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

Journal Articles & Books
Diciembre, 2015
Estados Unidos de América

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
Diciembre, 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
Diciembre, 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.

Integrating biodiversity conservation into land consolidation in hilly areas – A case study in southwest China

Journal Articles & Books
Diciembre, 2012
China

Based on the analysis of land consolidation engineering effects on biodiversity conservation in hilly areas, this study considers integrating biodiversity conservation into traditional land consolidation projects and integration biodiversity conservation measures into land consolidation engineering from the overall planning, land leveling engineering, farmland water conservancy engineering, roads and landscape construction engineering respectively.

Bioregional monitoring design and occupancy estimation for two Sierra Nevadan amphibian taxa

Journal Articles & Books
Diciembre, 2013

Land-management agencies need quantitative, statistically rigorous monitoring data, often at large spatial and temporal scales, to support resource-management decisions. Monitoring designs typically must accommodate multiple ecological, logistical, political, and economic objectives and constraints.

Evaluating sampling strategies and logistic regression methods for modelling complex land cover changes

Journal Articles & Books
Diciembre, 2007
Suiza

1. The role of land cover change as a significant component of global change has become increasingly recognized in recent decades. Large databases measuring land cover change, and the data which can potentially be used to explain the observed changes, are also becoming more commonly available. When developing statistical models to investigate observed changes, it is important to be aware that the chosen sampling strategy and modelling techniques can influence results. 2.

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

Journal Articles & Books
Diciembre, 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.

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

Journal Articles & Books
Diciembre, 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.

Validation of plant diversity indicators in semi-natural grasslands

Journal Articles & Books
Diciembre, 2008
Suecia

The use of plant biodiversity indicators in a nationwide survey of semi-natural grasslands in Sweden was examined by comparing results from the survey with additional in-depth studies of plant diversity at the same 30 sites in southern Sweden. Additional grasslands, that were not subjected to the nationwide survey (i.e. rejected after an initial site selection), were also investigated in order to examine the quality of the initial site selection and to assess to what extent they harboured species rich plant communities.

An evaluation of Side-Manavgat coastal land uses with respect to coastal planning and management

Policy Papers & Briefs
Diciembre, 2009
Turquía

The increase of coastal problems as a result of rapid developments and changes brought new planning and management needs into the agenda. The Integrated Coastal Area Management (ICAM) concept developed under the Mediterranean Action Plan (MAP) includes solutions towards the sustainable use of coastal areas in the Mediterranean Region. Antalya is the province of Turkey with the longest coastline on the Mediterranean Sea. Side- Manavgat coasts of the province are privileged areas with their natural beaches, sand dune forests, rivers and natural and historical relic sites.
