The species of Taxus are more geographically than morphologically separable; and they were all treated by Pilger (1903) as subspecies of Taxus baccata. All species are poisonous; most contain the anti-cancer agent taxol; and a study of heartwood constituents of Taxus baccata, Taxus brevifolia, Taxus cuspidata and Taxus floridana found them to be chemically almost identical. However, the vast ecological amplitude displayed by the various described species (over 60° of latitude and an impressive temperature and precipitation range) suggests that they are, in a meaningful sense, true species. Detailed study of the genus (not neglecting the cultivated representatives), including extensive fieldwork, is much needed and long overdue[

].
Due to its limited range, this species is almost certainly not exploited from the wild, except perhaps as a wayside nibble of its fruit.
Clear felling of Pinus palustris forests during the 19th century along with selective logging of the slope forests in the early 1900s may have resulted in range reduction and habitat fragmentation during the 19th and 20th centuries. The most immediate threat facing Florida yew, however, is the lack of regeneration; a causal agent for this has not yet been identified. Rubbing and browsing by white tailed deer is also a problem as it may lead to the death of individual stems. As hunting within protected areas is prohibited, deer numbers within these areas increase during the hunting season (winter), resulting in increased pressure on the yew trees. The plant is classified as 'Critically Endangered' in the IUCN Red List of Threatened Species(2013)[

Known Hazards

All parts of the plant, except the flesh of the fruit (actually an aril), are potentially highly poisonous. They contain the alkaloid taxine and , if ingested, can cause nervousness, trembling, slow pulse, pupil dilation, difficult breathing, abdominal pain, vomiting, diarrhoea, weakness and convulsions - in larger doses it can be fatal, having a paralyzing affect on the heart[

All other parts of this plant, including the seed, are highly poisonous. When eating the fruit you should spit out the large seed found in the fruit's centre. Should you swallow the whole seed it will just pass straight through you without harm. If it is bitten into, however, you will notice a very bitter flavour and the seed should immediately be spat out or it could cause some problems. The fruit is a fleshy berry about 10mm in diameter and containing a single seed[
