24 June 2016 Botany Bill JournalPlant ProfileSites around refuge

Today, I forayed on the South Tract and spotted a bunch of Bald Cypress trees thriving in a swampy area next to Reddington Lake.  Bald Cypress is not native this far north, but can do all right when planted in the right place.  In this case, they were planted by Fran Uhler back in the […]

Although this seepage swamp, which is located in the northwest part of the North Tract along Sweet Gum Lane, is only a short distance from the road, it is not clearly visible unless you are carefully looking for it. It is named for the abundance of Clethra alnifolia L. (Sweet Pepperbush) found here. During my […]

29 May 2015 Botany Bill JournalSites around refuge

Today while visiting the Pitch Pine Wetlands, I spotted my first ever Six-spotted Fishing Spider (Scientific name: Dolomedes triton Walckenaer). She did not seem to be bothered by my poking around. I think she was just patiently waiting for something to come by for her to prey on. From what I understand, this is a […]

At the corner of Sweet Gum Lane and the road that leads to the BGE powerline Right of Way, there is a small grove of mature pitch pine. One or two of them are in the running to be state champions. From what I have been able to gather, there was a small village near […]

17 April 2015 Botany Bill JournalSites around refuge

This is one of the most bizarre sights I have found on the refuge. It is tree growing around a concrete block, almost as if it is trying to swallow it. The tree had no leaves yet, but I believe it was a Southern Red Oak (Quercus falcata) based on the bark and the leaves […]
