Welcome to TCD Botany

Welcome to the Botany Department of Trinity College Dublin, a leading centre of teaching and research in plant sciences. Our interests range over the areas of plant systematics, plant community ecology, and environment and sustainability.

We study plants because they are of vital importance; as the source of all our food, the oxygen we breathe and most of the medicines we use. They are central to the processes of global climate change and to the provision of food and energy for an expanding human population. In the face of such change their conservation is increasingly vital.

Prof Jennifer McElwain
Head of Botany

The TCD Botanical Society is working to increase an interest in botany and promote environmental awareness among society members and the student population in an interesting and informative way.We are actively pursuing this by organising lectures, talks, discussions, walks, film showings, field trips and other events that are of a botanical nature.
