Rogers Island

NYFA Field Trip to Rogers Island

Date: 28 September 2002

Place:  Rogers Island, Hudson River

Trip Summary (submitted by Stephen M. Young):

Fourteen hardy souls braved the wind and tides to explore the uplands, swamps and marshes of Rogers Island. The island is located in the Hudson River in southern Columbia County underneath the eastern side of the Rip VanWinkle Bridge. The day started out a little confusing as our meeting directions were not quite correct but everyone managed to make it to the island in time for the trip. After a frontal passage the night before chilly winds were gusting out of the northwest which made the canoeing portion of the trip quite a challenge. Fortunately the sunny skies and anticipation of seeing new plants kept everyone in a good mood. We piled into our canoes and kayaks and paddled north on Hollenbeck Creek to the marshes on the north side of the island. The exotic invasive Nymphoides peltata was in full bloom on the mud flats and made quite an impression. Most of the participants landed their craft on the north shore and explored the island on foot from there. After crashing through a Phragmites stand we explored a portion of the tidal swamp then headed east as the weather warmed to an open sandy upland area where we added many new species to the island's list. From there we returned to the intertidal mud flats of the west shore as the tide began to recede and identified some of the small plants that are unique to this habitat. Especially abundant were Sagittaria subulata, Elodea nuttallii and Sagittaria graminea. A few people continued in their canoes and explored the extensive marshes on the northwest side. While they were looking for a stand of golden club, Orontium aquaticum , the group exploring the shoreline on foot found a couple of large plants on the border of the mud flats. The leaves of Orontium are very distinctive but unfortunately the plants were not in bloom. From the western shoreline we turned east and traversed the island through a beautiful tidal swamp where we were able to find the state-rare swamp lousewort, Pedicularis lanceolata. We broke out of the swamp on the eastern shore of the island along Hollenbeck Creek when the tide was at its lowest. The group was able to enjoy the extensive mud flats and tidal marsh along this section where we debated the identification of the extensive stand of Acorus. After a group picture in the mud we all headed north to retrieve our canoes and drag them across the mud flats where we had paddled at high tide earlier in the day. After we cleaned off the mud, removed the sand spurs and mounted our canoes we said our farewells. It was an interesting and fun field trip that logged a total of 144 species, 90 of them previously undocumented. Thanks go to all those who participated and increased our knowledge of this important site.
