Key messages

  • One study evaluated the effects of training tourist guides to minimize disturbance and promote marine and freshwater mammal conservation. The study was in the Kenai Fjords (Alaska).

COMMUNITY RESPONSE (0 STUDIES)

POPULATION RESPONSE (0 STUDIES)

BEHAVIOUR (1 STUDY)

  • Behaviour change (1 study): One before-and-after study in the Kenai Fjords found that fewer harbour seals were disturbed during kayak excursions after training was provided to kayak guides.

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A before-and-after study in 2002–2011 at a glacial lake in the Kenai Fjords, Alaska (Hoover-Miller et al. 2013) reported that after training was provided to kayak guides, fewer harbour seals Phoca vitulina were disturbed in the presence of kayaks than before training. Results are not based on assessments of statistical significance. Numbers of seal disturbances (seals moving from the ice into the water) each year during kayak excursions were lower after training was provided to guides (total 0–9 disturbances; 0–0.02 disturbances/hour) than before (total 0–30 disturbances; 0–0.05 disturbances/hour). Training was provided to tourist guides in 2006 to operate kayaks more carefully around seals (details reported in Jezierski 2009). Voluntary guidelines for viewing marine mammals from vessels were introduced in 2000, and multiple outreach activities took place in 2002–2011 (public presentations, workshops etc.). Remote-controlled video cameras recorded seal disturbances during kayak excursions in May–September 2002–2011. Observations were made during 81–92 days in each of four years before training (2002–2005) and during 70–92 days in each of six years after training (2006–2011).
