Nakusp, BC End of Year 2016 Matsutake Forecast Chart

Fair to good year in Naksup area. The formation ending on 10-3, combined with the first formation, should have produced in a wide area of pickers patches. It is unclear if the last chance for formation beginning on 10-12 was successful. Growth was likely slow near end of season and then faster with last chance of formation on 10-12.

Matsutake Forecast 2016

Matsutake forecasts will begin August 1, 2016.

Thanks to those who participated last year.

Forecasts are available to Registered Members Only. To receive forecast, you must ask on the board or email Email request is preferred. Those who participated last year will automatically receive forecasts this year.

You may ask for a forecast for 1 area only from those listed under the title Matsutake Forecast list on every page. The purpose for these forecasts is science and to provide some insight into possibilities of production of Matsutake, pine mushrooms, in their favorite picking area, not to provide a overview across the entire region.

Those who receive forecast are required to report accuracy of forecast.Reports are not due until you find mushrooms , in forecast or not. Reports are due, after a flush is forecast, finding mushrooms or not. Reports are used to adjust forecast, derived from chart, to increase accuracy. Forecasts are updated every 5 to 7 days, If you do not report when a report is indicated, you will be suspended from receiving further charts that year. Reports are not shared with the public or others participating and receiving forecasts.

These reports help determine at what temperature soils are cool enough for formation to begin and when soils are too cool to form mushrooms in an area. Forecasts are based on temperatures down loaded from each area. Each forecast location indicates what general temperatures in the area and not specific temperatures in areas where matsutake grow. A temperature of 60 degree in one area may indicate formation is possible, where as in another area it may be 55 degree.

Rise in temperature is also important to determine volume of crop formed. Too little rise will not form mushrooms. Too much rise will cause forming mushrooms to burn and die or not allow mushrooms to form. Generally a 3 to 9 degree rise is needed. 5 to 8 degree rise is generally ideal.

Length of formation period determines volume of crop formed. Generally a 4 to 5 day period is needed to form commercial quantities. The longer the formation period, with proper temperature rise, the larger the crop. A 14 to 20 day period, with ideal temperature rise, will produce an excellent crop.

Flushes are initiated with a cooling near or below the low which initiated the formation period.

Failure of a formation does not mean no mushroom that year. Formation is possible until soils are too cool to allow mushroom to form.

Naksup Area Matsutake Forecast Charts 2015

Below are the forecast charts for Matsutake fruiting in 2015 near Nuksup. I’ve posted them so those who picked the area last year can see how they worked for the patches each picker picked.

Those who received them last year determined they were accurate for the patches they picked last year. This may not be true in all the patches of pickers who picked there. Forecasts are for the entire area and may not be accurate for individual patches.

To receive forecast this year, read the message below this one.

Successful picking this year to all.
