Methods

[Setting of the study area] - About to install the line transect of about 1km~3km on a mountain trail. Basically vegetation control Street in the vicinity of the point of? that include a variety of vegetation types from the wind??vegetation to Yukita vegetation It is desirable ? For the line transect determine the route that is suitable for investigation in each mountain range every year as much as possible to continue the investigation in its route.[Survey timing and frequency]: And research is conducted every year once or twice a year July bumblebee worker (worker bees) appears through mid-August than late carried out during the good weather. Survey period priority for each site adjust the time to fit within the possible target investigation period determined by each site (one of tone ??period generally fit in within a period of about 2 weeks). When bad weather even within the target study period and not performed when windy carried out to set the preliminary date investigation. It should be noted that the weather during the survey there was a sudden change when it becomes inappropriate situation to survey fill in the situation in the questionnaire to stop the investigation.[Survey methods]: - Select the entire length 1km~3km about the line transect reconnaissance once in one direction at a constant speed and to record the species of plants that had been kind and flower-visiting of bumblebee who witnessed. Record when is easy-to-understand point is recorded by dividing the route (section) if any. The root of the division (section) is fixed and does not vary for each survey. ? In the first survey for the root of the line transect the starting point end point and separated of investigation superceding point (start and end points of the section) is recorded by GPS. And surveys at the beginning and at the end (Moshiku for each start and end points) of the section is a case to put a once -separated to study in each section Yellow the weather (cloud cover) to record. Cloud cover is overlooking the whole sky to record in increments of 10% in the range of 0 to 100 percent. The number of individuals recorded in each of the - flower-visiting the plant species.As regards bumblebee species identification and recording at least Bumblebee (foreign Species) or to describe how other species. If you cannot visually check capture with butterfly net release after confirmation the Exiled. If you cannot identify to the species referred to in the following manner. Bumblebee other bumblebee ? non-western Bumblebee whether also unknown ? Unknown. ? If possible set forth caste of bumblebee (queen worker male) also.[Systems and the amount of work study] - Once the investigation per 1-2 people. Tone that can to some extent of the bumblebee and the identification of the plant with the naked eye auditors need.[Data obtained]: - Bumblebee such type and number of individuals as well as plant species list we are using - Which is a specific foreign organisms western presence or absence of a giant bumblebee invasion [Necessary equipment etc.] ? GPS (mandatory for the first time) ? If necessary binoculars butterfly net bumblebee Handbook etc.? Unit of abundance = IndCountInt, Unit of biomass = NA
