Biomass %N, %C, natural abundance 15N and 13C isotopic signatures for common and rare under- and overstory plants in long unburned and burned (1999) boreal forest stands, Caribou-Poker Creek and Delta Junction

This dataset contains leaf, aboveground stem, and fruit carbon and N concentration and natural abundance isotope data for new and old tissue fractions of common and rare plant species in burned and unburned black spruce forest stands. Stands were located in either Caribou-Poker Creek or Delta Junction, in either unburned areas, or in areas burned in 1999 fires. Biomass was collected between 2000 and 2001 in mid-July at peak biomass.本数据集包含火烧与未火烧黑云杉（black spruce）林分中，常见及稀有植物物种的新生与衰老组织组分的叶片、地上茎及果实的碳浓度、氮浓度与自然丰度同位素（natural abundance isotope）数据。这些林分分布于驯鹿-波克溪（Caribou-Poker Creek）或德尔塔章克申（Delta Junction）区域，且均属于未火烧区域或1999年火灾过火区域。生物量样品采集于2000年至2001年的7月中旬，该时段为植物生物量峰值期。
