Disappointing Habitat News

A few days ago I shared images of prairie smoke (also known as “Grandfather’s Whiskers”) that bloom along a local road. The small plants probably are not noticed by most people and that is likely good for their survival. Unfortunately, they face another survival challenge.     

When I drove by the plants today, I noticed the right-of-way (ditch) had been mowed. I don’t mind ditch mowing (or cutting for hay), but I do think it should be done according to guidelines found on the Iowa DOT website ( 

“Iowa law prohibits mowing of roadside vegetation on the right of way or medians of any primary highway, interstate highway or secondary road prior to July 15, except:

  • Within 200 yards of an inhabited dwelling.
  • On right of way within one mile of the corporate limits of a city.
  • To promote native species of vegetation or other long-lived and adaptable vegetation.
  • To establish control of damaging insect populations, noxious weeds and invasive plant species.
  • For visibility and safety reasons.
  • Within rest areas, weigh stations and wayside parks.
  • Within 50 feet of a drainage tile or tile intake.
  • For access to a mailbox or for other accessibility purposes.
  • On right of way adjacent to agricultural demonstration or research plots.

The Iowa DOT has established two periods for harvesting grass within the state-maintained highway right of way. 

  • July 15-Sept. 1: For cool-season grasses and forage legumes (e.g., smooth brome, tall fescue, perennial ryegrass, alfalfa, bird’s-foot trefoil)
  • July 15-Aug. 15: For areas containing warm-season native grasses (e.g., switchgrass, big bluestem, little bluestem, Indiangrass, sideoats grama, Canada wildrye)

The Iowa DOT may restrict operations or define additional stipulations in the permit, including those that affect the health of vegetation. Mowing of newly seeded areas that are not yet fully established will not be permitted. (It can take four to five years following seeding for an area to become fully established.) 

All work shall be performed between 30 minutes after sunrise and 30 minutes before sunset. Work that is performed between the road and ditch bottom requires traffic control. All personnel must wear approved safety apparel, which the Iowa DOT will provide for the applicant when the permit is approved. 

The Iowa DOT makes no guarantee as to the quality and quantity of the hay, or presence of any toxic materials or other contaminants. Applicants should check with the local Iowa DOT maintenance facility for herbicide application records. 

Iowa DOT Form 810050 – Harvesting and Mowing Permit Application covers three types of operations: (1) mowing only; (2) harvesting hay in large or small bales; or (3) harvesting plant material other than hay with machinery, by hand or with hand tools. This form is also available from any of the representatives listed below. 

It is necessary for abutting property owners to sign off on all permits before department approval. 

Contact the representative serving the area nearest where you would like to harvest hay to receive assistance in processing your permit application.

On a positive note, I did see this male dickcissel singing from a power line today.

At home we have a very fragrant shrub that will likely lose its blossom if the rain arrives as predicted.
