(Pomchote, unpublished data). Therefore, the breeding site should not be disturbed by any anthropogenic activities, especially road disturbances. We strongly recommend that the road to the summit of Doi Soi Malai be opened only after the breeding site has dried up, or alternatively, the road should be accessible during the winter and dry seasons, with walking to the peak as the preferred option.

Moreover, in addition to the road disturbances mentioned earlier, both the areas surrounding and within Mae Tuen Wildlife Sanctuary have been heavily impacted by habitat alteration and deforestation, leading to forest fragmentation, primarily due to agricultural activities, especially cabbage cultivation (
