Fine-Root Ecology Database (FRED) Version 2.0
Authors:

Description of data set:
To address the need for a centralized root trait database, we compiled the Fine-Root Ecology Database (FRED) from published and unpublished data sources. We have continued to add to the FRED database since the release of FRED 1.0, and a new version of FRED is now available. FRED 2.0 houses 50% more data, with more than 105,000 observations of root traits; ancillary data on associated site, vegetation, edaphic, and climatic conditions from across the globe have also increased concurrently.
FRED is focused on fine roots (roots less than 2 mm in diameter), as coarse roots are studied using different methodology, often at very different scales, and have different traits and trait interpretations. However, FRED accepts data collected from roots of all sizes, and already contains several observations of coarse roots. Data collection will continue for the foreseeable future.
More details about FRED and the motivation for undertaking this monumental data compilation can be found in:

Summary:
The Fine-Root Ecology Database (FRED) is a global data set of plant root traits and associated ancillary data on site, vegetation, edaphic, and climatic conditions.
