Conservation Practices for Landlords
There is growing concern over the possible impact of rented land on soil conservation. Concerns regarding conservation practices are not new; however, the recent increase in concerns has come about for several reasons. More than half of Iowa’s farmland is rented and operated by someone other than the owner. In addition, landowners are aging and therefore are less likely to be actively engaged in farming. The general assumption people have is if a farmer does not own the land they farm, they are less likely to have an incentive to use conservation practices.
Conservation Practices in Lease Agreements
The purpose of this lease supplement is to encourage cooperation between tenants and landlords to obtain and maintain needed conservation practices on a rented farm. Rent charges should reflect cost and risk incurred by farming practices. Conservation practices and improvements will not be made unless agreed to in advance and the tenant has the necessary machinery and management ability.
Considerations for Prescribed Burning: Ignition Techniques
When initiating a prescribed fire, it is important to determine the type of ignition pattern, or combination of patterns prior to the burn. Making this determination depends on several factors: burning objectives, fuel characteristics, pre- and post-burn weather, smoke management, manpower and equipment availability, and adjacent fuels.
Considerations for Prescribed Burning: Timing a Prescribed Burn
Prescribed fire is a tool utilized under very specific and predetermined conditions to manipulate the environment and achieve a desired outcome. Fires helped to control unwanted pests, and to increase safety around the living areas by increasing the visibility. Learning from the past, land stewards now use prescribed fire in forests to manage vegetation, improve wildlife habitat, and control pest problems.
Considerations for Prescribed Burning: Tools & Safety Gear
Prescribed fire is one of a suite of tools used to manage landscapes to achieve specific management goals. Safety in using prescribed fire is of utmost importance. To conduct a safe and effective prescribed fire requires not only a burn plan and clear lines of communication, but also the right equipment and a crew who know how to safely use that equipment and employ the correct firing techniques.
Developing a Prescribed Fire Burn Plan: Elements & Considerations
Burn plans are a critical component of any prescribed burn. The purpose of a burn plan is to provide a description of the burn area, target weather conditions, hazards that may be encountered, personnel needs and safety and contacts to make prior to burning. This publication includes a burn plan template and explains the importance and purpose of each section of the template.

It provides information on site selection, preparation and establishment, management and seed mixes.
Farm Ponds -- Managing Iowa Fisheries
Ponds are, at times, both complex and simple ecosystems. Pond complexity depends on the food webs involving many types of organisms. This publication addresses concerns of landowners who wish to continue to enjoy their farm ponds.
Fire in Grazing Management: Patch-Burn Grazing
Fire is a critical natural process necessary for maintaining ecosystems around the world, providing a means for renewal, regrowth and maintenance of habitats. In grassland and savanna ecosystems, fire plays an important role by limiting encroachment of wood species and cycling nutrients; however, in nearly all grassland and savanna habitats fire was not the only process at work. Historically, fire was closely coupled with grazing – namely by large mammals.

Mammals of Iowa Field Guide
Iowa has a rich diversity of mammals, ranging in form and function from the one third-of-an-ounce western harvest mouse which summits blades of grass to eat seeds in Iowa’s prairies to the over 1,000 pound bison whose diet shapes the community of grasses on which it grazes. Our fellow mammals enrich the lives of Iowans from city lots to rural farmsteads. Few sights rival that of a flight of bats at dusk on a warm summer evening, the passing flash of a gray fox in the headlights on a night drive, or the beauty of a herd of snow-covered white-tailed deer on a winter day.
