Windbreaks | Natural Resource Stewardship
Windbreaks provide many benefits. They reduce wind speeds, control snow drifting and accumulation in farmsteads, provide wildlife habitat, enhance farmstead value, and provide a more pleasant environment. Learn more about the planning, establishment, maintenance, and care of windbreaks from the Natural Resources Forestry Extension Specialists.
Master Conservationist Program | Natural Resource Stewardship
The Master Conservationist Program is a collaborative program offered by ISU Extension and Outreach, County Conservation Boards, and local conservation leaders and professionals. The intensive blended online and in-person curriculum is developed to equip Iowans interested in natural resource conservation with the knowledge and skills necessary to make informed decisions about natural resources and to become local leaders and educators.
Landscaping for Wildlife | Natural Resource Stewardship
Attracting wildlife to the backyard is easy by providing what they need: Habitat. Habitat is made up of four factors: 1) food, 2) water, 3) shelter, and 4) space. Each factor is essential for a good habitat and varies somewhat by the species of wildlife and the season. To ensure the greatest variety of wildlife species, provide a yard with the largest variety of food, shelter, and cover by providing different types of plants, feeders, and houses.
Managing Problem Wildlife | Natural Resource Stewardship

Tree and Shrub Care
Maybe you’ve never given them much thought, but trees are everywhere.  They’re in our yards, parks, cemeteries, natural areas, along our streets…yes, everywhere!  And even if you don’t always notice them, we need them.  We need them to clean our air, provide shelter from summer heat and winter winds, and bring beauty to our world. This page is meant as a resources for those seeking information on everything from the planting stage all throughout the lifecycle.

Soil Testing Resources for Home Gardeners | Horticulture and Home Pest News
Soil tests for home lawn and garden settings in Iowa can be submitted to neighboring state universities and private laboratories.  Soil tests are not available from Iowa State University. Where can I submit a soil sample for testing? Many soil testing laboratories provide soil tests specific to agronomic (field) crops.  These labs generate recommendations for field crops that do not apply to the home garden, lawn, or vegetable garden. 
Agriculture and Natural Resources | Iowa State University Extension and Outreach
Agriculture is important to Iowa. We grow crops and raise livestock to feed our nation and beyond. Much of Iowa’s economy thrives on our rich agricultural heritage and ANR Extension and Outreach plays an important role in providing research-based information and resources to educate Iowa’s farmers, producers and agribusinesses. Our programs impact all Iowans, whether they live in a rural or urban area, and have been developed to improve our quality of life.
Plant and Insect Diagnostic Clinic
The Plant and Insect Diagnostic Clinic provides diagnosis of plant problems (plant diseases, insect damage, and assessment of herbicide damage) and the identification of insects and weeds from the field, garden, and home. The PIDC is a joint effort between Iowa State University Extension and Outreach and Departments of Plant Pathology, Entomology, Horticulture, and Agronomy.
Master Gardener Program
The mission of the Iowa State University Extension Master Gardener Program is to provide current, research-based, home horticulture information and education to the citizens of Iowa through programs and projects. Through their participation in educational activities, Master Gardeners also increase their own personal knowledge in horticulture. Master Gardeners extend Iowa State University Extension’s consumer horticulture education programs through volunteer activity.
