Hollymount represents an area of well-developed, swamp carr woodland dominated by mature alder and grey willow. Reed canary-grass and the greater pond-sedge dominate the ground flora with tussock sedge also very conspicuous. Trees are encrusted with a luxuriant growth of lichens, and bracket fungi are frequent on the many dead branches and trunks.
Within the swamp woodland, fluctuating water-filled ditches represent the principal site for water violet in Northern Ireland.
An adjacent wooded drumlin exhibits a natural transition from wet alder dominated wood to a dry oak wood with a mixed ground flora of bluebell , wild garlic and ferns.
Associated semi-natural habitat within Hollymount is largely fen. Common reed and creeping bent dominate along with reed canary-grass and associated species such as yellow iris.
