The National Conservation Easement Database (NCED) is an initiative of the U.S. Endowment for Forestry and Communities. Additional financial support has been provided by the Peter and Carmen Lucia Buck Foundation; the Geraldine R. Dodge Foundation; the Gaylord and Dorothy Donnelley Foundation; the Knobloch Family Foundation; the Graham Foundation; the USDA Forest Service, State and Private Forestry; the U.S. Fish and Wildlife Service, Landscape Conservation Cooperative; and the U.S. Geological Survey. The NCED team also collaborates with the USGS National Gap Analysis Program (GAP) Protected Areas Database – United States (PAD-US) on data acquisition and standards.

NCED Completeness Maps

DISCLAIMER: The following completeness maps are only estimates of completeness. While we have done our best to provide an accurate estimate, we know that some of the estimates are our "best guesses" based on the data we have currently collected. We will be continuing to work on generating better estimates in the future.

METHODS: The coverage maps of NCED completeness measure the number of easements that are in the NCED database compared to the ESTIMATED total number of easements the NCED team is aware of from the Land Trust Alliance Census data and the NCED data collection efforts. Easements are known, yet not in NCED because, 1) they have not been digitized, 2) they were withheld from NCED, or 3) the NCED team is still working with the easement holders to collect the information.

Two separate completeness reports were developed based on publicly-held easements and NGO-held easements in 2014. The NGO report relies on data from a National Land Trust Census, produced by the  Land Trust Alliance in 2010, which lists all of the easements held by the Land Trust community. Approximately 70% of known land trusts are included in the Census. There is no census for publicly-held easements so the total number of publicly-held easements is based on the data collection efforts of NCED.

We are currently applying for funding to improve our baseline numbers for public easements, and will be working with the Land Trust Alliance in 2016 as they re-do their National Land Trust census. These efforts will allow us to better estimate completeness in the future.

These maps are to be used as a general guide for database completeness and will change (both increase and potentially decrease) as we move forward with the NCED project.

This dataset was last updated in October 2016. The Updates Table shows what has been added and changed since June 2014. The Completeness Maps below provide estimates of how complete the NCED data are for each state.
