The protection of plant resources in urban areas is a growing conservation concern. Inventory activities that document species presence and stewardship plans that protect and enhance these areas are needed. The results of a botanical inventory of the Crooked Creek Community Juan Solomon Park in Indianapolis, Indiana, are reported in this paper. The 46-acre park contains three distinct habitats, supporting a wide variety of plants. One hundred seventy-nine vascular plant species from 64 families were identified, including 53 (29.6%) non-native species that are naturalizing within the park. Despite its high percentage of alien species and urban setting, the park is …
The Royal Catchfly (Silene Regia; Caryophyllaceae) In Indiana, Rebecca W. Dolan
The Royal Catchfly (Silene Regia; Caryophyllaceae) In Indiana, Rebecca W. Dolan

Botanist Thomas Nuttall called the royal catchfly, Silene regia, "one of the most splendid species in existence." This red-flowered, hummingbird-pollinated member of the Caryophyllaceae is a perennial herb of prairies and glades. Because of the conversion of much of its former habitat to agriculture, the royal catchfly is considered threatened in Indiana. The species' historical and present-day distribution in the State, documenting the current status of all known locations, including population sizes and co-occurring species, are reported in this paper. Only 8 of the documented 23 historical locations still support the plant. No populations occur in dedicated nature preserves or …
Vegetation And Environment In An Adjacent Post Oak Flatwoods And Barrens In Indiana, Rebecca W. Dolan, Eric S. Menges
Vegetation And Environment In An Adjacent Post Oak Flatwoods And Barrens In Indiana, Rebecca W. Dolan, Eric S. Menges
Scholarship and Professional Work - LAS
To compare adjacent post oak flatwoods and barrens communities in south-western Indiana, we used vegetational, environmental and fire history data in multivariate analyses. Barrens had greater dominance by post oak and lower tree species richness, but variation in tree species composition was not strongly related to soil moisture, litter depth or other environmental gradients measured. Tree growth has been slow and variable, with little difference between the barrens and flatwoods. Barrens and flatwoods differ in herb species composition, but with considerable overlap. In the barrens, herbaceous vegetation composition was correlated with tree basal area, litter depth and soil moisture; in …
