In this painting, Drum seems to have focused on the tangled growth and vibrant interplay of colors that define wetland vegetation. His use of color is particularly notable for its intensity and variety, suggesting a place that is not just alive, but thriving with diverse plant and perhaps even animal life.

The technique appears to be loose and expressive, which is often used to convey the feeling of a place rather than an exact replica of its appearance. The crisscrossing of brushstrokes and lines may represent the intertwined vegetation often found in wetlands, while the splashes of color could signify flowers, leaves, or the changing hues of the seasons.

The abstract nature of the painting invites personal interpretation and emotional response, which is a characteristic of impressionistic and expressionistic art. The viewer might feel the movement of wind through the trees or the warmth of sunlight filtering through the canopy, highlighting the sensory experiences one might have in such a setting.

Overall, Drum's Niagara Wetlands is a dynamic and engaging piece that serves as a tribute to the natural beauty and importance of wetland ecosystems. It can also be seen as an invitation to contemplate the role of such environments in our world, and our relationship to them.
