Greetings,
Since our last release, the NCED team has collected data on new publicly and privately held conservation easements from state aggregators and data providers across the United States. In addition, we continue to clean and edit existing data to improve its accuracy and usability.
Our team can work with you to edit or improve your data for NCED. We can help collect easement shapefiles, or will work to digitize from paper maps. This year we worked with Avalonia Land Conservancy in Connecticut to re-project their spatial data, adding 17 of their easements (594 acres total) to NCED during the 2016 update.
Visit the NCED
website
to search, review, and download the latest updates to the database.
As always, please
stay in touch
to let us know how you are using NCED in your work.
Sincerely,
The NCED Team

PAD-US 1.4 Available Now
NCED and Protected Areas Database of the United States (PAD-US) Data Managers teamed up to ensure non-sensitive easements are represented in PAD-US 1.4, which was published by USGS in May (
view the announcement).
New web mapping services make PAD-US easier to interpret, and several layers highlight the significant contribution of conservation easements to the nation.

NCED Use Case: National Geographic, May 2016
National Geographic's May 2016 Special Issue is devoted entirely to Yellowstone, America's first National Park. The NCED layer helped inform land ownership in a map of the Greater Yellowstone Ecosystem titled Who Owns This Land?, which highlights the challenges that conservation managers face due to conflicting interests and unsustainable development.

Public Agency Easement Holder Survey Update
In our continuing effort to understand the size and scope of conservation easements in America and the completeness of NCED, our team conducted an email survey of public agencies at the local, state, and federal level who hold conservation easements. The survey went out in February, 2016, and results were accepted through the end of May.
We received over 200 responses and are now using the information received to update our NCED completeness estimates for publicly held easements.
Many thanks to those of you who completed the survey!!

Upcoming Academic Easement Survey
Researchers at the University of Wisconsin-Madison will soon be conducting a survey about the NCED. The survey asks for respondents' perspectives on the benefits and challenges associated with NCED, and responses are confidential.
Some of you may receive a survey, so keep an eye on your inbox this Fall.
