Wild parsnip (Pastinaca sativa) is a plant that can pose several dangers to humans and animals due to its toxic sap and other characteristics.
Wild Parsnip is most often found in areas exposed to full sun, although it can grow in the semi-shade of forests and riverbanks. It is tolerant of a variety of soils, but can not survive in flooded environments. In Canada, Wild Parsnip is most often found in disturbed areas (i.e. railway embankments, roadsides, trails, shorelines, ditches, beaches, forest clearings and areas such as abandoned mine sites, quarries, and waste areas). Some of the less common sites include cultivated fields, gardens, meadows, swampy lowlands and grassy areas.
Wild Parsnip invades disturbed areas such as roadsides, pastures, crop land and fields with reduced tillage use. lIt outcompetes native vegetation, particularly crowding out lower-growing plants. It can also have an impact on pollinators, as honeybees do not visit the plant and it may displace other, more pollinator friendly plants, such as goldenrod.
Wild Parsnip can reduce the quality of some agricultural forage crops. In agriculture operations using no-till or reduced tillage system it is a concern as perennial weeds such as Wild Parsnip are able to take Over.
It is not valuable as a forage plant, and in fact the chemical compounds in Wild Parsnip inhibit weight gain and fertility in livestock that feed on it.
Beware of Wild Parsnip! It Burns The Skin!
When bare skin comes into contact with any part of wild parsnip it can be “burned.” Skin will redden, and in severe cases, blisters will form 1-2 days after exposure. Brown scarring can last for several days to years.
Wild Parsnip contains toxic compounds within the plant called furanocoumarins. These toxins, when in contact with skin, can cause serious rashes, burns or blisters if exposed to sunlight.
To protect yourself from the dangers of wild parsnip, take the following precautions:
If you come into contact with wild parsnip sap, immediately wash the affected area with soap and water and avoid sun exposure for a few days. Seek medical attention right away if you experience severe skin irritation or any other concerning symptoms after coming into contact with wild parsnip. If the plant is a known invasive species in your area, consider reporting its presence to local authorities or invasive species management organisations.
