Latest On The Conservation Gateway

A well-managed and operational Conservation Gateway is in our future! Marketing, Conservation, and Science have partnered on a plan to rebuild the Gateway into the organization’s enterprise content management system (AEM), with a planned launch of a minimal viable product in late 2024. If you’re interested in learning more about the project, reach out to for more info!

​​The Lower New England - Northern Piedmont ecoregion includes portions of 12 states and the District of Columbia.  It extends from southern Maine and New Hampshire with their formerly glaciated, lower mountain and lake-studded landscape through the limestone valleys of western Massachusetts and Connecticut, Vermont, and eastern New York.  Rhode Island, eastern Massachusetts and Connecticut are distinctive in that the communities are more fire adapted including pitch pine and oak dominated forests on glacially deposited sandy till that forms a broad plain with many ponds.  The Northern Piedmont in Maryland, northern Virginia and eastern Pennsylvania was never glaciated and is characterized by broad gently-rolling hills and valleys upon which dry oak woods and remnant mesophytic forests occur on remnant sites, steep slopes and ridgelines.  For more, read or print the original report (pdf).

Ecoregional targets: plant and animal species

Methods used to assess plant and animal conservation targets include target selection, goal setting, and viability assessments (downloads as a pdf). Plants selected for the portfolio are in the plan report's species results section (pdf).

Ecoregional targets: terrestrial ecosystems and communities

Methods used to assess community conservation targets, including target selection, goal setting, and viability assessment (downloads as a pdf). Communities selected for the portfolio are in the plan report's terrestrial ecosystems and communities results section (pdf). The national vegetation classification for Lower New England is documented in Plant Communities of the Lower New England-Northern Piedmont Ecoregion, by Julie A. Lundgren, 2000.

Ecoregional targets: matrix forests:

Methods used to develop and assess matrix-forming ecosystem conservation targets. Matrix forest examples selected for the portfolio are in the plan report's matrix-forming ecosystem results section (pdf). Ecological Land Units (ELUs) are introduced in the methods chapter, but without much technical description. Since the original LNE/NP assessment, a new spatial dataset for ecological systems has been developed. Read more about ELUs in the supplementary metadata for systems30 raster data (.doc download).
Block reports are pdf documents that summarize all important descriptive and quantitative information about a matrix block. They were created for the 128 matrix blocks that formed the basis for the final portfolio selection of 95 high priority and alternate matrix blocks. Annotations have been added to the reports on those blocks that were changed in some way but still appear in the final set. A map of the spatial arrangement of blocks is shown below.

Ecoregional targets: aquatic systems:

Methods used to assess aquatic conservation targets, including target selection, goal setting, and viability assessment. Aquatic systems selected for the portfolio are in the plan report's aquatic results section (pdf). Download a slideshow of ecoregional planning for aquatic biodiversity in Lower New England, by Arlene Olivero in 2003, here (ppt, 80mb).

The five Lower New England Ecological Drainage Units (EDUs) are the Merrimack, Upper Connecticut, Middle Connecticut, Lower Connecticut, and Cape Cod. For these EDUs, the following tables have summary data and are ready to print (Microsoft Excel downloads).
  • Summary of fish and mussel distribution by HUC8 watershed (download)
  • Size 2 aquatic system biophysical setting summary (download)
  • Size 3 aquatic system biophysical setting summary (download)
These tables and more can be found in the appendices section of this page.
