| Title: | Forest monitoring data of 45 plots across the Japanese archipelago during 1980–2021 |
| Identifier: | ERDP-2024-03.1.2 |
| Abstract: |
Long-term monitoring of forest tree communities is a basis for elucidating forest structure and dynamics and for evaluating ecosystem functions such as primary production. Because global climate change is changing forest ecosystems from the local to the global scale, it is essential to document long-term monitoring data of forests to examine the temporal and geographical trends of forest changes. We report monitoring data of 45 forest plots (average area 0.69 ha; range 0.0325–6.25 ha) at 27 sites in Japan. These plots are situated within 32.38°N to 43.36°N and at elevations ranging from 8 to 2453 m above sea level. The forest plots include both oldgrowth and secondary forests, and cover various forest biomes, such as warm-temperate evergreen forests, temperate deciduous broadleaved forests, and boreal or sub-alpine coniferous forests. In each plot, all living trees and lianas larger than a certain minimum size (typically 15 cm stem girth at breast height) were repeatedly measured and survival and recruitment of stems were recorded over 5 to 40 years (average 17.3 years). The data are presented in the format used by the Monitoring Sites 1000 Project in Japan (Ishihara et al. 2011) and in the sample-based Darwin Core format. This dataset expands existing open monitoring data for Japanese forests and thereby facilitates further meta-analysis of forest community structures and changes in relation to climate change and other drivers. The complete data set for this abstract is available in electronic format in MetaCat in JaLTER at http://db.cger.nies.go.jp/JaLTER/metacat/metacat/ERDP-2024-03.1/jalter-en.

Study site and plot design
The 45 forest plots (coded as PL01–PL45) are distributed throughout the Japanese archipelago (Fig. 1). Plot latitude ranges from 32.38°N to 43.36°N, and longitude ranges from 131.17°E to 144.66°E. Elevation ranges from 8 to 2453 m above sea level (Fig. 2). Monitoring periods range from 5 to 40 years, with an average of 17.3 years. The total monitoring period covers 1980 to 2021 (Fig. 3). In all 45 plots, 269 censuses were performed. Plot size ranges from 0.0325 ha (PL41) to 6.25 ha (PL18), with an average of 0.69 ha. Most plots are rectangular, but one plot (PL06) has an irregular shape and another plot (PL21) includes non-monitored areas within its rectangular outline. All plots were established in natural forests without introduced trees and experienced no large natural or anthropogenic disturbances (e.g., logging) during monitoring. Some plots have experienced insect damage (mainly oak wilt disease spread by a bark beetle), deer browsing, or windstorm damage during their monitoring periods. The plots can be categorized into two forest age classes: old-growth forest which has persisted at least 150 years without large disturbances before monitoring (28 plots at 18 sites) and secondary forest established within 150 years before monitoring (17 plots at 11 sites). The information sources of these recent disturbance are variable, including personal observations, historical documents, inferences from tree ring analysis, and their combinations.

Field methods
Trees were measured according to the protocol of the Monitoring Site 1000 project (Ishihara et al. 2011). All living trees and lianas larger than a certain minimum size were repeatedly measured mainly with a tape measure. For some plots, calipers were used to measure small stems. The minimum size (in girth at breast height [GBH] or tree height) differs among the plots, but all stems ≥15.7 cm in GBH (5 cm in DBH) were measured except in one plot (≥31.4 cm in GBH, 10 cm in DBH; PL18). Survival and recruitment of stems were also recorded in each census. Plots were censused 2 to 23 times, with an average of 6.0. Census interval are 3.68 years on average, ranging from 1 to 23 years.

Taxonomy and systematics
All plants were identified to species level by experts. Scientific names follow the YList (Yonekura and Kajita 2003) and were checked against the GBIF Backbone Taxonomy (GBIF Secretariat 2021).
