Important Message about LEARN NC

LEARN NC is evaluating its role in the current online education environment as it relates directly to the mission of UNC-Chapel Hill School of Education (UNC-CH SOE). We plan to look at our ability to facilitate the transmission of the best research coming out of UNC-CH SOE and other campus partners to support classroom teachers across North Carolina. We will begin by evaluating our existing faculty and student involvement with various NC public schools to determine what might be useful to share with you.

Don’t worry! The lesson plans, articles, and textbooks you use and love aren’t going away. They are simply being moved into the new LEARN NC Digital Archive. While we are moving away from a focus on publishing, we know it’s important that educators have access to these kinds of resources. These resources will be preserved on our website for the foreseeable future. That said, we’re directing our resources into our newest efforts, so we won’t be adding to the archive or updating its contents. This means that as the North Carolina Standard Course of Study changes in the future, we won’t be re-aligning resources. Our full-text and tag searches should make it possible for you to find exactly what you need, regardless of standards alignment.

How Vegetation Affects the Growth and Migration of Run Hill Dune

The northeast winds are generally stronger than those from the southwest, causing the Run Hill Dune to migrate overall to the southwest. Though sea oats, sea grapes, and American beach grass growing on the dune tend to slow its migration, there is simply not enough vegetation to keep Run Hill Dune in place.

Figure 4 shows vegetation growing in the shadow of northeasterly winds, acting to trap sand and slow the igration of the Run Hill Dune.
