The Pinetum was first planted in 1767 by the Baker family who owned the Bayfordbury Estate and now holds a magnificent collection of conifers. With around 200 species (about one third of all conifer species in the world), Pinetum provides examples of nearly every possible feature important for conifers identification. This makes it a popular destination for wildlife walks.
The site is maintained by the Friends of Clinton-Baker Pinetum since 1994 with regular work parties. See their website for more information and how to join.
Below is a figure from a short article on identification of conifers with spirally arranged needles published in British Naturalists’ Association’s journal Country-Side following a BNA Herts Branch meeting in January 2020. More information about conifer identification here.
