Abstract
A study was conducted to survey trees of
ethnobotanical importance in the
University of Ibadan Campus, Nigeria.
Total enumeration of trees with diameter
≥10cm at breast height (DBH) was done.
DBH and total height of the trees were
measured while GPS was used to record
the location of the trees to map their
distribution. Nearest neighbour analysis
was used to determine the spatial
distribution pattern of the trees. Tree
identification was done by a taxonomist
while the medicinal values of the plants
were acquired through oral interview of
indigenous respondents and herbal
practitioners within and outside the
University community and ethnobotanists.
Results showed that there was a
total of 54 species belonging to 25
families. Mangifera indica was the most
(21.60%) recorded while Terminalia
superba had the highest mean tree height
of 29.8 m. The largest mean DBH (133.3
cm) was observed in Adansonia digitata.
The spatial distribution pattern of trees of
ethnobotanical importance was clustered
(Z=-26.25; p<0.05). The study reveals
that leaves and barks were the parts of the
plants that are mostly used to cure
ailments. The study recommended that the
trees should be domesticated.
