During the recent expedition to central Guadalcanal in the Solomon Islands, my job was to document the ferns and lycophytes. This was at the invitation of Marika Tuiwawa (University of South Pacific) who led the expedition’s plant team. It built on my previous experience working with ferns in Fiji, New Caledonia, Australia, and New Zealand. (As… Read more »

Valevahalo was the main camp for our recent Solomon Islands’ expedition. Sited at about 800 m above sea level, it is deep in the jungle of the northern foothills of Guadalcanal’s Mount Popomanaseu. I was there for eight nights, with two additional nights at a satellite camp at the nearby Haviha River. For background on the expedition,… Read more »
