Preliminary Fairbanks Bee Pollinator Protection PlanGlobal declines in pollinator species have been documented in several studies across the United States, Canada, and Europe. Honeybees, bumble bees and Monarch butterflies have been hit particularly hard in the US. This Preliminary Fairbanks Bee Pollinator Protection Plan recommends ways to increase public awareness of the problems facing bees and other pollinators, methods to increase and protect pollinator habitat and steps to take to reduce the use of pesticides. The plan also includes a list of native and nonnative plants that grow well in the Fairbanks area and that are attractive to insect pollinators. Planting these species can greatly increase the local habitat for pollinators. In developing the plan, I evaluated 12 pollinator plans from other areas, learned about local pollinators and their habitat requirements, and surveyed local beekeepers. To create the goals, objectives and actions included in this plan, I combined ideas from each of these three sources plus ideas of my own. The plan is not intended to be implemented by any one individual or agency. Instead, the plan can be used by anyone interested in improving pollinator habitat. If you have a backyard, access to a community garden, or just a few pots or a windowsill, you can create pollinator habitat. In addition to individuals, there are many businesses, government agencies, non-profits and other organizations that may be interested in taking steps listed in the plan to benefit bees and other pollinators.
A farmers guide to evaluate soil health using physical, chemical, and biological indicators on an agricultural field in AlaskaFarmers across Alaska face many challenges. These challenges include climate extremes, wind and water erosion, weed pressure, crop pests, and nutrient-poor soils. Cover crops, crop rotation, crop residue, and tillage management are common conservation practices used to address soil related resource concerns. Research in the continental United States has shown that these soil conservation practices improve soil health. Resource managers are trying to determine the usefulness of soil health indicators to assess conservation practices in Alaska. The objective of this project was to provide Alaskan farmers, conservation planners, and land managers with a background on soil health, soil health indicators, soil health assessments, and the use of conservation practices to improve soil health. Establishing linkages between soil conservation practices and soil health indicators will allow individuals to focus conservation efforts on improving soil conditions, evaluate soil management practices and techniques over time to determine trends, make qualitative comparisons of soil health among management systems, and provide tested measures of soil health (indicators) that will allow farmers and land managers to make more informed resource decisions. Numerous studies were conducted across Alaska to gauge the success of cover cropping, crop rotation, and reduced tillage (no-till). Improvements in physical, chemical, and biological indicators were documented. After one year of study, most cover crops resulted in lower bulk density at the soil surface compared to conventional tillage. Among the cover crop treatments, the perennial forage grass Timothy (Phleum pratense var. Engmo) ranked highest in soil organic matter, soil water content, and improvement to the soil structure. Preliminary data from this project has been gathered to develop an Alaska specific Soil Health Assessment Card and supplementary User Guide.
