NATURE-<br />

NEAR CITY<br />

PARKLAND<br />

More usually, round balers are to be seen on<br />

farms or in an agricultural contractor’s fleet.<br />

There’re seldom used on municipal green<br />

areas. But the city of Dortmund proves the<br />

exception.<br />

Westfalenpark in Dortmund. While<br />

the morning commuters join the<br />

traffic jams on the adjacent B 54, a team<br />

from the city parks department get to work.<br />

A sizeable patch of meadow landscaped<br />

around a road junction must be mowed. But<br />

not, as in earlier years, using a cost-efficient<br />

and speedy mulcher. Instead, a tractor and<br />

cutterbar mower go into action. Admittedly,<br />

the equipment is not as simple as a mulcher.<br />

But substantially less insects fall victim to<br />

the mowing operation. “A few years ago,<br />

we changed the way we look after our<br />

grassland areas and started extensive<br />

methods”, says Jürgen Hundorf, planner<br />

in the Dortmund Parks Department, responsible<br />

for a total 400 ha within the city<br />

precincts. Nowadays, around half of this<br />

is managed extensively. “These areas are<br />

cut twice yearly with cutterbar mower”,<br />

says Soenke Janssen, agricultural master<br />

craftsman and responsible within the parks<br />

department for the Technical Service West.<br />

The changeover from mulching to cutterbar<br />

mowing is, however, not the only adjustment<br />

in machinery used. Whereas the<br />

mulched vegetation is left lying on the surface,<br />

the cut grass has to be removed after<br />

a few days. Firstly, it’s swathed by a tractor<br />

mounted band rake, then round baled.<br />

Especially for this, the Park Department in<br />

early 2<strong>02</strong>0 bought a Krone Bellima F130. The<br />

investment in the machinery needed for an<br />

organically managed parkland system is not<br />

insignificant, but is necessary”, emphasises<br />

Soenke Janssen. There was no resistance to<br />

the required investment.<br />

THE RIGHT KIT<br />

The Bellima F130 represented the baler<br />

Soenke Janssen really wanted when the<br />

tenders were submitted. “The round baler<br />

is comparably light, very compact and suits<br />

very well our communal tractor, which is<br />

smaller than the tractors used on farms”,<br />

he explains.<br />

The new Dortmund biodiversity is especially<br />

impressive taking the example of wildlife<br />

on the meadows around a housing district<br />

in the southwest of the city. The meadow<br />

flowers in widely varied colours were in the<br />
