Representatives of local, state, federal, renovation and establishment is on the and non-profit organizations met in Manhattan, Kansas rise – and for good reason. When to lay the foundation for the advancement of windbreak designed properly, windbreaks can buffer research, outreach, and assistance to support and enhance crops from extreme weather and maintain landowner interest in windbreak renovation, maintenance or increase crop yields. They can also keep and establishment. Workshop participants focused on four soil on the ground, enhance pollinator habitat, produce special areas: training for natural resource professionals; outreach forest products and provide other sustainable agriculture and education for landowners/producers; programs and benefits. But wait, there’s more – when planted as living snow policies to support windbreaks; and critical research. fences, windbreaks improve highway safety, and, when planted around farmsteads, they reduce energy costs. The high level of energy among participants at the Manhattan workshop, and the stories presented in this newsletter, are In order to maximize the ability of farmers, ranchers and examples of a renewed recognition that, in the right place communities to access windbreak information and assistance, and at the right time, windbreaks can continue to fill an a team of forestry and agriculture professionals from across important niche in America’s sustainable agriculture tool kit. the Great Plains held a Great Plains Windbreak Action Windbreaks in the Webinar Library any organizations use webinars to provide training, share information, and promote agroforestry. Because agroforestry is M interdisciplinary, these are archived in many different places. The NAC website contains a webinar library with links to archived webinars hosted by its partners. The library has been updated to contain over 75 recorded webinars covering many agroforestry practices and has filtering and sorting capabilities to help users access the content in which they are most interested.
