Plant community data along elevational gradients in China's 17 mountains

Area of Science:

• Ecology
• Botany
• Conservation Biology

Background:

• Mountains in China are vital for biodiversity conservation, offering unique habitats.
• Limited standardized open datasets exist for plant diversity along elevational gradients in these mountains.

Purpose of the Study:

• To establish a comprehensive, standardized open dataset of plant diversity across elevational gradients in Chinese mountains.
• To provide baseline data for studying plant diversity changes and informing conservation strategies.

Main Methods:

• Collected plant diversity data from 370 permanent sampling plots across 17 mountains in China.
• Recorded species identity and abundance of woody plants (≥1 cm diameter at breast height).
• Calculated species-level basal area, abundance, and relative importance value for all plants and vegetation layers.

Main Results:

• The dataset includes 1,493 species from 121 families and 450 genera.
• It spans diverse ecosystems from tropical rainforests to tundra, covering a wide elevational range (166 to 3,835 m a.s.l.).
• The data covers a broad geographic area (46° longitude, 24° latitude).

Conclusions:

• This dataset provides crucial baseline information for understanding plant diversity patterns in mountain ecosystems.
• It enables direct comparisons across mountains to assess climate and land-use change impacts.
• Facilitates informed conservation strategies for mountain biodiversity.
