The spatial heterogeneity of grazing pressure on extensive rangelands has management implications (Adler et al., 2001) but it has traditionally been difficult to quantify. Combination of technologies based on GPS (Global Positioning System) and GIS (Geographic Information Systems) is a quantum leap in our ability to address this issue. These tools were used to estimate the spatial heterogeneity of grazing pressure at a farm scale, and examine the relation between local landscape features and local grazing pressure.
Effects Of Landscape Structure On Plants Species Richness In Small Grassland Remnants In Two Different Landscapes, S. A. O. Cousins, O. Eriksson
Effects Of Landscape Structure On Plants Species Richness In Small Grassland Remnants In Two Different Landscapes, S. A. O. Cousins, O. Eriksson
IGC Proceedings (1997-2023)
There is an increasing interest in using the landscape as the operational scale in many ecological studies. Current species richness in the landscape may be explained by past land use, and habitats may harbour species favoured by an environment that no longer exists. In this study we have included both a landscape scale and a temporal scale. The objective was to explain species pattern and the effect of isolation, habitat size and surrounding land use, and past land use change, on small grassland remnants in rural landscapes.

Forage management has been an important human activity since the beginning of civilization. By comparison, the personal computer has been available only in the immediate past. The software developed to deal with the complexity of climate, soil, plant, animal, and socioeconomic factors has seen huge changes in a few decades. Mainframe computers facilitated numerical calculations for exploring relationships among dozens of variables. Personal computers opened the door for more individual scientist creativity and routine communication. Web-based communication globalised the option for multidisciplinary teams to tackle problems. Forage-related computer applications abound, allowing farmers, ranchers, and others to more effectively manage the …

Grazing lands (non-arable terrestrial ecosystems) play a vital role in the rural economy and environmental conservation. Modern tools in which, GIS, GPS and satellite remote sensing play vital role in the assessment, characterization and management of grazinglands (Paul et al., 2010). The present study aims to assess the physical conditions and distribution pattern of permanent pastures and other grazing lands in arid Rajasthan using remote sensing and GIS techniques. Though grazing lands do occur in a number of habitats, the study has focused on those sites which have water resources for its rational utilization for pasture/grassland development. Rapid advances in …

Livestock acquires special importance in mountain farming system from both ecological and socioeconomic point of view. They are an integral part of the farming system and a “bridge’’ connecting two types of land viz., forest and cultivated. In hilly regions, the arable agriculture is not very remunerative; therefore farmers of all categories rear sheep, goats, cattle etc. under sedentary, semi-migratory and migratory systems to supplement family income (Dev et al., 2014). The common property resources (CPR) and degraded pasturelands are the major feed sources. Remotely sensed satellite imagery and Geographic Information System (GIS) are being widely used for the …

The spatio-temporal condition and trend of grasslands in India at village-level is still not known completely. Historical and contemporary monitoring and assessment protocols are primarily based on the wisdom, knowledge and experience of village-level revenue officer (patwari) which is just significant from the statistical point of view. Contrastingly, such grassland areas are considered to be of high priority by government authorities for the long-term conservation of biodiversity. Protection, development and sustainable use of grasslands are very important for the rural economy and livestock. The major grasslands now survive west of isohyets 200 to 250 mm rainfall where livestock …

Using Gps And Gis To Engage Students In High-Impact Educational Practices (Hiep); A Case Study In Bahia Ballena, Costa Rica, Austin Riegel
Student Symposium
One issue that many teachers face today is teaching students that are not English heritable speakers. In the past couple decades there has been a sharp increase in the amount of non-native English speakers in the classroom; making it important for new teachers to be able to relay information to the students when they don’t speak the same language. Over Spring Break (2019), I visited Costa Rica to work with a 6th grader class that spoke mainly Spanish -- I don’t have formal training in Spanish. We employed various high-impact educational practices and hands-on activities (e.g., drone flying, mapping with …
Use Of Floodscape Mapping To Assess Changes In Inundation Frequency Of The Upper Mississippi River, Jeffrey L. Swanson
Use Of Floodscape Mapping To Assess Changes In Inundation Frequency Of The Upper Mississippi River, Jeffrey L. Swanson
Celebration of Learning
As an alternative to probability-based maps, DeJager (and others) reconceptualized floodplain mapping using the notion of “floodscapes” (DeJager et al., 2015). A floodscape map is developed using daily stage data and high-resolution topography to create maps that depict the average number of days of inundation (per year or growing season). Floodscape maps reveal intricate and continuous patterns of high-frequency flows that are critically important to floodplain ecological functioning. DeJager found significant correlations between floodscape inundation and riparian vegetation patterns but single floodscape maps only provide snapshots in time. This current research develops and utilizes multiple floodscape maps to quantify changes …

Assessing The Impacts Of Toxic Mixtures Over A Broad Geographic Scale: Challenges And First Steps, David Hugh Baldwin, Julann A. Spromberg, Jessica I. Lundin, Cathy A. Laetz, Nathaniel L. Scholz
Salish Sea Ecosystem Conference
Assessing the risks posed by chemical mixtures is a complex process. Ideally, details are available on exposure (e.g. which chemicals and what concentrations) and effects (e.g. mechanisms of action and toxicity data). This can be challenging even for a single location and time such as a lab or field site. Ecological risk assessments often need to cover much larger scales such as an entire watershed or a wide-ranging species. This increase in scale substantially increases the complexity. Thousands of chemicals in use lead to potential environmental mixture exposures, including pesticide runoff and municipal wastewater discharges. At the landscape scale the …

Morel mushrooms, Morechella esculenta and M. deliciosa, are known delicacies across the globe, ranging from exquisite dishes in French cuisine to Eastern palates such as Japanese Matsutake. According to literature, true morels diverged as their own genus about 129 million years, again which has led to the development of more than 177 species and have been part of the human diet since their beginning. However, the elusiveness of morels has contributed to the mushrooms infamy for rarity, and has even been known to sell for more than $40 per pound. This project seeks to aid in the search for morels …

The most fundamental human needs of water are for drinking, cooking and personal hygiene. In order to fulfill these needs, the quality of the water used should cause no risk to human health. The quality of the water in nature also affects the condition of ecosystems all living organisms depend on. At the same time, humans use water bodies as convenient sinks for the disposal of domestic, industrial and agricultural wastewaters. This, of course, degrades the quality of those water bodies. Water resources management involves the monitoring and management of water quality as much as the monitoring and management of …
