Abstract:
... Although critical to evaluating success, monitoring is often neglected in ecological restoration. An important question is how much area should be sampled to adequately monitor restoration projects, particularly as projects become larger. We elucidate this issue by testing the following hypotheses: There is an optimal sampling area (OSA) that efficiently captures variation in the estimation of eco ...

Abstract:
... When conducting a forest inventory, sometimes portions of plots cannot be measured due to inaccessibility. Two primary methods have been presented to account for partial nonresponse in the estimation phase: (i) use a ratio-to-size estimator or (ii) apply an adjustment factor to all plot observations in proportion to the missing area. Both approaches provide identical estimates of the population me ...

Abstract:
... KEY MESSAGE: Using satellite-based maps, Ceccherini et al. (Nature 583:72-77, 2020) report abruptly increasing harvested area estimates in several EU countries beginning in 2015. Using more than 120,000 National Forest Inventory observations to analyze the satellite-based map, we show that it is not harvested area but the map’s ability to detect harvested areas that abruptly increases after 2015 i ...

Abstract:
... Silicon (Si) pools and fluxes are affected by plant community shifts in forest ecosystems. Moso bamboo (Phyllostachys pubescens) is a Si accumulating plant, and its expansion exerts various ecological effects in colonized forest ecosystems. However, it is unclear how bamboo expansion might alter the biogeochemical Si cycle. To estimate the consequences of bamboo expansion on Si availability and bi ...

Abstract:
... What are typical values and dynamic status of live‐tree biomass pools in old‐growth, mesic, cool temperate forests? A handful of biomass density estimates in eastern North American temperate forests show large biomass/carbon reserves on a per‐area basis. However, it is less clear whether these ecosystems are, over multi‐decade scales, typically steady‐state or non‐equilibrial carbon pools. Previou ...

However, if only the forest stand, which does not include the land where the forest stand is located, can be used as collateral for a loan with a low interest rate, then a new chapter of forestry history has been born. Low interest rate loans with forest stands as collateral have been adopted in Indonesia as a new scheme of provid ...

Abstract:
... Soil carbon (C) stocks are known to increase as a consequence of the forest succession of a pioneer pine forest (PF) to a pine and broad-leaved mixed forest (PBMF), and then to a monsoon evergreen broadleaf forest (MEBF). However, the underlying mechanisms of soil C stock accumulation along the succession of these subtropical forests remain unknown. Here, we tested the hypothesis that the accumula ...
