is an important wild edible mycorrhizal mushroom in Japan. The domestic matsutake harvest has been declining for 80 y. Nagano Prefecture, a central region of Japan, is the area that has been most productive of matsutake during the past 20 y. To study how matsutake harvesting was affected by forest management, an experimental site was established in a pine forest in Nagano Prefecture in 1980. Two plots were established: a managed plot (MP) in which all trees except pine were cut, pine trees were thinned, and soil litter layer was removed; and a control plot (CP) with no forest management. The numbers of matsutake fruiting bodies were recorded annually in both plots for 41 y. The annual matsutake harvest was stable in the MP but decreased in the CP, while the number of shiro increased in the MP and was stable at the low level in the CP. These trends were suggested to be affected significantly by the thicker humus layer and large root biomass other than pines in the CP. This is the longest record of matsutake harvest in the managed forest, which reveals the importance of such long-term forest management for the sustainable matsutake harvesting.
是日本一种重要的野生可食用菌根蘑菇。国内松茸产量在过去80年一直在下降。日本中部地区的长野县是过去20年里松茸产量最高的地区。为了研究森林管理对松茸采收的影响，1980年在长野县的一片松林中设立了一个实验场地。设立了两个样地：一个是经营样地（MP），除松树外所有树木被砍伐，松树被间伐，土壤枯枝落叶层被清除；另一个是对照样地（CP），未进行森林管理。41年间每年记录两个样地松茸子实体的数量。MP样地的年度松茸产量稳定，而CP样地的产量下降，同时MP样地的菌塘数量增加，CP样地则稳定在低水平。这些趋势被认为受到CP样地中除松树外更厚的腐殖质层和大量根系生物量的显著影响。这是经营林中松茸采收时间最长的记录，揭示了这种长期森林管理对松茸可持续采收的重要性。
