Dexham Marsh & Upland Prairie
This is a rare habitat complex of upland blackland prairie and progressing downslope to a
bottomland hardwood forest adjacent to a cattail marsh near Dexham Road.
Location: north or Route 66 (Lakeview Pky) on Dexham Road and located on the north side of Norma Dorsey Elementary
School in western edge of Rowlett. Directions: Park at the NORMA DORSEY ELEMENTARY (K-5): 6200 Dexham Road off
of Highway 66 in Rowlett. To the northwest you will see the large cattail marsh and associated willows. If you walk up the hill
behind the school's chain link fence you will see the large remnant prairiewith an existing trail used by school children and cyclists.
If anyone has any information on the place please submit it to us.
We "discovered" this area a couple of years ago during a Christmas Count and have found birds here that are hard to find
elsewhere in the Metroplex. The habitats include about 25 acres of cattail marsh with mature Black Willow progressing upslope
through green ash and other saplings to a 75- acre upland tallgrass prairie with Little Bluestem, Dropseed, prairie forbs, and
rare hillside seeps characterized by spikerush (Eleocharis sp), Foxtail (Setaria sp.), Bushy Bluestem (Andropogon glomeratus).
The larger seeps are eroded and characterized by Eastern Red Cedar. The extensive cattail marsh can be found by continuing
east on 66 a short ways and turning left onto Dexham Road. The cattails are next to Norma Dorsey Elementary
School. Unfortunately I’m not sure if the marsh is private property, and there is no good access, but it’s a great spot for
Swamp Sparrows, blackbirds, and Common Yellowthroats, and I've found Virginia Rail and Sora in the cattails.
Birds include:
Common Yellowthroat White-Crowned Sparrow Red-tailed Hawk
Marsh Wren Song Sparrow
Bluejay Swamp Sparrow
Red-Winged Blackbird Field Sparrow
Cowbird Fox Sparrow
Rusty Blackbird Lincoln's Sparrow
Common Grackle LeConte's Sparrow
Starling
There aren't many places where you can see a swamp sparrow and a Leconte's sparrow within a few hundred yards
of each other. We also found a Texas Garter Snake in the prairie on Feb. 15, 2003. The area should be preserved, but we
don't know who owns it.
Update: (This update is note endorsed by the Society and is a note by the webmaster):
June, 2005. The City of Rowlett approved construction of the project, only reducing the number of homes from 128 to 100. This decision
by City Hall will spell disaster for Dexham Marsh and Prairie. School board members gave up this property in order to add more than money
to the their property-tax base. With no forethought they passed up a unique chance to education themselves and their children on
environmental values right next door.....a sad decision indeed. Destruction is slated for this fall so if you have any interest in seeing
one of our last remnant prairies in the area, go visit the
Dexham site.
The City of Rowlett approved a zoning change on April 12, 2005 from single residential estate to planned development
single residential for this pristine habitat. Plans are to construct a 130-home subdivision called LakeHill beginning in September
of 2005 along with over 8300 feet of concrete trails throughout the complex. Plans also include possibly blasting of an existing
beaver dam and trapping beavers as well as converting the wetland to a nonwetland stormwater detention pond or a "park".
In winter, thousands of blackbirds, mostly Red-wings, swarm in at sunset to roost in the nearby cattail marsh along Dexham Road.

- Ventured over to the Dexham Road cattail marsh to look and listen for rails, with no luck. However passerine migrants were quite conspicuous,with plenty of Nashville Warblers (15), Common Yellowthroats (5), and Indigo Buntings (10) flushing out of the ragweed thickets. Present in lesser
numbers were Yellow Warbler, House Wren, Empidonax sp., and Northern Flicker. In the adjacent prairie we flushed the first sparrow migrants of
the season (2 birds), but both were quite secretive and remain unidentified. And coincidentally we found a second Green Treefrog in addition to the first
one on 9/28. Both were in similar marsh habitat.
