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
