Although the potential impacts of threats, whether real or perceived, was the primary cause of concern (i.e., that mentioned by the largest percentage of participants) for only 14 of the 65 species examined, threats were of at least some concern for 62 (95%) of them (Table 3). What is the exact nature of these threats? The primary threats are, in decreasing order:
a. Habitat loss 52 species
b. Human disturbance 9 species¹
c. Other(unspecified)threats 6 species²
d. Contaminants 2 species³
If we again assume that this sample is representative of all listed species, expert opinion suggests that habitat loss is a threat to the overwhelming majority (80%) of the species of concern, followed by human disturbance (14%), other (unspecified) threats (9%), and contaminants (3%).
