Improving the application of long‐term ecology in conservation and land management

Journal Articles & Books
Décembre, 2014

Significant effort is being made to develop more inclusive and systematic decision‐making frameworks in ecology, but these have yet to include palaeoecology. Doing so would address critical questions about long‐term ecological processes (spanning >50� years). This paper outlines the main barriers to the integration of long‐term ecological data (LTE) into management. Using two UK upland case studies, it uses a choice experiment to assess the value placed on LTE by ecological researchers, policymakers and practitioners.

Seeds of Success: A National Seed Banking Program Working to Achieve Long-Term Conservation Goals

Journal Articles & Books
Décembre, 2015
États-Unis d'Amérique

Seeds of Success (SOS) is a national native seed collection program, led by the US Department of Interior Bureau of Land Management in partnership with numerous federal agencies and nonfederal organizations. The mission of the SOS is to collect wildland native seed for long-term germplasm conservation and for use in seed research, development of native plant materials, and ecosystem restoration. Each year about 50 SOS teams are stationed across the United States to make seed collections following a single technical protocol.

Assessing impact of urban impervious surface on watershed hydrology using distributed object-oriented simulation and spatial regression

Journal Articles & Books
Décembre, 2014

In this study, we investigated the relationship between watershed characteristics and hydrology using high spatial resolution impervious surface area (ISA), hydrologic simulations and spatial regression. We selected 20 watersheds at HUC 12 level with different degrees of urbanization and performed hydrologic simulation using a distributed object-oriented rainfall and runoff simulation model. We extracted the discharge per area and ratio of runoff to base flow from simulation results and used them as indicators of hydrology pattern.

Preferences for wildlife management methods among the peri-urban public in Scotland

Journal Articles & Books
Décembre, 2011

Wildlife management remains a matter of considerable controversy amongst many stakeholders, particularly where lethal control (culling) is used. Wild deer provide perhaps one of the best examples of such a management ‘problem’, especially where they are encountered in peri-urban environments. Faced with potential controversy, decision-makers in public land management organisations need information which clearly differentiates between generally acceptable management objectives and methods, and less mainstream preferences.

Assessing impacts of Roads: Application of a Standard Assessment Protocol

Journal Articles & Books
Décembre, 2013
États-Unis d'Amérique

Adaptive management of road networks depends on timely data that accurately reflect the impacts of network impacts on ecosystem processes and associated services. In the absence of reliable data, land managers are left with little more than observations and perceptions to support adaptive management of road-associated disturbances. Roads can negatively impact the soil, hydrologic, plant, and animal processes on which virtually all ecosystem services depend.

Long‐term effects of tillage, nutrient application and crop rotation on soil organic matter quality assessed by NMR spectroscopy

Journal Articles & Books
Décembre, 2015
Norvège

Crop and land management practices affect both the quality and quantity of soil organic matter (SOM) and hence are driving forces for soil organic carbon (SOC) sequestration. The objective of this study was to assess the long‐term effects of tillage, fertilizer application and crop rotation on SOC in an agricultural area of southern Norway, where a soil fertility and crop rotation experiment was initiated in 1953 and a second experiment on tillage practices was initiated in 1983.

Testing DAYCENT Model Simulations of Corn Yields and Nitrous Oxide Emissions in Irrigated Tillage Systems in Colorado

Journal Articles & Books
Décembre, 2008
États-Unis d'Amérique

Agricultural soils are responsible for the majority of nitrous oxide (N2O) emissions in the USA. Irrigated cropping, particularly in the western USA, is an important source of N2O emissions. However, the impacts of tillage intensity and N fertilizer amount and type have not been extensively studied for irrigated systems. The DAYCENT biogeochemical model was tested using N2O, crop yield, soil N and C, and other data collected from irrigated cropping systems in northeastern Colorado during 2002 to 2006.

Land consolidation as a tool for its successful management

Conference Papers & Reports
Décembre, 2013
Lettonie

As a result of the Land Reform, property forming and land market, farm areas were often built up from a number of land plots (up to 20), sometimes with unfavourable order. With the rural development and stabilization of farm production, the role and tasks of rational territory organization are expected to increase significantly in the area. It can be forecasted that, as a result of land rent and further purchase and sell, and other transactions, many new farmland properties are expected to appear that will not correspond to the requirements of rational territorial organization.

Human behavioral impact on nitrogen flow--A case study of the rural areas of the middle and lower reaches of the Changjiang River, China

Journal Articles & Books
Décembre, 2008
Chine

To assess sustainability of rural management in the Changjiang River basin, human behavioral (food consumption, lifestyle pattern, and human waste disposal) impact on nitrogen flow was quantitatively evaluated. A survey of day-to-day activities was conducted in two representative counties: Taoyuan and Taihe. Daily nitrogen intake from food per capita and potential nitrogen load from human waste on the environment were calculated. The former in Taoyuan and Taihe was 17.0 and 16.0gN, respectively.

Effects of seed mixture and management on beetle assemblages of arable field margins

Journal Articles & Books
Décembre, 2008

Beetle assemblages and their response to plant community composition and architectural structure were monitored from 2002 to 2006 within arable field margins. Field margins were sown with either tussock grass and forbs, fine grass and forbs or grass only seed mixtures. After an establishment year, field margins were managed using standard sward cuts, scarification, or graminicide application. For predatory beetles, overall density was greatest where tussock grasses were included within the seed mixtures, while the densities of phytophagous beetles were greatest where forbs were present.
