The Prairie Naturalist
On a clay-loam mixed grassland dominated by honey mesquite (Prosopis glandulosa Torr.) in northern Texas, we quantified soil pH, soil organic carbon (OC), electrical conductivity (EC), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sodium (Na), zinc (Zn), iron (Fe), manganese (Mn) and copper (Cu) in response to various effects of summer and winter fire treatments from 1991–1996. We conducted summer fire between August and September, and winter fire between January and March. Treatments that included summer fires increased soil pH, EC, Na, and Cu and temporarily decreased soil OC and Mn (P ≤ 0.05). The winter fire treatment …

Baptisia arachnifera (Hairy Rattleweed) is an endangered herbaceous legume that only occurs in Wayne and Brantley Counties of Georgia, United States. Many of the remaining populations exist in areas now managed for timber. This study investigated the effects of Imazapyr, an herbicide commonly used in timber management, on health and vitality of B. arachnifera under both field and greenhouse conditions. This study also analyzed leaf and soil samples from six populations of B. arachnifera to determine the nutrient content of the leaves. A recensus of a B. arachnifera population was also conducted in a site without commercial timber management. In …
