each day during trap inspection. Traps were inspected every morning during sampling
time from around 7.00am to around 11.00am since traplines were far spaced; all
specimens found in the traps were identified and recorded. Specimens not identified
immediately were collected for later identification. The traps were also used to collect
certain reptile species (see section 3.3.2.4) and amphibians (see section 3.3.2.5). Bats
were sampled using mist netting and opportunistically. Mistnetting was done early
evening and at dawn at three selected sites of Machopeni, Makangare Bwawani and
Kwa Josh Trail. Collected specimens were preserved in 70% alcohol, 10% formalin.
Specimens found alive during trap inspection and which could be readily identified
were released near the place they were captured.
3.3.2.3 Birds
Mist netting meter-net-hours (12m x 4m x hours) was conducted in three different
habitats of Machopeni, Makangare bwawani and Chokaani. The capture success was
very poor hence most bird records reported here come from direct observation (bird
watching) of birds in different parts of the forest both in daytime and and night. The
checklist also includes previously reported species occurring in Ngezi and Pemba
Island as a whole.
3.3.2.4 Reptiles
Opportunistic sampling and pitfalls (see section 3.3.2.2 above) were used to obtain
information of reptile species available in Ngezi. All sightings of the reptiles were
recorded to give clues of their occurrence and distribution in the area.
3.3.2.5 Amphibians
Most amphibian specimens were collected using bucket pitfall traps (see section
3.3.2.2 above). However for tree frogs and other amphibian groups, which are not
easily trapped in buckets opportunistic sampling was used, and those were collected
whenever they were encountered. Vocalisation especially at night was also used to
establish presence of some of the species and also detrmine their relative abundance.
Photographs of some specimens were taken for identification.
3.3.2.6 Fish
Fish specimens from artisan fishermen were identified on sight using identification
keys and knowledge of the local fishermen. Useful information on fish and fisheries
resources and exploitation were obtained from office records in Wete. Some
fishermen were interviewed and provided valuable information on fish, fishing gear,
fish spawning areas and fish marketing.
3.3.2.7 Invertebrates
Sampling of invertebrates (Butterflies, Moths, Dragonflies and Damselflies) was
carried at six transects (hereafter T1, T2, T3, T4, T5 and T6 see table above).
Collection methods used included the following:
(i) Sweeping using a sweep-net (for Odonata and Lepidoptera) was carried
out for one hour during late morning hours
(ii) A baited Butterfly trap (“banana trap”) was set in the morning and emptied
in the late afternoon or evening
(iii) An 11W fluorescent tube light trap was run for one hour during the night
to catch moths.
