Land cover classifications and associated data from treatment areas enrolled in the Phragmites Adaptive Management Framework, 2018 During 2018, uncrewed aerial vehicles (UAVs or 'drones') were used to collect spatially referenced aerial imagery from 20 management units (sites) enrolled in the Phragmites Adaptive Management Framework, a collective learning program developed by the Great Lakes Phragmites Collaborative. Management units were located in Michigan, Ohio, and Wisconsin (USA). Invasive Phragmites australis (hereafter "Phragmites") had been managed at each management units some time previously by the landowner or land manager, and aerial imagery was then collected to create cover classifications distinguishing live and dead Phragmites from the surrounding landscape using object-based image analysis with training based on ground-truth...

To aid in Phragmites management and future studies, we used RNA-seq data from multiple types of plant tissue to construct forty-nine P. australis transcriptomes via different assembly tools and multiple parameter settings, resulting in seven assembled transcriptomes for further comprehensive assessments. The optimal transcriptome (“cd-hit”) was selected for functional annotation and downstream analyses. This data release contains the seven assembled transcriptomes, and data derived from the optimal transcriptome (functional annotations, tissue-specific...

Leaf and bract cells of more than 30 species in 18 families of seed plants were surveyed for the presence of intracellular bacteria and several experiments were designed to find and analyze nutrient exchanges between bacteria and plant cells. This dataset contains the results of 1) histochemical analyses to detect hormones, superoxide, and nitrogenous chemicals around bacteria within plant leaf and bract cells, 2) experiments to assess the differential absorption of isotopic nitrogen into plants, and 3) genetic analysis of bacteria isolated from plant material.

Wetland vegetation community data were collected by quadrat sampling in 1995, 2002, and 2010 and topographic data were collected via GPS and LIDAR positional data in 2010.

H. Wigg) and curly dock (Rumex crispus L.)). The experiments included the following assessments of Phragmites-associated bacteria (Pseudomonas spp, strains Sandy LB4 (Pseudomonas fluorescens) and West 9 (Pseudomonas sp.)): capacity for plant growth promotion (using Poa annua seeds), Poa annua and Phragmites australis seed germination and...
