62:		Title:	Black Crowned Night-Herons of the Lake Calumet Region, Chicago, Illinois
		Volume/Number:	37 2005 3-4 August
		Issuing Agency:
		Description:	Irregularly published technical series. This volume consists of two issues: 37 3 , entitled "Nesting Ecology of Black-crowned Night-Herons at Lake Calumet Wetlands" and 37 4 , entitled "Population Trends in a Black-crowned Night-Heron Colony at Lake Calumet Wetlands" Volume 37 3 Partial Abstract: We examined the nesting ecology of a Blackcrowned Night-Heron Nycticorax nycticorax colony located at wetlands associated with Lake Calumet in south Cook County, Illinois,during the 2002 and 2003 nesting seasons. This area of southeastern Chicago has been greatly impacted by heavy industry, solid and chemical waste disposal, urbanization, and altered hydrology. Volume 37 4 Abstract: The number of active Black-crowned Night-Heron Nycticorax nycticorax nesting colonies in Illinois has declined significantly over the past century. Habitat loss/degradation and other factors such as exposure to environmental contaminants and competition for nest sites at established colonies may have contributed to this decline. In this study, we examined recent trends in population levels of Black-crowned Night-Herons nesting at wetlands associated with Lake Calumet in southeastern Chicago, Illinois. The number of Black-crowned Night-Herons nesting annually at these wetlands has fluctuated widely over the last two decades. Immigration of herons from riverine colonies may have driven population increases during the mid-1980s and early 1990s. However, this population has remained relatively stable at between 300 and 400 pairs during 19972003.

66:		Title:	Vascular Flora of Middle Fork Woods Nature Preserve, Vermilion County, Illinois
		Volume/Number:	38 2008 4 June
		Issuing Agency:
		Description:	Irregularly published technical series. Abstract: The vascular flora of Middle Fork Woods Nature Preserve, Vermilion County, Illinois, was studied during the growing seasons of 19992002. A total of 376 species were found: 12 ferns, fern-allies, and gymnosperms; 99 monocots; and 265 dicots. The three families with the largest number of species were the Poaceae (44), Asteraceae (39), and Cyperaceae (34, 29 of which were members of the genus Carex). The overstory and woody understory of six forest communities were surveyed: a mature second growth dry-mesic upland forest dominated by Quercus alba (white oak) and Q. velutina (black oak); an old growth, dry-mesic savanna dominated by Q. alba with a dense understory of Acer saccharum (sugar maple); SW-facing and NE-facing forested slopes of a mesic ravine, both dominated by A. saccharum and Q. alba; a southern flatwood forest/ephemeral pond community dominated by Q. bicolor (swamp white oak); and an immature second growth dry-mesic upland forest dominated by Q. alba and Carya ovata (shagbark hickory). Ground layer plants were surveyed in spring and fall in the dry-mesic upland forest communities, and for each species the relative cover, relative frequency, and importance values were determined. The preserve, comprised mostly of oak-hickory forest communities, was found to be in relatively good ecological condition. Mature and maturing second-growth oaks were present throughout much of the preserve. Sugar maples dominated the understory and, along with the dense overstory, were apparently limiting oak regeneration. The non-natives Lonicera spp. (bush honeysuckles), Elaeagnus umbellata (autumn olive), Alliaria petiolata (garlic mustard), and the native sugar maple, will continue to need to be controlled. Prescribed fire is recommended to limit populations of these species.
