Raleigh Swamp Recovers from a Swamping

Raleigh Swamp is a prominent, even dramatic feature of the Raleigh Greenway at the intersection of Crabtree Boulevard and Raleigh Boulevard, joining Buckeye Trail to Middle Crabtree Trail and crossing a large shallow body of water with a causeway. The water was never intended to be permanent, but a wetland was turned into a shallow lake by the work of beavers, as explained in this 2013 post.

The place is a paradise for visiting birds, thirsty deer and other wildlife, and an amazing collection of turtles that bask by the piled up dozens on the many logs protruding from the water. The causeway was built with best ecological practices, minimizing disruption, but it has needed repairs recently because of extensive flooding. Cara and I visited in November 2018 and saw some of the work.

The crossing of the greenway with a utility cut has been strengthened and guarded with metal gates. The northwestern end of the site has a short stretch of asphalt that has repeatedly been ruined as the flooded marsh cuts through the shoulder of Crabtree and dumps excess water into the creek. looks like they are going to repair (instead of culvert) it once again, but this spot has closed the causeway, officially that is, for months. Most people just make their way around the mild barricades.

Different species of trees can tolerate shorter or longer periods of flooding. Ash, river birch and of course willows can survive many weeks of inundation. But if flooding lasts too long, trees die and the vegetative regime changes.

This area was a scrubby wetland with a smattering of drier tussocks and paths through it until the construction of the Raleigh Boulevard bridge. Many relics of the former trees dot the wide expanse of water. There is thus a small justiofication for the term used by locals and myself, Raleigh Swamp, though in fact this is a marsh. Whatever you call it, it’s a great place to bike walk, fish, or bird watch.

Below is the illustration I created from the lead photograph for my new book, the Natural History of Raleigh. Raleigh Swamp is featured in Chapter Four.  Happy trails!

  1. When is your book coming out ? Would love to read it. I read a book by Scott Huler and was fascinated by the detail Scott presents.
