The majority of microclimate studies have been done in topographically complex landscapes to quantify and predict how near-ground temperatures vary as a function terrain properties. However, forests understory can be strongly influenced also by vegetation. We quantified the relative influence vegetation features physiography (topography moisture-related variables) on managed boreal central Sweden. used multivariate regression approach relate temperature 203 loggers over snow-free seasons an area ∼16,000 km2 remotely sensed on-site measured variables forest structure physiography. produced climate grids monthly minimum maximum at 25 m resolution using only mapped predictors. quality predictions models containing predictors (MAP models) were compared with (OS models). Our data suggest that during warm season, where landscape variability is largest, canopy cover basal most important microclimatic drivers for both temperatures, while physiographic (mainly elevation) dominated autumn early winter. MAP able reproduce findings from OS but tended underestimate high overestimate low temperatures. Including drivers, particularly soil moisture, are yet lacking form should improve maps. Because dynamic nature forests, continuous updates parameters needed accurately results management (e.g. stand size, composition) conservation may play key role amplifying or impeding effects climate-forcing factors locally modify impact global warming.

Large Trees Dominate Carbon Storage in Forests East of the Cascade Crest in the United States Pacific Northwest

Frontiers in Forests and Global Change, Journal Year: 2020, Volume and Issue: 3

Large-diameter trees store disproportionally massive amounts of carbon and are a major driver cycle dynamics in forests worldwide. In the temperate western U.S., proposed changes to Forest Plans would significantly weaken protections for large portion greater than 53 cm (21 inches) diameter (herein referred as "large-diameter trees") across 11.5 million acres (⁓4.7 ha) National lands. This study is among first report how storage forest ecosystems be affected by policy. We examined proportion large-diameter on lands east Cascade Mountains crest Oregon Washington, their contribution overall aboveground (AGC) storage, potential reduction stocks resulting from widespread harvest. analyzed inventory data collected 3,335 plots found that play role accumulated stock these forests.

High ecosystem service delivery potential of small woodlands in agricultural landscapes

Abstract Global forest loss and fragmentation have strongly increased the frequency of patches smaller than a few hectares. Little is known about biodiversity ecosystem service supply potential such small woodlands in comparison to larger forests.

Protection gaps and restoration opportunities for primary forests in Europe

Diversity and Distributions, Journal Year: 2020, Volume and Issue: 26(12), P. 1646 - 1662

Published: Sept. 15, 2020

Abstract Aims Primary forests are critical for forest biodiversity and provide key ecosystem services. In Europe, these particularly scarce it is unclear whether they sufficiently protected. Here we aim to: (a) understand extant primary representative of the range naturally occurring types, (b) identify types which host enough under strict protection to meet conservation targets (c) highlight areas where restoration needed feasible. Location Europe. Methods We combined a unique geodatabase with maps cover, potential natural vegetation, biogeographic regions protected quantify proportion across Europe's gaps in protection. Using spatial predictions locations account underreporting forests, then highlighted could complement Results found substantial bias distribution types. Of 54 assessed, six had no at all, two‐thirds less than 1% was primary. Even if generally protected, only ten more half their strictly Protecting all documented requires expanding area networks by 1,132 km 2 (19,194 when including also predicted forests). Encouragingly, large non‐primary existed inside most thus presenting opportunities. Main conclusion perilous state, as acknowledged EU's “Biodiversity Strategy 2030.” Yet, there considerable opportunities ensuring better restoring structure, composition functioning, least partially. advocate integrated policy reforms that explicitly irreplaceable nature ramp up efforts alike.
