REGEN: The Northeastern Forest Regeneration Data Network
Project Goal
To help the region better understand the patterns and trends in forest regeneration, the Forest Ecosystem Monitoring Cooperative (FEMC) created REGEN: The Northeastern Forest Regeneration Data Network , an online data and methodology portal that allows users to explore, search, filter, and compare projects and datasets related to forest regeneration.
Overview
The success and patterns of tree regeneration are critical in understanding the current condition and future composition of forests in the northeastern US. In order to successfully manage forests to support forest sector viability, wildlife habitat conservation, and other important ecosystem functions, continuously monitoring and assessing regeneration is necessary.
While many monitoring efforts and research studies have collected regeneration data, this information has not been aggregated, standardized or made public to the broad group of stakeholders who could benefit from the information. The FEMC responded to these concerns by creating REGEN, a structured framework and portal which allows for discovery and comparison of projects and datasets appropriate for use when asking pertinent questions about the status and nature of the region’s regeneration data.
The data collection available through the portal includes projects and datasets ranging from long term research studies examining the effects of silviculture treatments on regeneration to those looking at the effects of natural disturbances on regeneration.
This work reflects the efforts of a broad collaborative group allowing us to work together to promote easier data discovery and utilization without duplication.

About
Detailed metadata is provided for each project, such as the size of the plots, the definition of a seedling, and what species nomenclature was used. Projects can be filtered by metadata as well as by analysis suitability, selecting only those projects that would be suitable for a particular analysis, such as analysis of sapling mortality over time.
For analysis suitability, projects were assessed on whether they had sufficient information to perform the following seedling or sapling analyses, based on the required data needed for that analysis:
| Analysis | Required data |
|---|---|
| Density | Species, count, plot size |
| Species Composition | Tallies by species |
| Mortality | Status (i.e. live and dead stems) or tracking of individual trees over time |
| Biomass | Diameter, Height |
| Browse Impacts | Browse assessments |
| Change over time | Data collected over two or more timesteps |
| Effects of treatment or management | Data per treatment or management |
| Relationship with overstory trees | Overstory tree data collected in the same locations as regeneration data |
We rated each project's suitability for analysis for that characteristic as Suitable, Partially suitable, or Not suitable:
Each project was also assessed for its compatibility with USDA Forest Service’s Forest Inventory and Analysis (FIA) program and was ranked with an FIA similarity of High, Medium or Low:
- H
- M
- L

REGEN compare Tool
The REGEN Compare Tool was designed to provide a quick visualization of how various regeneration data sets compare in their methodology and utility for addressing different aspects of forest regeneration, survivorship and health. This tool can be used to drill down into specific metadata for various data products, as well as to filter to identify datasets of interest.
To get started, browse the suitability of projects for the seedling or sapling analyses listed or use the Filter button to filter the projects by characteristics of interest such as location (state), time frame, elevation or inclusion of specific metrics such as browse or overstory crown condition.
For full details on using the compare tool, view the "How to Use" menu item at the top of the tool.
