Methods

[Setting of the study area] - Line transect routes and fixed-point survey of the route. The installation. Line transect route: about 2 on a mountain trail setting the km ~ 3km about. Basically vegetation survey and point route passing through the vicinity of. - Sentinel survey route: in the flower garden about 100m ~ 200m degree of short route or because it overlooks the surrounding area to set the kill fixed point.? In the line transect survey butterflies groupFrom the collection centered on the indicator species of alpine butterfly ( see below )To record the variation of the number of individuals.? In the fixed point survey as the target of the butterflies all species for the crowd also lowland species increase of attention to conduct a survey on the pressure and the like.[Survey timing and frequency]: And research time is different depending on the time (areas where both species of occurrence of spider Ma Benihikage and Benihikage overlap that but roughly between late August from late July). The survey period at each site in it fits within the target study period determined by each site as long as that can (generally within a period of about 2 weeks). ? When even goal investigation within the period bad weather as well as the investigation when strong wind is not performed the preset the??to carry out the investigation. In addition the weather suddenly changes in the survey in inappropriate situations in the survey if it becomes is fill in the situation in the questionnaire to stop the investigation. And research time is 8:00 to 14:30 and then implementation conditions of survey research at the start of the temperature 16 ? or more illuminance and more than 25000lux. - Survey conducted once every 1-3 years. However complement if necessary taking into account the regional and species characteristics perform a foot survey.[Survey methods]: In line transect survey set the full-length 2 ~ 3km about the route one at a constant speed the survey once to improve wide area to the minute as the selected species (candidate as indicator species of the butterfly who witnessed Cloth to Benihikage - spider Ma Benihikage etc.) to record the number of individuals to avoid duplication of the same individual. If possible to record the data for all species. Route there is no place in particular priority if set to pass through the vicinity of the point where doing vegetation survey. Record when was found if there is a cheap point record by dividing the route (section). Division of the root (section) every time without change every time we do a survey to fix.In the fixed-point survey constant overlooking the route or around a certain level of 100m ~ 200m in the flower garden set the point 8:00 to 14: 00 hour between between 1 times for 15 to 30 minutes round trip to either fixed point. The butterflies all species of the species name and the number of individuals was confirmed by the observation record. 1 set once the investigation in one hour and bets fixed point investigation once the investigation time 8:00 to 14: it is referred to as basic to perform 30 7 set between. If the weather changes by the seven sets of investigation it cannot be carried out of the local was scheduled to perform the questionnaire column of time and to record the effect of the bad weather missing. At that time considering the weather conditions worse 1 if possible implementation times 5 or more sets of investigation as an active (re-examination without). It cannot be visual confirmation captured in a butterfly net only species to expulsion after confirmation. (?) Unit of abundance = IndCountInt, Unit of biomass = NA
