Book Description
Agrarian Landscapes in Transition researches human interaction with the earth. With hundreds of acres of agricultural land going out of production every day, the introduction, spread, and abandonment of agriculture represents the most pervasive alteration of the Earth's environment for several thousand years. What happens when humans impose their spatial and temporal signatures on ecological regimes, and how does this manipulation affect the earth and nature's desire for equilibrium? Studies were conducted at six Long Term Ecological Research sites within the US, including New England, the Appalachian Mountains, Colorado, Michigan, Kansas, and Arizona. While each site has its own unique agricultural history, patterns emerge that help make sense of how our actions have affected the earth, and how the earth pushes back. The book addresses how human activities influence the spatial and temporal structures of agrarian landscapes, and how this varies over time and across biogeographic regions. It also looks at the ecological and environmental consequences of the resulting structural changes, the human responses to these changes, and how these responses drive further changes in agrarian landscapes. The time frames studied include the ecology of the earth before human interaction, pre-European human interaction during the rise and fall of agricultural land use, and finally the biological and cultural response to the abandonment of farming, due to complete abandonment or a land-use change such as urbanization.

Book Description
The largest intact remnant of the tallgrass prairie, the Flint Hills ecoregion, is currently under threat from the invasive weed sericea lespedeza (Lespedeza cuneata [Dumont] G. Don; SL). The objectives of this research were to evaluate the efficacy of late-season prescribed burning and fall herbicide application, alone and in concert, for comprehensive control of sericea lespedeza and to assess their broader treatment impacts on native plant communities. A 31-ha native tallgrass pasture with a light to moderate infestation of SL was divided into 16 subunits for this experiment. Each subunit was randomly assigned to 1 of 4 treatments: negative control, spray-only, burn-only, or burn-plus-spray. A prescribed burn was conducted on burn-only and burn-plus-spray subunits in early September 2016. Following the re-emergence of SL, spray-only and burn-plus-spray subunits received a broadcast application of metsulfuron methyl (Escort XP, DuPont, Wilmington, DE) at a rate of 70.1 g ˖ ha−1 in late September. Frequency and vigor of SL, total forage biomass, soil cover, and plant species composition were measured along permanent 100-m transects in each subunit prior to treatment application and again 12 mo later, in 2017 (i.e., 1 YAT). In 30 x 30-cm plots at 1-m intervals along each transect, the presence or absence of SL was noted. Where SL was present, crown maturity and maximum stem length of the SL plant nearest to the transect were recorded. Presence of multiple stems in plots was also recorded. Prior to treatment application, SL comprised 1 ± 2.0% of total basal cover and was not different between treatments (P = 0.38). One YAT, SL was more abundant (P ≤ 0.02) in negative control subunits than in spray-only, burn-only, or burn-plus-spray subunits, which were not different (P ≥ 0.95) from one another. Aerial frequency of SL, abundance of mature SL crowns, and incidence of plots with multiple SL stems were greatest (P ≤ 0.03) for negative controls, although not different (P ≥ 0.50) between the other 3 treatments. The change in forage biomass production 1 YAT did not differ (P = 0.16) between treatments. A tendency (P = 0.06) for a shift from litter cover to bare soil was noted when the spray-only, burn-only, and burn-plus-spray treatments were compared to the negative control. Graminoid basal cover was greater (P
