|
If ornamental jewelweed (Impatiens glandulifera) displaces perennial vegetation along water bodies, soil erosion is likely to occur.

Anecdotal
|
N/A
|
The adventitious roots of ornamental jewelweed (Impatiens glandulifera) can obstruct waterways and wetlands, which can alter the hydrology of the ecosystem. This altered hydrology can lead to increased erosion or flooding.

Field
|
A larger sediment load in the river from the establishment of ornamental jewelweed (Impatiens glandulifera) could, in turn, reduce available habitat and smother benthic communities.

N/A
|
At maturity, ornamental jewelweed (Impatiens glandulifera) is taller and has relatively larger leaves than most grasses and forbs. This shading effect creates bare patches nearby, facilitating germination and emergence of additional I. glandulifera seedlings.

Field
|
The stems of ornamental jewelweed (Impatiens glandulifera) have a high holocellulose content (insoluble carbohydrates) that does not fully decompose over the winter. As a result, litter still present in the spring can suppress other plant seedlings.
