Kellogg Biological Station site, station Michigan Division 9, South Central Lower, study of Palmer Drought Severity Index in units of dimensionless on a monthly 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. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Kellogg Biological Station (KBS) contains Palmer Drought Severity Index measurements in dimensionless units and were aggregated to a monthly timescale.

Dynamics of Large Wood in a stream restoration in Michigan, USA 2004-2018
Large wood (LW) additions are commonly used to restore degraded streams, particularly in regenerating forests that have low LW recruitment due to past logging. While the short-term effects of LW input on stream structure and function are well studied, the long-term dynamics of added wood are less documented. We assessed the long-term movement and condition of LW added to three small (mean discharge, 28-47 L sec-1) midwestern USA streams. In 2004, 25 aspen logs (2.5 m L x 0.5 m D) were added to 100-m treatment reaches of three replicate streams in northern Michigan, USA, that contained low prior LW abundance. We monitored log movement and evaluated factors contributing to that movement over 14 years. Across all three streams, 41 of the 75 added logs moved downstream, with a mean travel distance of 4.0 m (SD, 7.0 m; n=75). However, all logs still remained within their original reaches. Most log movements occurred within the first three years following placement and were associated with high flow events. Individual log mobility was related to position in the channel; logs that were at least 70% submerged, and near horizontal in inclination, accounted for 83% of the single movements ≥0.5 m. In addition, after 14 years 32% of logs became part of aggregations and 86% displayed substantial decay. Our study suggests that restoration efforts that add LW to small, groundwater-dominated streams can pose minimal risk to downstream reaches or human structures, and may provide sustained ecological benefits to the ecosystem.
Settlement Trees, Southeastern Michigan Level 0
We provide a Level 0 record of trees for 27 townships in the southeastern area of Michigan's Lower Peninsula, south of the Detroit River transcribed from Public Land Surveys conducted by surveyors from the General Land Office of the United States in the 1800s. Posts were set every half mile in townships that were typically 6 miles by 6 miles square. Surveyors recorded details about the two closest trees to the posts and included information about the tree name (taxonomic specificity ranged by surveyor), tree diameter (inches), and distance and bearing from the post. Our records include the tree information and the location of the posts from which the tree information came from. These Level 0 tree data were aggregated to the 8km grid resolution Level 1 product (see msb-paleon.26 package). That product was then statistically smoothed using a statistical model that accounts for zero-inflated continuous data with smoothing based on generalized additive modeling techniques and approximate Bayesian uncertainty estimates for the Level 2 products estimating aboveground biomass (msb-paleon.23), density (msb-paleon.24), and basal area (msb-paleon.25). The data processing steps and associated code are available in the GitHub repository: https://github.com/PalEON-Project/PLS_products. These products are used in the manucript, Paciorek et al., 2020, Statistically-estimated tree biomass, stem, and basal area for the upper Midwestern United States at the time of Euro-American settlement (https://www.biorxiv.org/content/10.1101/856526v1).
