- Association Diameter at breast height was a useful estimator of crown structural complexity.
- Observation Epiphytes averaged 27.1 kg per tree.
- Observation Alectorioid lichens dominated epiphyte biomass at 19.3 kg per tree.
- Observation Other lichens had 3.3 kg per tree.
- Observation Bryophytes had 2.6 kg per tree.
- Observation Cyanolichens had 1.9 kg per tree.
- Observation The foliage region had the highest lichen biomass, 16.4 kg per tree.
- Observation Branches had 8 kg per tree of lichen biomass.
- Observation Trunks had 2.6 kg per tree of lichen biomass.
- Observation Alectorioid lichens predominated in the upper, middle and outer crown.
- Association Relative height and limb size were the most significant crown structural attributes for epiphyte distribution.
- Association Limb size strongly affected bryophyte distribution regardless of height.
- Association Height, crown length, trunk surface area and exposure, branch distribution and exposure determined epiphyte distribution and abundance.
