Description, Park history, Board of Directors
Protecting native plant and animal species, and the habitats in which they occur, are primary
promote the conservation of native biological diversity.

Many non-native species have been introduced in Indiana, intentionally or accidentally, causing
harmful effects on agricultural lands, waterways, prairies, wetlands, forests and other
ecosystems. Most of these exotic species are invasive and often out-compete their native
counterparts. Many are now inextricable from the local landscape.
In accordance with this mission, the DCNP policy is to:

Promote the growth of native plants which do not harm natural areas or the diversity          
of the park.
Protect and restore the park’s natural areas by eradicating exotic, invasive species
Promote and educate park visitors on the harmful effects of invasive species.
Prohibit the planting or introduction of non-native or diseased native species within the
park, including non-native flowers/plants, animals, unwanted pets, etc.

Some exotic, non-native species of concern include but are not limited to:





















Certain plants, such as Cattails (Typha species) or Poison Ivy (Toxicodendron radicans), are
considered native but can still be invasive and have negative effects and therefore will be
controlled as much as possible.

This policy is intended to provide consistent guidance to visitors to Daubenspeck Park and the
community for any activities that could introduce or cause the spread of invasive species in the
park or the surroundings.

Exceptions to this policy can be made on a limited basis for non-native annuals used to
temporarily control erosion and for research projects. Such exceptions must be approved by the
board before introduction.

The preservation of DCNP as a natural area/habitat is a top priority for the park. The board of
directors must review all plant proposals before actions are taken.
