The use of biomass crops as an energy source is frequently mentioned as an option to reduce CO 2 emissions. To evaluate the possibilities reliable yield estimates of biomass crops are required. In this paper a simple method is developed to estimate regional yields of various biomass crops, based on the linear relation between intercepted light and biomass production. The quality of the estimates was studied by using the method to estimate yields of several agricultural crops in two regions in The Netherlands. In general a deviation of less than 10 % was found between actual and estimated average yield.
The cumulative effects problem in natural resource management and land use planning stems from the difficulty of demonstrating that while each single land use change results in a negligible impact, the accumulation of these individual changes over time and within a landscape or region may constitute a major impact. This paper details a general approach to estimate the cumulative effects of land use change on wildlife habitat using Summit County, CO, USA as a case study. Our approach is based on a functional relationship between effect on habitat and distance from development. Within this building-effect distance, habitat is assumed to be degraded, producing a disturbance zone. We sum the total area within the disturbance...

For more information about how these data were developed, please see the final report. Expert opinion was used to define a resistance surface for each of the target animals, with higher resistance representing map units expected to be more difficult and more dangerous for species to move through. A set of nodes for each species, with node points indicating center locations for potential source populations for the species, are also defined. Note actual species population data to define the nodes is not used, as that data was often unavailable, and the focus is on the potential spread of the species across the SALCC region and not limited to models to known populations. Therefore, node locations were determined by...

The PFLCC has recently completed a set of comprehensive conservation planning scenarios for the state of Florida. This represents the first statewide effort to assess likely alternative futures for conservation considering an array of financial, biological, climatological and urbanistic conditions. These spatially explicit and temporal scenarios simulate both urban growth and climate change and identify the most suitable areas for conservation given the resulting land use pattern. Conservation allocations are based on both fee-title and conservation easements.The conservation priorities and mechanisms expressed in these scenarios are based on a wide set of contributing factors, and simulated conservation is purposefully...

Sagebrush Conservation Design (SCD) applications are limited by the capacity of land managers to integrate maps of rangeland condition and threats into planning processes for their management area. To increase the integration of spatial data and help managers and planners step down the SCD to local-scale conservation planning, we developed a web application that provides a user-friendly interface.The layers published here include levels of threats (annual grass cover, tree cover, human modification index) and desired habitat variables (perennial grass cover, sagebrush cover). Percent cover of sagebrush, perennial grass, invasive annual grass, and trees, and the human modification index were originally obtained from...

Past climate changes have led to considerable changes in the species composition of ecosystems. The recent increase in average global temperature is rather strong compared to previous warming periods and, if climate models are correct, future warming will be even stronger. Especially in Europe where the landscape has been greatly fragmented by human activities, the ongoing and projected changes in climate will pose an additional stress on the natural biodiversity. This paper will discuss a method for the selection of bio-indicators to assess the possible landscape-ecological effects of climate change, and presents some preliminary results of the selection of indicator species for the Netherlands.

The connectivity result files from Circuitscape represent the "adjusted cumulative current density" flowing across the landscape for each of several species, at a 90-meter resolution across the South Atlantic Landscape Conservation Cooperative region. Rasters are classified using quantiles with 20 categories (each 5% of region) to integer scores from 1-20. 1 = lowest 5% of the landscape, 20= top 5% of landscape Expert opinion was used to define a resistance surface for each of the target animals, with higher resistance representing map units expected to be more difficult and dangerous for species to move through. A set of nodes for each species, with node points indicating center locations for potential source populations,...

Climate change results in an alteration of spatial and temporal patterns of climate hazards. The trend in weather related disaster seems upward. Various socio-economic sectors are affected by these changes, e.g. the disaster reduction institutions and the insurance industry. We report about an ongoing project addressing the vulnerabilities of sectors affected and policy options in various sectors, notably "Storms over NW-Europe", "the insurance sector" (both as a sector impacted by change and as a mechanism to cope with risk) and "cyclones in the South Pacific".

In the Pacific Northwest, land and resource managers strive to make decisions that benefit both natural and human communities, balancing ecological and economic demands including wildlife habitat, forest products, forage for grazing, clean water, and wildfire control. Climate change adds a layer of complexity to the planning process because of its uncertain effects on the environment. In order to make sound decisions, managers need information about how climate change will affect wildlife habitat, both on its own and in conjunction with management actions. The goal of this project was to explore how future climate may interact with management alternatives to shape wildlife habitat across large landscapes. Scientists...

Broad Ecosystem Inventory Classification provides broad regional information about the distribution of ecosystems throughout the province and the value of these ecosystemsto wildlife. This is done in order to facilitate the use of wildlife information in broad regional land and resource planning initiatives.Broad Ecosystem Units are mapped based on imagery of the provincialland base generally captured at a scale of 1:250,000.
