The influence of host tree morphology and stem size on epiphyte biomass distribution in host trees was
assessed in Lusenga Plains National Park, Zambia for the period 2004 to 2007. A total of 8 ha were
sampled in bush land, woodland and riparian forest vegetation communities. Epiphytes were collected,
dried and weighed to obtain biomass, which was apportioned between different host tree species,
vertical and horizontal branches, crown and trunk, and small, medium, and large stems, as well as
smooth and rough bole textured substrates. Horizontal branches had more epiphytes, 50% than vertical
branches (17%). Tree canopies had more epiphyte biomass, 68% than trunks (32%). In riparian forests
Usnea articulata and Ramalina reticulata were not selective. In Miombo woodlands, epiphytes and
certain tree species with larger stems and rough bore texture were selected. Larger substrates dbh >
100 cm had higher epiphyte biomass (94.46%) followed by medium dbh 51 to 100 cm (5.29%) and the
least was on small girth dbh ≥ 20 to 50 cm (0.25%). Rough substrates had 89% biomass and only 11%
occurred on smooth bole substrates. It was concluded that tree crowns, horizontal stems and
branches, large and rough bole textured tree substrates provided suitable habitat for epiphyte seed
settling, germination and moisture retention, while exposure to sunlight supported germination and
growth of epiphytes. Maintenance of mature Miombo woodlands was therefore found to be critical in
maintaining epiphytes, while protection of preferred tree species would ensure their long-term survival
and sustenance of hydrologic functions |
