Harris will also provide opportunities to see a few seabirds and White-tailed Eagle.
