Fernow Experimental Forest site, station Compartment 8, subcompartment A, commerical clearcut treatment in mixed hardwood forest, study of relative frequency of Acer saccharum (sugar maple) in units of percent on a yearly timescale
The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities.

Monitoring clearcutting and subsequent rapid recovery in Mediterranean coppice forests with Landsat time series
<p>This dataset considers information from clear-cut coppice forest occurred between 1999 and 2015 in three different area of Tuscany Region (Italy). </p> <p>The dataset consists in one shape file and two csv files.</p> <p>The shape file contains in 2371 spatial polygons of clear-cut occurred in the three area between 1999 and 2015. The polygons were generated using visual interpretation of the Landsat Time Series and high resolution regional ortomosaic. Photo interpreters delineated the spatial extent of each clear-cut and recorded the year of harvest, adopting a minimum mapping unit of 0.1 hectares. The database associated with shape file report information related with area extent of clear-cut, year of clear-cut and the forest types that is associated with the clear-cut derived by the Tucant Regional Forest Inventory (RFI) data that give information on dominant species. </p> <p>The .csv files reported the temporal characteristic of clear-cut based on Landsat Time Series data and based on Airborne Laser Scanner (ALS) Canopy Height Model (CHM), in order to describe the temporal trend of clear-cut based on remote sensing data.</p>
Data from: Functional response of plant communities to clearcutting: management impacts differ between forest vegetation zones
1. Understanding of the ecological impacts of logging practices on biodiversity and associated ecosystem processes is essential for developing sustainable forest management approaches. We documented the impacts of clearcutting on the functional structure of tree and herbaceous communities in hemiboreal, cool-temperate, warm-temperate and subtropical forests in the Japanese archipelago and identified forest vegetation that is vulnerable to deterioration of important ecosystem functions. 2. We combined species data for leaf, stem, flower and fruit traits related to productivity, nutrient cycling and habitat quality for wildlife with phytosociological vegetation data from unmanaged and previously-clearcut forests, then calculated functional structure indices (community mean of trait values, functional richness and functional divergence) of plant communities. 3 .For tree species, functional structure indices of specific leaf area (SLA), leaf carbon and nitrogen concentrations, maximum height, wood density and flower size differed between unmanaged and clearcut forests, while for herb species, only maximum height differed between the two forest types. 4. Functional structure indices showed divergent patterns across forest vegetation zones. In hemiboreal, cool-temperate and warm-temperate forests, the community means of SLA and leaf nitrogen concentration were greater and that of leaf carbon concentration was smaller in clearcut than in unmanaged forests. Although clearcut forests had greater species richness than unmanaged forests, functional richness and/or functional divergence of maximum height were smaller in clearcut forests. In hemiboreal and cool-temperate forests, functional richness and functional divergence of SLA were also smaller in clearcut forests. In contrast, subtropical forests showed no differences in species richness and functional structures between unmanaged and clearcut forests. 5. Synthesis and applications. Functional redundancy of plant communities differs among traits and among forest vegetation zones. After intensive logging, hemiboreal, cool-temperate and warm-temperate forests were more vulnerable to the loss of ecosystem functions related to leaf and stem traits of tree species than were subtropical forests, which appeared relatively resilient. Locally adaptive management to maintain multiple ecosystem functions should be developed based on the degree of functional complementarity among plant species in forest communities.

Clearcutting and selective logging have inconsistent effects on liana diversity and abundance but not on liana–tree interaction networks
<p class="MsoNoSpacing">Understanding the effects of forest management on lianas and their interaction with trees is an important step towards effective forest management. Our study therefore aimed at quantifying the patterns of liana diversity and abundance, and liana-tree interaction network structure in response to logging disturbance in a moist semi-deciduous forest in Ghana. We sampled lianas (diameter at 1.3 m ≥ 1 cm) and their host trees (diameter at breast height ≥ 5 cm) in 90 20 × 20 m plots among three forest management regimes: clearcut-logged, selectively-logged and old-growth forests. Liana species diversity and abundance in the selectively-logged forest was similar to that of the old-growth forest, while that in clearcut-logged forest was significantly lower than both above-mentioned forest types. Liana-tree interaction networks showed anti-nested structure, which is a form of nonrandom community organization. There were significant modularity and degree of specialization, but no significant connectance in the network structure. Largely, most of the species were peripherals, while a few species acted as structurally important species (i.e. module hubs, network hubs and connectors) in the three networks. A different set of species acted as structurally important species in the different forest management regimes. Our findings call for a re-examination of clearcutting logging in forest management in view of its negative effects on lianas, and we recommend prioritizing important modules in liana-tree network for future conservation.</p>
